Abstract

The invention discloses a composite antimony trioxide flame retardant, belonging to the technical field of flame retardants. The omposite antimony trioxide flame retardant disclosed by the invention is prepared from the following raw materials in parts by weight: 40-60 parts of surface-modified antimony trioxide, 10-30 parts of silane modified halloysite nanotubes, 20-30 parts of phosphate amine salt, 2-3 parts of a coupling agent and 3-5 parts of an organic copper salt heat stabilizer, wherein the phosphate amine salt is formed by polymerizing pentaerythritol, phosphorus pentoxide and isobutyramide, and a mass ratio of the pentaerythritol to the phosphorus pentoxide to the isobutyramide is (1.5-2.5): 1: (1.8-3.6). The components of the composite antimony trioxide flame retardant provided by the invention have very good compatibility; and the composite antimony trioxide flame retardant has excellent interface bonding force with a plastic material, is uniformly dispersed, allows a plastic product using the composite antimony trioxide flame retardant to have excellent flame retardance and smoke suppression performance, and improves the mechanical properties of the plastic product.

Description

technical field [0001] The invention belongs to the technical field of flame retardants, in particular to a composite antimony trioxide flame retardant and a preparation method thereof. Background technique [0002] Antimony trioxide (Sb 2 o 3 ), white crystal powder, yellow when heated, and turn white or gray again after cooling, relative density is 5.22-5.67, mainly used in white pigments, paints and plastics, can play the role of pigments and flame retardant. [0003] Sb 2 o 3 As an efficient flame retardant synergist, it has been widely used in polymer materials such as plastics and rubber products. When it is applied to polymer products, on the one hand, because of the different surface polarities of the two, Sb 2 o 3 The powder is hydrophilic and oleophobic, while the surface of the polymer matrix is ​​oleophilic and hydrophobic. There is a large difference between the two, resulting in poor compatibility, and the interaction between the interfaces is very small....
