Description
Technical field
The present invention relates to the recycling field of spent high molecular material, specifically is a kind of waste rubber powder/polyolefin blend material and preparation method thereof.
Background technology
Along with the fast development of polymer industry, the usage quantity of spent high molecular material is increasing, reclaims and comprehensive utilization is the trend that the recycling economy development pattern of core has become world development with waste and old resource.The technology of recycle of exploiting natural resources energetically will exert far reaching influence to the growth and the environment sustainable development of national economy.At present, the YO of world's waste old is above 2,000 ten thousand tons.Because the cross-linked network that rubber item forms in the course of processing makes it be difficult to reprocessing, becomes black pollution easily, environment is caused have a strong impact on, recycling rubber has caused that people pay attention to widely.The recycling of waste old has several different methods, as cushioning material, sound-proof material, processes shoddy, rubber powder etc. as directly.Process rubber powder to waste old and use, not only method is simple, less energy consumption, cost are low, and has higher economic value.Generally, rubber powder can add in rubber or the plastics, is applied to road pavement, waterproof roll, plastic toughening and preparation thermoplastic elastomer etc.Chinese scholars is to the existing many reports of the applied research of rubber powder, but the interface that mostly is to improve rubber powder and rubber or plastics is to improve the intensity of intermingling material.At present there is following several method to improve both consistencies usually: to increase the contact area with matrix through rubber powder desulfurization modification; Add compatilizer or rubber powder is coated; Strengthen interface compatibility through dynamic vulcanization.The two kinds of methods in front all are to improve the performance of intermingling material through physical bond; Thereby improved performance is limited, and adding compatilizer or coating can only be directed against a kind of matrix; Must use another kind of compatilizer instead or use other material coating instead other matrix resin, therefore preparation comparatively bothers.A kind of method in back is a Chemical bond, thereby is two keys and matrix generation chemical reaction raising consistency through vulcanized rubber powder.But the two keys of vulcanized rubber powder are less, and all be in a fixed position can not free movement, thereby crosslinked limited with matrix resin, and performance improves not obvious.
Summary of the invention
The object of the invention is the deficiency to prior art; A kind of waste rubber powder/polyolefin blend material and preparation method thereof is provided; Waste rubber powder and polyolefin resin that the present invention at first will pass through surface-treated carry out the graft-blending modification; Improve the interface performance between waste rubber powder and the polyolefin resin effectively, also a kind of new way is provided simultaneously for reclaiming spent high molecular material.
Realize that the technical scheme that the object of the invention adopted is:
A kind of waste rubber powder/polyolefin blend preparation methods comprises the steps: that each component counts by weight, in mixing roll; 10 ~ 100 parts of rubber powders and 1~10 part of properties-correcting agent are carried out surface devulcanization plasticizing reaction, and the reaction times is 5 ~ 30 minutes, and controlled temperature is 100 ℃~200 ℃ then; Again with mixing 5 ~ 20 minutes of 20~100 parts of polyolefin resines; And then adding 1~20 part of grafted monomer and 1~5 part of initiator is mixing, mixing time is 5 ~ 20 minutes, can obtain required intermingling material.
The particle diameter of said rubber powder is 10~200 orders.
Said polyolefin resin is any one in ethylene-octene copolymer, polyolefin elastomer, high density polyethylene(HDPE), new LDPE (film grade), Vestolen PP 7052 or the ethylene-vinyl acetate copolymer.
Said properties-correcting agent be in phenylhydrazine, thiazole, diethylenetriamine, triethylene tetramine, TEPA, mercaptan, disulphide or the sweetening agent any one.
Said grafted monomer be vinylbenzene, maleic anhydride, SY-Monomer G, acrylic or methacrylic acid methyl esters any one or more than one.
Said initiator is any one in BPO, Di Cumyl Peroxide 99 or the ditertiary butyl peroxide.
Said mixing roll is mill, Banbury mixer or forcing machine.
Compared with prior art; The present invention has following advantage and beneficial effect: the rubber powder modified agent that the present invention adopts can make vulcanized rubber powder desulfurization plasticizing; Improved the linear lag of vulcanized rubber powder; Thereby increased the reactive behavior between rubber powder and the polyolefin resin, and connected the functional group that can participate in reaction, further increased reactive behavior with polyolefin resin.In mixing process, add grafted monomer and initiator then; Make rubber powder and polyolefin resin generation graft reaction; Polyolefin resin is grafted on the rubber powder, and between has been set up strong interface, thereby obtains having the waste rubber powder/polyolefin resin intermingling material of excellent mechanical performances.
