Description
Technical field
The present invention relates to polyurethanes technology field, more particularly to a kind of polyurethane clad on forklift hub surface.
Background technology
Fork truck needs crotch stretching to tray bottom in use, is moved integrally under the drive of fork truck wheel,
This bearing capacity to fork truck wheel requires high, and fork truck wheel includes wheel hub and is coated on the polyurethane clad of hub surface, mesh
The preceding wheel hub weight due to 5-10t fork trucks reach more than 40kg, after loading cargo, is manually transported to mounting plate and subsequently
90 ° of turn work of process, its labor intensity is big, and since workpiece quality is big, to the polyurethane clad wear resistance on top layer
It is required that high, there are serious security risk.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of polyurethane cladding on forklift hub surface
Layer, has excellent wear-resisting property, and suitable for persistently being used under high abrasive conditions, and the adhesive strength between core wheel
Height, is not likely to produce sliding friction, while tensile strength is high, fire resisting, corrosion-resistant.
A kind of polyurethane clad on forklift hub surface proposed by the present invention, its raw material include by weight：Polyurethane
100-140 parts of rubber, 30-40 parts of butadiene-styrene rubber, 10-20 parts of natural rubber, 10-18 parts of nitrile rubber, 5-11 parts of vulcanizing agent, weight
25-45 parts of matter calcium carbonate, 10-20 parts of graphene, 10-18 parts of nano-bentonite, 4-8 parts of vulcanization accelerator, 2-4 parts of pine tar,
2-4 parts of antiscorching agent, 2-4 parts of antioxidant, 2-4 parts of plasticizer, 2-4 parts of softening agent.
Preferably, vulcanizing agent includes by weight：4-8 parts of cumyl peroxide, 1-3 parts of tert-butyl hydroperoxide.
Preferably, vulcanization accelerator includes by weight：2-4 parts of 2- mercapto imidazolines, tetramethylthiuram disulfide
2-4 parts.
With common rubber phase ratio, the present invention has excellent wear-resisting property, and suitable for continuing under high abrasive conditions
Use, and tensile strength is high, it is fire resisting, corrosion-resistant.
The present invention is compounded using polyurethane rubber and butadiene-styrene rubber, natural rubber, nitrile rubber, and synergistic effect, can improve
Adhesive strength between the present invention and core wheel, bond strength is high, is not likely to produce sliding friction, service life is grown, and peroxidating two
Isopropylbenzene, tert-butyl hydroperoxide can promote to form cross-linked network between polyurethane rubber, butadiene-styrene rubber, natural rubber, nitrile rubber
Shape structure, bond strength is high, and wear-resisting property is excellent, and good toughness, and powdered whiting, graphene, nano-bentonite can be abundant
It is dispersed in system, on the basis of polyurethane rubber additive amount is reduced, reduce cost, hardness is high, and wearability is outstanding, makes
The present invention is uniformly and intimately fitted in core surfaces, and composite performance is good, and gained fork truck wheel is corrosion-resistant, wear-resistant, and cost is low
It is honest and clean.
