Detailed Description
Three examples of the production process of the quartz stone slab with the convex-concave patterns of the invention are as follows:
example 1:
the main layer ingredients comprise the following components in percentage by weight: 7% of resin, 12% of 60-mesh quartz sand, 15% of 80-mesh quartz sand, 20.5% of 800-mesh quartz powder, 15% of 400-mesh quartz powder, 6% of 10-mesh glass, 15% of 40-mesh glass, 8% of 80-mesh glass, 1% of curing agent and 0.5% of silane coupling agent.
The adhesive layer ingredient comprises the following components in percentage by weight: 19% of resin, 10% of 80-mesh quartz sand, 65% of 800-mesh quartz powder, 3% of alumina powder, 1% of curing agent, 1% of silane coupling agent and 1% of butyronitrile phenolic resin glue.
The pattern layer ingredient comprises the following components in percentage by weight: 20% of resin, 75% of 1200-mesh quartz powder, 3% of alumina powder, 1% of curing agent and 1% of silane coupling agent.
The main layer ingredient, the adhesion layer ingredient and the pattern layer ingredient are respectively and uniformly mixed to prepare the quartz stone plate according to the following steps,
(1) material distribution: uniformly spreading the main layer ingredients on a bottom die, spraying a release agent or paving a layer of kraft paper on the bottom die, wherein the thickness of the main layer ingredients is 12mm, uniformly spreading the adhesion layer ingredients on the main layer ingredients, wherein the thickness of the adhesion layer ingredients is 2mm, and performing vibration treatment for 25 s; and finally, uniformly spreading the pattern layer ingredients on the adhesion layer ingredients, wherein the thickness of the adhesion layer ingredients is 3mm, and performing vibration treatment for 10 s. The main layer, the adhesion layer and the pattern layer are formed from bottom to top in sequence. Main layer batching, adhesion layer batching and decorative pattern layer batching cloth from bottom to top, its principle is as follows: in the vibration pressurizing process, the ingredients at the bottommost part can be pressed more compactly, the flatness of the bottom part is high, the surface of the main layer is compact, the stability of the product is improved, and the anti-seepage effect is good. The workload of the subsequent polishing process is reduced after the surface is flattened. The pattern layer is arranged on the uppermost layer, and because the pattern layer is used for pressing patterns, slight unevenness caused by few local materials does not influence the overall vision, so that the defective rate of products is greatly reduced. The cloth structure of the invention also solves a problem: when the decorative pattern layer is placed at the bottom, the main layer can press the decorative pattern layer, the uniform thickness of the decorative pattern layer is damaged, and the pressed decorative pattern is influenced.

According to the invention, after the adhesion layer cloth and the pattern layer cloth are finished, vibration treatment is respectively carried out, and because the adhesion layer and the pattern layer contain more resin, if vibration is carried out at the same time, the phenomenon that the adhesion layer and the pattern layer are partially lacking (namely, the adhesion layer is gradually thickened in a certain area, and the pattern layer is gradually thinned to cause that the pressed pattern is not beautiful, or the pattern layer is gradually thickened downwards to cause that the adhesion layer is thinned, and the pattern layer is directly contacted with the main layer to cause that the bonding strength is small) is easily caused, so that the whole pattern effect and the bonding strength are influenced. The process is different from the prior art in that the vacuum pumping is firstly carried out and then the pressurizing vibration is carried out, and aims to ensure that the junction of the main layer, the adhesion layer and the pattern layer can be mutually permeated and fused by the vibration treatment, and then the vacuum pumping and the pressurizing are carried out, so that the three layers are integrated, the bonding strength is improved, and the lines can not be seen from the appearance after the fusion.
