Abstract:
　 In conventional process of preparing soy based wood adhesive, the dosage of alkali is often high-er than 6%～ 7%(w /w)of the dry soy flour mass, adding on about 4%of lime milk. T he alkalinity hy-drolysis of soy protein caused by the residual alkali is always loss control and it is considered as the mainreason of low water tolerance of soy based wood adhesive. In present investigation , a novel two stepwiseprocess was adapted. Firstly half dosage of denaturants combined with low liquor ratio was used to createa high concentration circumstance tha was necessary for soy globulin unfolding ;and in the second step, thelion share of water was mixed with the denatured soy flour that quickly dilute the alkali to keep the stabili-ty of unfolded soy protein. Water tolerable soy based wood adhesive was successfully manufactured by thisnovel processing art.
