Embodiment 1

[0034] The film base layer is made of 0.3mm thick polyvinyl chloride (PVC) material, the fluff is made of 3D (0.8mm) polyester material, and the flocking glue is made of two-component oily polyurethane flocking glue. The upper surface of the film base layer is cleaned and rolled. The winding is smooth, and the electrostatic flocking machine produced by Shandong Xinfeng Flocking Equipment Co., Ltd. is used for electrostatic flocking.

[0035] Put the film to be flocked on the input roller of the electrostatic flocking machine, connect it with the traction film, pass through the drying tunnel, and fix it around the temporary paper tube; adjust the position of the scraper so that it is 0.25-0.3 away from the upper surface of the base film mm, mix the two-component oily polyurethane flocking glue evenly and pour it into the glue tank in front of the scraper, turn on the motor of the electrostatic flocking machine, turn on the temperature of the drying tunnel, and the film base begi...

Embodiment 2

[0038] The base layer of the film is made of 0.1mm thick thermoplastic elastomer (TPE), the fluff is made of 1.5D (0.5mm) acrylic fiber, the flocking glue is two-component water-based polyurethane flocking glue, and the electrostatic flocking equipment is the same as in Example 1.

[0039] Clean the surface of the film and wind it evenly. Put the film base layer to be flocked on the input stick of the electrostatic flocking machine, connect it with the traction film, pass through the drying tunnel, and fix it on the temporary paper tube; adjust the position of the scraper, Make it 0.22-0.28mm away from the upper surface of the base film, mix the two-component oily polyurethane flocking glue evenly and pour it into the glue tank in front of the scraper, turn on the motor of the electrostatic flocking machine, turn on the temperature of the drying tunnel, and the film base begins to slowly Go forward and confirm that the base layer of the film is flat and wrinkle-free; apply glue...

Embodiment 3

[0042]The difference between this embodiment and Embodiment 1 is that the film base is made of 0.2mm thick thermoplastic vulcanizate (TPV) material, the fluff is made of 3D (0.5mm) acrylic fiber material, and the flocking glue is two-component water-based polyurethane flocking glue. The distance between the scraper and the upper surface of the base layer film is 0.25-0.30mm, the speed of fluffing is 100g / min, the flocking voltage of the electrostatic flocking machine is 48KV-62KV, and the temperature of the drying tunnel is 110°C-120°C.

Abstract

The invention discloses a hot laminating flocking film used for being pasted on the surface of decorations, which comprises a base film, the upper surface of the base film is fixed with a villosity layer and the lower surface thereof is provided with a laminating layer for laminating with the surface of decorations, the villosity in the villosity layer is polyester fiber and / or polyamid fiber with fibre number of 1.5D or 3-4D, the base film is a PVC, a PP, a hot melt adhesive film or a multilayer complex film with thickness of 0.05-0.5mm, the invention also provides a manufacturing method of the hot laminating flocking film, in the method, the back surface of the base film after flocking is upward and subjected to corona treatment or glue spreading treatment, the hot laminating flocking film prepared by the method can carry out hot lamination with the decoration body between 140 DEG C and 220 DEG C, and has the advantages of simple technology, short process period, low scrappage, firmpasting, without viscosity at normal temperature, no flange forming or falling off.

Description

technical field [0001] The invention relates to a flocking film on the surface of an ornament and a manufacturing method thereof, in particular to a thermal lamination flocking film and a manufacturing method thereof. Background technique [0002] At present, flocking technology is widely used in the surface decoration of automotive interior parts to achieve the purpose of beauty, shock absorption and noise prevention. Such as flocking on the inner wall of the glove box or the glove box, it can greatly reduce the rattling sound when the objects in the box collide with the box body, play the role of shock absorption and noise prevention, and keep the car quiet. The inner and outer water cuts are implanted to have the functions of sound insulation, dustproof, water seepage prevention and shock absorption. There are mainly two ways to fix the fluff on the interior parts: online flocking and pasting. [0003] The main process of online flocking is as follows: figure 2 As show...
