Description
Technical field
It is a kind of preparation method of high impact resistance polypropylene composite material specifically the present invention relates to a kind of composite and preparation method thereof, belongs to polymeric material field.
Background technology
Polypropylene (PP) is a kind of general-purpose plastics of high comprehensive performance, and high intensity, high tenacity PP composites can be obtained by composite.This kind of composite is widely used in the fields such as automobile, household electrical appliances, packaging.In automotive field, high-impact PP composites have turned into the main flow of automobile bumper material.Toughening modifying is one of main research direction in PP blending and modifyings, and [5 canopy j, the high-impact PP for developing has been widely used as material dedicated for bumper to the research report of existing many this respects both at home and abroad.But while PP toughness is improved, how to improve its mobility and rigidity, be still the emphasis of current research to meet the requirement of the maximization of its product and slimming.The author is in order to develop the PP composites of high fluidity, high tenacity and high rigidity, it is matrix resin to differ larger PP from two kinds of mobility, (ethylene/octene) copolymer (POE) is toughener, surface-modified superfine talcum powder is combined for filler carries out tertiary blending, have studied the influence to system performance such as each group distribution ratio, filler surface treatment mode, develop the satisfactory high-impact PP composites of notch impact strength high, good fluidity, performance, and applied as automobile bumper material.
The means of polypropylene impact energy are improved including following several：（1）The elastomeric materials such as EP rubbers and POE are incorporated into polypropylene；（2）The nanoparticulate fillers such as calcium carbonate are filled into polypropylene.But to elastomeric material is introduced in polypropylene its rigidity can be caused to significantly reduce,.There are problems that particle aggregation when nano-particle is filled in polypropylene, dispersion of the nano-particle in polypropylene is difficult to control.In order to improve polyacrylic impact resistance ability, elastomeric material and filler can also be incorporated into polypropylene simultaneously, or realized by improving polyacrylic crystal property, but it is difficult to the characteristics of taking into account the good impact resistance of polypropylene material and its good original high-modulus, high intensity and heat resistance.Polypropylene material is modified by different methods, its impact resistance ability is obviously improved under conditions of the rigidity of holding polypropylene material will not be reduced substantially, realize material modified rigidity-toughness balanced, be the key problem during polypropylene material is modified.This problem is resolved, it is necessary to rationally determine material system composition, the optimization processing at material inner structure spatial distribution and interface is effectively improved.
The content of the invention
It is an object of the invention to, solve the problems, such as to improve PP composite material impact property in the prior art, its naphthalene impact capacity is obviously improved under conditions of the rigidity of holding polypropylene material will not be reduced substantially, so as to realize the rigidity of modified material and the balance of toughness.
High impact resistance polypropylene composite material that the present invention is provided and preparation method thereof, it is made up of acrylic resin, calcium carbonate superfine powder filler and elastomeric material, wherein acrylic resin is 100 weight portions, and calcium carbonate superfine powder filler is 14~30 weight portions, and elastomeric material is 7~15 weight portions；The size of the calcium carbonate superfine powder filler is 6000~7000 mesh, it is surface-treated with Aluminate again after first passing through stearic acid surface coupling processing, stearic acid dosage is the 0.2~2% of calcium carbonate superfine powder filler weight, treatment temperature is 90~120 DEG C, Aluminate consumption is the 0.5~1.5% of calcium carbonate superfine powder filler weight, and treatment temperature is 90~120 DEG C.
The acrylic resin is homopolymerization isotactic polypropylene resin.
The size of the calcium carbonate superfine powder filler is 6500 mesh.
The weight ratio of the calcium carbonate superfine powder filler and elastomeric material is 2:1.
The elastomeric material is the copolymer of ethene, propylene or other small molecule vinyl monomers.
The elastomeric material is EP rubbers, POE.
The ionic size of the elastomeric material is suitable with the particle size of acrylic resin, i.e. the order of magnitude of two kinds of material particles sizes is close.
Calcium carbonate superfine powder filler of the present invention from specific granular size, and surface coupling and hydridization treatment are carried out to it using Aluminate, it is dispersed without producing reunion in elastomer and acrylic resin melt, and effective strengthening action can be produced to composite, the strand based on acrylic resin mutually tangles and forms network structure in increasing composite.Elastomeric material and treated calcium carbonate superfine powder filler are separately added into polypropylene, through the process of self-organization of material internal in one-step method melt blending recombination process, surface treated calcium carbonate superfine powder particle is coated by elastomer, and then tenacity-increased profax resin, obtain the polypropylene modified composite material with rigidity-toughness balanced feature.Compared to the prior art, the cost of the Filling and modifying of polypropylene composite that the present invention is designed into is relative with former acrylic resin, and room-temperature impact strength and low temperature impact strength also improve substantially.
