Abstract
The invention relates to a wear resistant sole material. The wear resistant sole material comprises, by weight, 35-45 parts of EVA, 4-8 parts of styrene butadiene rubber, 1-8 parts of butadiene rubber, 1-4 parts of a vulcanizing agent, 2-5 parts of a reinforcing agent, 1-4 parts of an activator, 1-4 parts of an accelerant and 0.5-3 parts of a foaming agent. The wear resistant material greatly improves the wear resistance of a sole without influencing the elasticity, the resilience, the portability or the like of the sole, and also has the advantages of non-toxicity, no pollution, safety and environmental protection.
Description
Technical field
The present invention relates to a kind of Wear-resistant sole material.
Background technology
Wear resisting property is an important indicator of rubber item, such as rubber tyre, sealing member, travelling belt, piston ring and sole etc., in use certainly lead to friction and wear, these are all closely related with material failure and security. and China is one and produces footwear big country, consumption is also very considerable, improve the wear resistance of rubber soles, can bring appreciable economic benefit and social benefit.
New abrasion-resistant material development has two distinguishing features: the firstth, by single-material, to matrix material, developed, and in material, add the strongtheners such as particle, whisker and fiber to improve wear resistance; The secondth, adopt sufacing manufacture in modern age high-performance abrasion-proof to damage material.At present, people relatively tend to the research and development of matrix material: employing dry method calendering process adds 5～10% rare earth cerium oxide in rubber, has improved the wear resistance of rubber; Add a certain proportion of silicon nitride in ethylene-propylene rubber(EPR), improved its wear resistance; Add 1～1.5 portion of super wear-resisting strengthening agent of NSN powder rubber in the corrugated tube that is EPDM at material of main part of nano level amorphous silicon nitride (median size 20nm) development of the application autonomous production of Hefei Kai Er nanometer company, obtain good result.
Because the dry method calendering process is simple, convenient for production, but the rare earth particle can not be evenly distributed in rubber well, when especially content of rare earth is high, the rare earth particle easily produces local the reunion and causes stress concentration, and sample strength is descended, and wear resistance reduces.The most important is that the price comparison of rare earth is high, adds rare earth oxide in sole, has improved the cost of footwear product.Simultaneously, because the consistency between inorganics commonly used and organism is poor, therefore be difficult to guarantee to there is good affinity between the two-phase interface of matrix material, when add-on is greater than certain value, the wear resistance of material descends on the contrary. in gum cement, form " tiny crack " around particle surface in not enough to wedding agent adhesive bond power due to large-size particle in the gum cement in sulfidation, abrasive particle is combined control not firm with rubber.
Summary of the invention
For the deficiencies in the prior art, one of purpose of the present invention is to provide a kind of Wear-resistant sole material, described Wear-resistant sole material is under the prerequisite of the elasticity that does not affect sole, Restoration, portability and other performances, increased substantially the wear resistance of sole, and nontoxic pollution-free, safety and environmental protection.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of Wear-resistant sole material, it comprises following raw material by weight:
Preferably, described Wear-resistant sole material comprises following raw material by its parts by weight:
The parts by weight of described EVA are for example 36,37,38,39,40,41,42,43 or 44.
The parts by weight of described styrene-butadiene rubber(SBR) are for example 4.2,4.4,4.6,4.8,5,5.2,5.4,5.6,5.8,6,6.2,6.4,6.6 or 6.8.
The parts by weight of described cis-1,4-polybutadiene rubber for example 1.3,1.6,1.9,2.2,2.5,2.8,3.1,3.4,3.7,4,4.3,4.6,4.9,5.2,5.5,5.8,6.1,6.4,6.7,7,7.3,7.6 or 7.9.
The parts by weight of described vulcanizing agent are for example 1.2,1.4,1.6,1.8,2,2.2,2.4,2.6,2.8,3,3.2,3.4,3.6 or 3.8.

The parts by weight of described promoting agent are for example 1.2,1.4,1.6,1.8,2,2.2,2.4,2.6,2.8,3,3.2,3.4,3.6 or 3.8.
The parts by weight of described promotor are for example 1.2,1.4,1.6,1.8,2,2.2,2.4,2.6,2.8,3,3.2,3.4,3.6 or 3.8.
The parts by weight of described whipping agent are for example 0.7,0.9,1.1,1.3,1.5,1.7,1.9,2.1,2.3,2.5,2.7 or 2.9.
The vulcanization of rubber, the curing system usually be comprised of vulcanizing agent, promotor and promoting agent forms.Linear macromolecule chain in rubber, under chemical action, by being formed by connecting as the cancellated process in space of chemical bond, is called sulfuration (curing, crosslinked).Make rubber that crosslinked chemical substance occur, be called vulcanizing agent.Preferably, vulcanizing agent of the present invention is sulphur.
Activating agent for rubber can promote sulfuration, activation and the reinforcement anti-aging effect of rubber, can strengthen sulfidation, reaches stability, processing safety raising, the decrease fraction defective, improve rubber item resistance to tearing, wear resistance, simultaneously, can improve anti-aging, the anti-crawl agentdefiection fragility energy of rubber product.Stearic acid selected by promoting agent of the present invention or/and Zinic stearas all can commercially availablely obtain.Two kinds of promoting agents can be used alone, and also can mix use, mix to use to obtain obvious synergy.
Described strengthening agent is selected from the mixture of a kind of in carbon black N234, carbon black N220 or carbon black N330 or at least two kinds, described mixture is the mixture of carbon black N330 and carbon black N220 for example, the mixture of carbon black N330 and carbon black N234, the mixture of carbon black N330, carbon black N220 and carbon black N234.Described carbon black N234 is fine intermediate super abrasion furnace black high structure, and carbon black N330 is high abrasion furnace black(HAF), and carbon black N220 is that height is stretched medium super abrasion furnace black surely.Carbon black can make rubber have high wear resistance, tensile strength etc. as strengthening agent.Association reaction between carbon black and rubber is the fundamental cause of carbon black to reinforcing rubber.At first the wetting carbon black of the rubber molecule of viscous state, then well be adsorbed on carbon blacksurface, forms physical bond.Carbon black of the present invention is the nano level carbon black, nano level carbon black uneven surface has a large amount of edges and fin, the active site of these high surface energies causes, with polymkeric substance, very strong physics/physics chemical action is arranged, the interaction of polymer surfaces is also strengthened thereupon, so just increased the contacted probability of polymer segment and carbon blacksurface, the black-reinforced effect strengthens.Three kinds of carbon blacks can be used alone, and also can mix use, mix to use to obtain obvious synergy.
In order to reduce curing temperature, shorten curing time, improve the physical and mechanical properties of sulfide, during sulfur cross-linking, must add vulcanization accelerator.Promotor of the present invention is selected from the mixture of a kind of in accelerant CZ, Vulcanization accelerator TMTD, vulkacit D, accelerator DZ or accelerant NOBS or at least two kinds.Described mixture is the mixture of accelerator DZ and accelerant NOBS for example, the mixture of vulkacit D and Vulcanization accelerator TMTD, the mixture of accelerant CZ and accelerant NOBS, the mixture of accelerator DZ and vulkacit D, the mixture of Vulcanization accelerator TMTD and accelerant CZ, the mixture of accelerant NOBS, accelerator DZ and vulkacit D, the mixture of Vulcanization accelerator TMTD, accelerant CZ and accelerant NOBS, the mixture of accelerator DZ, vulkacit D, Vulcanization accelerator TMTD and accelerant CZ.Five kinds of vulcanization accelerators can be used alone, and also can mix use, mix to use to obtain obvious synergy.
Described whipping agent is warm whipping agent in DX-74MT.
Compared with the prior art, the present invention has following beneficial effect:
High-abrasive material of the present invention makes sole under the prerequisite of the elasticity that does not affect sole, Restoration, portability and other performances, has increased substantially the wear resistance of sole, and nontoxic pollution-free, safety and environmental protection.
