Abstract
The inorganic particle surface modification method is characterized by that using solvent to dissolve and dilute the monomers which can be polymerized, then stirring to make them uniformly distribute in inorganic particle dsurface, grain size of inorganic particle is 0.1-10 micrometer, then making solvent completely volatilize at 50-150 deg.C, making the inorganic particle undergo the process of UV light radiation at 0-150 deg.c (light intensity is 300-1000 w. wavelength is 280-400 nm) to initiate monomers to make polymerization reaction for 10-120 min., making polymer tightly combine with inorganic particle in grafting or settling mode. The inorganic particle whose surface is covered with a layer of polymer can be used for filling polymer matrix, can obviously improve compatibility of two-phase interface, and can raise the performance of composite material.
Description
The present invention relates to a kind of method of surface modifying inorganic particle.The modified inorganic particle is used for the filled polymer matrix, can obviously improve the consistency of inorganic particulate and polymkeric substance, and obtained performance is matrix material preferably.
Inorganic particulate is widely used in the weighting agent or the toughener of macromolecular material, not only can reduce cost significantly, and can give the performance of the various preciousnesses of material, for Application Areas that enlarges macromolecular material and reduction material cost big meaning is arranged.Yet because the chemical constitution and the configuration of surface structure of inorganic particulate and organic polymer exist great difference, must to inorganic particulate carry out that surface modification can be improved and polymkeric substance between consistency.The surface modification of inorganic particulate adopts the surface of coupling agent treatment particle more, and coupling agent commonly used has silane, metatitanic acid fat, organic chromium and zirconium class coupling agent, and the use range of wherein preceding two kinds of coupling agents is the widest.The processing mode of coupling agent treatment inorganic particulate has two kinds: a kind of is method for pretreating; Another kind is the integral blend method.Method for pretreating is with solvent coupling agent to be diluted earlier, make it to be uniformly distributed in the inorganic particulate surface by stirring at a certain temperature then, because the effect of heating, solvent is volatilized, chemical reaction takes place in coupling agent and inorganic particulate surface, thereby reaches the effect that covers the inorganic particulate surface; The integral blend method is that coupling agent is incorporated in inorganic particulate filler and the resin matrix, the mixing together link coupled effect that reaches.Adopt the coupling agent treatment inorganic filler surface, mature technical route, and obtained using widely.Yet the coupling agent treatment mode is strict to treating processes, needs CONTROL PROCESS condition such as temperature, solvent and mixing time etc. comparatively complicated, and is empirical strong, must grope rule in practice gradually.
The objective of the invention is to provide a kind of method of surface modifying inorganic particle at the deficiencies in the prior art, be characterized in polymerisable monomer is dissolved in the solvent, make it to be evenly distributed on the inorganic particulate surface by stirring, the reaction of employing uv-light polymerization, polymkeric substance is combined closely with grafting or sedimentary mode and inorganic particulate, reaches the effect of modification.
