Anti-corrosion weather-proof waterproof paint

Abstract

The invention discloses anti-corrosion weather-proof waterproof paint which is prepared from the following raw materials in parts by weight: 70 to 90 parts of film forming agent, 30 to 50 parts of solvent, 15 to 25 parts of coalescing agent, 10 to 20 parts of pigment filler and 10 to 30 parts of auxiliaries. A preparation method of the anti-corrosion weather-proof waterproof paint comprises the steps: grinding the pigment filler into powder in a ball milling mode; sequentially adding the pigment filler powder, the film forming agent, the solvent and the auxiliaries into a plastic tank; stirring for 8 to 10min until the materials are evenly mixed; stirring for 25 to 28min in a rotation speed of 1500r / min to fully disperse the materials; then adding the coalescing agent to disperse for 3 to 5min in a high speed to obtain a dispersion system; adding sodium hydroxide solution to adjust the pH value to 7.0 to 8.0; evenly mixing to obtain the anti-corrosion weather-proof waterproof paint. The tensile strength and the film hardness of the modified film forming agent are obviously improved, the paint which is prepared from the film forming agent matched with other ingredients has good weather resistance and waterproofness in the outdoor condition, also has the obvious effects of corrosion resistance and high temperature resistance and is simple in preparation process.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an anti-corrosion and weather-resistant 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 indus...

Problems solved by technology

[0005] Present waterproof coatings, specifically for the weather resistance research of waterproof coatings, can be found everywhere. Nowadays, nano-materials are used as raw materials for waterproof materials, which can improve the weather resistance and waterproof performance of coatings. For example, "a double-component 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 of the coating, but its preparation process is complicated, the requirements are high, and it does not have the effect of anti-corrosion and weather resistance
