Description
Technical field
The present invention relates to a kind of ultra-high molecular weight polyethylene composite material.
Background technology
Ultrahigh molecular weight polyethylene(UHMWPE) (be called for short UHMWPE) be a kind of viscosity-average molecular weight more than 1,500,000, have the thermoplastic engineering plastic of excellent properties, it has common polythene and incomparable wear resistance, shock-resistance and the resistance to low temperature of other engineering plastics.Although ultrahigh molecular weight polyethylene(UHMWPE) has above-mentioned excellent properties, but, because ultrahigh molecular weight polyethylene(UHMWPE) is nonpolar, the adhesive power of itself and other material is low, lack interface affinity and can not with defectives such as mineral filler is bonding well, limited it and in fields such as polyblend and polymer composites, be applied even more extensively.
In the prior art,, carry out blend with other polymkeric substance etc. again, can improve compatibility between components significantly, the performance of product is significantly improved by behind grafting polar group on the ultrahigh molecular weight polyethylene(UHMWPE) macromolecular chain.Therefore, utilizing ultrahigh molecular weight polyethylene(UHMWPE) superpolymer and other monomer blends or graft modification to prepare functionalized polymkeric substance, is to enlarge a kind of simple of macromolecular material purposes and efficient ways.
But ultrahigh molecular weight polyethylene(UHMWPE) is because its molecular weight is very high, and the molecular chain height tangles, and makes melt viscosity high, and melt flow index is zero, so the method for available graft modification is also few.
Usually, grafting method mainly contains scorification, solution method, radiation method and plasma method etc.Pass through as U.S. A.B.Brennan etc.
60The Co-gamma-rays is at the UHMWPE surface grafting; Japan Nishino, Takashi etc. carry out finishing with the maleic anhydride graft reaction to the UHMWPE casting film; Korea S I.Yim Chae etc. are with the indefiniteness district on bi-functional monomer crosslinked UHMWPE surface, and it is crosslinked to use superoxide to carry out volume under molten state, modifies UHMWPE to strengthen its wear resistance.Domestic, Tsing-Hua University uses SBS that UHMWPE is carried out modification, and as seen, the UHMWPE process for modifying surface has received some concerns abroad, and domestic correlative study is carried out seldom.The percentage of grafting of solution grafting is higher, but difficult solvent recovery is difficult for carrying out scale operation; In addition, use radiation and plasma body all to need light source, the production unit complexity, output investment ratio is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of novel ultra-high molecular weight polyethylene composite material with high-adhesion, in its preparation process, the solvent usage quantity is few, and production unit is simple, is convenient to suitability for industrialized production.
