Abstract
The invention relates to a process for preparing cationic rosin size. The process comprises the following specific steps: respectively adding acrylamide and cation into a reaction kettle, introducing nitrogen, and enabling the acrylamide to react with cation to prepare a dispersing agent; adding a certain amount of rosin into a mixing tank, adding the dispersing agent into the mixing tank, embedding the mixing tank into sand as deep as possible, enabling the rosin to react with the dispersing agent in the mixing tank to form rosin size in a mode of dripping the dispersing agent; taking the mixing tank out of the sand after the rosin and the dispersing agent in the mixing tank completely react, the mixing tank is cooled to be below 100 DEG C, and the rosin size is in an emulsion shape, and taking out the rosin size in the mixing tank. The process has the advantages that the sand serves as a heating medium and is slow in heat dissipation. Therefore, in the whole process, the heating frequency of the sand is low, the energy is saved, the sand which drops due to a certain reason is timely and easily cleaned, and equipment is not needed to be sealed.
Description
Technical field
The present invention relates to a kind of cation colophony glue preparation technology.
Background technology
As everyone knows, at present pulping internal sizing is still take gum rosin as main, and is all better than Dispersed Anionic Rosin Size and soap glue with its performance of cation colophony glue, effect, technical economic benefit in gum rosin; Can self keep on fiber as cation colophony glue, sizing material and addition of aluminum sulfate significantly reduce; PH is at 4.5-5.5 for the applying glue of anion glue, and CATION glue applying glue pH carries out in the nearly neutrality of 4.7-6.5, few to the corrosion of paper machine, can extend paper machine life-span 30-50%; Plain boiled water is near neutral and clean, improves whitewater closure rate, reduces water and consumes and can reach 50%; CATION glue to water hardness require do not have anion soap glue and dispersion agent strict; The pitch trouble that can reduce summer applying glue difficulty and cause because of impurity more; Can improve degree of sizing and physical strength and resistance to ag(e)ing etc. of paper product.It can bring obvious technical economic benefit to paper plant the above-mentioned various advantages of cation colophony glue.But CATION glue amount is few and valency is high in the market, and this hangs back many factories.Current, the report of researching and developing CATION glue is both at home and abroad a lot, its objective is and reduces costs, and increases the benefit and simplifies using method etc.
At present, in the prior art, in the process of production gum rosin, what great majority adopted is that conduction oil heats.But, in the process of heat-conducting oil heating, find several shortcomings adopting: while using heat-conducting oil heating, occur to leak once conduction oil, can be to environment around, and be relatively difficult to cleaning; When overheated, can there is cracking, coking or carbon distribution in container, pipeline; In the time that heating-up temperature exceedes 70 ℃, contact meeting with air and be strongly oxidized, therefore also need a set of water-tight equipment, increase cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cation colophony glue preparation technology easily that consumes energy less, clears up.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of cation colophony glue preparation technology, and its innovative point is: described step is specially:
A) first, in reactor, add respectively acrylamide and CATION and pass into nitrogen, utilizing acrylamide and cationoid reaction to make dispersant;
B) by dark as far as possible stirred tank being embedded in sand, the temperature of sand is more than 135 °, and the temperature of reactor is controlled at 130 ° of left and right, and a certain amount of rosin is placed in to stirred tank, adds the dispersant making in step a in stirred tank simultaneously;
C) dispersant adopts the mode dripping to add in stirred tank, in the process dripping, before dropping, the rotating speed of stirred tank is 400r/min, and in the process dripping, the rotating speed of stirred tank is increased to suddenly 1800r/min by original 400r/min, the speed dripping is 6ml/min, after dropping finishes, the rotating speed of stirred tank is down to again 400r/min, and in stirred tank, rosin reacts with dispersant and forms gum rosin;
D) after rosin in stirred tank and dispersant react completely, treat that stirred tank is cooled to below 100 ℃, after gum rosin is emulsion form, stirred tank can be taken out from sand, the gum rosin in stirred tank is taken out simultaneously.
The invention has the advantages that: utilize sand as heat medium, the heat radiation of sand is slow, therefore in whole process, few to the heating times of sand, save the energy; Even if sand is unrestrained because of certain reason, in cleaning, ratio is easier to; Gather even if sand is exposed to air, also can not react with oxygen, therefore do not need water-tight equipment, saved cost.
The specific embodiment
The preparation method of cation colophony glue of the present invention, is mainly achieved by following step.
The first step first, adds respectively a certain amount of acrylamide and CATION and passes into nitrogen in reactor, utilizes reaction between acrylamide and CATION to make dispersant.
Second step, is placed in stirred tank by a certain amount of rosin, adds the dispersant making in the first step in stirred tank simultaneously, and by dark as far as possible stirred tank being embedded in sand, the temperature of sand is more than 135 °, and the temperature of reactor is controlled at 130 ° of left and right.
The 3rd step, dispersant adopts the mode dripping to add in stirred tank, in the process dripping, before dropping, the rotating speed of stirred tank is 400r/min, in the process dripping, the rotating speed of stirred tank is increased to suddenly 1800r/min by original 400r/min, and the speed of dropping is 6ml/min, after dropping finishes, the rotating speed of stirred tank is down to again 400r/min, and in stirred tank, rosin reacts with dispersant and forms gum rosin.
The 4th step, after rosin in stirred tank and dispersant react completely, treats that stirred tank is cooled to below 100 ℃, after gum rosin is emulsion form, stirred tank can be taken out from sand, the gum rosin in stirred tank is taken out simultaneously.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
