Description
Technical field
The present invention relates to a kind of plastic material, specially a kind of low temperature resistant pressure-resistant plastic material.
Background technology
Plastic product has become a kind of essential daily necessities in daily life, in production, life
It is seen everywhere in work.Relative to metal, stone material, timber, plastic products have many advantages, such as that at low cost, plasticity is strong, are passed through in its people
It is widely used in Ji, plastics industry occupies particularly important status in today's world, and the production of plastic products is alive for many years
Boundary various regions are developed at high speed.Such as light weight, excellent chemical stability and the electrical insulating property that are showed by plastics itself and
The performances such as the non-conductor of heat, keep the application field of plastics and region more and more wide in range.
Currently, plastic material is at low ambient temperatures, impact strength is poor, is easy brittle fracture.It is low temperature resistant to weigh plastics
Property index be brittle temperature, when less than brittle temperature, plastic material be in brittle fracture, and impact value significantly under
Drop.Therefore, environment temperature directly limits the use scope of plastics, how to improve the low temperature resistant crushing resistance of plastics, so as to improve
The use scope of plastic material.
Invention content
The technical problem to be solved by the present invention is to, in view of the above problems, it is excellent to provide a kind of resistance to low temperature, crushing resistance
By force, low temperature resistant pressure-resistant plastic material with long service life.
In order to solve the above technical problems, technical solution provided by the invention is：A kind of low temperature resistant pressure-resistant plastic material, including
The raw material of following weight percent forms：Polyethylene 30~60%, polyethylene terephthalate 25~40%, makrolon
10~20%, compatilizer 10~15%, cold resistant plasticizer 1~10%, zinc oxide 1~5%, toughener 0.5~3%, antioxidant
0.1~1%.
As an improvement, the compatilizer is maleic anhydride.
As an improvement, the cold resistant plasticizer is dihexyl sebacate.
As an improvement, the toughener is haloflex.
As an improvement, the antioxidant is 2,6- three-levels butyl -4- methylphenols or pentaerythritol ester.
The advantages of the present invention over the prior art are that：Material provided by the invention has excellent lower temperature resistance,
It remains to show good toughness under extremely low temperature, while there is good physical mechanical property, crushing resistance, impact and flowing
Property, and ensure that the characteristic of original plastic material, the use scope of environment temperature is increased, service life is improved.
