IPC: B29C48/395
Filed: 1995-05-09
Abstract: PURPOSE: To produce a compd. easy in the control of a melt kneading condition in a screw type kneading extruder and good in a silica dispersion state. CONSTITUTION: A mixed material prepared by mixing silica with polypropylene is supplied into a barral 1 from a supply port 4. Supplied polypropylene and silica are fed to a kneading part from the supply part to be melted and kneaded by mixing elements 3 and, at this time, water is added to polypropylene from a water adding port 5 within a range of 0.2-1.5% by wt. of polypropylene. This water added from the water adding port 5 lowers the temp. of the resin in the kneading part of the barrel 1 to reduce the separation rate of moisture adsorbed on the silanol groups present on the surfaces of silica particles. As a result, silica particles are not mutually flocculated to be uniformly dispersed in polypropylene. Thereafter, the kneaded mixture is fed to a weighing part and excessive moisture and a gas component are discharged to the outside of the barral 1 from a vent port 6.
