Abstract

High-strength sound absorbing cotton is composed of a top face layer, a back layer and a fiber cotton layer clamped between the top face layer and the back layer. The top face layer and the back layer are made of nonwoven cloth, the nonwoven cloth is formed by, by weight, 100 parts of isotatic polypropylene, 3-4 parts of talcum powder, 2-3 parts of tremolite powder, 10-12 pars of chlorinated paraffin, 1-2 parts of ethanediamine, 1-2 parts of aluminum hydroxide, 7-9 parts of tributyl citrate, 2-3 parts of diphenyl silanediol, 1-2 parts of cross linker TAIC, 2-3 parts of medical stone powder, 1-2 parts of acrylamide, 10-12 parts of diatomite, 2-3 parts of mum, 1-2 parts of white paeony root, 1-2 parts of semen cassiae, 2-3 parts of uncaria and 4-5 parts of auxiliary through a melt-blowing method. The high-strength sound absorbing cotton has the advantages that the high-strength sound absorbing cotton is heat-resistant, corrosion-resistant and nontoxic and odorless, the nonwoven cloth is good in cohesiveness, high in strength and good in flame retardancy, and the high-strength sound absorbing cotton has functions of aromatizing smell and refreshing, can absorb harmful gas and peculiar smell and is environment friendly and energy saving.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing cotton, in particular to a high-strength sound-absorbing cotton and a preparation method thereof. Background technique [0002] At present, sound-absorbing quilts are widely used in architectural decoration and automobile interior decoration. With the increase of car ownership and people's higher requirements for the environment, the role of sound-absorbing cotton is becoming more and more important. The current sound-absorbing cotton has the following deficiencies: (1) release harmful organic substances, endangering human health; (2) insufficient adhesion, easy to disperse, and poor tensile strength; (3) limited sound-absorbing effect; (4) deviation in thickness and weight Larger, unable to meet the requirements of the automotive industry for this product; (5) The flame retardant effect is not enough, and the safety is not high. Therefore, it is particularly important to study sound-abso...
