Composite floor brick prepared from modified carbide slag and waste polyvinyl chloride plastics

Abstract

The invention discloses a composite floor brick prepared from modified carbide slag and waste polyvinyl chloride plastics and a production method thereof, and the composite floor brick is prepared by hot pressing after mixing of the modified carbide slag and the waste polyvinyl chloride plastics according to a certain weight ratio. The composite floor brick is prepared by adopting the waste plastics and industrial waste residue carbide slag as main raw materials and using an appropriate preparation method, so that environmental pollution of the waste polyvinyl chloride plastics and the carbide slag can be reduced, and a new material for construction engineering is provided. The composite floor brick product has the advantages of simple production process, low price, water resistance and skid resistance, heat conduction and warmth keeping, good sound absorption, excellent foot-feel comfortable degree and the like, and has good social benefits and market prospects. According to the composite floor brick, through modification of the carbide slag surface by use of a coupling agent distearoyl isopropoxy aluminate, the surface property of the carbide slag is changed into lipophilic from hydrophilic, so that the blending compatibility and associative property of the carbide slag and the waste polyvinyl chloride plastics are greatly improved, and the performances of the composite floor brick are improved.

Description

Technical field [0001] The invention belongs to the field of building materials, and relates to a floor tile that can be widely used for laying on the ground in places such as public places and family residences, in particular to a composite floor tile made of modified calcium carbide slag and waste polyvinyl chloride plastic and the same The production method also relates to a modified calcium carbide slag used as a waste polyvinyl chloride plastic filler and a preparation method thereof. Background technique [0002] At present, the industrial waste calcium carbide slag discharged by the chemical industry in my country each year is increasing year by year. In addition to the production of calcium carbide slag bricks, gypsum, cement, and bleaching solution, these calcium carbide slags are also piled up in the ash storage yards of calcium carbide slag. If the land is lost, it will also cause serious environmental pollution. In addition, with the increasing production and consumpt...

Problems solved by technology

At the same time, most of the floor tiles currently used for laying on the ground in public places and family houses are made of clay, porcelain clay, and stone. The production process is complicated and the price is high. There are still some defects in this aspect, and a new type of material that uses waste, reduces pollution, and saves resources is urgently needed to solve the problem

On the other hand, in the blending process of waste polyvinyl chloride plastics and carbide slag, because carbide slag is a polar inorganic substance and hydrophilic, while waste polyvinyl chloride plastic is a non-polar organic substance and lipophilic, the physical shape and The chemical structure is very different, so that there is a lack of chemical bonding between the two, resulting in uneven dispersion of inorganic fillers in the above-mentioned organic matter during two-phase blending, and poor compatibility between the two phases, thus affecting the performance of composite floor tiles
