Abstract

The invention discloses a kind of hot fusible adhesive for package, belong to adhesive field.In terms of mass fraction, prepares raw material and include at least:35 parts of EVA resin, 30 ~ 50 parts of tackifying resin, 10 ~ 20 parts of viscosity modifier, 0.5 ~ 1.5 part of antioxidant;The present invention hot fusible adhesive for package have it is environment-protecting and non-poisonous, without heavy metal, curing rate is fast, resistance to low temperature is excellent, to higher facial tissue intensity(Carton facial tissue pulls out wax degree and reaches 20A or more)The advantages that adhesion strength of carton is high solves the problems, such as that traditional EVA hot-melt adhesive occurs when the carton for coping with higher facial tissue intensity bonds on line and warehouse is unpacked, can be widely applied to the automatic packaging industry of the industries such as food, beverage, beer.

Description

A kind of hot fusible adhesive for package
Technical field
The invention patent relates to adhesive field, especially a kind of hot fusible adhesive for package.
Background technology
In packaging industries such as food, beverage, beer, often there is outer packing damage by carrying, after storage process in product Seriously, brand names image is influenced.Some esbablished corporations are in order to ensure that Product transport keeps good outer packing to point-of-sale terminal Effect constantly upgrades packaging material, promotes carton intensity, improves waterproof effect etc., however is imitated to bonding for hot melt adhesive Fruit requires also be continuously improved with curing rate.
Since cost is relatively low, technology maturation is widely used always traditional EVA hot-melt adhesive.But in packaging upgrade of material Afterwards, traditional EVA hot-melt adhesive can no longer meet the bonding requirements of plastics on new materials, reaches particularly with carton facial tissue peel strength and pulls out After wax degree 18A or more, appearance bonding is insecure, and warehouse is unpacked serious.Processing enterprise has to select of high cost 1 ~ 1.5 ten thousand/ton Polyolefin hot-melt substituted.
For supplier, processing profit itself is very thin, and selects material also without right of speech, hot melt adhesive cost Greatly improve, a undoubtedly no small spending.Therefore for a large amount of brand foundry processing enterprises, a moderate cost, Good to plastics on new materials adhesive effect, the exploitation of the hot melt adhesive of stable quality becomes extremely important and urgent.
Invention content
For the above-mentioned market status, the present invention provides a kind of fast package hot melt adhesive, technical solution is:
A kind of hot fusible adhesive for package is made of the raw material of following mass fraction:
Body material Ratio
EVA thermoplastic resins 35 parts
Tackifying resin 30 ~ 50 parts
Viscosity modifier 10 ~ 20 parts
Antioxidant 0.5 ~ 1.5 part
The EVA thermoplastic resins include at least VA contents 28%, EVA the and VA contents 40% of MI 400 ~ 800, MI 40 ~ 100 Two kinds of EVA or two or more.
The tackifying resin includes at least the C9 resins of 110 ~ 120 DEG C of softening point, the rosin glycerine of 90 ~ 100 DEG C of softening point Fat, 100 ~ 110 DEG C of pentaerythritol resin two or more.
The viscosity modifier includes at least 95 ~ 105 Fischer-Tropsch wax of softening point, and PE synthetic waxs are a kind of or a kind of in microwax More than.
The antioxidant includes at least the one or more in 1010,2112,168.
The preparation method of the hot fusible adhesive for package, including following procedure:
(1)According to mass fraction by EVA, viscosity modifier is added in reaction kettle, is heated to 160 DEG C to the state that melts, and stir It mixes uniformly;
(2)140 DEG C are cooled to, tackifying resin, antioxidant, insulated and stirred 30min are added according to mass fraction;
(3)10min is vacuumized, is squeezed out by double screw extruder, it is cooling, it is granulated, is packaged into finished product.
The present invention can obtain following technique effect as a result of preceding solution:
(1)The type and ratio of preferred EVA, tackifying resin and modified waxes further improve the compatibility of each component, brittleness temperature Degree decline 10 ~ 15 DEG C, to avoid at low temperature bonding interface be stressed and embrittlement occur, be obviously improved to high intensity material Low temperature bonding performance.
(2)The increase of the EVA proper ratios of preferred VA contents 40%, reduces the shrinking percentage of rising again of hot melt adhesive, is coping with When high intensity facial tissue bonds, bonding is more secured after rising again.
(3)Preferred viscosity modifier type and adding proportion, improve the compatibility of each component, colloid crystallization rate, And the wetting effect after hot melt adhesive melting is improved, help to promote hot melt adhesive lower temperature resistance, curing rate and to material Infiltration and wetability.
The melt viscosity knotting strength that the present invention produces is big, and brittleness temperature is low, and curing rate is fast, and shrinking percentage of rising again is low, makes With wide temperature range, it is very suitable for high-intensity carton(Facial tissue is A grades of kraft inner papers or K grades of kraft inner papers)Quick joint sealing use.
