The composite material has excellent mechanical performance, heat performance and outer appearance.
Description
Technical field
The present invention relates to a kind of novel high polymer/inorganic particle composite material, specifically, the present invention relates to a kind of polymer/inorganic particle composite material that adopts rare-earth modifier.
Background technology
Plastic toughening is the emphasis problem of polymer material science research always, the rubber-like elastomerics is scattered in the plastic substrate in a suitable manner, can reach toughness reinforcing purpose, this method for toughening research is more, and obtained than ten-strike, but when elastic body toughening improved plastics toughness, the strength of materials, rigidity, modulus and thermotolerance but declined to a great extent.
Inorganic particle filled modified high-molecular is existing to be used quite widely, and inorganic particulate is many in the occurring in nature kind, storage is wide, be easy to processing, cheap.Inorganic particulate and polymer are compound, and its purpose has two: one, reduce cost, and the 2nd, give system some particular performances.Discovered in recent years, some rigid particles not only can improve rigidity, the modulus of macromolecular material under certain condition, and polymer toughness is improved.Generally, because inorganic particulate is high polar water-insoluble, surface energy is higher, and polymkeric substance mostly is apolar substance, and surface energy is low, the two consistency is poor, inorganic particulate is difficulties in dispersion in high polymer molten, and dispersed uniform is poor, a little less than the matrix effect, thereby it is a lot of generally all to cause system performance degradation, particularly impact property to descend.Therefore, when preparation polymer/inorganic particle composite material, using various properties-correcting agent that modification is carried out on the surface of inorganic particulate handles, make it to realize as far as possible the coupling of aspect such as surface property, chemical property, soda acid performance and even how much patterns and macromolecular material, cause honest and clean, as to improve over-all properties purpose in the hope of reaching toughness reinforcing, charge with matrix.
In early days, people adopt tensio-active agent such as stearic acid, stearate etc. as properties-correcting agent, and its cost is low, but because of the modification at filling surface belongs to physical action, modified effect is not ideal enough; Various subsequently coupling agents occur in succession, and the performance of inorganic particle filled macromolecular material is improved by a relatively large margin.But existing business-like coupling agent, still exist and improve problems such as effect is not remarkable: the silane coupling agent viscosity reducing effect is obvious, and more or less a hundred kind is arranged so far, is mainly used in glass filament reinforced plastics and rubber industry, and for polyolefin resin, DeGrain during fillers such as its processing lime carbonate; Coupling agents such as titanate coupling agent, boric acid ester, zirconium aluminate, modified effect is relatively good, but properties-correcting agent cost height, and often need to adopt operations such as thinner and spraying be reinforced when carrying out modification, cause complex process equipment, and wherein the affiliation that adds of some metal ion causes degradation problem under the matrix material ageing resistance; US3, the aluminium esters of gallic acid coupling agent of 905,936 grades inventions, modified effect is good, but has problems such as facile hydrolysis, association, and it is also less to be used for the kind of thermoplastic resin; We found once that some rare earth compoundings had certain surface treatment effect (Chinese plastics, the 10th phase of calendar year 2001) to lime carbonate, made aspects such as filler parent granule but be used as properties-correcting agent for rare earth material, did not appear in the newspapers.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of production technique simple, be easy to process, the inorganic particles/polymer composite material of excellent performance.
In the inorganic particles/polymer composite material of the present invention, except that containing inorganic particulate and resin material, also contain the rare-earth modifier that modification is carried out on described inorganic particulate surface, and the synergist that increases the effect of rare-earth modifier surface modification.
After adopting rare-earth modifier of the present invention that the inorganic particulate filler is carried out surface modification, can make the surface of inorganic particulate become close organic property, thereby realize between mineral filler and the matrix resin good affine from the inorganic performance of parent.And adopt the synergist of rare-earth modifier of the present invention, can further improve the processing characteristics of composite system, and the consistency of inorganic particulate and body material.
