Lid or seat-ring of toilet bowl and production technique thereof

Abstract

The invention discloses a lid or a seat ring of a toilet bowl and a production technique thereof. The lid or the seat ring is produced by adopting a compression molding technique, a density plate is arranged inside, and a mixed SMC material covers the outside, thus forming a sandwich shape; the production technique comprises following steps: 1. SMC is prepared: various materials are synthesized according to a certain proportion, broken up by a high-speed blender for being completely mixed, and then prepared into a sheet shape for use; 2. a sandwich layer is prepared: the density plate is cut into required shapes and dried, thus leading the density plate not to contain moisture; the density plate is vacuated and air contained in the density plate is exhausted; the density plate is placed into a freezing case for storage; 3. compression molding is carried out: a die is heated until the temperature reaches 150 DEG C, the density plate and a certain amount of SMC are placed into the die, compressed for 3 to 6 minutes and taken out. The invention is characterized by having the advantages of good surface lustrousness and good product flatness, with weight of lighter than that of toilet lids made of pure SMC materials, adoption of the one-time compression molding technique without usage of paints, long service life and the like.

Description

technical field [0001] The invention relates to a cover or a seat ring for a water closet and a molding process, belonging to sanitary ware products and a molding process. Background technique [0002] In the prior art, the toilet lid or the toilet seat used to match the flush toilet is basically molded from conventional plastic materials. Products made of such conventional plastic materials have defects such as low strength and easy aging. Although some toilet lids or toilet seats are made of wood or bamboo materials, they have defects such as surfaces that are easy to get dirty and corroded. In addition, there are also a small number of toilet lids or toilet seats made of ceramic materials or resin, but the former is fragile and expensive; the latter is too heavy, inconvenient to use, and relatively high in cost. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a lid or seat and a produ...
