Abstract
A waste plastic high-performance environment-friendly regeneration technology comprises the following steps that firstly, waste plastic is collected and put into a vibrating screen to separate large impurities, then the waste plastic is ground into grains, and the grains are fed into cold air drying equipment; secondly, the plastic grains dried with cold air are fed into a vacuum rolling machine for rolling treatment, vacuum pumping is carried out once every 5-8 min in the rolling process, and rolling is carried out for 5-10 min after each time of vacuum pumping; thirdly, the rolled plastic grains are taken out and sprayed with pure water for washing; fourthly, the sprayed plastic grains are drained to remove moisture and then fed into drying equipment for drying treatment until no moisture exists on the surfaces of the plastic grains; fifthly, the dried plastic grains are fed into low-temperature ring equipment for low-temperature treatment; sixthly, the plastic grains subjected to low-temperature treatment are ground, and the ground plastic grains pass through an 80-mesh screen and then are fed into refrigerating equipment for cold-resistant treatment; seventhly, the plastic grains subjected to cold-resistant treatment are fed into an extruder for extruding granulation, and thus modification of plastic is completed.
Description
Technical field
The present invention relates to plastics modification technology field, be specifically related to a kind of waste or used plastics high-performance environment-friendly regeneration
Technique.
Background technology
Since nineteen thirty modern plastics industry is formed, through more than 80 years develop rapidly, plastics industry was
Through becoming the mainstay of light industry.Plastic product wide variety of while, also create huge
Plastic pollution, the ecological environment to the whole world causes destruction greatly.Processing method to waste plastic garbage
Mainly landfill disposal and burning disposal, but landfill disposal takes up room relatively big due to it, adds soil
Ground resource pressure, simultaneously because useless moulding is difficult to degrade, the serious infiltration hampering water and subsoil water circulation,
Secondly giving up the additive in moulding also can be to soil reclamation secondary pollution.Burning disposal due to burning produce CO,
Polycyclic aromatic compound and heavy metal can be discharged together with incineration residue along with flue dust and cause environment
The biggest pollution.Along with the progress of science and technology, start to occur utilizing plastic reclaimed machinery to waste or used plastics
Carry out regenerating and modifying, just achieve resources circulation in real consciousness.
For recycling these waste plastics, need it is crushed, clean, separate impurity etc.,
Traditional recovery process and reclaimer technology content are the highest, and cost recovery is big, the sexual valence attached by recovery
Ratio is unsatisfactory.The regenerated plastics quality of preparation is the highest, is only used for part low-end product and uses.Especially
Being to use in some special environments, under low temperature environment, environment under high pressure, common reworked material cannot be expired
The working environment of foot high intensity, resistance to low temperature is poor, easy embrittlement.And also there is impact strength relatively
Low, elastic and that anti-stress cracking performance is poor defect, causes bigger to the development of plastic reclaimed industry
Impact.
Summary of the invention
The technical problem to be solved is to provide a kind of physics, stable chemical performance, preparation letter
Single waste or used plastics high-performance environment-friendly regeneration technology.
The technical problem to be solved realizes by the following technical solutions:
A kind of waste or used plastics high-performance environment-friendly regeneration technology, it is characterised in that the method step is as follows,
(1) collect waste or used plastics, put into be fallen by big magazins' layout in vibrosieve, mould waste and old the most again
Material is ground into graininess, sends into cold wind drying plant, cold air drying 30-35 minute at temperature 50-55 DEG C,
Make plastic grain dry tack free, it is simple to follow-up cleaning；
(2) plastic grain after cold air drying is sent into vacuum tumbler and carry out tumbling process, every during tumbling
Every 5-8 minute evacuation once, exhaust tumbling 5-10 minute, then vacuum pumping after vacuum every time, so follow
Ring 2-4 time so that plastic grain can reach to breathe the effect of massage in tumbling procedure, improves surface and lives
Property, make the impurity on surface start to decompose；
(3) plastic grain after tumbling is taken out, carry out cleaning showers with pure water, spray 4-5 continuously
Minute, processing owing to have passed through tumbling, the foreign material on plastic grain surface and oil stain are easy to fill to be washed off,
Flushing water can be recycled after precipitation process；
(4) plastic grain after spray is drained away the water, send in drying plant and carry out drying and processing, dry
Dry temperature controls at 55-60 DEG C, to plastic grain surface without moisture；
(5) plastic grain after drying is sent in low temperature ring apparatus and is carried out K cryogenic treatment, and temperature controls
Subzero about 15 DEG C, K cryogenic treatment 20 minutes；The advantage of K cryogenic treatment is to improve the resistance to low of regenerated plastics
Warm nature energy；
(6) plastic grain after K cryogenic treatment is pulverized, cross 80 mesh sieves, then the plastics that will pulverize
Grain feeding freezing equipment, freezing 40 minutes under subzero 25 DEG C of environment, carry out cold-resistant process；The most effective
Improve the dispersion effect of matrix, and send out with ABS under the effect of activator during reactive extrursion
Raw reaction, plays the effect of chain extension, improves the mechanical property of waste or used plastics goods.
(7) ratio of the plastic grain after cold-resistant process with activator 1:0.05-0.1 in mass ratio is mixed
Close, send into extruder extruding pelletization, i.e. complete modifying plastics.
Described activator is by silane coupler 20g, age resister 10g, procyanidin 10g, antistatic additive
5g, sodium polyphosphate 5g and lubricant 5g make；
Described silane coupler is vinyltrimethoxy silane, VTES, vinyl
Triacetoxysilane, vinyl three tert-butoxy silane or γ-(methacryloxypropyl) propyl group trimethoxy
The one of base silane.
Owing to waste or used plastics surface exists hydroxyl so that it is be difficult in the base disperse, surface can be relatively big and incline
To in reunion, commonly use coupling agent at present and waste or used plastics is carried out surface modification treatment.Used by the present invention
Activator in waste or used plastics surface treatment process, there is chemical bonding or thing with waste or used plastics surface
Reason adsorption；Such activator is in regeneration process of waste plastics, after waste or used plastics surface is modified,
Its surface is become hydrophobicity by hydrophilic, improves the compatibility with matrix, and the mechanical property of product obtains
Improve.
The invention has the beneficial effects as follows: the present invention uses waste plastic to be to produce raw material, by plastics
Having carried out modification, the plastic grain of preparation may be used for the production of various goods, as food package box,
Furniture, container etc.；The product of preparation has higher intensity, nonhazardous, acid and alkali-resistance, anticorrosive,
