Abstract

The invention relates to the technical field of high-polymer materials and particularly relates to a halogen-free flame-retardant anti-static glass fiber reinforced nylon 66 particle and a preparation method thereof. The particle comprises the components by weight percent: 20-50% of nylon 66 resin, 10-40% of glass fiber, 15-25% of halogen-free flame retardant, 3-10% of antistatic agent, 2-8% of toughening agent, 0.1-0.8% of antioxidant and 0.2-1.5% of auxiliary processing aid. The halogen-free flame-retardant anti-static glass fiber reinforced nylon 66 particle is high in strength, modulus and mechanical strength, little in creep deformation, stable in size, good in flame retardant property, light in weight, easy to process and capable of resisting to statics and meeting the requirements of people for environment friendliness (composite ROHS (Restriction of Hazardous Substances Directive) and RECHA (Registration, Evaluation, Authorization and Restriction of Chemicals) laws and regulations). The preparation method provided by the invention is simple in operation and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant antistatic glass fiber reinforced nylon 66 particle and a preparation method. Background technique [0002] Due to the excellent mechanical properties of glass fiber reinforced nylon 66 particles, it can be widely used in various electronic and electrical equipment and home appliances, and it is one of the most widely used engineering plastics. [0003] However, most of the flame retardants used in most halogen-free flame-retardant antistatic glass fiber reinforced nylon 66 on the market are halogen-containing flame retardants, especially bromine-containing flame retardants represented by polybrominated biphenyls. However, with the successive implementation of ROHS, PAHS, Reach and other regulations by the European Union, these laws require that the use of such flame retardants is prohibited in electrical and electronic products placed in ...
