Problems solved by technology

CN102061053B discloses "a resin-based composite material sanitary ware and its preparation method". However, the unsaturated resin has the advantages of yellowing, whitening and brightening. The unsaturated resin products we are talking about mainly refer to artificial stone. This kind of product has such problems, and it is not white enough. It turns yellow again after a few days, or it turns yellow again after being exposed to the sun for a few days. This kind of sanitary ware uses unsaturated resin as adhesive, glass fiber and fabric as reinforcing material, or quartz sand, marble, calcite, etc. as raw materials. Its hot water resistance is not ideal. After long-term soaking in hot water, the surface coating will be damaged and raised, and water will destroy the bonding between polyester resin and fibers.
The acrylic bathtub has the characteristics of anti-pollution, not easy to break, not easy to scratch, warm and comfortable to the touch, and good thermal insulation performance. It is an ideal material for making bathtubs at present. Another disadvantage is that it is easy to hang dirt, it is not easy to clean, and it is noisy when draining water. , those skilled in the art urgently need to develop a production method of acrylic sanitary ware composite materials with IPN structure to meet the existing market demand and performance requirements

Embodiment 1

[0022] The first step is to prepare and weigh the following raw materials in corresponding parts by weight for subsequent use:

[0023]Liquid A: 70 parts of methyl methacrylate, 0.5 parts of initiator B, 8 parts of organically modified calcium sulfate whiskers; Liquid B: 30 parts of vinyl ester resin, 20 parts of styrene, diethylene glycol diallyl 8 parts of carbonate, 0.1 part of initiator A, 2 parts of crosslinking agent; the second step, mix A liquid and B liquid evenly, under the protection of nitrogen, pour into a closed stirring tank at 65 °C and stir for 15 minutes After that, heat up to 90°C and continue to stir for 30 minutes to carry out the polymerization reaction. After that, it is transferred to the resin impregnation tank. The process time is 1.5 minutes, the treatment temperature is 75°C, and the amount of impregnation is controlled. The forming mold adopts a three-stage gradient heating method, and the temperature range is 105°C, 115°C, and 120°C in sequence, a...

[0025] The first step is to prepare and weigh the following raw materials in corresponding parts by weight for subsequent use:

[0026] Liquid A: 60 parts of methyl methacrylate, 0.1 part of initiator B, 6 parts of organically modified calcium sulfate whiskers; Liquid B: 20 ​​parts of vinyl ester resin, 18 parts of styrene, diethylene glycol diallyl 5 parts of carbonate, 0.05 parts of initiator A, 1 part of cross-linking agent; the second step, mix A liquid and B liquid evenly, under the protection of nitrogen, pour into a closed stirring tank at 65 °C and stir for 10 minutes After that, heat up to 90°C and continue to stir for 20 minutes to carry out the polymerization reaction. After that, it is transferred to the resin impregnation tank. The process time is 1 minute, the treatment temperature is 60°C, and the amount of impregnation is controlled. The forming mold adopts a three-stage gradient heating method, and the temperature range is 115°C, 120°C, and 125°C in sequence, ...

Abstract

The invention belongs to the field of high polymer materials, and particularly relates to a production method of an IPN structure acrylic sanitary appliance composite material, and the IPN structure acrylic sanitary appliance composite material has the characteristics of light weight, good surface smoothness, low price, good high temperature resistance, pressure resistance and wear resistance, aging resistance on the surface, high surface hardness and difficult scratching, the production method is simple and easy to implement, the raw material source is wide, the equipment cost is low, and theprepared composite material of IPN structure has damping characteristic and is beneficial to reducing the water flow noise of the sanitary ware

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a production method of an IPN structure acrylic sanitary ware composite material. Background technique [0002] Sanitary ware, including bathtubs, shower room chassis, and back panels, is usually molded with acrylic plastic sheets. Because bathtubs and other products have a complex appearance and a deep molding height, they are prepared with ordinary packaging materials, and their mechanical properties and heat resistance are average. It is difficult to meet the process requirements, so the selection of suitable plates and equipment is the basis for excellent molding of sanitary ware. The plastic plates used for sanitary ware molding mainly use pure acrylic materials or ABS materials, as well as newly developed thermoplastic materials. The acrylic sheet used for sanitary ware requires excellent surface finish, high wear resistance, is not easy to rub hair, and is easy ...
