Description
Technical Field
[0001] The utility model belongs to the technical field of flame retardant production, and particularly relates to a mixing and drying device for flame retardant production. Background Art
[0002] A flame retardant is a functional additive that imparts flame retardancy to flammable polymers, mainly designed for the flame retardancy of polymer materials; there are various types of flame retardants, which are divided into additive flame retardants and reactive flame retardants according to the usage method. Additive flame retardants are added to polymers by mechanical mixing methods to make the polymers flame retardant. Currently, additive flame retardants mainly include organic flame retardants and inorganic flame retardants, halogen-based flame retardants (organic chlorides and organic bromides) and non-halogen. Organics are represented by some flame retardants such as bromine-based, phosphorus-nitrogen-based, nitrogen-based, red phosphorus and its compounds, and inorganics are mainly flame retardant systems such as antimony trioxide, magnesium hydroxide, aluminum hydroxide, and silicon-based. Reactive flame retardants participate in the polymerization reaction as a monomer, so that the polymer itself contains flame retardant components. Its advantage is that it has less influence on the use performance of polymer materials and has long-lasting flame retardancy;
