Abstract

The invention relates to the field of preparation of new materials, and concretely relates to a method for preparing a cerium-containing bio-based material. The method comprises the following steps: modifying a lignin-based bisphenol monomer, adding 20-25 parts of the modified lignin-based bisphenol monomer, 0.3-0.7 part of sodium alpha-olefin sulfonate and 50-70 parts of dimethyl sulfoxide into ahigh-pressure reactor, filling the high-pressure reactor with carbon dioxide, performing a reaction, adding a diamine compound, and performing a polymerization reaction to obtain the cerium-containing bio-based material. The lignin-based bisphenol used as a raw material is rich in source and low in price, and also is a renewable resource, so the synthesized material has good mechanical properties, can be degraded, and is an environmentally-friendly material.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a method for preparing a cerium-containing bio-based material. Background technique [0002] Renewable resources include solar energy, wind energy, water energy, nuclear energy and biomass resources. Biomass resources are converted from solar energy into chemical energy by green plants through photosynthesis and stored in biomass. As a carbon-neutral biomass resource, it has unique advantages in replacing fossil resources. [0003] CN102822223B discloses a novel polyester polyol for obtaining polyurethane, which is environmentally friendly and easy to control the polyurethane reaction while maintaining the properties of polyurethane from polyester polyol, namely heat resistance, weather resistance and water resistance , and polyurethane is excellent in elongation and elastic modulus; and polyurethane obtained using the polyester polyol. This invention relates to a production...
