Abstract

The invention provides a modified isotatic polypropylene sound-absorbing cotton, comprising a top layer, a back layer and a cellucotton layer sandwiched between the top layer and the back layer, wherein the top layer and the back layer are made of a non-woven fabric material, and the non-woven fabric material is prepared from the following raw materials by weight through melt-blowing: 12 to 15 parts of PET, 100 parts of isotatic polypropylene, 4 to 5 parts of calcined china clay, 1 to 2 parts of sodium potassium silicate, 5 to 7 parts of calcite powder, 1 to 2 parts of zinc acetate, 1 to 2 parts of ethylene bisstearamide, 12 to 15 parts of dimixo-octyl phthalate, 5 to 6 parts of oxidized polyethlene wax, 7 to 9 parts of diatomite, 1 to 2 parts of zirconium nitrate, 2 to 3 parts of Chinese angelica, 1 to 2 parts of tall gastrodia tuber, 1 to 2 parts of bighead atractylodes rhizome and 4 to 5 parts of an auxiliary agent. The sound-absorbing cotton provided by the invention has fragrant smell and an antibacterial effect, can adsorb harmful gas and moisture and remove bacteria and has the advantages of soft handle, a good bonding degree, strong tensile strength, excellent sound-absorbing performance and a good flame retardation effect.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing cotton, in particular to a modified isotactic polypropylene 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 ...
