Title:
MOLDED PRODUCT HAVING PATTERN OF ROCK TONE AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JPS63188010
Kind Code:
A
Abstract:

PURPOSE: To form easily and inexpensibly a molded product which is thin and light in weight and possesses high heat resistance, high mechanical strength and a beautiful pattern of rock tone, by a method wherein compound powdery and granular aggregate for formation of the rock-tone pattern is spread over SMC in about a fixed thickness, which is inlaid through pressurization and press molding of the SMC is performed so theat in inlaid surface of the aggregates may become outside.

CONSTITUTION: Compound powdery and granular aggregate 1 is spread over SMC 2 in about a fixed thickness. The compounded powdery and granular aggregate 1 is obtained by compounding various coarse sands, fine sands and rock-making mineral particles at an appropriate rate so as to form a desired rock tone pattern. It is preferable that a spreading thickness of the compounded powdery and granular aggregate 1 falls within a range of about a half of the thickness of the SMC 2 or thinner. The SMC 2 over which the compounded powdery and granular aggregate 1 has been spread is passed through press rolls 3, 3 and the compounded powdery and granular aggregate 1 is inlaid into a surface layer part of the SMC 2 through their rolling pressure. The SCM 2 into which the compound powdery and granular aggregate 1 has been inlaid like this is arranged between a top and bottom forces 4a, 4b of a press molding machine. Press molding of the SMC 2 is performed under heating so that the inlaid surface of the aggragate becomes outside of a molded product, the same is cured and a desired thin molded product is obtained.
