Abstract
The present invention is a kind of quaternary ammonium salt cationic surfactant, with alkyl chloride and diethanolamine and methyl-sulfate (or ethyl sulfate) synthesizing polyvinyl chloride method for synthesis of anti-static agent, is mainly used in polyvinyl chloride plastic material products static inhibitor.It is simple that the present invention has technology, and antistatic effect is good, heatproof, advantage such as price is low, and the user is easy to use.
Description
The invention belongs to the synthesizing polyvinyl chloride static inhibitor, improve a kind of method of anti-static agent for PVC performance.
Existing static inhibitor kind is few, and with the static inhibitor of polrvinyl chloride product just still less, all adopts the operational path different with the present invention to synthesize, the not heatproof that its performance has, antistatic effect is good, or heatproof, antistatic effect is bad, and cost is high and influence quality product and promote the use of.
The objective of the invention is to overcome above-mentioned deficiency, providing a kind of can enhance product performance, the synthetic method of the anti-static agent for PVC that reduces cost.
Task of the present invention is following finishing:
At first RCl with
Reflux under alcohol catalysis agent effect, reacting generating compound
, then
With (CH

5)
2SO
4] the reaction generation
Anti-static agent for PVC.
Its reaction formula is
R is C in the formula
10-16Alkyl.
The synthetic method of anti-static agent for PVC of the present invention is compared advantages such as having technology is simple, antistatic effect good, heatproof, cost is low, the user is easy to use with other.
Embodiment:
With RCl and
Weighing in 1: 1 in molar ratio is good, adds band respectively and stirs and has in the reaction vessel of reflux, adds the catalyzer alcohol solvent, consumption be RCl and
The 5-10% of gross weight, heating is 160-175 ℃ under stirring and refluxing, and this thermotonus 6 hours, after reaction finished, reaction solution was cooled to 110 ℃ of weighing (CH
