Application number/patent number: 200410066442
The present invention relates to a flame-retardant and antistatic plastic woven bag. The technical problem to be solved by the present invention is to provide a flame-retardant and antistatic plastic woven bag whose arithmetic average surface resistance is much lower than the national standard value. The technical solution to this problem is: the formula and process of the woven bag are: a) First, mix 50-200 parts by weight of antimony trioxide and 100 parts by weight of polypropylene to form a flame-retardant masterbatch A; b), mix ten parts by weight. 50 to 200 parts by weight of brominated diphenyl ether and 100 parts by weight of polypropylene are mixed and plasticized to form a flame retardant masterbatch B; c), 1 to 50 parts by weight of an electrostatic agent and 100 parts by weight of polypropylene are mixed and plasticized to form an antistatic masterbatch; d ), then mix 1 to 100 parts by weight of flame retardant masterbatch A and flame retardant masterbatch B, 1 to 50 parts by weight of antistatic masterbatch, and 100 parts by weight of polypropylene in a high-speed mixer; e), plasticize Machine-drawn into a film, then drawn into silk, and wound into a silk reel; f), use the silk reel to weave bags; g), and finally use a homemade electrostatic agent for surface treatment. The invention can be used in coal mines, chemical industries, etc.
