How to make artificial marble?

Answer:

At present, artificial marble are made of resin production, while products are light, but because the resin content was more than 30%, make the product easy to use in the process of deformation, bending, aging, and the product of the temperature of 40 DEG C, affect the service life, and therefore can not show the natural stone texture and texture. The invention relates to a transparent artificial marble with high simulation degree, which can be produced by conventional equipment and a manufacturing method thereof.The transparent artificial marble, according to the mass ratio of the raw material is 5 to 100 mesh or Zuanjing white rosin jade powder is 500 ~ 700 sand, super fine calcium carbonate powder is 30 ~ 180, transparent unsaturated polyester resin 58 ~ 150, the initiator is 0.9 1.8, 0.06 - 0.08 promoter, pigment is 0.01 ~ 1.5, transparent nano SiO2~ material is 30 ~ 50.Ultra fine calcium carbonate powder as calcium carbonate powder over 1250 mesh, transparent unsaturated polyester resin made of crystal resin, initiator with ketone initiator, accelerator with cobalt titanium pigment, yellow accelerant, etc..
The pervious artificial marble has the following advantages:1, the equipment is simple, the material is easy to obtain, can use the existing equipment production. The use of transparent resin and nano transparent material to solve the traditional problems of artificial marble to light, color pigments are adjustable, easy to set. Calculate the artificial marble texture, different different colors of light, especially suitable for small and medium sized stone factory, which can use the waste stone, artificial marble and produce high quality and low price light.2, the marble has high degree of simulation, good toughness, with granular structure, low resin content, can be processed into 0.8mm sheet. A series of measures taken in production is helpful to improve the quality of finished products; for example, by mixing dry stone ingredients, and limit the water content under vacuum stirring, cloth, oscillating pressure to remove moisture and low molecular weight compounds; using soft resin, which can be used as the liquid filler, reducing unsaturated resin the amount of; and reduce the severity of polymerization of polymers, appropriate reduction in the slab rigidity, increase toughness, to prevent the emergence of crack.3, cost reduction, efficiency significantly.4, with light, heat, not easy to deformation, aging, heat resistance up to 70 degrees.
1, 5 to 100 ingredients: white jade or Zuanjing rosin powder and ultrafine calcium carbonate powder, mixed materials A;2, in the mixture A add pigment mixing, time 5 ~ 2O minutes, get mixture B;3, in the mixture of B add transparent unsaturated polyester resin, initiator and accelerator, mixing and stirring, and then vacuum, vacuum degree of 60 70cmHg, continue to stir until the material becomes a mass, the mixture C;4, in the mixture of C transparent nano SiO material, stirring, vacuum after the material into the mold;5, the material will be injected into the mold vacuum chamber, the oscillation pressure, molding;Release 6, after curing, the curing time is no less than 6 days after the release of maintenance hours:7, according to the specifications, the mold after the cutting, polishing and finishing, that is pervious to artificial marble.
