Anti-sunshine machine protection cover plastic and preparation method thereof

Abstract

The invention discloses anti-sunshine machine protection cover plastic. The plastic is prepared from, by weight, 0.1-0.2 part of ultraviolet absorber UV-329, 1-2 parts of benzotriazole, 140-200 parts of high density polyethylene, 2-3 parts of didecyl dimethyl ammonium bromide, 1-2 parts of citrus residues, 0.6-1 part of aluminum ammonium sulfate, 3-4 parts of phytic acid, 10-12 parts of polybutylene terephthalate, 4-5 parts of tackifier, 10-14 parts of illite powder, 2-3 parts of oyster shell powder and 1-2 parts of sodium dodecyl sulfate. The ultraviolet absorber UV-329, the benzotriazole and the like are added into the plastic, so the anti-ultraviolet intensity of the plastic can be obviously improved, and the anti-sunshine performance is improved. The plastic is particularly suitable for an external-use machine protection cover and good in heat resistance, water resistance and acid-base resistance. Pentaerythritol and polyvinylpyrrolidone are used as main materials of the tackifier added into the plastic, so that dispersity of filler in the plastic is effectively improved, and stability and strength of a finished plastic product are improved.

Description

Technical field [0001] The invention relates to the technical field of plastics, in particular to a mechanical anti-sun protection cover plastic and a preparation method thereof. Background technique [0002] Plastic is a polymer compound that is polymerized by monomer as raw material through addition polymerization or polycondensation reaction. It is commonly known as plastic or resin. The composition and shape can be changed freely. It is composed of synthetic resin and fillers, plasticizers, stabilizers, and lubricants. , Pigments and other additives, most plastics are light in weight, chemically stable, and will not rust; good impact resistance; have good transparency and wear resistance; good insulation, low thermal conductivity; general moldability, Good colorability and low processing cost; but current plastic products also have many common shortcomings: most plastics have poor heat resistance, large thermal expansion, and easy to burn; poor dimensional stability and easy ...

[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. Composed of additives such as pigments and pigments, most plastics are light in weight, chemically stable, and will not rust; they have good impact resistance; they have good transparency and wear resistance; they have good insulation and low thermal conductivity; general formability, Good colorability and low processing cost; however, there are many common shortcomings in plastic products at present: most plastics have poor heat resistance, high thermal expansion rate, and are easy to burn; poor dimensional stability and easy deformation; Brittle and easy to age; the different properties of plastics determine its use in life and industry. With the advancement of technology, research on plastic modification has never stopped
