Internal paint

Abstract

The invention relates to internal paint. The internal paint is prepared from raw materials in parts by weight as follows: 30-35 parts of water-based epoxy ester resin, 5-15 parts of polyimide resin powder, 5-15 parts of bisphenol-A epoxy resin, 2-6 parts of mica powder, 12-15 parts of a pigment, 1-2 parts of BYK-375, 2-3 parts of calcium chloride, 0.2-1.5 parts of BYK-025, 1-3 parts of a curing agent and 25-30 parts of deionized water. With the adoption of the internal paint for containers, coatings can resist the temperature from subzero 20 DEG C to 50 DEG C and has good oil resistance, water resistance, good adhesion, good toughness and excellent corrosion resistance and the low content of VOCs (volatile organic compounds).

Description

technical field [0001] The invention relates to a paint, in particular to a container interior paint. Background technique [0002] Traditional food container paints are mostly solvent-based paints. During the production and application process, a large amount of toluene, xylene and other organic solvents that are harmful to the human body are added, and these solvents are volatilized into the atmosphere, which not only causes waste of resources At the same time, it will cause harm to the health of construction workers and seriously pollute the environment. With the improvement of people's awareness of the environment and the increasingly stringent requirements for environmental protection, it is an inevitable development direction to develop environmentally friendly coatings with low VOC or even zero VOC. [0003] Coatings for the interior of food containers should be tough enough to withstand deformation during container preparation without damage to the coating during tr...
