Embodiment 1

[0029] 1. Weigh 35KG of silicate of component A, 20KG of ethanol as solvent, 40KG of butanol as solvent, and 5KG of water (total weight 100KG), add them into the reaction kettle, and mix under the condition of temperature 40°C-80°C , react for 8-16 hours, filter and pack after passing the inspection.

[0030] 2. Weigh 20KG of acrylic resin of component B, 8KG of polyethylene wax as an anti-settling agent, 12KG of silicone resin as a high-temperature resistant resin, 40KG of aluminum powder, and 20KG of butyl acetate as a solvent (total weight 100KG) , mixed evenly, filtered and packaged after passing the inspection.

[0031] 3. Mix the above-mentioned components A and B evenly in proportion. In practice, take 30KG of component A and 75KG of component B to mix, component A: component B = 2:5, adjust the construction viscosity, filter and carry out construction.

[0032] The two-component high-temperature-resistant paint of the present invention, the paint film is tested, its c...

Abstract

The invention discloses a bicomponent heat resistant coating with semi- IPN structure. It consists of component A and component B. The ingredients and weight percentage of Group A: solvent (ethanol, butanol, n-butyl acetate) 35-65, water 3-6, silicon mofetil 30-60. In the Group B, the ingredients and weight percentage: acrylic acid resin 15-35, heat resistant resin (silicone resin, silicone resin, ethyl cellulose) 10-28, the anti-sink help 5-12, aluminum 15-46, solvents (ethanol, butanol, n-butyl acetate ) 10-20. The ratio of Group A: Group B is equal to (1.8-2.5): (4.2-5.8). The paint through linking the inorganic and organic silicone materials has Si-O-Si inorganic structure, good heat resistance and durability, and Si-C bonds containing organic groups with the solubility and insulation. It has excellent heat resistance, water resistance and weatherability. Under high temperature thermal oxidation, the fracture of organic-based chain merely occurs, and the main chain of Si-O-Si bond is up to 350 deg.C until fracture, so it has a higher thermal stability.

Description

technical field [0001] The invention relates to the technical field of paint making, in particular to a semi-interpenetrating network structure two-component high-temperature-resistant paint. Background technique [0002] Heat-resistant paint (heat-resistant paint) is a special paint that is widely used in high-temperature equipment, such as chimneys, high-temperature steam pipes, high-temperature furnaces, petroleum cracking devices, automobile exhaust pipes, and military equipment. Such metal equipment is oxidized and corroded in a high temperature environment to ensure the long-term use of the equipment. With the rapid development of the national economy, the market for high-temperature-resistant coatings is becoming more and more extensive, and the market demand is great. [0003] In the prior art, technologies related to high-temperature resistant coatings have been introduced into the market one after another. At present, it is common to introduce organosilicon functi...
