Preparation method of bone glue adhesive

Abstract

The invention discloses a preparation method of a bone glue adhesive. The preparation method comprises steps as follows: a bone glue solution is taken, added to a flask and heated to the temperature of 40-80 DEG C while being stirred, then Al2(SO4)3 is added to the flask, potassium thiocyanate, methanol and sodium benzoate are added after constant-temperature stirring, the mixture is stirred at a constant temperature to have a reaction , and the bone glue adhesive is obtained. The bone glue adhesive prepared with the method has the characteristics of high adhesion strength, low solidifying point, good stability and excellent water resistance.

Description

Technical field [0001] The invention relates to a method for preparing an adhesive, in particular to a method for preparing a bone glue adhesive. Background technique [0002] At present, the amount of adhesives in our country is still very large, so the development of adhesives with excellent performance and environmental protection has become a current research hotspot, among which the modification of natural and environmentally friendly bone glue has become one of the research hotspots of researchers. Bone glue has a broad application prospect, but its development in various industries is limited due to its high freezing point, poor aqueous solution stability, poor water resistance, low bonding strength, and poor film toughness. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a method for preparing a bone glue adhesive. The bone glue adhesive prepared by the method has the charac...
