Preparation and properties of environmental friendly wood adhesives based on wild acorn starch

摘要：

　　A friendly environmental wood adhesive was prepared using wild acorn starch as a raw material.The physical properties of wild acorn starch were investigated by scanning electron microscope (SEM) and brookfield viscometer.The polyvinyl acetate emulsion and isocyanate were employed to prepared modified wild acom starch adhesives.The plywoods were prepared using the adhesives and their bonding strength was measured.The experimental results showed that 1) the wild corn starch was adaptive for preparing adhesive; 2)the optimum preparing conditions of the modified wild acorn starch adhesive were as follows:the mass ratio of acorn starch/water/modifing agent was 8/9/3,the addition amount of viscosity reducer was 0.6%,the mass proportion of polyvinyl acetate emulsion/starch adhesive was 1/1,the addition amount of isocyanate was 15% weight of starch adhesive.The plywood using the adhesive prepared at the optimum condition was 0.9 MPa,could meet the type Ⅱ Chinese Strandard plywood requirement.
