Problems solved by technology

Among them, water resistance is very important for exterior wall latex paints, but most of the paint films thickened by HEC are not dense enough, so it is better to use HASE and HEUR thickened paint films, but the above-mentioned A thickened paint film will reduce the water resistance of the paint
Therefore, there is not much progress in the research on the water resistance of exterior wall latex paints.

Embodiment Construction

[0015] A kind of exterior wall low-PVC latex paint based on water-resistant dispersant of the present invention, the parts by weight of each component are: 170 parts of water, 3.5 parts of KPA dispersant, 2 parts of P-23 water-resistant dispersant, FG- 5 1 part of foam suppressor, 370 parts of white light pigment and filler, 22 parts of Texanol coalescent, 2 parts of polyurethane associative thickener, 400 parts of pure acrylic emulsion, 2 parts of PH regulator, 2 parts of defoamer, acrylic acid 3 parts of thickening agent.

[0016] Due to the use of KPA dispersant and P-23 water-resistant dispersant, KPA has strong dispersing ability, and the excellent compatibility with the system will not affect the gloss of the coating; acrylic acid copolymer potassium salt avoids the disadvantages of sodium salt salting out ; It has low foaming property and can effectively wet the surface of water-poor pigments, so there is no need to add additional wetting agent. Even if this dispersant ...

Abstract

The invention discloses a water resistant dispersant-based exterior wall low-PVC emulsion paint and a preparation technology thereof. The paint comprises, by weight, 170 parts of water, 3.5 parts of a KPA dispersant, 2 parts of a P-23 water resistant dispersant, 1 part of an FG-5 foam inhibitor, 370 parts of a white light pigment filler, 22 parts of a Texanol film forming assistant, 2 parts of a polyurethane associated-type thickener, 400 parts of a pure acrylic emulsion, 2 parts of a pH adjusting agent, 2 parts of an antifoaming agent and 3 parts of an acrylic thickener. The exterior wall low-PVC emulsion paint with good weatherability and good water resistance is prepared through cooperating the KPA and the P-23 dispersant with the polyurethane associated-type thickener and the acrylic thickener.

Description

technical field [0001] The invention relates to an exterior wall latex paint, in particular to a low-PVC exterior wall flat latex paint and a manufacturing process thereof. Background technique [0002] Compared with interior latex paints, exterior wall latex paints are more complex in terms of performance and formula composition. Exterior wall latex paints are generally colored paints, so better weather resistance, water resistance and gloss and color retention are required. . Among them, water resistance is very important for exterior wall latex paints, but most of the paint films thickened by HEC are not dense enough, so it is better to use HASE and HEUR thickened paint films, but the above-mentioned A thickened paint film will reduce the water resistance of the paint. Therefore, there is not much progress in the research on the water resistance of exterior wall latex paints. Contents of the invention [0003] In order to solve the above problems, the object of the p...
