Embodiment 1

[0057] The present embodiment is a preparation method of a super flame retardant additive, comprising the following steps:

[0058] A1: Add 10 mmol of hexachlorocyclotriphosphazene, 65 mmol of p-hydroxybenzaldehyde, 100 mL of acetone and 13.5 g of potassium carbonate to a three-necked flask equipped with a stirrer, a thermometer and an airway, and introduce nitrogen protection at a temperature of 20 °C , stir for 15 minutes at a stirring rate of 300 r / min, then heat up to 70 °C while stirring, control the heating rate to 2 °C / min, and then continue to stir for 50 h. After the reaction, the reaction product was cooled to 5 °C, and then vacuumed Suction filtration, the filtrate was washed 3 times with sodium carbonate solution with a mass fraction of 10%, distilled water and n-hexane in turn, then recrystallized in ethyl acetate, and then placed in a vacuum drying box at a temperature of 70 ° C. Dry to constant weight to obtain Intermediate 1;

[0059] A2: Add 10 mmol of Interm...

Embodiment 2

[0064] The present embodiment is a preparation method of a super flame retardant additive, comprising the following steps:

[0065] A1: Add 10 mmol of hexachlorocyclotriphosphazene, 70 mmol of p-hydroxybenzaldehyde, 120 mL of acetone and 14.5 g of potassium carbonate to a three-necked flask equipped with a stirrer, a thermometer and an airway, and introduce nitrogen protection at a temperature of 30 °C , stir for 25 minutes at a stirring rate of 500 r / min, then heat up to 75 °C while stirring, control the heating rate to 3 °C / min, and then continue to stir the reaction for 70 h. After the reaction, the reaction product was cooled to 10 °C, and then vacuumed Suction filtration, the filtrate was washed 5 times with 15% sodium carbonate solution, distilled water and n-hexane in turn, then recrystallized in ethyl acetate, and then placed in a vacuum drying box, at a temperature of 75 ℃. Dry to constant weight to obtain Intermediate 1;

[0066]A2: Add 10 mmol of Intermediate 1, 70...

Embodiment 3

[0071] The present embodiment is a preparation method of high dispersibility carbon black, comprising the following steps:

[0072] B1: Add 10g of carbon black and 50mL of hydrogen peroxide solution with a mass fraction of 30% into a three-necked flask equipped with a stirrer and a thermometer, stir and react for 8h at a temperature of 78°C and a stirring rate of 300r / min, After the reaction is completed, the reaction product is cooled to room temperature, then washed with distilled water until neutral, and then placed in a vacuum drying oven, and dried to constant weight at a temperature of 60 ° C to obtain oxidatively modified carbon black;

[0073] B2: Add 10g of oxidatively modified carbon black and 120mL of toluene into a three-necked flask equipped with a stirrer, a thermometer, a reflux condenser and a gas guide, and stir for 30min at a temperature of 20°C and a stirring rate of 300r / min. After that, nitrogen protection was introduced, and 3.5 g of silane coupling agent...

Abstract

The invention relates to the field of color master batches, and aims to solve the problems that the compatibility of carbon black and ethylene-vinyl acetate copolymer in the existing carbon black colored ethylene-vinyl acetate copolymer color master batches is poor, and the prepared color master batches are poor in flame retardant property and easy to burn. In particular to a carbon black colored ethylene-vinyl acetate copolymer color master batch and a preparation method thereof, a carbon black coloring agent in the color master batch is high-dispersity carbon black, so that the compatibility between the carbon black and the ethylene-vinyl acetate copolymer color master batch is greatly improved, and the carbon black can be uniformly dispersed in the ethylene-vinyl acetate copolymer color master batch; the problems of non-uniform coloring and large color difference caused by agglomeration are avoided; the color master batch is endowed with good flame retardance by adding the super-flame-retardant additive, the probability of fire disasters is reduced, and the problems of economic loss and personnel safety are solved.

Description

technical field [0001] The invention relates to the field of color masterbatch, in particular to a carbon black colored ethylene-vinyl acetate copolymer color masterbatch and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people not only pay attention to the performance of various products in life, but also increasingly pursue their environmental protection and safety. Because plastic products have abundant raw material sources, low prices, non-toxic, easy molding and processing, high rigidity and toughness , good mechanical strength and other advantages, so now people's lives are full of all kinds of plastic products, and color masterbatch coloring is the most commonly used plastic coloring method today. [0003] Carbon black coloring ethylene-vinyl acetate copolymer masterbatch is mainly composed of carbon black colorant and ethylene-vinyl acetate copolymer. However, in the application process of carbon black...
