Problems solved by technology

[0002] At present, conveyor belts are widely used in various industries. In chemical plants, paper mills and other factories and mines, the requirements for conveyor belts are getting higher and higher. The acid and alkali resistance is not good, which will easily lead to corrosion and aging of the covering layer, resulting in the aging and cracking of the covering rubber of the belt, and the separation of the rubber layer and the core layer of the belt, resulting in a shortened service life of the belt

[0028] The preparation method of the above-mentioned flame retardant acid and alkali resistant conveyor belt covering rubber comprises the following steps:

[0029] (1) Add neoprene CR322 rubber, natural rubber, butadiene BR9000 rubber to the internal mixer for pre-compression mixing for 30-60 seconds;

[0030] (2) Then add anti-aging agent RD, anti-aging agent 4010NA, zinc oxide, magnesium oxide, stearic acid, mododele 985P, chlorinated polyethylene CPE135, N220 carbon black, N330 carbon black, ultra-fine barium sulfate, dioxide Antimony, chlorinated paraffin 70, zinc borate and accelerator DM are mixed for 30-70 seconds;

[0031] (3) Then add N220 carbon black, N330 carbon black and mix for 30-70 seconds;

[0032] (4) When banburying until the temperature of the mixed material reaches 120-130°C, the rubber is discharged to obtain a section of mixed rubber;

[0033] (5) After the rubber compound in step (4) is cooled and parked for 5-16 hours, then add it to the internal mi...

Abstract

The invention provides antiflaming acid-alkali resistant conveyer belt covering glue which is prepared from the following components in parts by weight: 70 parts of neoprene CR 322, 20 parts of natural rubber, 10 parts of butadiene rubber 9000, 1-2 parts of an antiager RD, 1-3 parts of an antiager 4010 NA, 4-8 parts of zinc oxide, 2-8 parts of magnesium oxide, 1-3 parts of stearic acid, 1-3 parts of mold cleaner 985 P, 5-20 parts of chlorinated polyethylene CPE 135, 15-50 parts of N 220 carbon black, 10-30 parts of N 330 carbon black, 1-4 parts of sulphur, 10-30 parts of superfine barium sulfate, 4-8 parts of antimonous oxide, 10-30 parts of chlorinated paraffin 70, 5-20 parts of zinc borate and 1-3 parts of an accelerant DM. The invention further provides a preparation method of the antiflaming acid-alkali resistant conveyer belt covering glue. The antiflaming acid-alkali resistant conveyer belt covering glue has the advantages of being corrosion resistant and unlikely to age and chap during the transportation process, excellent in abrasion resistance and tearing property, and long in service life.

Description

technical field [0001] The invention relates to the field of conveyor belts, in particular to a flame retardant, acid and alkali resistant conveyor belt covering glue and a preparation method thereof. Background technique [0002] At present, conveyor belts are widely used in various industries. In chemical plants, paper mills and other factories and mines, the requirements for conveyor belts are getting higher and higher. Poor acid and alkali resistance can easily lead to corrosion and aging of the covering layer, resulting in the aging and cracking of the covering rubber of the belt, and the separation of the rubber layer and the core layer of the belt, resulting in a shortened service life of the belt. Therefore, it is necessary to further improve the conveyor belt covering glue. Contents of the invention [0003] The object of the present invention is to provide a flame retardant acid and alkali resistant conveyor belt covering glue with good acid and alkali resistanc...
