Document Type and Number:
Japanese Patent JPH05294699
Kind Code:
A
Abstract:
PURPOSE: To injection-mold the hydraulic composition containing wollastonite in stead of asbestos into the molding having an excellent performance under an extrusion pressure.
CONSTITUTION: 1-30 pts.wt. of wollastonite, 1-30 pts.wt. of at least one compound selected from talc, mica and chlorite, 0.3-3 pts.wt. of a cellulose detivative, and 0.05-2 pts.wt. of an aliphatic polymer sulfonic acid salt and/or an aliphatic polymer carboxylic acid salt are added to 100 pts.wt. of a hydraulic inorganic substance. Pulp and/or synthetic fiber short fibers may be further added to the mixture.
