Abstract

The invention belongs to the material science field, in particular to a basic biomass synthetic resin and a preparation method and an application thereof. The basic biomass synthetic resin is prepared by the following steps: taking acidity regulator to prepare a water solution with pH value of 6.0-10.0, adding plant protein powder in the water solution under the stirring state; adding a molecular structure modifying agent under the stirring state, performing the modifying reaction for 15-240 min at 5-75 DEG C; sequentially adding modified starch and a resin assistant, performing the polymerization reaction for 15-240min at 5-90 DEG C, adding preservative in a reaction system within the last 5-20min of the polymerization reaction; adding or not adding packing after finishing the reaction, and stirring uniformly to obtain the basic biomass synthetic resin, wherein the part of the materials is taken by weight. The basic biomass synthetic resin has wide application range on the respect of preparing bonding adhesive or coating.

Description

(1) Technical field [0001] The invention belongs to the field of material science, and in particular relates to a basic biomass synthetic resin and its preparation method and application. (2) Background technology [0002] Biomass synthetic resin refers to a kind of moderate modification of natural macromolecules such as protein, starch or carbohydrate by physical or chemical means, so that it has some characteristics of synthetic resin, and can replace traditional synthetic resin in certain application fields. At the same time, it is a new type of biomass synthetic material with the characteristics of completely pollution-free degradation. [0003] The synthesis principle of biomass synthetic resin is mainly to use mild chemical reagents or enzyme preparations to transform the complex natural macromolecular conformation into a simple chain structure in the reaction system with water as the solvent, so that the chemical functional groups originally hidden inside the molecule...
