Problems solved by technology

At present, although there are some adhesives for conveyor belt repair on the domestic market, the existing adhesives for conveyor belt repair usually have the following disadvantages: 1. The adhesive is non-flame retardant, which has safety problems and cannot meet the requirements. Coal mine underground and other places; 2. The curing is slow at room temperature, and it needs to be heated to make it solidify quickly during use, and the construction is more complicated; 3. When repairing the damaged surface of the conveyor belt with repair strips or repair shee

Embodiment 1

[0039] The composition ratio of a flame retardant conveyor belt repair glue:

[0040]

[0041] The organic flame retardant is an environment-friendly halogen-free nitrogen and phosphorus compound intumescent flame retardant, and its model is Doher-6002A.

Embodiment 2

[0043] The composition ratio of a flame retardant conveyor belt repair glue:

[0044]

[0045]

[0046] The organic flame retardant is an environment-friendly halogen-free nitrogen and phosphorus compound intumescent flame retardant, and its model is Doher-6002A.

Embodiment 3

[0048] The composition ratio of a flame retardant conveyor belt repair glue:

[0049]

[0050] The organic flame retardant is an environment-friendly halogen-free nitrogen and phosphorus compound intumescent flame retardant, and its model is Doher-6002A.

[0051] Three kinds of embodiment preparation methods are identical, take embodiment 1 as example:

[0052] A. Put the solvent (trichloroethylene 90g, 1,2-dichloroethane 90g, toluene 30g) into the high-speed dispersion dynamic mixer, start stirring, and then add neoprene, tackifying resin (2402 resin, hydrogenated rosin resin) ), highly active magnesium oxide, anhydrous magnesium sulfate, organic flame retardant, antioxidant 264, stir for 6h-8h until the materials are evenly dispersed;

[0053] B. Add silane coupling agent KH550 and stir for 2 hours to 4 hours until the material is evenly dispersed to prepare a flame retardant conveyor belt repair glue.

Abstract

The invention discloses a flame-retardant conveyor belt repair adhesive. The adhesive comprises, by mass, 9.0-15.0% of chloroprene rubber, 5.0-15.0% of tackifying resin, 0.1-0.5% of high-activity magnesium oxide, 1.5-3.0% of an organic flame retardant, 0.3-0.6% of an inorganic moisture scavenger, 0.5-1.0% of an adhesion promoter, 73.5-83.5% of a solvent system and 0.1-1.0% of an antioxidant. The invention also provides a preparation method and a use method of the flame-retardant conveyor belt repair adhesive. The flame-retardant conveyor belt repair adhesive provided by the invention has high bonding strength, and can realize rapid cold vulcanization bonding; the adhesive is suitable for a conveyor belt joint lap joint repairing process and matched with a repairing strip to repair the surface of a conveyor belt; and the adhesive has certain flame-retardant capability, can realize self-extinguishing after being away from fire, and meets the requirements of places such as underground coal mines and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a flame-retardant conveyor belt repair adhesive and a preparation method and application method thereof. Background technique [0002] As one of the means of transportation and delivery, rubber conveyor belts are widely and massively used in coal mines, steel, power plants, ports, mines, cement plants and other places. Most of the rubber conveyor belts are run in the open environment. Among them, the conditions of use in metallurgical mining, non-ferrous metals, coal and other industries are the worst. Therefore, longitudinal tearing, edge tearing, hole punching, fracture, surface damage, etc. often occur, and need to be repaired and replaced in time. [0003] When repairing the rubber conveyor belt, the cold bonding method is generally used, that is, the adhesive is used to repair the conveyor belt at room temperature. The use of adhesives to repair rubber conve...
