Preparation method of water-based crack paint for glass base material

Abstract

The invention relates to a preparation method of a water-based crack paint for a glass base material. The water-based crack paint is composed of a water-based priming paint and a water-based crack finishing paint; the water-based priming paint is composed of acrylic resin, amino resin, a colorant, a dispersing agent, an adhesion promoter, a film-forming auxiliary agent, an acid catalyst, a functional auxiliary agent and other auxiliary agents; the water-based crack finishing paint is composed of acrylic resin, polyurethane resin, amino resin, a colorant, an acid catalyst, a dispersing agent, a film-forming auxiliary agent, a functional auxiliary agent and other auxiliary agents; the prepared water-based crack paint has low VOC, has no pollution to the environment, is nonhazardous to operators, and has the advantages of excellent coating film performance, strong adhesive force, good flexibility, high hardness, good scratch resistance, excellent water resistance, excellent alcohol resistance, simple construction, and stable storage. A coating film crack is a crystallization product integrated with classical art and a modern decoration style, has a unique three-dimensional aesthetic feeling, is elegant in style, and is quite popular with markets and quite loved by customers. The water-based crack paint is widely used for surface protection and decoration of glass products, woodware, metals, plastics and other products.

Description

Technical field [0001] The invention relates to a preparation method of water-based crack paint, in particular to a high-performance water-based crack paint suitable for various glass substrates. Background technique [0002] Crackle paint is a kind of fine art paint, with uniform and beautiful patterns, varied textures, patchy cracks, unique three-dimensional beauty, and elegant style. It is a crystalline product that combines classical art and modern decorative styles. Favored by customers. It can be used for decoration and protective coating of glass, doors and windows, cement walls and furniture, etc., especially suitable for antique simulation decoration. [0003] With the development of society and the improvement of living standards, people's awareness of environmental protection and health has increased significantly, and the requirements for comfort and safety of the living environment are getting higher and higher. Water-based cracking paint has low VOC content, which c...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the cracked paints on the market are still solvent-based, or there are still defects in the performance of water-based cracked paints, such as high VOC content, containing prohibited harmful substances such as alkylphenols, ethylene glycol and ether derivatives, especially in glass substrates. Adhesion, chemical resistance, poor scratch resistance, low hardness, etc., cannot meet the performance requirements of modern glass products such as wine bottles, perfume bottles, etc.
