According to the mass ratio, the transparent artificial marble comprises the following raw materials: 500-700 mesh 5- 100 mesh white diamond crystal or rosin jade powder sand, 30- 180 ultrafine calcium carbonate powder, 58- 150 transparent unsaturated polyester adhesive, 0.910.8 initiator and 0.
Ultra-fine calcium carbonate powder is 65,438+0,250 mesh calcium carbonate powder, which is transparent and unsaturated. Polyester glue accepts transparent crystal glue, initiator accepts ketone initiator, accelerator accepts cobalt accelerator, and pigments are titanium dioxide and iron yellow.
The manufacturing steps of transparent artificial marble are as follows: 1, batching: white diamond crystal or rosin jade powder sand with 5- 100 mesh and superfine calcium carbonate powder are stirred to obtain a mixture a; 2, adding pigment into the mixture A, and stirring for 5-2o minutes to obtain a mixture B; 3. Adding transparent unsaturated polyester adhesive, initiator and accelerator into mixture B, mixing and stirring, then vacuumizing with the vacuum degree of 6070cmHg, and continuously stirring until the materials are agglomerated to obtain mixture C; 4, adding transparent nano-silica material into the mixture c, stirring, vacuumizing and pouring into a mold; 5, placing the mold filled with materials in a vacuum chamber, and performing vibration compression molding; 6, demoulding after curing, wherein the curing time is not less than hours, and curing for 6 days after demoulding; 7. Cutting, polishing and finishing the demoulded base material according to the specification requirements to obtain transparent artificial marble. -wholesale sale of calcium powder
The transparent artificial marble has the following advantages: simple equipment, easily available materials, and can be produced by using existing stone equipment. Transparent glue and transparent nano-materials are used to solve the problem that traditional artificial marble can't transmit light, and the primary color pigment can be adjusted at will, which is convenient to set. This kind of transparent artificial marble with different textures and colors is especially suitable for small and medium-sized stone factories, which can not only make use of coal gangue, but also produce transparent artificial marble with high quality and low cost. 2. The marble has high simulation, good toughness, granular structure and low glue content, and can be processed into a 0.8 mm thin plate. A series of measures taken in production are helpful to improve the quality of finished products; For example, when stone ingredients are mixed with dry materials, their water content is limited. They are mixed, distributed and vibrated under vacuum to remove water and low molecular compounds. Using part of soft rubber can not only be used as liquid filler, but also reduce unsaturation and rubber content; It can also reduce the severity of polymer polymerization reaction, appropriately reduce the rigidity of slate, increase toughness and prevent cracking. 3. The cost is reduced and the benefit is remarkable. 4. It has the advantages of light transmission, heat resistance, difficult deformation and aging, and the heat resistance can reach more than 70 degrees. -Production and supply of calcium powder in Henan Province
