Problems solved by technology

However, the current finishing methods often need to use fluorine-containing materials as hydrophobic agents, or need to be dissolved in organic solvents, which has an impact on the environment
However, traditional flame retardants also produce toxic and corrosive gases, which are easy to cause harm to the human body.

Abstract

The invention provides a method for preparing a strong flame-retardant superhydrophobic fabric based on a foam finishing method. The steps of the method are as follows: (1) Add polydimethylsiloxane and curing agent to deionized water, ultrasonically vibrate and Stir, then add surfactant and foam stabilizer, then add copper phytate particles and ammonium polyphosphate, continue ultrasonic oscillation and stirring to obtain hydrophobic and flame-retardant finishing solution; (2) The hydrophobic and flame-retardant finishing solution prepared above is passed through mechanical Stir until foaming, apply the obtained foam on the fabric, and dry the fabric in an oven, thereby obtaining a superhydrophobic flame-retardant fabric. The preparation of superhydrophobic flame-retardant fabrics by this method does not use organic solvents, the method is simple, saves energy consumption, and reduces waste water discharge; the prepared superhydrophobic flame-retardant fabrics also have good superhydrophobic and self-cleaning effects, and can also slow down the drying process of fabrics. The burning speed in the flame, self-extinguishing immediately after leaving the fire source, has excellent flame retardant effect.

Description

technical field [0001] The invention relates to a method for preparing a strong flame-retardant superhydrophobic fabric based on foam finishing technology, and belongs to the technical field of textile functional finishing. Background technique [0002] Cotton textiles are indispensable items in people's daily life. Cotton fabrics have the characteristics of good air permeability, softness and skin-friendliness, and biodegradability. However, cotton fabrics are easily wetted by water and are flammable materials. Combustion not only easily causes huge economic losses, but also endangers personal safety. According to statistics, about 20% of residential fire accidents are caused by textile burning, and 50% of the deaths are caused by these fires. Researchers use surface treatment technology to perform functional finishing on fabrics, and obtain multifunctional fabrics such as superhydrophobic and flame-retardant, which have functions such as self-cleaning, anti-fouling, and f...
