Description
Technical field
The present invention relates to field of papermaking, specifically a kind of special paper grade (stock) butadiene-styrene latex and preparation method thereof.
Background technology
Adhesive used in papermaking is sizing agent. Applying glue is the important step in paper-making process, it can give the liquid-repellency energy that paper product is certain, and increase its intensity, Process of Applying Glue is to utilize hydrophobic substance to be covered in paper fiber surface to form one layer of hydrophobic film, reduce fiber surface free energy, thus stoping water or other liquid in the diffusion of fiber surface, moistening or infiltration. Applying glue has two kinds of methods, and one is before sheet formation, makes an addition in paper pulp by sizing agent, be called plasm-glue-blending when making beating or dispensing; Another kind is to cover with paint, lacquer, colour wash, etc. to be called top sizing in its surface after sheet formation. Sizing agent is generally with hydrophilic group and hydrophobic group, and hydrophilic group is combined with electronegative fiber directly or indirectly, and hydrophobic group is then outside paper, and the hydrophobic group of paper makes paper product be provided with liquid-repellency. By the difference of Principle of neutral sizing, sizing agent can be divided into anionic sizing agent, cationic size and non-ionic sizing agent, cellulose, hemicellulose in paper product are electronegative, anionic sizing agent can not directly be combined with fiber, can only be combined with fiber by cationic substance, such as anionic rosin sizing agent, the bridging action mainly by Monomer is combined with fiber indirectly. Cationic size is positively charged, can with fiber directly in conjunction with, for instance cationic starch Cypres. Non-ionic sizing agent itself is without electric charge, but by being combined the lotus that becomes positively charged with cationic substance, then is combined with cellulose. Except toilet paper, blotting paper, cigarette paper etc. require absorbability, good paper does not need applying glue, and the paper of overwhelming majority kind needs the applying glue carried out in various degree. Now, paper industry has played many changes: the use of a large amount of secondary stocks and non-wood pulp, and printing technology equipment is growing, and the surface property of paper is had higher requirement; The paper product of difference in functionality needs the sizing agent of different performance. Environmental regulation is gradually improved, it is desirable to paper industry reduces, eliminates and pollute.
Traditional paper adhesive mainly has gelatin, starch, polyvinyl alcohol adhesive and polyvinyl acetate emulsion etc. Wherein gelatin, starch adhesive owing to adhesive strength is low, storage period short do not use substantially; The maximum shortcoming of polyvinyl alcohol adhesive is exactly poor water resistance, and paper tube compressive resistance increases with the resting period and significantly declines, and improves although can obtain part after acetalation, but still can not meet requirement.
