Abstract
A disclosed coating for aluminium plated paper is characterized by comprising the following compositions in parts by weight: 15-25 parts of an acrylate, 20-40 parts of nitro cellulose, 15-25 parts of polyurethane, 5-10 parts of acrylic acid, 20-30 parts of an acrylate emulsion, and 90-110 parts of an alcohol solution. According to the technology, alcohol is employed as a solution and can be completely reacted with the acrylate, no toxic solvent is generated and environment is not polluted. The acrylate emulsion and the acrylate are employed at the same time as glue materials, are further reacted with the solution while the binding purpose is reached, and no toxic solution is left in the binder.
Description
Technical field
The present invention relates to a kind of packaging material field, especially a kind of aluminium paper Material Field of airless spraying.
Background technology
Vacuum aluminium paper, or claim aluminium paper, aluminized paper, evaporation paper, be play the novel green packaging material being applied in packaging industry in the world more and more widely the eighties in 20th century.Due to its metal-like, reliable and stable printing performance and degradable noble attractive in appearance, callable beneficial environmental properties, be subject to liking of people more and more.Aluminium paper aluminum amount is few, degradability good, can save production cost, and can not cause environmental pollution, belonging to environment-friendly packaging material, is the alternative AKU package material of aluminum foil composite paper plate simultaneously.Aluminium paper because of glossiness and smoothness good, pliability is good, and sprayed-on Al layer fastness is high, has good printing performance and machining property simultaneously, therefore can be widely used in the fineness packaging of the products such as cigarette, wine, bottle sticker, tealeaves, food, cosmetics, handicraft, also can be used for Building Decoration Material.Because the production technology of aluminium-plated transfer method is comparatively complicated, high in technological content, equipment investment is large, production cost is very high, existing spraying method requires higher to adhesive simultaneously, in the solution of adhesive, remaining a small amount of organic solvent, easily causes environmental pollution, can not reach the requirement of environmental protection.
Summary of the invention
Goal of the invention: the object of the invention is for the deficiencies in the prior art, provides one to reduce costs, simultaneously the coating of the aluminium paper of green non-pollution;
Another object of the present invention is to provide a kind of technique using described coating to carry out aluminium paper spraying.
Technical scheme: the coating of aluminium paper of the present invention, comprises following component:
Acrylate 15 ~ 25 parts;
NC Nitroncellulose 20 ~ 40 parts;
Polyurethane 15 ~ 25 parts;
5 ~ 10 parts, acrylic acid;
Acrylate emulsion 20 ~ 30 parts;
Alcoholic solution 90 ~ 110 parts
With parts by weight.
As preferably, the coating of described aluminium paper, comprises following component:
Acrylate 20 parts;
NC Nitroncellulose 30 parts;
Polyurethane 20 parts;
8 parts, acrylic acid;
Acrylate emulsion 25 parts;
Alcoholic solution 100 parts
With parts by weight.
The technique of aluminium paper spraying of the present invention, comprises the following steps:
(1) coating preparation: acrylate, NC Nitroncellulose, polyurethane, acrylic acid are prepared to join in alcoholic solution by weight and stirs, then sizing material acrylate emulsion is joined in alcoholic solution, continue to stir;
(2) be coated with: by coating machine by coatings on film, dry-coated amount during coating is 1.6 ~ 2.0g/ ㎡, and surface corona value is 50 ~ 60;
(3) aluminize: the laggard row of film pressing mold be coated with is aluminized;
(4) face is coated with: film is put into coating machine, is coated with on body paper, the painting amount of coating machine is 210 ~ 230g/ ㎡.
Preferably, described film is PET film.
Preferably, the TG point of described sizing material acrylate emulsion is 40 ~ 50 DEG C.
Beneficial effect: (1) the present invention uses alcohol as solution, fully can react, do not produce toxic solvent with acrylate, free from environmental pollution; (2) sizing material of the present invention adopts acrylate emulsion and acrylate to use simultaneously, while reaching and bonding object, further with solution reaction, can not in adhesive remaining toxic solution.
