Polyvinyl butyral foam material

Polyvinyl butyral foam material

1. Mixing: First, the polyvinyl butyral diaphragm used is broken into pieces in a plastic crusher, dried for 1 hour at 12:00 in an oven at 60 ° C; then, each piece is called mass 50g, and then, according to the formula, the mass of each raw material is evenly measured and mixed in a torque rheometer (temperature 100OCC, speed 60R, AINR, mixing for 10 min). Then formed on a 120 mils or 120 mm or 1 ITLM mold (the upper and lower plates of the flat plate vulcanizing machine are 100 °C and the pressure is 10 MPa for 5 min).

2. Foam molding: The upper and lower plates of 180 °C polyvinyl butyral molding plate placed in 120 mm × 120 mm×1 mm, foaming mold in the vulcanizing machine (curing plate temperature, pressure of 0 MPa, time 10 minutes). Finally, a polyvinyl butyral foam material is prepared from molded foam.
