Embodiment 1
[0083] Primer formulation
[0084]
[0085] Topcoat formulation
[0086]
[0087] Thinner formulation
[0088]
[0089] The operation is as follows:
[0090] 1) Pretreatment: Pour the blank slider into the pretreatment automatic line for processing, and bake it in a baking machine through the degreasing and coating process to remove surface oil and roughen the surface of the slider.
[0091] 2) Add the above prepared primer paint and thinner to the spray gun according to the ratio of 1:0.8 for spraying, pour out the slider, spread out and air dry, bake (170°C for 30min), cool, and repeat 4 times;
[0092] 3) Add the topcoat paint and thinner to the spray gun in a ratio of 1:1 for spraying, pour out the slider, spread it out and air dry, bake (170°C for 30min), cool, and repeat 10 times.

Abstract
The invention provides a high-performance benzene-free cold spray paint, including a primer and a topcoat; the primer, in terms of mass content, consists of the following components: 40% to 80% of acrylic resin; 5% to 5% of amino resin 25%; epoxy resin 1% to 5%; isocyanate 1% to 5%; silanecoupling agent 1% to 3%; ethyl acetate 1% to 15%; Component composition: 40% to 80% of acrylic resin; 5% to 25% of amino resin; 1% to 15% of ethyl acetate; 1% to 15% of dimethyl carbonate; 1% to 15% of ethanol; 1% to ether 15%; leveling agent 0.3% ~ 1%; wetting agent 0.3% ~ 1%. In the present invention, by adjusting the formula of the top paint and adding a new formula primer process at the same time, it is used to combine the adjusted formula of the benzene-free top paint to achieve the purpose of not only having a strong bonding force after the slider is sprayed, but also having an environmentally friendly and pollution-free paint. .
Description
technical field [0001] The invention relates to the technical field of paints, in particular to a high-performance benzene-free cold spray paint and its application. Background technique [0002] Slider is an important part of clothing accessories. In order to make the overall appearance of clothing uniform, the shape and appearance of clothing accessories should be designed and produced in accordance with current fashion trends. In order to present a variety of sliders to meet the needs of the market, currently the sliders are mainly painted sliders, so the painted sliders have a large market demand. [0003] At present, most of the painting process of the slider adopts the cold spray process, which is sprayed at room temperature, then air-dried and baked, and the cycle is 8-10 times. The raw materials or additives of this kind of paint contain a certain amount of benzene homologues such as benzene and xylene. During the baking process, the benzene series will volatilize i...
