Abstract
A novel rubber material being high in a wear-resistant performance includes following raw materials, by weight, 9 kg of ethylene-propylene rubber, 9-11 kg of hot-cracked carbon black, 1-2 kg of wear-resistant carbon black, 3-4 kg of calcium carbonate, 0.1-0.3 kg of an anti-aging agent polyethylene glycol, 0.15-0.3 kg of a dispersing agent polyethylene wax, 0.05-0.1 kg of an accelerant zinc dimethyldithiocarbamate, 0.1-0.2 kg of a vulcanizing agent sulfur, and 0.15-0.3 kg of a flame retardant ammonium polyphosphate. With the carbon black as a filling material being filled in the ethylene-propylene rubber at a large amount, not only is hardness of the rubber sealing material increased and is production cost of the rubber sealing material reduced, but also the carbon black greatly influences the physical characters of the rubber sealing material. When the hot-cracked carbon black is filled individually, only the objects of increasing the hardness and reducing the production cost are achieved, and when a less amount of the wear-resistant carbon black, which is high in activity, is added, the rubber material is significantly improved in wear resistance when being compared with the novel rubber material simply filled by the hot-cracked carbon black.
Description
Technical field
The present invention relates to rubber packing material, be applied to the wear resisting property improving rubber packing material.
Background technology
The preparation method of current rubber packing material adopts second third glue to be basic rubber raw material, with the lower thermal black of a certain amount of activity as raw material, through banburying, open refining, sulfuration process is prepared from, the feature of this carbon black is that particle is thicker, heat-dissipating is low, compression set is low, can fill in a large number, a large amount of filling can improve rubber hardness and can reduce sizing material cost, but adopts the carbon black that single activity is lower, can not increase the wear resistance of rubber packing material, therefore prepared rubber packing material wear resistance is lower.
Summary of the invention
The object of this invention is to provide a kind of Novel rubber material of high-wear resistance, improve the antiwear characteristic of rubber packing material.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of Novel rubber material of high-wear resistance, preparing in the lower thermal black of activity that rubber packing material uses, add a small amount of active higher abrasion resistant carbon black mixing, raw material weight compares: second third glue 9KG, thermal black 9 ~ 11KG, abrasion resistant carbon black 1 ~ 2KG, calcium carbonate 3 ~ 4KG, anti-aging agent polyoxyethylene glycol 0.1 ~ 0.3 KG, polyethylene of dispersing agent wax 0.15 ~ 0.3KG, promotor ziram 0.05 ~ 0.1KG, vulcanizing agent sulphur 0.1 ~ 0.2KG, fire retardant gathers phosphorus ammonium fat 0.15 ~ 0.3KG.
Above-described elastomeric material, raw material weight compares: second third glue 9KG, thermal black 10KG, abrasion resistant carbon black 1.5KG, calcium carbonate 4KG, anti-aging agent polyoxyethylene glycol 0.2KG, polyethylene of dispersing agent wax 0.2KG, promotor ziram 0.1KG, vulcanizing agent sulphur 0.15KG, fire retardant gathers phosphorus ammonium fat 0.2KG.
The effect that the present invention reaches is: carbon black is as the weighting material of second third glue, a large amount of filling not only increases the hardness of rubber packing material and reduces production cost, and it is larger on the physical property impact of rubber packing material, simple filling thermal black, only play and increase the object that hardness reduces production cost, and after adding the higher abrasion resistant carbon black of a small amount of activity, the wear resistance of rubber packing material is obviously than high when adding merely thermal black.
Embodiment
