Background
With the increasing depletion of petroleum resources, the biomass formation of chemical product raw materials is a research hotspot, no exception is made for resin products, and in recent years, new resins using green plants as raw materials emerge endlessly. More renewable biomass resources are used to replace non-renewable resources, the consumption of petrochemical products in the plastic industry is reduced, and meanwhile, the problem of environmental pollution caused by production is reduced, so that the method is an important development direction of the current high polymer materials. The green economy and the low-carbon economy are combined, and the development space is higher.
The rich Cellulose in the plant body is treated by alkali, so that the relatively inert structure of the plant body can be damaged to a certain extent, the processing performance is improved, on the basis, chlorohexane is added for reaction, and a part of hydroxyl groups are replaced by ethoxy groups, so that the obtained Ethyl Cellulose (EC) is white or light brown powder, has good compatibility with materials such as resin, plasticizer and the like, has good film forming property, and can be used for coating, adhesive, cross-linking agent, pharmaceutical tablets and the like. The ethyl cellulose is easy to dissolve in organic solvents such as tetrahydrofuran, the solubility of the ethyl cellulose is different along with the substitution degree of hydroxyl in the cellulose by ethoxy, and the ethyl cellulose has a unique linear macromolecular structure, thereby being beneficial to further modifying the ethyl cellulose.
Tung oil (Tung oil) is an industrial vegetable oil obtained by mechanically squeezing, processing and refining the fruits of Tung trees, has the excellent characteristics of quick drying, high temperature resistance, corrosion resistance, water resistance and the like, can be used for synthesizing various fine chemicals such as plasticizers, biodiesel, lubricants, downstream products such as glycerin and the like, and is widely applied to the aspects of buildings, agricultural machinery, electronic industry and the like. The main components are alpha-eleostearic acid triglyceride and partial oleic acid, less saturated fatty acid is contained, and the molecular structural formula is shown in the figure. It can be seen that the barrel oil molecules have functional groups such as conjugated double bonds, carboxyl groups and the like, and can generate chemical reactions such as Diels-Alder reaction, Friedel-Crafts reaction, free radical polymerization, oxidative polymerization, amidation, ester exchange and the like. Because tung oil has the chemical characteristics of high toxicity, incapability of eating and higher activity than other vegetable oils, the consumption of edible oil can be reduced by taking tung oil as an industrial raw material, and the problem of shortage of grain and oil resources in China is solved.
The development and utilization of ethyl cellulose and tung oil resources are combined with the modification of high molecular materials, so that the method is favorable for popularizing the industrialization of biomass raw materials and developing the biomass raw materials to various and high-performance aspects, and is also favorable for improving the additional values of cellulose and tung oil products and expanding the application range.
