Preparation method for cheap and easily prepared fireproof cloth

Abstract

The invention relates to a preparation method for cheap and easily prepared fireproof cloth. The preparation method comprises the steps of firstly immersing a textile cloth in a vinyl chloride-vinylidene chloride emulsion and a styrene-acrylic emulsion for at least 15 hours; taking the cloth out after immersion; air-drying the cloth; then immersing the cloth in a pure acrylic emulsion for at least 10 hours; air-drying the cloth after the cloth is taken out; and finally immersing the cloth in a polyvinyl acetate emulsion for at least 10 hours and air-drying the cloth after the cloth is taken out. The air-drying wind speed is not larger than 6 m / s; the air-drying environment temperature is not higher than 30 DEG C; and the moisture of the cloth after being dried is not larger than 20%, 25% and 15%. The preparation method can be easily implemented in operation, and allows the cloth forming stable fireproof performance. The fireproof coating on the surface of the cloth has a certain thickness, so that the cloth has relatively good hardness and stiffness and can keep good fireproof performance for a long time.

Description

technical field [0001] The invention relates to a method for preparing a low-cost and easy-to-manufacture fireproof cloth. It is a fireproof textile cloth. The cloth is soaked in a fireproof coating, and the inside and surface of the cloth are covered with fireproof materials to achieve the fireproofing of the cloth. The role belongs to the field of textiles. 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 The construction of buildings is more and more dense, and the number of people per unit area is increasing. The number of floors of buildings increases, and people rely more on elevators to pass up and down. When a fire occurs, congestion in the stairs is more likely to occur. Hurts people more, easily traps more people

At present, there are more and more fireproof materials, but most of them are expensive and have limited application fields. Textiles are materials that are easy to carry and low in price. However, the current textiles do not have fireproof functions.
