Description
Technical field
The present invention relates to a kind of wax spray rubber, more particularly to a kind of wax spray BR/SBR material containing natural rubber powder.
Background technique
It is widely used to the row such as automobile, engineering machinery at present as a kind of emerging rubber material from wax spray rubber material
Bushing in industry, such as automobile industry can play the work of lubrication to avoid axis directly with bore opposite grinding using from wax spray bushing
With, the injury to axis is reduced, is lost when axis being enabled to do reciprocal and rotary motion in bushing and heat greatly reduces, also sustainable hair
Motivation and speed changer, and the vehicle body vibration generated by engine is buffered, so meeting is more stable in vehicle of driving a vehicle, more pacifies
Entirely.
Protection wax from wax spray rubber is with paraffin, microwax etc. for raw material, auxiliary material add the blending of a variety of auxiliary agent physics and
At the physical antioxidant with certain carbon number distribution and positive isoparaffin content.Under conditions of use, Wax-for preventing rubber is to pass through
Migration causes bloom, protective film is formed in rubber surface layer, to prevent rubber product from being encroached on by ozone and generating cracking.In order to
Better wax spray lubricant effect is obtained, is usually dosing lubricant from wax spray rubber, lubricant can be with according to its mode of action
It is divided into in-lubricant and external lubricant two major classes.In-lubricant is used to reduce the cohesive force of polymer molecule interchain, plays acceleration
Melting reduces melt viscosity, extends the effects of processing the service life, improving mobility and improve the transparency.External lubricant rises and prevents from melting
Melt attachment of polymers in the effect on heat-processing equipment surface, plays reduction friction, improves appearance glossiness and improve demolding performace.
In general, the structure composition of the inside and outside lubricant for same rubber is generally different, function is also different；For different rubbers
The lubricant of glue is more because of the molecular structure composition and polarity difference of rubber itself, it is desirable that composition, structure and the polarity of lubricant
It is matching to can be only achieved optimal lubrication and dispersion effect.The rubber material lubrication with lubricant effect of prior art production
Performance is bad and production cost is higher.
Summary of the invention
The purpose of the present invention is to provide a kind of wax spray BR/SBR material containing natural rubber powder uses in the present invention
