Summary of the invention
The object of the invention is, for the more weak problem of existing WATER RESISTANCE monomer reactivity, to provide a kind of Cypres improving cardboard WATER RESISTANCE.
The present invention is achieved by the following technical solutions: a kind of Cypres improving cardboard WATER RESISTANCE, comprise the component of following weight portion: hydroxypropyl cellulose 15-20 part, medical stone 2-6 part, cationic etherifying agent 0.5-1.5 part, alkyl ketene dimer 12-18 part, sodium bicarbonate 0.06-0.08 part, initator 0.02-0.04 part, viscosity stabiliser 0.4-1.4 part, deionized water 65-70 part.
As further improvement of these options, described initator is one or both combination solvents of acrylate solvent or vinyl acetate solvent, and solvent strength is 20-25wt%.
As further improvement of these options, described viscosity stabiliser is the diethylene glycol solution of 2 ethyl hexanoic acid potassium, and solution density is 1.09-1.13g/mL.
As further improvement of these options, its preparation method is as follows:
(1) add hydroxypropyl cellulose in deionized water, medical stone and alkyl ketene dimer mix in proportion in inert gas, add cationic etherifying agent, sodium bicarbonate and initator, make it react, and obtain CATION jelly;
(2) in CATION jelly, add viscosity stabiliser mixing, add NaOH simultaneously and solution pH value is adjusted to 7-9, reaction;
(3) by gained solution after reaction in step (2), add deionized water, after water-solubleization, heat up in a steamer organic compound, the Cypres of the cardboard WATER RESISTANCE that is improved.
As further improvement of these options, step reacts 4-6 hour in (1) in 30-50 DEG C.
As further improvement of these options, in step (2), after jelly cooling in step (1), in 55-65 DEG C, react 1-2 hour, then cool to 25-35 DEG C.
The present invention has the following advantages compared to existing technology: by modified for hydroxypropyl cellulose simplification production technology, improve the activity of water resistant monomer, thus reduce the consumption of hydroxypropyl cellulose, reduce production cost, gained Cypres WATER RESISTANCE improves, and stability is better, strengthens paper pull, sizing efficiency is high, and economic benefit is obvious.
