1. a basalt fibre and polypropylene hybrid vehicle interior trim foam material, comprise and compound put into cone twin screw extruder and extrude as foam material, it is characterized in that:

  • adopt basalt fibre and polypropylene mixture manufacturing automotive trim foam material production method to divide the following step to carry out;

    Step 1, parts by weights get basalt fibre 40 ~ 59.9%, maleic anhydride grafted polyethylene 40 ~ 58%, KH-550 silane coupling agent 0.1 ~ 2%, put into stirrer mix and blend 10 ~ 15 minutes;

    Step 2, the material after stirring put into single screw extrusion machine extrude after through water-cooled, air-dry, then it is stand-by to be cut to pellet by dicing machine;

    Step 3, the polypropylene 75 ~ 88% weight fraction being got the trade mark 040, Cellmic C 121 3 ~ 5%, ethylene-vinyl acetate copolymer 5 ~ 10.65%, carbon black 1.5 ~ 3%, α

    crystal-type nucleater 0.1 ~ 0.3%, put into mixing machine stir 5 ~ 8 minutes, again by dicumyl peroxide 0.01 ~ 0.05%, pentaerythritol triacrylate 1 ~ 2%, whiteruss 1 ~ 3%, add in the acetone of 0.39 ~ 1%, add in mixing machine after being configured to acetone soln, then stir 10 ~ 15 minutes;

    Step 4, get the stand-by pellet 30 ~ 40% of step 2 and step 3 material 60 ~ 70% is stirred for compound;

    Step 5, above-mentioned compound put into cone twin screw extruder and extrude as foam material.
