Preparation method for plastic base of refrigerator

Abstract

The invention discloses a preparation method for a plastic base of a refrigerator. The preparation method comprises the following steps: heating and plasticizing polycarbonate, an ethylene-vinyl acetate copolymer and an acrylonitrile-butadiene-styrene copolymer so as to obtain a first material; adding disproportionated rosin and polyethylene wax into the first material, carrying out plasticization, adding diatomite, talcum powder, aluminum hydroxide, calcium sulfate whiskers, a silane coupling agent, carbon fibers, acetic anhydride, stearyl alcohol, 1,1-bis-(tert-amylperoxy)cyclohexane and an accelerator TMTM and carrying out plasticization so as to obtain a second material; and subjecting the second material to heating and plasticizing, thin-passing, and sheet production successively so as to obtain the plastic base of the refrigerator. The plastic base of the refrigerator prepared in the invention has good resistance to permanent compression deformation, good toughness and excellent resistance to impact and tearing, reduces the damage of the refrigerator to floors, and can ensure safe use of the refrigerator for at least 20 years.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a method for preparing a refrigerator plastic base. Background technique [0002] Because the refrigerator has remarkable food preservation and cold storage functions, it has entered the lives of millions of households as a commonly used household appliance. The box structure of the refrigerator is mainly composed of an outer box, an inner liner, a box door, and a heat-insulating foam layer, etc., and the outer box is generally composed of a U shell, a back panel and a refrigerator base, and the compressor and other key components are fixed on the refrigerator base , the structure is more complex. The bottom of the refrigerator is generally made of plastic material. It is necessary to install the bottom plate of the press on the plastic base first, and then install the plastic base on the bottom of the refrigerator. The current plastic base has problems of resistance to permane...

AI Technical Summary

Problems solved by technology

The box structure of the refrigerator is mainly composed of an outer box, an inner tank, a box door, and a heat-insulating foam layer, etc., and the outer box is generally composed of a U shell, a back plate and a refrigerator base, on which key components such as a compressor are fixed. , the structure is more complex

The bottom of the refrigerator is generally made of plastic material. It is necessary to install the bottom plate of the press on the plastic base first, and then install the plastic base on the bottom of the refrigerator. The current plastic base has problems of resistance to permanent compression deformation and insufficient toughness, which need to be solved urgently
