Problems solved by technology

[0002] The existing resin-type artificial stone slab technology is to stir and mix the resin and quartz sand powder before forming the upper mold. After the resin is opened, it will chemically react with the air, and the solvent will start to volatilize. Therefore, it will be affected by time when the mold is placed. Restricted, and because the viscosity of the resin adhesive has been expressed, the material in the mold is difficult to disperse, and the distribution is uneven, resulting in the pattern on the surface of the plate and uneven density of each part of the plate. Different densities will cause different stress and easy deformation
[0003] At present, all traditional artificial stone plates use unsaturated resin as adhesive, so accelerator, coupling agent and curing agent are needed as chemical auxiliary materials. Specific disadvantages: 1. There are harmful waste gas and waste water in the process of processing
2. The board has harmful substances precipitated during use and should not be in direct contact with food
3. The surface hardness is low, generally around 6 Mohs, and the finish is poor

Abstract

The invention relates to an anti-pressure artificial stone. The stone is composed of, by weight, 80-93 parts of white cement, 12-18 parts of unsaturated resin, 24-28 parts of silica powder, 0.08-0.8 part of curing agent, 11-22 parts of metakaolin, 0.4-0.96 part of accelerant, 34-45 parts of silica fume, 40-46 parts of powdery filler, 41-53 parts of water, 60-66 parts of natural stone particles, 6-9 parts of water reducer, 23-43 parts of hollow glass microspheres, 3-5 parts of pigment and 2-3 parts of dye. The stone has the advantages that the stone is in a powdery state in mold distribution, distribution is very easy and uniform, time is not limited, soft melting bonding begins when pressure forming after distribution, patterns of the surface of a board is controllable and uniform, the density of every part of the board is uniform, stress is uniform, and deformation is not likely to happen, so that the requirements on the rigidity and the thickness are greatly improved.

Due to the viscosity of the resin adhesive, it is difficult to disperse the material in the mold, and the distribution is uneven, resulting in uneven density on the surface of the plate and various parts of the plate. Different densities will cause different stress and easy deformation.
