The method of manufacturing artificial marble

Currently, artificial marble are made of resin production, although light, but the resin content of up to 30%, the product is easily deformed during use, bend, aging, and heat-resistant product temperature about 40 ℃, affecting life, and therefore can not exhibit a natural stone texture and texture. This patent a simulation and high transmittance can use artificial marble conventional apparatus and method for manufacturing production.
The transparent artificial marble, according to the mass ratio, the raw material of 5-100 mesh white diamond crystal or jade rosin silt from 500 to 700, ultra-fine calcium carbonate powder, 30 to 180, transparent unsaturated polyester resin is 58 to 150, 0.9 1.8 initiator, accelerator is 0.06-0.08, the pigment is 0.01 to 1.5, the transparent material is nano-SiO2 ~ 30 ~ 50.
Ultra-fine calcium carbonate as calcium carbonate powder more than 1250 projects, transparent unsaturated polyester resin using crystal resin, initiator using ketones initiator, accelerator cobalt accelerators, pigments chosen titanium, iron and yellow.
Translucent artificial marble manufacturing steps are as follows:
1, ingredients: the 5-100 mesh white diamond crystal or jade rosin silt and ultra-fine calcium carbonate powder mixed to give mixture A;
2, was added to the mix A pigment stirring time 5 ~ 2O minutes to obtain mixture B;
3, added to the mix B in people transparent unsaturated polyester resin, initiator and accelerator, mixed and stirred, followed by vacuum, vacuum degree of 60 70cmHg, and continue stirring until the material becomes lumpy after to give mixture C;
4. Add the mix C nano SiO transparent material, mixing, pumping vacuum after the material into the mold;
5, will be injected into the mold material is placed in a vacuum chamber, the oscillating pressure molding;
6, after curing, stripping, curing time ≥ hours, six days after the release of conservation:
7, according to specifications, the substrate after release cutting, sanding and finishing, that was translucent artificial marble.
The transparent artificial marble has the following advantages:
1, simple equipment, materials readily available, you can use existing equipment. A transparent resin and transparent nanomaterials solution to the traditional problem of the artificial marble can not translucent, color pigments are freely adjustable, easy to set up. Meter of different textures, different colors of light transmitting artificial marble, especially for small and medium sized stone factory, can make use of waste rock, but also the production quality and cheap artificial translucent marble.
2, marble obtained simulation and high toughness, having a granular structure, low resin content, can be processed into a sheet of 0.8mm. Production of a series of measures taken in favor of improving the quality of production of finished products; for example, stone dry feed ingredients stirred and limit its water content, and stirred in a vacuum, fabrics, oscillating pressure to remove water and low molecular weight compounds; use soft resin portion, either as liquid filler, reducing the amount of unsaturated resin; polymerization of the polymer can reduce the severity, appropriately reducing the rigidity of slate, increased toughness, to prevent cracking.
3, cost reduction, and efficiency significantly.
4, with light, heat, aging is not easy deformation, etc., heat up to 70 degrees.
