Problems solved by technology

[0003] The strength of the reinforcement board inside the refrigerator is low, and it is easily affected by chemical and physical factors, which makes the product oxidative and degraded, resulting in brittleness of the product, which seriously affects the service life and performance of the product. Therefore, we propose a reinforcement board for refrigerators and its manufacturing process

Abstract

The invention discloses a reinforcing plate for a refrigerator and a manufacturing process thereof, which relate to the field of refrigerators, and provide the following scheme aiming at the problems of low strength and poor oxidation resistance of the traditional reinforcing plate for the refrigerator: the reinforcing plate comprises the following raw materials in parts by weight: 50-60 parts of polyurethane plastic, 10-12 parts of isocyanate, 8-10 parts of glass fiber, 7-9 parts of titanium dioxide, 7-9 parts of synthetic vegetable fatty acid ester, 5-7 parts of zinc stearate, 4-6 parts of carvacrol, 4-6 parts of phosphite ester and 4-6 parts of lignite wax. The glass fiber and the titanium dioxide are added into the polyurethane plastic and the isocyanate, the overall strength of the product can be effectively improved, the zinc stearate metal soap stabilizer is added, plastic damage and further degradation caused by thermal action can be delayed or avoided, and the service life of the product is prolonged; meanwhile, a main antioxidant carnitol and a secondary antioxidant phosphite ester are sequentially added, so that oxidative degradation of the plastic is delayed, product embrittlement and color change are prevented, the service life of the product is prolonged, and the performance of the product is improved.

Description

Technical field [0001] The present invention relates to the field of refrigerators, and more particularly to a reinforcing plate for refrigerator and a manufacturing process thereof. Background technique [0002] The refrigerator is a refrigeration apparatus that maintains a constant low temperature, and is also a civilian product that keeps food or other items constant low temperature cold. There is compressor in the box, the ice machine is used to frozen cabinets or boxes with a storage box with a refrigeration device. The volume of the household refrigerator is usually 20 ~ 500 liters. In 1910, the world's first compressed refrigeration household refrigerator came in the United States. In 1925, Sweddi has developed a household absorption refrigerator. In 1927, US General Electric Co., Ltd. developed a fully enclosed refrigerator. In 1930, air cooling continuous diffusion absorption refrigerators in different heating methods were placed in the market. In 1931, the new refrigera...
