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
What the present invention relates to is matched lid of a kind of water closet or ring, and the mold pressing manufacturing process, belongs to cleaners and polishes product and die press technology for forming.
Background technology
In the prior art, the toilet lid or the toilet circle that are used to be matched in water closet adopt conventional plastic mould pressing to form basically, the product that this conventional plastic material is made, defective such as it is low to exist intensity, easily aging.Though some toilet lid or toilet circle are to adopt wooden or bamboo material is made, it is easily dirty that they exist the surface, and defective such as easily be corroded.In addition, it is to make with ceramic material or resin that a small amount of toilet lid or toilet circle are also arranged, but the former is frangible, the cost height; Latter's preponderance use inconvenience, and cost is also higher relatively.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and a kind of intensity height is provided, cost is low, long service life, the lid of the simple water closet of production technology or ring and production technology.
The objective of the invention is to finish by following technical solution, the lid of described water closet or ring, it adopts die press technology for forming to make, and its inside is density board, and outside the parcel with the SMC composite material forms sandwich shape.
