Tea saponin modified electrolytic manganese residues and compound flooring tile prepared from tea saponin modified electrolytic manganese residues and waste plastics

Abstract

The invention discloses tea saponin modified electrolytic manganese residues. The tea saponin modified electrolytic manganese residues are characterized by comprising 5wt%-7wt% of tea saponin, 2wt%-5wt% of NaOH and 88wt%-93wt% of electrolytic manganese residues. The tea saponin modified electrolytic manganese residues are prepared through the following steps: the electrolytic manganese residues and NaOH are added to a high-speed mixer at 25 DEG C and stirred for 6-7 min, tea saponin is added when the temperature reaches 65 DEG C, the mixture is heated and stirred for 5-6 min, and the tea saponin modified electrolytic manganese residues are obtained. A compound flooring tile prepared from the tea saponin modified electrolytic manganese residues and waste plastics is prepared from raw materials in parts by weight as follows: 20-30 parts of waste polyvinyl chloride plastics and 70-80 parts of the tea saponin modified electrolytic manganese residues through stirring, plastication into sheets, die pressing and cutting into sheets. The surface property of the modified electrolytic manganese residues is changed from hydrophilicity to lipophilicity by means of tea saponin, blending compatibility and binding performance of the modified electrolytic manganese residues with waste polyvinyl chloride are improved greatly, the performance of the compound flooring tile is improved greatly, filling parts of the electrolytic manganese residues in the compound flooring tile are increased, and product cost is reduced effectively.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to tea saponin modified electrolytic manganese slag used as waste polyvinyl chloride plastic filler and a composite floor tile made of waste polyvinyl chloride plastic. Background technique [0002] At present, the industrial waste electrolytic manganese slag discharged by my country's chemical industry is increasing year by year. These electrolytic manganese slags are not only used to produce electrolytic manganese slag bricks and cement, but also many ash storage yards are stacked in electrolytic manganese slag. land, but also cause serious environmental pollution. In addition, with the increasing production capacity and consumption of polyvinyl chloride plastics in my country, the output of plastic waste formed by discarded polyvinyl chloride plastics is increasing, causing serious "white pollution". In addition, the floor tiles currently used for laying the ground i...

Problems solved by technology

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 polyvinyl chloride plastics and electrolytic manganese slag, electrolytic manganese slag is a polar inorganic substance and is hydrophilic, while waste and old polyvinyl chloride plastic is a non-polar organic substance and is lipophilic. The shape and chemical structure are 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
