Abstract
The invention discloses a low-compression permanent deformation ethylene acrylate rubber compound. The low-compression permanent deformation ethylene acrylate rubber compound comprises the following raw materials by weight: 100 parts of ethylene acrylate crude rubber, 1-3 parts of anti-aging agent, 80-100 parts of MT carbon black N990, 0.5-2 parts of stearic acid, 1.0 part of vinyl acetate, 1.5-2.5 parts of 1# vulcanizing agent, 1.0 part of internal release agent 18D and 3-4 parts of accelerant DOTG. The permanent deformation rate of the ethylene acrylate rubber compound compressed for 70h at a high temperature of 150 DEG C is less than or equal to 15%, thereby being more favorable for maintaining sealing property of a sealing ring when in use.
Description
Technical field
The present invention relates to a kind of ethylene acrylic fat rubber unvulcanizate, especially relate to a kind of low compression set ethylene acrylic fat rubber unvulcanizate.
Background technology
Mixing of rubber is for cooperating reinforced filling, increment filler and giving the sizing that the additive of various performances is mixed with by the organopolysiloxane that contains the vinyl linear superpolymer (being commonly called as rubber).Main raw material(s) adopts the vinyl rubber, adds silicon-dioxide, bridging agent, and constitution controller, multiple material such as coupling agent forms through hot Banbury is mixing.Existing ethylene acrylic fat rubber equal conditions lower compression permanent set is more than 20%, and deformation rate is bigger than normal when producing tighter sealing-ring, is unfavorable for that sealing property keeps.
Summary of the invention
The technical problem that the present invention will solve provides a kind of low compression set ethylene acrylic fat rubber unvulcanizate; This rubber unvulcanizate under 150 celsius temperatures through 70 hours compression set rates≤15%; Be more conducive to the maintenance of sealing property in the sealing-ring use.
For solving above-mentioned first technical problem, a kind of low compression set ethylene acrylic of the present invention fat rubber unvulcanizate, form by the raw material of following parts by weight:
100 parts of ethylene acrylic fat rubbers, 1～3 part in anti-aging agent,
80～100 parts of MT carbon black N990,0.5～2 part of Triple Pressed Stearic Acid,
1.0 parts of vinyl acetates,
Hexyl diamino carbamate (be called for short: the .5～2.5 part 1# vulcanizing agent),
1.0 parts of inner parting agent 18D,
1,3-two-neighbour-tolyl guanidine (is called for short: vulkacit D OTG) 3～4 parts.
Preferably, can also comprise 10 parts of softening agent TP759 in the said ethylene acrylic fat rubber unvulcanizate.
Rubber unvulcanizate of the present invention obtains through ordinary process is mixing with above-mentioned raw materials.
Preferably, said anti-aging agent is anti-aging agent 445, antioxidant BLE or antioxidant 4010NA.
Said 1# vulcanizing agent is the commercial goods, and for example: German CHEMMIS company produces.
Said inner parting agent 18D is the commercial goods, and for example: German CHEMMIS produces.
Said softening agent TP-759 is the commercial goods, as: gram difficult to understand excellent International Trading Company Ltd in Tianjin sells.
In the prescription of ethylene-acrylate rubber rubber unvulcanizate in the present invention,, can obtain the ethylene acrylic fat rubber unvulcanizate prescription of different hardness through ratio adjustment to MT carbon black N990; Through to the 1# vulcanizing agent, that vulkacit D OTG difference is relatively adjusted the ethylene acrylic fat that can obtain different cure conditions is rubber mixed.
Prescription of the present invention is with the mixing rubber unvulcanizate stable performance that obtains of ordinary process, and sulfidation technology is simple, scrap rate is few, and the goods glossiness is good; This rubber unvulcanizate 70 hours compression set rates of warp under 150 celsius temperatures are more conducive to the maintenance of sealing property in the sealing-ring use≤15%.
