A kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, is related to a kind of vulcanization of rubber adhesive, and described adhesive is made of following components in percentage by weight：Halogenated rubber 1-2%；Isocyanates 18-22%；Epoxy resin 9-12%；Balance of solvent.Or adhesive is made of following components in percentage by weight：Halogenated rubber 0.5-2.5%；Isocyanates 15-25%；Epoxy resin 7-15%；Balance of solvent.The adhesive of the present invention is free of nitroso compound or lead salt, and for being bonded natural rubber or butadiene-styrene rubber and metal by heat cure mode, adhesive effect is good, and toxicity is low.
Description
Technical field
The present invention relates to a kind of vulcanization of rubber adhesives, more particularly to a kind of natural rubber/styrene-butadiene rubber metal fever sulphur
Change adhesive.
Background technology
Damping has a wide application in the car, such as subframe bushing, hydraulic bushing, crankshaft tortional vibration damper, dynamic
Power bump leveller dynamic vibration absorber.The material of these elements is largely metal, by metal surface adhesive rubber, can undoubtedly reach
To good damping effect.
There are many rubber-metal adhesives on the market now.For example CN93114420.5 discloses a kind of one-coat rubber
Glue-metal-to-metal adhesive.The adhesive contain halogen polyolefin, aromatic series nitroso compound, polymaleimide compounds and
Metal oxide.CN200710188735.1 discloses a kind of for elastomeric adhesive for another example.The adhesive includes extremely
A kind of few crosslinking agent：More nitroso compounds, more nitroso precursors and their mixture.Although these adhesives are bonded
It works well, but wherein has larger harm to environment containing nitroso compound or lead salt, and the component in this adhesive
Without containing above two substance.This adhesive is that unvulcanized natural rubber/styrene-butadiene rubber-gold is bonded by way of heat cure
Belong to.
Invention content
The purpose of the present invention is to provide a kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, of the invention is viscous
Mixture is free of nitroso compound or lead salt, for being bonded natural rubber or butadiene-styrene rubber and metal by heat cure mode, glue
It is good to connect effect, toxicity is low.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, described adhesive by following weight percent group
Divide and is made：Halogenated rubber 1-2%；Isocyanates 18-22%；Epoxy resin 9-12%；Balance of solvent.
A kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, the adhesive is by following weight percent
Component is made：Halogenated rubber 0.5-2.5%；Isocyanates 15-25%；Epoxy resin 7-15%；Balance of solvent.
A kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, the halogenated rubber be selected from neoprene,
It is one or more in chlorinated natural rubber, chlorinated scoline, brombutyl.
A kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, it is more that the isocyanates is selected from more phenyl
Methylene polyisocyanates, toluene di-isocyanate(TDI), methyl diphenylene diisocyanate, naphthalene diisocyanate, to two isocyanide of benzene
It is one or more in acid esters.
A kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, the epoxy resin are selected from bisphenol-A type ring
Oxygen resin（E-12）, bisphenol A type epoxy resin（E-20）, bisphenol A type epoxy resin（E-44）, bisphenol A type epoxy resin（E-
51）In it is one or more.
A kind of natural rubber/styrene-butadiene rubber metal fever vulcanizing adhesive, the solvent butanone, dimethylbenzene, acetic acid
It is one or more in ethyl ester.
Advantages of the present invention is with effect：
The adhesive of the present invention is maximum to be characterized in that being free of nitroso compound or lead salt, and toxicity is low, and adhesive effect is good.
For being bonded natural rubber or butadiene-styrene rubber and metal by heat cure mode, adhesive effect is good, and toxicity is low.
Specific implementation mode
The following describes the present invention in detail with reference to examples.
Above explanation and the following examples is for disclosure and illustrates the present invention, wherein each ingredient
Specific dosage and combination be not limited to by the scope of the present invention of claims defined.
In order to make sample, it with tetrachloro-ethylene steam by the steel disc degreasing Jing Guo blasting treatment, and dries.Steel disc is according to GB/T7760-
It is prepared by 2003 requirement, thickness be 1.5mm ± 0.1mm, such as using plastic plate or other planks when suitably thicken, the width of steel disc
Degree is 25mm ± 0.1mm, and length is 60mm ± 1mm.Before applying adhesive, first drawn at the 12.5mm of steel disc one end
Then straight line applies the adhesive of 0.03-0.04g on the coated face of each steel disc.
The steel disc for coating adhesive is placed under room temperature or certain temperature dry.
Unvulcanized natural rubber/styrene-butadiene rubber is cut into 25 × 12.5mm, then overlaps steel plate two-by-two, is put into flat
Vulcanization, temperature are heated in plate vulcanizer：150 DEG C, the time：20-30 minutes, the rubber to be bonded was as follows：
After curing, sample is tested after room temperature 24 hours.
Failure mode is R types, i.e. failure mechanics are in rubber face.
With reference to GB/T13936-92, test sample tensile shear strength.Use instrument：Microcomputer controlled electronic universal test
Machine, model RG1-30A, measuring speed 50mm/min.
The above formula result is as follows
It can be seen that from the above formula and data：Nitroso compound or lead salt are not contained in this adhesive, toxicity is low, adhesive property
It is good.
