THERMOPLASTIC HYDRAULIC COMPOSITION, FORMED PRODUCT PREPARED FROM THE COMPOSITION BY HARDENING THROUGH HYDRATION THEREOF, AND METHOD FOR PREPARING THE FORMED PRODUCT

摘要

The object of the present invention is to produce general machine parts, OA machine part, and the like which can be produced by injection molding and which have excellent mechanical properties, thermal resistance, dimension stability and processability. The thermoplastic hydraulic composition of the present invention comprises 100 parts by weight of two types of thermoplastic resins differing in melting point and from 500 to 1000 parts by weight of a hydraulic composition. It is characterized by further comprising from 1 to 200 parts by weight of a fiber and/or from 0.5 to 10.0 parts by weight of a releasing agent added. It is characterized in that the hydraulic composition preferably is a mixed powder which comprises from 50 to 90 wt % of a hydraulic powder and from 10 to 50 wt % of a non-hydraulic powder having an average particle diameter of 1/10 that of the hydraulic powder or less.
