Abstract
The invention relates to a preparation method of a sponge type sound insulating pad for a vehicle. The method comprises the following steps: uniformly mixing cloth flowering, fused fibers and sponge particles, putting the mixture in a fluff storage case; then feeding into a drying room to manufacture a felt sound insulating pad semi-finished product; cutting the semi-finished product into a specific size, and heating in an oven; and pressing in a mould to form the finished product. Compared with the prior art, the floor sound insulating pad containing the sponge particles has excellent resilience performance and comfortable treading effect, can recover to the original state after being treaded frequently, and has excellent damping performance.
Description
Technical field
The present invention relates to a kind of preparation method of sound insulating pad, especially relate to the preparation method of a kind of automobile with the sponge-type sound insulating pad.
Background technology
The ground plate portion overwhelming majority only adopts multiple lamination coating to make part in the passenger accommodation of auto trade at present.Because floor area is foot-operated zone, the sound insulating pad part of ground Board position is frequent trample after, rebound performance can be worse and worse, i.e. the traveling comfort that part modification slowly, and influence is trampled.
Summary of the invention
The object of the invention is exactly that a kind of preparation method that good rebound performance and the comfortable automobile of trampling effect are arranged with the sponge-type sound insulating pad is provided in order to overcome the defective that above-mentioned prior art exists.
The object of the invention can be realized through following technical scheme:
A kind of automobile is characterized in that with the preparation method of sponge-type sound insulating pad this method may further comprise the steps:
(1) mix fine: with cloth bloom, fused fiber and sponge particle be by weight being (60～80): (20～30): mix (5～10), utilizes gas channel with three kinds of abundant shreddings of material and mix, and mixed raw materials is placed in the storage hair case;
(2) felt: will store up the composite material of hair in the case and become net, and send into and be made into felt sound insulating pad half-blank in the drying room with the air lay mode;
(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 process type again and promptly gets product.
Described fused fiber comprises compound polyster fibre or compound polypropylene fiber.
The length of described sponge particle is 10～15mm.
Drying room temperature in the said step (2) is 160～190 ℃, and the length of the halt of composite material in drying room is 2～4min.
Oven temperature in the said 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, and guarantees after frequent trampling, can be returned to original state, and good damping performance is arranged.
