Problems solved by technology

Although the poly(dimethylbutylammonium methacrylate bromide-styrene) amphiphilic copolymer 89 reported in Plastics (2011,40(3):76-79) can reduce the surface resistivity of ABS resin to 10 The level of -10Ω, but it is greatly affected by the ambient humidity, and it still has a large surface resistivity when the humidity is relatively low
And the surface resistivity of the sample increases by 2-3 orders of magnitude after being boiled in water for 2.5 hours, and the heat resistance and durability are relatively poor

Abstract

The invention discloses a cationic / nonionic composite polymer antistatic-agent. The cationic / nonionic composite polymer antistatic-agent is synthetized from lauric diethanolamide, dimethylethanolamine and polycaprolactone by the method of free radical polymerization. In the antistatic agent, the lauric diethanolamide is a cationic surface active agent with high charge density, the dimethylethanolamine is a nonionic antistatic agent, and the synergistic effect of the two gives a good antistatic performance to ABS resin; the polycaprolactone provides good compatibility of the antistatic agentand the ABS resin. The unique molecular structure of the antistatic agent makes the ABS resin has a durable antistatic performance, and the disadvantage that general antistatic agents have poor durability is overcome.

Description

technical field [0001] The invention relates to a cationic / nonionic composite polymer antistatic agent and a preparation method thereof, in particular to a cationic / nonionic composite polymer antistatic agent suitable for ABS resin and a preparation method thereof. Background technique [0002] ABS resin is a widely used engineering plastic, but its own good insulation, high surface resistivity, easy to generate static electricity during use, which limits its application in some occasions. For example, in the use of mining electrical appliances, if too much static charge is generated, it will cause surface discharge and cause fire and explosion. [0003] Cationic surfactants such as quaternary ammonium salts have high antistatic effects, so they are widely used as antistatic agents for polymers. However, they have disadvantages such as poor compatibility with polymers, rapid oozing out of the surface to produce stickiness, and poor heat resistance. Poor compatibility betwe...
