Abstract
The invention relates to a production method for a nitrile butadiene rubber adhesive, and a product produced by the production method is an adhesive with good performance. The nitrile butadiene rubber adhesive is generally produced from nitrile butadiene rubber with high acrylonitrile content, phenolic resin, a complexing agent and a solvent through a certain process. The nitrile butadiene rubber adhesive has the advantages of high adhesive strength, wide application range, high heat resistance and high oil resistance, and can be used for the adhesion of aluminum, stainless steel, fiber processing products for aircrafts, friction plates of brake blocks, large-sized coated fiber products, etc. The raw materials for producing the adhesive comprises: nitrile butadiene rubber containing 40% of acrylonitrile, dichloroethane, toluene, carbon black, chlorinated poly(vinyl chloride) resin, coumarone resin, carbon bisulfide, sulfur, zinc oxide, phenolic resin, cyclohexylamine and dibenzothiazole disulfide.
Description
Affiliated technical field:
Product of the present invention belongs to chemical field
Background technology:
Paracril is tawny or yellow banded elastomerics, non-polar solvent performances such as anti-gasoline and aliphatic hydrocarbon are good, in various degree expansion and dissolving are arranged in chlorinated solvents, lipid equal solvent, wear resistance and thermotolerance are better, winter hardiness, elasticity are relatively poor, because paracril is very strong to the hydrophilic substance tackiness, is highly suitable for doing tackiness agent.Product of the present invention is to be the tackiness agent of base-material with the paracril, and this class tackiness agent adds different resins in order to improve bonding strength or other composition carries out modification, resin that can add such as resol, Resins, epoxy, polyvinyl chloride (PVC) RESINS etc.In the paracril synvaren, resol is used manyly more, and bonding strength is big more, and tackiness agent is then crisp more.When preparation butyronitrile modified phenolic adhesive, acrylonitrile content in the rubber is high more, just strong more with the mating capability of resol, in paracril, acrylonitrile content generally can not be lower than 30%, can not be higher than 40%, and the rubber of high acrylonitrile content can be produced the tackiness agent of fine adhesiveproperties and glue film performance, and the rubber of low acrylonitrile content can be produced the tackiness agent with better low-temperature performance, can regulate the content of vinyl cyanide as required between 30%-40%.The butyronitrile modified phenolic adhesive normally is made up of paracril, resol, Synergist S-421 95 and the solvent of high acrylonitrile content, with paracril is the tackiness agent that major ingredient is produced, the cohesive strength height, wide application, have good thermotolerance, oil-proofness, can be used for aluminium, not single steel, aircraft with fiber process goods, the friction plate of brake facing, large-scale spread goods, as the bonding of canvas, nylon cloth, woven fiber glass or paracril and other material.
Summary of the invention:
Produce the nitrile rubber adhesive of different purposes, use different prescriptions, the invention provides a kind of is the method that base-material is produced tackiness agent with paracril, and its product is mainly used in aluminium, not single steel, aircraft fiber process goods, the friction plate of brake facing, the bonding of large-scale spread goods.The raw material of producing this tackiness agent use has: 1. 25 parts of the paracrils (major ingredient) that contain 40% vinyl cyanide; 2. ethylene dichloride is 200 parts; 3. toluene is 20 parts; 4. carbon black is 12 parts; 5. supervinyi chloride resin is 5 parts; 6. coumarone indene resin is 3 parts; 7. dithiocarbonic anhydride is 3 parts; 8. sulphur is 1 part; 9. zinc oxide is 18 parts; 10. resol is 4 parts; 11. 3 parts of hexahydroaniline; 12. the curing dibenzo is frustrated 6 parts.
The beneficial effect of product of the present invention is: this adhesive bonds intensity height, wide application, have good thermotolerance, oil-proofness, can be used for aluminium, not single steel, aircraft with fiber process goods, the friction plate of brake facing, large-scale spread goods, as the bonding of canvas, nylon cloth, woven fiber glass or paracril and other material.
