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:
[0057] Step 1: Prepare unsaturated polyester resin slurry:
[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 ...
