Problems solved by technology

Traditional automotive interior high-gloss coatings need to be sprayed with a layer of primer first, and then a layer of varnish, for example: spray two coats of paint, that is, primer and top coat, and each coat must be baked at greater than 80°C after spraying Baking for more than 30 minutes, therefore, greatly increases the energy consumption and the discharge of harmful substances, which does not meet the requirements of environmental protection, energy saving and emission reduction

Embodiment 1

[0030] In Example 1, the effect of the amount of acrylic resin A and acrylic resin B on the performance of the coating was investigated, wherein the items that are usually tested by those skilled in the art, namely appearance, adhesion and bending test, were selected for evaluation.

[0031] A kind of high wear-resistant high-gloss coating for automobile interior decoration of present embodiment 1 is made by the raw material that comprises following parts by weight: 5 parts of wear-resistant additive A (NANOBYK-3650 of BYK company), wear-resistant additive B (Japan Gifu company ZF-24F) 2 parts, leveling agent (BYK306) 2 parts, UV absorber (Tinuvin400) 1 part, solvent (butyl acetate: trimethylbenzene: ethyl lactate = 3:3:2) 30 parts, diluted Agent (butyl acetate: trimethylbenzene: ethyl lactate = 3:3:2) 40 parts, wherein, acrylic resin A (DUROFTAL VPI 2803 / 78BAC of Solutia), acrylic resin B (Uracron CY472 of DSM E-57) and the amount of HDI curing agent (Bayer N3390) are shown i...

Embodiment 2

[0040] This embodiment 2 investigated the impact of the amount of wear-resistant additive A and wear-resistant additive B on the performance of the coating. Among them, the popular PV3975-2010 commonly used by those skilled in the art was selected to detect the abrasion resistance of the coating, and the gloss retention The rate is the evaluation index.

[0041] A kind of high wear-resisting high-gloss paint for automotive interior of present embodiment 2 comprises the raw material of following weight portion, acrylic resin A (DUROFTAL VPI 2803 / 78BAC of Solutia Company) 40 parts, acrylic resin B (DSM Company's) ( Make up 100 parts of the mixed solution obtained in step (1), 30 parts of HDI (N3390) curing agent, 40 parts of diluent (butyl acetate: trimethylbenzene: ethyl lactate = 3:3:2), among which, wear-resistant The amount of additive A (NANOBYK-3650 from BYK Company) and wear-resistant additive B (ZF-24F from Gifu, Japan) is shown in Table 2. The first group only added we...

Embodiment 3

[0047] Example 3 is divided into two groups, and this is used as an experimental group, and three parallel experiments are set for each group; in addition, a control group is also set, and three parallel experiments are also set for the control group. The experimental group is 17050270201-17050270206, and the control group is 17050270101-17050270106. Among them, 17050270101-03 and 17050270201-03 have been tested by Volkswagen PV3987-2016, and 17050270104-06 and 17050907-207-0204 have been tested by Volkswagen 0PV3.

[0048] The automotive interior paint of the control group is the product of Pater Chemical Industry (Shanghai) Co., Ltd. trade mark: P68934, and each raw material component and content, preparation method in the control group, the substrate sprayed and the spraying method are all the same.

[0049] Each raw material component and content, preparation method in the experimental group, the base material that is sprayed and spraying method are also all the same, see b...

Abstract

The invention discloses a high-wear-resistant and high-gloss coating for automobile interior trims, wherein the high-wear-resistant and high-gloss coating includes, in parts by weight, 30-50 parts ofacrylic resin A, 20-40 parts of acrylic resin B, 5-10 parts of a wear-resistant auxiliary agent A, 2-4 parts of a wear-resistant auxiliary agent B, 1-3 parts of a leveling agent, 1-2 parts of an ultraviolet absorbent, 10-40 parts of a solvent, 20-40 parts of an HDI curing agent and 10-40 parts of a diluent, wherein the hydroxyl value of the acrylic resin A accounts for 5.3-5.5% of the solid components, and the hydroxyl value of the acrylic resin B accounts for 1.6-1.8% of the solid components. The coating can be directly sprayed on engineering plastics ABS, PC / ABS and other substrates withoutfirst spraying of a primer, greatly reduces the use amount of organic solvents, and meets the requirements of energy saving and emission reduction; the formed coating layer has high glossiness, has extremely high mirror gloss and blackness and excellent adhesion force, weather resistance and other properties, especially has extremely high wear resistance, and has the wear resistance passing through Volkswagen PV3975-2010 and PV3987-2016 tests.

Description

technical field [0001] The invention belongs to the technical field of coatings for automotive interiors, and relates to a high-wear-resistant high-gloss coating for automotive interiors and a preparation method thereof. The high-wear-resistant high-gloss coating can be directly sprayed on substrates such as engineering plastics ABS, PC / ABS, etc. One-coat high-gloss solvent-borne coatings. Background technique [0002] In recent years, the automobile industry has developed rapidly in my country, and the per capita holdings have gradually increased. Traditional automotive interior high-gloss coatings need to be sprayed with a layer of primer first, and then a layer of varnish, for example: spray two coats of paint, that is, primer and top coat, and each coat must be baked at greater than 80°C after spraying Baking for more than 30 minutes, therefore, greatly increases energy consumption and discharge of harmful substances, and does not meet the requirements of environmental ...
