Abstract
The invention belongs to the field of waterproof materials, and in particular relates to a one-component water-based waterproof coating and a preparation method thereof. The composition of raw materials includes: VAE emulsion, environmentally friendly plasticizer, self-crosslinking PVA solution, tung oil, hydrophobic agent, water-based anti-wear additive, polycarboxylic acid mother liquor, water, defoamer, sodium hydroxymethyl cellulose solution, associative Type alkali swelling thickener, associative polyurethane thickener, preservative. The invention uses high-performance VAE emulsion as the main film-forming substance, adds environmental plasticizer and a small amount of tung oil to prepare a single-component water-based waterproof coating, which is convenient for storage and transportation, can be mixed with pure cement at the construction site, and has zero formaldehyde, no odor and environmental protection. Good, and at the same time the paint film has high elasticity. The self-crosslinking PVA solution is prepared, and water-based wear-resistant additives are added to improve the thixotropy, adhesion and wear resistance of coatings, which can be used for exterior wall construction. Sodium hydroxyethyl cellulose is dissolved in mineral oil defoamer to solve the problem of easy agglomeration when added. Add polycarboxylic acid mother liquor to prolong the openness of the coating.
Description
technical field [0001] The invention belongs to the field of waterproof materials, and more particularly, relates to a one-component water-based waterproof coating and a preparation method thereof. Background technique (1) Technical background [0002] Waterproof material is one of the important components of building construction materials. According to the material, it can be divided into asphalt waterproof material, rubber and plastic waterproof material, cement waterproof material and metal waterproof material. With the improvement of modern building requirements, the material selection and construction process of modern waterproofing are becoming more and more standardized, and the water-based cement-based waterproofing coatings represented by polymer cement waterproofing coatings are simple in construction and good in environmental protection. The ratio with cement meets different engineering environments, and has been widely used in waterproof materials in recent ye...
