Problems solved by technology

[0003] Recently, artificial agate or acrylic has been used to prepare sanitary ware. See the Chinese invention patent "Acrylic toilet made by pouring process" (authorized announcement number: CN126923C) with the patent number ZL200410040962.6. The components are all prepared by pouring the mixture of resin and agate powder into the interlayer hollow shell to prepare the toilet. Although the obtained product has the general characteristics of ceramic products, the process is complicated, the cost is high, and the thickness is limited, and the self-cleaning property is not good. good

Embodiment 1

[0041] Embodiment 1: 18% unsaturated polyester resin, 10% polyester type anti-shrinkage agent, 20% nylon fiber (length 3-5mm), nylon fiber is reinforcing fiber, 10% polyester fiber (length 5-10mm), Polyester fibers are also reinforcing fibers, 13% of 1200-mesh wollastonite particles, 27% of 1000-mesh calcium carbonate powder, 3% of color paste, and 1% of initiator. The initiator adopts tert-butyloxybenzoate (TBPB) and benzoyl peroxide (BPO), and the weight ratio of tert-butyl peroxybenzoate to benzoyl peroxide is 1:2. The sanitary products prepared in this embodiment are thin and light, with smooth lines and arcs, and the tensile strength can reach 70 MPa, and the compressive and bending strengths are both over 100 MPa.

[0042] The unsaturated polyester resin in this embodiment adopts Shangwei 928 produced by Shangwei Enterprise Co., Ltd., and its unsaturated resin solid content is 35% to 40%, and the rest is styrene; the polyester type anti-shrinkage agent adopts Shangwei S...

Embodiment 2

[0043] Embodiment 2: 16% unsaturated polyester resin (upper latitude 928), 12% polyester type anti-shrinkage agent (upper latitude 7310), 5% polyphosphazene micron fiber (length 3-6mm), 10% polyester fiber (length 5-10mm), 15% 1200 mesh wollastonite particles, 32% 1000 mesh calcium carbonate powder, 8% aluminum hydroxide powder, 3% color paste, 1% initiator. The bathroom products prepared in this embodiment have excellent flame retardancy, reaching UL94V-0 level, and at the same time, have the characteristics of high temperature resistance and corrosion resistance, and can maintain normal temperature state without cold feeling. The phosphazene microfibers in this embodiment are reinforcing fibers, which play a role in enhancing the strength and toughness of the product.

Embodiment 3

[0044] Embodiment 3: 16% polyphosphazene modified unsaturated polyester resin (diphenoxy polyphosphazene), 12% polyester type anti-shrinkage agent (upper latitude 7310), 6% nylon fiber (length 3-5mm) , 12% polyester fiber (length 5-10mm), 20% 1200 mesh wollastonite particles, 32% 1000 mesh calcium carbonate powder, 3% color paste, 1% initiator. The water contact angle of the bathroom product in this embodiment reaches 95°, the waterproof performance is significantly improved, the surface of the product is not easy to accumulate dirt, has self-cleaning effect, high hardness, and ideal impact resistance and abrasion resistance.

[0045] The percentages in the above embodiments are all percentages by mass, and the bathroom products in the embodiments can be washbasins, bathtubs, toilets, bidets, urinals, shower trays, etc.

Abstract

The invention discloses a resin matrix composite material sanitary appliance, which is characterized in that: raw materials are mixed, injected and cured in a die to form the resin matrix composite material sanitary appliance; and the raw materials comprise the following components in percentage by weight: 14 to 30 percent of unsaturated polyester resin, 6 to 14 percent of polyester anti shrinking agent, 11 to 37 percent of reinforcing fibers, 10 to 20 percent of grammite, 25 to 40 percent of calcium carbonate and 0.8 to 2.4 percent of initiator. The invention also discloses a preparation method for the sanitary appliance. Compared with the prior art, the resin matrix composite material sanitary appliance has the advantages of high strength, high toughness, good self-cleaning property andlow energy consumption.

Description

technical field [0001] The invention relates to a sanitary ware, in particular to a composite material sanitary ware with resin and wollastonite as main raw materials. The invention also discloses a preparation method of the sanitary ware. Background technique [0002] Common sanitary wares include bathtubs, basins, toilets, urinals and bathtubs. They are made of ceramics. Ceramics need to be fired, which is not friendly to the environment. At the same time, a lot of rare earth resources are used in the production process, and rare earth mineral resources are relatively scarce. If things go on like this , there is bound to be a certain pressure on mineral resources. [0003] Recently, artificial agate or acrylic has been used to prepare sanitary ware. See the Chinese invention patent "Acrylic toilet made by pouring process" (authorized announcement number: CN126923C) with the patent number ZL200410040962.6. The components are all prepared by pouring the mixture of resin and...
