Nitrile rubber adhesive structure, composition and characteristicsNitrile Rubber is a copolymer of butadiene and acrylic wax emulsion polymerization, which has excellent oil resistance. Because it contains polar Nitrile base, so it has good adhesive properties, high tensile strength, and is resistant to polar polymers The substance has good compatibility, and the content of nitrile The properties have an obvious impact. Currently, propylenenitrile is generally used as an adhesive.Copolymer with a content of 30%~40%.
DingNitrileRubber adhesive is based on nitrilenitrilerubber. In order to improve the adhesion To improve the composite strength, modified resins such as modified phenolic resin, alkyd resin, polyvinyl chloride resin, etc. can be added. In order to improve the adhesion with metal, chlorinated rubber can be added. In order to improve adhesion, diesters, rosin gum or coumarone resin can also be used; in order to increase softness and cold resistance. Dibutyl phthalate, tricresyl phosphate, etc. can be used; antioxidants such as trimethyldihydroquinoline can ensure the stability of the solution. At the same time, it can also improve the adhesion and heat resistance and improve the stability of the polymer. , then a mixture of phenylsulfanine and phenyl-p-phenylenediamine can be used;Carbon black as filler. It can increase strength and adhesion; acetone, methyl ethyl ketone, dichloroethane, etc., which are the most easily soluble in rubber, can be used as solvents, and can also be mixed with ethyl acetate, xylene, etc.
DingNitrileRubber has the following characteristics:
①Due to its excellent oil resistance, it can be used to bond soft PVC plastic materials with a large amount of plasticizer migration that are usually difficult to bond;
② After appropriate modification, it can be widely bonded to various adherends and has high bonding strength;
③Has a certain degree of heat resistance.
But it also has the following weaknesses:
①Easy to change color when exposed to heat and light;
②The price is higher than other solvent-based rubber adhesives. DingEye rubber adhesive is suitable for bonding various materials such as metal, plastic, synthetic rubber, wood, fabric and leather , especially suitable for bonding soft PVC materials such as PVC sheets, PVC foam, PVC fabrics, etc. ExampleSuch as polychloride Vinyl floor pasting, polyvinyl chloride and metal, wood, hardboard and other composite materials.
