Description

technical field [0001] The invention relates to nano high-performance composite materials, which are cutting-edge new materials, and can be widely used in industries such as automobiles, building materials, electronics, home appliances, machinery, packaging, military industry, and high-tech fields such as electronic information, biotechnology, and aerospace. Preparation method of molecular emulsion / waste paper fiber / montmorillonite nanocomposite. Background technique [0002] Although the traditional white foamed plastic has the characteristics of low price, fire prevention and oil resistance, it is difficult to degrade (natural degradation takes more than 200 years), and its product waste forms a large amount of solid waste with a wide distribution range. The environment has caused extremely serious "white pollution". On the one hand, this has produced a large area of ​​visual pollution; on the other hand, it has brought more harmful and deeper ecological pollution. The l...
