Abstract
A kind of wax spray NR/BR material containing natural rubber powder, is related to a kind of rubber material, has following group to be in parts by weight grouped as: 100 parts of rubber；1 part of organic active agent；4 parts of inorganic active agent；1 ~ 1.5 part of rosin；1.5 ~ 2.5 parts of dispersing agent；2.5 parts of anti-aging agent；6 parts of plasticizer；5 parts of lubricant；40 ~ 50 parts of reinforcing agent；1.5 parts of promotor；2 ~ 2.5 parts of vulcanizing agent.Present invention discover that raw material employed in a kind of preparation method of made wax spray NR/BR material containing natural rubber powder realizes waste utilization, environmental protection and saving production cost, the surface of product will form smooth cere, reduce coefficient of friction, increase wear-resisting property, the service life for extending product has practical significance to the industrial production of rubber product.
Description
Technical field
The present invention relates to a kind of rubber materials, more particularly to a kind of wax spray NR/BR material containing natural rubber powder.
Background technique
There are mainly three types of the processing modes of damaged tire: tyre rebuilding, reclaimed rubber and ground rubber, wherein waste tire adds
Tire glue powder made of work constantly progresses greatly with production technology, also more and more important in the status of rubber product industry, more low
It is largely filled in shelves rubber product.Waste tyre rubber powder acts not only as filler use in rubber product, is also used as leading
Body material is largely mixed.Tire glue powder be waste tire under the action of mechanical shear stress through made of crushing and processing, grinding, it is former
Expect source it is more, product price is low, it is possible to reduce rubber raw materials dosage, increase rubber product volume, reduce rubber product raw material at
This.Tire glue powder can not only reduce rubber product cost of material, can also change by exclusive molecular structure and performance characteristics
Kind rubber product performance, the compatibility of tire glue powder and various raw rubbers, reclaimed rubber is good, can send out in different rubber products
Wave different effects.
Tire glue powder is mixed in automobile tire tyre surface can reduce tire dynamic heat build up, improve rubber tyre wear-resisting property,
Prolong the service life；In rubber floor tile add tire glue powder can achieve sound-absorbing, noise reduction, damping effect；Tire glue powder is one
Kind powder rubber material, its particle size, configuration of surface etc. can all influence its service performance, and usual tire glue powder fineness is got over
Height, performance are better.When tire glue powder fineness is sufficiently high, mixing tire glue powder in rubber product hardly influences rubber system
Tensile strength, elongation at break and the wear-resisting property of product itself, even the raising wearability of rubber product, fatigue durability with
And tearing toughness, tire glue powder must be mixed as needed for performance in some rubber products.Tire glue powder fineness is higher simultaneously,
It is smaller for the influence of rubber article smooth degree, or improve rubber product brightness.
Summary of the invention
The purpose of the present invention is to provide a kind of wax spray NR/BR material containing natural rubber powder, natural rubber of the present invention
For the wax spray NR/BR material of powder while saving production cost, mechanical property is unaffected or even wearability is more preferable.
The purpose of the present invention is what is be achieved through the following technical solutions:
Base rubber used in the present invention is natural rubber (SCR5), butadiene rubber (BR9000) and 60 mesh natural rubber powder, institute
Vulcanizing system is sulfur cross-linking system, obtained rubber product properties can be up to state standards and intensity it is high,
Wear-resisting and self-lubrication is good.
The present invention provides a kind of wax spray NR/BR material containing natural rubber powder, which is characterized in that have following with weight
The group of part meter is grouped as:
100 parts of rubber；
1 part of organic active agent；
4 parts of inorganic active agent；
1 ~ 1.5 part of rosin；
1.5 ~ 2.5 parts of dispersing agent；
2.5 parts of anti-aging agent；
6 parts of plasticizer；
5 parts of lubricant；
40 ~ 50 parts of reinforcing agent；
1.5 parts of promotor；
2 ~ 2.5 parts of vulcanizing agent.
The rubber is preferably the combination of natural rubber (SCR5), butadiene rubber (BR9000) and 60 mesh natural rubber powder
Object；
The organic active agent is preferably stearic acid；
The inorganic active agent is preferably zinc oxide；
The dispersing agent is preferably dispersing agent KT-8A；
The anti-aging agent is that anti-aging agent is N- phenyl-1-naphthylamine (antioxidant A) and N- isopropyl-N'- diphenyl-para-phenylene diamine
The composition of (4010NA)；
The plasticizer is preferably coumarone and paraffin；
The lubricant is preferably the composition of amides slipping agent erucyl amide and oleamide；
The reinforcing agent is preferably carbon black N330 and N774；
The promotor be preferably sulfenamide type accelerators N cyclohexyl 2 benzothiazole sulfenamide (accelerant CZ) and
The composition of thuriam acceserator tetramethylthiuram disulfide (Vulcanization accelerator TMTD)；
The vulcanizing agent is preferably sulphur.
The advantages and effects of the present invention are:
Base rubber used in the present invention is the group of natural rubber (SCR5), butadiene rubber (BR9000) and 60 mesh natural rubber powder
Object is closed, the natural rubber powder of filling reduces raw material usage, increases the volume of product, it is several that tire glue powder is mixed in rubber product
It will not influence the tensile strength, elongation at break and wear-resisting property of rubber product itself, even improve rubber product
Wearability, fatigue durability and tearing toughness, it is important that it is cheap and easy to get, save production cost；Rosin is added, improves system
The glossiness of product；Dispersing agent, which is added, can improve the dispersibility of carbon black, increase the mechanical property of product；The paraffin and amides of addition
Slipping agent cooperation can form coating of wax film in product surface, and lubricity is fine, can be preferably in profit certainly in assembly and use
Sliding state, reduces friction.
Specific embodiment
