Abstract

The invention discloses a high-toughness rubber material with mildew-proof and antibacterial properties and a preparation method thereof. The high-toughness rubber material is prepared from the following raw materials in parts by weight: 100 to 200 parts of natural rubber, 20 to 30 parts of p-tert-butylphenol formaldehyde resin, 40 to 50 parts of gel, 30 to 60 parts of stearic acid, 0.1 to 0.3 part of accelerant DM, 10 to 30 parts of paraffin, 3 to 10 parts of light calcium carbonate, 0.5 to 1 part of mildew-proof and antibacterial agent and 4 to 10 parts of industrial sulfur. The preparation method comprises the following steps: 1, weighing the raw materials in parts by weight; 2, mixing the natural rubber with p-tert-butylphenol formaldehyde resin, gel, stearic acid and an accelerant DM to obtain a first mixture; 3, mixing paraffin, light calcium carbonate and the mildew-proof antibacterial agent to obtain a second mixture, mixing the first mixture and the second mixture and adding industrial sulfur, then subjecting the mixture to thin passing for 3-5 times to obtain the high-toughness rubber material with the mildew-proof antibacterial performance.

Description

technical field [0001] The invention belongs to the technical field of rubber material preparation, and in particular relates to a high-toughness rubber material with mildew-proof and antibacterial properties and a preparation method thereof. Background technique [0002] As a renewable and recyclable material, rubber material is widely used because of its low cost and good performance. And because of its wide range of use and diverse use environments, it is often used in relatively harsh environments. In the process of use, often due to high environmental humidity or easy growth of bacteria in the environment, the rubber material will be eroded by mold and other bacteria and their secretions to cause biodegradation, greatly reducing its performance, and even causing serious damage. security issues. Contents of the invention [0003] In order to overcome the above-mentioned technical problems, the present invention provides a high-toughness rubber material with anti-mild...
