Description
技术领域technical field
本发明属于造纸化学品制备工艺领域，特别涉及一种高环压强度瓦楞原纸的制备方法。The invention belongs to the field of preparation technology of papermaking chemicals, in particular to a method for preparing corrugated base paper with high ring crush strength.
背景技术Background technique
瓦楞原纸是用于制作瓦楞纸箱的重要原料纸，其主要作用是当瓦楞纸箱承受应变的情况下，能将两面的箱纸板分开，以使纸板保持最大的厚度，从而使纸板得到最大的惯性力矩。因此，环压强度是瓦楞原纸最重要的质量要求。目前，国内用于生产瓦楞原纸所使用的环压增强剂主要有淀粉类、聚丙烯酰胺类、共聚乳液型增强剂及壳聚糖类增强剂。但这些环压增强剂的应用效果不理想，致使所制备的瓦楞纸制品档次不高。Corrugated base paper is an important raw material for making corrugated boxes. Its main function is to separate the cardboard on both sides when the corrugated box is subjected to strain, so that the cardboard can maintain the maximum thickness, so that the cardboard can get the maximum moment of inertia. . Therefore, ring crush strength is the most important quality requirement for corrugated base paper. At present, the ring pressure strengthening agents used in the production of corrugated base paper in China mainly include starch, polyacrylamide, copolymer emulsion type strengthening agent and chitosan type strengthening agent. However, the application effects of these ring pressure strengthening agents are not ideal, resulting in low-grade corrugated paper products.
发明内容Contents of the invention
本发明的目的在于提供一种制备工艺简单，且能够明显提高环压强度的高环压强度瓦楞原纸的制备方法。The purpose of the present invention is to provide a preparation method of high ring crush strength corrugated base paper which has simple preparation process and can obviously improve the ring crush strength.
为达到上述目的，本发明采用的技术方案是：首先在瓦楞纸浆中添加淀粉搅拌均匀，然后加入非离子环氧树脂，最后加入聚丙烯酰胺搅拌均匀即可进行抄造高环压强度瓦楞原纸，其中瓦楞纸浆、淀粉、非离子环氧树脂和聚丙烯酰胺的质量比为100∶0.01-5∶0.01-5∶0.01-0.3。In order to achieve the above object, the technical solution adopted by the present invention is: firstly add starch to the corrugated pulp and stir evenly, then add non-ionic epoxy resin, and finally add polyacrylamide and stir evenly to make high ring compressive strength corrugated base paper, wherein The mass ratio of corrugated pulp, starch, non-ionic epoxy resin and polyacrylamide is 100:0.01-5:0.01-5:0.01-0.3.
本发明的瓦楞纸浆包括未漂化学纸浆、半化学浆或OCC废纸浆；淀粉包括原淀粉、阳离子淀粉或氧化淀粉；非离子环氧树脂是指水溶性双酚A型环氧树脂或粒子半径为20nm-2μm的水乳性双酚A型环氧树脂；聚丙烯酰胺采用数均相对分子质量为50万-2000万的阳离子聚丙烯酰胺、非离子聚丙烯酰胺或阴离子聚丙烯酰胺。Corrugated pulp of the present invention comprises unbleached chemical pulp, semichemical pulp or OCC waste paper pulp; Starch comprises native starch, cationic starch or oxidized starch; Nonionic epoxy resin refers to water-soluble bisphenol A type epoxy resin or particle radius is 20nm-2μm water-emulsion bisphenol A type epoxy resin; polyacrylamide adopts cationic polyacrylamide, nonionic polyacrylamide or anionic polyacrylamide with number average relative molecular mass of 500,000-20 million.
本发明使用的是一种从结构和特性上都不同于目前广泛采用的环压增强剂的组分，是由大量苯环结构和环氧基团组成。苯环结构能够赋予环压增强剂很高的玻璃化转变温度，进而明显提高瓦楞原纸的环压强度；同时，环氧基团的交联作用可使纸纤维之间存在强有力的共价键结合，使得瓦楞原纸具有一定的湿强度。本发明应用于定量为220g/m2的瓦楞原纸时，与空白试样相比，环压强度可提高60％以上，甚至可达到240％，而湿强度可提高10％以上。The present invention uses a component that is different from the ring pressure intensifier widely used at present in terms of structure and characteristics, and is composed of a large number of benzene ring structures and epoxy groups. The benzene ring structure can endow the ring pressure reinforcing agent with a high glass transition temperature, thereby significantly improving the ring pressure strength of the corrugated base paper; at the same time, the cross-linking effect of the epoxy group can make strong covalent bonds exist between the paper fibers Combined, the corrugated base paper has a certain wet strength. When the present invention is applied to corrugated base paper with a basis weight of 220g/m2, compared with the blank sample, the ring compressive strength can be increased by more than 60%, even up to 240%, and the wet strength can be increased by more than 10%.
