preparation example Construction

[0034] The invention provides a kind of preparation method of spray paint slider, comprises the following steps:

[0035] Step 1) Phosphating the rough slider, drying, drying, and roughening to obtain a pretreated slider;

[0036] 2) adopt the environment-friendly water-based cold spray paint described in the above technical scheme to spray on the surface of the pretreatment slider, air-dry, bake, and cool;

[0037] 3) Repeat step 2) 8 to 10 times to obtain a painted slider.

[0038] In the invention, the rough slider is treated with phosphating, spin-dried, and roughened. Specifically, the present invention pours the blank slider into the pre-treatment automatic line for processing, and bakes it in a baking machine through degreasing and coating processes to remove surface oil and roughen the surface of the slider.

[0039] After the pretreatment slider is obtained, the present invention adopts the environmental-friendly water-based cold spray paint described in the above t...

Abstract

The invention provides an environment-friendly waterborne cold spray paint and an application thereof. The waterborne cold spray paint comprises the following components in percent by mass: 40-70% ofacrylic resin, 5-25% of Cytec amino resin, 5-20% of toner, 5-40% of water, 0.3-1% of a leveling agent, 0.3-1% of a wetting agent, and 0.3-1% of a waterborne dispersing agent. Compared with an oily paint, the provided spray paint is a waterborne paint, does not contain an organic solvent, and has less harm to the human body, a working environment of staff is improved, and the safe and green manufacturing is realized; and the water-washing strength of the waterborne cold spray paint after being sprayed on a slider is relatively high. The waterborne cold spray paint meets OEKO requirements; volatile components such as xylene, ethyl acetate and formaldehyde are not detected; and a water-washing grade is grade 4.

Description

technical field [0001] The invention belongs to the technical field of water-based paint, in particular to an environment-friendly water-based cold spray paint and its application. Background technique [0002] Sliders are an important part of clothing accessories. For the uniformity of the overall appearance of clothing, the shape and appearance of clothing accessories are also 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, the market begins to use the cold spray process (spray at room temperature, air dry, bake, cycle 8-10 times). The raw materials or additives of this kind of paint contain a certain amount of benzene, xylene or other organic solvents. Some of the oily solvents will volatilize, resulting in a poor working environment. Contents of the invention...
