Abstract

The thermosol is made up by using natural bee wax and paraffin wax as base material and adding vaseline, grease and rosin and making them pass through such processes of heating and uniformly mixing. A proper amount of dry-resisting agent can also be added. The main raw materials are natural matter which are non-toxic, odorless and according to the requirements of law on Food Hygiene. It is suitable for packing of cigarette and food industries. The working temp. is lower by 30 deg.C than the thermo sol using EVA as main body, the consumption can decrease by 40% and the allowance of viscosity is less than 1%.

Description

Thermosol for cigarette, food stuff packing

The present invention relates to a kind of tackiness agent, specifically a kind of food, cigarette package hot melt adhesive

Existing food, cigarette package hot melt adhesive are to be the main body base-material with the EVA resin, are aided with that paraffin and anti-aging agent form again.The use temperature of this hot melt adhesive is higher to be more than 120 ℃, the viscosity height, and consumption is big; And imitate short set time, and it is unfavorable that this seals mechanical type, and the shelf-time is also short, about about 1 year.Chinese patent CN 1044674A discloses a kind of caking agent that is used for cigarette filter, processed by polyvinyl acetate (PVA) second alcohol and water: CN1073193A discloses a kind of bactericidal adhesive goods that can be used for food etc., these goods are with dissolving in lsothiocyanates basically or can form tackiness agent by the polymkeric substance of its swelling, forming binder layer.CN 1050208A discloses the used hot melt adhesive of a kind of adhesive tape, mainly by binder resin, tackifying resin, antiblocking agent and solvent composition.

The purpose of this invention is to provide a kind of is the body material hot melt adhesive with the crude substance.This product is nonpoisonous and tasteless, is fit to cigarette and foodstuffs industry packing and uses.

The present invention is achieved in that mainly to stir with natural wax, Vaseline, animal grease and rosin heating and melting and forms, and also can add an amount of silicone oil for prolonging the shelf-time.

The weight percent of each component is:

Beeswax 30～60%

Paraffin 8～25%

Vaseline 3～10%

Rosin 20～50%

Animal grease 1～5%

After if the hot melt adhesive of said components is made, directly use then need not add silicone oil; If need long-term storage to use after for some time, then can add an amount of silicone oil.

Processing of the present invention mainly is that each component is uniformly dispersed, and also promptly mixes to want fully can to use single stage method, promptly takes by weighing various materials in proportion, stirs after dropping into the fusion of same container internal heating, gets product.Also can say, can earlier beeswax, paraffin and Vaseline heating be mixed, make work in-process with two steps.Then again work in-process, rosin, animal grease and silicone oil are together heated and mix, be finished product.

Product body material of the present invention is crude substance, and is nonpoisonous and tasteless, meets the food hygiene law requirement, it is 30 ℃ of the hot melt adhesives of main body base-material that working temperature is lower than with the EVA resin, and amount ratio is that the hot melt adhesive of main body base-material is few with the EVA resin, can preserve under viscosity tolerance≤1%, normal temperature 2 years.Be applicable to the packing of cigarette and foodstuffs industry

Embodiments of the invention are described below:

To process 1000 gram hot melt adhesives is example:

One, get beeswax 300 grams, paraffin 120 grams, Vaseline 40 grams, rosin 500 grams, animal grease 40 grams, heating and melting stirs and promptly gets product in still, can be directly used on the packaging production line.If must deposit then with water cooling just condensation be block.For making the product long-term storage, can before cooling off, add and cool off again after 2～5 gram silicone oil stir.

Two, get beeswax 300 grams and the common heating of paraffin 250 grams, in addition with Vaseline 80 gram heating and meltings, mix then and stirred 30 minutes, and be warming up to 90 ℃ simultaneously, kept 2 hours, use filter cleaning again, make work in-process.

Again work in-process, rosin 320 grams and animal grease 50 grams are added reactor, be heated to 100 ℃, stir after 15 minutes, add an amount of silicone oil and mix, get product.Can also cool off finished product with cold water, make it become bulk.

Three, get beeswax 600 grams, paraffin 80 grams, Vaseline 30 grams, rosin 250 grams, animal grease 40 grams and silicone oil are an amount of, and its working method is with embodiment one or two.

Four, get beeswax 450 grams, paraffin 150 grams, Vaseline 50 grams, rosin 330 grams, animal grease 20 grams and silicone oil are an amount of, and its working method is with embodiment one or two.
