Abstract

The invention discloses a core-shell type silicon-containing synergistic flame retardant and a preparation method thereof, which is characterized in that 50ml of deionized water and 150ml of ethanol are added into a reaction kettle equipped with a stirring and reflux device, and after stirring evenly, 50g of Ammonium polyphosphate and 1g OP-10, heated to 45°C under stirring, added concentrated ammonia water to adjust the pH value to 9-11, then slowly added 5g organic silicon oxide compound dropwise at a speed of 3ml / min, stirred for 150min, and then The reaction kettle was lowered to room temperature, filtered, washed, and the filter cake was dried at 120°C and 30mmHg. The average particle size of the obtained product does not increase significantly, the free flow of particles is good, the shell is dense and uniform, the water property is greatly reduced, and the high temperature water resistance is significantly improved. It can be used as a polymer material such as polyolefin, polyurethane, rubber, and foam. Flame retardant, it can also be used for flame retardant of paper, wood, fabric, etc.

Description

technical field

[0001] The invention belongs to the technical field of flame retardants, and in particular relates to a core-shell silicon-containing synergistic flame retardant and a preparation method thereof. Background technique

[0002] As people pay more and more attention to environmental protection and personal health, the European Union issued the "Directive on the Prohibition of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" ("ROHS Directive"), which makes manufacturers of flame-retardant materials in various countries begin to use caution The attitude towards the application of brominated flame retardants in polymers has led to the emergence of non-halogenated flame retardants, especially phosphorus-based flame retardants, which are constantly moving from the laboratory to the market. On pages 13-20 and 48-53 of the book "Basics and Applications of Halogen-Free Flame-Retardant Polymers" (Wang Jianqi, Science Press, 2005.6), it is p...
