Embodiment 1
[0089] A compound antistatic agent, in parts by weight, comprises the following components: component A is 4 parts of a long-acting antistatic agent; component B is 6.2 parts of a water-absorbing antistatic synergist;
[0090] Among them, the B component includes the following components: 3.5 parts of polyacrylamide, 1.8 parts of phenolic resin, and 0.6 part of crosslinking agent.
[0091] Among them, the long-acting antistatic agent is polyetheramine, and the crosslinking agent is ferric trichloride hexahydrate.
[0092] The preparation method of above-mentioned compound antistatic agent is as follows:
[0093] S1. Mix the polyacrylamide, the phenolic resin and the cross-linking agent evenly to obtain a water-absorbing antistatic synergist;
[0094] S2. Mix the long-acting antistatic agent and the water-absorbing antistatic synergist to obtain a compound antistatic agent.
Embodiment 2
[0096] A compound antistatic agent, in parts by weight, comprises the following components: component A is 0.3 part of a long-acting antistatic agent; component B is 8.3 parts of a water-absorbing antistatic synergist;
[0097] Among them, the B component includes the following components: 3.5 parts of polyacrylamide, 1.8 parts of phenolic resin, and 0.6 part of crosslinking agent.
[0098] The difference from Example 1 is that the amounts of component A and component B are different.
[0099] The preparation method is the same as that in Example 1, and will not be repeated here.
Embodiment 3
[0101] A compound antistatic agent, in parts by weight, comprises the following components: component A is 5 parts of a long-acting antistatic agent; component B is 2.3 parts of a water-absorbing antistatic synergist;
[0102] Among them, the B component includes the following components: 3.5 parts of polyacrylamide, 1.8 parts of phenolic resin, and 0.6 part of crosslinking agent.
[0103] The difference from Example 1 is that the amounts of component A and component B are different.
[0104] The preparation method is the same as that in Example 1, and will not be repeated here.

Abstract
The invention discloses a compound antistatic agent, an antistatic polypropylene material and a preparation method and application thereof. The compound antistatic agent is prepared from the following components in parts by weight: 0.3 to 5 parts of a component A which is a long-acting antistatic agent and 2.3 to 8.3 parts of a component B which is a water-absorbing antistatic synergist, wherein the component B comprises the following components in parts by weight: 1-4 parts of polyacrylamide, 1-3 parts of phenolic resin and 0.2-0.8 part of a cross-linking agent. According to the compound antistatic agent disclosed by the invention, an excellent antistatic effect can be realized through the optimized synergistic effect of the long-acting antistatic agent and the water-absorbing antistatic synergist, the surface resistance is greatly reduced, and the stability and durability of the antistatic effect of a composite material are improved. The invention also discloses an antistatic polypropylene material which comprises the compound antistatic agent and a polypropylene material and has an excellent antistatic effect.
Description
technical field [0001] The invention belongs to the field of polymer materials, and particularly relates to a compound antistatic agent, an antistatic polypropylene material and a preparation method and application thereof. Background technique [0002] Polypropylene (PP) is a semi-crystalline polymer with excellent mechanical properties, heat resistance, chemical resistance and easy formability, and is widely used in industries such as automobiles, home appliances and construction. Polypropylene has strong electrical insulation due to its low molecular surface polarity and poor water absorption (surface resistivity is as high as 10 16 Ω·m), during the production and use process, static electricity will be generated and accumulated on the plastic surface due to friction, peeling or induction process, resulting in electrostatic hazards, such as dust collection, discharge, breakdown, and even burning or explosion. Static electricity will also prevent all the materials in the ...
