Embodiment 1
[0042] A high-performance artificial marble comprises the following raw materials in parts by weight: 12 parts of matrix resin, 60 parts of filler, 0.7 part of curing agent, 0.3 part of accelerator, 4.5 parts of pigment, and 15 parts of flame retardant.
[0043]Wherein, the matrix resin is formed by mixing unsaturated polyester resin, modified epoxy resin, and silicone modified polyurethane resin with a mass ratio of 6:4:1; the preparation method of the modified epoxy resin is: Add water-based epoxy resin emulsion and silane coupling agent in the reactor, add 232% water, 5% dibutyl phthalate and 0.8% dodecyl dimethyl in the ratio of water-based epoxy resin emulsion weight Betaine was heated up to 55°C and reacted for 1.5 hours to obtain a modified epoxy resin.
[0044] The filler is formed by mixing marble waste rock powder, modified nickel slag and modified waste glass at a mass ratio of 5:3:1; the average particle size range of the marble waste rock powder is 5-6mm, and the ...
