Abstract
The invention relates to a dynamic ozone resistant neoprene which comprises the following components: neoprene CR322-2, copoly-epichlorohydrin rubber containing a third monomer AGE, dioctyl phthalate DOP, fast extruding carbon black N550, half-reinforced carbon black N774, anti-aging agent A, anti-aging agent KY-405, anti-aging agent WSP, magnesia, stearic acid, dibenzothiazyl disulfide DM, 1,2-hexylidene thiocarbamide NA-22 and tetramethyl-thiuram disulfide. The neoprene of the invention resists dynamic ozone, and the utility time of a neoprene hose on an entire car is prolonged, so that the neoprene hose is safer. Through experiments, the rubber of the invention does not generate a crack phenomenon in a dynamic ozone environment of 50PPhm*40 DEG C*elongation of 30%*frequency of 1Hz for 100 hours.
Description
Technical field
The present invention relates to the sebific duct technical field, particularly the X 050 of anti-dynamic ozone.
Background technology
Automobile has been dissolved in the daily life of people as the mankind's the vehicles, as the function of the rubber hose that connects vehicle fuel system, cooling system, heat-removal system keep just showing particularly important.Along with the development of automobile industry, automobile is more and more abominable with the environment for use of sebific duct, connects flexible pipe as automobile with rubber; Can stretch, under the normal circumstances along with the uneven shake of road conditions; The anti-static ozone excellent property of X 050; But under the bad condition of road conditions, the automobile pipe connecting is in dynamically, and this just requires X 050 except anti-static ozone; Also want anti-dynamic ozone, in the ozone environment of 50PPhm * 40 ℃ * elongation 30% * frequency 1Hz, crack performance can not occur in 100 hours.And crack performance just appearred in 24 hours in simple X 050 under this condition, and it is imperative therefore to develop new product.
Summary of the invention
The object of the invention mainly is to improve the anti-dynamic ozone property of X 050, prolongs the X 050 flexible pipe on car load
Duration of service, make it safer.
The X 050 of anti-dynamic ozone of the present invention, its component and mass fraction are following:
| Sequence number | The starting material title | Massfraction |
| 1 | X 050 (CR322-2) | 30～50 |
| 2 | Contain the 3rd monomer (AGE) copolymerization epichlorohydrin rubber | 5～20 |
| 3 | DOP DOP | 4～8 |
| 4 | The fast carbon black N550 that extrudes | 10～30 |
| 5 | Semi-reinforcing hydrocarbon black N774 | 10～40 |
| 6 | Antioxidant A | 1～2 |
| 7 | Anti-aging agent KY-405 | 0.5～2 |
| 8 | Anti-aging agent WSP | 0.5～2 |
| 9 | Natural manganese dioxide | 1～4 |
| 10 | Triple Pressed Stearic Acid | 0.5～1.5 |
| 11 | Dibenzothiazole disulfide DM | 0.5～2 |
| 12 | 1,2-hexylidene thiocarbamide NA-22 | 0.5～1.5 |
| 13 | Tetramethyl-thiuram disulfide | 0.5～2 |
The present invention adopts X 050 and contains the 3rd monomer (AGE) copolymerization epichlorohydrin rubber and use structure, and interpolation anti-aging agent KY-405, WSP reach the effect of anti-dynamic ozone, has improved resistance toheat, wear resistance and the elasticity of rubber simultaneously.The present invention uses contains the 3rd monomer (AGE) copolymerization epichlorohydrin rubber (being the unsaturated type multipolymer by epoxy chloropropane, oxyethane, the 3rd monomer glycidyl allyl ether), owing to be greatly improved because of containing its anti-dynamic ozone of glycidyl allyl ether in this material.
Anti-aging agent KY-405,4,4 '-two (a, a-dimethyl benzyl) pentanoic because tree elastomer, X 050, butyl rubber etc. are because heat, light, ozone is caused wears out, has good synergistic effect with the oxidation inhibitor of sulfur-bearing.To the thermo-oxidative ageing of cross-linked rubber and repeatedly the destruction under the texturizing condition fine protective effect is arranged, be particularly useful for X 050.
Anti-aging agent WSP, 2,2 '-methylene radical [4-methyl-6-(a-methylcyclohexyl) phenol]; Being white crystalline powder, is the elastomeric oxidation inhibitor of tree elastomer, and thermo-oxidative ageing is had significant protective effect; The ability of metals ion to the rubber catalyzed oxidation that suppress arranged; Stress at definite elongation to cross-linked rubber has the reduction effect simultaneously, because elastomeric material is stretched the reduction of strength surely, sebific duct shake or telescopic process just can not form stress concentration; Thereby effectively improve the anti-dynamic ozone performance of rubber, prolong the duration of service of sebific duct.
With containing anti-aging agent KY-405 and the anti-aging agent WSP that the 3rd monomer (AGE) copolymerization epichlorohydrin rubber adds simultaneously, improved the anti-dynamic ozone performance of this rubber through also greatly.
Embodiment
The embodiment of anti-dynamic ozone rubber sees table
Content is in mass fraction:
The experimental performance detected result of above-mentioned instance is following:
Through experiment, crack performance did not appear in 100 hours in rubber of the present invention under 50PPhm * 40 ℃ * dynamic ozone environment of elongation 30% * frequency 1Hz.
The anti-dynamic ozone rubber that the present invention proposes; Describe in detail through above, person skilled obviously can be in not breaking away from content of the present invention, spirit and scope to rubber components as herein described and content is changed or suitably change realize the present invention's technology with combination.Special needs to be pointed out is, the replacement that all are similar and change apparent to those skilled in the artly, they are regarded as and are included in spirit of the present invention, scope and the content.
