[0003] Chinese invention patent 96106392.0 discloses an artificial marble product, but it has the following disadvantages: 1. CaO is added to the raw material formula to remove moisture, and the ratio of the water remover is not clearly defined, and the addition of CaO will affect the finished product The strength and hardness will have a certain impact, and the cost of the product will be increased after adding materials; 2. The manufacturing of sanitary equipment uses a pouring machine with screw feeding. If the equipment fails during the production process, the repair operation will seriously affect the assembly line The normal operation is unstable; 3. The surface layer and the inner layer do not use a certain durable layer, and the service life is affected
[0004] Chinese invention patent 85106057 also discloses a kind of artificial marble product, but it also has the following disadvantages: 1. In the raw materials of fillers (amorphous hydrated aluminum silicate, amorphous hydrated magnesium silicate, amorphous hydrated calcium silicate, etc.) Contains a certain amount of moisture, which may cause the filler particles to peel off after long-term use
;2. The production process is too long, and the slurry needs to be precipitated and stratified before hardening. The process is complicated and it is easy to produce defective products; 3. The surface layer and the inner layer do not use a certain durable layer, and the service life is affected.

Embodiment 1
[0044] A type of artificial marble whose structure see figure 1 , comprising three layers of waterproof surface layer 10, unsaturated polyester resin middle layer 20 and reinforcing bottom layer 30.
[0045] Among them, the waterproof surface layer 10 adopts a mixture of NR3ZP transparent gel coat, retarder TBC (playing to delay the hardening time, so that the air of the surface gel coat can escape before hardening), and hardener M-50. The mass ratio of the three is 1:0.03:0.0001.
[0046] Wherein the reinforcing bottom layer 30 adopts a mixture of DS396S unsaturated polyester resin and hardener M-50VR, wherein the mass ratio of DS396S unsaturated polyester resin to hardener M-50VR is 1:0.05; or adopts DS396S unsaturated polyester resin , hardener M-50VR, glass fiber mixture.
[0047] Wherein the unsaturated polyester resin middle layer 20 comprises the following raw materials:
[0048] Resin U-250C accounted for 34%
[0049] Glass powder 80S accounts for 65%
[0050] Def...
Embodiment 2
[0056] A method for manufacturing artificial marble bathroom equipment, the detailed process flow can be found in figure 2 , including the following steps:
[0058] Mix resin U-250 and glass powder 80S at a ratio of 1:2.5, then add defoamer BYK-A515 and accelerator NLF-10 accounting for 1% to 2% of the mixture to prepare a preliminary slurry; The weight of the bathroom equipment is weighed separately: according to the color of the finished product to be produced, weigh the required color paste and toner, and the ratio is to weigh 0.01% to 15% of the preliminary slurry, and weigh the required hardener 21S and P-16; when used, pour the weighed color paste, toner, hardener 21S and P-16 into the preliminary slurry, stir and mix, and stir and defoam in a vacuum state to obtain the slurry;
[0059] Step 2: Preparation of upper and lower molds:
[0060] Remove the foreign matter and sundries in the mold, and then apply ...

Abstract
The invention relates to imitation marble, which comprises a waterproof surface layer, an unsaturated polyester resin middle layer and a reinforcing bottom layer. A method for manufacturing bathroom equipment by using the imitation marble comprises the following steps of: preparing unsaturated polyester resin slurry, namely coating the reinforcing bottom layer on an upper die, and coating the waterproof surface layer on a lower die; when the temperature of upper and lower dies is reduced to be between 45 and 60 DEG C, starting to close the dies, namely fixing the lower die on a die closing machine, pouring the prepared slurry into the upper die, and pushing the upper die into the die closing machine to close the dies; and screwing screws on both sides of the dies simultaneously by using apneumatic tool, overturning the dies, and conveying the dies to a ripening furnace with the temperature of between 40 and 70 DEG C for hardening molding. The imitation marble has the advantages of compact combination among materials, high waterproofness and long service life. The method for manufacturing the bathroom equipment by using the imitation marble has the advantages of simple equipment, smooth production, only 5 to 7 hours of one equipment from die preparation to finished product packaging, short time and low cost, and is suitable for large-scale production.
Description
【Technical field】 [0001] The invention relates to an artificial marble and a method for manufacturing sanitary equipment using the artificial marble. 【Background technique】 [0002] As a substitute for natural marble, artificial marble has been successfully made into various industrial and civilian marble products due to its advantages such as wide source, low manufacturing cost, easy processing and rich colors compared with natural marble. Widely used in industrial production and people's daily life. [0003] Chinese invention patent 96106392.0 discloses an artificial marble product, but it has the following disadvantages: 1. CaO is added to the raw material formula to remove moisture, and the ratio of the water remover is not clearly defined, and the addition of CaO will affect the finished product The strength and hardness will have a certain impact, and the cost of the product will be increased after adding materials; 2. The manufacturing of sanitary equipment uses a po...
