[0027] A preparation method of the antistatic rubber core-filled rubber shoes compound made of phosphogypsum whiskers, comprising:

[0028] (1) Weighing: get each component by weight parts;

[0029] (2) Rubber mixing: masticate 2# standard rubber on an open rubber mixing machine at a temperature of 20°C-50°C until the Vickers plasticity is 0.55-0.60, add sulfur, vulcanization accelerator, nano-zinc oxide, hard Fatty acid, phosphogypsum whiskers, salicylic acid, high wear-resistant carbon black, conductive carbon black, engine oil and dibutyl phthalate; then the rubber is kneaded evenly and the air bubbles are removed to make a thickness of 1.2 to 1.4 mm film, naturally cooled to room temperature;

[0030] (3) Vulcanization: cut the smelted film according to the shape of the shoe sole, put it in a vulcanization steam tank for 30 minutes to vulcanize, and then get the antistatic rubber core-filled rubber shoe compound made of phosphogypsum whiskers.

[0031] Paste the antistat...

Embodiment 1

[0042] Calculated in parts by weight, including 100 parts of standard glue, 2.5 parts of sulfur, 1.9 parts of vulcanization accelerator, 8 parts of nano zinc oxide, 13.5 parts of stearic acid, 80 parts of phosphogypsum whiskers, 0.5 parts of salicylic acid, 20 parts of high Wear-resistant carbon black, 25 parts of conductive carbon black, 15 parts of engine oil and 10 parts of dibutyl phthalate.

[0043] The phosphogypsum whiskers are mixed with a silane coupling agent at a ratio of 95:5, added to a high-speed blender for modification, and blended at a temperature of 120° C. for 20 minutes to be taken out.

[0044] The standard glue is 2# standard glue.

[0045] Described engine oil is 46# engine oil.

[0046] The vulcanization accelerator is that every 1.9 parts of the vulcanization accelerator is composed of 0.7 parts of accelerator M and 1.2 parts of accelerator DM.

[0047] The invention relates to a method for preparing antistatic rubber core-filling rubber shoes made o...

Abstract

The invention discloses an antistatic rubber core-filling rubber shoe rubber material prepared from phosphorus gypsum whiskers and a preparation method. The antistatic rubber core-filling rubber shoerubber material is prepared from the following raw materials in parts by weight: 95 to 115 parts of standard rubber, 2 to 3 parts of sulfur, 1.7 to 2 parts of vulcanization accelerant, 7 to 9 parts ofnano zinc oxide, 11 to 15 parts of stearic acid, 80 to 110 parts of phosphorus gypsum whiskers, 0.4 to 0.6 part of salicylic acid, 18 to 22 parts of high-wear-resistant carbon black, 20 to 25 parts of conducting carbon black, 13 to 18 parts of engine oil and 8 to 12 parts of dibutyl phthalate. The preparation method comprises the following steps: plasticating the number-2 standard rubber in an open-type rubber mixing mill at the temperature of 20 to 50 DEG C until wechsler plasticity is 0.55 to 0.60, adding other formulas such as sulfur and vulcanization accelerator; then uniformly turning and mixing the rubber material, eliminating bubbles, forming a rubber sheet, and naturally cooling the rubber sheet to the room temperature; and vulcanizing, thus obtaining the antistatic rubber core-filling rubber shoe rubber material. By adopting the antistatic rubber core-filling rubber shoe rubber material, the technical problems that the rubber core-fill rubber material is easy to generate aggregates or condensate and the dispersion effect is poor can be solved.

Description

technical field [0001] The invention relates to the field of rubber processing, in particular to an antistatic rubber core-filled rubber shoe compound made of phosphogypsum whiskers and a preparation method. Background technique [0002] The rubber core compound of rubber shoes is mainly used for disulfide rubber shoes. Its function is to fill the groove formed by the sponge of the disulfide shoe and the upper foot, and to bond the outsole of the rubber shoe with the anti-static core and the sponge through vulcanization conditions. A whole. The antistatic rubber core compound of conventional disulfide shoes is prepared with clay, because clay is easy to produce aggregates or agglomerates in rubber, which makes the dispersion effect poor and affects the antistatic effect and reinforcement of rubber core compound role, and clay is mainly concentrated in Guangdong, Shaanxi, Fujian, Jiangxi, Hunan and Jiangsu, accounting for 84.55% of the country's total reserves, while clay re...
