Main raw material performance analysis is as follows:
Chlorosulfonated polyethylene is poly derivative, polyethylene is dissolved in tetracol phenixin, tetrafluoroethylene or hexachloroethane, take azo-bis-isobutyl cyanide as catalyzer or under uviolizing, by the gas mixture of chlorine and carbonic acid gas or undertaken reacting by thionyl chloride and obtain.It has ageing-resistant, ozone resistance, and oil resistance is only second to butyronitrile and chloroprene rubber, owing to also having good firing resistance containing chlorine element in its molecular chain.
Carbon black N330 is the high wearable carbon black be most widely used, iodine absorption value 82g/kg, DBP absorption value 102cm
3/ 100g, in its wear resisting property ratio, super abrasive series is slightly poor, but is better than carbon black prepared by channel process, and it has, and middle height is reinforcing, medium modulus and excellent processing performance.But adopt this kind of carbon black separately, although strengthening action and processing characteristics can have greatly improved, but power steering tube requires higher to compression set, this just needs to select the better carbon black of other compression sets come and use, N990 is MT medium thermal black, structure is quite low, can fill in a large number, but it is low to be used alone tensile strength, in order to improve the over-all properties of rubber unvulcanizate, by N330 and N990 and use, not only meet the tensile strength that rubber unvulcanizate is higher, and compression set better performances, compensate for the shortcoming be used alone.
Product is made to obtain higher tensile strength by adding mineral strengthening agent GC in the present invention, better tensile yield and rebound resilience, better resistance toheat, increase the very property of sizing material, reduce the contraction of sizing material, improve the flexible resistance of sizing material, improve the fillibility of product.
Environment-friendlyplasticizer plasticizer TOTM is a kind of heat-resisting and permanent seal cooling softening agent, and have the advantage of polyester plasticizer and monomeric plasticizer concurrently, plasticizing efficiency is close with phthalic ester plasticizer with processing characteristics; Consistency, plasticizing capacity, low-temperature performance are excellent compared with polyester plasticizer; Improve the environmental-protecting performance of sizing material.Adopt the tenderizer petroleum and itself use with synergistic effect, be more conducive to viscous deformation, reduce shearing modulus, obtain larger displacement.
In the present invention by adding anti-aging agent RD and antioxidant NBC and using, product can be made to have excellent resistance toheat, ozone resistance, heat-proof water steam performance, better resistance to weather, simultaneously to flex crack, thermo-oxidative ageing also has good protective effect, and wherein antioxidant NBC has satisfactory stability effect to light, oxygen, ozone and heat.
Add WB212 dispersion processing auxiliary agent and WS180 processing aid in the present invention, the dispersiveness of sizing material can be improved, shorten the mixing time of sizing material, improve processing performance, reduce the danger of early stage incipient scorch, also there is good plasticising performance simultaneously, improve the flowing property of sizing material and the demolding performace of finished product.
Adopt in the present invention and comprise the peroxide vulcanizing system of crosslinking coagent, the winter hardiness of rubber is improved and compression set minimum, also comparatively greatly, fatigability is fine for tensile strength and tensile yield simultaneously.This advantage is used alone superoxide, and use the combination of superoxide, sulphur and other additional crosslinkers as not available for vulcanization system.
Adopt formula of the present invention and preparation method's mixing of rubber, after measured, the performance of chlorosulfonated polyethylene rubber prepared by the present invention reaches following index:
Hardness (shore A) 65 ± 5; Tensile strength > 12Mpa; Tensile yield > 250%; Compression set < 20%(100 DEG C × 72h, compression 25%); Ozone resistance (50ppm × 40 DEG C × 24h stretches 20%) is good; Lower temperature resistance (-40 DEG C) is good; Ageing resistance (125 DEG C × 168h) is good.
Formula of the present invention has high strength, low compression set, low temperature resistant, ageing-resistant, resistance to wet goods characteristic, reaches the requirement of power steering tube completely, simultaneously nontoxic, tasteless, storage-stable.The power steering tube oil resistant, the antifatigue that prepare according to formula of the present invention, the vibrations can eliminating engine are delivered on storage tank, reduce loosening of each interface of storage tank, substantially prolongs the working life of automobile power steering system; Stability Analysis of Structures is firm simultaneously, not easily produces leak of liquid.This formula is also applied to the product similar to power steering tube performance.
