Description
Technical field
A kind of natural rubber for the dynamic multiplying power that is lower the present invention relates to technical field of rubber material more particularly to high temperature resistant low pressure
Material.
Background technology
Natural rubber has good elasticity, and physical mechanical property and hysteresis loss are small so that rubber product has good
Good damping property, wearability and durability, is widely used in various automobile shock products.Meanwhile natural rubber is as a kind of insatiable hunger
And polymer, molecular flexibility is good, can assign natural rubber preferable cryogenic property.However, this unsaturated structure also at
For the weak spot of performance loss under high temperature.Under hot environment, rubber can change first at unsaturated place, material occur
It can decline, such as physical mechanical property and compression set after aging, natural rubber conventional heat refractory temperature be caused there was only 70 DEG C of left sides
It is right.As major main engine plants are increasingly stringenter natural rubber material high temperature (100 DEG C) performance requirement, therefore, natural rubber is solved
Glue high temperature resistant condition is also just at extremely urgent thing.Meanwhile the comfortableness and security in driving procedure are also major host
Factory's moment pay close attention to the problem of, in order to improve such case, can by reduce to the maximum extent the dynamic property of rubber material come
It realizes.The project verification of this item purpose, which is to improve natural rubber physical mechanical property difference and compression set are big at high temperature, asks
Topic, and the ratio between sound rigidity for reducing rubber material (dynamic multiplying power), improve the comfort of car steering and carriage, driving it is steady
It is qualitative, noise is reduced, the service life of product is extended.
Invention content
For existing problem, it is an object of the invention to propose that a kind of processing performance is good, good physical properties, resistance to height
Temperature, low pressure change and low dynamic multiplying power natural rubber products material and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of high temperature resistant low pressure is lower the natural rubber material of dynamic multiplying power, is made of the raw material of following parts by weight：Natural rubber
Glue 70-85, butadiene rubber 15-30, carbon black 40-55, indirect process zinc oxide 4-6, stearic acid 1-2, anti-aging agent RD 1-2, anti-aging agent
4010NA 1-2, antioxidant 4020 1-2, anti-scorching agent CTP 0.2-0.3, dispersant 1-2, protection wax 2-3, insoluble sulfuy IS-
60 0.5-4, DTDM 0.5-1.5, accelerant CZ 0.5-2, TBzTD 0.1-3.
The raw rubber trade mark can be selected from No. 5 standard natural rubbers, SVR 3L, 10CV, CV60, BR9000, Buna in the present invention
It is one or more in CB565T, SBR1502 and smoke sheet rubber, by performance Comparability test, comprehensive various aspects of performance, present invention choosing
Selecting property, using the paralled system of SVR 3L natural gums and Buna CB565T butadiene rubbers, the raw rubber relative to other trades mark comes
It says, the quality higher of both raw rubbers of SVR 3L and Buna CB565T can provide physically better mechanical performance, meanwhile, it is maximum
The use of peptizer in formula is reduced to limit, the high gum content as possible in guarantee system improves the elasticity of rubber compound；Ensureing
Under the premise of material high temperature resistant low pressure becomes, system is promoted using low-sulfur height.By the above measure, not only so that natural rubber material
Material can obtain dynamic multiplying power as small as possible, meet the dynamic performance requirements of rubber damping product；It can also be in the permanent change of compression
Also larger improvement is obtained in shape.
The present invention select low-sulfur height promote or sulfur-donor system, wherein accelerating agent can select accelerant CZ, NS, DM, TMTD,
One or several kinds in TMTM and TBzTD, the present invention are used with using a variety of, selectively use two sulphur of tetra-benzyl thiramization
(TBzTD), it both may be used as sulfur-donor and can also act as accelerating agent.TBzTD possesses numerous excellent performances, rate of cure is fast,
Scorch safe performance is good, sizing material heat resistance is good, while a kind of still fast accelerator of safety, green.
Carbon black can be selected from carbon black N110, carbon black N220, carbon black N330, carbon black N339, carbon black N550, carbon black in the present invention
N660, carbon black N774, carbon black N990 and spray carbon black.Equally under the premise of ensureing low dynamic multiplying power, by performance Comparability test,
Preferential selection spray carbon black, spray carbon black particle is relatively thick and can largely be filled in sizing material, and processing performance is good, vulcanizate
It is elastic big, heat is low, deformation is small, low temperature performance well, stress at definite elongation are higher and at low cost.Using the measure of above series of, obtain
While obtaining preferable high temperature resistance, excellent compression set performance can also be obtained, major automobile main frame maker pair is met
The requirement of natural rubber material applied at elevated temperature.
