Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The features and properties of the present invention are described in further detail below with reference to examples.
The embodiment of the invention provides a high-strength rubber-based damping material which comprises the following raw materials in parts by weight: 100 parts of rubber and 50 parts of filler; wherein the rubber comprises 30-70 parts of natural rubber, 5-30 parts of cyclized rubber, 10-30 parts of epoxidized natural rubber and 15-40 parts of nitrile rubber according to parts by weight. The filler comprises 10-30 parts of carbon black, 5-20 parts of white carbon black, 5-15 parts of boron nitride and 10-30 parts of brick red soil in parts by weight.
The high-strength rubber-based damping material takes natural rubber as a main base material, fully utilizes the higher mechanical property and the processing property of the natural rubber, is simultaneously blended with various modified rubbers and synthetic rubbers, utilizes the higher glass transition temperature of the nitrile rubber and the cyclized rubber and the excellent compatibility of the epoxidized natural rubber, and can form a complex network structure by filling the filler, so that the high-strength rubber damping material taking the natural rubber as the main base material not only has a wider damping temperature range, but also has higher mechanical property, reduces the internal heat generation of the damping material, and has the advantages of high tensile strength, low heat generation and aging resistance.
In the examples of the present invention, the cyclized rubber has a cyclization degree of 50% to 90%; the epoxidation degree of the epoxidized natural rubber is 25 to 50 mol%; the acrylonitrile-butadiene rubber contains acrylonitrile more than 25%. The cyclized rubber and the acrylonitrile-butadiene rubber have higher glass transition temperature by controlling the cyclization degree of the cyclized rubber and the acrylonitrile content of the acrylonitrile-butadiene rubber, so that the high-strength rubber-based damping material prepared from the cyclized rubber has the properties of high tensile strength, low heat generation and aging resistance. Meanwhile, the epoxidized natural rubber has excellent compatibility by controlling the epoxidation degree of the epoxidized natural rubber, and can be further ensured to be used for preparing the damping material with high tensile strength, low heat generation and aging resistance. Of course, in other embodiments, the cyclization degree of the cyclized rubber, the epoxidation degree of the epoxidized natural rubber, and the acrylonitrile content in the nitrile rubber may also be adjusted according to requirements, and the embodiments of the present invention are not limited thereto.
It should be noted that, in the embodiments of the present invention, the carbon black is carbon black that performs a reinforcing function in rubber, and preferably reinforcing type carbon black, and may perform excellent reinforcing performance, so that the prepared damping material has excellent chemical and physical properties. Meanwhile, the white carbon black is precipitated white carbon black or gas-phase white carbon black. The white carbon black is largely classified into precipitated white carbon black and fumed white carbon black according to the production method. The fumed silica is white amorphous flocculent semitransparent solid colloidal nano particles (the particle diameter is less than 100 nm) in a normal state, is nontoxic and has a large specific surface area (100-400 m) 2 In terms of/g) (measured using the BET method using a F-Sorb 2400 specific surface area meter). The white carbon black prepared by the vapor phase method is completely nano silicon dioxide, the purity of the product can reach 99 percent, and the particle size can reach 10-20 nm. The precipitated silica is classified into conventional precipitated silica and special precipitated silica. The former refers to the use of sulfuric acid, hydrochloric acid, CO 2 The white carbon black produced by using the sodium silicate as a basic raw material is produced by adopting a special method such as a supergravity technology, a sol-gel method, a chemical crystal method, a secondary crystallization method or a reversed-phase micelle microemulsion method. The precipitated white carbon black is mainly used as a reinforcing agent of natural rubber and synthetic rubber, so that the strength of the damping material is effectively enhanced, the anti-aging characteristic of the damping material is ensured, and the service life of the damping material is prolonged.
In addition, it should be noted that boron nitride has chemical corrosion resistance, is not corroded by inorganic acid and water, can effectively ensure the anti-aging characteristic of the damping material, and meanwhile, has the advantages of low friction coefficient, good high-temperature stability, good thermal shock resistance, high strength, high thermal conductivity coefficient, low expansion coefficient, high resistivity, corrosion resistance, microwave or infrared ray permeability and the like, and can endow the damping material with excellent chemical and physical properties. Meanwhile, the brick red soil can be blended with other fillers with multiple functions to form a complex network structure with the damping substrate material, so that the brick red soil has a wider damping temperature range, the mechanical property of the damping material is improved, and the internal heat of the damping material is reduced.
Preferably, a vulcanization compounding agent is added in the preparation process of the damping material. It mainly comprises 2-ethyl zinc hexanoate, sulfur, zinc oxide, N-oxydiphenylidene-2-benzothiazole xanthene amide, di (sulfo-peroxy-dicarboxyl) tetrabutyl diamine and N-phenyl-alpha-naphthylamine. And the specific components are shown in the following table 1:
