Quartz stone plate and its preparation method

Abstract

The invention relates to a quartz-stone board and a preparation method thereof. The preparation method comprises the following steps: (1) designing a pre-pressing die, namely, arranging a bulge on a pre-pressing plate, and extending the bulge to the side edge of the pre-pressing plate to form a splicing station, so as to obtain the pre-pressing die; (2) mixing unsaturated resin, a curing agent, a coupling agent, quartz sand, quartz powder and a toner mixture to obtain a plurality of mixture groups with different color, and then rolling one group to obtain wet materials; (3) pre-pressing the wet materials through the pre-pressing die, and forming concave grooves in the surfaces of the wet materials, then removing the pre-pressing die, and filling the concave grooves with the rest mixture groups and color paste; (4) performing the subsequent forming processes to obtain the quartz-stone board. According to the method, the position of the splicing station can be flexibly designed according to the requirement of actual engineering, so that the quartz-stone boards can be spliced at random; the textures on the spliced boards are continuous and in natural transition; in addition, the preparation process is stable, and batch production can be achieved.

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] Quartz stone plate is a large-scale plate made of quartz crystal, resin and trace pigments through heterogeneous polymerization technology under vacuum conditions. Its main structure is as high as 94% of quartz crystals, making it hard and compact. Other decorative materials do not have the characteristics of wear resistance, pressure resistance, high temperature resistance, corrosion resistance, and impermeability. [0003] Quartz stone slabs are available in various colors and can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.) etc.) field, is a non-radioactive pollution, reusable environmental protection, green new building interior decoration materials. [0004] But at present, the production of quartz stone slabs, especia...

AI Technical Summary

Problems solved by technology

[0004] But at present, the production of quartz stone slabs, especially the multi-color texture series slabs, cannot control the texture. When the prepared slabs are spliced ​​(such as straight splicing or L-shaped splicing), it is difficult to achieve continuous texture, and the splicing parts are often stiff and dull.
