According to the information of the State Intellectual Property Office, Ningbo Tiandun Waterproof Material Co., Ltd. applied for A patent entitled "a kind of high flame retardant silicone canvas and its application", the public number CN 118704245 A, the application date is August 2024.

The patent abstract shows that the invention provides a high flame retardant silicone canvas and its application, which relates to the technical field of canvas. In this application, long carbon chain alkyl chloride is introduced on the basis of silicone flame retardant for grafting modification to improve the water repellency of silicone flame retardant. At the same time, hydrophobic microcapsule mixture is supplemented to further improve the water repellency of the finishing liquid, so that the finished canvas forms a superhydrophobic structure on its surface, and prolongs the service time of the flame retardant coating by giving the flame retardant hydrophobic. In addition, the phosphate-oxygen group in the silicone-type flame retardant water repellent will form a stable coke layer during combustion, thus isolating the contact between the substrate and heat and oxygen, while the silicon-containing group will participate in carbonization to improve the stability of the carbon layer, form a heat-resistant protective layer, and protect the base layer from burning, supplemented by the ionic liquid in the microcapsule with good weather flame retardant and free radical inhibition reaction ability. When the fabric is burning, it can effectively suppress the flame spread and burning rate, and further play a better flame retardant role.
