Embodiment Construction

[0018] A preparation method for wear-resistant and antistatic rubber soles, comprising the steps of:

[0019] (1) Mastication: Mix 70 parts of natural rubber and 0.1 part of peptizer DS-T-1 in a honey mixer at a temperature of 100°C for 7 minutes, and then make a roll on an open rubber mixer. Masticated rubber with Vickers plasticity of 0.45-0.55;

[0020] (2) Master mixing: Put 30 parts of solution-polymerized styrene-butadiene rubber, 10 parts of natural rubber, 4 parts of solid coumarone and 1 part of stearic acid into the honey mixer, and press at 100°C for 60 seconds, Put in 8 parts of conductive carbon black and 6 parts of rubber softening oil, and when the load pointer of the working ammeter of the honey mill rises to above 200A, put in 20 parts of high wear-resistant carbon black and 9 parts of engine oil, and press until the load of the working ammeter of the rubber mixer The pointer rises to above 200A, and after 5 minutes of pressing, the material is discharged to ...

Abstract

The invention discloses a preparation method of a wear-resistant and anti-static rubber soles. The preparation method comprises the steps of (1) plasticization, (2) master batching, (3) mixing, (4) thermal plasticization and molding, and (5) sole preparation. According to the preparation method, the simplicity is realized, the production process requirement is low and the production cost is low. A conductive rubber sole sizing material is good in anti-static performance, wet skid resistance coefficients reach 0.73 to 0.75, the rubber Akron wear volume of rubber soles is smaller than 0.4cm<3> / 1.61km, and the resistance is 0.1 to 1megohm. According to the method, static electricity carried by a human body can be removed in a flammable and combustible production place, so that fire and explosion can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a preparation method of a wear-resistant and antistatic rubber sole. Background technique [0002] At present, conductive rubber products are developing rapidly as functional rubber products, and their application range is becoming wider and wider. [0003] Conductive rubber is a composite conductive polymer material, and its conductive mechanism mainly includes macroscopic percolation theory (conductive pathway mechanism), microscopic quantum mechanical tunnel effect and microscopic quantum mechanical field emission effect. Conductive path mechanism, tunnel effect and field emission effect exist in conductive rubber at the same time, and one or two mechanisms may be dominant under different conditions. When the amount of conductive filler is above the critical amount, the conductive path is the main conduction mode, that is, the mechanism of the conductive path is do...
