Title:
LOW-ADHESION MATERIAL, MOLD FOR SHAPING RESIN AND STAINPROOF MATERIAL
Document Type and Number:
WIPO Patent Application WO/2007/116571
Kind Code:
A1
Abstract:
An upper side half (1) of a resin-shaping mold which bears both a cavity member
(6) constituting the inner bottom face (5) of a cavity (4) and a surround member
(7). The cavity member (6) is a low-adhesion material according to the present
invention which is composed of a body (8) and a face (10) formed on the underside
(9) of the body (8) that is to come into contact with a fluid resin. The body (8) is
made of a material consisting of the first material 3YSZ and the second material
ZrN at a prescribed ratio. The face (10) is made of Y2O3 exhibiting
low adhesion to cured resins and has a lower thermal expansion coefficient than
that of the body (8). The cavity member (6) is produced by joining the body (8) and
the face (10) at high temperature and then cooling the obtained composite, whereby
a compressive residual stress is generated in the face (10) owing to the difference
in thermal expansion coefficient and remains in the face (10).
