Problems solved by technology

However, because the semi-finished product needs to be transported before curing, the surface of the semi-finished product is prone to scratches during this process, so that the finished product is scrapped
In addition, the castable used in the traditional casting process is prone to cracking in the mold, which also leads to low yield

Abstract

The invention belongs to a fast-curing casting resin for bathroom accessories and a preparing method and a using method thereof. In the fast-curing casting resin for the bathroom accessories, o-phenyl type unsaturated polyester resin is used as a matrix resin; and the fast-curing casting resin comprises the following materials in percentage by weight: 18 to 22 percent of o-phenyl type unsaturated polyester resin, 28 to 32 percent of 200-mesh calcium carbonate, 22 to 26 percent of 300-mesh calcium carbonate, 14 to 18 percent of quartz sand and 15 to 10 percent of white micro-bead. A small amount of additive is also added into the formula, and the additive comprises an accelerating agent, a low contraction agent and a curing agent, wherein the addition of the accelerating agent is 0.2 to 0.8 percent of the weight of the o-phenyl type unsaturated polyester resin, the addition of the low contraction agent is 1 to 1.1 percent of the weight of the o-phenyl type unsaturated polyester resin, and the addition of the curing agent is 1.6 to 2.2 percent of the weight of the o-phenyl type unsaturated polyester resin. The demolded semi-finished product of the casting resin does not need the steps of pressing and re-curing, so the energy consumption is greatly reduced. Meanwhile, the surface of the semi-finished product is hardly scratched, and at least 50 percent of labor can be saved.

Description

technical field [0001] The invention belongs to the production field of sanitary products, in particular to a fast-curing casting resin for sanitary products and its preparation and use method. Background technique [0002] The existing sanitary products casting process usually takes the following steps: [0003] Spray the gel coat resin in the mold first, and then cast the body of the bathroom products after the gel coat is cured. After about 30 to 40 minutes, the castable is cured and released from the mold, but the strength of the castable is only 25 to 30 when it is fully cured. %, the product is easily deformed, it needs to be placed on a flat flat shelf, and 3 to 4 sandbags are pressed, each sandbag is 4 to 5 kg, so as to avoid diagonal warping and deformation of the semi-finished product before it is completely cured. After pressing, the semi-finished product still needs to be drilled, ground and other technological steps. Due to the low strength of the semi-finished...
