Problems solved by technology

[0002] In the existing painting environment, the air will be mixed with more organic solvents, and there will be a small amount of liquid organic solvents on the ground. If the staff wear shoes with rubber outsoles in the painting workshop, they will be easily contaminated by organic solvents ( Such as acetone, methyl ethyl ketone, cyclohexanone, benzene, n-butanol, styrene, etc.) dissolve and adhere to the ground, causing damage to the shoe material and affecting the normal movement of the staff

Abstract

The invention relates to the technical field of soles and outsole, in particular to a silicon-free rubber outsole and a preparation method thereof. The silicon-free rubber outsole comprises the following raw materials in parts by weight: 75-100 parts of nitrile rubber, 10-20 parts of butadiene rubber, 5-15 parts of an active agent, 1-2 parts of an anti-aging agent, 5-8 parts of conductive carbon black, 25-45 parts of reinforcing carbon black, 1-3 parts of a dispersing agent, 1-3 parts of PEG-400, 5-10 parts of a plasticizer and 2-6 parts of an adhesive. The silicon-free rubber outsole can ensure the tensile strength, elongation at break, tear strength, wear resistance and aging resistance of a material, and does not contain silicon, so that the situation that the outsole is dissolved by an organic solvent and adhered to the ground in a paint spraying operation environment is avoided.

Description

technical field [0001] The invention relates to the technical field of soles and outsoles, in particular to a silicone-free outsole and a preparation method thereof. Background technique [0002] In the existing painting environment, the air will be mixed with more organic solvents, and there will be a small amount of liquid organic solvents on the ground. If the staff wear shoes with rubber outsoles in the painting workshop, they will be easily contaminated by organic solvents ( Such as acetone, methyl ethyl ketone, cyclohexanone, benzene, n-butanol, styrene, etc.) dissolve and adhere to the ground, causing damage to the shoe material and affecting the normal movement of the staff. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a non-silicone rubber outsole. It is found through research that the use of a silicon-free rubber outsole can avoid being dissolved by or...
