Problems solved by technology

For example, CN201611108731.3 discloses the use of a large amount of antimony trioxide in a polycarbonate composition with flame retardant function, but antimony trioxide will also cause polycarbonate to degrade at the same time, and the actual flame retardant application effect is not good

Abstract

The invention provides a production process of halogen-free flame-retardant socket granules, and belongs to the technical field of flame-retardant socket materials.According to the production process of the halogen-free flame-retardant socket granules, polycarbonate is adopted as a main raw material, and phenyl methyl silicone resin, phenyl phosphate, phenyl methyl silicone resin and the like are adopted as auxiliary materials for flame-retardant blending extrusion granulation; the high-flame-retardant performance is achieved, the impact resistance and the electrical performance are good, and production and use of the socket are met; phosphorus phenyl phosphate, phenyl methyl silicone resin, phenyl methyl silicone resin and the like are compounded for use, so that the flame retardant has relatively high flame retardant efficiency and heat resistance, and does not volatilize or thermally decompose in the processing process, so that the flame retardant generates a synergistic effect, and V-0-level flame retardance of polycarbonate is realized under the condition of relatively low addition amount of the flame retardant; on the basis of well maintaining the original mechanical properties of PC, the flame-retardant PC alloy has good flame retardance and electrical properties.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant socket materials, in particular to a production process of halogen-free flame-retardant socket pellets. Background technique [0002] PC itself has good flame retardant performance, the oxygen index is about 25%, and it is self-extinguishing. At present, the halogen-free flame retardants used for PC mainly include phosphorus-based flame retardants, sulfonate-based flame retardants, silicon-based flame retardants, and boron-based flame retardants. The above halogen-free flame retardants can basically make the material reach UL94 V0 level. PC needs a higher level of flame retardant in many occasions. Traditional flame retardant polycarbonate materials are often flame retardant with brominated flame retardants. Brominated epoxy oligomer, the flame retardant grade reaches UL94V-0 level, and has little effect on its thermal deformation temperature, and can even increase the impact strength of ...
