Abstract
The invention relates to a novel conductive and flame retardant mining tread mix formula of a solid tyre and a production process. 5-8% of 60-150-mesh swarf is doped into the tread mix, so that the conductive performance and the wear resistance of the tyre are improved. A certain proportion of an environmental flame retardant is added into the tread mix formula, and chloroprene rubber which is excellent in flame retardance and natural rubber which is excellent in comprehensive performance are simultaneously used, so that the problem that the existing mining solid tyre is inflammable and poor in conductivity is solved. The tyre can be widely applied to occasions related to high-temperature combustible environments in mining industry, coal mining industry, metal smelting industry and the like.
Description
Technical field
The present invention relates to mining solid tyre, particularly the fire-retardant new type mining solid tyre tread mix formula of a kind of conduction and production technique.
Background technology
Since reform and opening-up, national economy increases fast, and " scientific and technical innovation, autonomous innovation " has become the main flow of current domestic industry development, and China's industry is just progressively to the future development of intensive style, energy-saving and emission-reduction, low-carbon (LC).Along with industrial vehicle and the development of other purpose-built vehicle, more and more higher to the requirement of tyre performance.Solid tyre is because having higher portative power, smooth ride, resistance to thorn, being widely used on the slow-moving vehicles such as engineering truck without the need to the frequent feature such as repairing.Be subject to the favor of consumers in general, for infinite commercial opportunities are brought in solid tyre market.The fast development of Domestic Automotive Industry, mining industry, coal mining industry, Metal smelting industry and the needs of the aspect such as fire-fighting, isolation inflammable articles, propose requirements at the higher level to the flame-retardant conductive performance of rubber product, present quick growing trend to its demand.But current most synthetic rubber is all flammable or inflammable glue kind, and wear resistance is bad, brings potential fire hazard thus, brings inconvenience to productive life.Therefore, the flame retardant resistance of these industry special tyre products seems very urgent and important.In order to address this problem, the technician of R&D institution and enterprise is constantly exploring, is studying, wish to develop the fire-retardant novel solid tyre of a kind of conduction, although make some progress, in practice, still there is the technical barrier not yet overcome.
Summary of the invention
The object of the invention is to overcome above deficiency, the fire-retardant new type mining solid tyre tread mix formula of a kind of conduction and production technique are provided, in tread rubber, mix 60 order-150 order swarfs of 5-8%, improve conductivity and the wear resistance of tire; A certain proportion of environment friendly flame retardant is added in tread glue formula, the neoprene of excellent flame retardancy is adopted to resemble the natural rubber of glue and excellent combination property and use, solve the problem of the inflammable and poorly conductive of existing mining solid tyre, this tire can be widely used in the place that mining industry, coal mining industry, Metal smelting industry etc. relate to high temperature combustible environment.
The technical solution adopted for the present invention to solve the technical problems is: the fire-retardant new type mining solid tyre of a kind of conduction, and this tire tread compound adds following material composition: natural rubber 13-18%, chloroprene rubber 35-40%, graphitized carbon black 20-25%, fire retardant 8-12.5%, promoting agent 3.5-4.5%, promotor and anti-aging agent 1.5-2%, swarf 5-8%, other filler about 3%.
Technical process:
1, the preparation of the solid tread mix of fire-retardant new type mining is conducted electricity: after being mixed in Banbury mixer by above-mentioned material except swarf, mix swarf on a mill until;
2, tire building: the green tyres of batching shaping specific standard weight on forming machine respectively by base rubber, core glue, the order of the solid tread rubber of fire-retardant new type mining of conducting electricity;
3, tyre vulcanization: Hydraulic Station work sulfuration unit upper cover is opened, mould is sent into sulfuration unit indoor, upper cover is closed and is started sulfuration, temperature controls at 120-140 DEG C, and pressure is 11-20MPa, is vented 8-9 time, heat-insulation pressure keeping sulfuration 90min to 20h (different from temperature according to tire specification size sulfide stress), sulfuration terminates, and closes air-supplying valve, discharge residue vapor;
4, tire depanning is got: water bag upper cover is opened in Hydraulic Station work, suspension hook takes out mould, open self-locking device and take out tire, deburring, namely obtained the present invention adopts the flame-retardant conductive automobile solid tyre that the solid tyre tread rubber of flame retardant rubber and novel environment-friendly fire retardant obtains.
In addition: what use in the sizing compound formula of core glue, base rubber is industry general purpose material, manufacture craft is mixer mixing.
The principle of this formula is adopted to be:
Chloroprene rubber outward appearance is sheet or the block of oyster white, beige or light brown, has good physical and mechanical properties, oil resistant, heat-resisting, resistance to combustion, resistance to daylight, resistance to ozone, acid and alkali-resistance, chemical-resistant reagent.Have higher tensile strength, elongation and reversible crystallinity, cementability is good.But chloroprene rubber winter hardiness and package stability poor, electrical insulating property is not good, adopt the chloroprene rubber of excellent flame retardancy and the natural rubber of excellent combination property and use, this phenomenon can be improved, improve stability, mix 60 order-150 order swarfs of 5-8%, conductivity and the wear resistance of tire can be increased, reach the effect that conduction is fire-retardant.
