Problems solved by technology

[0004] The technical problem mainly solved by the present invention: Aiming at the present situation that currently commonly used adhesives are mostly chemically synthesized, which contain more formaldehyde, pollute the environment, and endanger human health, a preparation method of creeper sucker polysaccharide bio-adhesive is provided, In this method, the ivy sucker is used as the raw material to be cleaned and crushed, and then degreased by ethanol reflux, and then hot water is used to extract the degreased sucker, the extract is concentrated and centrifuged to obtain the sucker polysaccharide, and then the polysaccharide and dehydrated egg white are mixed with a catalyst, and the water bath Heating reaction finally produced a creeper sucker polysaccharide bioadhesive

Abstract

The invention relates to a preparation method for a parthenocissus tricuspidata sucker polysaccharide biological adhesive, and belongs to the field of preparation of biological adhesives. The method comprises the following steps of washing and crushing parthenocissus tricuspidata suckers serving as a raw material, performing ethanol refluxing to realize degreasing, extracting the degreased suckers with hot water, concentrating extract, performing centrifugation to obtain sucker polysaccharides, mixing the polysaccharides and dehydrated egg white, adding a catalyst, and performing water bath heating reaction to finally obtain the parthenocissus tricuspidata sucker polysaccharide biological adhesive. According to the method, byproducts also have high utilization value, egg yolks can be used as a food processing raw material, and eggshells can be used as calcium-rich food or an additive for animal feeds; the preparation method also has the advantages of simple production process, no pollution in a production process, low reaction temperature, short reaction time, no environmental pollution and the like.

Description

technical field [0001] The invention relates to a method for preparing a creeper sucker polysaccharide bioadhesive, and belongs to the field of bioadhesive preparation. Background technique [0002] Ivy, also known as Gossypium genus, is a deciduous climbing plant of the Vitaceae family. Due to its luxuriant branches and leaves, most of them are used as greening plants. The branches have stretched tendrils or suckers. When encountering obstacles, such as rocks, Walls or trees, etc., can be attached to it. The reason is that there are suckers on the top of its tendrils, which can secrete a viscous liquid, so it can climb on the surface of rocks, walls or trees and other substrates. The viscous liquid secreted by the ivy sucker is the sucker polysaccharide. [0003] The adhesive used for bonding wooden boards in the existing decoration industry has a lot of formaldehyde content, which seriously pollutes the living room and causes great harm to human health. In recent years, ...
