Summary of the invention
The present invention is in order to overcome deficiency of the prior art, provide a kind of paper grade (stock) to give birth to the preparation method of natural plant gum sizing agent, to give birth to the sizing agent that natural plant gum is the main raw material preparation, overcome with the chemical industrial product is the resource that sizing agent produced of feedstock production and expending and three-waste pollution of energy conversion, and on function, have with fiber and react, constitute the function of covalence key; And can shorten the curing time of applying glue process greatly, obviously improve the WATER RESISTANCE and the paper physical intensity of paper.
The present invention is achieved through the following technical solutions for achieving the above object, and a kind of paper grade (stock) is given birth to the preparation method of natural plant gum sizing agent, and it is characterized in that: concrete steps are as follows,
1. by ratio of weight and the number of copies, gelatin 0.2-0.6, three chloro-, 2 Hydroxyproyl Trimethyl ammonium chloride 0.01-0.06, excess water are added in the emulsifier, stirred 1-2 hour under 60 ℃ of-80 ℃ of temperature, emulsification makes the intermediate A of dissolving to all melting breast;
2. sesbania gum 3-5, guar gum 1-3 are slowly added in the excess water solution in the reactor, transfer PH8-9 with ammoniacal liquor, stirred 20 minutes, add melamine acetaldehyde resin 0.8-2.5, hexa 0.008-0.06 again evenly, with acetic acid adjust pH 3-5, be warming up to 75 ℃-90 ℃, be incubated 0.5-1.5 hour, must be to intermediate B;
3. be cooled to 65 ℃, intermediate A is added in the intermediate B solution, stir the sodium aluminate solution 2-4 that adds 20% concentration after 0.5-1.5 hour, transfer pH3-5 with aluminum sulfate solution, stirred 0.5 hour, cooling discharge can make to give birth to and plant the glue sizing agent.
Beneficial effect: adopt cation high molecular polymer that the reaction of natural plant gum and functionalization auxiliary agent amido macromolecular compound obtains to improve binding ability between sizing agent and applying glue to fibers, the starch three as emulsifying agent, accelerate the slaking speed and the sizing efficiency of paper sizing process, can satisfy the specific (special) requirements of high speed paper machine.Give birth to and to plant glue to execute bright dose be cationic sizing emulsions, micro-positive charge on the paper surface band after the applying glue has improved the ink absorption and the printing of paper.Give birth to the natural plant gum sizing agent, mainly be to meet current environment protection requirement and save a large amount of non-renewable resources and energy resource consumption in the preparation to adopt water to do solvent and reaction medium, and moreover produce the ton sizing agent and utilize renewable raw materials only to be 1/3rd of traditional raw material consumption, with the minimizing of a large amount of height the consumption of raw material, and usefulness also promotes significantly.Can be used for paperboard, corrugated paper and cultural paper also can be used for top grade paper such as art post paperboard, white board.
