Problems solved by technology

[0003] 1. Some resins have good matting properties, but poor fullness and transparency of the paint film
[0004] 2. Some resin paint films have good fullness and transparency, but poor matting properties
Therefore most of the matte alkyds do not have good fullness
In order to improve the fullness of the paint film, the matting property of the paint film is sacrificed. Therefore, in order to achieve the required gloss when making paint, the amount of matte powder will be increased, which not only increases the cost, but also deteriorates the transparency of the paint film, because The transparency of the paint film decreases when more matte powder is added

Abstract

The invention discloses a matt alkyd resin and a preparation method thereof. The matt alkyd resin is prepared by the following components: 10-15 parts of short-chain fatty acid, 8-14 parts of octadecanoic alkene vegetable oil acid, 10-15 parts of mono-pentaerythritol, 25-30 parts of phthalic anhydride, 1-5 parts of glycerol, 5-10 parts of divalent alcohol, 0.05-0.2 part of color subtraction agent, 3-6 parts of dimethyl benzene, 20-25 parts of diluted aromatic solvent and 4-8 parts of diluted low-boiling-point esters solvent. According to the matt alkyd resin provided by the invention, the components and mixture ratios of all raw materials are screened through lots of experiments so as to prepare and obtain the matt alkyd resin with appropriate molecular weight, and the matt alkyd resin has the advantages of excellent matting property, good transparency and fullness and wide application range. The preparation method of the matt alkyd resin has the advantages of reasonable process design, high preparation efficiency, low energy consumption and easiness in implementation, the whole preparation technology has strong operability and the matt alkyd resin prepared by adopting the preparation method has excellent performances.

Description

technical field [0001] The invention relates to a resin, in particular to a matte alkyd resin and a preparation method thereof. Background technique [0002] Matte alkyd resin is mainly used for matte polyester paint for home decoration, and the market demand is very large. In the paint making process, matt powder is mainly added to the matte resin to achieve matting, but the matte produced by different matte alkyd resins Varnish properties vary. To evaluate the quality of matt resin, it mainly reflects the matting property (that is, the gloss after being made into a paint), transparency, and fullness. The matte alkyd resins currently on the market for matte polyester paints have the following problems: [0003] 1. Some resins have good matting properties, but poor fullness and transparency of the paint film. [0004] 2. Some resin paint films have good fullness and transparency, but poor matting properties. [0005] Because most of the matte alkyd resins currently on th...
