Abstract

The invention relates to the technical field of electric imaging equipment, and particularly relates to an immersing material transferring roller. The immersing material transferring roller is prepared by soaking a transferring roller in an immersing solution, wherein the immersing solution comprises the following raw materials in parts by weight: 15-25 parts of an acrylate polymerized emulsion, 12-22 parts of a colorant, 1-2 parts of an impregnating agent, 0.1-0.3 part of a defoaming agent and 40-60 parts of water. The immersing solution adopts the raw materials with the weight ratio strictly controlled; when the transferring roller is soaked in the immersing solution, the prepared immersing material transferring roller is soft in sense of touch and excellent in conductivity; the immersing material transferring roller is prepared by soaking the transferring roller in the immersing solution, and is soft in sense of touch, excellent in conductivity, durable in washing and good in dry cleaning effect, the C hardness is 32.5+ / -17.5 degrees, and the resistance is less than 1*10<4> omegas.

Description

technical field [0001] The invention relates to the technical field of electro-imaging equipment, in particular to an impregnated material transfer roller. Background technique [0002] The transfer roller is the main component used in equipment such as printers or copiers. Its main function is to use its own material to have a certain degree of electrical conductivity. After external charging is applied to make itself have a certain amount of charge, it uses the principle of positive and negative charges. Adsorbs the toner attached to the surface of the photoreceptor to the surface of the paper. [0003] With the increasing requirements of users for transfer rollers, the demand for high-speed printing is increasing. To achieve high-speed printing performance, a transfer roller with softer and lower resistance is required. However, the commonly used rubber materials and foam materials are currently It is difficult for the transfer roller to achieve this performance. Conte...
