Description
Technical field
The present invention relates to employed high strength elastic elastomeric material and application thereof on the sports goods, specifically a kind of elastic band elastic band of high-strength rubber material and production thereof.
Background technology
Employed elastic band mostly is elastic woven material and makes on the physical fitness equipment, and its dilatability and elastic force are all less, often can not satisfy the needs of some body-building actions.
How the elastic band that a kind of dilatability is large, the higher and durable elastomeric material of elastic force is made is provided, and is the technical problem that this area will solve.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high strength, high-tension, grease resistance, ageing-resistant high strength elastic elastomeric material and the elastic band of production thereof.
In order to address the above problem, the invention provides a kind of high strength elastic elastomeric material, the each component that it comprises and weight proportion thereof are: natural rubber: 80～100 parts, zinc oxide: 3～5 parts, stearic acid: 0.5～1.0 part, antioxidant 264: 1.0～2.0 parts, sulphur: 1.5～3.0 parts, captax: 0.1～0.5 part, altax: 0.3～0.8 part, SiO
2: 30～50 parts, TiO
2: 0.5～5 part, 0.5 part of iron oxide yellow.
Zinc oxide is activator, the stearic acid processing material, and the hardenability of rubber has been strengthened in zinc oxide and stearic mixing, and sulphur is vulcanizing agent, makes linear molecule pass through sulfide linkage organizer network structure; Promotor is vulcanization accelerator, shortens the curing time of rubber, reduces curing temperature, reduces the consumption of sulphur, improves the rubber physicals.Anti-aging agent is divided into thermo oxidative aging anti-aging agent, anti-ozone ageing anti-aging agent, antifatigue anti-aging agent, ultra-violet radiation resisting anti-aging agent etc., add that various anti-aging agent can improve that rubber is heat-resisting, the effect of oxygen, ozone, variable valency metal ions, mechanical stress, light, energetic ray, and the erosion of other chemical substance and mould etc., slow down be clamminess behind the rubber life-time service, hardening embrittlement or be full of cracks, thereby improve rubber work-ing life.Silicon-dioxide (can be a kind of white carbon black) improves wear resistance, moisture-proof slip energy, the improvement goods thermal deformation behavior of rubber.
Titanium dioxide claims again titanium dioxide, can improve rubber unvulcanizate corrosion resistance nature, anti-microbial property, can be used as toughener by surface treatment, can improve its tensile strength behind the adding rubber.
The manufacture method of above-mentioned high strength elastic elastomeric material, it comprises the steps:
A. plasticate: the natural rubber that weighs up is put in the mill, and thin-pass is 3～5 times under pony roll square, obtains rubber; Natural rubber is processed by the method for mechanical process, chemical method or both and usefulness, to reduce relative molecular weight and the viscosity of natural rubber, improved its plasticity-, acquisition must be mobile, is convenient to process pan feeding.
B. mixing: described rubber is dropped into Banbury mixer, and it is stand-by refine after 1～2 minute taking-up;
C. drop into load weighted SiO to Banbury mixer
2, drop into again through mixing rubber pressurization banburying 8～10 minutes;
D. drop into load weighted zinc oxide, TiO
2, stearic acid, anti-aging agent, pressurization banburying 2～3 minutes;
E. in mill, lower cooling; 24 hours after vulcanization sulphurs, captax and altaxs are practised sheet and namely obtain modification rubber unvulcanizate (finished product) by returning, and also are the high strength elastic elastomeric material.
Described mixing step also can adopt contrary mixed method mixing.
The application of above-mentioned high strength elastic elastomeric material of the present invention in the preparation elastic band namely used above-mentioned high strength elastic elastomeric material and produced elastic band.
The present invention relatively has positive effect with prior art: (1) high strength elastic elastomeric material of the present invention improves its fatigue lifetime greatly, and intensity height, grease resistance corrosive power are strong simultaneously.(2) order of addition(of ingredients) of mixer mixing is rubber usually, small powder, and middle material, aniseed, oil, discharge, this technique powder splashes easily, and it is all influential to environment, health, mixing.The difference of contrary mixed method of the present invention is to put first the material except rubber, after discharging rubber is plunged into, and it is once mixing to put down floating weight.Middle can have a floating weight stirring process of lifting to secondary.The advantage of this compounding process is: 1. the amount of material is full all the time in the banburying chamber, has increased the pressure that is subject in the rubber compounding process, thereby has improved the suffered mechanical shearing effect of sizing material.Can make mixed more even of sizing material.2. owing to be disposable feeding intake, avoided the operating time of step feeding, can save the operating time, raised the efficiency.3. the thermal history that stands in banburying chamber of sizing material is few, and the vulcanization characteristics of sizing material is more stable.4. reduce the operating machine meeting, also just improved the stability of sizing material between the different batches.
