Problems solved by technology

Adding conductive carbon black will obviously change the color of the product, and usually the amount added is relatively large, which is not suitable for products with light color and high requirements for cleaning and sanitation; for ionic surfactants, it is necessary to choose a surface with moderate compatibility with the rubber matrix The type of active agent, when the compatibility between the surfactant and rubber is too good, it will restrict its ability to migrate and diffuse in the rubber, thereby reducing the electrical conductivity of the system; otherwise, the compatibility of the surfactant is too poor, and the surfactant will migrate to the surface of the rubber product The speed is too fast so that it is difficult to obtain lasting antistatic performance; and the compounding of metal powder and rubber is easy to affect the flexibility and elasticity of rubber, and the cost is high, so it is rarely used in practical applications.

Abstract

The invention relates to the field of antistatic agents and discloses a long-acting, washable, low-temperature-resistant, colorless and transparent liquid antistatic agent and a preparation method ofthe long-acting, washable, low-temperature-resistant, colorless and transparent liquid antistatic agent. The antistatic agent comprises 20-55% of polyoxyethylene type nonionic surfactant, 5-10% of polyester polyol, 5-15% of ionic compound, 30-45% of dispersing agent and 5-10% of functional auxiliaries. The preparation method is simple in process and equipment and easy to operate, and the preparedantistatic agent is colorless and transparent, excellent in low temperature resistance, good in compatibility with rubber, low in use amount, capable of allowing a product to have a lasting antistatic effect, good in washability, especially suitable for a rubber system and widely applicable to the static resistance of products such as oil-resistant rubber pipes, conveying bels, sealing products and printing and dyeing products.

Description

technical field [0001] The invention relates to the field of antistatic agents, in particular to a liquid antistatic agent for long-acting washable and low temperature resistant colorless transparent rubber and plastic and a preparation method thereof. Background technique [0002] Rubber and plastics are electrical insulating materials. During use, charges are easy to accumulate to generate static electricity accumulation, which in turn causes serious accidents such as vacuuming, electric shocks, and even explosions caused by electric sparks. Adding antistatic agents to polymer materials can effectively prevent the accumulation of static electricity in rubber and plastic materials, which is a practical, simple and effective method. [0003] At present, the main method to improve rubber antistatic or conductivity includes adding conductive carbon black (Rubber Industry Dictionary Compilation Group. Rubber Industry Dictionary Antistatic Rubber [M]. Beijing: Chemical Industry ...
