Problems solved by technology

[0006] The main technical problem to be solved by the present invention is to solve the problem that the currently commonly used construction adhesives contain aldehyde organic solvents, which are harmful to the body and pollute the environment, and the bone glue is not water-resistant, loses bonding strength due to water swelling, and is not corrosion-resistant. The problem is to provide a method of using bone glue to prepare green composite building adhesives. The invention pretreats sheep bones to make them fully expanded, and then separates the bone glue by soaking in water and adjusting the pH value. The bone glue and polyethylene Diol and sodium isocyanate are mixed and reacted to finally obtain a composite construction adhesive. The present invention modifies the biological bone glue, and the prepared adhesive is not only environmentally friendly, but will not cause poisonous harm to production and users, and its adhesive Strong joint force, good water resistance, strong corrosion resistance, improve the life of the adhesive

Abstract

The invention discloses a preparation method of environment-friendly green composite building adhesive and belongs to the field of adhesives. Sheep bones are pretreated to be completely puffed, water is added for immersion, the pH value is adjusted, and then bone glue is formed after separation; the bone glue, polyethylene glycol and sodium cyanate are mixed and react, and finally the composite building adhesive is obtained. The biological bone glue is modified, the prepared adhesive is environmentally friendly, free of harm to production and users, high in adhesive force, good in waterproofness and high in corrosion resistance, and the service life of the adhesive is prolonged.
