Problems solved by technology

The combination of zinc stannate and molybdenum trioxide can reduce the cost of raw materials to a certain extent, but it still needs to be added to a certain amount to show obvious flame retardant and smoke suppression effects, and the utilization rate of molybdenum is low
[0004] The invention patent with the publication number 201611089694.6 discloses an intercalated hydrotalcite smoke suppressant and its preparation method. The intercalated hydrotalcite smoke suppressant is prepared by co-precipitation method or clean hydrothermal reaction. The interlayer molybdate ion, octamolybdenum Acid radicals, cuprate radicals and stannate radicals, as well as iron and copper in laminates have a significant synergistic smoke suppression effect. The prepared intercalated hydrotalcite smoke suppressant is applied to rubber and plastic products with a mass fraction of 1%, and the maximum smoke The density can be reduced by 87.3%, and the smoke suppression performance is excellent. However, the preparation process of this method is complicated and the cost is high, which is not conducive to industrial production

Abstract

The invention discloses an environment-friendly flame-retarding and smoke-inhibiting agent and a preparation method thereof, the flame-retarding and smoke-inhibiting agent comprises the following components in parts by mass: 100 parts of an inorganic flame retardant and 0.5-2.5 parts of molybdenum-containing borate activator, of which the structural formula is as shown in the specification, wherein R is an alkyl group with 8-22 carbon atoms. The inorganic flame retardant is magnesium hydroxide, brucite, aluminum hydroxide or hydrotalcite. The environment-friendly flame-retardant smoke suppressant is prepared through a method of mechanically stirring and dispersing under a heating condition. The preparation method is simple, environmentally friendly and low in cost. The prepared environment-friendly flame-retardant smoke suppressant has good flame retarding and excellent smoke suppressing effect, and is wide in raw material source, low in price and high in thermal stability. The productcan be applied to high polymer materials such as polyvinyl chloride, nitrile rubber, polystyrene and unsaturated resin.

Description

technical field [0001] The invention belongs to the technical field of flame retardant and smoke suppressant, and in particular relates to a magnesium hydroxide flame retardant and smoke suppressant and a preparation method thereof. Background technique [0002] With the development of the polymer material industry, polymer materials are more and more widely used in various fields of the national economy. However, because most polymer materials are easy to burn, and a large amount of smoke and toxic gases are usually released during combustion, they become the primary factors that endanger the safety of people's lives and property in fires. Therefore, the research on smoke suppression of polymer materials has very important practical value. In the current research, the method of adding smoke suppressants is usually used to endow polymer materials with smoke suppression properties. Traditional smoke suppressants mainly include molybdenum compounds (such as α- MoO 3 , ammoni...
