Abstract
The invention provides a waste PE plastic recycle additive, comprising any antioxidant of antioxidant 1010, antioxidant 2246, antioxidant 264 and DLTP, any olefin containing 5-15 carbons and couplingagent which contains any substance selected from silane, titanate and organic acid chrome complex. The recycled waste PE pipe which is processed by the additive provided in the invention can be comparable with original PE plastic in chemical resistance, solvent resistance and moisture permeability.
Description
Technical field
The present invention relates to a kind of useless PE (polyethylene) plastic recycle additive, specifically relate to a kind of waste PE plastic regeneration pipeline material auxiliary agent.
Background technology
Existing P E waste plastic renovation process generally is that the PE waste plastic is reheated plasticizing, makes it enter behind the viscosity flow state pelletizing again and the method that is used.This method makes the macromolecular chain depolymerization because PE waste plastic high-temperature heating inequality, loss original auxiliary agent partly in the PE waste plastic, even carbonization, big havoc the mechanical property of PE waste plastic.Traditional PE waste plastic working method is to process under the situation of band moisture content, because the heating means of band moisture content can make the further aging and carbonization of plastics.Therefore, no matter the PE reprocessed plastic(s) tubing that processes with this method decreases at chemical-resistant, solvent resistance, all more former PE plastics of water vapour permeability aspects.
Summary of the invention
The present invention seeks in order to solve the deficiency that the above-mentioned background technology exists, proposition technology is simple, with low cost, pollution-free, as not have discharging a kind of PE waste plastic regeneration materials auxiliary agent makes regenerated PE waste plastic tubing no matter all can reach the index of former PE tubing in chemical-resistant, solvent resistance or water vapour permeability.
A kind of injection molding auxiliary agent of plastic waste that is used for provided by the invention, said auxiliary agent comprises antioxidant, polystyrene, vinyl acetate between to for plastic acetate copolymer, polystyrene, alkene, coupling agent and maleic anhydride.
In the preferred promoter provided by the invention, by weight, said antioxidant is 0.01-0.15 part, polystyrene 6-8 part, vinyl acetate between to for plastic acetate copolymer 10-15 part, polystyrene 16-20 part, alkene 15-20 part, coupling agent 0.1-0.8 part and maleic anhydride 2-5 part.
Preferred promoter provided by the invention is that said antioxidant is that antioxidant is any one antioxidant of selecting from antioxidant 1010, antioxidant 2246, antioxidant 264 and DLTP; Said alkene is that carbonatoms is any one alkene in the alkene of 5-15; Said coupling agent is any one material of selecting in silane, titanic acid ester and the chromium of organic acid complex compound.
A preferred promoter more provided by the invention, said alkene are that carbonatoms is the alkene of 5-10; Said coupling agent is with general formula Si
nH
2n+2Silane, wherein n is 2 to 5 integer.
The 3rd preferred promoter provided by the invention, said antioxidant are antioxidant 1010, and said alkene is the alkene of carbonatoms 8-10.
Make at regeneration PE tubing with modified additive provided by the invention and all can match in excellence or beauty with former PE plastic pipe at chemical-resistant, solvent resistance, ventilation property, water vapour permeability aspects.
Specific embodiment
Other has except the explanation, and institute of institute part is weight part among the application.
Embodiment 1
