Embodiment Construction
[0024] The present invention is further described below with embodiment.
[0025] The high-flow glass fiber reinforced flame-retardant AS special material for axial-flow fan blades includes 34-52% of acrylonitrile-styrene copolymer, 20% of alkali-free glass fiber, 3-6% of compatibilizer, and flame retardant in percentage by weight. 15-22%, flame retardant synergist 3-6%, high-efficiency lubricant 0.1-0.5% and antioxidant 0.2-1%.
[0026] The surface of alkali-free glass fiber is coated with silane-based sizing agent; the compatibilizer is styrene-maleic anhydride copolymer.
[0027] The flame retardant is decabromodiphenylethane; the flame retardant synergist is antimony trioxide.
[0028] The high-efficiency lubricant is pentaerythritol stearate.
[0029] The antioxidants are tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester and phosphite.
[0030] Prescription of the present invention is as follows:
