Problems solved by technology
In the prior art, there are many disadvantages in plastic products and their preparation methods, such as uneven spraying defects on the appearance of the product, pits and miscellaneous spots, thin coating, the highest surface hardness can only reach 1HB, and it is easy to cause scratches and dents. and paint falling off, the pass rate is low when preparing products, the extrusion and painting production lines are long, slow, and inefficient, and the surface layer is easy to be worn, which affects the appearance, etc.
In addition, a large amount of organic solvents volatilize during the spraying process, causing serious pollution to the environment and endangering the health of workers.
[0003] Therefore, the current plastic products and their preparation methods still need to be improved.

Abstract
The invention discloses a plastic product as well as a preparation method and a piece of refrigeration equipment thereof. The preparation method for the plastic product comprises the following steps that a plastic base stock and a surface layer base stock are molded in a co-extrusion way, so that the plastic base stock forms a body, and the surface layer base stock forms a surface layer, wherein the surfer layer is formed in at least a part of surface of the body. The plastic product is prepared by the method for preparing the plastic product, common formation of the body and the surface layer can be effectively realized, so that the technical problems of inconsistent product appearance, large color difference, low product percent of pass, low surface strength and easiness in scratches in the current preparation technology are solved successfully; and in addition, the preparation process is simple, the production cycle is short and the environment cannot be polluted.
Description
technical field [0001] The invention relates to a plastic product, a preparation method thereof, and a refrigeration device. Background technique [0002] Currently, plastic products have been widely used in almost every field. In the prior art, there are many disadvantages in plastic products and their preparation methods, such as uneven spraying defects on the appearance of the product, pits and miscellaneous spots, thin coating, the highest surface hardness can only reach 1HB, and it is easy to cause scratches and dents. And paint falling off, low pass rate when preparing products, long extrusion and painting production lines, slow speed, low efficiency, easy to wear the surface layer, affecting the appearance, etc. In addition, a large amount of organic solvents volatilize during the spraying process, causing serious pollution to the environment and endangering the health of workers. [0003] Therefore, current plastic products and their preparation methods still need ...
