Abstract

The invention relates to a polypropylene antistatic composite material and a preparation method thereof, belonging to the technical field of polypropylene composite materials. The invention is characterized in that the polypropylene antistatic composite material contains conductive aluminum borate whiskers, and is AlB[w] / PP for short. The preparation method comprises the following steps: proportionally adding aluminum borate whiskers into distilled water, adding concentrated hydrochloric acid so that the acid concentration reaches 0.6-1.2 mol.L<-1>, proportionally adding tin tetrachloride and urea, heating the mixed liquor to 90-110 DEG C, reacting for 1-3 hours, filtering, washing to remove unreacted substances, drying the filter cake, and calcining to obtain conductive aluminum borate whiskers (AlB[w] for short); and proportionally mixing the AlB[w] and polypropylene, mixing, crushing, putting the mixture in a die, putting the die in a muffle furnace at 180-200 DEG C, keeping the temperature for 30-60 minutes, carrying out die forming in a flat vulcanizing machine, and depressurizing and stripping when the temperature of the die drops to below 60 DEG C, thereby obtaining the AlB[w] / PP.

Description

technical field [0001] The invention belongs to the technical field of polypropylene composite materials, and in particular relates to a polypropylene antistatic composite material and a preparation method thereof. Background technique [0002] During production, processing and use, polymers are often charged with static electricity when they come into contact with other materials and devices. For example, during the spinning process of polyacrylonitrile fibers, the static electricity generated by friction can reach more than 1500 volts. The accumulation of fiber stretching static electricity can even reach tens of thousands of volts. Generally speaking, static electricity is an unfavorable factor in the process of polymer processing and use, because static electricity hinders normal processing technology, static electricity damages product quality, and may even endanger personal and equipment safety. Due to the rich source of raw materials and the excellent characteristic...
