Abstract

The invention belongs to the field of textile assistants, and particularly relates to a flame-retardant fluoride-free waterproof agent for textiles and a preparation method thereof.The flame-retardant fluoride-free waterproof agent is prepared from, by weight, 20-50 parts of total monomers, 1-3 parts of an emulsifier, 0.5-1 part of a PH buffering agent, 0.05-0.3 part of an initiator and 50-70 parts of deionized water, and the flame-retardant fluoride-free waterproof agent is obtained through temperature and pressure reaction. The product provided by the invention effectively improves the defects of poor waterproof effect, poor washability, poor flame retardance and the like of a waterproof auxiliary agent in the prior art. The comprehensive performance is considered, the problems are solved, and meanwhile, the high-efficiency antibacterial property, the weather resistance and the like are achieved. It can be foreseen that the material has a wide market prospect in textile materials, and is especially suitable for the fields of home decoration, automotive trim, even outdoor use and the like.

Description

technical field [0001] The invention belongs to the field of textile auxiliaries, in particular to a flame-retardant fluorine-free waterproofing agent for textiles and a preparation method thereof. Background technique [0002] The waterproof treatment of the fabric is to reduce the capillary additional pressure of the fabric fiber and reduce the surface tension of the fiber by treating the surface of the fabric, so as to prevent water from penetrating the surface of the fabric, but at the same time it does not affect the air permeability of the fabric. Whether the clothes are comfortable to wear is an important consideration for consumers to choose clothes. After durable waterproof treatment, it can prevent moisture from penetrating into the clothing from the outside for a long time, giving the wearer a comfortable feeling. For this reason, durable water repellent treated fabrics are in high demand. [0003] Water repellents are divided into fluorine-containing water repe...
