Abstract
The invention relates to an acrylate rubber (ACM) and ethylene acrylate rubber (AEM) combined composition. The composition comprises the components as follows: acrylate rubber, ethylene acrylate rubber, fast-extrusion carbon black, a plasticizer, stearic acid, an interior release agent 18D, an antiager, a vulcanizer DIAK No.1 and diphenylguanidine as an accelerator. In the invention, by combining AEM and ACM, the rubber composition has the advantages that all the tensile strength, the elongation at rupture, the thermal and ageing resistance, the compression set property and the low-temperature resistance can be improved, and the oil resistance of the rubber composition is superior to that achieved by singly using the AEM, therefore, the composition provided by the invention is applied to the manufacture of rubber products with excellent high-temperature resistance, low-temperature resistance and oil resistance.
Description
Technical field
The present invention relates to the composition of a kind of acrylic elastomer and ethylene-acrylate rubber and usefulness.
Background technology
Acrylic elastomer (ACM) is a kind of heat-resisting, weather-proof, anti-ozone, the good specialty elastomer of oil resistance, be mainly used in automotive industry, the title of " automobile-used rubber " is arranged, be widely used in the manufacturing of engine and bent axle and products such as wheel box oil sealing, fuel hose thereof.
In this type of product material, require that acrylic elastomer is used for the prepared product of rubber layer and should have good high and low temperature resistance.But the temperature resistant range of acrylic elastomer (ACM) is narrow than ethylene-acrylate rubber (AEM), low temperature resistant, resistance to elevated temperatures is all not as ethylene-acrylate rubber (AEM), and the oil resistance of ethylene-acrylate rubber (AEM) is slightly poor than acrylic elastomer (ACM).
Technology as this type of problem of solution, in the prior art, acrylic elastomer is used for the prepared product of rubber layer, through finding that although it has sufficient physicals such as oil-proofness, anti-ozone, anti-weather-aging property, but its high and low temperature resistance deficiency, and the tensile strength of ethylene-acrylate rubber (AEM), elongation rate of tensile failure, tear strength, high and low temperature resistance all will obviously be better than acrylic elastomer (ACM), both and with after available can have the rubber combination of excellent properties more by complementary.
Summary of the invention
In view of above-mentioned situation, purpose of the present invention promptly is to provide a kind of acrylic elastomer and ethylene-acrylate rubber and use composition, and it can be used for making to high-low temperature resistant, oil resistance excellence and has the product of abundant physical property (as anti-ozone, anti-weather-aging property).
In order to address the above problem, deep research and discovery have been carried out, to high-low temperature resistant, oil resistance excellent and have the rubber item of abundant physical property (as anti-ozone, anti-weather-aging property) can be by using acrylic elastomer with ethylene-acrylate rubber and with making, this acrylic elastomer and ethylene-acrylate rubber also use the component and the mass fraction of composition as follows:
| Sequence number | Component | Mass fraction |
| 1 | Acrylic elastomer (ACM) | 20～80 |
| 2 | Ethylene-acrylate rubber (AEM) | 20～80 |
| 3 | The fast carbon black that extrudes | 65 |
| 4 | Softening agent | 2.5 |
| 5 | Stearic acid | 1 |
| 6 | Inner parting agent 18D | 1 |
| 7 | Anti-aging agent 445 | 2 |
| 8 | Vulcanizing agent DIAK 1# | 1.25 |
| 9 | The promotor vulkacit D | 1 |
The mass fraction of acrylic elastomer and two kinds of rubber of ethylene-acrylate rubber and be 100 parts in this prescription.
Acrylic elastomer and ethylene-acrylate rubber preferred, the acrylic elastomer trade mark is a lot, the acrylic elastomer that contains different cross-linking monomers, it is also inequality to add the man-hour vulcanization system, acrylic elastomer can be divided into five classes such as chloride polyamines cross-linking type, not chloride polyamines cross-linking type, self-cross linking type, ammonium carboxylate salt cross-linking type, soap cross-linking type now, generally select diamine and guanidine class vulcanization system because of the linking agent of AEM, this vulcanization system vulcanization rate is fast, cross-linking efficiency is high.Be the consistency that obtains, good inter-vulcanizability, so select to have the chloride polyamines cross-linking type of special crosslinking structure ACM; AEM selects the good Vamac IP of over-all properties glue according to its purposes.
Embodiment
Be described as follows table according to acrylic elastomer of the present invention and ethylene-acrylate rubber and with composite formula below, the proportioning of the component of prescription is a mass fraction.
In the foregoing description and the Comparative Examples, the oil resistance of visible pure ACM rubber is better than pure AEM rubber, but poor than AEM of tensile strength, elongation rate of tensile failure, tear strength, heat aging property, compression set, resistance to low temperature and pulse performance.
Can find out by the foregoing description and Comparative Examples, adopt AEM/ACM and usefulness, the tensile strength of rubber combination, tensile yield, heat aging property, compression set performance, resistance to low temperature improve, the oil resistance of rubber combination also than independent use AEM excellence, has rubber item high temperature resistant, low temperature resistant and that oil resistance is excellent so composition of the present invention is applied to make.
Claims (1)
1. acrylic elastomer and ethylene-acrylate rubber are also used composition, it is characterized in that component and mass fraction are as follows:
The mass fraction of acrylic elastomer and two kinds of rubber of ethylene-acrylate rubber and be 100 parts wherein.
