Embodiment 1
[0046] A special material for expressway protective barriers and its preparation method, which uses glass fiber and matrix resin polyvinyl chloride (PVC) to compound, and treats the surface of the glass fiber with a coupling agent and the matrix resin polyvinyl chloride (PVC) through a modifier. PVC) after modification, grafting and cross-linking the olefinic bond of the coupling agent connected to the glass fiber with the matrix resin polyvinyl chloride (PVC), kneading to form a composite material, and then granulating according to the conventional method to obtain A special material for highway protection barriers. Among them, the formula (by weight and mass parts) of the special material for the highway protective barrier includes at least the following materials:
[0047] Base resin polyvinyl chloride (PVC) 100 parts;
[0048] Acrylate series modifier (ACR) 8-10 parts;
[0049] Chlorinated polyethylene modifier (CPE) 8-12 parts;
[0050] 15-25 parts of glass fiber;
