Abstract
The present invention provides preparation and application of polyester vacuum aluminium plating film (VMPET) baking varnish with high performance and quick drying. The baking varnish is formed by preparing amino resin, varnish material resin (film forming resin), auxiliary resin, dye, solvent and assistant, and the baking varnish is coated on a PET vacuum aluminium plating film under the temperature condition of 180 to 250 DEG by 30 to 80 m/min of production line speed in a roller way to form a solidity varnish film after rapidly solidified and dried. The fixed contents of the manufactured amino baking varnish are 15 to 30%, the fineness is 15 to 25 um, the thickness of the manufactured varnish film is 10 to 25 micrometres, and the varnish film is full and smooth and can not fade by boiling for 20 to 30 minutes in alkaline water solution. The present invention can be used as adornments to be widely used for fabric or garments because of excellent decoration performance and materialized performance of the polyester vacuum aluminium plating film (VMPET) baking varnish.
Description
Technical field
The present invention relates to chemical field, is a kind of high-performance quick-drying PET Al metallizing Fool (VMPET) baking finish and preparation method thereof.
Background technology
The polyester vacuum aluminized film is given the colouring baking finish with metalluster, but because aluminium coated under the high-temperature alkaline condition, in the high temperature soda boiling dyeing and steam fixation technology as fabric, easily oxidizedly causes the paint film toning; In addition, paint film inadequately densification also cause the colored paint loss of gloss to fade.With PET gold and silver aluminium plating film is example, and high-grade fabric is as silk, when the metallized thread after cutting with PET gold and silver aluminium plating film interweaves, must use not oxidized metallized thread, mainly be because the aluminium coated of fabric alkaline condition meeting oxidation metallized thread when dyeing makes the metallized thread delustring fade.The not oxidized PET gold and silver Al metallizing Fool of development generally has two kinds of methods at present: a kind of method is a physical method, promptly is easy oxidation PET aluminium plating film colored paint, two-layer up and down sticking and form for transparent dacron membrane, the aluminium plating film that makes colouring is because of ingress of air is not oxidized; Another kind method cost is lower, promptly develops high temperature resistant painted colored paint, and last colored paint is by directly solidifying to form the Baking Paint protective layer of alkaline-resisting oxidation after toasting.By the second method design, owing to there is not special-purpose Baking Paint, the preparation of domestic non-oxidizing PET aluminium plating film colored paint is dependence on import to a great extent mostly for the production technique of the enterprise of domestic production PET gold and silver Al metallizing Fool at present; Or use homemade surface decoration with baking finish and coiled material baking finish, and making behind the interpolation auxiliary addition agent, products obtained therefrom because alkali resistance is not enough or density is not enough, causes aluminium lamination to come off in dyeing and fixation process easily, and colored paint fades; Still there are a certain distance in quality and imported product.Domestic patent or the bibliographical information that the special-purpose baking finish of polyester vacuum aluminized film is not arranged so far.
