Abstract

The invention discloses a high-viscosity environment-friendly waterproof coating. The high-viscosity environment-friendly waterproof coating is prepared from the following raw materials in parts by weight: 80 to 100 parts of film-forming agent, 40 to 50 parts of solvent, 10 to 15 parts of film-forming additives, 15 to 25 parts of pigment filler, and 15 to 30 parts of additives. A preparation method comprises the following steps: successively adding the film-forming agent, the solvent and the additives into a plastic tank, stirring for 8 to 10 minutes until all materials are uniformly mixed, stirring for 25 to 28 minutes at a rotation speed of 1500 r/min, sufficiently dispersing the materials, then adding the film-forming additives, dispersing for 3 to 5 minutes at high speed to obtain a dispersion system, adding a mixed solvent of acetone and ethyl acetate in a mass ratio of 1 to 1 to adjust the viscosity, finally adding an ammonium hydroxide solution to adjust a pH value to be 7.5 to 8.5, and uniformly mixing, thus obtaining the high-viscosity environment-friendly waterproof coating. The film-forming agent is modified to be used as an important raw material of the coating provided by the invention, so that the tensile strength, the coating film hardness and the viscosity are remarkably improved, and the prepared coating is not only good in weather and water resistance in outdoor conditions, but also remarkable in anticorrosion and high-temperature-resistant effects, and is non-toxic and pollution-free.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-viscosity environment-friendly 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 industr...
