Tea saponin modified red mud and composite floor tile made from red mud and waste plastics

Abstract

The invention discloses tea saponin modified red mud which comprises 7-13wt% of tea saponin and 87-93wt% of red mud. The tea saponin modified red mud is made by the following steps: adding red mud and tea saponin into a high-speed mixer at the temperature of 50 DEG C, stirring for 7-9 minutes, thereby obtaining the tea saponin modified red mud. The composite floor tile made from the tea saponin modified red mud and waste polydiphenyl ether plastics is made from the following raw materials in parts by weight: 14-25 parts of waste polydiphenyl ether plastics and 75-86 parts of tea saponin modified red mud. The making method of the composite floor tile comprises the following steps: drying, stirring by a stirrer, plastifying into sheets, performing mold pressing, cutting, thereby obtaining the composite floor tile. The surface property of the red mud is changed from hydrophilic to oleophilic by utilizing the tea saponin, so that the blending compatibility between the red mud and waste polydiphenyl ether and the binding property are greatly improved, and the performance of the composite floor tile is greatly improved. Meanwhile, the filling fraction of the red mud in the composite floor tile is increased, and the cost of the product is effectively reduced.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to tea saponin modified red mud used as waste polyphenylene ether plastic filler and a composite floor tile made of waste polyphenylene ether plastic. Background technique [0002] At present, the industrial waste residue red mud discharged by my country's chemical industry is increasing year by year. In addition to the production of red mud bricks and cement, there are many ash storage yards stacked in red mud, which not only invades the land, but also cause serious environmental pollution. In addition, with the increasing production capacity and consumption of polyphenylene ether plastics in my country, the output of plastic waste formed by discarded polyphenylene ether plastics is increasing, causing serious "white pollution". In addition, the floor tiles currently used for laying the ground in public places and family houses are mostly made of clay, porcelain clay, ...

Problems solved by technology

[0002] At present, the industrial waste residue red mud discharged by my country's chemical industry is increasing year by year. In addition to the production of red mud bricks and cement, there are many ash storage yards stacked in red mud, which not only invades the land, but also cause serious environmental pollution

In addition, with the increasing production capacity and consumption of polyphenylene ether plastics in my country, the output of plastic waste formed by discarded polyphenylene ether plastics is increasing, causing serious "white pollution"

In addition, 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 the degree of improvement, and a new 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 polyphenylene ether plastic and red mud, red mud is a polar inorganic substance and hydrophilic, while waste polyphenylene ether plastic is a non-polar organic substance and lipophilic. 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
