Abstract
A sealing fibre-rubber material contains synthetic mixed rubber and fibrous strengthening agent. Among them one or more of natural rubber, nitrile rubber, styrene butadiene rubber, sepiolite, aluminium silicate, glass fibre, carbon fibre and arylsulfone fibre are included. Its advantages are stable quality and high mechanical strength and resilience. It can be used for sealing at temp lower than 350 deg.C and pressure lower than 5-8 MPa.
Description
The present invention relates to a kind of sealing material, particularly relate to a kind of fiber rubber material, be used for joint or lid etc. and prevent to leak.
At present, sealing material generally all uses rubber as tackiness agent in the prior art, and as reinforcing agent, this sealing material has oil resistant, anti-solvent, high temperature resistant, corrosion resistance preferably with asbestos, and its mechanical strength is also higher.But asbestos fiber will cause lung cancer or other breathing problems as sucked respiratory tract and lung by the people after, and therefore, some countries are implementing progressively to forbid the measure making, sell, use.In addition, making asbestos rubber sealing material or some non-asbestos rubber sealing material generally all needs with a large amount of benzene and gasoline will to produce a large amount of harmful gas harmful to human so in process of production as solvent.
The objective of the invention is to overcome above-mentioned defective of the prior art, a kind of (non-asbestos) fibre rubber sealing material is provided, make it not need benzene and gasoline to make solvent in process of production, and further improve some performance index of sealing material.
The present invention is achieved through the following technical solutions its purpose.
The present invention includes following component and content (weight percentage): synthetic mixed rubber 26～35 fiber enhancers 35～70 sacrificial metals 0～25 aquadag 0～3 bulking agent 0.5～8
Wherein said synthetic mixed rubber contains following one or more components: natural rubber, nitrile rubber, styrene butadiene rubber; Described fiber enhancer contains following one or more components: sepiolite, alumina silicate, glass fibre, carbon fiber, polysulphonamide fiber; Described sacrificial metal is one or more in zinc powder, aluminium powder, the natrium nitrosum.
Owing to characteristics such as the present invention are made by materials such as (non-asbestos) lamination coating, rubber and other packing materials, and it is simple for process, and quality is more stable, has the mechanical strength height, and the compression rebound rate is good, the irreplaceable advantage of asbestos fiber rubber is arranged.Be applicable to industries such as boats and ships, automobile, chemical industry, generating, the piping flange valve port jointing that is used for equipment such as delivery industry water, superheated vapor, saturated vapour, seawater, air, flue gas, inert gas and petroleum gas is made the usefulness of liner.Applicable temperature is below 350 ℃ and pressure is the following occasion of 5MPa～8MPa.The concrete technical performance index of the present invention is: transverse tensile strength 〉=7MPa, oil absorbency≤23%, water absorption rate≤2%, thicken rate≤2%, density 1.6～2g/cm
3, compressibility is 12 ± 5%, rebound degree 〉=45%, aging coefficient are 0.8.
The present invention is further illustrated by the following examples.
