preparation example Construction

[0046] The preparation method of described sand pattern type weather-resistant powder coating, comprises the following steps:

[0047] 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;

[0048] S2: melt and extrude the homogeneous mixture prepared in step S1 through an extruder at 118-115° C., and pass through a tablet crushing machine to tablet, and obtain a tablet after cooling;

[0049] S3: cutting the flakes prepared in step S2 with a cutter to obtain pellets;

[0050] S4: crush the pellets prepared in step S3 and pass through a 60-300 mesh sieve to obtain a sand textured weather-resistant powder coating.

Abstract

The invention discloses a sand-textured weather-resistant powder coating and a preparation method thereof. The sand-textured weather-resistant powder coating comprises the following raw materials in parts by weight: 65 to 80 parts of matrix resin, 25 to 40 parts of a pigment filler, 4 to 6 parts of a curing agent, 0.4 to 0.6 part of a degassing agent, 2 to 4 parts of a dispersant, 0.2 to 0.4 part of a sand texturing agent, 0.4 to 0.6 part of a toughening agent, 0.4 to 0.5 part of a gloss enhancer, 0.3 to 0.5 part of a wetting agent, 0.2 to 0.5 part of a preservative, 0.2 to 0.4 part of an antioxidant and 0.2 to 0.4 part of a light stabilizer. The sand-textured weather-resistant powder coating is prepared by raw material mixing, melting, sheeting, granulation and crushing. The sand-textured weather-resistant powder coating does not contain any harmful heavy metal, and is an environment-friendly powder coating with the performance of higher bending resistance, impact resistance, adhesion and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a sand pattern weather-resistant powder paint and a preparation method thereof. 【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, i...
