Abstract
The invention relates to a combined composite of chlorosulfonated polyethylene rubber and epichlorohydrin rubber for an outer rubber layer of a crankcase ventilation duct. The combined composite comprises the following rubber components in part by mass: 50 to 80 parts of chlorosulfonated polyethylene rubber, 20 to 50 parts of epichlorohydrin rubber, 2.2 parts of fast extruding furnace carbon black, 80 parts of precipitated calcium carbonate, 10 parts of dioctyl, 10 parts of magnesium oxide, 1 part of stearic acid, 6 to 9.6 parts of epoxy resin, 1 part of anti-aging agent NBC, 2 parts of flow aid WB222, 0.5 to 0.8 part of promoter DM, 0.75 to 1.2 parts of dipentamethylenethiuram tetrasulfide (DPTT) serving as a promoter, 0.75 to 1.2 parts of promoter HVA-22 and 0.2 to 0.5 part of promoter NA-22. According to the combined composite, the outer rubber layer of the crankcase ventilation duct, which is resistant to low temperature, high temperature and ozone and high in physical and mechanical properties is manufactured by adjusting the combined ratio of the chlorosulfonated polyethylene rubber and the epichlorohydrin rubber.
Description
Technical field
The present invention relates to the rubber technology field, particularly a kind ofly be used for the chlorosulfonated polyethylene rubber and the epichlorohydrin rubber of the outer glue-line of crankcase bleed pipe and use compsn.
Background technology
Along with developing rapidly of automotive industry, there are bigger opportunities and challenges in automobile component manufacturer, each main engine plants to automobile with sebific duct select also harshness further of requirement for use, material performance requirement is also improved constantly.
The chlorosulfonated polyethylene rubber softness that to be Vilaterm make after chlorination and sulfonation are handled and whippy macromolecular material; It has excellent ozone-resistant aging property, firing resistance, anti-weather-aging property and good processing properties; But its resistance to low temperature is relatively poor, has limited its application in a lot of occasions.
The external glue-line of a lot of auto vendors is that the crankcase bleed pipe that chlorosulfonated polyethylene rubber makes requires it can bear-40 ℃ low temperature; Its low temperature resistant grade of simple chlorosulfonated polyethylene rubber is-30 ℃; Can not satisfy client Nai-40 ℃ of cryogenic requirement; Reach-46 ℃ and epichlorohydrin rubber is low temperature resistant, high temperature resistant similar with chlorosulfonated polyethylene rubber.Therefore for satisfying requirement of client, improve the share of market of product, a kind of chlorosulfonated polyethylene rubber and epichlorohydrin rubber and imperative that is used for the outer glue-line of crankcase bleed pipe of development and Design with compsn.
Summary of the invention
The object of the invention just provides a kind of chlorosulfonated polyethylene rubber of the outer glue-line of crankcase bleed pipe and epichlorohydrin rubber of being applicable to and also uses compsn; Through rational formulating of recipe, obtain a kind of have excellent physical and mechanical performance, excellent heat-proof aging, anti-ozone ageing and the excellent chlorosulfonated polyethylene rubber compsn of resistance to low temperature.
Chlorosulfonated polyethylene rubber of the present invention and epichlorohydrin rubber are also used compsn, and rubber component and mass fraction prescription are following:
| Chlorosulfonated polyethylene rubber | 50～80 parts, |
| Epichlorohydrin rubber | 20～50 parts, |
| The fast carbon black that extrudes | 2.2 part, |
| Fine particle calcium carbonate | 80 parts, |
| Dioctyl ester | 10 parts, |
| Natural manganese dioxide | 10 parts, |
| Triple Pressed Stearic Acid | 1 part, |
| Epoxy resin | 6～9.6 parts, |
| Antioxidant NBC | 1 part, |
| Flow promotor WB222 | 2 parts, |
| Altax | 0.5～0.8 part, |
| Vulkacit D PTT | 0.75～1.2 parts, |
| Vulkacit H VA-2 | 0.75～1.2 parts, |
| Accelerant N A-22 | 0.2～0.5 part. |
Chlorosulfonated polyethylene rubber and epichlorohydrin rubber preferred: the epichlorohydrin rubber that adopts copoly type; Though because homopolymerization type epichlorohydrin rubber has polyether backbone, the chloromethyl that contains because of its side chain makes its winter hardiness relatively poor, and the copoly type epichlorohydrin rubber is because chloromethyl is less; So its winter hardiness is better; And with the increase of oxyethane copolymerization ratio, winter hardiness can further improve, through also using of chlorosulfonated polyethylene rubber and epichlorohydrin rubber; Can obviously improve the resistance to low temperature of chlorosulfonated polyethylene rubber, thus obtain excellent combination property and use compsn.
Effect of the present invention; The outer glue-line color of the crankcase bleed pipe that this invention makes is a grey; Adopt this chlorosulfonated polyethylene rubber and epichlorohydrin rubber and both guaranteed with compsn that product has the anti-ozone ageing and the heat aging property of higher physical and mechanical properties, excellence, guaranteed that again product has the good low-temperature resistance performance.
Embodiment
The present invention obtains to have the outer glue-line compsn of crankcase bleed pipe of excellent properties through adjusting chlorosulfonated polyethylene rubber and epichlorohydrin rubber also with the proportioning of each component in the compsn, and embodiment is following:
Can find out by data sheet, chlorosulfonated polyethylene rubber and epichlorohydrin rubber and with after still have excellent physical and mechanical performance and heat-resisting, ozone-resistant aging property, and obviously improved the resistance to low temperature of chlorosulfonated polyethylene rubber.
Can find out by the foregoing description; Epichlorohydrin rubber along with blend different ratios in the chlorosulfonated polyethylene rubber; The resistance to low temperature of blended rubber obviously improves, so can be through crankcase bleed pipe adjustment chlorosulfonated polyethylene rubber and epichlorohydrin rubber and that have resistance to low temperature, resistance to elevated temperatures, ozone resistance and have an excellent physical mechanical property with ratio manufacturing glue-line outward.
