Environment-friendly water-based crackle coating and preparation method thereof

Abstract

The invention relates to an environment-friendly water-based crackle coating, containing the following components in parts by weight: 5-40 parts of deionized water, 3-15 parts of a film forming auxiliary agent, 4-25 parts of partially alkalized polyvinyl alcohol resin, 4-20 parts of a self-crosslinking vinyl acetate-acrylic emulsion, 0.1-1 part of a wetting agent, 2-8 parts of a dispersant, 5-30 parts of a filler, 0.1-1 part of an anti-settling agent and 0.1-1 part of a pH regulator. The environment-friendly water-based crackle coating has good adhesive force to wood materials, ceramic products and the like, can form a full paint film, has certain hardness and low VOC (volatile organic compounds), does not contain heavy metals, belongs to environment-friendly safe wooden article water-based coatings, and can generate a special crack effect at the same time.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to an environment-friendly water-based cracked coating and a preparation method thereof. Background technique [0002] Traditional solvent paints (commonly known as paints) are harmful to human health and the environment. Especially when used indoors, toxic organic solvents such as benzene continue to volatilize for a long time, directly endangering human health and life safety. For example, volatile organic compounds (VOC) can cause headaches, nausea, sore throat, asthma and other symptoms; free isocyanate (TDI) is an inhaled, accumulative and highly toxic compound that can cause bronchitis, asthma, and even suffocation; Toxic carcinogens mainly affect the hematopoietic system and nervous system; lead makes paints have various bright colors, but the harm of lead to the human body cannot be underestimated. For people who have been exposed to trace amounts of lead for a...
