Abstract
The invention relates to a method for preparing waterproof adhesive for corrugated paper production, and belongs to the technical field of paper coating adhesive. A starch-isopropenyl acetate cross linked graft copolymer is synthesized, and then the waterproof adhesive for the corrugated paper production is prepared. The method for preparing the waterproof adhesive for the corrugated paper production can effectively reduce the damage of water molecules to the adhesive so that the waterproof property of the adhesive is greatly improved; and because the hydrophilic property of the modified adhesive declines, the adhesive has good quick drying property and is favorable to be used on high-speed corrugated lines.
Description
Technical field
The present invention relates to a kind of preparation method of anti-glue stick of Corrugated Box production usefulness, belong to paper coating adhesive technical field.
Background technology
Can engage by the mode of glue paste between the surface of variant production in the prior art, on technical scale, the typical surface that is bonded together by the glue paste mode comprises paper surface and paperboard surface.In this respect, the glue paste mixture of starch preparation since its preparation simply, its technical characterstic and acceptable economically manufacturing cost thereof be widely used.But the shortcoming that has the water resisting property difference in actual use, the corrugated cardboard of production are easily got damp and are felt like jelly and cause the cohesive strength, side pressure strength of cardboard to descend.
Chinese invention patent CN200310105824.7, a kind of preparation method of fast-drying type corn starch adhesive agent is disclosed, this method is selected novel catalyst Fe 2+ for use, the consumption that has reduced oxygenant is to 5% of dry starch quality, shorten the reaction times to the 30min, made a kind of cheapness and the Starch Adhesive of high bond strength.The modified alta-mud of adding dry starch quality 30% or sodium bentonite have improved rate of drying greatly as filler before adding the NaOH gelatinization.It is not high that this invents described tackiness agent water resisting property, and rate of drying is relatively slow when using.
Summary of the invention
The present invention solves the deficiencies in the prior art, a kind of anti-water glue paste of the fluting board production usefulness that forms by crosslinking reaction is provided, make the wetting ability of anti-water glue paste descend, anti-simultaneously water glue paste has quick-drying characteristic, helps using on watt line at a high speed.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of preparation method of anti-glue stick of fluting board production usefulness comprises following processing step:
1), synthetic starch-isopropenyl acetate cross-connect graft copolymer:
With starch is raw material, with acetic acid is catalyzer, with the ammonium persulphate is initiator, with the isopropenyl acetate is monomer, under acidic conditions, carry out graft copolymerization, in the graft copolymerization again with N, the N-methylene-bisacrylamide is a linking agent, carries out crosslinking reaction and synthetic starch-isopropenyl acetate cross-connect graft copolymer;
2), the anti-glue stick of preparation fluting board production usefulness:
The starch that step 1) obtains-isopropenyl acetate cross-connect graft copolymer carries out crosslinking reaction with the borax for the secondary crosslinking agent under alkaline condition, the product after the gelatinization adds the defoamer tributyl phosphate and mixes, and obtains the anti-glue stick of fluting board production usefulness.
As preferably, described step 1) synthetic starch-isopropenyl acetate cross-connect graft copolymer is: be raw material with starch, after being mixed with mass percentage concentration and being 40～50% starch emulsion, with acetic acid is catalyzer, with the ammonium persulphate is initiator, in the pH value is 3～5 scope, slowly drip the isopropenyl acetate monomer that adds starch quality 85～95%, carry out graft copolymerization, the graft copolymerization temperature is 60～80 ℃, the graft copolymerization time is 4～6 hours, at graft copolymerization after 2 hours, add starch quality 0.2～0.5%, mass concentration is that 1～2% acrylamide carries out crosslinking reaction as linking agent, and reinforced and reaction is all under agitation carried out, and reaction product is starch-isopropenyl acetate cross-connect graft copolymer.(to the consumption of catalyzer and initiator preferably as a matter of expediency in or illustrate in the specification sheets)
As preferably, described step 2) be main raw material with starch-isopropenyl acetate cross-connect graft copolymer in, add the caustic soda of starch quality 40～60% and the borax of starch quality 1～2%, carry out crosslinking reaction at 50～60 ℃, the tributyl phosphate that product after the gelatinization adds starch quality 2～5% mixes, obtain Corrugated Box production with anti-glue stick, reinforced and mix and all under agitation carry out.
Therefore, the preparation method of the anti-glue stick of a kind of fluting board production usefulness provided by the invention, can effectively reduce the destruction of water molecules to tackiness agent, make the water resisting property of tackiness agent improve a lot, because wetting ability degradation after the tackiness agent modification, make to have good fast dry characteristic, thereby help using on watt line at a high speed.
