Skill.
Background technology
Vinyon is a kind of, and the convenient bag that we usually carry is exactly polyethylene, and polyethylene is the simplest high score of structure
Son and most widely used high molecular material, currently, plastics in injection molding process, often will appear various waste materials, this
A little materials can not directly be re-worked use because having already passed through injection molding, and direct discarding can result in waste of resources and environment
Pollution, currently in order to the considerations of reducing cost, most producers are crushed pulverizer is sent directly into after garbage collection, so
After the waste material after crushing is mixed with raw material by a certain percentage afterwards, then it is molded again through technique, though this mode
Cost is so reduced to a certain extent, but the performance of the product after combining waste material to be molded often is less than the performance of original product,
It is unfavorable for the stabilization of original product performance.
Invention content
The purpose of the present invention is to provide a kind of recycling modified techniques of waste polyethylene plastics, to solve above-mentioned background skill
Being crushed pulverizer is sent directly into after garbage collection currently on the market that art proposes, then by the waste material after crushing by one
It after certainty ratio is mixed with raw material, then is molded again through technique, although this mode is reduced into a certain extent
This, but the performance of the product after waste material injection molding is combined often to be less than the performance of original product, it is unfavorable for original product performance stabilization
The problem of.
To achieve the above object, the present invention provides the following technical solutions：A kind of recycling modification work of waste polyethylene plastics
Skill, including broken, cleaning, drying, configuration modified feedstock, mixing, extruder extrusion system material, cooling air-drying pelletizing,

(4) modified feedstock, 50 parts of drying materials of configuration, 30 parts of polyvinyl chloride, 6 parts of foaming agents, 5 parts of heat stabilizers, 5 are configured
Part fire retardant；
(5) it mixes, the modified feedstock that will be configured in (4) is added in blender and is mixed；
(6) extruder squeezes out system material, and mixed modified feedstock is added in extruder and carries out melting extrusion；
(7) cooling air-drying pelletizing, the semi-finished product material that extruded machine machine squeezes out, after sink cooling and air-dry machine air-dry, then
Pelletizing is carried out through pelleter.
Preferably, the foaming agent is tetrachloroethanes.
Preferably, the heat stabilizer is dibasic lead phosphite.
Preferably, the fire retardant is brominated epoxy polymer-type fire retardant.
Preferably, the processing temperature of the extruder is 198-260 DEG C.
Compared with prior art, the beneficial effects of the invention are as follows：The recycling modified technique of the waste polyethylene plastics, can be right
Waste polyethylene plastics are recycled again, can save production cost, and carry out modification again to waste polyethylene plastics,
So that waste polyethylene plastics is recycled again, be conducive to the saving to resource, and can avoid excessive waste polyethylene modeling
Material pollutes the environment, and is conducive to the protection to environment, and fire retardant is added in reaction raw materials, adjustable high density polyethylene modeling
The flame retardant effect of material.
Specific implementation mode
Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution：A kind of recycling modified technique of waste polyethylene plastics, including it is broken, clear
It washes, dry, configuring modified feedstock, mixing, extruder extrusion system material, cooling air-drying pelletizing,
(1) it is crushed, first the waste polyethylene raw material of recycling is classified, after classification, waste polyethylene raw material is added
It is crushed in crusher, and broken raw material is sieved, ensure broken raw material between 200-600 mesh, sieved
After point, the not up to raw material of crushing effect is crushed again by crusher, between reaching 200-600 mesh；
(2) it cleans, broken raw material is put into service sink machine and is cleaned；
(3) it dries, after the cleaning of broken raw material, is added in drying, carries out drying and processing；
