Conductive rubber sheet can also use recycled rubber to reduce costs

We all know that the use of recycled rubber and nitrile rubber and then with the right amount of acetylene black can produce conductive or semi-conductive rubber products, conductive rubber products, if the mechanical properties require a higher, you need to increase the amount of nitrile rubber. Therefore, the conductive rubber sheet can also be produced by means of "recycled rubber + nitrile rubber + acetylene black". By adjusting the proportion of recycled rubber and nitrile rubber, the raw material cost can be reduced to the maximum under the premise of meeting the requirements of the conductive rubber sheet.

The main reason for the production of conductive plastic sheet is selected renewable plastic, nitrile rubber and acetylene black, because: First, the reclaimed rubber is scrap rubber products as the product of re-processing, so there are a lot of impurities, the body resistance Second, the conductivity of acetylene black is easy to control, the conductivity is not easy to be parked, the use of conditions, the impact of time; Third, the higher the general acrylonitrile content of the lower the resistivity of nitrile rubber, because nitrile Rubber is a typical polar rubber, in which the cyano group is a strong polar group, so the conductivity is good. Conductive rubber sheet from the performance to meet the basic needs of plastic conductivity; while the price of recycled rubber is nitrile rubber prices 1 / 4-1 / 3 or so, from the point of view the cost can also reduce production costs.

Reclaimed rubber production of conductive plastic plate, reclaimed rubber and nitrile rubber ratio of conductive plastic sheet has little effect, but if the amount of reclaimed rubber is too high but it will have an impact on the mechanical properties of conductive plastic sheet, so in Reduce costs at the same time according to the mechanical properties of conductive plastic sheet to determine the amount of demand for reclaimed rubber, less demanding for the mechanical properties of conductive plastic sheet can increase the amount of strict mechanical properties of conductive plastic sheet is required to increase the appropriate nitrile rubber The amount of 1: 1 for the common reclaimed rubber and nitrile rubber ratio.

Reclaimed rubber and nitrile rubber used in conjunction with the production of conductive plastic sheet, the general choice of sulfur as a vulcanizing agent at high temperature vulcanization, so easy to improve the conductivity of conductive plastic sheet, about 2 can be; vulcanization system accelerator can be accelerator DM As the main accelerator, an appropriate increase of CZ-assisted, because the two with vulcanization speed, high overall performance of conductive plastic sheet; carbon black acetylene black super wear-resistant carbon black has good electrical conductivity, so the use of acetylene carbon Black as a reinforcing filler, add appropriate amount of clay, light calcium; softener and more use of good compatibility with nitrile rubber dibutyl phthalate, cheap, difficult to penetrate; reclaimed rubber and nitrile rubber used in conjunction with the conductive Rubber sheet formulations also need a certain amount of stearic acid, antioxidants and other products with.

Reclaimed rubber and nitrile rubber used in conjunction with the production of conductive plastic sheet In order to reduce the cost of raw materials, you can use the higher fineness of the tire tread reclaimed rubber, the higher the fineness, the higher the gloss plastic sheet, the "Yan value" the better; Hongyun Imported fetal top ultra-fine reclaimed rubber is a good choice.
