Abstract
The invention provides a low-temperature-resistant pressure-resistant plastic material which comprises the following raw materials in percentage by weight: 30-60 percent of polyethylene, 25-40 percent of polyethylene glycol terephthalate, 10-20 percent of polycarbonate, 10-15 percent of a compatilizer, 1-10 percent of a cold-resistant plasticizer, 1-5 percent of zinc oxide, 0.5-3 percent of a flexibilizer and 0.1-1 percent of an antioxidant. The material is good in low temperature resistance, still has good toughness at very low temperature, and has good physical and mechanical properties, pressure resistance, impact resistance and flowability, the characteristics of an original plastic material are ensured, the application range of environment temperature is expanded, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of plastic material, be specially a kind of low temperature resistant pressure-resistant plastic material.
Background technology
Plastic prod has become a kind of requisite daily necessities in daily life, is seen everywhere in production, life.Relative to metal, stone material, timber, plastics have the advantages such as cost is low, plasticity-is strong, be widely used in national economy, plastics industry occupies very consequence in the world today, and the production of plastics is in high speed development all over the world for many years.The performances such as the poor conductor of the chemical stability that the such as quality represented due to plastics self is light, excellent and electrical insulating property and heat, make the Application Areas of plastics and region more and more wide in range.
At present, at low ambient temperatures, resistance to impact shock is poor for plastic material, easy brittle rupture.The index weighing plastics lower temperature resistance is embrittlement temperature, and when lower than embrittlement temperature, plastic material is brittle rupture, and impact value significantly declines.Therefore, envrionment temperature directly limit the use range of plastics, how to improve the low temperature resistant crushing resistance of plastics, thus improves the use range of plastic material.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of resistance to low temperature excellent, crushing resistance is strong, the low temperature resistant pressure-resistant plastic material of long service life.
The present invention is achieved through the following technical solutions:
A kind of low temperature resistant pressure-resistant plastic material, comprises the raw material composition of following weight percent: polyethylene 30 ~ 60%, polyethylene terephthalate 25 ~ 40%, polycarbonate 10 ~ 20%, compatilizer 10 ~ 15%, cold resistant plasticizer 1 ~ 10%, zinc oxide 1 ~ 5%, toughner 0.5 ~ 3%, oxidation inhibitor 0.1 ~ 1%.
Further, described compatilizer is maleic anhydride.
Further, described cold resistant plasticizer is dihexyl sebacate.
Further, described toughner is chlorinatedpolyethylene.
Further, described oxidation inhibitor is 2,6-, tri-grades of butyl-4-methylphenols or pentaerythritol ester.
The invention has the beneficial effects as follows: material provided by the invention has excellent lower temperature resistance, still good toughness can be showed under extremely low temperature, there is good physical and mechanical properties simultaneously, crushing resistance, impact and mobility, and ensure that the characteristic of original plastic material, add the use range of envrionment temperature, improve work-ing life.
