Problems solved by technology

[0004] Now waterproof coatings, researches on the weather resistance and heat resistance of waterproof coatings abound. Nowadays, using nano-materials as raw materials for waterproof materials can improve the weather resistance and waterproof performance of coatings. A two-component water-based nano-waterproof coating and its preparation method", but the cost is extremely high. Due to the complexity of the material composition and the limitation of field conditions when using two-component, the quality is difficult to stabilize; there are also changes in the formula of pigments and fillers to improve The heat resistance and decorative surface of the prepared coating, but the preparation process is complicated, the requirements are high, and the combination is unreasonable and the stain resistance is poor, resulting in the loss of the effect of heat insulation and decoration

Abstract

The invention discloses a color modified waterproof coating which is prepared by the following steps: grinding pigment and filler into powder by a ball milling way; sequentially adding the powder together with a film forming agent, a solvent and an auxiliary into a plastic tank; stirring for 8-10min till uniform mixing; stirring for 25-28min at a speed of 1,500rpm for full dispersion; adding a film forming agent and dispersing at a high speed for 3-5min to obtain a disperse system; adding a sodium hydroxide solution and adjusting the pH value to 7.5-8.5; and mixing uniformly to obtain the waterproof coating. In the invention, the film forming agent is modified to serve as an important raw material for preparing the coating disclosed by the invention, the tensile strength and film hardness are remarkably improved, and the prepared coating has good weather resistance and waterproof property under an indoor condition and has the effects of high-temperature resistance, thermal insulation and decoration; and the preparation process is simple.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a color modified waterproof paint. 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, waterproof coatings ...
