Embodiment 1

[0017] Weigh a certain amount of bone glue, and dissolve the weighed bone glue in water, stir evenly to obtain a bone glue solution with a mass concentration of 10%, heat the prepared bone glue solution to 40°C, and then add aluminum sulfate. Stir for 10 minutes under the condition of ~60°C to obtain milky white gelatinous hydrophobic bone glue, wherein the ratio of bone glue to aluminum ion in aluminum sulfate is 1000kg:0.15mol.

Embodiment 2

[0019] Weigh a certain amount of bone glue, and dissolve the weighed bone glue in water, stir evenly to obtain a bone glue solution with a mass concentration of 15%, heat the bone glue solution to 60 degrees, then add aluminum trichloride, and then heat it at 40 to 60 degrees. Stir for 40 minutes under the condition of ℃ to obtain milky white hydrophobic bone glue, wherein the ratio of bone glue to aluminum ion in aluminum trichloride is 1000kg:0.6mol.

Embodiment 3

[0021] Take a certain amount of bone glue, and dissolve the weighed bone glue in water, stir to obtain a bone glue solution with a mass concentration of 20%, and heat the bone glue solution to 40° C., then add tin tetrachloride. Stir for 40 minutes under the condition of 40-60 to obtain milky white hydrophobic bone glue, wherein the ratio of bone glue to tin ions in tin tetrachloride is 1000kg:0.3mol.

Abstract

The invention discloses a preparation method of hydrophobic bone glue. The preparation method comprises the following steps of 1) weighing a certain amount of bone glue, dissolving the bone glue in water, and uniformly stirring to obtain a bone glue solution with the mass concentration of 10%-20%; 2) heating the well prepared bone glue solution to 40-60 DEG C, then adding a metal ion salt which can form a complex, and stirring at constant temperature to obtain milky white hydrophobic bone glue, wherein the proportion of the bone glue to metal ions in the salt is 1000kg: (0.15-0.6mol). According to the preparation method disclosed by the invention, a stable five-membered ring metal complex is formed by amino groups and carboxyl groups in macromolecules of the bone glue and the metal ions, so that hydrophilic groups (carboxyl groups and amino groups) on the bone glue molecules can be successfully removed by reaction, and the water resistance of the bone glue is significantly improved.

Description

technical field [0001] The invention relates to a preparation method of bone glue adhesive, in particular to a preparation method of hydrophobic bone glue. Background technique [0002] Bone glue is a protein derivative obtained by hydrolysis of collagen, which is composed of a variety of different α-amino acids. It has the advantages of high bonding strength, low price, biodegradability, and no pollution. It used to be a widely used wood adhesive. Because it is a protein adhesive, it has strong hydrophilicity, which greatly reduces its application performance and limits its application market. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a method for preparing hydrophobic bone glue. The hydrophobic bone glue prepared by the preparation method has strong hydrophobicity. [0004] In order to achieve the above object, the preparation method of the hydrophobic bone gl...
