Abstract

The invention discloses a quartz stone board and a manufacturing method of the quartz stone board. High-viscosity unsaturated polyester resin is adopted in raw materials in proportion. The manufacturing method includes the following steps: (1) wet materials obtained after the raw materials are mixed are pre-pressed; (2) screen cutting is carried out on the wet materials pre-pressed in the step (1); (3) pigments and toner mixing materials are sprayed to cluster materials cut in the step (2), and then the follow-up molding work procedure is carried out to obtain the quartz stone board. By means of the quartz stone board and the manufacturing method, the high-viscosity resin and the wet materials are introduced into a formula to be pre-pressed, so that a foundation is laid for large-figure line board face appearance; the maximum diameter of the clustered wet materials is controlled through the large-screen quantitative cutting, and the quantitative toner mixing materials are sprayed, so that the appearance quality of the board face is guaranteed; the obtained product is stable in quality and appearance, the batch number is larger than 50, and the percent of pass of the board is higher than 98%.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to a quartz stone plate and a preparation method thereof. Background technique [0002] Artificial quartz stone slabs are currently widely used in furniture, laying floors and walls of various buildings, etc. Artificial quartz stone line pattern series products are generally produced by unsaturated polyester resin and quartz stone powder filler, but the existing production process is complicated and unstable, it is difficult to achieve stable mass production, and the obtained products have a high defect rate and low production efficiency. [0003] In the current process operation, most of them are qualitative operations. If the wet material is not pre-pressed, the wet material after stirring is directly sieved or even directly sprinkled with color powder. The process fails to achieve refined quantitative control, which makes the appearance of the product fluctuate significa...
