Description
Technical field
The invention belongs to field of compound material, be specifically related to a kind of composite regenerative plastic and preparation method thereof.
Background technology
Along with the develop rapidly of plastics industry, waste or used plastics also increases year by year.According to relevant measuring and calculating, the amount of plastic waste is about 50% of a plastics ultimate production.If these waste or used plastics can not in time be recycled, not only cause the huge wasting of resources; The more important thing is and cause great environmental pollution.Plastics-production depends on oil, and oil is to develop the resource that forms by up to a million years, has non-renewable character, so the using priciple of plastics is decrement, regeneration, utilizes.The recycling of waste or used plastics is needs of economic development still not, also is the needs of protection environment.The recovery of China's waste or used plastics has only about 20% at present, and developed country then reaches about 70%.Therefore, China need strengthen reclaiming and utilizing waste plastics.Waste plastic is containing huge value of exploiting and utilizing as a kind of new resource, and the sustainable regenerated using of waste or used plastics is the general trend of reprocessed plastic(s) development.
The regenerated using of waste or used plastics at present has several main routes.(1) carry out primary letter sorting, cleaning, recycling, the technology of these class methods is fairly simple, because reprocessed plastic(s) are through repeatedly processing; The mechanical property of plastics reduces, colour-darkening, processing difficulties; Even degraded appears, directly uses the lot of unstable factor to occur; (2) take different technologies means such as blend, modification to improve reprocessed plastic(s) over-all properties and range of application; (3) produce coating etc. through pyrolysis recycle plastics-production petroleum gas or through dissolving, but owing to have high input, complex process, cost is high, has limited large-scale development; (4) utilize waste or used plastics to burn and carry out energy recovery, its defective is to produce objectionable impurities, destroys earth outer space ozonosphere, causes global warming and forms acid rain, jeopardizes human body health.
Reprocessed plastic(s) mostly are the mixtinite of multiple plastics at present, are difficult to guarantee the stability of use, and therefore, reprocessed plastic(s) mostly are applied to the low side plastics.For example reprocessed plastic(s) are used for Wood plastic composite, modifying asphalt, plastic concrete etc., have brought into play the regenerated using of reprocessed plastic(s) preferably through modification, blend, technique means such as compound.But be limited to Effect on Performance such as reprocessed plastic(s) intensity, processibility, these utilize mode all not have really to bring into play the natural characteristics of plastics, make waste or used plastics rest on the aspect of utilizing of extensive style.Be used for the value that the middle and high end plastics will greatly improve the reprocessed plastic(s) application if make reprocessed plastic(s) recover the satisfactory stability performance through the advantages of simplicity and high efficiency regenerative use technology.Therefore, how with waste or used plastics through modification, the characteristics and the performance of reduction plastics itself are the keys of realization waste plastic regeneration recycle.
Publication number is that the patent of CN101798410A is formed complicated, high, the ropy defective of cost to reprocessed plastic(s); A kind of prescription that utilizes waste PP and PE compound to produce reprocessed plastic(s) is disclosed; Through utilizing a spot of maleic anhydride, light calcium carbonate to improve the quality of reworked material, make reworked material be used for large scale plastic product.This patent has only proposed a kind of prescription from the consistency aspect to material improvement, and material still is mixed into the master with PP, PE, does not solve processing stability, and cost does not obviously reduce yet.
Publication number is the renovation process that CN101851363A discloses a kind of waste polyethylene.Strengthen through waste polyethylene, linking agent, nano material is crosslinked in twin screw extruder, original position, obtain the regenerated polythene of molten state.The present invention is through intensity and creep-resistant property crosslinked and use nano material raising reworked material.But Drawing abillity does not improve, and especially for multiple composition blended waste or used plastics, owing to differed by the linking agent influence degree, causes the regenerability of regenerated polythene unstable.
To above problem; The present invention is compound through material of main part inorganic powder and a spot of waste or used plastics; By specific performances such as the transparency of inorganic powder, thermotolerance, flowabilities, good transparent, heat-resisting, the processing stability of the reprocessed plastic(s) that reduced can, expanded the use range of reprocessed plastic(s); Reduced the reprocessed plastic(s) cost, for the recycling utilization that realizes waste or used plastics has found a new breakthrough mouth.
Summary of the invention
It is the preparation method of the composite regenerative plastic and the said composite regenerative plastic of main body material with inorganic powder that the present invention provides a kind of.Problem such as the invention solves that the waste or used plastics mixing element is complicated, intensity is low, poor stability, poor processability, appearance luster are gloomy.
The invention provides a kind of composite regenerative plastic, it is characterized in that counting by weight by 50-70 part inorganic powder, 20-40 part waste or used plastics, 5-10 part abrasive, 3-10 part softening agent, 2-8 part toughener and form.
It is that 6000-10000 order, specific refractory power are 1.40-1.60, have in stratiform or cancellated WHITE CARBON BLACK, vermiculite, mica, talcum powder, expanded glass microballon, permanent white, the agalmatolite one or more that said inorganic powder material is selected particle diameter for use.
Said waste or used plastics can be selected each the analog thermoplastic waste or used plastics through the letter sorting granulation for use, like new LDPE (film grade) (LDPE), high density polyethylene(HDPE) (HDPE), metallocene PE (MPE), linear low density polyethylene (LLDPE), Vestolen PP 7052 (PP), Injecatable EVA Copolymer (EVA), ethylene-acrylic acid copolymer (EAA) or multiple mixture.
Said abrasive is meant one or more in Poly Propylene Wax, polyethylene wax, Microcrystalline Wax, Fischer-Tropsch wax, EVA wax, white oil, the paraffin.
Said softening agent is meant one or more in SULPHOSUCCINIC ACID ESTER, ATEC, boric acid ester, glyceryl monostearate, the Di Iso Decyl Phthalate.
Said toughener is rare multipolymer of styrene-butadiene-styrene block copolymer, ethene-Xin or their mixture.
The preparation method of composite regenerative plastic of the present invention, its material composition can be operated according to following method:
1 ＇ under 120-140 ℃ of temperature condition, mixes inorganic powder, abrasive in high-speed mixer
