Embodiment 1
[0027] A continuous glass fiber reinforced polyethylene prepreg tape, made by the following method:
[0028] (1) 100 parts of low-density polyethylene resin matrix; 5 parts of toughening agent POE; 3 parts of compatibilizer (polyethylene grafted maleic acid); antioxidant (tetra[β-(3,5-di-tert-butyl Base-4-hydroxyphenyl) propionate] pentaerythritol ester): 0.4 parts; three [2.4-di-tert-butylphenyl] phosphite: 0.2 parts) a total of 0.6 parts; alkali-resistant glass fiber 40 parts;
[0029] (2) Adopt the feeding sequence of linear low-density polyethylene resin, compatibilizer, toughener, and antioxidant, and add low-density polyethylene, polyethylene grafted maleic acid, POE, and anti-oxidant in the high-speed mixer in sequence. Oxygen, mix evenly and then seal, the mixing speed is 400r / min, and the mixing time is 60s;
[0030] (3) Add the low-density polyethylene material mixed in step (2) to the hopper of the single-screw extruder, ready to be extruded and coated. The contin...
