Tea saponin modified blast furnace slag and composite floor brick prepared from tea saponin modified blast furnace slag and waste plastic

Abstract

The invention discloses tea saponin modified blast furnace slag which is prepared from 7-12wt% of tea saponin and 88%-93wt% of blast furnace slag. A preparation method for the tea saponin modified blast furnace slag comprises the following steps: adding the blast furnace slag and the tea saponin into a high-speed mixer at a temperature of 70 DEG C, and stirring for 7-9 minutes to obtain the tea saponin modified blast furnace slag. A composite floor brick prepared from the tea saponin modified blast furnace slag and waste polyformaldehyde plastic is prepared from the following raw materials in parts by weight: 15-20 parts of waste polyformaldehyde plastic and 80-85 parts of the tea saponin modified blast furnace slag; and the raw materials are dried, are stirred by a stirrer, are plastified into sheets, are subjected to mould pressing and are cut into sheets, so that the composite floor brick is formed. The surface property of the blast furnace slag is changed into lipophilicity from hydrophily through tea saponin, so that the co-blending compatibility and associativity of the blast furnace slag and the waste polyformaldehyde are improved greatly, and therefore, performances of the composite floor brick are improved greatly; and meanwhile, filling fraction of the blast furnace slag in the composite floor brick is increased, so that product cost is effectively reduced.

Description

Technical field [0001] The invention belongs to the field of building materials, and specifically relates to a tea saponin-modified blast furnace slag used as a filler for waste polyformaldehyde plastic and a composite floor tile made of it and waste polyformaldehyde plastic. Background technique [0002] At present, the amount of industrial waste blast furnace slag discharged by my country's chemical industry is increasing year by year. In addition to being mostly used to produce blast furnace slag bricks and cement, these blast furnace slags are also piled in many blast furnace slag ash storage yards. Not only do they occupy land, they also cause Cause serious environmental pollution. In addition, with the increasing production capacity and consumption of polyoxymethylene plastics in our country, the output of plastic waste formed by discarded polyoxymethylene plastics is increasing, causing serious "white pollution". In addition, the floor tiles currently used in public p...

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 polyoxymethylene plastics and blast furnace slag, because blast furnace slag is a polar inorganic substance and hydrophilic, while waste polyoxymethylene plastic is a non-polar organic substance and lipophilic, the physical shape and chemical structure of the two The upper pole is 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 of the two phases, thus affecting the performance of composite floor tiles
