Described cloth is bloomed and is the fibrous cotton fiber of the leftover cloth shredding one-tenth of apparel industry generation.
Described fused fiber comprises composite terylene fiber or compound polypropylene fiber.
The particle diameter of described sponge particle is 10～15mm.
A kind of manufacture method of sponge type sound insulating pad is characterized in that, the method may further comprise the steps:
(1) mixed fine: with cloth bloom, fused fiber and sponge particle be by weight being (60～80): (20～30): mix (5～10), utilize gas channel with three kinds of abundant shreddings of material and mix, the raw material that mixes is placed in the storage hair case;
(2) felt: will store up the composite material of hair in the case and become net with the air lay mode, and send into and be made into felt sound insulating pad half-blank in the drying room;
(3) cutting: from drying room, take out felt sound insulating pad half-blank, this felt sound insulating pad half-blank is cut into the size of regulation;
(4) moulding: felt sound insulating pad half-blank places baking oven to heat, and places mould inner pressure to make type again and namely gets product.
Drying room temperature in the described step (2) is 160～190 ℃, and the length of the halt of composite material in drying room is 2～4min.
Oven temperature in the described step (4) is 180～220 ℃, and the length of the halt of felt sound insulating pad half-blank in baking oven is 4～5min.
Compared with prior art, the present invention adds the floor sound insulating pad that the sponge particle is made, and good rebound performance and the comfortable effect of trampling are arranged, guarantee after trampling frequently, can be returned to original state, good damping performance is arranged, and also have better sound-absorbing effect, reduce the noise of passenger accommodation; Guarantee that the passenger has quieter comfortable environment when driving.
