Abstract

The invention discloses a modified aluminum borate whisker, which is composed of 0.5-2wt% coupling agent, 1.5-4wt% liquid paraffin and 95%-98wt% aluminum borate whisker, which is produced according to the following steps: a. Stir the coupling agent and liquid paraffin with a mixer for 3 to 4 minutes at 20°C to obtain a coupling agent dilution; b. Add aluminum borate whiskers to a high-speed mixer, heat and stir, and add the coupling agent at 80°C agent diluent, mixed for 5 to 10 minutes to obtain modified aluminum borate whiskers; the composite floor tiles made of it and waste plastics are made of the following raw materials in parts by weight: 20 to 40 parts of waste polyethylene plastics, 20 to 40 parts of waste polypropylene 20-50 parts of plastic, 30-50 parts of modified aluminum borate whiskers. The invention changes the surface properties of the aluminum borate whiskers from hydrophilic to lipophilic, greatly improves the blending compatibility and combination with waste polyethylene and polypropylene, and has good market prospects.

Description

technical field

[0001] The invention belongs to the field of building materials, in particular to a modified aluminum borate whisker used as a filler for waste polyethylene and polypropylene plastics and a composite floor tile made of waste plastics. Background technique

[0002] At present, the floor tiles used in public places and family residences are mostly made of clay, porcelain clay, and stone. The production process is complicated and the price is high. There are still some defects, and a new material for waste utilization, pollution reduction and resource saving is urgently needed to solve the problem. On the other hand, in the blending process of waste polyethylene, polypropylene plastics and aluminum borate whiskers, aluminum borate whiskers are polar inorganic substances and hydrophilic, while waste polyethylene and polypropylene plastics are non-polar organic substances, hydrophilic Oily, the physical shape and chemical structure of the two are very different, ...
