Abstract

The invention belongs to the technical field of polyester wadding production, and particularly relates to flame-retardant polyester wadding and a preparation method thereof. Aiming at solving the problems that existing polyester wadding needs auxiliary external force for sterilization and is poor in flame-retardant effect, the invention provides the following solution that: the flame-retardant polyester wadding comprises the following raw materials in parts by weight: 30 to 50 parts of apocynum venetum fiber, 15 to 25 parts of gastrodia elata, 15 to 19 parts of dimethyl siloxane, 16 to 18 parts of phosphonic acid modified nano titanium dioxide, 16 to 18 parts of a flame retardant, 6 to 10 parts of an impact modifier, 6 to 10 parts of graphene powder, 6 to 8 parts of vegetable gum, 4 to 8 parts of a processing aid, 5 to 7 parts of 2, 6-dimethyl-2, 6-octadiene aldehyde, 2 to 4 parts of a lubricant, 1 to 2 parts of an initiator, and the balance deionized water. The preparation process issimple, the processing efficiency is high, the advantages of efficient sterilization and good flame retardant effect are achieved, the production cost is low, and large-scale processing and productioncan be carried out.

Description

technical field [0001] The invention relates to the technical field of glued cotton production, in particular to a flame-retardant glued cotton and a manufacturing method thereof. Background technique [0002] Sprayed cotton, also known as sprayed cotton, is a kind of nonwoven fabric. The principle of the formation of the glued cotton structure is to spray the adhesive on both sides of the fluffy fiber layer. Due to the certain pressure when spraying and the suction force when the lower vacuum absorbs liquid, the adhesive can also penetrate into the inside of the fiber layer. Mixture, the fiber layer after spraying the adhesive is dried and cured, so that the junction points between the fibers are bonded, and the fibers that are not bonded to each other still have a considerable degree of freedom. At the same time, in the three-dimensional network structure, there are still many voids containing air. Therefore, the fiber layer has a porous, high bulky thermal insulation ef...
