Abstract
The invention discloses a method for modifying an inorganic flame retardant composite. The method comprises the following steps of: adding montmorillonite and Mg(OH)2 in deionized water at a temperature of 65-75 DEG C, and stirring the montmorillonite and the Mg(OH)2 evenly to obtain montmorillonite and Mg(OH)2 dissolving pulp; adding a cation modifier in the montmorillonite and Mg(OH)2 dissolving pulp, stirring the cation modifier and the dissolving pulp for 2-3 hours to obtain a mixture after modifying the montmorillonite and Mg(OH)2; drying the mixture in an oven for 20-35 hours at a set temperature of 70-80 DEG C; and performing ball milling on the dried mixture in a ball mill for 4-8 hours, drying the mixture in the oven, and performing ball milling and sieving on the mixture to obtain the inorganic flame retardant composite. Through chemical modification, the inorganic flame retardant composite is low in use amount, good in compatibility and high in flame-retardant efficiency, and can meet the performance requirements of different products.
Description
Technical field
The present invention relates to a kind of method of modifying of inorganic composite flame retardants, specifically a kind of to polynite and Mg (OH)
2The method that the composite flame-retardant agent of forming carries out modification.
Background technology
Polynite and Mg (OH)
2All be inorganic combustion inhibitor, flame retardant effect is better, and wherein polynite has bigger specific surface area (750 m
2/ g), and Mg (OH)
2Less (57.34 m of specific area
2/ g), the two is as the filled fire retardant, and the size of its specific area and the performance of goods have confidential relation, so select both to do composite flame-retardant agent, make it can satisfy the requirement of different product propertiess.
But the two all has the surface hydrophilic oleophobic; Relatively poor with organic consistency; Be unfavorable for its application in organic materials, in order to change this now so it is carried out modification handle, make its satisfy current society to low toxicity of fire retardant, press down cigarette, anti-molten, environmental protection, demand efficiently.
Summary of the invention
The method of modifying that the purpose of this invention is to provide a kind of inorganic composite flame retardants, this method is carried out chemical modification to inorganic composite flame retardants, makes that its consumption is low, consistency good, flame retarding efficiency is high, and can satisfy the performance requriements of different goods.
The objective of the invention is to realize through following technical scheme:
A kind of method of modifying of inorganic composite flame retardants is characterized in that this method comprises the steps:
1) will cover holder soil and Mg (OH)
2Join in 65 ℃ ~ 75 ℃ the deionized water, stir, obtain polynite and Mg (OH)
2Dissolve slurry; Wherein, polynite and Mg (OH)
2Part by weight be 1:0.05 ~ 1:2.4; Polynite and Mg (OH)
2Total mass is 1:0.06 ~ 1:2.2 with the ratio of water;
2) to above-mentioned polynite and Mg (OH)
2Add cation modifier again in the molten slurry, stir 2-3 h, make polynite and Mg (OH)
2Mixture after the modification; Polynite and Mg (OH)
2The quality of molten slurry with the ratio of cation modifier quality is: 50:1 ~ 60:1;
3) mixture is put into baking oven, design temperature is 70-80 ℃, dry 20 ~ 35 h;
4) dried mixture is put into ball crusher, ball milling 4 ~ 8 h put it into drying in the baking oven again, and ball milling sieves then; Promptly make inorganic composite flame retardants.
Among the present invention, said cation modifier is one or more mixtures in ZX-I (PA-Na), octadecyl methyl ammonia chloride, the pure ether phosphate.The sieve aperture that uses when sieving is the 200-400 order.
