preparation example Construction

[0025] The preparation method of the environmental protection sand pattern acrylic type weather-resistant powder coating comprises the following steps:

[0026] S1: Put matrix resin, pigments and fillers, curing agent, degassing agent, dispersant, sanding agent, toughening agent, brightening agent, wetting agent, preservative, antioxidant, light stabilizer into the mixing tank Mix for 4-6min to obtain a homogeneous mixture;

[0027] S2: Melt and extrude the homogeneous mixture prepared in step S1 through an extruder at 108-115° C., and pass through a tablet crushing machine to tablet, and obtain a tablet after cooling;

[0028] S3: cutting the flakes prepared in step S2 with a cutter to obtain pellets;

[0029] S4: crush the pellets prepared in step S3 and pass through a 60-300 mesh sieve to obtain an environmentally friendly sand texture acrylic weather-resistant powder coating.

Abstract

The invention discloses an environment-friendly sand streak acrylic acid type weather-proof powder coating. The environment-friendly sand streak acrylic acid type weather-proof powder coating is prepared from, by weight, 120-180 parts of matrix resin, 60-100 parts of pigments, 30-50 parts of a curing agent, 6-9 parts of a degassing agent, 2-4 parts of a dispersing agent, 0.6-1.2 parts of a sand streak agent, 0.4-0.6 part of a toughening agent, 0.4-0.5 part of an optical brightener, 0.3-0.5 part of a wetting agent, 0.2-0.5 part of a corrosion remover, 0.2-0.4 part of an antioxidant and 0.2-0.4 part of a light stabilizer. The environment-friendly sand streak acrylic acid type weather-proof powder coating is obtained through raw material mixing, melting, tabletting, pelletizing and smashing. The environment-friendly sand streak acrylic acid type weather-proof powder coating has high bending resistance, high impact resistance high adhesive force and other performances, and can meet the requirement of people for a sand streak type coating with the frosted hand heeling.

Description

【Technical field】 [0001] The invention belongs to the technical field of paint preparation, and in particular relates to an environment-friendly sand pattern acrylic type weather-resistant powder paint. 【Background technique】 [0002] With the rapid development of my country's economy and the improvement of people's living standards, people's demand for the quality and variety of designs and colors involved in daily life is getting higher and higher. Iron and aluminum doors and windows have patterns and colors that simulate nature (such as wood pattern, marble pattern, etc.) thermal transfer technology, which enriches our life color, and has fireproof effect, but there are also certain problems, mainly: (1) the current production process is mainly to first make the product (Doors and windows, etc.) are processed and shaped, then coated with powder coating, and then manually coated with glue on the product, sticky transfer paper, heat transfer, the production efficiency is low,...
