preparation example Construction

[0031] Preparation of fermentation product: put soybean dregs and sugarcane bagasse into a grinder in a mass ratio of 3:1 and grind and mix to obtain a ground product, and put the ground product and hydrochloric acid with a mass fraction of 10% into a three-neck flask at a mass ratio of 1:5, Place the three-necked flask in an ultrasonic oscillator, vibrate and mix for 120min at a frequency of 35kHz to obtain a mixed product;

[0032] Put the above mixed product in a steam explosion tank, send water vapor at a temperature of 230°C into the tank until the pressure in the tank rises to 1.5 MPa, seal the steam explosion tank, let it stand at constant temperature and pressure for 60 minutes, and then open the tank mouth to prepare the reaction Product, the above-mentioned reaction product and soybean powder are put into the planetary ball mill at a mass ratio of 5:1, and mixed and ground for 70 minutes under the condition of 300r / min at a rotating speed to prepare the reactant;

Abstract

The invention relates to a preparation method of a high-adhesion matting resin, and belongs to the technical field of resins. Soybean bean residues and bagasse undergo hydrochloric acid soaking and steam explosion to separate carbohydrates, proteins and celluloses in the bean residues and the bagasse, and the proteins and the carbohydrates are decomposed by microbial fermentation to generates polypeptides and polysaccharides with short molecular chains. Ggraphite reacts with potassium permanganate in a sulfuric acid solution to form a graphene oxide material, and the graphene oxide is mixed with the fermented bagasse and soybean residues to make the hydrogen graphene adsorbed through hydrogen bonds, intermolecular forces and other chemical bonding forces; and the graphene oxide has epoxy groups and sulfo groups, so bonding of an external substrate is benefited, thereby the adhesion performance of the matting resin is further improved, and the matting resin has a broad application prospect.

Description

technical field [0001] The invention relates to a preparation method of a highly adhesive matting resin, belonging to the technical field of resins. Background technique [0002] In recent years, water-based matting coatings have been widely demanded, but most of these matting coatings are made by adding matting agents or matting powders. As a water-based matting paint of this preparation method, for example, a method of dispersing a silica matting agent in a self-crosslinking acrylic resin; a water-based one-component matting type clear topcoat in which a matting agent is added to an acrylic-modified polyurethane system Add matting agent to polyacrylic polyol to form component A, and then mix component A and component B anion-modified HDI polyisocyanate in proportion to make a water-based two-component matting clear finish; add matting powder The method is added to water-emulsion type anionic polyurethane resin and water-based acrylic resin to form a finishing agent for ma...
