Abstract

The invention discloses a method for preparing epoxy resin from Chinese herb residues. The method includes the first step of extracting lignin and cellulose in the Chinese herb residues with a steam explosion method, the second step of carrying out hydrogenation degradation on lignin and cellulose, and the third step of preparing the epoxy resin. According to the method, the Chinese herb residues obtained after explosion are used as raw materials, products are extracted respectively to prepare synthesis raw materials of the epoxy resin, and finally the synthesis raw materials of the epoxy resin react with epoxy chloropropane to obtain the epoxy resin. The product epoxy resin is obtained through the steps and has excellent properties such as strong chemical corrosion resistance, high mechanical strength, good electric insulativity and corrosion resistance.

Description

technical field [0001] The present invention relates to the synthesis of the product by the new technology steam explosion method of organic matter, and the product is rich in cellulose and lignin to prepare epoxy resin. Background technique [0002] Traditional Chinese medicine dregs come from the production of Chinese patent medicines, the processing and processing of Chinese medicinal materials, and the production of raw materials. The production of Chinese patent medicines brings the largest amount of dregs, accounting for about 70% of the total amount of dregs. With the rapid development of traditional Chinese medicine, my country has become a major producer of traditional Chinese medicine in the world, and the disposal of medicinal residues is also a major problem. The waste of traditional Chinese medicinal residues in major traditional Chinese medicine pharmaceutical factories is increasing, with an annual discharge of 30 million tons. Most of these traditional Chines...
