Compared with the Epoxy resorcinol-formaldehyde resin pretreatment system and Maleic anhydride pretreatment system developed by Xusigui, the 40% carbolated styrene-butadiene latex system can keep the composite"s properties and reduce the cost of pretreatment and simplify the pretreatment technology; especially to the HST 2073 latex system, the composite"s mechanics properties are improved greatly. Secondly, the composite"s comprehensive properties and interface performance are improved by reinforced with short fiber grafted with rubber in the surface. Thirdly, to simplify the production technology of composite, we add TKM-M and RF-90 as adhesive agent to the composite blended in an internal mixer, so as to the composite can be used to industry widely, then the effect of the amount adhesive agent on the composite"s properties and interface adhesive performance was studied, from the experiments the optimum amount of adhesive agent was deduced.
