Problems solved by technology

The mouthpiece glue produced by this method can meet the demand of 12,000-17,000 cigarettes per minute, and the residual amount of vinyl acetate monomer has also been correspondingly reduced. The content is still high, which cannot meet the production needs of up to 20,000 pieces / minute, and the emulsifier OP-10 used in the synthesis process is an alkylphenol polyoxyethylene ether nonionic emulsifier, which has accumulated damage to the human body

Embodiment 1

[0063] 1. Ratio preparation

[0064] Prepare materials according to the following proportions by weight: 60 parts of vinyl acetate, 14 parts of acrylic acid, 7 parts of methyl methacrylate, 12 parts of polyvinyl alcohol, 0.6 part of ammonium persulfate, 156 parts of deionized water, 5 parts of triethyl citrate 0.5-0.8 parts of polydimethylsiloxane, 1.5 parts of polyoxyethylene lauryl ether, 0.5-0.8 parts of Bropol, and 1.4 parts of sodium bicarbonate.

[0065] In an embodiment of the present invention, ammonium persulfate can also use other thermal decomposition initiators, such as potassium persulfate, tert-butyl hydroperoxide, and a redox system initiator, such as ammonium sulfate-bisulfite Sodium, etc.; Triethyl citrate can also be replaced by acetyl tributyl citrate, triacetin or 2,2,4-trimethyl-1,3-pentanediol diisobutyrate; Base siloxane can also be replaced by white mineral oil, but polydimethylsiloxane is preferred; Bropol used in the present invention can also be rep...

Embodiment 2

[0085] In addition to preparing materials according to the following proportions by weight: use 64 parts of vinyl acetate, 12 parts of acrylic acid, 7 parts of methyl methacrylate, 0.6 parts of ammonium persulfate, 1.6 parts of sodium bicarbonate, 14 parts of polyvinyl alcohol, isomeric alcohol poly 1.4 parts of oxyethylene ether, 5 parts of triethyl citrate, 0.6 parts of polydimethylsiloxane, 0.6 parts of Bropol, 193 parts of water; and the remaining 18 parts of polyvinyl alcohol aqueous solution in the reactor, other Steps and mode of operation are all the same as in Example 1.

Embodiment 3

[0087] In addition to preparing materials according to the following proportions by weight: use 62 parts of vinyl acetate, 16 parts of acrylic acid, 8 parts of methyl methacrylate, 0.8 parts of potassium persulfate, 1.5 parts of sodium bicarbonate, 10 parts of polyvinyl alcohol, lauryl polyoxygen 1.5 parts of vinyl ether, 4 parts of triethyl citrate, 0.6 part of white mineral oil, 0.6 part of isothiazolinone, 180 parts of total water; Example 1 is the same.

Abstract

The invention discloses a water-based ultra-high-speed spraying filter tipping adhesive and a preparation method thereof. The method uses polyvinyl alcohol as a protective colloid, and isomeric alcohol polyoxyethylene ether as an emulsifier to produce a ternary copolymer emulsion of vinyl acetate, methyl methacrylate, and acrylic acid, further improves fluidity and cohesiveness by adding a plasticizer and a polyvinyl alcohol aqueous solution, effectively lowers residual vinyl acetate monomers by vacuuming while stirring under relatively high temperature, and uses ionized water to adjust viscosity, thereby producing the ultra-high-speed spraying filter tipping adhesive suitable for a spraying gluing cigarette making machine. The method does not use any alkylphenol ethoxylates emulsifier which has accumulative harm to human body; and on the premises of low viscosity and low solid content, the produced filter tipping adhesive has high paper adhesion and high drying speed, and can achievestable adhesive supply on the spraying gluing cigarette making machine which is working at a speed of 20000 cigarettes per minute. The produced cigarette does not show air leak, filter tipping disconnection, wrinkles, or other undesirable phenomena, and has low a rejection rate.

Description

technical field [0001] The invention relates to a polymer adhesive, in particular to a water-based super-high-speed spray nozzle glue suitable for the cigarette industry. Background technique [0002] Mouth glue is an important cigarette material connecting cigarettes and filters, and its consumption is the largest among all water-based cigarette glues including lap glue for cigarettes, packaging glue and filter rod forming centerline glue. In the cigarette production process, it plays a decisive role in the crimping quality of cigarettes. At present, the gluing methods of the nozzle glue mainly include roller coating and spraying gluing. Different gluing methods have different performance requirements for the nozzle glue. One is that at the same coiling speed, compared with the roller coating method, spraying glue requires a more suitable drying speed of glue. Second, different gluing methods require different rheological properties of the nozzle glue. In order to prevent...
