Description
Technical field
The invention discloses a kind of preparation methods of blown rubber composite metal plate, belong to technical field of function materials.
Background technique
Composite metal plate is that the different metal of performance is realized metallurgical bonding and shape on interface using various complex techniques
At composite material.By suitable material selection and reasonable structure design, composite metal plate can significantly improve single
Many performances such as thermal expansivity, intensity, toughness, wear resistance, corrosion resistance, electrical property, the magnetic property of metal material, thus quilt
It is widely applied to the industrial circles such as petroleum, chemical industry, ship, metallurgy, electric power, water conservancy, traffic, environmental protection, food, pharmacy.Metal
Composite plate can also save the use of noble metal other than with structural and functional feature, significantly reduce various dresses
The cost of standby material.Metal-rubber composite material is to coat one layer of bullet in the two sides or one side of metal plate using metal plate as matrix
Property body rubber coating.The high resiliency of this existing rubber elastomer of composite material, excellent compressibility, but also with metal core board
High intensity, therefore have excellent sealing performance and antivibration, heat resistance, protection, sealing, anti-impact can be played in different occasions
Hit, vibration damping, it is heat-resisting the effects of, especially its structure and excellent leakproofness obtain it extensively in field of sealing technology such as motor vehicles
General application.Metal, which covers glue material earliest, to be applied in the cylinder gasket of automobile, and traditional cylinder gasket is copper sheet packet asbestos
Template, since the price of copper is higher, and poor performance, it is most of to have eliminated, then produce using steel disc as the asbestos of backing material
Butyronitrile rubber cylinder head gasket.But the use temperature of pure nitrile rubber is very low, has been unable to satisfy the requirement of modern automobile industry.It is multiple
Plywood main raw material(s) is rubber and metal core board, applies very extensive at positions such as automobile, suitcase, engine components.
Wherein automobile sealing plate mainly has rubber product, plastic products, rubber-plastic composite product and four kinds of thermoplastic elastomer article.It is early
The sealing plate primary raw material of phase is natural rubber and neoprene.But this rubber is no longer satisfied modern industrial production
The performance requirements such as weatherability and service life are long.
And the adhesive force of traditional blown rubber composite metal plate rubber surface coating the problem of can not further increasing.Cause
This, the shortcomings that how improving traditional blown rubber composite metal plate is that it is promoted and answers to obtain the promotion of more high combination property
For broader field, meet industrial production demand urgent problem to be solved.
Summary of the invention
The present invention solves the technical problem of: for the attached of traditional blown rubber composite metal plate rubber surface coating
Put forth effort the problem of can not further increasing, provides a kind of preparation method of blown rubber composite metal plate.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of preparation method of blown rubber composite metal plate, specific preparation process is as follows:
(1) according to parts by weight, 40~50 parts of base rubbers are successively taken, 200~400 parts of solvents, 8~10 parts of zinc oxide, 5~8
