Problems solved by technology

However, rubber products may be difficult to return to their original shape after being subjected to long-term force, which is very unfavorable to the processing and application of rubber, and will limit the use and service life of rubber, so it also needs to be fully improved.

Abstract

The invention relates to a foamed rubber and a preparation method thereof. The foamed rubber comprises the following components in parts by weight: 1.0-7.0 parts of NBR rubber; 10.0 to 20.0 parts of EPDM rubber; 1.0 to 7.0 parts of SBR rubber; 0.1 to 1.0 part of a saturated higher fatty acid; 2.0 to 17.0 parts of carbon powder; 4.0 to 10.0 parts of OBSH foaming agent; and 0.5 to 4.0 parts of a peroxide. The foamed rubber disclosed by the invention has the advantages of appropriate resistivity, excellent ozone resistance, high recovery rate and good resilience. In addition, the preparation method of the foamed rubber is simple in process and easy to implement, and large-scale production can be achieved.

Description

technical field [0001] The invention relates to the field of macromolecules, in particular to a foamed rubber and a preparation method thereof. The foamed rubber has suitable resistivity, excellent ozone resistance and high recovery rate. Background technique [0002] In the operation of an image forming device (such as an electrostatic copier, laser printer, etc.) using the electrostatic copying method, the photosensitive body (such as a toner cartridge) with photoconductivity is first charged to make the surface have a uniform charge, and then accept Exposure forms an electrostatic latent image corresponding to the original image, and then the electrostatic latent image selectively absorbs toner at corresponding positions by electrostatic adsorption to form a toner image (development), and then the toner image is transferred to the copy medium (copy paper) and fix to complete the copying process. [0003] In the above-mentioned transfer process, in order to transfer the a...
