Abstract
The invention relates to a rubber composite used for the power steering oil suction hose. The composite comprises the following components: chorosulfonated polyethylene CSM-40M, reinforcing agent N330, light calcium carbonate used as filler, plasticizer T810T, anti-aging agent NBC, magnesium oxide used as vulcanizing agent and vulcanizing agent HVA-2. The rubber composite of the invention uses magnesium oxide in a metal oxide curing system and N,N'-m-phenylene bismaleimide in an organic nitrogen compound curing system commonly, wherein light magnesium oxide is selected which is white unshaped power, is odorless, tasteless and non-toxic and has good effect of improving the mechanical properties of rubber; N,N'-m-phenylene bismaleimide is named as HVA-2 which can be used to significantly improve the crosslinking performance and increase the heat resistance; HVA-2 is used as auxiliary curing agent and can be used to significantly improve the connection performance and obviously reduce the compression set. The rubber composite used for the power steering oil suction hose can meet the requirements of the product in many aspects such as appearance, size and environmental protection and be more suitable for the actual production and applications of CSM rubber.
Description
Technical field
The present invention relates to the automobile rubber technical field of hoses, relate to the rubber combination that is applied to power steering oil suction flexible pipe.
Background technology
Flourish along with automobile industry, the automobile component consumption continues to increase.It in the power steering system steering characteristic that improves vehicle, make driving more light, automobile has extensively adopted steering boost system, also often is called as " power steering ", and automobile steering system can be divided into manual steering system power steering system two classes of unifying by the energy difference that turns to.The mechanical steering system relies on the steering force of pilot control steering wheel to realize wheel steering; Power steering system then is under officer's control, and the liquid pressure or the motor force that produce by means of motor car engine realize wheel steering.Power steering is divided into low-pressure hose, middle pressure flexible pipe and high pressure hose, and power steering low pressure rubber hose is called the oil suction flexible pipe again, adopts chlorosulphonation rubber to produce traditionally.
Chlorosulphonation rubber full name is chlorosulfonated polyethylene elastomer, be that Dupont came out in nineteen fifty-two, occur Hypalon-30, Hypalon-40, Hypalon-45 and many models of Hypalon-48 mutually, and the chlorosulfonated polyethylene device of E.I.Du Pont Company has stopped production in mid-April, 2010.Japan eastern Cao company also is one of main manufacturer of chlorosulfonated polyethylene rubber in the world, but can't satisfy international market demand.Present domestic chlorosulfonated polyethylene based on Jilin Petrochemical company of CNPC, model is CSM40L, CSM40M, CSM40H.Chlorosulfonated polyethylene has multiple cross-linking system: metal oxide, organic nitrogen compound, polyvalent alcohol, Resins, epoxy.
The cross-linking system of metal oxide is best with plumbous class effect, but for tackling the needs of current world market and environmental requirement, this type of vulcanization system is restricted; In the sulfur-crosslinked system of alcohols, alcohol is the high-melting-point crystal, is difficult for disperseing in sizing material, workload need have been strengthened in its sieving to obtain fine powder end when producing during use; The organic nitrogen compound system makes that the crosslinking degree of rubber is poor, and serious scorching phenomenon is arranged; The cross-linking system product size less stable of epoxy resin.
Summary of the invention
That the present invention selects for use is the chlorosulfonated polyethylene CSM-40M that Jilin Petrochemical company of domestic CNPC produces, to tackle the in short supply of current international raw material, the rubber combination of power steering oil suction flexible pipe of the present invention can satisfy the requirement of product in many-side, outward appearance, size and environmental protection are fit to the actual production and the application of chlorosulfonated polyethylene rubber more.
The component and the mass fraction of rubber combination of the present invention are as follows:
100 parts of chlorosulfonated polyethylene CSM-40M
40～60 parts of strengthening agent N330
10 parts of weighting agent light calcium carbonates
5～10 parts of softening agent T810T
2 parts of antioxidant NBCs
1～3 part in vulcanizing agent magnesium oxide
1～3 part of vulcanizing agent HVA-2
The present invention is an example with rubber 100 weight parts, magnesium oxide in the employing metal oxide vulcanization system and the N in the organic nitrogen compound vulcanization system, and a N '-penylene bismaleimides is also used.Magnesium oxide is selected light magnesium oxide for use, white, and unformed powder, odorless, tasteless, nontoxic, rubber physical mechanical property there is good effect.N, the English name HVA-2 of a N '-penylene bismaleimides can significantly improve cross-linking properties, improves thermotolerance, and HTV-2 can significantly improve related performance as auxiliary vulcanizing agent, and it is fairly obvious to reduce compression set.
Adopt rubber combination of the present invention to be used for power steering oil suction flexible pipe, its cure conditions: steam vulcanization, 150～190 ℃ of temperature, time 10～30min, pressure 0.6～1.2bar are adopted in sulfuration.
