Abstract

The invention discloses a waterborne acrylic resin and a packaging container coating and a preparation method. The packaging container coating is prepared to solve the problem that the existing waterborne stoving varnish is blistered in thickness and poor in fullness. The preparation method of the waterborne acrylic resin comprises the following steps: adjusting the monomer proportion; modifying through 1, 1-dimethyl-1-heptyl carboxyl glycidyl ester; neutralizing through 2-amino-2-methyl-1-propanol; salifying; and realizing waterborne property to prepare the waterborne acrylic resin which is low in viscosity and good in dispersity to pigments. The preparation method of the packaging container coating comprises the following steps: selecting amino resin; quickly curing without acid catalysis; and preparing a netty crosslinking coating with excellent performance by adopting various pigments and filler. The problem that the waterborne stoving varnish is blistered in thickness is effectively improved, the water resistance of the film is enhanced, the tensile strength is improved, and the fullness of the film is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a water-based acrylic resin, a packaging container coating and a preparation method thereof. Background technique [0002] At present, protecting the environment has become a common issue for human beings all over the world. For paint coating, organic solvents and decomposition products produced in the drying process of various paints are discharged into the atmosphere, causing air pollution and causing great harm. In order to protect the environment, countries all over the world have successively formulated emission standards to strictly control volatile organic compounds (VOC). my country has formulated mandatory standards for the coatings industry. The government's standards on VOC emission limits have played an important role in promoting the technological development of the coatings industry. [0003] The packaging container coating industry is still ...
