Abstract
The present invention provides a waterproof and environmental protection label glue and a manufacturing method thereof. The waterproof and environmental protective label glue is mainly composed of the following ingredients, such as water, polyvinyl alcohol, acrylic acid, butyl acrylate, acrylamide, styrene, ammonium persulfate and sodium bicarbonate. The manufacturing method is formed by that the ingredients go through polymerization in a polyvinyl alcohol aqueous solution via an initiator. The waterproof and environmental protective label glue has the advantages of simple manufacturing process, low cost, good water resistance and no harmful substance discharge, belongs to an environmental protection product and meets the requirements of the high-speed production line of bottled products at present.
Description
Technical field
The present invention relates to adhesive area, is the water-fast environmental protection label glue that a kind of bottled product is used specifically.
Background technology
Adhesive for trade mark is the important step of image appearance in the packing of product always, be widely used in industries such as beer, liquor, tinned food, medicine, agricultural chemicals, chemical reagent, different wrapping material, different conditions such as production rate, tackiness agent there is different requirements, especially in the beer production industry, at first it wants that viscosity is big, good fluidity, tack are strong, it is short to solidify time of drying; Secondly it will have certain mildew-resistant sex change and water tolerance, and is not mouldy in a humid environment, is placed on not fall mark in frozen water or the refrigerator; Returnable bottle also should be easy to clean under certain conditions simultaneously.
The trade mark adhesive of the packaging industry of China application at present has starch based, polyvinyl formal class, casein glue class etc.But the starch based tack is poor, set time slowly, easily go mouldy; The polyvinyl formal class can discharge the deleterious formaldehyde to the mankind, influences people's health; Advantages such as although casein glue has water-tolerant, tack is strong, set time is fast, good fluidity.But now the market value of casein food grade per ton up to 4.5 ten thousand yuan about, cause that the cost of casein glue is per ton to reach more than 10,000 yuan, the increase of product cost directly influences the economic benefit of producer, causes applying of this product to be under some influence.
Summary of the invention
At the problems referred to above, purpose of the present invention is developed a kind of excellent property exactly, a kind of water-fast environmental protection label glue with low cost.
Each composition of a kind of water-fast environmental protection label glue that the present invention realized is by weight:
1000 parts of acrylamide 1-30 of water part
Polyvinyl alcohol 100-250 part vinylbenzene 8-25 part
Vinylformic acid 20-70 part ammonium persulphate 1-3 part
Butyl acrylate 5-20 part sodium bicarbonate 10-35 part.
The preparation method of a kind of water-fast environmental protection label glue that the present invention realized is as follows:
(1) 100-250 part polyvinyl alcohol is added in 1000 parts of water, stirring heating makes the polyvinyl alcohol dissolving, makes polyvinyl alcohol water solution;
(2) 1-3 part ammonium persulphate is added in the polyvinyl alcohol water solution, stir 5min, slowly add vinylformic acid 20-70 part, butyl acrylate 5-20 part, acrylamide 1-30 part, vinylbenzene 8-25 part down at 70 ℃, slowly be warming up to 80-90 ℃, then insulation reaction 1-2h;
(3) add sodium bicarbonate 10-35 part in above-mentioned reactant, stir 15min, make PH=7-8, cooling gets final product.
A kind of water-fast environmental protection label glue that the present invention realized satisfies the requirement of high-speed production lines through overtesting, and aluminium foil is had good stickup, and water tolerance is superior, and is easy to clean in the wash bottle process, does not have the release of objectionable impurities, belongs to environmentfriendly products.
Specific implementation method:
Embodiment 1
A kind of water-fast environmental protection label glue, its each component is by weight ratio: polyvinyl alcohol: 150kg, vinylformic acid: 35kg, butyl acrylate: 5kg, vinylbenzene: 10kg, acrylamide: 12kg, ammonium persulphate: 1kg, sodium bicarbonate: 18kg, water: 1000kg.Its production method stirs in the entry and slowly heating for polyvinyl alcohol is added, and makes the polyvinyl alcohol dissolving be cooled to 70 ℃ of mixtures that add ammonium persulphate and vinylformic acid, butyl acrylate, vinylbenzene and acrylamide then; Slowly be warmed up to 80-90 ℃ again, insulation reaction 1-2h adds sodium bicarbonate again and stirs 15min, transfers PH=7-8, last cooling discharge.
Embodiment 2
A kind of water-fast environmental protection label glue is by weight ratio: polyvinyl alcohol: 180kg, vinylformic acid: 40kg, butyl acrylate: 6kg, vinylbenzene: 12kg, acrylamide: 5kg, ammonium persulphate: 1.2kg, sodium bicarbonate: 19kg, water: 1000kg.Production method stirs in the entry and slowly heating for polyvinyl alcohol is added, make the polyvinyl alcohol dissolving, be cooled to the mixture of 70 ℃ of adding ammonium persulphates and vinylformic acid, butyl acrylate, vinylbenzene, acrylamide then, slowly be warmed up to 80-90 ℃ again, insulation reaction 1-2h, add sodium bicarbonate and stir 15min, transfer PH=7-8, last cooling discharge.
Claims (1)
1, a kind of water-fast environmental protection label glue is characterized in that each composition is by weight: 1000 parts in water, polyvinyl alcohol 100-250 part, vinylformic acid 20-70 part, butyl acrylate 5-20 part, acrylamide 1-30 part, vinylbenzene 8-25 part, ammonium persulphate 1-3 part, sodium bicarbonate 10-35 part;
The preparation method of this is water-fast environmental protection label glue was divided into for three steps:
(1) 100-250 part polyvinyl alcohol is added in 1000 parts of water, stirring heating makes the polyvinyl alcohol dissolving, makes polyvinyl alcohol water solution;
(2) 1-3 part ammonium persulphate is added in the polyvinyl alcohol water solution, stir 5min, slowly add vinylformic acid 20-70 part, butyl acrylate 5-20 part, acrylamide 1-30 part, vinylbenzene 8-25 part down at 70 ℃, slowly be warming up to 80-90 ℃, then insulation reaction 1-2h;
(3) add sodium bicarbonate 10-35 part in above-mentioned reactant, stir 15min, make PH=7-8, cooling discharge gets final product.
