Abstract

The invention discloses a cigarette polypropylene fiber filter rod forming solid adhesive which is prepared from the following raw materials in parts by weight: 1-2 parts of divinyl benzene, 4-6 parts of epoxy butyl oleate, 60-70 parts of microcrystalline paraffin, 10-14 parts of powdery butyronitrile, 2-3 parts of 2-mercaptobenzothiazole, 10-15 parts of sisal fiber, 0.8-2 parts of sp-80, 0.3-0.4 part of a nitric acid solution with the concentration of 10-12 mol/l, 200-210 parts of ethylene-ethyl acrylate copolymer, 1.3-2 parts of zirconium oxychloride, 0.5-1 part of lactic acid and 0.6-1 part of glycerin. According to the invention, by using lactic acid/glycerol organic zirconium, which has an obvious temperature-sensitive cross-linking characteristic, as a cross-linking agent, and ethylene-ethyl acrylate copolymer fiber base fluid as a thickening agent, and through cross-linking action, gel with good temperature resistance and shearing resistance can be formed. Since fiber-treated copolymer base fluid is adopted, the surface activity of the copolymer is improved, a cross-linking effect is promoted and viscoelasticity and thixotropy are improved.

(3) joined by zirconium oxychloride in 2-3 times of water, stirring and dissolving, adds lactic acid, glycerol, and regulation system pH value, to 4-5, is uniformly mixed 4-5 hour, obtains organic zirconium crosslinker;

(4) joined in 3-4 times of dehydrated alcohol by 2-thiol group benzimidazolyl, stirring and dissolving, obtains oxidation resistance liquid;

(5) by copolymer fibre base fluid, organic zirconium crosslinker mixing, in the constant temperature oil bath of 80-90 DEG C, stir 20-30 minute, period drips above-mentioned oxidation resistance liquid, dropwises rear discharging cooling, obtains organic zirconium gel;

(6) mix with residue each raw material by organic zirconium gel, raised temperature is 170-180 DEG C, insulated and stirred 2-3 hour, cools, cuts off shaping, centrifugally to dry, to obtain final product through tank.

Advantage of the present invention is:

The present invention with lactic acid/glycerol organic zirconium for linking agent, it has obvious temperature sensitive crosslinking feature, with ethylene-ethyl acrylate copolymer fiber base fluid for viscosifying agent, pass through crosslinked action, the gel with good temperature and shearing sustainability can be formed, adopt the multipolymer base fluid of fiber treatment, multipolymer surfactivity can be improved, promote cross-linking effect, improve visco-elasticity and thixotropy.

Adhesive storage stability of the present invention is good, being conducive to the quality improving mouth rod, after heat fused, spraying with calming the anger, and makes polypropylene fiber ambient cure become rod.
