AI Technical Summary

Problems solved by technology

The boiling point of cyclopentane is relatively low. According to the current equipment status of refrigerator manufacturers, cyclopentane cannot be used in existing equipment, and HCFC141b approved by international environmental protection organizations is used to replace Freon. The lining plastic material (HIPS-ABS) has a strong chemical corrosion effect, so the selection of refrigerator plastic materials has become a topic in the refrigerator manufacturing industry today.

Abstract

A covering resin material resisting 141 b PE / PS used as the liner of refrigerator is prepared from polystyrene, polyethene, acrylic acid, derivative, peroxide, promoter, toughening agent, polyethene wax, zinc stearate, and antioxidizing agent.

Description

technical field [0001] The invention belongs to a resin for making refrigerator lining and anti-chemical corrosion. Background technique [0002] The traditional refrigerator manufacturing industry uses freon (CFC) refrigerants. After freon accumulates in the high altitude of the atmosphere, it undergoes a series of photochemical degradation reactions to generate chlorine free radicals and destroy the high-altitude ozone layer, that is, the so-called "black hole" that destroys the environment in which human beings live. Therefore, international environmental protection organizations cancel the application of Freon refrigerants and use cyclopentane (C5) instead of Freon. The boiling point of cyclopentane is relatively low. According to the current equipment status of refrigerator manufacturers, cyclopentane cannot be used in existing equipment, and HCFC141b approved by international environmental protection organizations is used to replace Freon. The plastic material (HIPS-A...
