Abstract
The invention discloses a black bi-vulcanized rubber outsole for a mat high-modulus shoe, which comprises natural rubber, styrene-butadiene rubber, cis-1,4-polybutadiene rubber, sulfur, vulcanization accelerator, vulcanization activator, rubber softener and high-wear-resistant carbon black. The mat sole prepared by the invention realizes a matting effect by directly utilizing the own basic material and surface treatment. After being subjected to matting surface treatment, the basic material can definitely form excellent surface roughness by sand blasting through an appropriate operation method; and the basic material is kept for a long time to realize the surface matting of the vulcanized rubber. In the invention, the process is simple, and the spraying of matting oil on the surface of the rubber shoe is avoided; the production cost is lowered, and only a small amount of simple matting treatment on the surface of a mold is necessary; the labor intensity of workers is greatly reduced; and the surface matting effect of the sole can not be changed due to use.
Description
Technical field
The present invention relates to a kind of rubber soles complete processing, particularly a kind of loss of gloss type height is stretched footwear surely with at the bottom of black two sulphur and the preparation method.
Background technology
The rubber overshoes rubber components has two kinds of outward appearance development trends, a kind of is beautiful type product take high glossiness as representative, another kind is that color and luster is soft, the quiet elegance of outward appearance, give harmonious quiet style, make the loss of gloss type product that people feel safe, health is comfortable, this product has the special-effect of the sense organ vision that stimulates consumer, and becomes one of Major Epidemic trend of current product color.Loss of gloss type rubber overshoes product has become human consumer's new lover because of its soft, natural, graceful visual appearance.
At the bottom of claiming again rubber two sulphur at the bottom of two sulphur, refer to rubber at the bottom of the unit that mold hot sulfuration is processed into, because this sole is made rubber overshoes and also will once, is called the post cure rubber sole and be called for short " at the bottom of two sulphur by revulcanization after overmolding be fitted.
In general, the loss of gloss effect of rubber overshoes rubber components be realized, three kinds of approach can be adopted.The one, spray extinction surface face oil, but this mode kind technique is loaded down with trivial details, and not only cost is high, also can pollute Working environment because of the volatilization of delustring face Oil solvent, affects the staff healthy; The 2nd, the die surface of making rubber components to be carried out frosted process, this method is held time short, and poor effect, and labour intensity is large.The third is exactly directly to be generated by the rubber components original position, and realizes the loss of gloss effect by working method.But, also there is no a kind of loss of gloss type elastomeric material that is suitable at the bottom of rubber overshoes are produced black two sulphur at present.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of loss of gloss type height surely to stretch footwear with at the bottom of black two sulphur and the preparation method, product resulting according to it realized complete loss of gloss by rubber body, production method is simple, low production cost, labour intensity is low, resulting good product quality is to overcome the deficiencies in the prior art.
At the bottom of the present invention is achieved in that loss of gloss type height is stretched footwear use black two sulphur surely, calculate by weight, it comprises 50～65 parts of natural rubbers, 10～15 parts of styrene-butadiene rubber(SBR), 25～35 parts of cis-butadiene cements, 1.9～2.1 parts of sulphur, 1.2～2.0 parts of vulcanization accelerators, 6～10 parts of vulcanization levellers, 1.2～1.5 parts of anti-aging agent, 15～25 parts of Rubber Softener and 50～60 parts of high wear-resistant carbon blacks.
Preferred scheme is, calculate by weight, it comprises 60 parts of natural rubbers, 10 parts of styrene-butadiene rubber(SBR), 30 parts of cis-1,4-polybutadiene rubbers, 2.0 parts of sulphur, 1.5 parts of vulcanization accelerators, 8.5 parts of vulcanization levellers, 1.4 parts of anti-aging agent, 20 parts of Rubber Softener and 55 parts of high wear-resistant carbon blacks.
Also comprise 0.1～0.4 part of Whitfield's ointment and 1.0～1.5 parts of releasing agent 935P.
Every 1.5 parts of vulcanization accelerators are comprised of 0.5 part of altax and 1.0 parts of accelerant CZs.

Table 5
For preventing that vulcanized rubber from producing the glue dirt and causing patterned surface shinny, require with the mould sandblast once every day.To guarantee loss of gloss effect and level.
Conclusion (of pressure testing):
Draw by above-mentioned test, optimum formula and processing condition are as follows:
Optimum formula: 60 parts of natural rubbers, 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 natural rubber.
Vulcanizing the end processed operation scheme is: after adding the sole film in the mould in the 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, repeat operation 3 times, matched moulds is pressurized to operating pressure 20MPa again, maintenance work 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 at the sulfuration matched moulds in earlier stage, complete continuously.
The product that obtains by 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 claims again loss of gloss, refers to after the gloss paint film forming that tarnish or paint film are 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 refractive index difference between inner each microcell of goods.When light enters goods inside through product surface, the optical heterogeneity of goods inside makes light that repeatedly refraction occur, and refraction each time all can be followed scattering and cause light intensity loss, increases this volume scattering, the light that appears thus goods on incident direction 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 light reflecting angle that shines on rubber surface is little, require rubber article to light, good diffuse-reflectance performance to be arranged, 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 by the preparation-obtained loss of gloss type of the present invention sole, after this bulk material adopts matte surface to process, by suitable working method, guarantee that sandblast forms splendid surfaceness, keep the surperficial loss of gloss of realizing for a long time vulcanized rubber.Technique of the present invention is simple, do not need rubber overshoes spray extinction surface face oil has been reduced production cost, only need to carry out a small amount of simple frosted at die surface and process, greatly reduced workman's labour intensity, and sole surface loss of gloss effect can not change because of use.
