Abstract

The invention relates to the processing field of building materials-man-made synthetic stone, in particular to a manufacturing method of nano synthetic travertine, solving the problems that the surface of current man-made synthetic stone lacks particle sealing and the inner part lacks a microcellular structure. The manufacturing method comprises the following steps: 1. aggregating and stirring, mixing intensively mineral sand, stone powder and binding agent; 2. feeding and mixing, adding light material-vitrified micro beads into the mixed base stock and mixing intensively; 3. distributing materials comprehensively, simultaneously spraying mixed color pastes onto the mixed base by utilizing an air sprayer; 4. vibrating and moulding, sawing and grinding to obtain a great plate with shiny side; 5. combining surface layer: preparing nano polyester surface layer material, spraying the mixing material onto the plate surface of a burnish great plate by utilizing the air sprayer; and 6. drying and slitting. The invention has reasonable technological process and strong actionability; the processed synthetic travertine products have the advantages of light weight, heat preservation, antibacterium, self-cleaning and representation of the romantic charm of natural travertine, thus being applicable to decorations of wall surface, ground surface and table facet of medium and high grade.

Description

technical field [0001] The invention relates to the field of building material-artificial synthetic stone processing, in particular to a production method of nano-sized synthetic travertine. Background technique [0002] The current artificial marble (granite) is made of marble ore, calcium carbonate powder and unsaturated polyester resin as the main raw materials, and is formed by vacuum, vibration and compression processes, and then solidified, sawed, ground and cut. Subsequent processes are made to a density of 2.5g / cm 3 decorative facing bricks. This kind of synthetic product made of marble with a Mohs hardness of about 3.5 degrees, although it has the disadvantages of poor wear resistance and poor anti-seepage performance, but with the advantages of transparency and slip resistance of the stone particles It is widely used in indoor floor decoration, and in the process of microcrystallization and texture improvement, it has rapidly developed into a production capacity ...
