The difference between asphalt and polyurethane, the difference between asphalt and polyurethane?

In our Soprema polyurethane waterproofing coatings are available in two-component and one-component two-component coatings. Two-component AB two ratios, component A is a giant urethane prepolymer containing diisocyanate group (-NOC) made by polymerization reaction of raw materials such as polyether resin and diisocyanate; Part B is a mixture of adhesive bonding agents, accelerators, toughening agents, tackifiers, antifungal agents, fillers and diluents. The one-component is made by using mixed polyether for dehydration, adding diisocyanate and various additives for epoxy modification.

Rubber asphalt waterproof coating using polymer synthesis technology, is a new type of special rubber waterproof coating, adding epoxy resin and resin group to make the product more multi-functional and environmentally friendly, giving the new product more waterproof, anti-corrosion, moisture-proof, mildew-proof and other effects. From the point of view of waterproof effect, asphalt is a water-emulsion waterproof coating, which forms a waterproof film after brushing, polyurethane is a reaction-curing material, and forms an elastic waterproof adhesive film after brushing.

From the point of view of waterproof effect, asphalt is a water-emulsion waterproof coating, which forms a waterproof film after brushing, and polyurethane is a reaction-curing material, which forms an elastic waterproof adhesive film after brushing, relatively speaking, but each project has its own particularity.

What is the difference between one-component polyurethane waterproof coating and two-component polyurethane waterproof coating One-component polyurethane waterproof coating One-component polyurethane waterproof coating is a reactive flexible waterproof coating made of isocyanate and polyether as the main raw materials and various additives. The product has good physical properties, strong adhesion, and cures at room temperature and humidity. 1. Performance and characteristics.

Generally speaking, the biggest difference is metabolism, and generally speaking, this is the case, and everything else is about the same, trust and similar efficacy.

The chemical composition is not the same, their chemical composition, one is organic and the other is polymeric.

From the point of view of waterproof effect, water-based asphalt is a water-emulsion waterproof coating, which forms a waterproof film after brushing, and polyurethane waterproof is a reaction-curing material.

Summary. The difference between the properties of water-based polyurethane anticorrosive asphalt and oil-based polyurethane anticorrosive asphalt is.

1. The difference between dispersed media.

Water-based polyurethane waterproof coating is the use of water instead of organic solvents to become a dispersed medium. The oily polyurethane waterproof coating uses other organic solutions such as isocyanate and polyether to become the dispersion medium.

2. Differences in use.

Water-based polyurethane waterproof coatings are generally used in the consolidation and protection of hydrodynamic strata, soil layer, and surface layer, which can bring good results. The oil-based polyurethane waterproof coating is usually used in the processing of foundations and the water plugging work of shelterbelts.

3. The difference in the elasticity of the consolidated body.

Water-based polyurethane waterproof coating has good elasticity of the consolidated body, so it can be used in the concrete dynamic joint for anti-seepage and plugging function. The oil-based polyurethane waterproof coating contains a relatively small consolidated elasticity, who knows the performance difference between water-based polyurethane anticorrosive asphalt and oil-based polyurethane anticorrosive asphalt.

Hello, I am Life Answerer Pepsi Know-it-all k2, I have served 320 people, I am happy to serve you, and the teacher is answering for you.

The difference between the properties of water-based polyurethane anticorrosive asphalt and oil-based polyurethane anticorrosive asphalt is. 1. The difference between the dispersed medium and the water-based polyurethane waterproof coating is to use water instead of organic solvent to become a dispersed medium. The oily polyurethane waterproof coating uses other organic solutions such as isocyanate and polyether to become the dispersion medium.

2. The difference in use of waterborne polyurethane waterproof coating is generally used in the consolidation of hydrodynamic strata, soil layer, and surface layer, and protective effect, which can bring good results. The oil-based polyurethane waterproof coating is usually used in the processing of foundations and the water plugging work of shelterbelts. 3. The elastic area of the consolidated body is closed to eliminate the waterborne polyurethane waterproof car flushing coating, which has the elasticity of the consolidated body is relatively good, so it can be used in the concrete dynamic joint to prevent seepage and plug the leakage.

The oil-based polyurethane waterproof coating contains a relatively small consolidated elasticity

Summary. At the beginning, China's polyester asphalt was based on tar polyurethane as the main product, with relatively stable performance and good waterproof effect. Due to the strong smell, toxicity and carcinogens of coal tar, it has been strongly opposed by the society and the world.

At this time, some so-called waterproofing experts whimsically concocted asphalt polyurethane waterproof coatings, using petroleum asphalt to make polyurethane. This is a historical mistake, they do not understand the role of tar in polyurethane waterproof coatings, tar has the necessary components for the chemical reaction of polyurethane, which is not present in petroleum asphalt, and the addition of petroleum asphalt to polyurethane only plays a filling role, when in fact most non-tar polyurethanes do not have asphalt components.

Hello. The difference between polyester asphalt and ordinary asphalt is not a difference of one or two sentences. Epoxy asphalt paint.

1. Composition: two-component paint composed of epoxy resin, coal coke asphalt, solvent curing agent, etc. 2. Characteristics:

Fourth, technical requirements: project indicators in the state of the container After stirring and mixing, there is no hard lump and it is in a uniform state. Mixing know-how Can be evenly mixed Construction hand slag performance Spraying barrier-free Drying time h (dry) 24 Appearance of the coating film The appearance of the coating film is normal Applicable period h 3 (25) Bending resistance mm 10 Impact resistance cm 30 Non-volatile content % 50

At the beginning, China's polyester was based on tar polyurethane as the main product, with relatively stable performance and very good waterproof effect. Due to the strong smell of coal tar, toxicity and carcinogens, it has been strongly opposed by the society and the **. At this time, some so-called waterproofing experts whimsically concocted a well-known asphalt polyurethane waterproof coating, using petroleum asphalt to make polyurethane.

This is a historical mistake, they do not understand the role of tar in polyurethane waterproof coatings, tar has the necessary components for the chemical reaction of polyurethane, which is not present in petroleum asphalt, and the addition of petroleum asphalt to polyurethane only plays a filling role, when in fact most non-tar polyurethanes do not have asphalt components.

Asphalt polyurethane and liquid membrane are commonly used building waterproofing materials, and they each have some advantages and disadvantages. Here are some of their key features:
