Phosphorus-nitrogen intumescent flame retardant, synthesis method therefor and use thereof |
| abstract |
This disclosure provides high-efficiency and low-energy-consumption synthetic methods of a series of phosphorus-nitrogen-based intumescent flame retardants and the use thereof in paint flame retarding. 1 part by weight of a phosphorization agent and 0.5-4.0 parts by weight of a nitrogen-containing foaming agent are uniformly mixed and stirred at room temperature, and an amount of water is further added to emit heat and initiate reaction. 0.5-3.0 parts by weight of a charring agent and 0.5-4.0 parts by weight of a hydroxy-containing polyfuctional crosslinking agent are then added, and reacted with stirring. An amine compound is finally added for neutralization until pH value is 5-8, and solid liquid separation is performed. The solid portion is dried to obtain a main body portion of a phosphorus-nitrogen-based intumescent flame retardant. The resultant filtrate is diluted with 1/3-2/3 volume of water, and a flame retardant product is obtained. This flame retardant product is mainly used in the flame retarding of paper and cotton fabrics. The main body and different proportions of other nitrogen-containing foaming agents and charring agents are uniformly mixed and pulverized into nano- and micro-scale, and a phosphorus-nitrogen-based intumescent flame retardant is obtained. The nano- and micro-scale phosphorus-nitrogen intumescent flame retardant is mixed into a paint at a weight ratio of 15-30%, to obtain a flame-retardant paint which is capable of maintaining mechanical and physical properties of the paint. The phosphorus-nitrogen-based intumescent flame retardant of this disclosure is an intumescent flame retardant having a synergistic effect of phosphorus and nitrogen. |
