Abstract

The invention discloses a halogen-free flame-retardant finishing agent and a preparation method thereof. The finishing agent comprises 5-9 parts of zirconium hydroxide, 5-12 parts of calcium hydroxyl phosphate, 3-7 parts of diammonium hydrogen phosphate, 12-17 parts of tetrakis hydroxymethyl phosphonium sulfate, 5-8 parts of hydroxyethyl methacrylate, 3-6 parts of octadecylamine polyoxyethylene ether, 15-25 parts of polyethylene glycol 400 and 135-165 parts of water. The preparation method comprises the following steps: (1) mechanically grinding zirconium hydroxide, calcium hydroxyl phosphate and diammonium hydrogen phosphate; and (2) taking the materials comprising 5-9 parts of zirconium hydroxide, 5-12 parts of calcium hydroxyl phosphate, 3-7 parts of diammonium hydrogen phosphate, 12-17 parts of tetrakis hydroxymethyl phosphonium sulfate, 5-8 parts of hydroxyethyl methylacrylate, 3-6 parts of octadecylamine polyoxyethylene ether, 15-25 parts of polyethylene glycol 400 and 135-165 parts of water, stirring, and preserving to obtain the halogen-free flame-retardant finishing agent.

Description

technical field [0001] The invention belongs to the field of textile finishing, and relates to a flame-retardant finishing agent and a preparation method thereof, in particular to a halogen-free flame-retardant finishing agent and a preparation method thereof. Background technique [0002] With the densification of urban population, the high-rise of residential buildings, the concentration of social wealth and the modernization of material life, the consumption of various textiles is increasing rapidly, and the fires caused by textiles are also increasing, causing casualties and major economic losses. loss. In particular, various interior decoration fabrics such as curtains, curtains, wall coverings, carpets, furniture fabrics and bedding are easy to burn, and industrial, aerospace and military textiles are also urgently required to be fire-resistant. According to statistics, the annual sales volume of flame-retardant textiles in my country is only about 2 million meters, w...
