Polyurea is an elastomer substance formed by the reaction of isocyanate components with amino components. In amino compounds, there are hydroxyl components and catalysts, which are called mixed polyureas.

Uses: waterproof and anti-corrosion of underground concrete structures, drainage pipes, etc.; anti-corrosion of steel beams and steel pipes, steel plates, simple silos and storage tanks; parking lots, floors for factories, warehouses and shopping malls; waterproofing and corrosion protection of marine structures, bridge piers and swimming pools; road ramp reinforcement and underground cavern waterproof and anti-corrosion coatings; Foam sculpture protective.

Features: fast curing, can be sprayed on any curved surface, inclined plane and vertical surface, no sagging; Excellent physical properties, superior impact resistance, wear resistance, cold resistance, heat resistance, water resistance and aging resistance; Easy to use, color adjustable, spraying thickness is unlimited; It has good crack bridging performance; Good adhesion to all kinds of substrates; Solvent-free, high solids, safe and environmentally friendly.

The main use of polyurea is as an anticorrosive, waterproof, and wear-resistant material.

Polyurea is a polyamide of carbonated carbon, which is comparable to polyester where polycarbonate is carbonated. The urea group is polar and can form more hydrogen bonds, so the melting point of polyurea is higher than that of the corresponding polyamide, and the toughness is also large, which is suitable for textile fibers.

The best way to synthesize polyurea is to refer to the synthesis method of polyurethane, that is, the dibasic amine reacts with diisocyanate. The reaction is exothermic and can be dissipated by solution polymerization or interfacial polymerization. Because it is a stepwise addition reaction, there are no side reactions, and the polymerization process is relatively simple.

For example, 2,4-toluene diisocyanate is associated with 4,4'-The melting point of polyurea prepared by diaminophenyl ether is as high as 320.

Features of polyurea:

1. No catalyst, fast curing, can be sprayed on any curved surface, inclined plane and vertical, no sagging phenomenon, 5 seconds of gel, 1 minute to reach walking strength.

2. It is not sensitive to moisture and temperature, and is not affected by ambient temperature and humidity during construction (can be constructed under -28; Can be spray-cured on ice).

3. Two-component, 100% solid content, does not contain any volatile organic compounds (VOCs), environmentally friendly, pollution-free construction, and harmless use in sanitary construction.

Polyurea"It is an elastomer substance formed by the reaction of isocyanate components and amino compound components. Generally, it can be divided into pure polyurea and semi-polyurea, and the most basic characteristics of polyurea are anti-corrosion, waterproof, wear-resistant, etc.

Polyurea is extremely versatile. Its application fields are distributed as: concrete protection accounts for 60%, truck wear-resistant lining accounts for 15%, steel structure anti-corrosion accounts for 10%, roof waterproofing accounts for 10%, and others account for 5%.

As a protective technology, polyurea technology is mainly used in four major fields: waterproofing, anti-corrosion, anti-abrasion and surface decoration. For example, the application of polyurea in the territory of pipeline anti-corrosion, pipeline anti-corrosion is also the earliest and largest engineering application of polyurea technology. Applications in other fields include anti-corrosion of steel structures (especially anti-corrosion of steel piles for wharves), elastic anti-collision materials (offshore buoys, string guards).

Protection of nuclear power plants, defense and military industry (tank chassis, bulletproof helmets), swimming pool facilities, etc.

Polyurea is divided into manual polyurea and sprayed polyurea, and manual polyurea is divided into single-component polyurea and two-component aspartal polyurea. The physical strength of all three is very good. Foshan Wanhua Technology produces all three.

Commonly said polyurea is sprayed polyurea, about ten seconds of curing, the need for special professional equipment for spraying construction, one-component polyurea and two-component asparagus polyurea can be roller coating or spraying with ordinary equipment. At present, polyurea is mainly used for waterproof and anti-corrosion projects. It is characterized by long service life, high strength and weather resistance.

Polyurea is made by spraying semi-prepolymers, terminal amino polyethers, amine chain extenders and other raw materials on site. It is extremely hydrophobic, insensitive to ambient humidity, and can even be sprayed on water (or ice) to form a film, and can be applied normally under extremely harsh environmental conditions, and its performance is particularly outstanding.

The emergence of polyurea has completely broken the traditional concept of anti-corrosion and protection, and set a higher standard for the material protection industry. Polyurea coatings are flexible, rigid and colorful, dense, continuous, and seamless, completely insulating from the penetration of moisture and oxygen in the air, and have unrivalled anti-corrosion and protective properties. At the same time, it has a variety of functions such as wear resistance, waterproof, impact resistance, fatigue resistance, aging resistance, high temperature resistance, and nuclear radiation resistance.

SPUA technology is a new type of "all-purpose" coating technology, which is known as the greatest discovery in the field of paint and coating technology at the end of the twentieth century. It combines new technologies, new materials and new processes, and is a revolutionary leap forward in traditional construction technology. It has been applied in developed countries such as North America for more than ten years, and the market demand is very strong.
