Method for manufacturing transparent artificial marble

At present, artificial marble is produced with resin. Although the product is light-transmissive, the resin content is as high as 30%, which makes the product easy to deform, bend and age during use. The heat-resistant temperature of the product is about 40°C, which affects the service life. Therefore, the texture and texture of natural stone cannot be displayed. This patent provides a light-transmitting artificial marble that has high simulation and can be produced by conventional equipment and a manufacturing method thereof.

The translucent artificial marble, according to the mass ratio, the raw material is 5-100 mesh white diamond crystal or rosin jade powder sand is 500-700, ultra-fine calcium carbonate powder is 30-180, and transparent unsaturated polyester resin is 58-150 , The initiator is 0.9 1.8, the accelerator is 0.06-0.08, the pigment is 0.01-1.5, and the transparent nano-SiOz~ material is 30-50.

Ultra-fine calcium carbonate powder is calcium carbonate powder above 1250 mesh, transparent unsaturated polyester resin uses crystal resin, initiator uses ketone initiator, accelerator uses cobalt accelerator, and pigment uses titanium dioxide, iron yellow, etc.

The manufacturing steps of translucent artificial marble are as follows:

1. Ingredients: stir 5 to 100 mesh white diamond crystal or rosin jade powder sand and ultra-fine calcium carbonate powder to obtain mixture A;

2, add the pigment to the mixture A and stir for 5 to 2O minutes to obtain the mixture B;

3, add transparent unsaturated polyester resin, initiator and accelerator to the mixture B, mix and stir, then vacuum, the vacuum degree is 60 70cmHg, continue to stir until the material becomes agglomerate, to obtain the mixture C;

4. Add transparent nano SiO material to the mixture C, stir, and pour the material into the mold after vacuuming;

5. Place the injection mold into the vacuum chamber, oscillate and apply pressure, and form;

6, demoulding after curing, curing time ≥ hours, curing for 6 days after demolding:

7. According to specifications, cut, polish and finish the demoulded base material to obtain light-transmitting artificial marble.
