Method for preparing light composite artificial stone profile by using yellow phosphorus slags

Abstract

The invention provides a method for preparing a light composite artificial stone profile by using yellow phosphorus slags, which comprises the following steps of: S1. preparing a pore base layer, uniformly mixing silica powder and limestone granules, uniformly arranging the silica powder and the limestone granules at the bottom of a base layer forming die, pouring the yellow phosphorus slags intothe base layer forming die, and carrying out heat preservation, cooling and cutting processes to obtain a pore base layerprofile;S2. preparing a surface layer and forming thelight composite artificialstone profile, mixing and stirring an adhesive, natural stone granules or powder materials and inorganic mineral pigments to obtain a mixture, placing the pore base layer profile at the bottom of anartificial stone forming die, injecting the mixture into the artificial stone forming die, and uniformly coatingon the surface of the pore base layer profilewith the mixture through a composite process to form the surface layer;finally, preparing the light composite artificial stone profile through the working procedures of curing, demoulding and polishing.The method for preparing the light composite artificial stone profile by using the yellow phosphorus slags has the beneficial effects that the specific gravity of the pore base layer profile is reduced, the content of residual free calcium oxide and magnesium oxide in the yellow phosphorus slags is reduced, and the yellow phosphorus slagsarechanged into valuable.

Description

technical field [0001] The invention relates to the technical fields of metallurgy, chemical industry and building materials, in particular to a method for preparing light composite artificial stone profiles by using yellow phosphorus slag. Background technique [0002] Artificial stone is made of high molecular polymer or cement or a mixture of the two as a binder, with natural stone fragments and / or natural quartz stone or aluminum hydroxide powder as the main raw material, adding pigments and other auxiliary agents, and mixing and stirring , Condensation and curing processes such as composite material. It mainly includes artificial stone solid fabrics, artificial stone quartz stone and artificial stone granite and other products. According to the composition of the binder, it can be divided into three categories: organic, inorganic and organic-inorganic composite artificial stone. [0003] Organic artificial stone is made of crushed stone, stone powder, etc. as the basi...

Problems solved by technology

Most of the existing yellow phosphorus electric furnaces use molten slag to flow out intermittently. After the ferrophosphorus is settled, the molten slag at 1200-1450°C flows into the water quenching pool for water quenching to obtain water quenching slag. Steam, causing serious environmental pollution and visual pollution
