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

Embodiment Construction

[0037] The following description will be made with reference to preferred embodiments of the present invention.

[0038] The embodiment of the present invention provides a kind of baking varnish that is used for polyamide metal alloy toy, comprises following component by weight ratio:

[0039] Hydroxy acrylic resin: 20-40%

[0040] Polyester resin: 20-30%

[0041] Amino resin A: 10-20%

[0042] Amino resin B: 10-20%

[0043] Epoxy resin: 2-4%

[0044] Silicone additives: 2 to 4%

[0045] Adhesion promoter: 2~4%

[0046] Pigment / dye: 5~20%.

[0047] Describe below the effect of each component in the formula among the present invention:

[0048] Among them, hydroxyacrylic resin is characterized by fast drying and wide adhesion. After the screening of acrylic acid commonly used in coatings, this resin has good adhesion, gloss, haze and fullness on polyamide metal alloys, and the price is moderate. It is suitable as a raw material for polyamide metal alloy toy coatings, th...

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...
