Embodiment 2

[0012] A high-efficiency anti-alkali sealed water paint, which is made by mixing the following components by weight percentage: 35% deionized water, 0.2% pH adjuster, 0.8% wetting and dispersing agent, 0.5% defoaming agent, 0.4% preservative, 1.1% antifreeze, 5% titanium dioxide, 2% mica powder, 16% heavy calcium, 35% pure acrylic emulsion, 2% film-forming aid, 2% increase Thickener.

Embodiment 3

[0014] A high-efficiency anti-alkali sealing water paint, which is made by mixing the following components by weight percentage: 20% deionized water, 0.1% pH adjuster, 0.3% wetting and dispersing agent, 0.3% defoamer, 0.3% preservative, 1% antifreeze, 7% titanium dioxide, 4% mica powder, 10% heavy calcium, 55% pure acrylic emulsion, 1% film-forming aid, 1% increase Thickener.

[0015] Among them, the raw material components used in Examples 1-3 of the present invention are specifically:

[0016] The pH adjuster is one of Dow Chemical's AMP-95 (2-amino-2-methyl-1-propanol) and Taminco's Ad-vantex (Avander) pH adjuster (butylethanolamine) Or a mixture of two in any ratio.

[0017] The wetting and dispersing agent is OROTAN CA-2500 from Rohm and Haas, which is a new type of hydrophobically modified ammonium polyacrylate dispersant. The additive has excellent early water resistance, excellent coloring and color development, can make the primer have a wide color palette, and has a wide...

Abstract

The invention relates to the technical field of a water-based coating and specifically discloses efficient alkali-resistant closing water paint. The efficient alkali-resistant closing water paint is prepared by mixing the following components by weight percent: 15%-35% of deionized water, 0.1%-0.2% of a pH regulator, 0.2%-0.8% of a wetting dispersant, 0.2%-0.5% of a de-foaming agent, 0.2%-0.4% of a preservative, 1%-2% of an antifreeze agent, 5%-8% of titanium dioxide, 2%-5% of mica powder, 10%-20% of coarse whiting, 35%-55% of a pure acrylic emulsion, 1%-2% of a coalescing agent and 1%-2% of a thickening agent. The efficient alkali-resistant closing water paint disclosed by the invention has an excellent alkali-resistant closing property, is capable of effectively preventing alkaline matter from exudation and preventing finishing coat from alkali efflorescence and flooding, is high in covering power, is capable of effectively reducing the finishing coat dosage, is capable of meeting the requirement of a client on any colors by toning any colors, is high in storage stability and is high in applicability.

Description

Technical field [0001] The invention relates to the technical field of water-based paints, in particular to a water-based sealing paint. Background technique [0002] The construction base layer of architectural coatings is often mortar concrete. The lime and cement in it have strong alkalinity. With the volatilization of water, the alkaline substances and soluble salts in the cement will pass through the pores of the cement in the form of an aqueous solution. The coating oozes out, and calcium hydroxide is brought to the surface and gradually reacts with carbon dioxide in the air to form insoluble neutral carbonic acid. This white insoluble substance is difficult to remove and easily causes problems such as discoloration, blooming, fading, and peeling of the coating, which seriously affects the decoration and color retention of the coating film. [0003] The prior art uses alkali-resistant sealing primers to improve the above phenomena, but the prior art alkali-resistant sealing ...
