Embodiment 1

[0023] A preparation method of ultra-wearable plastic paint, the method includes the following process steps:

[0024] (1) Preparation:

[0025]

[0026] Put the resin into the tank first according to the weight ratio of the appeal, then put the solvent, add the additives while stirring, and finally stir at high speed for 15 minutes.

Embodiment 2

[0031] A preparation method of ultra-wearable plastic paint, the method includes the following process steps:

[0032]

[0033] Put the resin into the tank first according to the weight ratio of the appeal, then put the solvent, add the additives while stirring, and finally stir at high speed for 15 minutes.

Embodiment 3

[0038] A preparation method of ultra-wearable plastic paint, the method includes the following process steps:

[0039]

[0040] Put the resin into the tank first according to the weight ratio of the appeal, then put the solvent, add the additives while stirring, and finally stir at high speed for 15 minutes.

[0041] Appeal Example Plastic Paint Performance Results

[0042]

[0043]

[0044] The performance results of the above three examples are all very good, especially Example 3, the hardness reached 2H. This is because high-hydroxy acrylic acid (hydroxyl value: about 100) and low-hydroxy acrylic acid (hydroxyl value: about 60) are mixed, and then modified with polyester to make it have better wear resistance and Weather resistance. Because the content of polyester hydroxyl active functional groups is higher than that of acrylic acid, the crosslinking density is greatly improved. On the other hand, polyester is a branched hydroxyl resin with high active group content, high polar...

Abstract

The invention relates to an abrasion-resistant plastic coating and a preparation method thereof. The abrasion-resistant plastic coating is prepared from the following components in parts by weight: 5-10 parts of silver powder, 40-50 parts of a resin A, 10-16 parts of a resin B, 0.2-1 part of a dispersing agent, 0.5-2 parts of a flatting agent, 3-5 parts of wax powder 1778, 2-10 parts of wax liquor and 15-30 parts of a mixed solvent. The preparation method of the abrasion-resistant plastic coating comprises the following steps of: preparing raw materials according to a formula, dissolving the silver powder in the mixed solvent, adding other components, stirring at a low speed, and stirring at a high speed for 15 minutes to obtain the abrasion-resistant plastic coating. Compared with the prior art, the abrasion-resistant plastic coating provided by the invention has the advantages of good abrasion, scraping and weather resistance due to the combination of the special resins and the application of the special additives and the special solvent.

Description

Technical field [0001] The invention relates to a paint, in particular to a wear-resistant plastic paint and a preparation method thereof. Background technique [0002] At present, with the improvement of people's material level, the requirements for abrasion resistance and weather resistance of the exterior decoration effect of automobiles are also getting higher and higher. Acrylic resin plastic paint alone has shortcomings in these aspects. Chinese patent CN101643624A discloses a UV-curable high wear-resistant matte paint and its preparation method, including the following components by weight percentage: primer includes hydroxy acrylic resin 55-60; 20% cellulose acetate butyrate resin soluble 10- 13; methyl isobutyl ketone 4-6; leveling agent 0.1-0.2; aluminum silver paste 5-7; ethyl acetate 17-19; curing agent includes hexamethylene diisohydrogen ester 55-60; unsaturated Aliphatic polyurethane acrylate 10-15; butyl acetate 26-32, which can be applied under ordinary coating ...
