Description
Technical field
The present invention relates to footwear material technical field, particularly relate to a kind of synthesis Light rubber material for sole and preparation method thereof.
Background technology
The quality of a pair of leather shoes quality, wears whether comfortable not only with design, manufacture craft is relevant, also closely related with the selection of each component materials.Sole is the major parts of composition leather shoes, and it is with ground direct friction, and the weight of whole pressure when subject physical activity and shoes itself, thus should consider during selection it weight, surely fastness, thickness and folding, the performance such as wear-resisting; Consider the comfortableness that human consumer wears again simultaneously.The performance of sole each part material has comfortableness when wearing greatly to be affected.
The rubber-sole developed on the market at present has more and more thicker trend, and sole thickening will inevitably cause its weight to increase, in order to avoid the significantly increase of weight affects its comfortableness, this just requires that material for sole of shoe has less density, also will have that wearing and tearing are low, earth-grasping force strong, the characteristic of good springiness simultaneously.
Summary of the invention
The object of the invention is to for above problem, provide a kind of and have that density is low, wear resistance is strong, the synthesis Light rubber material for sole of good springiness and preparation method thereof.
In order to realize above object, the technical solution used in the present invention is: a kind of synthesis Light rubber material for sole, and this material is formed by the Raw material processing of following weight part: natural rubber 30-40 part, cis-1,4-polybutadiene rubber 30-35 part, polyisoprene rubber 30-35 part, ethylene octane copolymer POE 12-30 part, white carbon black 10-30 part, sulphur 1.5-2.5 part, vulcanization accelerator 2-3 part, white smoke active agent 6-8 part, processing aid 2.5-4 part.
Further, described vulcanization accelerator is zinc oxide.
Further, institute's white smoke active agent is polyoxyethylene glycol.
Further, described processing aid comprises stearic acid 1-1.5 part, rubber antifogging agent 0.5-1 part, rubber antioxidant 1-1.5 part.
Further, described rubber antioxidant is one or more in 2,2,4 trimethyl 1,2 dihydroquinoline polymer and N, N'-bis-(2-naphthyl) Ursol D.
For a preparation method for the synthesis Light rubber material of sole, it is characterized in that; The method comprises the following steps: first natural rubber is dropped into banburying 5-8 minute in Banbury mixer, and transferring to subsequently, roller begins to pratise obtains broken-(down)rubber in 5-8 minute, allows broken-(down)rubber naturally cooling carry out after more than 20 hours cutting glue; The broken-(down)rubber cut is dropped into Banbury mixer again and adds cis-1,4-polybutadiene rubber, polyisoprene rubber, white carbon black, vulcanization leveller banburying 4-5 minute make temperature rise to more than 90 degree successively, add ethylene octane copolymer POE, white smoke active agent, the mixing 6-8 minute of processing aid subsequently, transfer to slice on roller subsequently and cool more than 12 hours; Add sulphur after cooling and cut glue, finally dropping into and obtain finished product in mould sulfuration 5-7 minute under temperature is 145-160 DEG C and pressure is the processing condition of 12-20mpa.
Further, carry out again mixing after 20-24 hour in the cooling of material slice, concrete operations are as follows: get 40kg material and to drop in mill and to be transferred to 5-6 millimeter mixing 3 minutes, be adjusted to 3 millimeters subsequently and carry out plasticating 1-2 minute, finally add sulphur and in vulcanizer, carry out sulfuration to obtain finished product.
Further, add the coloring agent for painting when adding sulphur simultaneously.
The invention has the beneficial effects as follows: of the present invention a kind of be 0.852-0.880 g/cm for the POE density of material in its component of synthesis Light rubber material of sole
3, cis-1,4-polybutadiene rubber density 0.910 g/cm
3, and polyisoprene rubber density of material be 0.904 g/cm
3be the elastomeric material that density is lower, simultaneously POE also can carry out modification to material and makes material have good elasticity, the excellent in abrasion resistance of cis-1,4-polybutadiene rubber also can give material higher wear resistance, but due to the tensile strength of cis-1,4-polybutadiene rubber material lower, in formula, therefore add white carbon black improve the mechanical property of material as strengthening agent.
