Colorized heat-insulating waterproof coating

Abstract

Colorized heat-insulating waterproof coating is disclosed. The coating is prepared by adding a film forming agent, a solvent, an auxiliary agent, an ultraviolet ray absorbing agent and pigment and a filler in order into a plastic tank, stirring the materials for 8-10 min until the materials are fully mixed, stirring the mixture at a speed of 1500 r / min for 25-28 min to fully disperse the mixture, adding a coalescing agent, performing high-speed dispersion for 3-5 min to obtain a dispersion system, adding a mixed solvent including acetone and ethyl acetate in a mass ratio of 1:1 to adjust viscosity, adding a sodium hydroxide solution to adjust the pH value to be 8-9, and fully mixing the mixture to obtain the waterproof coating. The film forming agent is adopted as an important raw material of the coating after the film forming agent is modified, and tensile strength and hardness of film of the film forming agent are significantly improved, and therefore the prepared coating has good weatherability and waterproofness under outdoor conditions and has reflective insulation and decoration functions. A preparing process of the coating is simple.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a colored heat-insulating waterproof coating. Background technique [0002] With the enhancement of people's awareness of environmental protection, water-based coatings have become a popular product in the market. The development and application of waterproof coatings in my country began in the 1960s. In the early days, various chemical wastes were used as raw materials to develop products, but they all stopped due to unstable quality and performance. develop. During the same period, our country also carried out a lot of work on improving the waterproof coating of petroleum asphalt with high polymer. Neoprene-bitumen waterproof coatings appeared in the mid-1960s, and recycled rubber-bitumen waterproof coatings appeared in the early 1970s, and they were successfully applied in engineering. With the steady development of my country's synthetic polymer material industry, waterproo...

Problems solved by technology

Now there are many researches on weather resistance and heat insulation of waterproof coatings. Nowadays, nanomaterials are used as raw materials for waterproof materials, which can improve the weather resistance and waterproof performance of coatings. One-component water-based nano-waterproof coating and its preparation method", but the cost is extremely high. Due to the complex composition of the material and the limitation of the site conditions when using two-component, the quality is difficult to stabilize; there are also improved preparations by changing the formula of pigments and fillers. The heat resistance and decorative surface of the coating, but its preparation process is complicated, the requirements are high, and the matching is unreasonable and the stain resistance is poor, resulting in the loss of the effect of heat insulation decoration
