Draw through above-mentioned test, optimum formula and processing condition are following:
Optimum formula: 60 parts of tree elastomers, 10 parts of styrene-butadiene rubber(SBR), 30 parts of cis-1,4-polybutadiene rubbers, 2.0 parts of sulphur, 0.5 part of altax, 1.0 parts of accelerant CZs, 0.5 part of light magnesium oxide, 3 parts of stearic acid and 5 parts of nano zine oxides, 3 parts of solid coumarones, 17 parts of machinery oil, 55 parts of high wear-resistant carbon blacks.
Process control condition: sulfuration starting point 2 ' 50 "～3 ' 20 ", the broken-(down)rubber plasticity number 0.40～0.50 of tree elastomer.
Sulfuration system end operation scheme is: after adding the sole film in the mould in vulcanizing press; Matched moulds is pressurized to operating pressure 20MPa; The matched moulds time was kept 1 second, unclamp exhaust handle, make the filler mould drop to the end; So repetitive operation is 3 times; Matched moulds is pressurized to operating pressure 20MPa again, keeps operating pressure and homo(io)thermism sulfuration 3-8min, and curing cycle finishes; Rapping takes out rubber from mould.The exhaust number of times that requires simultaneously to add is no more than 1 time, and must accomplish continuously at the sulfuration matched moulds in earlier stage.
The product that obtains through the present invention is directly generated by the rubber components original position, and rubber body realizes the loss of gloss effect.
From optical angle, loss of gloss is claimed loss of gloss again, is meant after the gloss paint film forming that tarnish or paint film were glossy at that time after doing, the gloss phenomenon of fading in a short time, and its reason is that article surface is too coarse.
Corresponding with loss of gloss, to be product weaken the part of light in delustring, and the product surface glossiness is less than 16% the delustring that is.The body delustring of product comes from the optical heterogeneity of body, and this and material property have substantial connection, and wherein the factor of most critical is a refractive index difference between inner each microcell of goods.When light sees through product surface entering goods inside; The inner optical heterogeneity of goods makes light that repeatedly refraction take place, and refraction each time all can be followed scattering and cause light intensity loss, increases this volume scattering; The light that on incident direction, appears goods thus will weaken greatly, thereby form delustring.Black rubber does not produce the light transmission phenomenon; In order to reach body loss of gloss purpose, must guarantee that the reflective angle of light that shines on the rubber surface is little, require rubber article that light is had good diffuse-reflectance performance; Product surface has extremely strong scattering process to light, could realize the loss of gloss effect.
According to above-mentioned experimental data; Directly utilize its bulk material and surface treatment to realize the loss of gloss effect through the prepared loss of gloss type sole that obtains of the present invention; After this bulk material adopts matte surface to handle; Through suitable working method; Guarantee that sandblast forms splendid surfaceness, keep the surperficial loss of gloss of realizing vulcanized rubber for a long time.Technology of the present invention is simple; Need not reduce production cost, only need carry out a spot of simple frosted and handle at die surface to rubber overshoes spray extinction surface face oil; Significantly reduced working strength of workers, and sole surface loss of gloss effect can not change because of use.
