Problems solved by technology

The above silicone oil treatment method improves the moisture absorption and agglomeration of piperazine pyrophosphate, and has good water resistance in a normal temperature environment, but the melting point of silicone oil itself is not high, and it is easy to soften again when heated, so that the modified product can withstand high temperature, high humidity and hot water. The water resistance becomes poor in the environment, and the powder is easy to agglomerate after long-term storage without isolation and dispersion treatment after silicone oil coating treatment

Abstract

The invention discloses a halogen-free flame retardant with good flame retardance and processability and a flame retardant resin composition. The halogen-free flame retardant with good flame retardance and processability is prepared from piperazine phosphate, melamine and derivatives thereof, a metal salt flame retardant synergist, a hyperdispersant, a low-melting-point lubricating flame retardantadditive and an organic sulfur-containing compound. The flame-retardant resin composition is composed of the halogen-free flame retardant with good flame retardance and processability and resin, andthe mass percent of the halogen-free flame retardant with good flame retardance and processability is 15-50%. The halogen-free flame retardant disclosed by the invention is excellent in flame retardance, relatively good in compatibility and dispersity in resin, smooth in surface of a flame-retardant product, free of white points and high in yield.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a halogen-free flame retardant and a flame retardant resin composition with good flame retardancy and processability. Background technique [0002] In the research of halogen-free flame retardant and the development of polymer material products, piperazine phosphate flame retardants show high-efficiency flame retardant performance, among which piperazine pyrophosphate has high thermal stability and char formation performance, and has been widely used In the halogen-free flame retardant materials of polypropylene and glass fiber reinforced systems. A flame retardant synthetic resin composition disclosed in U.S. Patent No. 4,599,375 in 1986, which contains (a) synthetic resin, (b) piperazine pyrophosphate, (c) melamine pyrophosphate, (d) titanium dioxide or two silicon oxide. In many patents such as CN101827885A, CN109503941A, CN104119610A, CN105061887A, etc....
