Problems solved by technology

Although the flame retardant has good flame retardant effect, the product is washable and soft, it will release formaldehyde and endanger the health of consumers; at the same time, the phosphorus nitrogen flame retardant is tetrakis-hydroxymethylphosphoryl chloride (THPC) , this flame retardant adopts the most extensive Proban process for flame retardant treatment. The fabric is subjected to padding, drying, ammonia fumigation, oxidation, alkali washing, water washing, drying and other processes to complete the flame retardant treatment. This process makes the flame retardant treatment The processed fabric is soft to the touch, with little reduction in strength, washable, and basically maintains the excellent properties of cellulose fibers, but the process is very complicated, the production cycle is long, and formaldehyde will be released at the same time.
In addition, the newly developed Fyroltex HP in the United States is a kind of phosphate flame retardant, which is used for flame retardant of cotton fabrics. Although it is smokeless, has good flame retardant effect and strong washability, it will also release formaldehyde.
[0005] Currently, for cotton fabrics, flame retardants that do not generate formaldehyde are not durable, while durable flame retardants emit formaldehyde

Abstract

The invention discloses a non-color-fading environment-friendly composite flame retardant, and belongs to the technical field of synthesis of functional additives. The composite flame retardant comprises the following components including a reactive flame retardant, a nitrogen-containing organic matter and a catalyst, wherein the mass ratio of the reactive flame retardant to the nitrogen-containing organic matter to the catalyst is (50-150):(5-30):1:15. The invention also provides a preparation method of the non-color-fading environment-friendly composite flame retardant and application thereof. The composite flame retardant effectively enables pure cotton or cellulose fabrics to still have excellent flame retardance under the conditions of being free of color fading, achieving washing resistance and being free of formaldehyde.

Description

technical field [0001] The invention belongs to the technical field of synthesizing functional additives, and in particular relates to a colorless and environment-friendly composite flame retardant, a preparation method and an application thereof. Background technique [0002] Cotton fiber (or cellulose) is one of the most important natural fibers. Due to its good mechanical properties, biodegradability, air permeability, good dyeability and hydrophilicity, cotton fiber fabrics are widely used in many fields in people's daily life. For example: bedding, upholstery (carpets, furniture covers, cushions, etc.) and clothing fabrics, etc. [0003] But the cotton fabric that cotton fiber (or cellulose) produces belongs to combustible fabric, the fire that causes by it has seriously endangered the life and property safety of consumer. Therefore, while cotton fabric serves the daily life of consumers, it is also accompanied by fire hazards. In recent years, there have been more a...
