摘要
采用转相法制备了系列阴离子型石蜡/腰果酚醛树脂乳液,并考察了其与氧化淀粉共混液的表面施胶性能。结果表明,在该研究的乳化条件下,m(石蜡)∶m(石蜡/腰果酚醛树脂)=8∶2～6∶4的混合物能形成稳定的乳液,其胶粒粒径为400～630 nm;氧化淀粉与石蜡/腰果酚醛树脂乳液共混液的表面施胶大幅提高了箱板纸的疏水性和环压强度,乳液中腰果酚醛树脂的质量分数越大,乳液的表面施胶作用效果越大,但共混液提高纸页拉伸强度的作用效果不及氧化淀粉。
The anionic emulsions of paraffin wax and method. Surface sizing performance of the mixtures of showed that the mixtures of paraffin wax and paraffin cardanol formaldehyde resin were prepared by phase inversion oxidized starch and those emulsions was investigated. The results wax/cardanol formaldehyde resin with mass ratio of 8 ： 2-6 ： 4 could form stable emulsions under the emulsification conditions studied, in which the size of colloids was from 400 nm to 630 nm. With surface sizing by the mixtures of oxidized starch and paraffin wax/cardanol formaldehyde resin emulsion, hydrophobic property and ring crush strength of cardboard was improved significantly. The greater the mass ratio of the resin in the emulsion, the greater the surface sizing effect of the mixtures. But the improvement of cardboard tensile strength by the mixtures was less than that by the oxidized starch.
