Environment-friendly flame-retardant noise-absorbing cotton and preparation method thereof

Abstract

The invention discloses environment-friendly flame-retardant noise-absorbing cotton which is composed of a top surface layer, a back surface layer and a cellucotton 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 flame retardant material. The flame retardant is prepared from the following raw materials in parts by weight through a melt-blowing method: 100 parts of isotactic polypropylene,3-4 parts of ammonium polyphosphate, 1-2 parts of titanium pigment, 2-3 parts of sodium xylene sulfonate, 3-4 parts of zinc borate, 1-2 parts of aluminic acid ester coupling agent DL-411, 14-17 parts of diisooctyl phthalate, 2-3 parts of activated alumina, 8-10 parts of medical stone, 3-4 parts of Chinese ephedra, 2-3 parts of ledebouriella root, 3-4 parts of cassia twig and 4-5 parts of accessory ingredient. The noise-absorbing cotton has a halogen-free, low-smoke, low-toxicity and environment-friendly flame-resistant system, meanwhile has the characteristics of heat resistance, corrosion resistance, no toxicity and no odor, is good in cohesive property and high in tensile strength; the noise-absorbing cotton further has aromatic flavor and an antibacterial effect, is capable of absorbing harmful gases and peculiar smell and is also capable of absorbing moisture, degerming, and releasing ion elements beneficial to a human body.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing cotton, in particular to an environmentally friendly flame-retardant 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 i...
