Kitchen sink composite material and kitchen sink molding method

Abstract

The invention belongs to the technical field of kitchen and bath facility materials and preparation thereof, and particularly relates to a kitchen sink composite material and a kitchen sink molding method, wherein the kitchen sink composite material comprises, by mass, 15-16% of a bisphenol A epoxy resin, 0-2% of a glycidyl ether type epoxy compound active diluent, 12-14% of a liquid-state methyltetrahydroanhydride or methyl hexahydroanhydride curing agent, 0.2-0.5% of a polyamine or quaternary phosphonium salt accelerant, 67-72% of a functional filler having a relative density of 2.0-2.7, and 0.4-0.5% of fumed silica or bentonite thixotropic agent. According to the invention, the functional filler with a proper density range is filled in the epoxy resin medium-high temperature curing formula material, and the epoxy resin automatic pressure gel forming machine is used for forming the kitchen sink, so that the prepared kitchen sink product is obviously superior to the prior art in theaspects of appearance, performance, product qualification rate and the like.

Description

technical field [0001] The invention belongs to the technical field of kitchen and bathroom facility materials and preparation, and in particular relates to a kitchen sink composite material and a kitchen sink forming method. Background technique [0002] At present, the common kitchen sink materials and sink molding processes in the market are as follows: stainless steel stretching or welding, cast iron enamel, steel plate stretched enamel, glazed ceramics, conventional acrylic resin or unsaturated polyester resin or the composite resin of the two. The artificial stone of the main body is made of normal-pressure pouring artificial stone, artificial stone cut and bonded with artificial stone plates, or ordinary engineering plastics by high-pressure injection molding, or fiber-reinforced composite plastics such as SMC / BMC by high-pressure molding. have to.

Problems solved by technology

[0003] Among them, except for artificial stone materials, the above-mentioned various kitchen sink materials are all of a single color or texture, which cannot meet the preferences of consumer groups for personalized colors and textures and decoration styles; such as subsequent processing such as painting on the surface of the material will not only increase processing steps and costs, and is not environmentally friendly

As for artificial stone materials, although the color and texture can be obtained through the formula, the formula needs to be formed by low-pressure pouring process, and the obtained product has defects such as low density, low strength, no impact resistance and easy cracking, and the surface is easily polluted and difficult to clean.

Moreover, because most of them are made of low-cost glass fiber reinforced plastic molds, there are disadvantages of low dimensional accuracy, which requires a lot of grinding and polishing work in the later stage, which also increases labor costs and is not environmentally friendly.

However, for water tanks made of stainless steel by stretching or welding, the cost of molds and equipment is expensive, the post-processing process is cumbersome, the labor intensity is high and the cost is high, and the environment during the cutting and grinding process is noisy and dusty.
