Abstract
The invention relates to a low temperature hot melting adhesive. According to the technical scheme, the low temperature hot melting adhesive comprises, by weight, a polyolefin and acrylic acid copolymer, a Fischer Tropsch wax, a tackifying resin and an antioxidant; and the preparation process comprises: (1) heating a reaction kettle, adding a Fischer Tropsch wax into the reaction kettle, and melting; (2) after melting the Fischer Tropsch wax, stirring at a uniform speed, slowly adding a polyolefin and acrylic acid copolymer during the stirring, and melting; (3) after the polyolefin and acrylic acid copolymer is added and completely melts, increasing the temperature of the reaction kettle while stirring, slowly adding a tackifying resin, and melting; (4) after completely melting the tackifying resin, adding an antioxidant, and uniformly stirring; and (5) transferring the uniformly-stirred material into a cooling kettle. The low temperature hot melting adhesive of the present invention can be used for food packaging with requirements of low use temperature and rapid curing, and soap packaging, toothpaste packaging, beverage bottle packaging and other small packaging.
Description
Technical field:
The present invention relates to tackiness agent, particularly a kind of Environment-friendlylow-temperature low-temperature hot melt adhesive of bonding when being widely used in paper made package box joint sealing.
Background technology:
The hot melt adhesive of present packing case joint sealing is with ethene-vinyl acetate for main material, paraffin as lubricant, resin as the compound of tackifier.Because the use temperature of this hot melt adhesive is at 160 DEG C ~ 175 DEG C, and cannot bond for the carton that surface is covered with plastic film, and easily brittle under cryogenic, easily cause phenomenon of coming unglued.
Summary of the invention:
The object of this invention is to provide a kind ofly facilitate low temp operation, bond the low-temperature hot melt adhesive that fast, not easily comes unglued.
Technical scheme of the present invention completes as follows, it includes following composition by weight, polyolefine and acrylic acid multipolymer 20-50 part, take and drag wax 10-30 part, tackifying resin 20-50 part, oxidation inhibitor 0.5-2 part, its preparation technology is: in still, add expense when 1. first reactor being warming up to 130 DEG C and drag wax, melted; 2. after expense drags wax to melt, start agitator at the uniform velocity to stir with 40 revs/min, in stirring, slowly add polyolefine and acrylic copolymer, make it melt; 3. when multipolymer adds and after melting completely, promote temperature of reaction kettle, adjust mixing speed is 60 revs/min simultaneously, when temperature in the kettle rises to 160 DEG C, more slowly adds tackifying resin and makes it melt; 4. after tackifying resin melts completely, add oxidation inhibitor again, stir; 5. the above-mentioned material stirred is transferred in cooling reactor, package spare after cooling.
Product of the present invention can be different according to the different choice of purposes compound proportion, it not only solves the easy embrittlement of EVA hot melt adhesive service requirements temperature high and low temperature cannot be covered with the defect of the carton goods of film by gluing of surfaces, but also can be used to the small-sized packaging such as food product pack and perfumed soap, toothpaste, beverage bottle that packing instructions use temperature is low, curing speed is fast.
Embodiment:
The present invention has following examples: embodiment one, get out following material: polyolefine and acrylic copolymer 37 kilograms, softening temperature are that 110 DEG C of expenses drag 22 kilograms, wax, tackifying resin 41 kilograms, 0.5 kilogram, oxidation inhibitor; Operate by following technique again: 1. first reactor is warming up to 130 DEG C, then drag wax to still Nei Jiafei, make it melt; 2. start after expense drags wax to melt and stir, at the uniform velocity stir with 40 revs/min, under whipped state, slowly add polyolefine and acrylic copolymer, treat that it melts; 3. when multipolymer adds and after melting completely, promoting temperature of reaction kettle, to adjust mixing speed be 60 revs/min simultaneously, when temperature in the kettle rises to 160 DEG C, more slowly add tackifying resin and make it melt; 4. after tackifying resin melts completely, add oxidation inhibitor again, stir; 5. the above-mentioned material stirred is transferred in cooling reactor, package spare after cooling.This product is mainly applicable to domestic automatic sealing package box assembly line and uses.
Embodiment two: each proportioning raw materials is as follows: polyolefine and acrylic copolymer 30 kilograms, softening temperature are that the expense of 110 DEG C drags 28 kilograms, wax, tackifying resin 42 kilograms, 0.5 kilogram, oxidation inhibitor; Its preparation method is with embodiment one, and the tag adhesive that the product that it is produced is mainly used in quick Labelling Machine uses.
Embodiment three: each proportioning raw materials is as follows: polyolefine and acrylic copolymer 48 kilograms, softening temperature are that the expense of 110 DEG C drags 20 kilograms, wax, tackifying resin 32 kilograms, 0.5 kilogram, oxidation inhibitor; Its preparation method is with embodiment one, two, and the product that it is produced is mainly used in the small-sized packaging box provided of kraft paper food pack and perfumed soap, toothpaste.
