Embodiment 1
[0030] An environment-friendly flame-retardant composite material, comprising the following raw materials in parts by weight: 30 parts of adsorption resin, 5 parts of flame-retardant filler, 1 part of ammonium polyphosphate, 10 parts of carboxymethyl starch, 5 parts of nanocellulose, 60 parts of acrylic acid, two 60 parts of methyl diallyl ammonium chloride, 0.5 parts of N,N'-methylenebisacrylamide, 60 parts of glycerol, 130 parts of absolute ethanol, 1 part of ammonium persulfate and 1 part of coupling agent;
[0031] The environmentally friendly flame-retardant composite material is made by the following steps:
[0032] In the first step, add nanocellulose and absolute ethanol to the reaction kettle, raise the temperature to 80°C, then add acrylic acid and dimethyl diallyl ammonium chloride dropwise to the reaction kettle, and control the dropping rate to 2mL / min. After the dropwise addition, ammonium persulfate was added to the reaction kettle, and the first mixture was obt...
