Problems solved by technology

At present, most of the conveyor belts in underground coal mines use halogen-containing flame retardant systems such as chlorinated paraffin. Once this kind of conveyor belt catches fire and burns the conveyor belt, the combustion of the conveyor belt will easily release a large amount of irritating smoke and harmful substances.

Embodiment 1

[0021] Example 1: A low-smoke, low-halogen, flame-retardant conveyor belt covering rubber for coal mines. The chemical composition and mass percentage of the covering rubber are as follows: natural standard rubber: 0-50 parts, styrene-butadiene rubber SBR1502: 20-80 parts, Butadiene BR9000 rubber: 0-40 parts, polyisobutylene PB1300: 0-10 parts, anti-aging agent: 3-6 parts, zinc oxide: 4-8 parts, magnesium oxide: 0-3 parts, stearic acid: 0-2 parts Parts, flow release agent: 1-3 parts, N234 carbon black: 30-50 parts, nano aluminum hydroxide: 10-20 parts, antimony trioxide: 4-8 parts, decabromodiphenylethane: 5- 15 parts, composite ceramic powder: 5-20 parts, intumescent halogen-free flame retardant IFR: 5-15 parts, multi-purpose synergistic halogen-free flame retardant PNA220: 5-15 parts, smoke suppressant molybdenum salt: 2 -8 parts, Accelerator: 0-7 parts, Sulfur: 0-3 parts.

[0022] The chemical composition and content of the cover rubber in this embodiment are selected as f...

Embodiment 2

[0029] Example 2: A low-smoke, low-halogen, flame-retardant conveyor belt covering rubber for coal mines. The chemical composition and content of the covering rubber are selected as follows: styrene-butadiene rubber SBR1502: 70kg, butadiene-butadiene BR9000 rubber: 30kg, polyisobutylene PB1300: 10kg, Antiaging agent: 3kg, zinc oxide: 6kg, magnesium oxide: 1kg, stearic acid: 1kg, flow release agent: 1kg, N234 carbon black: 40kg, nano aluminum hydroxide: 15kg, antimony trioxide: 6kg, decabromine Diphenylethane: 15kg, composite ceramic powder: 10kg, intumescent halogen-free flame retardant IFR: 10kg, multi-purpose synergistic halogen-free flame retardant PNA220: 13kg, smoke suppressant molybdenum salt: 5kg, accelerator: 3.2 kg, sulfur: 3kg.

[0030] Wherein, the smoke suppressant molybdenum salt is a mixture of molybdenum trioxide and ammonium octamolybdate, and the anti-aging agent is a mixture of anti-aging agent RD, anti-aging agent 4010NA, and anti-aging agent 4020, and the a...

Abstract

The invention discloses low-smoke low-halogen flame-retardant conveyor belt covering glue for a coal mine, and relates to the technical field of conveyor belt covering glue. The covering glue comprises the following chemical components: natural standard rubber, styrene-butadiene rubber SBR1502, cis-butyl BR9000 rubber, polyisobutylene PB1300, an anti-aging agent, zinc oxide, magnesium oxide, stearic acid, a flow release agent, N234 carbon black, nano-aluminum hydroxide, antimony trioxide, decabromodiphenylethane, composite ceramic powder, expanded halogen-free flame-retardant IFR, a multi-purpose synergistic halogen-free flame retardant PNA220, molybdenum salt used as a smoke suppressant, an accelerator and sulfur. The low-smoke low-halogen flame-retardant conveyor belt covering glue disclosed by the invention is used under a coal mine well to meet flame-retardant performance of the conveyor belt, has excellent wear resistance and flame retardancy, and is low in smoke amount and smoketoxicity.

Description

technical field [0001] The invention relates to the technical field of conveyor belt covering glue, in particular to a low-smoke, low-halogen, flame-retardant conveyor belt covering glue for coal mines and a preparation process thereof. Background technique [0002] Conveyor belts used in underground coal mines are used in the explosion-hazardous environment of underground coal mines, so the conveyor belts must have high flame retardant and antistatic properties. At present, most of the conveyor belts in underground coal mines use halogen-containing flame retardant systems such as chlorinated paraffin. Once this kind of conveyor belt catches fire and burns the conveyor belt, the combustion of the conveyor belt will easily release a large amount of irritating smoke and harmful substances. . When a fire accident occurs, only a small number of people are directly burned to death, and most of them are suffocated to death by the toxic smoke produced after burning. Because the c...
