Abstract

PURPOSE:To obtain a quality feeling such as appearance, the touch or a heavy feeling same to or similar to that of original lacquered ware by mixing a thermoplastic resin with a pulp fiber and forming the resultant mixture into a plate- shaped board by a papermaking process to mold pulpboard and molding the pulpboard under heating. CONSTITUTION:A mixture prepared by mixing a thermoplastic resin with a pulp material in an amt. capable of developing binder function, a plasticizer function and strength retaining function after molding is molded into a cardboard shape using papermaking technique and calendar processing is applied to both surfaces of the molded one to smooth them to form a material (pulpboard) 1. For example, in a process molding a handle jig of a fusuma, a teacup holder or a plug socket for a wall surface, the pulpboard 1 is processed into a processing material 1a having the shape before press molding a final product 1c and the processing material la is heated to form an intermediate product 1b molded into the shape of the final product 1 by a mold and finish processing such as surface painting or grinding is applied to the intermediate product 1b to obtain the final product 1c.

い。Next, in the heating step, for example, by using a low temperature baking machine, the temperature is 180 to 250 ° C. (efficient molding can be performed).
It is possible to heat the resin to some extent and use a low-cost heat-resistant resin mold in the molding process. However, it is possible to simultaneously perform heating and molding with a conventional heating die, and even in the case of not being heat molding, it is easier to mold the mold by heating to about 80 ° C. The compression pressure may be about 10 to 20 kg / cm.
