Abstract

The invention discloses a surface modification method of antimonous oxide special for flame-retardant masterbatch, and belongs to the field of preparation of active antimonous oxide. The preparation method comprises the following steps: using absolute ethyl alcohol as a solvent, preparing a solution by taking white graphite powder, chromium oxide powder, hexadecyl trimethyl ammonium chloride, ethylene dioleoyl amide and palmitol as solutes, adding antimony trioxide powder into an efficient ball mill for 5-8 minutes, adding the solution, filtering after ball milling, drying in a vacuum drying oven, and crushing and grading again to obtain the modified antimony trioxide. Data of embodiments 1-3 and contrast 5 show that the oxygen index of a sample is increased by at least 28.6%, and the smoke density grade is reduced by at least 25%. The flame-retardant synergistic effect of the modified antimony trioxide is improved, so that the use amount of the antimony trioxide in the flame-retardantfield can be reduced, and resources are saved.

Description

【Technical field】 [0001] The invention belongs to the field of preparation of active antimony trioxide, and in particular relates to a method for surface modification of antimony trioxide specially used for flame-retardant masterbatches. 【Background technique】 [0002] With the advancement of science and technology and the improvement of people's living standards, polymer materials, especially synthetic polymers: such as plastics and rubber, are becoming more and more important in people's lives, and their applications are showing a growing trend year by year. However, most organic polymer materials have different degrees of flammability in the air. In order to realize their applications in many industries such as military, aerospace, transportation, electric power and civil use, their flame retardant modification has become a new topic. At present, the ideal method of flame retardant modification of plastics is often to improve the fire resistance of plastics by adding prod...
