High-covering-power waterproof impermeable interface treating agent and preparation method thereof

Abstract

The invention discloses a high-covering-power waterproof impermeable interface treating agent and a preparation method thereof, belonging to the technical field of adhesives. 1000 parts by weight of the interface treating agent comprises the following components: 20-30 parts of polyvinyl alcohol, 20-30 parts of corn starch, 20-50 parts of light calcium carbonate, 5-10 parts of titanium dioxide, 100-200 parts of a silane emulsion, 1-2 parts of a glyoxal solution with a mass concentration of 40%-60%, 1-2 parts of an acid solution, 1-2 parts of a dispersing agent, 1-2 parts of a wetting agent, 1-5 parts of an organic pigment, 1-2 parts of a defoaming agent, 1-2 parts of a preservative and water. The interface treating agent disclosed by the invention enables an interface agent adhesive film to be well adhered to a wall surface and form a sealing adhesive film with certain hardness, and has very high covering power and relatively good water resistance. Therefore, the waterproof impermeableinterface treating agent disclosed by the invention has wide application prospects and good market potential.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-hiding waterproof and anti-penetration interface treatment agent and a preparation method thereof. Background technique [0002] The traditional interface agents on the market are made by polymerization or compounding of PVAc system products. Since the PVAc system itself is not water-resistant, it cannot truly achieve moisture-proof and waterproof performance, and the color uniformity and hiding power performance can only be achieved by adding more pigments. To solve the problem, the environmental protection effect cannot be guaranteed. Most of them are used after shoveling the wall and before putting on the putty. effect. Or use this adhesive on the concrete surface to make the base wall surface rough and increase the bonding force of cement mortar to the base. At the same time, it can increase the bonding fastness of gypsum or putty that needs to be leveled on the wa...

Problems solved by technology

In order to overcome this defect, the current remedy methods on the market generally increase the hiding power effect and color degree effect by adding external pigments, or use polyvinyl acetate system adhesives to improve the film-forming effect of colloids, but polyvinyl acetate system adhesives are water-resistant The effect is poor, the hardness of the film is low, and it cannot fully meet the requirements of decoration companies for water resistance, film-forming properties and high hiding power of the interface agent.
