Waterborne two-component acrylic hammer paint and preparation method thereof

Abstract

The invention discloses waterborne two-component acrylic hammer paint and a preparation method thereof and relates to the technical field of paint. The waterborne two-component acrylic hammer paint comprises, by weight, a component A comprising 60-70 parts of waterborne hydroxy acrylic resin, 7-25 parts of deionized water, 3-5 parts of cosolvent, 0.3-0.7 part of wetting auxiliary, 5-8 parts of hammer agent, 1-2 parts of thickener, 1-2 parts of dispersant, 3-5 parts of silver paste, 0.1-0.3 part of light absorber, 0.1-0.3 part of light stabilizer, 1-2 parts of color paste and 0.5-1 part of defoamer and a component B comprising 70-80 parts of isocyanate curing agent and 20-30 parts of cosolvent. During construction, a user only needs to mix the component A and the component B according to aweight ratio of 6-8:1. The hammer paint can be dried at normal temperature, is quick in drying and needless of heating for baking and can present needed hammer pattern three-dimensional effect after being sprayed; the hammer paint is convenient for construction and spraying, a paint film is hard while not crisp, high in plumpness, glossiness and hardness, excellent in resistance to corrosion and chemicals and weatherability, good in industrial application prospect and simple in preparation method and construction method and belongs to environment-friendly products.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based two-component acrylic hammer paint and a preparation method thereof. Background technique [0002] Hammer paint is a commonly used industrial art paint. It can form a layer of paint film similar to the hammer pattern left after the hammer hits the iron sheet on the surface of the painted object, so it is called hammer paint. It can not only cover the unevenness or other defects of the substrate, but also does not have the disadvantage of easy accumulation of dust and dirt in the wrinkles of wrinkled paint, and has an excellent protective and decorative effect. Its application field has been mainly used in the decoration of metal surfaces such as instruments, meters, hardware parts, medical equipment, metal filing cabinets, safes, and security doors. [0003] At present, with the steady growth of China's economy, the pressure on the environment is also increasing, ...

AI Technical Summary

Problems solved by technology

At present, water-based industrial paints have been successfully applied to construction machinery, baking varnishes, furniture paints and even automotive paints. However, in the field of hammer paint, the comprehensive performance of water-based paints is still difficult to meet the needs, such as poor construction performance of two components, pattern Not as beautiful as paint, poor hardness, poor gloss, poor weather resistance of paint film, etc.
