preparation example Construction

[0033] The present invention provides a method for preparing a fiber decorative film described in the above technical solution, comprising the following steps:

[0034] The substrate layer and the compatible layer are made into the bearing layer, and the transparent thermoplastic layer and the functional layer are made into the surface layer, which are stacked in sequence according to the order of the bearing layer, fiber layer and surface layer, and are carried out in a roll-to-roll continuous compounding manner Laminated to obtain a fiber decorative film.

[0035]In the present invention, the substrate layer and the compatibilizing layer are made into a bearing layer. In the present invention, the compatibility layer is preferably spread on the surface of the substrate layer by methods such as coating, bonding, spraying, etc., and dried to obtain a bearing layer; the drying temperature is preferably 60-150°C.

[0036] The present invention will preferably include but not li...

Embodiment 1

[0045] Spray a silicone coating solution compatibilizer (thickness 50 μm) on the surface of ABS film (thickness 200 μm), and after drying at 90 ° C, a bearing layer is obtained; coat a wear-resistant coating (thickness 25 μm) on the surface of PMMA (thickness 50 μm) to obtain a layer; carbon fiber and aramid fiber are laid and woven to obtain a carbon fiber and aramid twill mixed fiber layer (thickness 220 μm);

[0046] From bottom to top, roll-to-roll continuous lamination is carried out in the order of bearing layer, fiber layer, and surface layer under heating and pressure conditions. After winding, the fiber decorative film is obtained;

[0047] Open the lower cavity of the vacuum blister forming machine, put in the injection molded parts and the fiber decorative film, preheat the fiber decorative film (preheating temperature 120°C), when the fiber decorative film reaches the preheating temperature , close the lower chamber of the molding machine, open the valve of the va...

Embodiment 2

[0049] Spray silicone coating liquid compatibilizer (thickness 75μm) on the surface of PP film (thickness 300μm), dry at 110°C to get bearing layer; coat UV resin (thickness 25μm) on PC surface (thickness 350μm), emboss with pattern roller Finally, the surface layer is obtained by 365nm UV light curing; the carbon fiber is woven according to the 3K twill weave, and the 3K twill carbon fiber layer is obtained;

[0050] From bottom to top, roll-to-roll continuous lamination is performed under heat and pressure in the order of bearing layer, carbon fiber layer, and surface layer. After pressing and rolling, a carbon fiber decorative film is obtained;

[0051] Open the upper and lower chambers of the thermocompression molding machine with the desired shape and preheat to 200°C, put in the carbon fiber decorative film, pressurize and close the upper and lower chambers at a pressure of 16 MPa, hold the pressure for 3 minutes, take it out, and trim the edges to obtain A carbon fiber...

Abstract

The invention belongs to the technical field of decorative materials, and particularly relates to a fiber decorative film and a preparation method and product thereof. The fiber decorative film is free of VOC, excellent in mechanical property, high in specific strength and specific rigidity, low in weight and good in surface quality; the fiber decorative film has good thermoplasticity, the productwith the complex geometrical shape can be prepared, no new mold needs to be developed, forming is easy and convenient, the speed is high, and the high yield and the short processing period can be achieved; the product prepared from the fiber decorative film is diversified in texture, has design flexibility and customization, has a beautiful appearance effect and is a feast for the eyes; and the product prepared from the fiber decorative film can be recycled, and thus waste and environment pollution are reduced to the utmost extent.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a fiber decorative film, a preparation method and a product thereof. Background technique [0002] With the development of science and technology, people increasingly need lighter and thinner products. Since carbon fiber can be combined with other materials to obtain materials that are as strong as metal, have high specific stiffness, specific strength and light weight, they are widely used in various industries. favored by the industry. In addition, carbon fiber can produce a unique dynamic three-dimensional texture after weaving. This dynamic three-dimensional effect can make the product have a strong texture, so it is widely used in the interior and exterior of automobiles, home appliances, electronic products, bags and other shells or decorative materials. prospect. [0003] At present, the decoration of carbon fiber is mainly to lay carbon fiber in a mold with...
