Insulated non-woven fabric sound-absorbing cotton and preparation method thereof

Abstract

The invention discloses insulated non-woven fabric sound-absorbing cotton, which consists of a top surface layer, a back surface layer and a fiber cotton layer clamped between the top surface layer and the back surface layer, wherein the top surface layer and the back surface layer are made of a non-woven fabric. The non-woven fabric is prepared from the following raw materials in parts by weight with a melt blowing method: 100 parts of isotatic polypropylene, 5-7 parts of titanium dioxide, 2-3 parts of cellulose acetate, 1-2 parts of antioxidant 168, 12-15 parts of chlorinated paraffin, 12-15 parts of wheat bran, 3-4 parts of active carbon, 2-3 parts of common clubmoss herb, 1-2 parts of garden balsam stem, 2-3 parts of dandelion and 4-5 parts of aid. Due to the adoption of the isotatic polypropylene, the sound-absorbing cotton has the characteristics of heat resistance, corrosion resistance and freeness from toxicity and odor, and is high in tensile strength; the common clubmoss herb, garden balsam stem, dandelion and the like are applied, so that aromatic smell and an antibacterial action are realized; carbonization treatment is performed by using the wheat bran, so that moisture absorption and odor removal are realized; the chlorinated paraffin is applied, so that a good flame retarding effect and high insulating performance are realized; the titanium dioxide is applied, so that sunshine resistance, cracking resistance and freeness from discoloration are realized.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing cotton, in particular to an insulating non-woven 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 so...
