The difference between fluorine-free waterproofing agent and fluorine-containing waterproofing agent in textile waterproofing agent is mainly in two aspects:

1. Composition differences: fluorine-free waterproofing agents do not contain fluorine, while ordinary waterproofing agents contain fluoride. In addition, fluorine-free water repellent does not contain harmful ingredients such as PFOS, PFOA, and APEO, so it is more environmentally friendly.

2. Performance differences: fluorine-free waterproofing agent has higher washing resistance, and the waterproof effect is still good after many washes, and the fabric is not easy to deform after washing. However, in terms of oil repellency, the overall protective effect of fluorine-free water repellent is not as good as that of ordinary fluorine-containing water repellent agent.

Fluorine-containing waterproofing agent is mainly waterproof, oilproof, anti-fouling, and has a better three-proof effect.

From the characteristics of fluorine-free water repellent analysis.

Fluorine-free waterproofing agent is an environmentally friendly high-performance textile auxiliary, and its main characteristics can be summarized in the following aspects:

1) Fluorine-free: no APEO, PFOA, PFOS, harmless to the environment and human health;

2) Good waterproof performance: excellent waterproof, anti-siphon, slurry permeability, hydrostatic pressure resistance;

3) Good economic benefits: compared with the existing fluorine-based waterproofing agents, most of the fluorine-free waterproofing agents have certain advantages;

At present, there are two alternatives to PFOS and PFOA, one is non-PFOS PFOS, that is, C4 and C6 water and oil repellents, which are less bioaccumulative and toxic than C8 water repellents.

The other is a completely fluorocarbon resin-free waterproofing agent - fluorine-free waterproofing agent, this kind of waterproofing agent does not have oil-proof properties, but it is not easy to be deposited in the organism, easy to degrade, harmless to the human body, there are many types, and it still has excellent application value in the single waterproof processing and finishing of fabrics, and is gradually recognized by many fabric factories and brands.

Waterproofing is the first thing to do when decorating the house, because if the waterproofing is not done well, it will allow us to decorate the house, there will be the possibility of soaking in water, so what kind of waterproof materials do we generally use?Polyurethane waterproof coatingLet's take a look at the recommendations of polyurethane waterproof coating manufacturers and how to buy waterproof coatings.

1. Recommended by polyurethane waterproof coating manufacturers.

1. Shandong Yuen Waterproof Material Co., Ltd. is an innovative building protection system service provider integrating R&D, production, sales, technical services and waterproof professional contracting. The company fully implements the ISO9001:2008 international quality management system, and also passes the ISO14001:

2004 International Environmental Management System Certification and GB T28001:2011 Occupational Health and Safety Management System Certification.

2. In order to meet the growth rate of demand for building materials, the United States Naboshi waterproof is very fast, in 2009, it was authorized to be the head office of Guangzhou Huolun Building Materials as the mainland production base, and the Central Plains Branch "Shangqiu Naiboshi Building Materials", Naboshi waterproof coating manufacturers are a collection of scientific research, production, sales, construction and after-sales service as one of the professional new waterproof enterprises.

3. Chongqing Changshou Zhecheng Coating Factory is a collection of scientific research, production, sales, engineering construction in one of the modern professional waterproof coating factory, our factory strength, advanced technology, strict quality assurance system, product quality has reached or exceeded the national standards issued by the ministry.

Second, how to buy waterproof coatings.

1. If you choose a product that is not environmentally friendly, after the waterproof layer is completed, the harmful gases will be slowly released under the thick floor tiles or cement. Therefore, if you want to buy waterproof materials, you must go to a regular building materials store or supermarket, choose a well-known brand, usually a good brand products are equipped with product test reports. Praise and debauchery.

2. The characteristics are not stiff, generally speaking, the body characteristics of waterproof coatings are divided into two types: rigid and flexible, rigid usually refers to cement mortar, although this kind of product has a high compressive penetration ability after molding, but the extensibility of this kind of product is not very good, there is a little **, ground fracture or small cracks, it is easy to cause water leakage, thus losing the effect of waterproofing. However, the flexible waterproof layer is relatively much better, and the acrylic waterproof coating has good elastic plasticity, which can adapt to the part of the structure to become wild-shaped, so the waterproofness is better.

Qingdao Sanhesheng is a domestic manufacturer engaged in the R&D and production of polyurea. For more than 10 years, Sanhesheng has been devoted to the development of polyurea business, mainly engaged in polyurea, polyurea coating, polyurea anti-corrosion, polyurea spraying, polyurea waterproofing. Polyurea coatings (polyureacoatings) use a one-time coating process, no matter how large the area does not exist, there is no link seam, and it is also a dust-free material polyurea coating, which has the characteristics of strong adhesion, friction resistance and strong hardness.

Qingdao Sanhesheng Polymer Technology Co., Ltd. was established on February 15, 2016. Qiu Xiangjun, the legal representative, the company's business scope includes: research and development of polymer technology.

Processing and sales: chemical raw materials (excluding hazardous chemicals), explosion-proof materials (excluding hazardous chemicals), water-based coatings; waterproofing and anti-corrosion engineering construction; Wholesale and retail: chemical products (excluding hazardous chemicals), mechanical and electrical equipment, spraying equipment and hardware accessories; chemical technology transfer; import and export of goods, etc.

The development history of polyurea coatings: in the polyurethane system, in order to improve the reactivity, a catalyst must be added, which catalyzes the reaction between hydroxyl and isocyanate at the same time, and also catalyzes the reaction between isocyanate and water to produce gas, resulting in a sharp decline in material properties. The polyurea system is completely different, it uses amine-terminal polyether and amine chain extender as active hydrogen components, and the reaction activity with isocyanate components is extremely high, and the reaction can be completed instantaneously at room temperature (even below 0) without any catalyst.

During the construction of two-component polyurethane waterproof coating, only the A and B components need to be mixed, and then applied on the protected base surface, and the A and B components in the mixed coating react and solidify to form a uniform and elastic waterproof coating film.

During the construction of one-component polyurethane waterproof coating, only the coating is applied to the protected base surface, and when the isocyanate retained in the coating reacts with the moisture in the atmosphere and solidifies, a uniform and elastic waterproof membrane can be formed.

Polyurethane waterproof coating has the following advantages: high tensile strength and tear strength of the coating film, excellent mechanical properties similar to elasticity of rubber; Acid-resistant, alkali-resistant, mildew-proof, can be made into flame-retardant coatings, and is suitable for a wide range of temperatures and other excellent chemical properties; High adhesion strength and strong adaptability with various materials; During construction, it is easy to operate, and for large-area construction sites or complex structures, the overall waterproof coating can be realized.

Polyurethane waterproof coating has the following disadvantages: the raw material is more expensive chemical materials, so the cost is higher and the selling price is more expensive; In order to make the thickness of the waterproof coating film relatively uniform, the waterproof base must be required to have a good smoothness, and the construction technology management should be strengthened, and the construction operation procedures should be strictly enforced; There is a certain flammability and toxicity; The two-component must be accurately weighed and matched at the construction site, and the mixing is uniform, which is not as convenient as other one-component coatings; It must be layered and covered up and down to avoid the formation of straight through needle hole pores.

Polyurethane waterproof coatings can be widely used in waterproof projects such as roofs, basements, and bathrooms of buildings, waterproof projects such as storage tanks, swimming pools, and roof gardens, as well as waterproof projects such as tunnels and highways.

Polyurethane waterproof coating refers to the waterproof coating with polyurethane as the raw material, which is suitable for large-area waterproof projects such as swimming pools and roofs, with good hardness and easy to fold, so it is not suitable for places with many pipes and corners.

Waterproof materials can be divided into general-purpose waterproof materials and flexible waterproof materials, it is mainly used for waterproofing and engineering construction waterproofing when we decorate the house, waterproof materials can play a role in impermeability, waterproofing, its general characteristics are strong impermeability, elastic plasticity and extensibility, etc., the southern rain is a lot every year, the following will introduce you to a few high-quality Hunan waterproof material manufacturers for your reference.

Hello classmates:

Polyurethane waterproof coating is a one-component polyurethane waterproof coating made by mixing and polymerizing isocyanate-containing prepolymers formed by addition polymerization of isocyanate, polyether, etc., with catalysts, anhydrous additives, anhydrous fillers, solvents, etc., and processed by mixing and other processes.

This type of coating is a reaction-curing (moisture-curing) coating, which has the characteristics of high strength, high elongation and good water resistance. Strong adaptability to the deformation of the base layer.

Polyurethane waterproof coating is a one-component environmentally friendly waterproof coating with liquid construction, which is based on imported polyurethane prepolymer as the basic ingredient, without additives such as tar and asphalt.

It is a moisture in the air that cures after contact to form a strong, tough, seamless monolithic film on the surface of the base layer.

Hope it helps.

I would like to add a note: Maintain ventilation and fire prevention during construction. Storage and transportation between minus 10 degrees and 40 degrees Celsius to prevent sun and rain, moisture and fire.
