Problems solved by technology

However, the durability of anti-static performance has always been a problem of long-term safety that cannot be ignored and urgently needs to be paid attention to.
[0003] At present, in the international and domestic industries, the ability to achieve 1*10E6~1*10E9 ohm static dissipation is often achieved by adding an antistatic agent to the formula, but because the antistatic agent is used as a surfactant and rubber raw materials or resins The raw materials are not completely compatible, and gradually precipitate out with time or environmental influences, resulting in an increase in resistance exceeding 1*10E9 ohms

Abstract

The invention relates to a long-acting anti-static rubber pad which comprises a static dissipation layer and / or a static conduction layer, and the static dissipation layer comprises the following rawmaterials in parts by weight: ECO epichlorohydrin rubber, nitrile rubber, a plasticizer, silicon dioxide, zinc oxide, an anti-aging agent, a softener, sulfur and a first accelerant; the static conductive layer is prepared from the following raw materials in parts by weight: rubber, light calcium carbonate, superconducting carbon black, high-wear-resistance carbon black, a plasticizer, white factice, a second accelerant, zinc oxide, sulfur, a defoaming agent and an anti-scorching agent. According to the invention, the ECO epichlorohydrin rubber with excellent electrostatic dissipation capability is used as a key raw material to realize durable antistatic performance, so that the problem that the antistatic performance is not durable due to the fact that an antistatic agent is easy to separate out under the influence of the environment is avoided. The volume resistance of the ECO epichlorohydrin rubber raw material can reach the grade of 106-108 ohms, and the ECO epichlorohydrin rubber raw material has a unique monomer structure and an ionic conduction mechanism and can be well compatible with various rubbers and resins.

Description

technical field [0001] The invention relates to the field of polymer chemical materials, in particular to a long-acting antistatic rubber mat. Background technique [0002] As a commonly used anti-static material in the industrial field, anti-static rubber mats have been widely used in the electrical and electronic industries, work surfaces / floors / shelves in the fields of flammable, explosive and hazardous chemicals. But the permanence problem of anti-static performance has always been a safety and long-term problem that cannot be ignored and needs to be paid attention to urgently. Especially in the production and operation of flammable and explosive hazardous chemicals, aerospace military industry, scientific research institutes and other experimental places, a high-quality and reliable new material with long-term effective anti-static is especially needed to ensure effective and safe protection of static electricity for a long time. [0003] At present, in the internation...
