Product Introduction
LM composite anti-corrosion Waterproof coating It is a two-component emulsion elastic developed by the company coating , mainly used for anti-corrosion and waterproofing of concrete structures. LM composite anticorrosive and waterproof coating is a green anticorrosive and waterproof coating, harmless and pure, which can be applied on the dry and wet surfaces of concrete. The coating after construction is elastic, easy to apply, fast to dry, and strong in adhesion. The successful research of LM composite anti-corrosion and waterproof coatings has added a very good variety of water-based anti-corrosion and waterproof coatings in China.
LM composite anti-corrosion and waterproof coating can be divided into: primer coating and surface coating. According to the requirements of the national standard GB/T50046-2018 Design Standard for Anticorrosion of Industrial Buildings, it can be divided into: Grade I corrosion protection (heavy corrosion protection), Grade II corrosion protection (medium corrosion protection), Grade III corrosion protection (light corrosion protection), and Grade IV corrosion protection (micro corrosion protection). Generally, light corrosion protection is used in sewage treatment plants. For example, light anti-corrosion is divided into four levels (slight level 0.3-0.5), three levels (ordinary level 0.8-1), two levels (enhanced level 1.2-1.5), and one level (especially enhanced level 1.8-2).
Product features
1. Resistance to strong acid, alkali, salt, industrial sewage, domestic sewage, oil, etc.
2. The mechanical properties are excellent and elastic.
3. Harmless, harmless and pure.
4. The dry and wet base surfaces can be constructed, which is simple and safe.
5. High bonding strength.
6. Strong ozone corrosion resistance.
7. Resistance to biological bacteria.
8. After 28 days of concrete carbonization test protected by LM composite anti-corrosion and waterproof coating, the carbonization degree of the high layer is zero.
Physical properties of products
1. LM composite anti-corrosion waterproof coating Film-forming substance Is polytrifluorochlorine ethylene , polyethylene nanometer The mixed liquid system of emulsion, tertiary carbonate and polysiloxane.
2. Polyethylene has good stability, extensibility, water resistance and weather resistance due to rare bonds in the main chain; Polytrifluoroethylene has good acid resistance, alkali resistance, salt resistance and mold resistance; Tertiary carbonic acid is used to react with the inorganic curing agent and graft with the resin to link genetic factors, especially to play a strong bonding role with the concrete surface; Polysiloxane has strong defoaming and wetting effects, which is conducive to the full compatibility of powder and liquid materials, and has good permeability.
3. The powder of LM composite anti-corrosion and waterproof coating is made of ceramic raw materials, graphite and scale raw materials. Ceramic raw materials are one of the stable materials in inorganic powder at present, with low water absorption, and are used in industry to manufacture acid resistant bricks.
4. The flexible film of LM composite anti-corrosion and waterproof coating has a good repair and shielding effect on the micro cracks of concrete; LM coating film has good acid resistance, alkali resistance, salt resistance and mold resistance; The LM film structure is compact and can be directly applied to the pasting of ceramic tiles. As a binder, it forms a continuous anti-corrosion and waterproof film.
