AI Technical Summary
Technical Problem
Existing tent canvas is flammable and poses a fire safety hazard, especially when it is easily burned during travel.
Method used
An alkaline solution is used to remove grease and impurities on the fiber surface, and a coating slurry is made by mixing polyurethane resin, microencapsulated red phosphorus, nano-magnesium hydroxide, etc., which is applied to the base fabric and covered with a cold-resistant surface layer to enhance the cold resistance and flame retardant properties of the base fabric.
Benefits of technology
The cold resistance and flame retardancy of tent canvas are improved, which reduces the risk of fire and enhances safety.
