Wooden pencil with one kind of high-performance environment-friendly water-based adhesive and method of preparation

Wooden pencil with one kind of high-performance environment-friendly water-based adhesives, ethylene - vinyl acetate copolymer emulsion 70 ~ 90w%, ethylene - vinyl acetate emulsion Carboxylated 5 ~ 10w% acrylic PSA emulsion and 5 ~ 20w% formula composition. The preparation steps of: feeding ethylene in the reactor - an ethylene vinyl acetate copolymer emulsion, and - the dispersion after stirring Carboxylated vinyl acetate emulsion, and then adjusting the pH of the emulsion blend 8 ~ 10w% of NaHCO3 solution is 6.5 ~ after continued stirring dispersing 7.5; acrylic PSA emulsion is then added, adjusted in viscosity with 3 ~ 5w% solution of polyethylene glycol 1500 ~ 2000mPa.s (23 ℃), dispersed uniformly stirred with 200 to 400 mesh after filtration package. The present invention has good flowability, film speed, good water resistance and aging resistance, adhesion between the bond strength characteristics, is applied to the wood and wooden pencil pencil, wood and wood, it can also be used in PVC the bond between the plastic film.
