Embodiment 1

[0064] Embodiment 1, 18 parts of upper latitude 928 unsaturated polyester resins, 12 parts of upper latitude 7310 polyester type anti-shrinkage agents, 8 parts of nylon 66 chopped fibers, 12 parts of polyester chopped fibers, 40 parts of 1250 orders or 600 orders Wollastonite particles, 5 parts of aluminum hydroxide particles, 3 parts of color paste, 2 parts of benzoyl peroxide (BPO) and 1 part of tert-butyl oxybenzoate (TBPB) initiators are fully mixed. The mixture is pre-cured for 12 hours in a temperature environment of 40-50°C, and then pressed into a mold, kept in a temperature environment of 80°C for half an hour, and kept in a temperature environment of 130-140°C for 1 hour. After the pressed product is cooled, it is released from the mold to obtain the product.

[0065] The tensile strength of the cured material can reach 70MPa, and the compressive and bending strengths exceed 100MPa. The surface of the obtained product is smooth, and the pencil hardness reaches 6H. ...

Embodiment 2

[0066] Embodiment 2, 16 parts of upper latitude 928 unsaturated polyester resins, 10 parts of upper latitude 7310 polyester type anti-shrinkage agents, 12 parts of nylon 66 chopped fibers, 15 parts of polyester chopped fibers, 38 parts of 1250 orders or 600 orders of silicon Limestone particles, 5 parts of aluminum hydroxide particles, 2 parts of color paste, 2 parts of benzoyl peroxide (BPO) and 1 part of tert-butyl oxybenzoate (TBPB) initiator are fully mixed. The mixture is pre-cured at a temperature of 40-50°C for 12 hours, and then injected into a mold at a temperature of 150-180°C. After the product is cooled, it is post-cured at 150°C for 1 hour, and the finished product is demoulded.

[0067] The tensile strength of the cured material can reach 70MPa, and the compressive and bending strengths exceed 100MPa. The surface of the obtained product is smooth, and the pencil hardness reaches 6H. Tested by Shanghai Institute of Quality Supervision, Inspection and Technology, ...

Embodiment 3

[0068] Embodiment 3, 17 parts of upper latitude 928 unsaturated polyester resins, 11 parts of upper latitude 7310 polyester type anti-shrinkage agents, 7 parts of nylon 66 chopped fibers, 12 parts of 6 mm glass fibers, 39 parts of 1250 orders or 600 orders of silicon Limestone particles, 6 parts of aluminum hydroxide particles, 4 parts of color paste, 2 parts of benzoyl peroxide (BPO) and 1 part of tert-butyl oxybenzoate (TBPB) initiator are fully mixed. The mixture is pre-cured for 12 hours at a temperature of 40-50°C, and then injected into a mold at a temperature of 150-180°C. After the product is cooled, it is post-cured at 150°C for 1 hour, and the finished product is obtained after demoulding.

[0069] The surface of the obtained product is smooth, showing a marble-like pattern, and the pencil hardness reaches 5H and 6H. Tested by Shanghai Institute of Quality Supervision, Inspection and Technology, the product was soaked in water at 60°C for 2 hours, and the test result...

Abstract

The invention relates to resin-based composite material sanitary ware hardware which is characterized by being prepared by mixing, injection or pressure and mould curing with raw materials; and the components and the weight ratio thereof are as follows: 8 to 19 unsaturated polyester resin; 8 to 12 polyester anti-shrinkage agent; 13 to 46 reinforced fiber; 20 to 40 wollastonite; 5 to 8 aluminum hydroxide; 1 to 3 initiator; and 1 to 5 color paste. The invention also discloses a preparation method of the sanitary ware hardware. Compared with the prior art, the invention has the advantages that the low-cost wollastonite is selected as the main raw material, the hardware is prepared by injecting or pressing wollastonite into a mould at high pressure and curing the wollastonite in the mould, the cost and the energy consumption is low, and simultaneously, the strength and the toughness of the product are high, the self-cleaning property is good, the wear resistance is good and dirt is not easy to be accumulated.

Description

technical field [0001] The invention relates to a sanitary ware hardware with resin and wollastonite as the main composite materials. The sanitary ware hardware includes various kitchen and bathroom faucet shells, floor drain components and water meter cases, etc. The invention also discloses the sanitary ware hardware method of preparation. Background technique [0002] At present, the commonly used kitchen and bathroom faucet shells are made of copper-zinc alloy materials, which are sand-cast and formed, and then polished and polished before being electroplated. There are problems of cumbersome procedures and low production efficiency; secondly, a large amount of metal resources are used in production. , the cost is high; finally, the current production of sanitary ware hardware needs to melt the metal and then cast it, which belongs to the field of high energy consumption and high carbon emission, especially for the energy saving and emission reduction required by today'...
