Water-dilutability epoxy woodware transparent primer and preparing method thereof

Abstract

The invention discloses a water-dilutability epoxy woodware transparent primer. The water-dilutability epoxy woodware transparent primer is prepared from main paint and a curing agent. The main paint is prepared from, by mass, 45-65% of epoxy resin, 0.2-0.5% of a defoaming agent, 0.1-0.3% of a dispersing agent, 0.2-0.4% of a flatting agent, 1-2% of an anti-settling agent, 10-30% of filler and 20-25% of a cosolvent. The curing agent is prepared form, by mass, 80% of polyamide and 20% of a modifier. The main paint and the curing agent in the transparent primer exist in a solvent state and can be cured in a humid environment, so that high crosslinking density is achieved, and a formed coating is relatively dense and high in hardness. An emulsifying agent is not adopted in the primer, so that the problem of water sensitivity of waterborne paint is thoroughly solved, the performance of the primer is obviously better than that of common waterborne woodware transparent primers, and the primer can be diluted into solvent paint with a low-toxicity organic solvent under the low-temperature and high-humidity conditions.

Description

technical field [0001] The invention relates to a paint, in particular to an epoxy primer. Background technique [0002] Traditional solvent-based primers are toxic, and harmful solvents such as benzene and free TDI will cause harm to users and affect people's health; with the enhancement of people's awareness of environmental protection, water-based wood paints are non-toxic, environmentally friendly, and non-toxic. Odor, very little volatile matter, high safety of non-flammable and non-explosive, non-yellowing, large painting area and other advantages are more and more popular in the market. However, the water-based wood paint sold on the market, whether it is one-component or two-component, due to the low solid content, leads to a large number of constructions, a long drying time, and the quality of the coating film is greatly affected by manpower and the environment. , high-efficiency coating requirements, can not be industrialized production line, resulting in poor coa...

Problems solved by technology

[0002] Traditional solvent-based primers are toxic, harmful solvents such as benzene and free TDI, etc., causing harm to users and affecting people's health; with the enhancement of people's awareness of environmental protection, water-based wood paints are non-toxic, environmentally friendly, Odor, very little volatile matter, high safety of non-flammable and non-explosive, non-yellowing, large painting area and other advantages are more and more popular in the market

However, the water-based wood paint sold on the market, whether it is one-component or two-component, due to the low solid content, leads to many constructions and long drying time. , high-efficiency coating requirements, can not be industrialized production line, resulting in poor coating effect, poor fullness, poor compactness of the coating film, poor anti-adhesion, low hardness, does not meet the aesthetic requirements of the Chinese people for the coating effect, It cannot meet the coating requirements of high-decorated furniture, and is not conducive to the promotion of water-based wood lacquers
