Description
Technical field
The present invention relates to of preparation method and the application of a kind of vacuum aluminium-plated paper with hard-gloss paint.
Background technology
Vacuum aluminium-plated paper mainly is made up of body paper, aluminium lamination and coating, and its glossiness and smoothness are good, and pliability is good, and the sprayed-on Al layer fastness is high, and environmental protection attractive in appearance has good printing performance and machining property simultaneously.The paper surface strength of aluminizing is high, and the speed of its ability and high-speed press adapts, and also can bear the pulling force that the increment of printing ink stickiness is produced simultaneously, and to enhancing productivity, stable printing quality has good adaptability.The transfer of printing ink when the paper surface tension of aluminizing helps printing, calm, bright and clean, the picture and text complete display of printing prepared Chinese ink film.Therefore can be widely used in the fineness packing of products such as cigarette, wine, bottle subsides, tealeaves, food, cosmetics, daily use chemicals, general merchandise, gift, handicraft.
Because vacuum aluminum-coated surface gloss and smoothness to the body paper of aluminizing that uses had relatively high expectations, and must handle the body paper surface of aluminizing before therefore aluminizing, and promptly is coated with one deck dope on its surface with coating machine, and then aluminizes with vacuum aluminum-coated machine.Glossiness and smoothness that the purpose of coating one deck dope is to solve the uneven problem of paper, improves the surface are convenient to vacuum aluminum-coated.At present, vacuum aluminium-plated paper has solvent-borne type, ethanol-soluble type, an emulsion paint with what hard-gloss paint adopted, wherein contains a large amount of organic solvents in solvent-borne type and the ethanol-soluble type coating, and smell is big, easy environment is polluted.
Chinese patent (CN101250834A) discloses a kind of face-coating paint for processing vacuum-coated aluminum paper; Vacuum aluminium-plated paper through adding preparations such as acrylic resin, acrylate, neutralizer, levelling agent and anti-wear agent has excellent transparency and ABRASION RESISTANCE with painting coating; But need to add anti-wear agent, its storage stability is slightly poor.
Summary of the invention
The purpose of this invention is to provide a kind of vacuum aluminium-plated paper with hard-gloss paint, solving the above-mentioned defective that prior art exists.
Vacuum aluminium-plated paper of the present invention is used hard-gloss paint, and each component and parts by weight are following:
0.5～2.0 part of hydroxyl acrylic resin
2～10 parts of polyvinyl alcohol
5～35 parts of acrylic resins
0.5～15 part of neutralizer
100 parts of acrylates
0.1～1.0 part of antifoaming agent
0.2～0.8 part of levelling agent
500～1000 parts in water
Described hydroxyl acrylic resin is selected from least a in hydroxy-ethyl acrylate, single acrylic acid binaryglycol ester or the hydroxypropyl acrylate;
Described neutralizer is selected from least a in triethylamine, diethylamine, diethanol amine or the triethanolamine;
Described levelling agent is selected from least a in dimethyl silicone polymer, polyester modification organosilicon or the silicone modified polyacrylate;
Described antifoaming agent is selected from least a in tributyl phosphate, dimethicone, phenylacetic acid bay alcohol ester or the benzyl carbinol oleate.
The acid number of described hydroxyl acrylic resin is 5～12mgKOH/g, and hydroxyl value is 40～60mgKOH/g; The acid number of described acrylic resin is 150～400mgKOH/g, and molecular weight is 1000～5000; The vitrification point Tg of described acrylate is-10～30 ℃, and acid number is 0～15mgKOH/g;
Described polyvinyl alcohol is a dispersant, weight average molecular weight 2000～10000, and the mole alcoholysis degree is 50～80%.
Vacuum aluminium-plated paper of the present invention comprises the steps: with the preparation method of hard-gloss paint
(1) water with hydroxyl acrylic resin, dispersant, acrylic resin, neutralizer and gross weight 15～60% mixes, and is warming up to 55～80 ℃;
(2) water with product, acrylate, levelling agent, antifoaming agent and the surplus of step (1) mixes, and obtains the hard-gloss paint that vacuum aluminium-plated paper is handled usefulness, and the weight solid content is 15～40%, and the pH value is 5～8.
Vacuum aluminium-plated paper of the present invention is used hard-gloss paint, can be used as the functional aid of paper making and cloth coating process.
The vacuum aluminium-plated paper of the present invention's preparation is used hard-gloss paint, through the dispersant of adding polyvinyl alcohol as emulsion, and adds hydroxyl acrylic resin, and the glossiness of the coating that makes, ABRASION RESISTANCE and storage stability are greatly improved.The inventor infers that its mechanism possibly be that its hydrophilic hydroxyl can make emulsion particle stably be scattered in the system owing to the dispersant of polyvinyl alcohol as emulsion, has strengthened vacuum aluminium-plated paper and has handled with the stability of coating in storage and use.Hydroxyl acrylic resin can stably be suspended in the alkaline decentralized medium, and can make film-forming resin have resolubilization property because it is rich in hydroxy functional group, prevents that printing coating process film-forming resin from depositing on roller bearing.In addition, hydroxyl acrylic resin can improve the cohesive strength that goes up optical coating, improves the ABRASION RESISTANCE of filming and need not to add anti-wear agent, makes glossiness, ABRASION RESISTANCE and the storage stability of coating all obtain improving largely like this.
The vacuum aluminium-plated paper of the present invention's preparation is handled the hard-gloss paint of usefulness, and the weight solid content is 15～40%, and the pH value is 5～8, can overcome the shortcoming of existing technology effectively, and glossiness, abrasion resistance and the storage stability of coating are all improved largely.
