Plastic special for refrigerator inner plate and preparation method of plastic

Abstract

The invention discloses a plastic special for a refrigerator inner plate, and relates to the technical field of plastic products. The plastic is prepared from the following raw materials in parts by weight: 80-90 parts of polypropylene, 50-60 parts of EPDM rubber, 20-30 parts of high density polyethylene, 8-10 parts of a nucleating agent, 4-6 parts of an anti-oxidant, 20-30 parts of calcium stearate, 25-35 parts of epoxidized soybean oil, 30-40 parts of a filling material and 100-120 parts of deionized water. The plastic has the benefits that the process flow is concise, the raw material ratio is reasonable, and the plastic is produced by adopting chemical substances which are all nontoxic and harmless. The prepared plastic special for the refrigerator inner plate is good in use effect, has the functions of low temperature resistance and corrosion resistance, and is obvious in use effect, pollution-free, high in market value and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to a special plastic for refrigerator inner panels and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or few addi...

Problems solved by technology

The so-called plastic is actually a kind of synthetic resin. Its shape is similar to pine resin in natural resins, but it is called plastic because it is artificially synthesized by chemical means. Refrigerators are one of the indispensable electrical appliances in every household. However, as we all know, many structures on the refrigerator are made of plastic, but because the temperature in the refrigerator is low all the year round, and the humidity is also high, if the internal plastic is replaced by ordinary plastic, its service life will be very short and durable. The problem of weak low temperature and poor water resistance will undoubtedly be revealed, and the food that people eat directly is often stored in the refrigerator. If the plastic is produced, it contains toxic chemical raw materials, which is easy to cause personal injury
