摘要: 以生物油、淀粉为主要原料制备绿色环保、价格低廉的生物油-淀粉胶黏剂(BOSA)并用于室内胶合板的制备。以淀粉乳液浓度、丙烯酰胺、过硫酸铵及生物油加入量作为试验因子,以胶黏剂的胶合强度、固含量和黏度作为评价指标,采用正交试验法优选出合成BOSA的最佳合成工艺。结表表明:当淀粉乳液质量分数为40%、丙烯酰胺为20%、过硫酸铵为2.5%、生物油为20%时,胶黏剂的综合性能最好,储存期达到15 d,胶合板胶合强度(1.44 MPa)达到国家标准GB/T 9846—2004中Ⅲ类胶合板(≥0.7 MPa)要求。

Abstract: Bio-oil, and starch were used as the main material for preparing environmental friendly and low price bio-oil starch adhesive(BOSA)which was applied in the preparation of interior plywood. Influence of the starch emulsion concentration, acrylamide content, ammonium sulfate and bio-oil content on the bonding strength, solid content and viscosity of BOSA were investigated, and the optimal preparation conditions were determined by orthogonal experiments. The results showed that the BOSA had best combination property, its bonding strength(1.44 MPa)could reach the national standard GB/T 9846—2004 of class Ⅲ plywood(≥0.7 MPa)requirement, and the storage life reached 15 days when mass fractions of the concentration of starch emulsion was 40%, ammonium sulfate content was 2.5%, acrylamide and bio-oil content were 20%.
