preparation example Construction

[0058] The preparation method of the novel 3D printing glass fiber composite material comprises the following steps:

[0059] S1: soak the glass fiber with coupling agent 560 to make primary glass fiber;

[0060] S2: Use a hard plastic crusher to initially crush waste plastics, and then use an intermittent stirring plastic washing machine to thoroughly clean the crushed waste plastics to remove surface dirt. After natural drying and selection, selected plastics are obtained;

[0061] S3: Put the selected plastic prepared in step S2 in a nitrogen or dry ice low-temperature pulverizer, pulverize the plastic at a temperature of -90--110°C for 2-3 hours, and obtain 400-600 mesh plastic fine particles after sieving ;

[0062] S4: The primary glass fiber prepared in step S1, the fine plastic particles prepared in step S1, asparagine, metaldehyde, PBT resin, tributoxyethyl phosphate, PET resin, tris(2,4-bis tert-butylphenyl) phosphite, stearic acid, polyacrylamide, specific synthet...
