Description
Technical field
The present invention relates to a kind of preparation method of adhesive, and in particular to a kind of preparation method of Bone glue adhesive.
Background technology
The adhesive dosage in China is still very big at present, therefore function admirable and the adhesive of environmental protection are developed into
Current study hotspot, wherein being modified one of focus of research for already becoming researcher to the gelatine of natural environmental-protective.
Gelatine has a extensive future, but because its freezing point is high, aqueous stability is poor, poor water resistance, adhesion strength are low, glued membrane
The shortcomings of poor toughness, it is set to be limited in the development of every profession and trade.
The content of the invention
The shortcomings that it is an object of the invention to overcome above-mentioned prior art, there is provided a kind of preparation method of Bone glue adhesive,
Bone glue adhesive prepared by this method has the characteristics of adhesion strength is high, freezing point is low, stability is good, has excellent water-resistance.
To reach above-mentioned purpose, the preparation method of Bone glue adhesive of the present invention comprises the following steps：
Gelatine solution is taken, then gelatine solution is added in flask, warming while stirring is to 40 DEG C~80 DEG C, then to flask
Middle addition Al2(SO4)3, potassium rhodanide, methanol and sodium benzoate are added after constant temperature stirring, constant temperature stirring reaction, obtains gelatine gluing
Agent.
The mass ratio of gelatine particle and water is 1.0 in gelatine solution:1.0-2.0.
The quality of gelatine particle is Al in gelatine solution2(SO4)3The 0.4%~4% of quality.
The quality of potassium rhodanide is 10%~25% of gelatine quality in gelatine solution.
The quality of sodium benzoate is 0.4%~2% of gelatine quality in gelatine solution.
Al is added into flask2(SO4)3, potassium rhodanide, methanol and sodium benzoate are added after constant temperature stirring 30-90min.
Constant temperature stirring reaction 30-60miin, obtains Bone glue adhesive.
The ratio of gelatine is 0~0.316 in methanol and gelatine solution：1.
The invention has the advantages that：
The preparation method of Bone glue adhesive of the present invention passes through gelatine molecule during Bone glue adhesive is prepared
In active group amino and carboxyl and Al2(SO4)3In Al3+Complexation reaction occurs for ion, generates the coordination of gelatine-metal
Compound, so as to reach the purpose being modified to gelatine, while gelatine solution is prevented by potassium rhodanide, methanol and sodium benzoate
Freeze, anti-condensation and preservative treatment, obtain Bone glue adhesive, so that Bone glue adhesive keeps liquid condition at low temperature, and then effectively
Make Bone glue adhesive that there is the characteristics of adhesion strength high, high stability and low-freezing, be provided simultaneously with excellent water resistance,
And operational sequence is reduced, and processing cost is relatively low, is easy to promote.
