Embodiment 1

[0029] Add 100g of butyl acrylate (BA), 20g of hydroxyethyl methacrylate (HEMA), 10g of methacrylic acid (MAA), 60g of diacetone alcohol and 60g of n-butanol into the container, and stir at 95-100°C for 5min. Dissolve 2 g of benzoyl peroxide in 30 g of diacetone alcohol, slowly add the dibenzoyl peroxide diacetone alcohol solution dropwise into a reaction container, stir and react at 95-100° C. for 3 hours, and obtain an acrylate resin.

[0030] Dissolve 30g of epoxy resin and 35g of amino resin in a mixed solution of 40g of diacetone alcohol and 20g of n-butanol, slowly add to 120g of the above-mentioned synthesized acrylate resin, stir and mix for 1 hour at 85-90°C, adjust with 25ml of distilled water Paint viscosity and solid content, to obtain water-based paint.

Embodiment 2

[0032] Add 100g of butyl acrylate (BA), 20g of hydroxyethyl methacrylate (HEMA), 10g of methacrylic acid (MAA), 60g of diacetone alcohol and 60g of n-butanol into the container, and stir at 95-100°C for 5min. Dissolve 2 g of benzoyl peroxide in 30 g of diacetone alcohol, slowly add the dibenzoyl peroxide diacetone alcohol solution dropwise into the reaction vessel, stir and react at 95-100° C. for 3 hours to obtain an acrylate resin.

[0033] Dissolve 20g of epoxy resin and 25g of amino resin in a mixed solution of 30g of diacetone alcohol and 15g of n-butanol, slowly add to 120g of the acrylate resin synthesized above, stir and mix for 1 hour at 85-90°C, adjust with 22ml of distilled water Paint viscosity and solid content, to obtain water-based paint.

Embodiment 3

[0035] Add 100g of butyl acrylate (BA), 20g of hydroxyethyl methacrylate (HEMA), 10g of methacrylic acid (MAA), 60g of diacetone alcohol and 60g of n-butanol into the container, and stir at 95-100°C for 5min. Dissolve 2 g of benzoyl peroxide in 30 g of diacetone alcohol, slowly drop the dibenzoyl peroxide diacetone alcohol solution into a reaction vessel, stir and react at 95-100°C for 3 hours, and obtain an acrylate resin.

[0036]Dissolve 15g of epoxy resin and 20g of amino resin in a mixed solution of 20g of diacetone alcohol and 10g of n-butanol, slowly add to 120g of the above-mentioned synthesized acrylate resin, stir and mix for 1 hour at 85-90°C, adjust with 18ml of distilled water Paint viscosity and solid content, to obtain water-based paint.

Abstract

The invention discloses water-based vehicle lamp reflecting cover film-coating paint and a preparation method thereof, relating to vacuum film-coating paint. The paint consists of the following components in percentage by mass: 100 percent of acrylate resin, 15-30 percent of epoxy resin and 20-35 percent of amino resin, wherein the acrylate resin consists of the following components in percentage by mass: 100 percent of butyl acrylate, 18-22 percent of hydroxyethyl methylacrylate and 8-12 percent of methacrylic acid. The preparation method comprises the following steps: adding the butyl acrylate, the hydroxyethyl methylacrylate and the methacrylic acid into a container, adding a mixed solvent of diacetone alcohol and n-butyl alcohol, stirring at 95-105 DEG C, dissolving benzoyl peroxide in a diacetone alcohol solvent, adding a benzoyl peroxide-diacetone alcohol solution, and reacting to obtain an acrylate resin solution; adding the epoxy resin and the amino resin into the mixed solvent of diacetone alcohol and n-butyl alcohol, adding an obtained epoxy resin-amino resin solution into the acrylate resin solution, reacting to obtain solvent type paint, and adding distilled water to obtain a product.

Description

technical field [0001] The invention relates to a vacuum coating coating, in particular to a water-based coating coating for a reflector of a car lamp with an acrylic ester resin as the main body and a preparation method thereof. Background technique [0002] With the substantial improvement of people's economic living standards, the use of automobiles is increasing at an alarming rate, and the market demand for automobile lamp reflectors is also increasing. The bulk molding compound used in the reflector of automobile lights has a rough surface without electroplating. In order to achieve a good reflective light effect, it is necessary to electroplate a metal aluminum layer on the surface to make the surface smooth. The surface of the plated part is therefore Can have high metallic luster and mirror effect. Since the bulk molding compound is molded into a car lamp reflector, the surface of the product is rough and contains volatile impurities. If it is directly electroplate...
