Description
Technical Field
The invention belongs to the technical field of flame-retardant adhesives, and particularly relates to a high-elongation high-adhesion flame-retardant intermediate adhesive for a steel wire rope conveyer belt, and a preparation method and application thereof.
Background
The underground coal mine has very strict requirements on the flame retardant property of the conveyer belt, and the requirements on the combustion test of the alcohol burner by the MT/T668-2019 standard are as follows: for 6 test pieces with complete covering layers, after the blast burner is removed, the arithmetic average value of the flame burning time and the arithmetic average value of the flameless burning time of all the test pieces are not more than 3.0s, wherein the single value of the flame burning time and the flameless burning time of each test piece is not more than 10.0s; for 6 test pieces with the coating removed, the arithmetic average of the flame burning time and the arithmetic average of the flameless burning time of all the test pieces are not more than 5.0s after the blast lamp is removed, wherein the single value of the flame burning time and the flameless burning time of each test piece is not more than 15.0s. The intermediate rubber of the steel wire rope conveyer belt is generally composed of natural rubber, styrene-butadiene rubber and butadiene rubber, the oxygen index of the three rubbers is between 19 and 21, the oxygen index is low, the decomposition temperature is low, and combustion is easy to occur. The formula of the high-flame-retardance steel wire rope core intermediate adhesive meeting the MT/T668-2019 standard is designed, a large amount of flame retardant is required to be added, and the adhesive property of the intermediate adhesive and the steel wire rope can be reduced due to the addition of the large amount of flame retardant.
To solve this problem, it is common to use a plurality of adhesives in combination to improve the adhesion effect. Among them, cobalt salt bonding systems and meta-white bonding systems are the most common, and an indispensable bonding agent is magnesium oxide, but the addition of magnesium oxide greatly reduces the elongation of the vulcanized rubber. When the common tackifier is used for plasticizing and adjusting the elongation, the free radical of the flame retardant is generally combined with the double bond of aromatic hydrocarbon, so that the adhesive resin is invalid, the self-adhesive force of rubber is reduced, the efficiency is low, and the flame retardance and the physical properties are not facilitated.

mixing natural rubber and styrene-butadiene rubber for 35-45 s, adding a vulcanization activator, an anti-aging agent, antimony trioxide, magnesium oxide, cobalt boronoyl, aluminum silicate, ammonium polyphosphate, zinc borate, an adhesive RS and tackifying resin, mixing for 85-95 s, adding carbon black, white carbon black and chlorinated paraffin, and discharging at 125-135 ℃ to obtain a section of rubber;
and (3) standing the first section of glue for 7-9 hours, adding a vulcanizing agent, an accelerator and an adhesive A, mixing, and discharging glue at the temperature of 95-105 ℃ to obtain the high-elongation high-adhesion steel wire rope conveyer belt flame-retardant intermediate glue.
8. The steel wire rope core conveyer belt is characterized by comprising a steel wire rope, a flame-retardant intermediate adhesive for wrapping the steel wire rope and a covering adhesive for covering the flame-retardant intermediate adhesive;
the flame-retardant intermediate adhesive is the high-elongation high-adhesion steel wire rope conveyer belt flame-retardant intermediate adhesive prepared by the preparation method of any one of claims 1-6 or the high-elongation high-adhesion steel wire rope conveyer belt flame-retardant intermediate adhesive prepared by the preparation method of claim 7.
