Paint composition applied to polyamide metal alloy toys

Abstract

The invention discloses a paint composition applied to polyamide metal alloy toys. The paint composition comprises the following components by weight percent: 20-40% of hydroxy acrylic resin, 20-30% of polyester resin, 10-20% of amino resin A, 10-20% of amino resin B, 2-4% of epoxy resin, 2-4% of organosilicon additive, 2-4% of adhesion promoter and 5-20% of pigments / dyes. The paint composition has the advantages of stable adhesion, easiness in drying, low cost and wide application range.

Description

technical field [0001] The invention relates to a paint technology for toys, in particular to a paint composition applied to polyamide metal alloy toys. Background technique [0002] China is the world's largest toy producer, and China produces more than 60% of the world's toy products. The two largest types of toy products are alloy toys and plastic toys. With the rise of labor costs in China, the profits of the toy industry are gradually declining. In order to achieve better development in the new form, toy companies cooperate with their raw material suppliers to develop a new type of material, polyamide The metal alloy replaces the original zinc alloy, which can effectively reduce the cost on the basis of ensuring the texture and performance of the zinc alloy. [0003] But, carry out the spraying of paint on the polyamide metal alloy substrate, adopt existing conventional paint product to have following problem: [0004] First, due to the poor surface activity of polya...

AI Technical Summary

Problems solved by technology

[0004] First, due to the poor surface activity of polyamide metal alloys compared with zinc alloys, existing coating products cannot form stable adhesion on polyamide metal alloys;

[0005] In addition, due to the slow thermal conductivity of polyamide metal alloys, existing coating products cannot achieve good drying without changing the production process
