Problems solved by technology

For example, ABS materials have no metal effect, metal materials cannot be folded and are not resistant to corrosion, PET and PP composite materials have no three-dimensional metal effect
Therefore, there is a lack of a composite material with metallic luster, foldability, corrosion resistance, strong three-dimensional effect, and good simulation effect on the market.

Embodiment Construction

[0018] see figure 1 , The composite film of the present invention is base film 5, anodized aluminum foil (metal layer) 4, polyvinyl chloride transparent semi-rigid sheet 3, ink layer 2, surface film 1 respectively from bottom to top. The ink layer 2 semi-rigid sheet 3 is printed to form a color pattern. Base film 5, anodized aluminum foil (metal layer) 4, polyvinyl chloride transparent semi-rigid sheet 3, surface film 1 is bonded by cold pressing of vinyl acetate resin 6, the gluing temperature is 20 ℃ ~ 40 ℃, and the cold pressing is bonded for 24 hours The post-peel strength is 10N-25N per square centimeter. The thickness h of the composite film is generally 0.3-1 mm.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) In the production process of the base film, the polyvinyl chloride resin is added with nitrile, DOA cold-resistant agent, flame retardant, antistatic agent and other additives according to a reasonable rati...

Abstract

The invention provides a new composite material having strong metallic effect, good flexibility, and folding, oxidizing, cold, acid, alkaline, rust and fire resistances. A metal layer is adhered to polrvinyl chloride soft membrane that is used as a basal membrane; a transparent polrvinyl chloride semi-hard sheet is bonded to the metal layer; colorful patterns are printed on the transparent polrvinyl chloride semi-hard sheet; transparent polrvinyl chloride soft membrane is then bonded to the colorful patterns as a surface membrane; and the binding agent is vinyl chloride / vinyl acetate resin.

Description

technical field [0001] The invention relates to a composite material with metallic luster and three-dimensional effect, which is used in industries such as packaging, clothing, and signs to make ornaments, signs, and the like. Background technique [0002] At present, the raw materials used in packaging, clothing and signs (such as colored food packaging bags, uniform clothing, trademark signs, etc.) include PET composite materials, PP composite materials, OPP paper composite materials, metal materials, ABS materials and so on. These materials only have their own characteristics. For example, ABS materials have no metal effect, metal materials cannot be folded and are not resistant to corrosion, and PET and PP composite materials have no three-dimensional metal effect. Therefore, there is a lack of a composite material with metallic luster, foldability, corrosion resistance, strong three-dimensional effect, and good simulation effect on the market.
