Problems solved by technology

However, graphene is easily oxidized in a high-temperature environment. After graphene is oxidized, its thermal conductivity will be greatly reduced, which will lead to a decrease in the heat dissipation capacity of the coating.
[0004] Moreover, the viscosity of the paint also has a great influence on the construction effect of the paint. The high and low temperature viscosity and wet heat viscosity of objects such as glass, metal and ceramics all have an impact on the final effect. If the viscosity of the paint is not good, it is easy to lead to long-term use. After the coating ages and falls off, it affects the use of the equipment

Abstract

The invention relates to a high-viscosity polyurethane waterproof coating which is prepared from the following raw materials in parts by weight: 45-90 parts of a polyurethane emulsion, 10-20 parts ofa composite filler, 1-5 parts of a tackifier, 2-5 parts of a coalescing agent, 0.2-1 part of a defoaming agent, 0.5-2 parts of a dispersing agent and 5-20 parts of deionized water. The composite filler is prepared from the components in percentage by weight: 25-35% of vermiculite powder, 15-30% of cordierite micro-powder, 10-20% of lime powder and 20-30% of a heat conduction additive; the tackifier is composed of the following components in percentage by weight: 5 to 15 percent of fatty alcohol-polyoxyethylene ether and 85 to 95 percent of carbomer resin. The unique tackifier component is added into the coating, so that the coating has excellent viscosity and binding force.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, in particular to a high-viscosity polyurethane waterproof coating and a preparation method thereof. Background technique [0002] Paint is a kind of liquid or fixed material that is coated on the surface of an object and forms a thin film under certain conditions to play a protective, decorative and specific role. It has been widely used in daily life. Waterproof coating refers to a kind of coating that the coating film formed by coating can prevent water seepage. The waterproof film formed after the waterproof coating is cured has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof, anti-seepage and protection. [0003] With the development of industry, there are higher requirements for the waterproof and anti-corrosion performance of coatings. In some stages of equipment working in high-temperature...
