Abstract
The invention discloses a pre-coated base film, and belongs to the field of polymer composites. The pre-coated base film is composed of a base material and a hot melt adhesive layer, wherein a polyester film is taken as the base material; the hot melt adhesive layer is composed of the following components in parts by weight: 100 parts of low density polyethylene, 10 to 20 parts of ethylene-vinyl acetate copolymer, 1 to 3 parts of silicon dioxide, 20 to 40 parts of rosin, 2 to 6 parts of polyethylene wax and 0.07 to 0.3 part of antioxidant. The pre-coated base film has a thin and transparent characteristic and is high in barrier property and smooth and bright in surface, so that the glossiness and the fastness of a printed product are improved. The pre-coated base film is rich in stereoscopic impression and has the advantages of water resistance, fouling resistance, abrasion resistance and chemical corrosion resistance. Thus, the pre-coated base film disclosed by the invention can be widely applied to the markets of publication printing products and various packaging products.
Description
?
Technical field
The invention belongs to field of polymer composite material, specifically a kind of precoating basement membrane.
Background technology
Namely solvent-borne type is coated with technology due to used benzene solvent and can forms serious harm to the health of the producer, human consumer, namely be coated with technology by water-based gradually to replace, there is the pollution problem after needing the cleaning of large water gaging and discharge cleaning sullage in the water-soluble technology that is namely coated with, it not still optimal environment-friendly type overlay film solution, meanwhile, it still has certain defect in quality product and production efficiency.
Pre-coating film is pollution-free, the tacky environment-friendly type covering material of one hot melt adhesive or low-temperature resins and film substrate are composited by specific equipment; directly attach to article surface by special equipment for coating film in use, decoration and provide protection are played to article.
Summary of the invention
The object of the invention is to prior art defect, a kind of precoating basement membrane is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of precoating basement membrane, described precoating basement membrane is made up of base material and hot melt adhesive layer, described base material is polyester film, and described hot melt adhesive is made up of the component of following weight part: Low Density Polyethylene 100 parts, ethylene-vinyl acetate copolymer 10-20 part, silica 1-3 parts, rosin 20-40 part, polyethylene wax 2-6 part, oxidation inhibitor 0.07-0.3 part.
In described ethylene-vinyl acetate copolymer, the massfraction of vinyl acetate is 10-15%.
Described oxidation inhibitor is antioxidant 1010.
Beneficial effect of the present invention: precoating basement membrane of the present invention has thin and transparent feature, there is high barrier, surface smoothing light, improve glossiness and the fastness of printed matter, is rich in stereoscopic sensation, there is the advantage of waterproof, antifouling, wear-resisting, resistance to chemical attack, be widely used in publication printed matter market and all kinds of packaged product market.
Embodiment
Embodiment 1
By starting silica 1 part, rosin 25 parts, polyethylene wax 2 parts, the fusing of 0.1 part, oxidation inhibitor, then add Low Density Polyethylene 100 parts, ethylene-vinyl acetate copolymer 11 parts fusing, stir obtained hot melt adhesive.
