Abstract

The invention discloses a preparation method of environmentally friendly building adhesive. The method comprises the steps that 1), gum acacia and shell lac are poured into an agitating pan, heating agitation processing is conducted under the condition of compression to obtain viscous liquid; 2), terpene resin, glycerol ester of rosin, turpentine, aluminium silicate powder, white carbon black andthe like are poured into an agitation tank to perform agitation processing to obtain a mixture; 3), emulsion obtained in step 2) is poured into the viscous liquid obtained in step 1), agitation is constantly performed until the material is cooled down to room temperature, ethanol is added, and emulsifying agitation processing is conducted to obtain the adhesive. According to the method, the residual formaldehyde content of the environmentally friendly building adhesive is extremely low, the health of human is not affected, which is beneficial to the protection of the environment.

Description
