Technical field
The present invention relates to the rubber coating technical field, is a kind of non-pressure cure paracril coating and preparation method thereof specifically, can be used for the preparation of the material such as damping, sealing, sound insulation in the fields such as motor vehicle, refrigeration, oil, chemical industry, compressor.
Background technology
Paracril has good oil-proofness, wear resistance, thermotolerance and adhesiveproperties, is widely used in making oil-resistant article, also for making offset plate and wear part.But be all that the pressure vulcanized article is arranged mostly, during non-pressure cure at the bottom of poor, the vulcanizing agent utilization ratio of rubber coating degree of compactness, cause that rubber surface hardness is low easily to be scratched, the solvent resistance variation, easily self-adhesion, can't meet the service requirements of high-end product; After particularly making the continuous coiled material product, because destroying coating, can't use the rubber coating self-adhesion.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of non-pressure cure paracril coating is provided.
Another object of the present invention is to provide a kind of preparation method of non-pressure cure paracril coating.
When the present invention mainly solves existing non-pressure cure at the bottom of poor, the vulcanizing agent utilization ratio of rubber coating degree of compactness, solvent resistance variation, easy self-adhesion and can't meet the problem such as continuous coiled material product use.
Technical scheme of the present invention is: a kind of non-pressure cure paracril coating, and its special character is, by the raw material of following weight proportioning, is made: 100 parts of paracrils, carbon black 30-60 part, vulcanizing agent and auxiliary agent 1-10 part, resol 30-100 part, organic solvent 500-1100 part.
Further, described paracril is selected from the paracril of acrylonitrile content 30%-40%, a kind of or two kinds of mixing in carboxy nitrile rubber.
Further, described vulcanizing agent is sulphur or sulphur and the mixing of DCP.
Further, described resol is selected from a kind of or two kinds of mixing in alkyl phenolic resin, modified phenolic resins.
Further, the alkyl of described alkyl phenolic resin is butyl, octyl group, nonyl or phenyl.
Further, described organic solvent is methyl iso-butyl ketone (MIBK), butyl ester, three kinds of mixing of ethyl ester.
The preparation method of a kind of non-pressure cure paracril coating of the present invention, its special character is to comprise following processing step: paracril is put into to the open type rubber mixing machine and plasticate 4 times, then add carbon black, vulcanizing agent and auxiliary agent, on Banbury mixer mixing 6 times, section, then it is joined in organic solvent, add resol simultaneously, stirred, disperse, to be mixed evenly after, then drop into the sand mill sand milling 2 times, after sand milling, through filtration system filters, make paracril coating.
Non-pressure cure paracril coating of the present invention, be coated on the one or both sides of substrate surface, then carry out surface drying, sulfuration by any one or a few mode in blade coating, roller coat, dip-coating, showering, spraying, can be made into the metal-rubber composition board.
The metal-rubber composition board of being made by non-pressure cure paracril coating of the present invention, will be for automobile and motorcycle engine cylinder pad, vehicle-mounted air conditioner compressor pad, gearbox sealing gasket and other attachment pad the seals owner; Be mainly used in noise reduction, the bloop of brake system in the friction catch industry, can effectively reduce noise magnitude; Be mainly used in the sealing of the coarse flange face of pipeline in chemical industry; The field noise-reduction materials such as other electron trade computer, refrigerator.
Compared with the prior art a kind of non-pressure cure paracril coating of the present invention and preparation method thereof have outstanding substantive distinguishing features and marked improvement, 1, rubber coating has without pressurization only needs certain temperature to vulcanize, and there is good surface hardness, adhere to, self is antiseized; 2, the metal-rubber composition board made by it is significantly improved in performances such as damping noise reduction, stopping property, high temperature resistant, oil resistant, withstand voltage, corrosion-resistant, anti-non-freezing solutions than the composition board of coating system in the past, special self antiseized being significantly increased, meet or exceed the performance of pressing sulfuration substantially.
