Composite flame-retardant smoke suppressor

Abstract

The invention relates to a composite flame-retardant smoke suppressor, and belongs to the field of flame-retardant additives. The composite flame-retardant smoke suppressor can play a role in retarding flame and reducing the generation of harmful gas at the same time. The composite flame-retardant smoke suppressor is prepared from the following components in percentage by mass: 20 to 40 percent ofmagnesium hydroxide, 10 to 15 percent of aluminum hypophosphite, 10 to 15 percent of aluminum hydroxide, 10 to 15 percent of micropore silicon dioxide powder, 5 to 10 percent of zinc borate, 5 to 10percent of magnesium aluminum hydrotalcite, 4 to 8 percent of smoke-suppressing catalyst, 3 to 6 percent of high-activity magnesium oxide and 1.5 to 2 percent of coating agent. The composite flame-retardant smoke suppressor is halogen-free, and can adsorb and absorb acidic and toxic gas during combustion of organic matters. The fact that components of different temperatures sequentially act in a coordinating way is taken into full consideration, and meanwhile reduction in the formation of carbon black particles is catalyzed. Moreover, the acidic gas is absorbed while harmful substances are adsorbed through the high-activity magnesium oxide and porous silicon dioxide.

Description

technical field [0001] The invention relates to a composite flame-retardant smoke suppressant, which belongs to the field of flame-retardant additives. Background technique [0002] Flame retardant is an additive that can improve the flame retardancy and self-extinguishing properties of flammable or combustible materials. It is one of the main additives for important fine chemical products and synthetic materials. Flame retardants continue to develop with the development of synthetic materials. Due to the increasing calls for flame retardant and disaster prevention worldwide and the improvement of flame retardant regulations, the research, development, production and application of flame retardant chemicals are directly promoted. According to the types of flame retardant elements, flame retardants can be divided into halogen (bromine and chlorine), organophosphorus and halogen-phosphorus, phosphorus-nitrogen, nitrogen, silicon, antimony, aluminum-magnesium, inorganic Phosph...

AI Technical Summary

Problems solved by technology

However, the disadvantages of halogen-antimony flame retardants are that more smoke, corrosive gases and some toxic products (dioxins) are generated during combustion or thermal cracking, and their light resistance is poor.
