A kind of preparation method of plain colored high-gloss shell of green home appliances

Abstract

The invention discloses a method for preparing a plain high-gloss shell of a green home appliance. The invention comprises the following technical steps: co-extruding recycled plastics and flame-retardant plastics into boards; using a special surface non-contact gas pressure forming machine to form; The semi-finished green home appliance shell is cut in three dimensions; according to the size requirements of the cut shell semi-finished product, the insert is injected; the green home appliance shell semi-finished product after forming and cut is assembled with the injection molded insert; the assembly is performed using an ultrasonic welding machine After welding the inserts; apply glue to the above welded inserts. Adopting the present invention not only satisfies the requirement of high-gloss flame-retardant properties of green home appliances, but also improves the reutilization rate of industrial waste and reduces environmental pollution; the production process is simple and fast, reducing equipment investment; the produced products are plain, reducing the painting process and meeting environmental protection requirements .

Description

technical field [0001] The invention relates to the technical field of home appliance shell manufacturing, in particular to a preparation method for a green home appliance plain high-gloss shell. Background technique [0002] At present, the packaging shapes of various home appliances in the domestic and international markets are constantly being innovated, such as air conditioners, flat-screen TVs, refrigerators and other industries. Their appearance and shape tend to be three-dimensional and streamlined. material.

At the same time, due to the rapid replacement of household appliances, a large amount of industrial waste is accumulated. How to recycle old household appliances is a difficult problem to solve

[0003] Advanced countries have put forward environmental protection requirements, and a considerable proportion of recycled materials must be used in the production of home appliances, which greatly increases the difficulty of the injection molding industry, and the materials used in these products and product design mainly consider their processing performance, and do not consider appearance and further environmental protection
