Antistatic agent for dicyclopentadiene resin and preparation method thereof

Abstract

The invention discloses an antistatic agent for dicyclopentadiene resin and a preparation method thereof, and relates to the technical field of antistatic agents. The preparation method of the antistatic agent comprises the following steps: (1) mixing the 5-norbornenyl-2-methylene epoxypropyl ether and the lithium carbonate, and then, dehydrating through a nitrogen flow at 90-100 DEG C to obtain amixture A; (2) adding a DMC catalyst into the mixture A, introducing epoxybromopropane, stirring for 1-3 hours after the addition of the epoxybromopropane is finished to make the system fully react,and then, performing vacuumizing and cooling to obtain a polyether binary random block copolymer; and (3) adding N, N-dimethyl n-octylamine into the ethyl acetate solution containing the polyether binary random block copolymer to carry out quaternization reaction at 45-55 DEG C for 7-9 hours, and carrying out vacuum drying to obtain the antistatic agent. The color of the antistatic agent preparedby the method is adjustable, and the antistatic agent can provide lasting and effective antistatic property.

Description

technical field [0001] The invention relates to the technical field of antistatic agents, in particular to an antistatic agent for dicyclopentadiene resin and a preparation method thereof. Background technique [0002] In today's society, molded products have been widely used in daily life, but their high resistivity makes it easy to accumulate static electricity and cause harm. At present, fillers such as carbon black and graphite are often used as additive antistatic agents, which can reduce the resistivity of plastics, but also cause plastic products to turn black, limiting the application range of products. Dicyclopentadiene resin (DCPD) has the characteristics of low viscosity, fast reaction speed, rigid and tough polydicyclopentadiene (PDCPD) products after curing, and is often used in the preparation of automotive plastic parts. At present, there are few reports on antistatic agents for dicyclopentadiene resins. Although carbon black antistatic agents are effective, ...

Problems solved by technology

At present, there are few reports on antistatic agents for dicyclopentadiene resins. Although carbon black antistatic agents are effective, they make the product black; other commonly used antistatic agents have poor compatibility with dicyclopentadiene resins, or antistatic agents The functional groups contained in it will lead to the inactivation of its metal carbene curing agent, which will seriously reduce the mechanical properties of the product.
