Abstract
The invention relates to a rubber composition, belonging to the technical field of chemical industry, particularly the technical field of production of a rubber composition. The invention aims to provide a tough and wearable rubber composition. The technical scheme is as follows: the rubber composition comprises the following components in parts by weight: 50-60 parts of natural rubber, 20-80 parts of dry-process silicon dioxide with the specific area of not lower than 100 m<2>/g, 40-99 parts of resin component, 1-60 parts of granular talcum and 0-35 parts of rubber polymer. The granular talcum with the volume density of 0.4-1.5 g/ml is prepared by granulating talcum with the average grain size of 0.1-10 mu m; and the oversize of the granular talcum after passing through a 500-mu m screen accounts for 55 wt% above.
Description
Technical field
A kind of rubber combination of the present invention belongs to chemical technology field, especially relates to a kind of formula technique field of rubber bearing.
Background technology
Modern railways operational mode is for basic model with high speed, high-density, this pattern needs railway to provide satisfactory stability and rational route elasticity, and successively, the basis of railway is developed to rigidization, sweetly expensively think that neutralisation develops, this trend requires that circuit provides better elasticity.And rubber bearing just in time meets such requirement.In order to the demand of high-speed railway to rubber bearing can better be met, to adapt to the development of the high ferro of railway.Rubber is the basic raw material of rubber industry, is widely used in and manufactures tire, sebific duct, adhesive tape, cable and other various rubber items.Rubber is divided into natural rubber and synthetic rubber by raw material.Block rubber, latex, fluid rubber and powdered rubber is divided into by form.Latex is the colloidal water dispersion of rubber; Fluid rubber is the oligopolymer of rubber, is generally the liquid of thickness before unvulcanized; Powdered rubber be latex is processed into Powdered, in order to batching and processing and fabricating.The thermoplastic elastomer of the exploitation sixties in 20th century, without the need to chemicure, and adopts the working method of thermoplastics to be shaped.Rubber is divided into again universal and Special type two class by use.Be isolator, be not easy conduction, if but get wet or different temperature, likely become conductor.Conduction is the easy situation of conduction of the electronics about material interior molecules or ion.
Summary of the invention
In order to realize the rubber bearing of the present invention for the needs of high-speed railway, the invention provides following technical scheme: a kind of rubber combination, it comprises natural rubber 50 ~ 60 weight part, and 20-80 weight part has the dry silica of the specific surface area being not less than 100m2/g; Containing resin Composition 40 ~ 99 weight part, particulate state talcum 1 ~ 60 weight part and rubbery polymer 0 ~ 35 weight part, described particulate state talcum is that the talcum of median size 0.1 ~ 10 μm to be a granulated into volume density be the particulate state talcum that 0.4 ~ 1.5g/ml obtains, the granularity of described particulate state talcum is, the ratio of the screen overflow that mesh is 500 μm is more than 55 % by weight.
In order to better realize object of the present invention, above-mentioned technical scheme can further be improved:
Be that described natural rubber is 58 parts further, resin Composition is 65 parts.
Be that this kind of rubber is for making tire further.
Embodiment
In order to better explain technical scheme of the present invention, following concrete embodiment is adopted to introduce: a kind of rubber combination, it comprises natural rubber 50 ~ 60 weight part, and 20-80 weight part has the dry silica of the specific surface area being not less than 100m2/g; Containing resin Composition 40 ~ 99 weight part, particulate state talcum 1 ~ 60 weight part and rubbery polymer 0 ~ 35 weight part, described particulate state talcum is that the talcum of median size 0.1 ~ 10 μm to be a granulated into volume density be the particulate state talcum that 0.4 ~ 1.5g/ml obtains, the granularity of described particulate state talcum is, the ratio of the screen overflow that mesh is 500 μm is more than 55 % by weight.
In order to better realize object of the present invention, above-mentioned technical scheme can further be improved:
Be that described natural rubber is 58 parts further, resin Composition is 65 parts.
Rubber combination of the present invention may be used for making tire.
