Description

A kind of cigarette special adhesive

Technical field

The present invention relates to chemical field, relate in particular to a kind of cigarette special adhesive.

Background technology

Polyvinyl acetate emulsion, the common name milky white adhesive has cheap, series of advantages such as production is easy, easy to use, excellent performance, non-toxic and safe, non-environmental-pollution, is widely used in the bonding of porous materials such as paper, wad, timber.At present, the milky white adhesive that the most of cigar mills of China use is a polyvinyl acetate emulsion, and protective colloid is a Z 150PH.Such colloid is not anti-to be frozen, and winter, very easy frozen glue breakdown of emulsion was used for high-speed cigarette machine, and disrepair phenomenons such as alice, rake angle can appear in cigarette.

Summary of the invention

The present invention has overcome deficiency of the prior art, and a kind of cigarette special adhesive is provided, and is applicable to that the cigarette machine of domestic existing different model is done the cigarette glue use, also can be used as the high performance universal milky white adhesive.

In order to realize above-mentioned purpose, adopt following technical scheme:

A kind of cigarette special adhesive, its component and weight part are:

Vinyl acetate between to for plastic 40-50

Z 150PH 6-8

Witcizer 300 2-3

Linking agent Me-10 5-8

Catalyst for copolymerization Zh-4 0.3-0.5

Water surplus.

Cigarette special adhesive provided by the invention, be by Vinyl Acetate Monomer with water tail dispersion medium, Z 150PH is emulsifying agent and protective colloid, under catalyst for copolymerization, carry out letex polymerization after, add linking agent and do agent and process.

Vinyl acetate between to for plastic has another name called vinyl acetate, vinyl acetate, for colourless flammable liquid, overpowering odor is arranged, and is water insoluble, is dissolved in most of organic solvents, can with other monomer polymerizations.In this special adhesive effective constituent.

Linking agent Me-10 is the water white transparency thick liquid, and is water-soluble, is insoluble to common organic solvents.In this special adhesive, be used as emulsion modifying agent.

Catalyst for copolymerization Zh-4 is white crystal or powder, and is soluble in water, is prone to moisture absorption and lumps, and is heated and then decomposes.In this special adhesive, be used as the Vinyl Acetate Monomer catalyst for copolymerization, it is fast to have a polymerization rate, and free monomer is few, can reduce characteristics such as emulsion film forming temperature.

The manufacture craft of said special adhesive is following:

S1 adds entry and Z 150PH in dissolving vessel, under constantly stirring, be warming up to 88-92 ℃, keeps this temperature to Z 150PH all to dissolve;

S2 adds 1/3 of vinyl acetate between to for plastic total amount in reactor drum, stir;

S3 is warming up to 80 ℃ with reactor drum, stirs 1-2 hour, and then adds catalyst for copolymerization Zh-4, remaining vinyl acetate between to for plastic and Z 150PH, and temperature of reaction remains on 80-85 ℃, and reaction is warming up to 90 ℃ after finishing, and continues reaction 10-30 minute;

S4 constantly stirs and is cooled to 60-70 ℃, adds linking agent Me-10, fully stirs 30 minutes;

When S5 treats that temperature is reduced to 50-60 ℃, add Witcizer 300, stir postcooling, filter the back packing to room temperature.

Cigarette special adhesive provided by the invention has characteristics such as water-fastly, heat-resisting, anti-freeze, initial adhesive strength is good.The cigarette machine that is applicable to domestic existing different model is done the cigarette glue use, also can be used as the high performance universal milky white adhesive.

Embodiment

Below in conjunction with embodiment the present invention is done further description.

In dissolving vessel, add 35.5g water and 6g Z 150PH, under constantly stirring, be warming up to 88 ℃, keep this temperature to Z 150PH all to dissolve.In reactor drum, add the 15g vinyl acetate between to for plastic, stir.Reactor drum is warming up to 80 ℃, stirred 1.5 hours, and then the polyvinyl alcohol solution that adds 0.5g catalyst for copolymerization Zh-4,30g vinyl acetate between to for plastic and prepare, temperature of reaction remains on 80 ℃, and reaction is warming up to 90 ℃ after finishing, and continues reaction 20 minutes.Constantly stir and be cooled to 60 ℃, add 10g linking agent Me-10, fully stirred 30 minutes.When treating that temperature is reduced to 50 ℃, add the 3g Witcizer 300, stir postcooling, filter the back packing to room temperature.

This cigarette special adhesive finished product outward appearance is the oyster white glue, and solids content is 40%-50%, and the pH value is 5-7.During use emulsion poured in the emulsion hopper of cigarette machine and get final product.

Claims (1)
