A kind of preparation method of the automobile enhancement mode car roof soundproof pad of straticulate structure, the method comprises the following steps:
(1) by polyethers and isocyanates be by weight 100: 150��100: 170 ratio mixed foaming, solidify, namely section obtains polyurethane foam material layer;
(2) punch on kraft paper, and cut out, obtain the layers of kraft paper that surface is ventilative;
(3) punching on the upper mould of mould with counterdie;
(4) kraft paper is passed through adhesives in the both sides up and down of polyurethane foam material layer, and put in mould, hot-forming.
On step (2) heifer paper, the diameter in hole is 0.1mm, pitch of holes 20mm �� 20mm.
Mold material described in step (3) is aluminum dipping form, the hollow structure being made up of upper mould and counterdie, sets reinforcement in mould, and reinforcement spacing is 100mm, and Rib Thickness is 30mm, and Mould walls thinner is 30mm.
All offering porose in step (3) on upper mould and counterdie, the diameter in hole is 3mm, pitch of holes 100mm �� 100mm.
