Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for preparing an environmentally friendly quartz stone slab. Through a specific mixing sequence of raw materials, it is possible to avoid the mixing process between the color material, quartz sand and resin, and the gap between each raw material. Agglomeration will seriously affect the quality of quartz stone slabs. In addition, by controlling the conditions of pressing and curing, the compactness of the prepared quartz stone slabs can be improved to a certain extent, thereby solving the problem of water absorption of the prepared quartz stone slabs. Insufficient antifouling performance, quartz sand, quartz powder, tourmaline, and silicon micropowder are compounded in unsaturated polyester resin to form a stable cross-linked network, the deformation adaptability range is greatly improved, and the prepared quartz stone is further improved. The overall mechanical properties of the plate solve the problem that the proposal in the patent publication number CN110330263A will lead to insufficient water absorption and anti-fouling properties of the quartz stone plate during use, resulting in quality problems in the use of the quartz stone plate. The problem that the overall mechanical properties are greatly reduced

Abstract

The invention discloses a preparation method of an environment-friendly quartzite plate. Quartz sand and pigment are introduced into a ball mill to be mixed, wherein the ball mill has an Al2O3 lining.According to the preparation method of the environment-friendly quartzite plate, by means of a specific raw material mixing sequence, it can be avoided that in the mixing process of pigment, quartz sand and resin, agglomeration occurs among all the raw materials and the quality of the quartz stone plate is seriously affected; In addition, by controlling the pressing and curing conditions, the compactness of the prepared quartz stone plate can be improved to a certain extent, and therefore the problems that the prepared quartzite plate is insufficient in water absorption and antifouling property are solved. The quartz sand, the quartz powder, the tourmaline and the silica powder are compounded in the unsaturated polyester resin, so that the water absorption and antifouling property of thequartz stone plate are improved. And a stable cross-linked net-shaped body is formed, so that the deformation application range is greatly improved, and the overall mechanical property of the preparedquartzite plate is improved.

Description

technical field [0001] The invention relates to the technical field of quartz plates, in particular to a method for preparing environmentally friendly quartz plates. Background technique [0002] Quartz stone, usually what we call quartz stone is a new type of stone artificially synthesized by more than 90% of quartz crystal plus resin and other trace elements. It is pressed by special machines under certain physical and chemical conditions. It is a large-scale plate, and its main material is quartz. Quartz is a mineral that easily becomes liquid when heated or pressured. It is also a fairly common rock-forming mineral. It is found in all three types of rocks. Because it crystallizes the latest in igneous rocks, it usually lacks complete crystal faces. It is mostly filled among other rock-forming minerals that crystallized first. [0003] Referring to Chinese Patent Publication No. CN110330263A, a crack-resistant quartz stone plate is proposed, which is made of quartz ston...
