Embodiment 1

[0020] Below in conjunction with specific embodiment, the present invention is described in further detail:

[0021] The invention is a direct-coating multifunctional interface agent, whose function is to carry out interface treatment on the base layer, improve the adhesion between subsequent materials and the base layer, and avoid large-area foaming during construction;

[0022] Therefore, there will be two construction processes in the embodiment; the present invention can be widely used in old tile bases and aluminum formwork demoulding concrete bases, and can be used outdoors and indoors; therefore, in the embodiments, it will be used on two different bases presented.

[0023] Example 1

[0024] Direct coating multi-functional interface agent, details are as follows (unit: kg):

[0025] Water: 26.26 Styrene-acrylic emulsion: 32 Quartz Sand: 7 2 ~ 6mm polypropylene fiber: 0.07 Ground calcium carbonate: 30 Magnesium aluminum silicate powder: 0.2 ...

Embodiment 2

[0048] Direct coating multi-functional interface agent, details are as follows (unit: kg):

[0049] Water: 26.26 Styrene-acrylic emulsion: 32 Quartz Sand: 7 2 ~ 6mm polypropylene fiber: 0.07 Ground calcium carbonate: 30 Magnesium aluminum silicate powder: 0.2 Lauryl alcohol ester: 1.2 PH regulator: 0.15 Alkyl polyoxyethylene ether: 0.15 Ammonium polyacrylate: 0.4 Propylene Glycol: 1 Hydroxyethyl cellulose ether: 0.4 Mineral oil defoamer: 0.2 Silicone defoamer: 0.15 Alkali swelling thickener: 0.42 Polyurethane thickener: 0.25 Zinc pyrithione: 0.15

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,...
