Embodiment 1

[0018] Follow the steps below to upholster a car seat:

[0019] a. Use a hot-melt spray gun to spray hot-melt glue on the surface of the seat polyurethane foam pad. The glue spray gun includes a glue spray motor, a glue machine cylinder, a rubber hose, and a glue gun. Put the glue into the glue machine cylinder, seal the cylinder head, flush into nitrogen protection, and set the heating temperature. The heating temperature parameters are set as follows: cylinder body temperature 130-150°C, rubber hose temperature 140-160°C, glue gun temperature: 160-170°C. After the glue is completely melted, the glue spraying motor starts automatically to start the glue spraying operation. In actual operation, the flow of glue can be controlled by adjusting the working current of the glue spraying motor. The amount of glue sprayed is subject to the guarantee of bond strength. Among them, 30-50g / m 2 preferred. The way of glue spraying can be filament, spiral, point, (helical is preferred)...

Embodiment 2

[0025] Follow the steps below to upholster a car seat.

[0026] a. Spray the hot melt adhesive on the surface of the seat polyurethane foam pad with a glue gun, and cure it at room temperature for 30-60 seconds to form a cured adhesive layer;

[0027] b. Wrap the cover on the polyurethane foam pad with a cured adhesive layer, shape it, and position the seat on the relevant frame at the same time;

[0028] c. Use a steam electric iron to iron the glue spraying part, and heat the cured glue layer to melt again through steam heating, so that the glue layer is adsorbed on the surface of the face cover and the polyurethane foam pad;

[0029] d. Cool and shape in natural circulation air, so that the face cover and the polyurethane foam pad are bonded together.

[0030] The method of this embodiment can adopt simple equipment, which is suitable for the production of few varieties and small batches.

Abstract

The invention provides a method for coating a surface cover of an automobile seat, which comprises the steps of: spraying a hot melt adhesive by a spraying gun on the surface of polyurethane foam pad of the seat, and curing for 30-60s at normal temperature; coating the surface cover on the polyurethane foam pad with a cured adhesive layer and reshaping; melting the cured adhesive layer again by high temperature steam; and cooling and forming. The method provided by the invention is simple to operate, and saves the man hour. The surface cover is stiff and smooth in shape and full without drapes and is more suitable for production of seat which has complicated appearance, thereby greatly enhancing the decorative effect of the seat.

Description

[0001] Field: [0002] The invention relates to an installation method of an automobile interior decoration, in particular to a covering method of an automobile seat cover. Background technique [0003] Seats in automobiles are usually covered with upholstery. The covering process of the traditional car seat cover is to use suspenders, steel wires, C-shaped rings or Velcro belts, and special plastic buckles to connect the cover with the polyurethane foam cushion. This method takes a long time to operate, consumes a lot of auxiliary materials, the cover and the seat are not suitable, and the shape is not full. Especially for seats with complex shapes, the covering effect is even worse. Contents of the invention [0004] The purpose of the present invention is to provide a new coating method for automobile seat cover, which has high production efficiency and good coating effect. [0005] The purpose of the present invention is achieved through the following technical soluti...
