Direct coating type multifunctional interface agent

Abstract

The invention discloses a direct coating type multifunctional interface agent, and belongs to the technical field of coating materials. The direct coating type multifunctional interface agent comprises the following components in %age by weight: 20-40% of emulsion, 4-15% of quartz sand, 0.03-0.15% of polypropylene fiber, 0.1-1% of attapulgite, 20-45% of ground calcium carbonate, 15-40% of water, 0.1-0.5% of a wetting agent and the balance of auxiliary agent, wherein the emulsion has relatively strong base permeability, emulsion particles are arranged and self-cross-linked and cured through moisture volatilization, the quartz sand can enable the smooth base layer to form a concave-convex surface so as to increase the contact area with a subsequent coating and improve the bonding strength, the surface of the polypropylene fiber is hydrophobic, and two ends are connected with hydrophobic quartz sand particles to integrally form a net-shaped structure so as to enhance the tensile strength and achieve excellent hole shielding property, the attapulgite provides a good suspension effect, and the wetting agent can quickly wet a base layer and reduce the surface tension of the base layer, so that the material is smooth in construction and free of accumulation.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a direct-coating type multifunctional interface agent for renovating base surfaces of old ceramic tiles or demoulding concrete base surfaces of aluminum membrane panels. Background technique [0002] Since 2000, the domestic home decoration industry has developed rapidly, and the life cycle of most coating materials is 10-15 years. Many old buildings have entered the renovation stage due to backward decoration styles and poor functionality. Among them Some of the building surfaces are old tiles, and the surface is relatively smooth. Generally, direct construction of mortar products and paints will cause poor adhesion, hollowing, and delamination. [0003] At the same time, the technology of the construction industry is also constantly being updated and improved. The wooden boards used to make the formwork when pouring concrete are replaced by aluminum alloy formwork,...

Problems solved by technology

[0005] In view of the existing two-component interface agent, on-site mixing and stirring are required during construction, the efficiency is low, and it can only improve to a certain extent the problem of foaming in the construction of the concrete base of the demoulding of the aluminum alloy formwork, which cannot be cured. The present invention provides a direct Coating-type multi-functional interface agent, directly coated on the renovation base of old ceramic tiles or the demoulding concrete base of aluminum film panels that need to be repaired, without on-site mixing and stirring, with high efficiency
