Title:
STAMPABLE MATERIAL EXCELLENT IN MECHANICAL PROPERTIES AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH0726030
Kind Code:
A
Abstract:

PURPOSE: To produce a stampable material (a glass-fiber-reinforced thermoplastic resin) evenly colored and having high strengths, elasticity, and flowability by papermaking method under conditions that a reinforcing glass fiber treated with a silane coupling agent is put into a surfactant-contg. aq. medium contg. tiny air bubbles dispersed therein and that matrix resin particles for the material contain functional groups bondable with the silane coupling agent in such a manner that the concn. of the group in each particle decreases gradually from the surface to the inside.

CONSTITUTION: Particles of a thermoplastic resin (e.g. polypropylene) and a small amt. of particles of another thermoplastic resin (e.g. polypropylene modified with maleic anhydride) are mixed under stirring to fuse the latter particles to the surfaces of the former particles, giving mixed resin particles. The mixed particles and a finely cut glass fiber pretreated with a silane coupling agent are stirred in an aq. soln. of sodium dodecylbenzenesulfonate to give a dispersion, which is poured into a papermaking machine, defoamed, and converted into a web. About four sheets of the web are stacked and thermally pressed.
