Problems solved by technology

Most of the HEC thickened paints currently used have insufficient paint film compactness, which is not as good as HASE and HEUR thickened paint films, but the use of the above thickened paint films will reduce the water resistance of the paint

Embodiment Construction

[0014] A kind of high-PVC exterior wall plane latex paint based on HEUR thickener of the present invention, the parts by weight of each component are: 304 parts of water, 4 parts of KPA dispersant, 1 part of FG-5 antifoaming agent, white light color 450 parts of filler, 12 parts of Texanol coalescent, 1.5 parts of polyurethane associative thickener, 100 parts of styrene-acrylic emulsion, 100 parts of pure acrylic emulsion, 2 parts of PH regulator, 2 parts of AMP-19 defoamer, acrylic acid 4.5 parts of thickening agent.

[0015] In the paint formula, KPA, a water-resistant dispersant with coupling effect, is used. KPA has strong dispersion ability, and at the same time, it has excellent compatibility with the system and will not affect the gloss of the coating; potassium salt of acrylic acid copolymer avoids sodium salt Disadvantages of analysis: It has low foaming property and can effectively wet the surface of water-resistant pigments, so there is no need to add additional wet...

Abstract

The present invention discloses a High PVC external wall plane latex paint based on HUER thickening agents, wherein the components comprise, by weight, 304 parts of water, 4 parts of a KPA dispersing agent, 1 part of a FG-5 anti-foaming agent, 450 parts of a white light pigment filler, 12 parts of a Texanol film-forming auxiliary agent, 1.5 parts of a polyurethane association type thickening agent, 100 parts of a styrene-acrylic emulsion, 100 parts of a pure acrylic emulsion, 2 parts of a PH value adjusting agent, 2 parts of a AMP-19 defoamer, and 4.5 parts of an acrylic acid thickening agent. According to the present invention, the water resistance dispersing agent KPA having the coupling effect is used in the paint formula, such that the hydrophobic pigment surface can be effectively wetted, the additional wetting agent is not required, and even the excess dispersing agent can not produce the adverse affect on the system; and the prepared external wall plane latex paint has characteristics of good weather resistance and good water resistance.

Description

technical field [0001] The invention relates to an exterior wall latex paint, in particular to a high-PVC exterior wall plane 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. . Most of the HEC thickened paints currently used have insufficient paint film compactness, which is not as good as HASE and HEUR thickened paint films, but the use of the above thickened paint films will reduce the water resistance of the paint. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a kind of high-PVC exterior wall plane latex paint based on HEUR type thickener with good weather resistance and water resistance and...
