Plastic flame retardant additive

Plastic flame retardant additive

Most plastics are flammable. With the wide application of plastics in construction, furniture, transportation, aviation, aerospace and electrical appliances, it has become an urgent issue to study the plastic flame retardant additive.

Plastic flame retardant additives suppress plastics combustibility of additives, most of them are in the periodic table first Ⅴ, Ⅶ and Ⅲ group element compounds; In particular, phosphorus, bromine, chlorine, antimony and aluminum compounds.

There are two kinds of flame retardant type and reaction type. The added flame retardant is mainly phosphatate and halogen phosphate, halogenated hydrocarbon, antimony oxide, aluminum hydroxide and so on. The advantage is easy to use, adaptable. However, due to the addition of 10% ~ 30 %, the properties of plastics are often affected.

Reactive flame retardants are actually monomers with flame retardant elements, so the effect on plastic performance is small. Common reactive flame retardants, such as halogenated anhydride for polyester, tetrabromobisphenol A used in epoxy resin, and phosphorus polyol for polyurethane. The flame retardant was first used in the United States, and after the 1960s, the amount of use increased after the plasticizer. The most used plastics are polyvinyl chloride, polystyrene, polyurethane foam, unsaturated polyester, ABS resin and polypropylene.

Most plastic products have flammability, which brings many hidden dangers to the application of their products.

To be precise, flame retardants are more appropriate as a non-flammable agent, because "hard fire" contains both flame retardant and smoke suppression, and the concept of flame retardant is more extensive. However, people have been used to the concept of flame retardant for a long time, so the plastic flame retardant additive mentioned in the literature is actually the general term for the flame retardant action and the anti-smoking function.

Add flame retardant agent was added to the polymer by mechanical mixing method, the polymer with flame retardancy, the additive flame retardants mainly include organic flame retardants and inorganic flame retardants, phosphorus-containing flame retardants (organic chloride and bromide) and non halogen. Organic is a series of flame retardants which are represented by bromine, phosphoric nitrogen, nitrogen and red phosphorus and compounds. The inorganic mainly consists of antimony trioxide, magnesium hydroxide, aluminum hydroxide, and the silicon system.

Reactive flame retardants is as a kind of monomer for polymerization, thus make the polymer itself contain flame retardant composition, its advantage is less affected the performance of polymer materials used, flame retardancy.

Flame retardant: it is mainly organic and inorganic, halogen and non-halogen.

Organic flame retardants are some flame retardants which are represented by bromine, nitrogen and red phosphorus and compounds.

Inorganic mainly antimony trioxide, aluminum hydroxide, magnesium hydroxide, silicone flame retardant system. Such as flame retardant is through some mechanism, give play to the role of the flame retardant such as absorption of heat, covering the role, inhibition of chain reaction, non-flammable gas choking effect, etc. Most flame retardants are designed to achieve flame retardation by several mechanisms.

Any heat released by burning in a relatively short time is limited, if you can in a relatively short time to absorb part of the fire produced by heat, the flame temperature will reduce, and ACTS on the surface will have radiation to the gasification of combustible molecules into free radicals can reduce quantity of heat, combustion reaction will be a certain degree of inhibition. Under the condition of high temperature, strong endothermic reaction happened flame retardants, absorb part of heat released by burning, lower the temperature of the fuel surface, effectively inhibit the formation of combustible gas, to prevent the spread of combustion.

The flame retardant mechanism of Al(OH)3 flame retardant is to increase the thermal capacity of the polymer to absorb more heat before the thermal decomposition temperature is reached, thus improving its flame retardant performance. This kind of flame retardant can give full play to the characteristics of the heat absorption when combined with water vapor, and improve its own flame retardant ability.

In combustible material after adding flame retardant, flame retardant agent can form a glassy or stability at high temperature foam layer, isolated from oxygen, with insulation, oxygen, prevent flammable gas to escape, the effect of flame retardant and to achieve. If the flame retardant of organophosphorus is heated, it can produce crosslinked solid or carbonized layer that is more stable. On the one hand, the formation of carbonation prevents the polymer from further pyrolysis, and on the other hand, it can prevent the internal thermal decomposition from entering the gas phase to participate in the combustion process.
