Determination and formulation analysis of flame retardants

A brief description of flame retardants.
Flame retardants are classified as additive and reactive flame retardants, as well as organic and inorganic flame retardants, which are mainly used to impart flame retardancy to polymer materials. The invention refers to adding flame retardant in polymer by mechanical mixing method, adding active flame retardant in polymer polymerization reaction, adding active flame retardant in polymer polymerization process, participating in the reaction in the form of monomer, and synthesizing as a part of polymer by chemical bond.
Two, the formula parameters of flame retardant.
Appearance: Powder or liquid color.
Solid content % : ≥85.
Spontaneous combustion temperature is 330~350℃.
Content: About 100ml or g.
Inspection period: about 10 days.
Iii. Classification of flame retardant components.
1, according to the bromine series, phosphorus series, nitrogen series, inorganic class;
2, according to the product is divided into: PP, PE, ABS, PC, nylon, etc.
3, according to the characteristics of: transparent, halogen-free, nano, etc.;
According to the mechanism, it can be divided into additive type and reactive type;
5, according to the shape is divided into: liquid, solid, etc.
Four, flame retardant composition determination and formula analysis.
After the polymer activation treatment, flame retardant has good processing thermal stability, compatibility with resin, dispersion and mechanical properties, mainly used in cable material, automotive electronic wire, thin-wall cable, electronic screen, engineering plastics, etc. Carbonized flame retardant composition analysis can be found detection technology, analysis is fast and accurate. Flame retardant products are generally added less, low halogen content, high flame retardant, if you get high quality flame retardant products to understand the raw materials, find no loss.
