Abstract

The invention relates to a material for sole. The material for the sole is prepared from the following raw materials in percentage by mass: 33 percent of nitrile-butadiene rubber, 8.3 percent of brominated butyl rubber, 5.5 percent of butadiene styrene rubber, 8.3 percent of polyvinyl chloride, 11 percent of dioctyl-phthalate, 22 percent of white carbon black, 2.2 percent of non-slip agent ceramic powder, 0.8 percent of polyvinyl acetal modified phenolic resin, 0.7 percent of phenolic antioxidant, 0.6 percent of paraffin anti-fogging agent, 1.1 percent of vulcanizing agent sulfur powder, 1.1 percent of thiuram accelerator, 3.2 percent of zinc oxide active agent and 2.2 percent of white smoke polyvinyl alcohol active agent. The sole made of the material not only has good non-slip effect, but also is durable.

Description

A kind of material that is used for sole

Technical field

The present invention relates to a kind of material that is used for sole, be specifically related to a kind of anti-slip sole material.

Background technology

Footwear are people's requisite articles for use of going on a journey, the of a great variety of footwear selected for various people, people are also inequality to the requirement of footwear, but non-skid property be people common the requirement, because road surface and easy ways section of rainy day in the ice and snow covering, the not anti-skidding footwear of dress are easy to fall down, the meeting that has so and tumble injury, particularly old man and child Geng Yi tumble injury.The phenomenon that occurs skidding is because the frictional force between road surface and the sole drops to very little, take anti-skidding method normally on sole, to suppress lines at present, but lines can be polished after wearing for some time, still do not have anti-skidding effect, wearing sole in addition has tangible sense of discomfort, and it is relatively more painstaking to walk.

Summary of the invention

In order to solve the problem that exists in the background technology.The invention provides a kind of material that is used for sole, the sole of making of this material is good antiskid effect not only, and durable in use.

The technical solution adopted in the present invention is: this material that is used for sole is made by following raw materials according, and each raw material is calculated by mass percentage: paracril 33%, brominated butyl rubber 8.3%, styrene-butadiene rubber(SBR) 5.5%, polyvinyl chloride 8.3%, dibutyl ester 11%, white carbon black 22%, on-slip agent ceramics powder 2.2%, polyvinyl acetal modified phenolic resins 0.8%, phenol antioxidant 0.7%, antifogging agent paraffin 0.6%, vulcanizing agent SULPHUR POWDER 1.1%, thiuram type accelerator 1.1%, promoting agent zinc oxide 3.2%, white smoke active agent polyvinyl alcohol 2.2%.

Adopt paracril N-41 in the such scheme, its third rare nitrile content is 41%, stronger with composite both polarity of polyvinyl chloride, intermiscibility is better, and both mix its elasticity reduction of back through the processing back, because its polarity is strong, poor flexibility, can strengthen the sticking power (mainly show as the polarity difference between the material, its magnetism is changed, thereby increase the on-slip frictional coefficient) of itself and ground surface contact surface.Brominated butyl rubber BIIR-2255 characteristics are that its resistance to air loss is good, rubber surface micropore and the miniature sucker that resembles during ground contacts one by one.Styrene butadiene rubber sbr 1778 has good processing properties.Have respectively in the above-mentioned high score-Cn ,-Cl ,-Br are the groups that the outermost electron number is more, polarity is strong, be mainly VI, the VII master is bunch elementary composition, and the polarity of whole combination of materials is strengthened all good help, thereby has increased the electric charge adsorptive power between itself and the contact surface.Adding on-slip agent ceramics powder can increase the roughness of material surface, to increase the frictional coefficient of itself and contact surface, consider its reinforcing effect in rubber compounding, therefore adopt the above grain of 120 orders less, if it is too little, the roughness of material surface will reduce again, can influence its skin friction coefficient again.To having selected at the bigger particulate of the following particle diameter of 180 orders.Therefore to sum up 2 influence is chosen in the ceramic particle powder between 120 orders-180 order.The polyvinyl acetal modified phenolic resins increases intermiscibility and the sticking power of each material between in cooperation, other material mainly is to decide according to the vulcanization of rubber and aging of product performance and reinforcing effect thereof, with other vulcanization of rubber prescription basically identical, there are not much differences.

The invention has the beneficial effects as follows: the present invention mainly adopts the basis that surperficial friction characteristics is set up in the charge character of microphysics in the physical chemistry and the macrophysics, according to differing materials singularity purposes performance in the macromolecular material, carried out comprehensive selection institute compositing formula composite shape matl and processed again.The present invention particularly has stronger grease proofing, skidproof effect than general rubber except strengthening its skidproof effect in general road surface walking when normal contact greasy dirt or smooth surface work walking.

Embodiment

The invention will be further described below in conjunction with embodiment: the percentage ratio among the following embodiment is mass percent.

The present invention adopts existing preparation technology, adopt following raw material to make sole material, each raw material is calculated by mass percentage: paracril N-41 33%, brominated butyl rubber BIIR-2255 8.3%; styrene butadiene rubber sbr 1,778 5.5%; polyvinyl chloride 8.3%; dibutyl ester 11%; white carbon black 22%; on-slip agent ceramics powder 2.2%; polyvinyl acetal modified phenolic resins 0.8%; phenol antioxidant BHT 0.7%; antifogging agent paraffin 0.6%; vulcanizing agent SULPHUR POWDER 1.1%; thiuram type accelerator DM 1.1%; promoting agent zinc oxide 3.2%; white smoke active agent polyvinyl alcohol PEG4000 2.2%.

Tested at the enterprising whereabouts sliding/friction of smooth surface ceramic tile coefficient by the sole that above-mentioned raw materials makes, the result is as follows:

Under the dry type situation: 1.1;

Under the wet type situation: 0.7;

Under the oil formula situation: 0.35;

Under the wet oil formula situation: 0.45;

The oil resistant experiment: soaked 22 hours in 50 ℃ octane-iso oil, its cubical expansivity is less than 12%.

The more common testing method standard of internationalization is adopted in anti-skidding experiment.

Anti-skidding test: adopt JAMES on-slip tester, the coefficient of friction on testing rubber piece and smooth ceramic tile surface is pressed the test of ASTM-F489 international standard.

Oil resistant test: adopt the EN-345 international standard to test.
