Embodiment 1
[0027] A kind of environment-friendly stone material that waste rock is made, its preparation method comprises concrete following steps:
[0028] 1) First crush and sieve the waste rock to obtain stone powder. The waste rock is non-standard rough stone produced in the mining process of natural stone and leftover material produced in the processing process. The particle size of the obtained stone powder is controlled at 25- 40μm;
[0029] 2) Mix and stir the unsaturated resin (propylene glycol isophthalate) and accelerator (cobalt water) for 2 minutes, then add the stone powder, pigment, aluminum hydroxide powder and modifier obtained in step 1) and continue stirring for 5 minutes, and finally Add curing agent (methyl ethyl ketone) and mix well;
[0030] Among them, each component is counted in terms of mass parts: 35 parts of stone powder, 7 parts of unsaturated resin, 3 parts of accelerator, 32 parts of curing agent, 1 part of modifier, 0.1 part of pigment and 0.5 part of al...
Embodiment 2
[0038] A kind of environment-friendly stone material that waste rock is made, its preparation method comprises concrete following steps:
[0039] 1) First crush and sieve the waste rock to obtain stone powder. The waste rock is non-standard rough stone produced in the mining process of natural stone and leftover material produced in the processing process. The particle size of the obtained stone powder is controlled at 25- 40μm;
[0040] 2) Mix and stir the unsaturated resin (propylene glycol isophthalate) and accelerator (cobalt water) for 2 minutes, then add the stone powder, nano photocatalyst, pigment, aluminum hydroxide powder and modifier obtained in step 1) and continue stirring 5min, finally add curing agent (methyl ethyl ketone) and mix well;
[0041] Among them, each component is calculated according to the number of parts by mass: 40 parts of stone powder, 9 parts of unsaturated resin, 4 parts of accelerator, 40 parts of curing agent, 3 parts of modifier, 0.4 part ...
Embodiment 3
[0049] A kind of environment-friendly stone material that waste rock is made, its preparation method comprises concrete following steps:
[0050]1) First crush and sieve the waste rock to obtain stone powder. The waste rock is non-standard rough stone produced in the mining process of natural stone and leftover material produced in the processing process. The particle size of the obtained stone powder is controlled at 25- 40μm;
[0051] 2) Mix and stir the unsaturated resin (propylene glycol isophthalate) and accelerator (cobalt water) for 2 minutes, then add the stone powder, nano photocatalyst, pigment, aluminum hydroxide powder and modifier obtained in step 1) and continue stirring 5min, finally add curing agent (methyl ethyl ketone) and mix well;
[0052] Among them, each component is counted as: 40 parts of stone powder, 10 parts of unsaturated resin, 4 parts of accelerator, 48 parts of curing agent, 5 parts of modifier, 0.5 part of pigment, 0.04 part of nano photocataly...
