Problems solved by technology

Among them, the oil-based waterproof coating itself contains volatile harmful substances, which will release a large amount of harmful gases into the air when it is self-drying or reacting and curing; while the waterproof coiled material needs to be heated and baked with an open flame during construction, resulting in a large amount of smoke, which is also prone to fire accidents
Especially in a certain construction area, the above waterproof materials cannot be constructed or cannot meet the construction requirements
[0004] At present, most of the water-based waterproof materials on the market are made of acrylic and styrene resins and mixed with certain powders, which are environmentally friendly. However, the long-term water resistance of most water-based coatings is not satisfactory. Caused a lot of leakage problems

Abstract

The invention provides a polymer cement-based waterproof coating. The polymer cement-based waterproof coating comprises a composition A and a composition B. The composition A is prepared from nonionicvinyl acetate-ethylene copolymer emulsion, nonionic emulsified asphalt and zirconium dibutyl zirconocene dichloride; the composition B is prepared from heavy calcium powder, chromic sulfide and JX-Iwaterproof agent, and the weight ratio of the composition A to the composition B is 1:(1-2.5). The invention further provides a preparing method of the polymer cement-based waterproof coating. The preparing method comprises the steps of firstly, uniformly mixing all the components of the composition A, continuously stirring the components, adding a uniform mixture of the composition B, and continuing to uniformly stir the mixture to obtain the polymer cement-based waterproof coating. After being molded and cured, the polymer cement-based waterproof coating is free of gaps, cracks or lap joint,is good in weather fastness, does not get cracked at minus 25 DEG C or deform at 100 DEG C, and has good surface hydrophobicity. Waterproof components permeating a base layer have the performance of enhancing self-waterproofing for the base layer; meanwhile, the function of self-restoring tiny fractures of the base layer is achieved.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a polymer cement-based waterproof coating and a preparation method thereof. Background technique [0002] Waterproof material is one of the most important materials in building materials. The quality of waterproof materials directly affects the quality and service life of the entire construction project, as well as the living environment of users. To ensure the quality of waterproofing projects, in addition to good architectural design, good waterproof materials are also needed. [0003] At present, the waterproof materials on the market are mainly divided into water-based and oil-based; if classified by appearance, they are divided into coils, coatings and liquids. Among them, the grease-based waterproof coating itself contains volatile harmful substances, which will release a large amount of harmful gases into the air during self-drying or reaction curing; while...
