Abstract
The present invention discloses high speed water resistant metal label glue and a preparation method thereof. By weight percentage, 3% to 10% of polyvinyl alcohol is taken, and 20% to 40% of water is added to the polyvinyl alcohol. The mixture is stirred for about 40 min in a heat preservation mode in a water bath at the temperature of more than 95 DEG C and is cooled, 12% to 20% of urea and 25% to 30% of water are added to the mixture, and temperature is kept within 60 DEG C to 80 DEG C. Then, 0 to 16% of casein, 2% to 8% of corn starch, 0.4% to 1.6% of zinc sulfate and 0.2% to 0.8% of sodium carbonate are added to the mixture to be stirred for about 120 min in a heat preservation mode. After temperature is lowered below 45 DEG C, 2% to 10% of wheat gluten powder is added to be stirred to form a homogeneous slurry substance, and thus, label glue is obtained. The present invention solves the problems of poor ice water resistant performance, high formol carcinogen content, high consumption of expensive raw materials, high product cost, etc. in the existing label glue.
Description
Technical field
The present invention relates to label glue and preparation method thereof, relate in particular to a kind of high speed water resistant metal label glue and preparation method thereof.
Background technology
High speed water resistant label glue is mainly used on the labeling of industries such as food, medicine, agricultural chemicals.Especially need a large amount of high-quality trade mark adhesives on the bottle of food service industry.Fast development along with China's brewing industry, beer production producer adopts advanced packaging line one after another, the machine speed of many Labelling Machines has been brought up to more than 20,000 bottles/hour, and this just needs, and a large amount of initial bonding strengths are big, curing speed fast, good fluidity, the label glue of excellent performance.At present, the domestic tackiness agent that is used for the quick decals of beer mainly contains polyvinyl alcohol and casein series glue.The defective of polyvinyl alcohol glue maximum is the ability of its anti-frozen water, particularly pastes metal label, cannot satisfy the iced needs of beer; For this produces polyvinyl formal label glue to polyvinyl alcohol after formal is handled, this has improved water resistance to a certain extent, but formaldehyde does not have complete polycondensation in glue, often there is considerable part to exist with unbound state, product between the usage period progressively to around distribute, contaminate environment unfavorablely is applied to food product pack.Casein glue environmental protection, use properties are also excellent especially, and main raw material---the casein food grade proportioning is big in the prescription but commercially available casein glue is general, make cost high, have limited it and have used widely and promote.
Summary of the invention
Technical problem to be solved by this invention is: a kind of overcome above-mentioned deficiency, high speed water resistant metal label glue with low cost and preparation method thereof are provided.
Technical scheme of the present invention is:
A kind of high speed water resistant metal label glue, its main composition and weight percent are: wheat gluten flour 2～10, casein food grade 0～16, polyvinyl alcohol 3～10, W-Gum 2～8, urea 12～20, zinc sulfate 0.4～1.6, yellow soda ash 0.2～0.8, water 50～65; By weight percentage, get polyvinyl alcohol 3～10%, add water 20～40%, insulated and stirred 40min in water-bath more than 95 ℃, cooling, add urea 12～20% and water 25～30%, maintain the temperature at 60～80 ℃, add casein food grade 0～16%, W-Gum 2～8%, zinc sulfate 0.4～1.6% and yellow soda ash 0.2～0.8%, insulated and stirred 120min, after treating that temperature is reduced to below 45 ℃, add wheat gluten flour 2～10% and stir, become the homogeneous soup compound promptly to get label glue.
Also comprise 0.01～1% Sodium Benzoate, 0.02～1% defoamer.
Described defoamer is a propyl carbinol.
Another technical scheme of the present invention is:
A kind of preparation method of high speed water resistant metal label glue, by weight percentage, get polyvinyl alcohol 3～10%, add water 20～40%, insulated and stirred 40min in water-bath more than 95 ℃, cooling, add urea 12～20% and water 25～30%, maintain the temperature at 60～80 ℃, add casein food grade 0～16%, W-Gum 2～8%, zinc sulfate 0.4～1.6% and yellow soda ash 0.2～0.8%, insulated and stirred 120min, treat that temperature is reduced to below 45 ℃ after, add wheat gluten flour 2～10% and stir, become the homogeneous soup compound promptly to get label glue.
The Sodium Benzoate that can also add 0.02～1% defoamer and 0.01～1% after stirring into the homogeneous soup compound again stirs and promptly gets label glue.
Beneficial effect of the present invention is: the one, and this metal label glue does not use formaldehyde, non-stimulated smell, no harmful chemical component, readily biodegradable, compliance with environmental protection requirements; The 2nd, no intermediate product discharging in the whole technological process and cause environmental pollution; The 3rd, this metal label glue adopts wheat gluten flour as raw material, and production cost is cheap relatively; The 4th, this metal label glue initial bonding strength is good, and viscosity is adjustable between 30000～100000mPas; The excellent performance of anti-the frozen water, under the situation of temperature≤4 ℃, the anti-frozen water time was greater than 72 hours; And be easy to the high temperature alkali cleaning, in 75 ℃, 2% sodium hydroxide solution, elution time was less than 80 seconds; Curing speed is fast, and fiber tearing in 30 seconds is applicable to manual and mechanical adhesive paper or tinsel label.This metal label glue overall performance and casein glue are suitable, are a kind of environmentally friendly products.
