Sulphur equipment carries out 15~25 minutes under 240 DEG C~320 DEG C high-temperature pressures；Step 3: being plasticized desulphurization plant in 240 DEG C in spiral
It is carried out 45~65 minutes under~320 DEG C of high-temperature pressures.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of method that oligomer ester makes full tire rubber powder high-strength reclaimed rubber of the present invention,
Rubber product is done using the novel and multifunctional rubber chemicals of oligomer ester, especially the most prominent with reinforcement nitrile rubber product, strength
It is stretched surely up to 13.2MPa, tearing toughness up to 36.4kN/m up to 22.9MPa, 100%.
Undersaturated double bond is contained in oligomerisation ester large molecule and macromolecular end, is to live containing multiple reactive functionalities
Property point it is more, the curing system of it and radical initiator composition participates in the friendship of dienes raw rubber strand under conditions of vulcanization
Connection, in the reticular structure of vulcanizate, other than C-C keys, the also compound ehter bond and sat linkage of long chain, to make vulcanizate
With certain new performance characteristics.
Oligomer ester is a kind of multifunctional assistant having both increase-volume, plasticising, reinforcement and sulfurization, is changed to the technique of rubber
The raising of kind and intensity has good effect, non-toxic inexpensive environmental protection.
Oligomer ester is also a kind of good " interim " plasticizer simultaneously, when compounding rubber is processed from plasticization, and sulphur
Crosslinked action can be played again when change, therefore, has good compatibility with rubber, calendering process can be improved, improve the object of vulcanizate
Mechanical performance is managed, the product of full tire powder reclaimed rubber is very suitable for.Oligomer ester multifunctional assistant is added in reclaimed rubber manufacture, it is the most prominent
The characteristics of going out is exactly its osmotic effect excellent to rubber powder granule, and makes the performance height of reclaimed rubber, is largely depended on
In the permeance property of auxiliary agent, could then facilitate low cost makes high performance reclaimed rubber product.
Reclaimed rubber products are done using the novel and multifunctional rubber chemicals of oligomer ester, not only the performances such as intensity improve, Er Qieyou
In it to vulcanized rubber particles（Powder）Penetration is strong, swelling effect is good, desulfurization depth is reinforced, desulfurization temperature reduces, and is a kind of
The ideal supporting material of environmental protection energy-saving, that production efficiency is high.It develops full tire rubber powder and makes high-strength reclaimed rubber product one newly
Path, material cost can reduce about 4.6%, power consumption reduce by 2.3~3.1%, production efficiency improve about 3.8%.
