Embodiment A

[0028] Synthesis of antistatic agent ASA-1

[0029] (1) In a 500mL dry three-necked flask, add 40g (0.10mol) polyethylene glycol (PEG, molecular weight 400), 64.5g (0.7mol) of epichlorohydrin, 50% (mass fraction) sodium hydroxide aqueous solution 24g (0.3mol), catalyst tetrabutylammonium bromide 1.60g (0.005mol), dichloromethane 40ml warmed to 50 ℃ reflux reaction, then vigorously stirred for 4h, cooled to room temperature, suction filtration. Add anhydrous sodium sulfate to dry, and filter with suction. The filtrate was distilled to remove the solvent dichloromethane and unreacted epichlorohydrin to obtain a colorless viscous crude product. The above products were directly used in the next reaction without further purification.

[0030] (2) In a 250 mL dry three-necked flask, add all the crude products synthesized above, 19.2 g (0.2 mol) of trimethylamine hydrochloride, and 30 mL of ethanol, and stir at 30° C. for 3 h. The solvent was distilled off to get the crude product...

Embodiment B

[0032] Synthesis of antistatic agent ASA-2

[0033] (1) In a 500mL dry three-necked flask, add 100g (0.10mol) polyethylene glycol (PEG, molecular weight 1000), 64.5g (0.7mol) of epichlorohydrin, 50% (mass fraction) sodium hydroxide aqueous solution 24g (0.3mol), catalyst tetrabutylammonium bromide 1.60g (0.005mol), dichloromethane 40ml warmed to 50 ℃ reflux reaction, then vigorously stirred for 4h, cooled to room temperature, suction filtration. Add anhydrous sodium sulfate to dry, and filter with suction. The filtrate was distilled to remove the solvent dichloromethane and unreacted epichlorohydrin to obtain a colorless viscous crude product. The above products were directly used in the next reaction without further purification.

[0034] (2) In a 250 mL dry three-necked flask, add all the crude products synthesized above, 19.2 g (0.2 mol) of trimethylamine hydrochloride, and 30 mL of ethanol, and stir at 30° C. for 3 h. The solvent was distilled off to obtain a crude prod...

Abstract

The invention provides a reaction type antistatic agent. The antistatic agent is generated by reacting an intermediate which is synthesized under the alkaline condition based on polyethylene glycol and epoxy halopropane as raw materials with trialkylamine haloid, wherein the molecular weight of polyethylene glycol is 400-2,000. The invention also provides a preparation method of the reaction type antistatic agent, which comprises the following steps of: (1) synthesizing the intermediate at 40-60 DEG C under the alkaline condition by taking polyethylene glycol and epoxy halopropane as the raw materials; and (2) reacting the intermediate with trialkylamine haloid in an alcohol solvent at 20-40 DEG C to obtain the reaction type antistatic agent. The invention also provides an antistatic polyurethane material which is prepared by mixing and pouring a raw material A and a raw material B, wherein the raw material A comprises polyhydric alcohol, a catalyst, a foaming agent, a chain extender and the reaction type antistatic agent; and the raw material B is isocyanate.

Description

technical field [0001] The invention relates to a polymer material and a preparation method thereof, in particular to a polyurethane material and a preparation method thereof. The polyurethane material is mainly used for making shoe soles. Background technique [0002] Electrostatic charges can build up on or readily build up on electrical insulators or preparations insulated by electrical insulators. There are many hazards of static electricity, and its first hazard comes from the interaction of charged bodies. When the aircraft body rubs against air, water vapor, dust and other particles, the aircraft will be electrified. If no measures are taken, it will seriously interfere with the normal operation of the aircraft radio equipment, which may lead to aircraft accidents; The static electricity will make the paper stick together, it is difficult to separate, and it will bring trouble to the printing; in the pharmaceutical factory, because the static electricity attracts dus...
