Problems solved by technology

However, domestic cement-based waterproof coatings have disadvantages such as poor aging resistance, low tensile strength and elongation, and high and low temperature flexibility due to polymer emulsions; especially for housing waterproofing projects, high and low temperature properties are not good. It is easy to cause aging, cracking, deformation, breaking and rot; especially when construction is carried out under low temperature conditions in the north, the waterproof material is easy to solidify before freezing; therefore, it is urgent to develop a waterproof material that overcomes the above problems to make up for the waterproof market. demand gap

Abstract

The invention discloses a macromolecule polymer emulsion. The macromolecule polymer emulsion comprises the following components in parts by mass: 0.1-2 parts of neoprene latex, 3-4.3 parts of butyl latex and 45-49 parts of ethyl acrylate latex. A preparation method of the macromolecule polymer emulsion comprises the following steps: (1) preparing materials; (2) preparing a first emulsion; (3) preparing a waterproof agent; (4) preparing a second emulsion; (5) preparing an additive solution; and (6) preparing the finished product. A waterproof coating comprises the following components in parts by mass: 36-45 parts of the macromolecule polymer emulsion, 50-58 parts of composite powder and 5-6 parts of additives. The macromolecule polymer emulsion is high in elongation rate; the waterproof coating has waterproof and self-healing functions.

Description

[0001] Technical field: [0002] The invention relates to the technical field of coatings, in particular to a high molecular polymer emulsion, a preparation method thereof and a waterproof coating prepared therefrom. [0003] Background technique: [0004] Waterproof materials are generally divided into flexible waterproof materials and rigid waterproof materials. Among them, flexible waterproof materials have poor aging resistance, weather resistance, and water resistance, and are not suitable for waterproofing the backwater surface and wet base surface; rigid waterproof materials are not suitable for engineering deformation and displacement. waterproof treatment. Domestic polymer building waterproof materials mainly use butyl acrylate, methyl methacrylate, polyethylene and synthetic resin as raw materials. However, these raw materials need to be improved in terms of flexibility and elongation in cold environments. Traditional waterproof materials are toxic and not environme...
