Problems solved by technology

However, due to the small Mohs hardness of calcium carbonate and broken glass, and poor acid and alkali resistance, the surface hardness of the stone is small and easy to wear; and the acid and alkali resistance is poor
[0004] On the other hand, for the artificial stone production process, it is generally mixed, clothed, vibrated, heated and solidified, and then flattened and polished; among them, the scraped and thickened surface is mainly scraped off the surface of the artificial stone plate by a scraper. In order to improve the flatness, in the process of scraping and thickness determination, it is necessary to remove 1.5 ~ 5mm of the plate, wasting a lot of raw materials
At the same time, after the thickness is leveled, the surface roughness is relatively high. It is necessary to use diamond grinding blocks, stone grinding blocks and fiber grinding blocks to polish the artificial stone plate in turn. A large amount of tap water is required during the polishing process, resulting in waste of tap water; , Among the waste materials generated in the process of scraping and thickness setting, because the resin has been cured, it is difficult to regenerate, so it is also difficult to reuse

preparation example Construction

[0044] see figure 1 , the present invention provides a kind of preparation method of artificial stone plate, it comprises:

[0045] S1: Mix all kinds of artificial stone slab raw materials evenly to obtain a mixture;

[0046] Specifically, the raw materials of the artificial stone slabs include silicone oil, which can effectively promote the flow of aggregates during the vibration process, and promote the compaction and flattening of the loose body; The surface of the stone slab body has high flatness, no need for scraping and thickness determination, only a small amount of polishing is required. It avoids wasting a lot of raw materials and water resources in the polishing process, and is energy-saving and environmentally friendly. In addition, silicone oil can be coated on the surface of the aggregate to reduce the surface tension of the aggregate, form a protective layer, and reduce the adsorption of the aggregate to the resin. Therefore, silicone oil plays the role of re...

Abstract

The invention discloses a preparation method of an artificial stone plate, which comprises the steps of mixing, fabricating and vibrating the artificial stone plate raw materials to obtain a compact body, heating and solidifying the compact body to obtain a plate body; polishing the plate body, The finished artificial stone plate is obtained; wherein, in the polishing process, the plate blank is polished by using stone grinding blocks and / or resin grinding blocks and / or fiber grinding blocks; wherein, the formula includes 0.8-3wt% of silicone oil. Correspondingly, the present invention also discloses an artificial stone plate. In the present invention, silicone oil is introduced into the formula, which can effectively promote the flow of the aggregate during the vibration compaction process, and promote the densification and leveling of the loose body; The flatness is high, only a small amount of polishing is required, and there is no need to scrape and fix the thickness, which reduces the waste of a lot of raw materials in the process of scraping and determining the thickness, and reduces the cost of raw materials.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing an artificial stone plate and the artificial stone plate. Background technique [0002] The existing artificial stone slabs can be divided into two types: artificial quartz slabs and artificial granite (calcium carbonate+resin). Among them, although artificial granite is cheap, its chemical resistance is poor, so its application range is narrow. The artificial quartz stone has excellent mechanical properties and chemical resistance, and is widely used. Artificial quartz stones are generally made of quartz stones of different particle sizes, resins, coupling agents, curing agents, etc. However, the existing artificial quartz stones use a relatively high amount of resin, resulting in high raw material costs and high VOC emissions during the production process. Moreover, existing artificial quartz stones use natural quartz as raw material, but na...
