Embodiment 1

[0040] The application discloses a flame-retardant non-woven fabric and a preparation method thereof. The non-woven fabric is treated with a flame-retardant treatment agent. The preparation method includes the following steps:

[0041] S1. Preparation of flame retardant finishing agent; first mix styrene-acrylic emulsion and zinc borate evenly, then add dimethyl methyl phosphate, stir for 5 minutes; continue to add sodium sulfamate and catalyst thionyl chloride, and heat up to After 50°C, add 5-methylisophthalaldehyde, stir the polymer obtained after 30 minutes of reaction, finally add deionized water, and stir at 30°C for 50 minutes to obtain a flame retardant finishing agent;

[0042] S2. Flame-retardant finishing of non-woven fabrics; soak the non-woven fabrics in the flame-retardant finishing agent obtained in S1 and let it stand for 15 minutes; arrange the soaked non-woven fabrics between the two rubber rollers of the roller press, squeeze The excess liquid was removed by...

Abstract

The invention 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 treated by a flame-retardant treatment agent, and the flame-retardant treatment agent is prepared from the following raw materials in parts by weight: 20-25 parts of dimethyl methylphosphate, 4-5 parts of zinc borate, 3-4 parts of ammonium sulfamate, 1-2 parts of 5-methyl isophthalaldehyde, 0.2-0.3 part of a catalyst, 6-8 parts of a styrene-acrylic emulsion and 40-50 parts of deionized water; the preparation method comprises the following steps: S1, preparing the flame-retardant finishing agent; and S2, flame-retardant finishing of the non-woven fabric. The non-woven fabric has the following advantages and effects: dimethyl methylphosphate and zinc borate with flame retardant effects are added together to play a synergistic flame retardant effect; the styrene-acrylic emulsion assists the components to form a homogeneous system; and the polymer obtained by the polymerization reaction of ammonium sulfamate and 5-methyl isophthalaldehyde can be carbonized under the dehydration action of phosphoric acid to form a carbonized layer, thereby being beneficial to isolating the non-woven fabric from oxygen and achieving the purpose of flame retardancy.

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, and are called cloth because of their appearance and certain properties; non-woven fabrics are moisture-proof, breathable, flexible, light, easy to decompose, and non-woven. Non-toxic, non-irritating, rich in color, low in price, recyclable, etc.; for example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced in one continuous step by high-temperature melting, spinning, laying, and hot-pressing coiling. made. [0003] However, the polypropylene raw materials used in non-woven fabrics currently on the market are hydrocarbon materials, which are more likely to cause combustion and cannot meet the needs of safety and fire prevention.
