Abstract
The invention discloses a method for finishing an environment-friendly flame-retardant waterproof coating fabric, comprising the following steps of: preparing a polyester fabric, carrying out pretreatment of water repellence, finishing a coating, carrying out after-treatment of water repellence and producing a finished product. The flame retardant adopted by the method is a layered anion inorganic magnesium-aluminium hydrotalcite which is similar to the magnesium hydroxide and the aluminum hydroxide in structure and composition. The layered anion inorganic magnesium-aluminium hydrotalcite can release a large amount of water and carbon dioxide after being heated to decompose and absorb a large amount of heat at the same time so that the temperature of a combustion system is reduced. The water vapour and the carbon dioxide released after the layered anion inorganic magnesium-aluminium hydrotalcite is heated to decompose have the functions of diluting and blocking combustible gases. The aluminum and magnesium oxides generated from thermal decomposition and the carbide formed during the combustion of polymer materials can form a protective film on the surface of the material so that the further intrusion of oxygen is blocked and the flame-retarding effect is achieved. The solid product generated from the decomposition of hydrotalcite particles has a very large specific surface area and strong alkalinity and can absorb the acidic gases and the smoke released during the thermal decomposition of the material to fulfill the function of suppressing and abating smoke.
