Abstract

The invention discloses a flame-retardant melt-blowing nonwoven material which is prepared from, by weight, 80%-90% of PBT slices and 10%-20% of a composite flame retardant. The composite flame retardant is prepared from, by weight, 20%-30% of superfine aluminum hydroxide, 20%-30% of superfine magnesium hydroxide, 10%-20% of nanoscale attapulgite, 10%-20% of nano-zinc oxide, 1%-5% of a surfactant, 1%-5% of a coupling agent and 1%-5% of a smoke inhibitor. According to the flame-retardant melt-blowing nonwoven material, the problem that in the prior art, the flame retardancy of a melt-blowing nonwoven material is poor is effectively solved, therefore, the using range of the flame-retardant melt-blowing nonwoven material is wider, and development of a melt-blowing nonwoven material industry can be effectively promoted.

Description

technical field [0001] The invention relates to the field of nonwoven material manufacturing, in particular to a flame-retardant melt-blown nonwoven material and a preparation method thereof. Background technique [0002] With the continuous improvement of domestic living standards, the performance requirements of textiles are also getting higher and higher. Among them, flame retardancy has attracted more and more attention. Some industrially developed countries have formulated flame-retardant regulations for textiles very early, stipulating that curtains and curtains in public places such as theaters, hospitals, hotels, and clothing fabrics for the elderly, children, and disabled must meet certain flame-retardant standards. A survey report pointed out that the probability of fire accidents caused by flame-retardant textiles will be reduced by at least 20%. How to improve the flame retardancy of meltblown nonwoven materials, expand the application field of meltblown nonwove...
