Abstract
The invention discloses the preparation method of a high ring crush strength corrugated base paper, firstly, a starch is added into the corrugated paper slurry then stirred to be even; secondly, a non-ionic epoxy resin is added; finally, a polyacrylamide is added and stirred to be even, then making the high ring crush strength corrugated base paper is carried out. Because the invention uses a component whose structure and characteristic are different from a ring crush strength intensifier present widely used, the component comprises a plurality of benzene rings and epoxy groups. The benzene rings can endow the ring crush strength intensifier with very high glass transition temperature, and then enhances the ring crush strength of the corrugated base paper; at the same time, the cross linking function of the epoxy groups can make a powerful covalent bond combination exist between the paper fiber, which makes the corrugated base paper have certain wet strength.
Description
Technical field
The invention belongs to papermaking chemical product preparation technology field, particularly a kind of preparation method of high ring-pressure strength corrugated base paper.
Background technology
Fluting medium is the important source material paper that is used to make corrugated case, and it mainly acts on is to bear under the situation of strain when corrugated case, the boxboard on two sides can be separated, so that cardboard keeps maximum thickness, thereby makes cardboard obtain maximum moment of inertia.Therefore, ring crush intensity is the most important quality requirement of fluting medium.At present, domesticly be used to produce the employed ring pressure strengthening agent of fluting medium and mainly contain starch based, polyacrylamide, copolymer emulsion type reinforcing agent and shitosan class reinforcing agent.But the effect of these ring pressure strengthening agents is undesirable, causes prepared corrugated paper products class not high.
Summary of the invention
The object of the present invention is to provide a kind of preparation technology simple, and can obviously improve the preparation method of the high ring-pressure strength corrugated base paper of ring crush intensity.
For achieving the above object, the technical solution used in the present invention is: at first add starch and stir in corrugation paper pulp, add nonionic epoxy resin then, add the polyacrylamide high ring-pressure strength corrugated base paper of can manufacturing paper with pulp that stirs at last, wherein the mass ratio of corrugation paper pulp, starch, nonionic epoxy resin and polyacrylamide is 100: 0.01-5: 0.01-5: 0.01-0.3.
Corrugation paper pulp of the present invention comprises and does not float chemical pulp, semi-chemical pulp or OCC secondary stock; Starch comprises ative starch, cationic starch or oxidized starch; Nonionic epoxy resin is meant that water-soluble bisphenol A type epoxy resin or particle radii are the water and milk bisphenol A type epoxy resin of 20nm-2 μ m; Polyacrylamide employing number average relative molecular mass is 500,000-2,000 ten thousand cationic polyacrylamide, non-ionic polyacrylamide or anionic polyacrylamide.
The present invention uses is a kind of component that all is different from the ring pressure strengthening agent that extensively adopts at present on structure and the characteristic, is made up of a large amount of benzene ring structures and epoxide group.Benzene ring structure can give the ring pressure strengthening agent very high glass transition temperature, and then obviously improves the ring crush intensity of fluting medium; Simultaneously, the crosslinked action of epoxide group can make and have strong covalent bonds between the paper fiber, makes fluting medium have certain wet strength.When the present invention is applied to quantitatively be the fluting medium of 220g/m2, compare with blank sample, ring crush intensity can improve more than 60%, even can reach 240%, and wet strength can improve more than 10%.
