Problems solved by technology

The most noble and beautiful is the realistic electroplating effect made by using electroplating silver paste, but the price of electroplating silver paste is extremely expensive, which limits its wide application, and the electroplating silver plastic paint made of electroplating silver paste needs to be sprayed with a black base first. paint; even if the imitation electroplated aluminum silver paste is used, the cost is very high and the application is also limited

Embodiment 1

[0064] Prepare the plastic paint main paint of imitation electroplating effect of the present invention:

[0065] According to the weight shown in Example 1 in Table 1, each component is taken, and the preparation method is as follows:

[0066] Step 1: Pre-dispersion of aluminum-silver paste: Mix aluminum-silver paste, toluene and dispersant, stir at a low speed until there are no aggregated aluminum powder particles, and set aside;

[0067] Step 2: Mix 50% acrylic resin, 20% cellulose acetate butyrate, and 30% vinyl acetate resin evenly, then add anti-settling agent, stir and disperse at high speed for 15 minutes, then add leveling agent, ethyl acetate by weight ester, methyl isobutyl ketone, isobutanol and ethylene glycol monobutyl ether, stir well;

[0068] Step 3: Add the aluminum-silver paste pre-dispersed in the above step 1 to the paint obtained in step 2 under low-speed stirring, and continue to stir at a low speed for 10-15 minutes until the dispersion is uniform, an...

Embodiment 2

[0079] With each component weight of embodiment 2 specified in table 1, repeat the method described in embodiment 1 (only each component weight changes) prepare the plastic paint master paint that obtains imitation electroplating effect; Repeat the group of thinner in embodiment 1 Divide, proportioning and preparation method prepare diluent; Main paint and diluent are mixed according to weight ratio 1: 2.5, spray then, obtain paint film after drying with the method described in embodiment 1, performance test result (film thickness 15 -20 μm) as shown in the corresponding data of Example 2 in Table 2.

Embodiment 3

[0081] With each component weight of embodiment 2 specified in table 1, repeat the method described in embodiment 1 (only each component weight changes) prepare the plastic paint master paint that obtains imitation electroplating effect; Repeat the group of thinner in embodiment 1 Divide, proportioning and preparation method prepare diluent; Main paint and diluent are mixed according to weight ratio 1: 2.0, spray then, obtain paint film after drying with the method described in embodiment 1, performance testing result (film thickness 15 -20 μm) as shown in the corresponding data of Example 3 in Table 2.

Abstract

The invention discloses a plastic paint with simulated electroplating effect. The composition and the weight ratio of the invention are as follows: 30 to 45 of acrylic resin with 50 percent of solid content and 70 to 90 DEG C of Tg, 20 to 30 of cellulose acetate butyrate with 20 percent of solid content, 8 to 12 of triad copolymer vinyl chloride-acetate resin with 30 percent of solid content, 6 to 10 of non-floating aluminum and silver pulp with an average diameter less than or equal to 20 Mum, 0.3 to 0.5 of dispersant, 0.2 to 0.4 of flatting agent, 0.4 to 0.6 anti-settling agent, 6.0 to 10.0 of toluene, 3.5 to 6.0 of ethyl acetate, 3.5 to 6.0 methy isobutyl ketone, 3.0 to 5.0 of isobutanol and 4.0 to 7.0 of glycol butyl ether. The special diluent of the invention, according to the weight ratio, is made from the following components evenly mixed: 20 of white gas, 10 of toluene, 22 of ethyl acetate, 15 of acetone, 25 of isobutanol and 8 of glycol butyl ether. The main paint which comprises the composition and the diluent are evenly mixed according to the ratio of 1: 2-3, then the mixture is used for spray coating; the metallic appearance of the paint film obtained is very close to the effect of the electroplating, and the paint film has good alcohol resistance with high hardness and strong wear resistance, and also has simple process. The aluminum and silver pulp used is a common type, the cost of which is only 5 percent to 10 percent of the simulated electroplating aluminum and silver pulp and about 2 percent of electrosilvering.

Description

technical field [0001] The invention relates to a plastic paint, in particular to an acrylic plastic paint with an imitation electroplating effect and a preparation method thereof. The invention also relates to a special diluent for the plastic paint and a use method. Background technique [0002] The surface protection and decoration of plastic shells of electronic and electrical products, plastic toys, auto parts and other plastic products generally adopt acrylic plastic paint, among which aluminum powder paint is the most widely used, and different aluminum silver pastes are selected, and the paint film can achieve different metal effects , so as to meet different aesthetic needs and achieve personalized decoration effects. The most noble and beautiful is the realistic electroplating effect made by using electroplating silver paste, but the price of electroplating silver paste is extremely expensive, which limits its wide application, and the electroplating silver plastic...
