Abstract
An external-layer low-hardness rubber fender comprises the following raw materials, by weight, 55-65 parts of natural rubber, 35-45 parts of synthetic rubber, 4-5 parts of zinc oxide, 2.5-3.5 parts of stearic acid, 1.6-2.2 parts of a promoter, 1.4-2.2 parts of a vulcanizing agent, 2.5-4.5 parts of an antioxidant, 20-40 parts of a reinforcing agent, 10-25 parts of a softener, and 1-3 parts of an adhesive, so the physical and mechanical performances, the abrasion resistance, the flexing resistance, the natural ageing resistance, the oil resistance and the seawater resistance of the rubber material having the above composition are best, and the Shore hardness is 36-42, thereby the service life of the fender is improved, and the rubber material is especially suitable for the use in the rubber fender production industry.
Description
Technical field:
The present invention relates to a kind of rubber fender, particularly a kind of outer layer low-hardness rubber fender.
Background technology:
At present, the rubber fender of domestic production adopts natural rubber and synthetic rubber and usefulness, doses strengthening agent, anti-aging agent, promoting agent, vulcanizing agent, tenderizer etc., behind the rubber mixing machine mixed refining process, forming method by different processes through sulfuration, and the rubber size hardness that rubber fender adopts is identical, sizing material Shao Er hardness is at the 58-80 degree, there is the outer layer glue much higher hard, to boats and ships surface injury, affects Ship Life.
Summary of the invention:
It is low that purpose of the present invention just provides a kind of outer layer rubber fender hardness, and elasticity is high, can reduce the outer layer low-hardness rubber fender that the rigidity between fender and the boats and ships connects.
The object of the present invention is achieved like this: a kind of outer layer low-hardness rubber fender is characterized in that it is made of by weight following raw material: natural gum 55-65 part, synthetical glue 35-45 part, zinc oxide 4-5 part, stearic acid 2.5-3.5 part, promotor 1.6-2.2 part, vulcanizing agent 1.4-2.2 part, anti-aging agent 2.5-4.5 part, strengthening agent 20-40 part, tenderizer 10-25 part, tackiness agent 1-3 part.
Zinc oxide of the present invention is a kind of in active zinc flower or the nano zine oxide.
The present invention is characterized in that described promotor is a kind of in the thiazolesulfenamide class promotor.
What vulcanizing agent of the present invention was rubber with in the insoluble sulfur is a kind of.
Anti-aging agent of the present invention is one or both in the p phenylenediamine type antioxidant.
Strengthening agent of the present invention is one or both in fast extrusion and the high wear-resistant carbon black.
The present invention is characterized in that described tenderizer is a kind of in the aromatic hydrocarbon tenderizer.
The present invention is characterized in that described tackiness agent is a kind of in the silicane tackiness agent.
The present invention compared with prior art has following advantage:
Because the rubber fender that has adopted following raw material to form by weight: natural gum 55-65 part, synthetical glue 35-45 part, zinc oxide 4-5 part, stearic acid 2.5-3.5 part, promotor 1.6-2.2 part, vulcanizing agent 1.4-2.2 part, anti-aging agent 2.5-4.5 part, strengthening agent 20-40 part, tenderizer 10-25 part, tackiness agent 1-3 part, thereby, combine natural rubber and elastomeric different performance, make physical and mechanical properties and the wear resistance of sizing material, flexible resistance, anti-natural weathering, oil-proofness and sea water resistance reach optimum regime, Shao Er hardness is the 36-42 degree, adopt accelerant NOBS in the prescription, make sizing material have excellent coke burning performance, and the smooth phase of vulcanization curve is long, the tackiness agent that adds some amount in the prescription, improved the bonding strength of outer layer rubber and the internal layer rubber of different hardness, thus the work-ing life of having improved fender.
Embodiment:
