Problems solved by technology

For example, Chinese patents CN200810104239.8 and 200810063134.2 both use composite flame-retardant coating glue on polyester fabrics, but halogen-containing flame retardants are more and more restricted or even banned due to the problems of harming the human body and being unfriendly to the environment. In addition, the flame retardant performance achieved is limited, and the actual amount of flame retardant is also relatively large, which makes the fabric heavier.
Another Chinese patent: 2012105785875 also adopts the method of composite flame retardant coating glue, which is prepared from bisphenol F diglycidyl ether, epoxy resin, 2-phenylimidazole, and triglycidyl isocyanurate. Resin flame retardant, this technical solution is not ideal in terms of flame retardant efficiency, and the process is complicated and the cycle is long
[0005] In the article "Preparation and Application of Ammonium Polyphosphate Flame-Retardant Coating Adhesive", Mr. Liu Duokui added a char-forming agent to the ammonium polyphosphate flame-retardant coating adhesive system to overcome the problem of polyester droplet, but its flame-retardant effect and flame-retardant Durability, etc. are still not ideal, and there are also problems of ammonium polyphosphate absorbing moisture and causing moisture and heat migration

Abstract

The invention provides a flame-retardant coating adhesive for textile, a finishing method of flame-retardant fabric with the flame-retardant coating adhesive and the flame-retardant fabric with the flame-retardant coating adhesive. The flame-retardant coating adhesive for the textile is prepared through steps as follows: a microcapsule flame retardant DCAPP is added to a polyurethane coating adhesive, the viscosity of the mixture is adjusted to 5,000-6,500 cps, and the mixture is uniformly stirred and compounded to form the flame-retardant coating adhesive. The finishing method of flame-retardant fabric with the flame-retardant coating adhesive comprises the steps of at least two times of coating and baking. The flame-retardant fabric has the technical advantages as follows: the flame-retardant fabric has good flame retardance and flame-retardant durability, high flame retardant efficiency, low smoke amount as well as an excellent anti-dripping effect on polyester fiber fabric, and the finishing process is simple, meets the environmental protection requirement and is low in cost.

Description

technical field [0001] The application of the present invention relates to a flame-retardant coating adhesive for textiles, a fabric flame-retardant finishing method thereof, and a flame-retardant fabric. Background technique [0002] To endow textiles with flame retardant properties, due to different types of fabrics, different flame retardants, and different flame retardant treatment methods for fabrics, the flame retardant properties of the obtained flame retardant fabrics vary widely, and the flame retardant effects have their own advantages; and in The technical design also needs to meet the increasingly strict dual technical index requirements including fire safety standards and environmental protection standards. [0003] Among many fiber fabrics, polyester fabric itself has remarkable characteristics such as good elasticity, not easy to deform, strong and durable, corrosion resistance, insulation, and low price. It is widely used in textiles and industrial products, ...
