Abstract
A method for preparing polyvinyl chloride/hydrotalcite nanocomposite resin includes steps of reacting on hydrotalcite with fatty acid or anion surface activator for 0.5-10 hr. at 30-150 deg.C under liquid phase agitating, obtaining modified hdrotalcite through filtering and drying; and adding modified hydrotalcite, initiator, dispersing agent, Vinyl chloride and deionized water into reactor for agitating of 10-60 min. at room temperature and obtaining PVC composite resin by rising temperature to 35-65 deg.C for polymerization and removing unreacted monomer out.
Description
Technical field
The present invention relates to the preparation method of modified PVC resin, relate in particular to the preparation method of a kind of polyvinyl chloride/hydrotalcite nano compound resin.

Polyvinyl chloride (PVC) has characteristics such as comprehensive mechanical property is good, fire-retardant, resistance to chemical attack, and can obtain hard, semi-rigid and flexible article with adding what of plasticizer loading, satisfies different service requirementss.Poor heat stability, hard product shock strength are low, shortcomings such as plasticizer exudation easily take place flexible article but PVC also exists.Wherein poor heat stability mainly causes the PVC dehydrochlorination to cause by heat and other factors in the course of processing, can make goods that undesirable colour-change takes place, and the decline of mechanical property.Therefore, the necessary thermo-stabilizer that adds in PVC processing is as organic acid metal salt, organo-tin compound and alkali formula lead compound.In order to improve the shock strength of hard PVC goods, adopt PVC and organic impact modifier usually, as the method for blend such as chlorinatedpolyethylene, ethylene-vinyl acetate copolymer, acrylate copolymer.In order to reduce the plasticizer exudation of flexible PVC goods, can adopt all or part of replacement small molecules of macromole softening agent softening agent.
Adopt laminated inorganic matter, especially use polynite, compound with polymkeric substance is the main method of preparation polymer nanocomposites.When the montmorillonite-based nano lamella is aggregated that thing is peeled off or during intercalation, the thermotolerance of matrix material, fire-retardant and barrier property are improved significantly, and show the huge advantage of nano modification.But polynite belongs to cationic clay, usually need with ammonium salt cationoid tensio-active agent its intercalation processing that organises, with the rippability that improves polynite in the Composite Preparation process and with the consistency of polymkeric substance.Ammonium salt is thermally-stabilised poor, decomposes easily in the preparation of polymer-montmorillonoid matrix material or the course of processing, causes the material variable color, and this shows more obvious with imvite modified PVC the time.

3+Layer positively charged, interlayer anion goes up the positive charge balance with layer, and integral body presents electric neutrality.
Because natural water talcum impurity is many, reserves are few, so industrial general employing synthetic hydrotalcite.Hydrotalcite synthetic main method is a coprecipitation method, with magnesium salts and the co-precipitation in containing carbonate or other anionic basic solution by a certain percentage of aluminium salt, and carry out crystallization, can obtain different x values or Mg/Al than (x commonly used is 0.33 and 0.25, be that the Mg/Al ratio is 2 and 3), have carbonate or other anionic hydrotalcite (CN1193857, CN1288078).For the hydrotalcite of special anionic, can utilize the anionic commutative characteristic of hydrotalcite layers, replace the negatively charged ion of common hydrotalcite and be prepared with corresponding negatively charged ion.
Because unique texture and character that hydrotalcite had, hydrotalcite can be used as the properties-correcting agent of chemical reaction catalyst, sorbing material and macromolecular material.But utilize interchangeability, interlayer intercalation and the strippable characteristics of nanometer laminate of the interlayer anion of hydrotalcite, lipid acid that available heat has good stability or anion surfactant carry out organic intercalation to hydrotalcite to be handled, obtain the interlayer exchange ion kind modified hydrotalcite different, and prepare the fashionable intercalation of macromolecular material/houghite nano composite material or peel off by in-situ inserted polymerization or blend intercalation with interlamellar spacing.
Adopt hydrotalcite-modified PVC, more existing patent reports both at home and abroad.The characteristics of utilizing the hydrotalcite layers negatively charged ion can consume PVC degradation production hydrogenchloride can be used (CN1114661A, US4427816, day clear 60-184536 of disclosure special permission communique etc.) as the PVC auxiliary heat stabilizer with hydrotalcite.Utilize hydrotalcite hydrotalcite can be used as the PVC fire retardant by losing the characteristics that the hydroxyl dehydration of interlayer planar water and surface institute absorbs heat.In addition, utilize hydrotalcite, can obtain the hydrotalcite-modified PVC goods that weathering resistance is good or have warming characteristic ultraviolet ray, ultrared absorption and energy transformation characteristic.Therefore, hydrotalcite is a kind of good, multi-functional PVC auxiliary agent or properties-correcting agent.
But, present hydrotalcite-modified PVC mainly adopts composite hydrotalcite in the PVC course of processing and carries out the method for melt blending, though can utilize the thermally-stabilised modifying function of hydrotalcite, not utilize hydrotalcite to be peeled off by PVC or the intercalation formation nano effect that nano-dispersed produced to PVC.
