Abstract
The invention discloses a mortar wet-grinding resistant rubber material and a preparation method thereof. The wear-resistant synthetic rubber material mainly comprises natural rubber, butadiene rubber, butadiene styrene rubber, chlorinated polyethylene rubber, oil or fat dioctyl phthalate (DOP), polytetrafluoroethylene, nanographite, oligomer ester, an accelerating agent, a reinforcing agent, an anti-reversion agent, a vulcanizing agent and fillers. The wear-resistant synthetic rubber material with Shore hardness of more than 60 and Akron abrasion (cm<2>) of 0.030 g is prepared by performing processes of plastication, mixing and the like on the raw materials. The wear-resistant synthetic rubber solves the problem of short using time caused by that machine parts used for conveying cement mortar, pumping concrete and the like are susceptible to wear and corrosion.
Description
Technical field
What the present invention relates to is a kind of elastomeric material, and particularly a kind of moisture-proof rubber milling material is exactly a kind of anti-mortar wet-milling elastomeric material specifically.
Technical background
In the building engineering construction process, the increasing mortar handling equipment that uses is carried building mortar or concrete, such as mortar pump, Mortar spraying machine etc., the material such as quartz sand, Wingdale that contains a large amount of high rigidity in building mortar or the concrete, wearing and tearing to metal parts are very serious, therefore more and more equipments manufacturing concern selects abrasive rubber alternative metals material production equipment parts for use, to alleviate the wearing and tearing to equipment unit of building mortar or concrete.
The Akron abrasion of tradition elastomeric material is generally 0.65-0.95g/cm
2, rubber layer is easy to wearing and tearing, cause come off, resistance to air loss descends and cause service life of equipment short.After in elastomeric material, adding some functional materialss, can improve the wear resisting property of elastomeric material; Such as adding meridianal rubber tyre, be improved largely for the wear resistance dry environment or neutral rainwater environment under, but, also rarely have report for improving the rubber abrasive-resistance of use under high alkalinity such as sand-cement slurry and concrete and aqueous environments.
Summary of the invention
The objective of the invention is to provide a kind of elastomeric material of anti-mortar wet-milling, it can make the Akron abrasion of elastomeric material in strong basicity water-based environment by 0.65-0.95g/cm
2Be reduced to 0.2g/cm
2Thereby, prolonged work-ing life of equipment significantly.
For addressing the above problem, the present invention is achieved in that
A kind of anti-mortar wet-milling elastomeric material, produce according to a conventional method, it is characterized in that by following substances in percentage by weight formulated: natural rubber 10-20%, cis-1,4-polybutadiene rubber 10-20%, styrene-butadiene rubber(SBR) 10-20%, chlorinated polyethylene rubber 5-8%, lipid DOP5-8%, tetrafluoroethylene 1.5-3%, lubricant 1-10%, oligomerisation agent 8-10%, promotor 3-5%, anti-reversion agent 1-3%, vulcanizing agent 1-5%, stopping composition 10-25%.
Adopt nano-graphite as lubricant among the present invention, reduce the wearing and tearing of mortar to the rubber accessory, the nano-graphite lubricant addition of You Huaing is 1-10% in the present invention.
