Abstract
The invention relates to a modified polyacetate cotton-spraying adhesive. The modified polyacetate cotton-spraying adhesive comprises a resin component, a polymerization and cross-linking component and an emulsification additive component, wherein the resin component is constituted by vinyl acetate, acrylic acid, methyl methacrylate and butyl acrylate, the polymerization and cross-linking component comprises N-methylol acrylamide and ammonium persulfate, the emulsification additive component comprises sodium dodecyl sulfate, sodium dodecylbenzenesulfonate, OS-15 and sodium hydrogen sulfite, and a carrier component adopts deionized water. An emulsion polymerization process and an oxidation-reduction catalytic system are adopted in the synthesis process, a small amount of water, a cross-linking agent and monomers are firstly added, and by regulating the adding order of the monomers, water resistance, elasticity and softness of the cotton-spraying adhesive are improved.
Description
Art:
The present invention relates to a kind of modification and gather acetic ester spray celloidin, specifically refer to the binding agent being used for when gum sprayed cotton manufactures, fiber being played to cohesive action, belong to field of adhesive technology.
Background technology:
Gum sprayed cotton has been widely applied to the every aspect of people's life, and articles for use are to insulation garment etc. from the bed, does not leave the figure that it exists nowhere.But when same gum sprayed cotton is applied to different field, the requirement of its quality especially pliability is differed widely, be such as applied to insulation garment as filling cotton-wool, it be exactly soft as much as possible for it to be required.Whether the softness of gum sprayed cotton, and the resin structure as the spray celloidin of fiber caking agent is crucial, uses the spray celloidin that hard resin manufactures, and comes in any case also can not do soft gum sprayed cotton.
Summary of the invention:
The present invention discloses a kind of modification and gathers acetic ester spray celloidin, with soft poly-acetic ester for main structure resin, coordinates fiber species to select, and makes the gum sprayed cotton made i.e. tool elasticity but also has good soft feel.
The technical solution used in the present invention is: modification gathers acetic ester spray celloidin and is made up of resin components, polymerization crosslinking component, emulsifying additive component, resin Composition is made up of vinyl acetate, vinylformic acid, methyl methacrylate, butyl acrylate, polymerization crosslinking component is made up of N hydroxymethyl acrylamide, ammonium persulphate, emulsifying additive component is made up of sodium lauryl sulphate, Sodium dodecylbenzene sulfonate, 0S-15, sodium bisulfite, and carrier component adopts deionized water.
Building-up process adopts emulsion polymerization technique and redox-catalyst system, with first adding a small amount of water, linking agent and monomer, and adds order by what regulate monomer, improves the performances such as water-fast, the elasticity of spraying celloidin.
The invention has the beneficial effects as follows: the selection coordinating fiber species, the gum sprayed cotton adopting the spray celloidin of this technology to make, possesses good soft feel while possessing favorable elasticity.
Embodiment:
By weight percentage, the vinyl acetate 77% of resin Composition, vinylformic acid 2.5%, methyl methacrylate 15.3%, butyl acrylate 5.2%; The N hydroxymethyl acrylamide 84.6% of polymerization crosslinking component, ammonium persulphate 15.4%; The sodium lauryl sulphate 11.11% of emulsification, binder component, Sodium dodecylbenzene sulfonate 37.04%, OS-15 is 37.04%; The sodium bisulfite of other additives is 0.1% of total component.Total ingredient proportion adopts resin Composition 40%, carrier component 60%, and emulsification, binder component are by 1.35% of total amount, and polymerization crosslinking component is by 1.3% of total amount.
During concrete enforcement synthesis, first by deionized water, OS-15 and part sodium bisulfite, the mixed solution of ammonium persulphate, the mixed solution of the vinyl acetate of 1/4th and other resin monomers, drop in reactor, adding appropriate Sodium phosphate dibasic adjust ph is about 6, when being slowly warmed up to 65 DEG C, insulation reaction for some time, after making polymeric solution form nucleome, start to drip remaining 3/4ths resin monomer mixed solutions, and drip sodium bisulfite continuously, the mixing solutions of ammonium persulphate, resin monomer mixed solution and sodium bisulfite is synchronously added at 2-3h, the mixing solutions of ammonium persulphate, then 75 DEG C are warmed up to, insulation reaction 1h, be warmed up to 80 DEG C again, insulation 30min, then less than 50 DEG C are cooled to, adjust pH is 6 ~ 7.
