Abstract

The invention discloses a hydrophobic polymer cement waterproof coating and a preparation method thereof and relates to the technical field of building materials. The waterproof coating disclosed by the invention is prepared from a liquid material and a powder material, wherein the liquid material is prepared from the following components in parts by weight: 350-470 parts of the first kind of styrene-acrylic emulsion, 30-150 parts of the second kind of styrene-acrylic emulsion, 1-3 parts of lotus-leaf water repellent agent, 3-6 parts of dispersing agent, 3-6 parts of antifoaming agent, 4-20 parts of deionized water and 0.3-0.8 part of thickening agent; the powder material is prepared from the following components in parts by weight: 200-400 parts of ordinary Portland cement, 150-550 parts of wollastonite powder, 150-350 parts of quartz sand, 2-6 parts of water reducing agent and 1-3 parts of early strength agent; the glass transition temperature of the first kind of styrene-acrylic emulsion is minus 10 DEG C to minus 5 DEG C; the glass transition temperature of the second kind of styrene-acrylic emulsion is minus 20 to minus 15 DEG C. The waterproof coating has the advantages of fast drying, high environmental friendliness and excellent mechanical property.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a hydrophobic polymer cement waterproof coating and a preparation method thereof. Background technique [0002] Most of the polymer cement waterproof coatings are two-component waterproof coatings prepared by adding polymer emulsions such as acetic acid-vinyl acetate emulsion (VAE) or acrylate emulsions and their derivatives and cement as the main raw materials, and adding fillers and other additives. . The physical properties of traditional polymer cement waterproof coatings mostly meet the GB / T 23445-2009 standard, but with the development of the industry, the requirements for practical application performance are getting higher and higher. [0003] Among them, the liquid material is made of acetic acid-vinyl acetate emulsion (VAE) or acrylate copolymerized emulsion. Due to the high glass transition temperature and poor flexibility, it is necessary to add plasticizers to incr...
