Description
Technical field
The present invention relates to a kind of rubber compounding, this rubber has lower hardness, and has stronger bounding force between this rubber and the skeleton to guarantee stable bonding effect.
Background technology
In order to satisfy the performance requriements of component; The engine support of for example processing by skeleton and rubber adhesion, the durometer level that requires natural rubber unvulcanizate is 40 ± 3, tensile strength requires greater than 17Mpa; The hardness ratio of this rubber is lower; Tensile strength is than higher, and makes to have stronger bounding force between this rubber and the skeleton guaranteeing stable bonding effect, thereby guarantees the stability of quality product in process of production.
Summary of the invention
Problem to prior art exists the objective of the invention is to propose a kind of rubber compounding, and this rubber has lower hardness, and has stronger bounding force between this rubber and the skeleton to guarantee stable bonding effect.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of rubber compounding, each component and content are following:
NR, 100 parts;
Carbon black N550,20 parts;
Coumarone indene resin, 4 parts;

Preferably, WHITE CARBON BLACK, 8 parts.
Preferably, NO, 15 parts.
Preferably, WHITE CARBON BLACK, 8 parts; NO, 15 parts.
Preferably, said promotor is accelerant CZ.
Preferably, said anti-aging agent is an antioxidant 4010NA.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The present invention proposes a kind of rubber compounding, and this rubber has lower hardness, and has stronger bounding force between this rubber and the skeleton to guarantee stable bonding effect.
Embodiment
The objective of the invention is to propose a kind of rubber compounding, this rubber has lower hardness, and has stronger bounding force between this rubber and the skeleton to guarantee stable bonding effect.
On the one hand, the hardness of rubber is to adjust through the consumption of carbon black and tenderizer.In experimentation, carbon black adopts WHITE CARBON BLACK, and tenderizer adopts alkane oil, through the umber of adjustment WHITE CARBON BLACK and NO, confirms the influence of corresponding composition to rubber and skeleton bounding force, to confirm the prescription of rubber.
The WHITE CARBON BLACK particle surface be reactive behavior very strong be the acid face of characteristic with the silanol structure; Water adsorption is in WHITE CARBON BLACK ionic active face; Moisture is got off with the form fix of liquid water; Water is fettered and is uniformly distributed in the whole sizing material, reduced water enrichment on the interface between rubber and the tackiness agent, stoped the destruction of water glued construction.Alkane oil is filled into ejection easily in the rubber, and in rubber one tackiness agent interface enrichment, hinders rubber and the enrichment of tackiness agent interface, has hindered the abundant reaction of rubber and tackiness agent; Satisfying under the situation of request for utilization, should control the mark of alkane oil.
On the other hand,,, sizing material is fully combined with the tackiness agent top layer, can in rubber, add coumarone indene resin because coumarone indene resin can increase the viscosity of sizing material for the control of bounding force between rubber and the skeleton; Sulfur like NR, SBR etc., adopts general sulfur sulfide system and more helps bonding than adopting half effective sulfur sulfide system, effective sulfur sulfide system for polar rubber.All according to rubber and framework formula principle of design, add coumarone indene resin in prescription, vulcanization system adopts common vulcanization system, helps the bonding of rubber and skeleton more.
