Abstract
The invention relates to an adhesive preparation method for improving the adhesion strength of ethylene-propylene-diene-terpolymer rubber, which relates to an adhesive preparation method. The method comprises the steps: laminating the ethylene-propylene-diene-terpolymer rubber in a mixer at the temperature of 40 to 60 DEG C until the rubber cover a roll; adding a half of the measured metal hydroxide into the rubber and thinning for three times to guarantee the uniform mixing; slowly dropwise adding (methyl) crylic acid liquid, slowly adding the rest metal hydroxide to prevent the rubber from being separated from the roll, simultaneously adding a quinone-type compound and an organic peroxide in the rubber compound, thinning and laminating, and then batching-out the rubber for eight times by utilizing eight cutters. The adhesive is high in adhesion strength, the materials of an adhered base body are wide in source, the adhesive can be used for bonding different metals, different rubbers and ceramic materials, the bonding process is simple, the pollution in preparation and application can be avoided, and the preparation method is an environment-friendly technology.
Description
Technical field
The present invention relates to a kind of adhesive preparation method, particularly relate to a kind of adhesive preparation method that improves terpolymer EP rubber cohesive strength.
Background technology
Terpolymer EP rubber (EPDM) is the rubber being formed by ethene, propylene and the 3rd a small amount of monomer copolymerization.The main chain of EPDM is made up of chemically stable stable hydrocarbon, just in side chain, contains unsaturated double-bond, nonpolarity substituting group in molecule, and intermolecular internal cohesive energy is low, and therefore ethylene-propylene diene copolymer autohension and mutual viscosity are poor, rubber cement adhesive bonding power is also very poor.
At present, people, by acrylic or methacrylic acid is carried out to modification, make corresponding metal-salt, then add in rubber, play the effect of metlbond promotor in sulfuration, this auxiliary agent can be realized directly bonding, using method is easy, but bond properties is not bery desirable.
Summary of the invention
The object of the present invention is to provide a kind of adhesive preparation method that improves terpolymer EP rubber cohesive strength, this tackiness agent is by the metal hydroxides generation acid-base reaction in (methyl) vinylformic acid and terpolymer EP rubber, form corresponding (methyl) acrylate monomers, then add again superoxide and quinonoid compound evenly to mix with it, have that bond strength is high, the material of bonded matrix is extensive, bonding for various metals and various rubber and stupalith.
The object of the invention is to be achieved through the following technical solutions:
Improve an adhesive preparation method for terpolymer EP rubber cohesive strength,, described method comprises following preparation process:
First terpolymer EP rubber is carried out to pressing the temperature of 40-60 DEG C at mixing roll, until realize rubber bag roller; Then add in rubber thin-pass 3 times by 1/2 of the metal hydroxides total amount of metering, with ensure mixing evenly; Then slowly splash into (methyl) liquid acrylic, for preventing rubber roll release on roller, remaining 1/2 metal hydroxides is added slowly simultaneously, after again quinonoid compound and organo-peroxide are added in rubber unvulcanizate simultaneously, thin-pass pressing, through making a call to eight eight lower sheets of cutter; In terpolymer EP rubber, the content of two keys is 4-10%; Quinonoid compound contains anthraquinone, and quinonoid compound comprises 2-ethyl-anthraquinone; Metal hydroxides comprises hydrated barta, calcium hydroxide, aluminium hydroxide; Organo-peroxide is benzoyl peroxide, two-(tert-butyl hydroperoxide sec.-propyl) benzene.
Described a kind of adhesive preparation method that improves terpolymer EP rubber cohesive strength,, the add-on of described anthraquinone is the 0.01%-10% of Ethylene Propylene Terpolymer weight.
Described a kind of adhesive preparation method that improves terpolymer EP rubber cohesive strength, the add-on of described metal hydroxides is the 0.01%-40% of Ethylene Propylene Terpolymer weight.
Described a kind of adhesive preparation method that improves terpolymer EP rubber cohesive strength,, the add-on of described organo-peroxide is the 0.01%-5% of Ethylene Propylene Terpolymer weight.
Described a kind of adhesive preparation method that improves terpolymer EP rubber cohesive strength,, described (methyl) acrylic acid add-on is the 1%-20% of Ethylene Propylene Terpolymer weight.
Advantage of the present invention and effect are:
Tackiness agent of the present invention has that bond strength is high, the material of bonded matrix is extensive, can be used for various metals and various rubber and stupalith bonding, adhesion technique is simple, prepare and use pollution-freely, be a kind of technology of very environmental protection.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
The present invention, first by the metal hydroxides generation acid-base reaction in (methyl) vinylformic acid and terpolymer EP rubber, forms corresponding (methyl) acrylate monomers, then adds superoxide and quinonoid compound evenly to mix with it again.Mixture generates poly-(methyl) vinylformic acid (salt), (methyl) vinylformic acid (salt) also by under the effect at superoxide and quinonoid compound with ethylene-propylene-diene monomer xanthan molecule on active centre react, make rubber molecule there is polarity, thereby realize and metal, nonmetal and organism surface forms firmly surface adsorption, realizes effectively bonding.
