Abstract

The invention discloses phosphorus-containing fire retardant as well as a preparation method and an application thereof, aiming at solving the problems that the application of phosphonitrilic chloride trimer in fabric flame retardancy is limited as the phosphonitrilic chloride trimer is poor in water solubility in the cellulosic fiber fabric flame-proof treatment process, is hard to apply to the cellulosic fiber fabric flame-proof treatment process, and moreover the flame retardant which is frequently used in the conventional flame-proof treatment process is toxic and toxic substances can be generated and the smoke suppression property is poor when the flame retardant fabric is combusted. The structural formula of the phosphorus-containing fire retardant is shown in the specification. The preparation method comprises the following steps: mixing phosphonitrilic chloride trimer with diethyl ether, adding degraded chitosan and pyridine, standing, performing suction filtration, washing, purifying and drying, thereby obtaining the phosphorus-containing fire retardant. The application comprises the following steps: 1, destarching and boiling to smelt; 2, respectively soaking and extruding for three times; and 3, drying, thereby obtaining a linen fabric after phosphorus-containing fire retardant treatment. The invention discloses the phosphorus-containing fire retardant, the preparation method and the application thereof.

Description

technical field

[0001] The invention relates to a flame retardant and a preparation method and application thereof. Background technique

[0002] With the improvement of people's material living standards, the comfort and elegance of the living environment has been paid more and more attention. Therefore, places such as hotels, hotels, and households consume a large amount of high-grade decorative cloth. Linen, once known as the "Queen of Natural Fibers", has noble and gorgeous textiles with soft luster and soft touch. It has been used by royal families and nobles for curtains, tablecloths, tapestries, wall coverings and other decorative cloths since ancient times. It is applied to decorative cloths such as automobiles, cruise ships, and airplanes, but flax fibers are extremely flammable, and the use of its fabrics for decoration will increase many unsafe factors. Investigations show that fires caused by interior decorative fabrics must be given great attention. In order to...
