Description
Technical field
It is particularly a kind of defeated suitable for fields such as metallurgy, harbour, building materials and mines the present invention relates to conveyer belt technical field
Send the high resiliency of lump material, wear-resistant, shock resistance conveyer belt and preparation method thereof.
Background technology
Conveyer belt is the important component of ribbon conveyer, and its value accounts for the 40% of conveyer, is the master of conveyer
Want accessory, transported material have continuity and it is efficient the features such as.No matter indoor and field, long-distance and short distance, level and inclination,
Conveying, dispersion and the concentration of material are capable of achieving under various different working conditions.Compared with automobile, railway transportation, belt conveying
Mode shortens transportation range, reduces construction costs and cost of transportation.The framework material of current conveyer belt to nylon and gathers
Ester develops, and nylon and polyester backbone material have accounted for more than 80%, big, the resistance to flexion of synthetic fibers belt carcass strength, meet it is wet does not go mouldy, solve
Low, belt carcass is cross-section for duck framework material strength of having determined, glue and cloth and cloth and the quality problems of cloth delamination.But, prior art
In, the rubber cover poor flexibility of conveyor belt surface, not wear-resisting, service life are short.As the consumable accessory of ribbon conveyer, conveyer belt
These defects drastically influence the conveying effect and service life of ribbon conveyer.How the structure of existing conveyer belt is improved,
Improve the elasticity and wearability of its surface covering rubber, improve its service life, be current to economize on resources, reduce use cost
It is badly in need of the technical problem for solving.
The content of the invention
In order to solve the above technical problems, the present invention proposes a kind of high resiliency, wear-resistant, shock resistance conveyer belt and its preparation side
Method.
The technical proposal of the invention is realized in this way：
A kind of high resiliency, wear-resistant, shock resistance conveyer belt, including belt carcass and rubber cover, belt carcass are NN canvas, EP canvas or NN/
EP canvas, rubber cover includes the component of following parts by weight：50~80 parts of natural rubber, 20~50 parts of synthetic rubber, sulphur 1.6

It is further preferred that the physical property requirements of rubber cover are：Pull apart strength >=18Mpa, elongation at break >=
450%, wear loss≤90mm3, 56~65A of hardness（Shao Er）.
It is further preferred that synthetic rubber is butadiene rubber or butadiene-styrene rubber.
It is more highly preferred to, reinforcing agent is the mixture of intermediate super abrasion furnace black N220 or intermediate super abrasion furnace black N220 and N330.
Highly preferred, softening agent is the mixture of coumarone indene resin and aromatic naphtha.
The invention allows for above-mentioned high resiliency, wear-resistant, shock resistance conveyer belt preparation method, prepared in advance during preparation
Rubber cover, the preparation method of rubber cover is as follows：
After natural rubber is through over-mastication, in banbury with synthetic rubber and refine, adding small powder, reinforcing agent, softening agent is carried out
One section of mixing, small powder includes zinc oxide, stearic acid, antiwear additive and age resistor, and one section of rotating speed of mixing is 40r/min, floating weight
Pressure 0.6Mpa, rubber 60s, small powder 20s, reinforcing agent 70s, softening agent 50s, 140 DEG C of dumping slices；Park more than 16 hours,
Two-stage mixing, two-stage mixing rotating speed 30r ∕ min, ram piston pressure are carried out to sulphur, accelerator is added in one section of elastomeric compound
0.6MPa, one section of elastomeric compound and sulphur promote 90s, rise the s of bolt 20,110 DEG C of dumping slices.
Compared with prior art, the present invention has the advantages that：
1st, conveyor belt surface is smooth, and defect is little, with impact-resistant high resiliency, good fatigue performance and super large
Strongly, rubber cover is difficult to collapse block, tear in sharp keen lump material transportation, is particularly well-suited to large-scale building stones, harbour
HI high impact, the use of drop conveyer high；
2nd, conveyer belt abrasiveness is extremely low, wear loss≤90mm3Even if, the long-term strong abrasive conditions in coarse block or shot-like particle
Under use, itself abrasion it is also little；
3rd, long service life, is at least 2-3 times of duck conveyor belt；1.2-1.3 times of low cost, only duck conveyor belt, pole
The earth improves cost performance；
4th, production process is green, pollution-free, meets the requirement of sustainable development.
The present invention solves the contradiction that high resiliency can not have concurrently with low abrasion in the prior art so that conveyer belt has simultaneously
Standby high resiliency and low abrasion, drastically increase the service life of conveyer belt, reduce the use cost of conveyer belt.
