Hydromagnetic paint additive

Abstract

The invention relates to a hydromagnetic paint additive. The hydromagnetic paint additive comprises the following components in parts by weight: 1-5 parts of polysiloxane, 10-20 parts of butanol, 5-15 parts of alumina, 1-5 parts of hydroxyethyl cellulose, 1-10 parts of ketone, 5-10 parts of ethyl ketone, 10-20 parts of styrene, 5-10 parts of acrylate, 1-5 parts of triethanolamine, 5-15 parts of sorbitan stearate and 5-10 parts of vinyl acetate-acrylic acid copolymer emulsion. The vinyl acetate-acrylic acid mole ratio in the vinyl acetate-acrylic acid copolymer emulsion is 5 / 7-5 / 8. The vinyl acetate-acrylic acid copolymer emulsion greatly improves the pinhole phenomenon of the hydromagnetic paint.

Description

technical field [0001] The invention belongs to the field of decoration coatings, and relates to a water magnetic paint additive. Background technique [0002] In the prior art, due to the poor surface treatment of the board, the wood wool and other phenomena are caused, or the bottom layer is not completely dry, so the second time is applied. Due to excessive thick construction, wrong matching of curing agent and thinner, excessive amount of curing agent added, high ambient temperature and humidity, and high moisture content of wood, it is easy for the surface of the paint to have a pin-point fine hole phenomenon with a hole diameter of about 100 microns. . The water magnetic paint additive containing the vinyl acetate-acrylic acid copolymer emulsion used in the present invention can effectively alleviate the pinhole phenomenon and reduce the pinhole diameter. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to pro...

Problems solved by technology

[0002] In the prior art, due to poor surface treatment of the board, wood wool and other phenomena are caused, or the bottom layer is not completely dry, the second time of construction is carried out. The prepared paint has not been left for a period of time, the paint viscosity is high, and the air bubbles have not been eliminated. Excessive construction, incorrect matching of curing agent and diluent, excessive addition of curing agent, high ambient temperature and humidity, high moisture content of wood, etc., the surface of the paint is prone to a phenomenon of pinpoint pores with a hole diameter of about 100 microns.
