Description
Technical field
The present invention relates to tire preparation technical fields, and in particular to a kind of low-heat-generation glue core and its preparation method and application.
Background technique
In rubber industry, the main reinforcing agent of traditional rubber is based on carbon black type filler.But since carbon black is producing
Can do great damage in the process to ambient enviroment, meanwhile, carbon black as rubber reinforcing filler vulcanized rubber obtained there is
The problems such as heat is higher, elasticity is low, this is unfavorable for the service life for improving rubber product, as the automobile tire under high speed is frequent
Explosion occurs due to heat and scraps in advance, people are seeking always a kind of function additive and are replacing part carbon black, preparation
The vulcanized rubber of low-heat-generation, high fatigue life is for tire tread, sidewall and other rubber components out.
Currently, using remaining filler that part carbon black is replaced to reduce tire heat as relatively conventional technology, but replace
Filler can affect the mechanical performance of rubber tyre, reduce its wearability, and then the use of tire is influenced in terms of remaining
Service life.
Therefore, how a kind of rubber tyre glue core with good mechanical strength and low-heat-generation is provided, is this field skill
Art personnel's urgent problem to be solved.
Summary of the invention
In view of this, the present invention provides a kind of low-heat-generation glue core and preparation method thereof, by improve raw material proportioning and

The beneficial effect of above-mentioned optimal technical scheme is: the internal structure of fume colloidal silica particle is the close silicon of arrangement
Sour tridimensional network, this structure can make hard charcoal black track producing particle hygroscopicity lower, and adsorption ability is strong, has to rubber good
Reinforcing effect.
Preferably, the silane coupling agent is double-[(triethoxysilicane alkyl)-propyl] tetrasulfide or triethoxy mercapto
Propyl silane.
The beneficial effect of above-mentioned optimal technical scheme is: double-[(triethoxysilicane alkyl)-propyl] tetrasulfide coupling agent
Have a wide range of application and performance is good, triethoxy mercapto propyl silane has good anti-coke-burning capacity and the physical property shadow to rubber
It rings less, and can also increase the heat-resistant aging of rubber.
It is another object of the present invention to provide a kind of preparation methods of low-heat-generation glue core, comprising the following steps:
(1) natural rubber will be weighed by mass fraction, be transmitted to mixer later and be plasticated, it is then allowed to stand 18~for 24 hours；
(2) it is added in the natural rubber after Xiang Suoshu step (1) is plasticated by the weighed carbon black of mass parts ratio and is carried out equal
Even mixing；
(3) it will uniformly be mixed by the weighed white carbon black of mass parts ratio with silane coupling agent；
(4) mixture in the step (3) is transmitted into mixer, is mixed with the mixture in the step (2)
Mixing after uniformly, is then made film；
(5) manufactured film is sent into extruder and is pressed into glue core shape.
Preferably, banbury rotating speed is 45~55r/min, plasticating temperature 140 during plasticating in the step (1)
~155 DEG C, plasticate 11~15min of time.
The beneficial effect of above-mentioned optimal technical scheme is: natural rubber, which is plasticated, can be such that rubber cuts off under the action of machinery point
Subchain reduces Mooney viscosity, improves technological operation and processing performance, so that rubber is temporarily lost with elasticity and increases its plasticity,
To meet the requirement of the technique in manufacturing process, other other auxiliary agents is made to be easy uniformly to be reacted with rubber mix.
Preferably, banbury rotating speed is 55~60r/min in the step (4), and smelting temperature is 60~80 DEG C, when mixing
Between 13~17min.
The present invention also provides can a kind of application of low-heat-generation glue core, be applied to production All-steel tire fetus, it is specific to make
Preparation Method are as follows: glue core is wrapped into benefit with rubber, wire loop, inner liner and rim of the mouth and belt combines up to fetus.
In conjunction with above scheme, compared with prior art, the invention has the benefit that providing a kind of low-heat-generation glue core
The application of formula and preparation method thereof and glue core obtained by optimizing the proportion of stuffing by carbon black and white carbon black, and improves
Preparation process, by rationally controlling charging sequence and reaction condition in preparation process so that rubber obtained not only have it is good
Good mechanical performance also has low-heat-generation, is used for production All-steel tire fetus, effectively extends the use of All-steel tire
It in the service life, effectively prevents various because dangerous caused by damaged tyres in driving process, has highly application value.
