Problems solved by technology

These methods are nothing more than changing the external environment or changing the properties of the polymer, and the processing cost is high.
Among the antistatic agents currently used, the antistatic agent is mainly a surfactant, and the cationic antistatic agent has excellent antistatic performance, but has poor heat resistance and is harmful to the skin; anionic heat resistance and antistatic effects are both It is better, but it has poor compatibility with resin and affects the transparency of the product; the characteristic of zwitterionic antistatic agent is that it can be used in conjunction with both cationic and anionic antistatic agents, and the antistatic effect is similar to Cationic type, but its heat resistance is not as good as that of anionic type; non-ionic antistatic agent has good compatibility and heat resistance, has no adverse effect on the physical properties of the product, and the dosage is relatively large

preparation example Construction

[0031] In one embodiment, a kind of preparation method of antistatic agent with flame retardant property, comprises the steps:

[0032] Under normal pressure, fatty amine and ethylene oxide are used as raw materials and hydrochloric acid is used as catalyst to synthesize ethoxylated fatty amine; the reaction formula is as follows:

[0033] RNH 2 +2C 2 h 4 O→RN(CH 2 CH 2Oh) 2 ;

[0034] RN(CH 2 CH 2 Oh) 2 +(m+n-2)C 2 h 4 O→RN(CH 2 CH 2 O) m H(CH 2 CH 2 O) n H; among them, CH 2 CH 2 The addition number n=2 of the O group, m is the polymerization addition number, which is naturally generated;

[0035] The antistatic agent with flame retardant properties is obtained by borate reaction of ethoxylated fatty amine and boric acid, and the reaction formula is as follows:

[0036] 2RN (CH 2 CH 2 O) m H(CH 2 CH 2 O) n H+B(OH) 3 →RN(CH 2 CH 2 O) m (CH 2 CH 2 O) n BRN (CH 2 CH 2 O) m (CH 2 CH 2 O) n H+3H 2 O.

Embodiment

[0086] 1. Under normal pressure, use dodecylamine and ethylene oxide as raw materials and hydrochloric acid as a catalyst to synthesize ethoxylated dodecyl / octadecylamine. Specific steps: (1) Add 185g of dodecylamine and excess hydrochloric acid (catalyst) into a three-necked flask, turn on the magnetic heating stirrer to heat, and at the same time, pass in nitrogen to purge the device for about 30 minutes, and when the temperature rises to 100 At ℃, turn off the nitrogen gas, then slowly introduce ethylene oxide gas, and adjust the flow rate so that the flow rate is 14ml / min. When the temperature rises to about 120°C, keep the temperature basically unchanged. After the reaction lasts for 6 hours, stop feeding ethylene oxide gas, let the reaction continue for 30 minutes, and then the reaction system cools down naturally; (2) When the temperature drops to about 80°C , Nitrogen gas was passed into and purged for 20 minutes to remove the remaining ethylene oxide gas in the reacto...

Abstract

The invention provides an antistatic agent with flame retarding performance, as well as a preparation method and application thereof. The preparation method comprises the following steps: synthesizingethoxylated fatty amine by using fatty amine and ethylene oxide as raw materials and hydrochloric acid as catalyst at normal temperature; performing boric acid esterification on the ethoxylated fattyamine with boric acid to obtain the antistatic agent with flame retarding performance. The antistatic agent with flame retarding performance, prepared by the method, has a long polyoxyethylene unit,longer conductive unit, reinforced hydrophilcity and relatively good antistatic performance. The antistatic agent has small dosage, the antistatic requirement can be met when the addition is 1.5 percent of mass of the whole polymer material, and the dosage of the antistatic agent can be reduced on the premise of keeping relatively good antistatic performance, so that the processing cost can be reduced. The antistatic agent has good antistatic performance and long antistatic duration.

Description

technical field [0001] The application relates to the field of material technology, in particular to an antistatic agent with flame retardant properties and its preparation method and application. Background technique [0002] Polypropylene (PP, Polypropylene) is a thermoplastic polymer obtained by polymerizing propylene monomers. Polypropylene has the advantages of high melting point, high strength, high heat resistance, high wear resistance and low creep. Polypropylene also has Good tensile strength, yield strength, rigidity, stress resistance and electrical insulation and other excellent properties, because of its excellent performance, rich raw materials and low price, polypropylene has become the fastest growing and most widely used in general resins one of the species. It is widely used in plastics, rubber and fibers according to its molecular structure. [0003] It can be understood that when two solids with different physical states come into contact with each othe...
