Abstract
The present invention discloses an environmentally friendly low friction modified plastic, prepared by the following raw materials in parts by weight: 30-60 parts of polyethylene, 30-60 parts of polyhydroxyalkanoate 10-20 parts of polybutylene terephthalate, 1-3 parts of polymer toughening agent, and 3-5 parts of ground calcium carbonate. According to the present invention, the modified plastic has higher wear resistance, and improves product strength, and by applying the polyhydroxyalkanoate (PHA) to prepare the modified plastic, the circulation recycling effect is achieved, thereby achieving the environmental protection objective.
Description
Technical field
The present invention relates to plastic applications, specifically, the particularly low mill modified plastics of a kind of environmental protection.
Background technology
General plastic corrosion-resisting, rigidity and transparency are relatively good, but easily agingly become fragile, and shock resistance and abrasion resistance are all poor.In addition plastics under physical environment be difficult to decompose, research find, polyhydroxyalkanoate (PHA) be a lot of Microbe synthesis a kind of cell in polyester, there is good Biodegradable.
More common plastic prod can make of this biological plastics material both at home and abroad.But its production cost is higher, toughness and thermotolerance are also poor, therefore have limitation, and finding the use-pattern be applicable to is existing market problem in urgent need to solve.
Summary of the invention
Technical problem to be solved by this invention is to provide the low mill modified plastics of a kind of environmental protection, this modified plastics has higher wear resisting property, improve the intensity of product, prepare by application polyhydroxyalkanoate (PHA) effect that this modified plastics reaches recycling, realize the object of environment-friendly and green.
The low mill modified plastics of a kind of environmental protection, is prepared by the raw material of following portions by weight: polyethylene 30-60 part, polyhydroxyalkanoate 30-60 part, polybutylene terephthalate 10-20 part, macromolecular toughening agent 1-3 part, water-ground limestone 3-5 part.
As optimal technical scheme, prepared by the raw material of following portions by weight: polyethylene 45 parts, polyhydroxyalkanoate 55 parts, polybutylene terephthalate 15 parts, macromolecular toughening agent 2 parts, water-ground limestone 4 parts.
As optimal technical scheme, prepared by the raw material of following portions by weight: polyethylene 30 parts, polyhydroxyalkanoate 50 parts, polybutylene terephthalate 12 parts, macromolecular toughening agent 3 parts, water-ground limestone 5 parts.
As optimal technical scheme, prepared by the raw material of following portions by weight: polyethylene 48 parts, polyhydroxyalkanoate 35 parts, polybutylene terephthalate 16 parts, macromolecular toughening agent 2.5 parts, water-ground limestone 3.5 parts.
The low mill modified plastics of a kind of environmental protection, its preparation method is: by polyethylene part, polyhydroxyalkanoate part, polybutylene terephthalate, macromolecular toughening agent, water-ground limestone mixing, stir after mixing in 2 minutes through rotating speed 1000r/min, through parallel double-screw extruder once shaped granulation, the temperature of each section of parallel double-screw extruder should control in the scope of 190-230 DEG C.
The present invention has following beneficial effect: this disclosure of the invention a kind of environmental protection low mill modified plastics, this modified plastics has higher wear resisting property, improve the intensity of product, production cost is low, prepare by application polyhydroxyalkanoate (PHA) effect that this modified plastics reaches recycling, realize the object of environment-friendly and green.
