Abstract
The invention relates to a biodegradable plastic motor shaft sleeve and a preparation method thereof. The biodegradable plastic motor shaft sleeve comprises the following components in percentage by weight: 5-30% of PBS(poly (butylene succinate)), 5-50% of PLA (polylactic acid), 0-20% of PBST (poly (butylene succinate)/butylene terephthalate), 0-50% of inorganic powder, 1-10% of plasticizer and 0-5% of compatibilization modifier. The preparation method of the invention is simple and flexible. The prepared material can be formed by injection machining processes, and can be prepared into motor shaft sleeves of various specifications. The material has low cost, excellent performance and wide development space, can be recycled and can be biologically degraded after being discarded, thereby meeting the requirement of environmental protection.
Description
Technical field
The present invention relates to a kind of plastics motor shaft sleeve and preparation method, relate in particular to a kind of Biodegradable plastic motor shaft sleeve and preparation method.
Background technology
Come in the past few decades, the development of plastics industry mainly is that to be based upon with the oil be on the synthetic resins on basis.But oil is one type of resource-constrained, non-renewable resource, and price increase has in recent years brought no small impact to plastics industry.At present, study and define the additional and alternative strategy of petroleum resources that minimizing, renewable resources and enforcement utilize renewable resources, guarantee the plastics industry Sustainable development, become one irresistible trend.Simultaneously; Because plastic refuse more difficult natural degradation in environment; Particularly disposable plastic products waste light weight, big, the dispersion, dirty and messy of amount are difficult to collect, and the environmental pollution that causes thus is on the rise; Thereby suffer censuring of the various countries environmental administration and the public, brought stern challenge undoubtedly for developing plastics industry.
Along with development and national economy, China has stepped into the ranks of world plastics big country.The plastics ultimate production has reached more than 4,000 ten thousand tons, occupies the second in the world.Show that according to State Statistics Bureau's latest data the annual waste plastic amount that produces is about 6,000,000 tons.Because it is corrosion-resistant that plastics have, not labile characteristic causes potential harm to environment, has become the environmental problem that various circles of society pay close attention to.At present, the degradative plastics product is all being studied by many countries, the alternative existing plastic prod that has.Domestic also have some colleges and universities, and institute is at research and development biodegradable plastic film and biological degradation injecting products, but exploitation and produce the suitable inorganic powder filled biological degradation injection raw material of interpolation and make cheap and good-quality motor shaft sleeve, at home beyond example still.Biodegradation type product of the present invention; Adopt PBS, PLA, three kinds of complete degradable plastics of PBST by the proper ratio blend, and add suitable inorganic powder filledly, production biological degradation injection raw material is made the biological degradation motor shaft sleeve; Through the domestic literature retrieval, do not find to have the bibliographical information of identical content.
Summary of the invention
The present invention is directed to big, the dispersion, dirty and messy of disposable plastic motor shaft sleeve waste amount, be difficult to collect the environmental pollution that causes thus; A kind of Biodegradable plastic motor shaft sleeve and preparation method are provided; The preparation method is simple, and product cost is lower, meets high standard environmental protection demand.
The present invention realizes through following technical scheme:
Composition and weight percent thereof that this Biodegradable plastic motor shaft sleeve comprises are: PBS (poly-succinic acid-butanediol fat) 5-30%; PLA (POLYACTIC ACID) 5-50%; PBST (poly butylene succinate/mutual-phenenyl two acid bromide two alcohol ester) 0-20%; Inorganic powder 0-50%; Softening agent 1-10%; Compatibilized modifier 0-5%.
Described inorganic powder is lime carbonate, talcous a kind of or their mixture.
Described softening agent is a kind of of terepthaloyl moietie, glycerine, Xylitol, sorbyl alcohol, maltose alcohol, polyvalent alcohol or their mixture.
Described compatibilized modifier is a kind of of the ethylene acrylic acid co polymer that comprises polar group, ethylene ethyl acrylate, maleic anhydride grafted ethene acetate ethylene copolymer.
The preparation method of Biodegradable plastic motor shaft sleeve of the present invention; By above-mentioned weight percent the mixture of PBS, PLA, PBST, inorganic powder, softening agent, compatibilized modifier being stirred 10-20min at high-speed mixer makes and mixes; Then on injection moulding machine, be injection molded into motor shaft sleeve, injection temperature is controlled at 150-230 ℃.
The present invention has following substantive distinguishing features and marked improvement: 1, through making the Biodegradable plastic motor shaft sleeve performance obtain regulation and control at wide region to raw material and adjustment proportion of raw materials, satisfy the different size demand of product.2, the present invention is with conventional complete processing injection moulding, and the preparation method is simple, flexible, and machine-shaping property is good.3, the present invention uses inorganic powder can obtain cheap goods as weighting material in a large number.4, the present invention is because of the wide model of raw material sources, and less investment has good social benefit.
