Abstract
The invention discloses a water-base gravure ink copolymer emulsion and a binder, allyloxy hydroxypropy sulfonate sodium aqueous solution is added into a mixed solution containing monomers, hydrophilic monomers, molecular weight regulator and ammonium persulfate of carboxyl and carboxyl functional group for preparing the emulsion by copolymerization , alkaline solution is then neutralized and alcohol solubilizing assistant is added to obtain water-base gravure ink copolymer emulsion and the binder. On the one hand, the water-base gravure ink copolymer emulsion and binder save a large amount offood, one the other hand, the water-base gravure ink copolymer emulsion and binder save reduce the use of organic solvents, thereby effectively avoiding the defects that the organic solvent is inevit ably combustible and explosive, pollutes environment and jeopardizes health of production worker, and the environment-friendly requirements of the binder are met. The material is widely applied to tipping paper, has viscosity of 90-150 seconds and strong water absorptivity and slow-release function, and can keep the tipping paper from water absorption and deformation and meet the demands of the production of cigarette filter tip.
Description
Technical field
The present invention relates to a kind of glue paste, relate in particular to the caking agent of a kind of cigarette filter, belong to the adhesive techniques field with yew paper.
Background technology
The ethanol-soluble type cigarette is chewed the paper glue is chewed paper yew paper gravure printing ink as cigarette connection material; Its principle is the character of utilizing Vinyl Acetate Copolymer to be soluble in to contain in the ethanol of portion water; Introduce Bing Xisuandingzhi plasticising, methylacrylic acid hydrotropy through emulsion copolymerization simultaneously; Produced pure dissolubility cigarette under the multiple factor effect of polyoxyethylene nonylphenol solubilising and chewed the connection material of paper (yew paper) gravure printing ink, connection material per ton consumes about 600 kilograms of 95% edible ethanols, and when preparation printing ink, also will use a large amount of ethanol; Though this kind solvent is nontoxic, but still belong to volatile organic matter and so on.The early 1990s in last century; In order to save a large amount of practical ethanol, begin the no ethanol caking agent of development, like Chinese invention patent application CN90109256.8; A kind of " adhesive for water soluble coating used for cigarette tipping paper " disclosed; Adopt sodium alginate, tripoly phosphate sodium STPP, sodium oleate, urea, styrene-butadiene latex, formaldehyde, water and skimmer to mix by a certain percentage,, adopted the materials such as formaldehyde that do not meet environmental requirement now though a large amount of practical ethanol has been practiced thrift in the use of this tackiness agent; On the basis that cigarettes are hazardous to health; Increased carcinogenic substance again, long-term contact can the serious harm direct labor and smoker's health, in the use that has been under an embargo of many countries.Along with modern society strengthens environmental protection and awareness of safety day by day; In recent years for reduce or without organic solvent, energy-saving and cost-reducing, reduce in topsoil, the printing office clean environment and avoid fire hazard, the researchist is at research and development yew adhesive for paper of new generation both at home and abroad.
Summary of the invention
Usually the water-soluble copolymer resins of preparation has two kinds of methods: comonomer is copolymerized into thick shape copolymer resins in organic solvent; Carry out alkaline hydrolysis then and make water-soluble copolymer resins; Also have comonomer to add in forming to contain carboxylic monomer in organic solvent, to be copolymerized into acid thick shape copolymer resins, add in the amine and obtain water-soluble with salify.
The objective of the invention is to overcome the deficiency of prior art; Providing monomer that a kind of employing contains carboxyl and hydroxy functional group and hydrophilic monomer to be used molecular weight regulator carries out emulsion copolymerization and processes after the emulsion ammonia neutralization bases again and dissolve; Add the alcohols hydrotropy again, be prepared into the new type water-solubility thermosetting adhesive, save a large amount of grain on the one hand; Reduce with an organic solvent on the other hand, make tackiness agent meet environmental protection requirement.
Realize that technical scheme of the present invention is achieved in that
Water-base gravure ink copolymer emulsion is characterized in that: the mixed solution copolymerization by adding the monomer, hydrophilic monomer, molecular weight regulator and the ammonium persulfate aqueous solution that contain carboxyl and hydroxy functional group in the allyloxy hydroxypropyl azochlorosulfonate acid sodium aqueous solution reflux course forms.
Said hydrophilic monomer has any two kinds mixture in vinyl acetate, ethyl propenoate, methyl acrylate and the uncle's capric acid vinyl acetate.
The said monomer that contains carboxyl functional group is a kind of in vinylformic acid, methylacrylic acid, MALEIC ANHYDRIDE and the methylene-succinic acid.
The monomer of said hydroxy functional groups is a kind of in Hydroxyethyl acrylate, Propylene glycol monoacrylate, Rocryl 400 and the Rocryl 410.
Said molecular weight regulator is a kind of in dodecyl mercaptans, trichloromethane and the Virahol.
Composition in the above-mentioned emulsion is allyloxy hydroxypropyl azochlorosulfonate acid sodium 0.45-0.55 gram, vinyl acetate 65-75 gram, uncle's capric acid vinyl acetate 8-12 gram, methylene-succinic acid 8-12 gram, Hydroxyethyl acrylate 8-12 gram, dodecyl mercaptans 0.08-0.12 gram, ammonium persulphate 0.25-0.35 gram and water 120 grams.
Mix by above-mentioned emulsion 200-220 gram and zero(ppm) water 180 grams that the back adds organic amines or ammoniacal liquor transfers to 8-9 with pH value, add 95% edible ethanol 130-170 gram then and mix hydrotropy and form water-base gravure ink and connect and expect.
The present invention compared with prior art has following advantage:
1. be prepared into the new type water-solubility thermosetting adhesive; Save a large amount of grain on the one hand; Reduce on the other hand with an organic solvent, avoided effectively that organic solvent type institute is inevitably inflammable and explosive, shortcomings such as contaminate environment and harm direct labor health, make tackiness agent meet environmental protection requirement.
2. cigarette filter stick there are 2 basic demands with caking agent, the one, the viscosity of caking agent must be enough low, to satisfy the needs of mouth rod high-speed production lines; The 2nd, guarantee that the yew paper that wraps up the mouth rod does not produce a wrinkle distortion; Because mouth rod water-absorbent very thin with yew paper and that tool is very strong is easy to suction and sends out the wrinkle distortion; And connection material of the present invention, viscosity is 90-150 second, strong absorptive that has and slow-release function; The distortion that do not absorb water of yew paper can be guaranteed, the requirement that the mouth rod is produced can be satisfied.
