Abstract
The invention discloses a preparation method for a sizing curing time-free alkyl ketene dimer (AKD) neutral/basic sizing agent, which comprises the following steps of: firstly, degrading cassava starch under the action of fungal alpha-amylase; performing cationization on the degraded cassava starch by using 3-chloro-2-hydroxypropyltrimethyl ammonium chloride under the action of sodium hydroxide; then, neutralizing by acetic acid to obtain cation cassava starch solution; performing graft copolymerization reaction between the cation cassava starch solution and acrylonitrile, methyl acrylate, octadecyl methacrylate, methacrylic acid as well as hydroxyethyl acrylate to obtain a copolymer, wherein the copolymer per se is the sizing agent with excellent performance, and the copolymer is used as an emulsifying agent; and emulsifying AKD and beewax by the copolymer to obtain the sizing curing time-free AKD neutral/basic sizing agent. The prepared neutral/basic sizing agent is low in emulsion viscosity and is high in stability. As emulsion particles carry with positive charges and negative charges and molecules contain semi-crosslinking groups, the prepared neutral/basic sizing agent is favorable of retention and can be tightly combined with paper fibers with the negative charges, and therefore, the sizing performance is improved, and the phenomenon that curing time exists in AKD sizing is eliminated.
Description
Technical field
The invention belongs to polymer chemistry sizing agent technical field, particularly a kind of without in applying glue maturation period AKD/preparation method of alkaline sizing agent.
Background technology
The major progress of modern applying glue technology be in/popularization of alkaline bleach liquor sizing technology, during acid papermaking is converted into/alkaline paper-making is the great change in world's papermaking history.In/alkaline bleach liquor sizing is in papermaking process, pH value is adjusted to more than 7, in principle without a kind of glue applying method of aluminum sulfate.In conventional/alkaline sizing agent alkyl ketene dimer (being called for short AKD) is the product of phase late 1940s research and development, AKD be a kind of can with the response type of fibrin reaction in/alkaline sizing agent, it can be as internal sizing agent, again can be as Cypres.Its design feature is to consist of active group and hydrophobic grouping, the fusing point of AKD is lower, active group quaternary lactonic ring energy under the hot conditions of Dryer Section of Paper Machine in molecule and the hydroxyl reaction on cellulose form beta-keto ester bond and are positioned on fiber, and hydrophobic group chain alkyl produces water resistant effect at fiber surface.By in AKD/alkaline bleach liquor sizing, the one way retention of Paper White Degree, feel, WATER RESISTANCE, physical strength, printability, resistance to ag(e)ing and filler etc. is all significantly improved.And can to adopt cheap powdered whiting be filler, reduced the content of harmful substance in plain boiled water, improved the cyclic utilization rate of plain boiled water, AKD is lower than the cost of acid accumulator size simultaneously.Adopt AKD carry out in/alkaline bleach liquor sizing can improve paper product quality and price, reduction energy consumption, improve environmental pollution and paper machine operation performance etc., therefore can obtain obvious economic benefit and social benefit, increasing papermaking enterprise is recognized superiority and the necessity of use in AKD/alkaline sizing agent.China's paper making raw material be take straw pulp as main, timber resource shortage, and secondary stock consumption increases, in utilization/alkaline bleach liquor sizing technology has realistic meaning.Follow in AKD/alkaline bleach liquor sizing technology progressively expands in China's Application Areas, technology is increasingly mature, in/benefit of alkaline paper-making progressively embodied, accelerated paper industry by acid papermaking in/trend that alkaline paper-making changes, in recent years AKD become domestic paper plant use at most, the most ripe, the most effectively in/alkaline sizing agent.
In AKD/alkaline bleach liquor sizing gives paper some excellent properties, also has its weak point simultaneously.AKD can continue to carry out with reacting of paper fibre within a certain period of time, and AKD applying glue not yet completes after page is dry, after batching, is still carrying out, and in 24 hours, in some weeks even thereafter, is also carrying out.Prolongation along with the resting period, the degree of sizing of page can rise, and under paper roll, machine just can reach best sizing efficiency after a period of time, therefore with AKD applying glue, has certain maturation period, within the maturation period, be prone to the phenomenon that sizing efficiency goes down, and the strength character of sized paper decreases.Improve in recent years and to improve the research of AKD emulsion property increasingly active, shorten or eliminate the AKD applying glue maturation period, the AKD emulsion that time is short and sizability is stable that development and production arrives best sizing efficiency is the problem that China's papermaking researcher is made great efforts research always.
Summary of the invention
