Firstly, we should prepare polyester glycol in order to prepare water-borne polyurethane emulsion used to wooden furniture. Polyester glycols having designed molecular weight of 1000 are synthesized by ethylene glycol and mixture of phthalic anhydride and adipic acid (morl radio =40:60)on condition that molar excess content of glycol is 15%, and high vacuum time is 8h.The produced polyester glycols having the same molecular weight as designed measure up to standard of material. And Water-borne polyurethane emulsion's hardness is better than others are produced by aliphatic polyester glycol.
