Preparation method for difficult-flammable and fire-retardant cloth

Abstract

The invention provides a preparation method for difficult-flammable and fire-retardant cloth. The preparation method comprises the following steps of (1) dissolving boric acid, zinc borate and aluminum borate in water; (2) immersing a cloth raw material in a solution prepared by the step (1) for at least 13 hours, kneading the cloth raw material every four hours, stopping brushing at the last 6 hours after immersing, and keeping a standing state; (3) air-drying the raw material obtained by the step (2), and spinning the cloth raw material into the cloth after air-drying; (4) immersing the cloth obtained by the step (3) in a B60-1 crylic acid solution, taking out the cloth after immersing and air-drying the cloth; and (5) spreading the cloth obtained by the step (4) smoothly, and spraying A60-1 modified amino-based expansive fire-retardant coating on the surface of the cloth. The preparation method is strong in operationality and simple in application for industrial production. The cloth has relatively stable fire-retardant function. The outermost layer coating of the cloth can expand when a fire breaks out, so that the fire is prevented from extending toward the inner layer of the cloth and the cloth has relatively good fire-retardant performance.

Description

technical field [0001] The invention relates to a preparation method of flame retardant and fireproof cloth, which is a processing method of textile cloth which can prevent fire and effectively prevent fire from extending to the inner layer of the cloth, and belongs to the field of textile processing. Background technique [0002] With the development of the textile industry, textiles have been applied to a wider range of fields. Fire is a disaster that causes great harm to people's life safety and property safety. When a fire occurs, people's resistance is limited. Especially, with the urbanization construction, people's lives and offices are becoming more and more As the buildings become denser and denser, the number of people per unit area increases, and the number of floors of the building increases. People rely more on elevators to pass up and down. When a fire occurs, congestion in the stairs is more likely to occur. It hurts more people and easily traps more people. ...
