Problems solved by technology

[0004] Sb 2 o 3 Generally, when used as a flame retardant, it can work synergistically with other halogen-based flame retardants to produce better results, but it contains halogen atoms, which will cause a lot of smoke and toxic and corrosive harmful gases when burned, and in a fire. Eighty percent of the fatal accidents in China are caused by suffocation of smoke and harmful gases
Chinese invention patent CN201210143074.1 discloses a low-smoke type antimony trioxide compound flame retardant and its preparation method. The flame retardant is composed of antimony trioxide, hydrotalcite, zinc borate, montmorillonite and coupling It is compounded with a combination of additives, which have good flame retardant and smoke suppression properties, but most of these components are hydrophilic and oleophobic, and have poor compatibility with the polymer matrix, resulting in mediocre or poor mechanical properties of the polymer. Decrease, affecting the use effect of polymer products

Abstract

The invention discloses a composite antimony trioxide flame retardant and relates to the technical field of flame retardants. A composite antimony trioxide flame retardant disclosed by the invention is composed of 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 ester amine salt, 2-3 parts of coupling agent and 3-5 parts of organic copper salt heat stabilizer; the phosphate ester amine salt is polymerized from pentaerythritol, phosphorus pentoxide and The mass ratio of the pentaerythritol, phosphorus pentoxide and isobutyramide is (1.5-2.5):1:(1.8-3.6). The composite antimony trioxide flame retardant provided by the present invention has good compatibility among the components, has excellent interfacial bonding force with plastic materials, and is uniformly dispersed, so that the applied plastic products have excellent flame retardancy Sex and smoke suppression, and improve the mechanical properties of plastic products.

Description

Technical field [0001] The present invention belongs to the technical field of flame retardants, in particular to a composite antimony trioxide flame retardant and a preparation method thereof. Background [0002] Antimony trioxide (Sb 2 O 3 ), white crystal powder, yellow when heated, cooled back into white or gray, relative density of 5.22 ~ 5.67, mainly used in white pigments, paints and plastics, can play a role in 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 the surface polarity of the two is different, Sb 2 O 3 The powder is hydrophobic, while the surface of the polymer matrix is lipophilic and hydrophobic, and the difference between the two is very large, resulting in poor compatibility, and the interaction between the interfaces is small, Sb 2 O 3 The direct addition of the materia...
