Abstract

The application relates to the field of non-woven fabrics, and discloses a flame-retardant non-woven fabric and a preparation method thereof. The non-woven fabric is processed by a flame retardant treatment agent, and the flame retardant treatment agent includes the following raw materials in parts by weight: 20-25 parts of dimethyl methyl phosphate; 4-5 parts of zinc borate; 3-4 parts of ammonium sulfamate; 1 -2 parts of 5-methylisophthalaldehyde; 0.2-0.3 parts of catalyst; 6-8 parts of styrene-acrylic emulsion; 40-50 parts of deionized water; the preparation method is: S1. Preparation of flame retardant finishing agent; S2. None Flame retardant finishing of woven fabrics; this application has the following advantages and effects: the co-addition of dimethyl methyl phosphate and zinc borate with flame retardant effect plays a role of synergistic flame retardancy; the auxiliary components of styrene-acrylic emulsion form a homogeneous phase system; the polymer obtained by the polymerization reaction of ammonium sulfamate and 5-methylisophthalaldehyde can be carbonized under the dehydration of phosphoric acid, thereby forming a carbonized layer, which helps to isolate non-woven fabrics from oxygen and achieve flame retardancy the goal of.

Description

technical field [0001] The present application relates to the field of non-woven fabrics, in particular to a flame-retardant non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are called cloths because of their appearance and certain properties; non-woven fabrics are moisture-proof, breathable, flexible, lightweight, easy to decompose, free from Poisonous, non-irritating, rich in color, low in price, recyclable, etc.; for example, polypropylene (pp material) pellets are used as raw materials, and are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing coiling. made. [0003] However, the polypropylene raw materials used in the current non-woven fabrics on the market are hydrocarbon materials, which are more likely to cause combustion and cannot meet the needs of safety and fire prevention.
