Problems solved by technology

[0004] Cast stone slabs are not only wear-resistant during use, but also to resist the impact of materials to a greater extent. Because the surface of the existing cast slate slabs is smooth, the cement mortar is not firmly pasted, and even the use of cement cannot guarantee the bonding strength, so often When the material impacts, the cast stone plate breaks and falls off, which affects the use effect, requires a lot of maintenance, has a short service life, wastes resources and other technical defects

Abstract

The invention discloses a composite foam basalt cast stone slab and a preparation process thereof. The preparation process comprises the following steps: (1) preparing a base material and auxiliary materials as raw materials for producing cast stone slabs; (2) cutting the foam basalt into the required size, put into the mold and heat to 500-600°C; (3) melt the raw materials for producing cast stone slabs at high temperature and pour the melted cast stone magma onto the foam basalt surface in the mold; (4) cast stone magma After the surface is solidified, demoulding is performed to obtain a composite board, and the composite board is crystallized and annealed to obtain a composite foam basalt cast stone board. The impact resistance of the cast stone plate can be improved by adopting the preparation process, and the bonding strength of the cast stone plate can be enhanced, and the cast stone plate has the characteristics of high temperature resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of production of building materials, in particular to a composite foam basalt cast stone plate and a preparation process thereof. Background technique [0002] Cast stone slabs are made of natural rock diabase, basalt, shale or industrial waste as raw materials, adding certain additives such as amphibolite, dolomite, fluorite and crystallization agents such as chromite, titanium magnesium ore, etc. after melting, A non-metallic anti-corrosion and wear-resistant material processed by casting, crystallization and annealing. [0003] Foamed basalt is processed into powder by using basalt, mixed with part of slag as the main raw material, added foaming agent, modifier, accelerator, etc., crushed and evenly mixed into a batch, placed in a specific mold and melted at 1100 ° C to 1200 ° C A porous basalt material filled with numerous uniform bubbles formed by , foaming and annealing. The bubbles in the basalt acc...
