Production process, products and molds of quartz slabs with convex and concave patterns

Abstract

The invention provides a production method of a quartzite plate with convex-concave patterns, a product and a mold. The method comprises the following steps: respectively and uniformly mixing main layer ingredients, adhesion layer ingredients and pattern layer ingredients, and producing the quartzite plate according to the following steps: 1) material spreading: firstly uniformly and flatly layingthe main layer ingredients on a bottom die, uniformly and flatly laying the adhesion layer ingredients on the main layer ingredients and finally uniformly and flatly laying the pattern layer ingredients on the adhesion layer ingredients; 2) carrying out vibration treatment for 20-40 s; 3) spraying a release agent on the template with convex-concave patterns, pressing the template on the pattern layer ingredients; 4) carrying out pressurization vacuumizing operation for 90-120s; carrying out vibration pressurization for 4-6 minutes; carrying out standing and pressurization for 10-20 minutes; carrying out heat curing operation at the temperature of 80-110 DEG C for 40-60 minutes; demoulding; and polishing the front surface of the quartzite plate. According to the invention, the cost is reduced, and the water and electricity charge, the abrasive charge, the labor cost and the like can be reduced by one half. After a thickness-free working procedure, the workshop is dry, clean and does not contain pollutants such as water vapor and dust, and the noise is greatly reduced.

Description

technical field [0001] The invention relates to a production process, product and mold of a quartz slab with convex and concave patterns. Background technique [0002] At present, all artificial quartz stone plates are flat on both sides without concave and convex patterns. The specific processing process is as follows: after batching, cloth, vacuum pressure and vibration, heat curing, demoulding, thickness setting, grinding and polishing . [0003] The thickness of the front and back sides of the board needs to be calibrated through the thickness gauge machine on the back of the board, the 180-degree turning machine, and the front side of the board. Each side needs to be ground to a thickness of 1mm to 5mm to meet the subsequent polishing requirements; if the back of the board is not processed , its roughness and unevenness affect the appearance. [0004] The existing quartz stone slabs have the following problems in production: when the thickness is set, the volatilizati...

Problems solved by technology

[0003] The thickness of the front and back sides of the board needs to be calibrated through the thickness gauge machine on the back of the board, the 180-degree turning machine, and the front side of the board. Each side needs to be ground to a thickness of 1mm to 5mm to meet the subsequent polishing requirements; if the back of the board is not processed , its roughness and unevenness affect the aesthetics

[0004] The existing quartz stone slabs have the following problems in production: when the thickness is set, the volatilization of dust and water mist is large, the noise is large, there is a large amount of grinding, the consumption of abrasives is large, the electricity and water costs are high, and the slab is easily damaged. low efficiency

In addition, currently only plates with smooth surfaces can be produced, and it is impossible to produce various embossed patterns on the surface

[0005] If you want to set concave-convex patterns on the bottom of the quartz stone, based on the current ingredients of quartz stone, it is difficult to process fine concave-convex patterns. Moreover, if the concave-convex patterns are made with ordinary molds, when the quartz stone ingredients are heated and cooled, they will expand and contract with each other. The mold produces friction, causing damage to the pattern
