Abstract
The invention belongs to the technical field of polyurethane rubber rollers, and particularly relates to a permanent antistatic natural-color polyurethane rubber roller, wherein the rubber is preparedfrom the following raw materials by weight: 2-5 parts of a wear-resistant agent, 5-10 parts of an antistatic agent, 5-10 parts of glycerol, 5-20 parts of lithiumnitrate, 10-20 parts of lithiumoxalate, 5-10 parts of ethanol, 5-15 parts of butanediol, 5-10 parts of lithiumformate and 5-15 parts of diaminodiphenyl methane. The production method of the permanent antistatic natural-color polyurethane rubber roller comprises: adding glycerol into polyethylene glycol, heating to a temperature of 130-140 DEG C, dehydrating for 1.5 h under vacuum, heating to a temperature of 130-140 DEG C, dehydrating under vacuum, repeating the steps three times, and carrying out other steps after the temperature is reduced to 50-60 DEG C. According to the invention, the reactive antistatic agent is prepared by compounding the polyethylene glycol and the organic lithium salt, the polyurethane synthesized by the reactive antistatic agent is essentially an ionic electrolyte, and the polyurethane rubber roller prepared from the reactive antistatic agent has non-permanent antistatic property, cannot change the primary color of polyurethane, and can be used for preparing a transparent rubber roller.
Description
technical field [0001] The invention belongs to the technical field of polyurethane rubber rollers, and in particular relates to a permanent antistatic natural color polyurethane rubber roller. Background technique [0002] Polyurethane rubber is a kind of rubber with excellent tensile strength, elasticity and elongation at break. It is often used to prepare special rubber rollers and wear-resistant products used in various papermaking and smelting industries. [0003] The existing method of anti-static polyurethane rubber rollers is to add conductive particles such as carbon blackmetal oxides, but it will make the rubber rollers have a specific color; another method is to add surfactant antistatic agents, but this type of antistatic The antistatic agent has poor effect in low humidity environment, and the antistatic is easy to precipitate and fall off, resulting in poor antistatic effect or no antistatic effect at the end of the service life of the rubber roller.
