Embodiment 1

[0018] A kind of bathroom BMC material, comprises the raw material of following percentage by weight: unsaturated polyester (o-phthalate neopentyl glycol resin) 17%; Low shrinkage resin (saturated resin containing propylene glycol) 9%; Release agent (calcium stearate ) 1.8%; color paste 1%; mixture of calcium carbonate and aluminum hydroxide 56%; curing agent (tert-butyl peroxide 2-ethylhexanoate) 0.2%; glass fiber 15%.

[0019] A preparation method of BMC material for bathroom, comprising the steps of:

[0020] 1. Add the resin, curing agent, release agent and color paste into the kneader and stir for 20 minutes to obtain a uniformly stirred liquid;

[0021] 2. Add the mixture of calcium carbonate and aluminum hydroxide into the evenly stirred liquid, and stir for 20 minutes to obtain a well-mixed paste;

[0022] 3. Add glass fiber evenly and stir for 10 minutes to get the mixed material product.

Embodiment 2

[0024] Others are as described in Example 1, difference is: comprise the raw material of following percentage by weight: unsaturated polyester (vinyl resin) 18%; Low shrinkage resin (saturated resin containing propylene glycol) 10%; Release agent (stearic acid Calcium) 3%; color paste 1%; mixture of calcium carbonate and talcum powder 50%; curing agent (tert-amyl peroxide 2-ethyl acetate) 0.5%; glass fiber 17.5%.

Embodiment 3

[0026] Others are as described in Example 1, difference is: comprise the raw material of following percentage by weight: unsaturated polyester (o-phthalate neopentyl glycol resin) 12%; Low shrinkage resin (PMMA solution) 4%; Release agent (stearin barium acid) 2.7%; color paste 1%; calcium carbonate 65%; curing agent (tert-butyl peroxide 2-ethylhexanoate) 0.3%; glass fiber 15%.

Abstract

The invention provides a BMC material for a bathroom. The BMC material comprises unsaturated polyester resin, low-shrinkage resin, a release agent, filler, a curing agent and glass fiber. The unsaturated polyester resin is o-phenyl neopentyl glycol resin or vinyl resin. The low-shrinkage resin is propylene-glycol-containing saturated resin or a PMMA solution. The filler is arbitrary one of or a mixture of more of calcium carbonate, aluminium hydroxide and talcum powder. The invention further provides a preparing method of the BMC material for the bathroom. The unsaturated polyester resin and low-shrinkage resin are reasonably selected; bathroom products have high color and luster and high shrinkage resistance through the synergistic effect of the unsaturated polyester resin and low-shrinkage resin, finally the technical effect of improving the surface flatness is realized, and particularly the class-A surface of a vehicle can be obtained.

Description

technical field [0001] The invention belongs to the technical field of BMC materials, and in particular relates to a BMC material for bathroom and a preparation method thereof. Background technique [0002] At present, most of the laundry tubs and bathtubs used in bathrooms are casted, and the volatile organic compounds (VOC) of casted products are easy to exceed the standard, and the strength is low, the size is unstable, the molding cycle is long, the operation is difficult, the efficiency is low, and it is not environmentally friendly. , is currently starting to use BMC material compression molding. Products molded with BMC materials have high strength, good dimensional stability, high effect, and environmentally friendly materials. However, the existing common BMC materials are difficult to meet the requirements of high-gloss surface, strong stain resistance, and high surface flatness for bathrooms. Contents of the invention [0003] The invention provides a bathroom...
