Problems solved by technology

[0006] During the processing of PVC or PET color film, in order to increase the plasticity and strength of the plastic, plasticizers such as phthalates need to be added, but the color film with plasticizer will produce dioxins when burned and other toxic substances, which affect the environment and the health of personnel; and the glue and primer used in the processing of traditional coated color boards contain volatile solvents, which will emit VOC in actual production, pollute the environment, and do not conform to the trend of environmental protection

preparation example Construction

[0041] 1. Preparation example of hot melt adhesive film: Take 60kg linear low density polyethylene resin, 20kg ethylene-vinyl acetate copolymer, 10kg ethylene-octene copolymer, 3kg poly-α-methylstyrene resin, 5kg polyurethane Ester, 0.5kg8-hydroxyquinoline zinc, 1kg vinyltrimethoxysilane, 2kg gum arabic, 5kg talcum powder, 0.3kg antioxidant 1010 are placed in a high-speed mixer, and mix well to obtain a mixture; then the mixture Placed in a twin-screw extruder, the temperature of each section of the twin-screw extruder is 180°C in the first zone, 180°C in the second zone, 185°C in the third zone, 190°C in the fourth zone, 180°C in the fifth zone, and 180°C in the sixth zone. 1. After extrusion and granulation, hot-melt adhesive particles are obtained; then the hot-melt adhesive particles are placed in a casting machine at 120° C., and a hot-melt adhesive film is obtained through casting processing.

Embodiment 1

[0044] Embodiment 1: a kind of soft feeling coated color board, see figure 1 , its layer structure from bottom to top is: metal substrate 10, chemical treatment layer 20 formed on the surface of metal substrate 10, and hot-melt adhesive fiber textile material layer 30 on the chemical treatment layer 20, wherein the hot-melt adhesive fiber textile material The layer 30 includes a hot melt adhesive layer 31 and a fiber textile material layer 32, and the fiber textile material layer 32 is composed of a fiber fabric layer 321 and a PU film layer 322 bonded and compounded.

[0045] A soft-feeling coating material is produced by the following process:

[0046] S1: Prepare the fiber textile material and preheat it to 100°C for later use; then stick a hot melt adhesive film with a thickness of 40 μm on the heated fiber textile material so that the hot melt adhesive film is in contact with the underlying fiber fabric of the fiber textile material , apply pressure to the hot-melt adhes...

Embodiment 2

[0049] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the preheating temperature of the fiber textile material in S1 is 70°C, the thickness of the hot melt adhesive film is 4 μm, and the pressing pressure of the pressure roller is 4kgf; the metal substrate in S3 The heating temperature was 130° C., and the pressing pressure of the pressure roller was 4 kgf.

Abstract

The invention discloses a soft film-coated color plate and a production process thereof and relates to the technical field of plates for household appliance shells. The key points of the technical scheme are that the soft film coated color plate comprises a metal substrate, a chemical treatment layer formed on a surface of the metal substrate, and a hot melt adhesive fiber textile material layer arranged on the chemical treatment layer, the hot melt adhesive fiber textile material layer is composed of a hot melt adhesive layer and a fiber textile material layer, the fiber textile material layer is composed of a fiber fabric layer and a PU film layer, one side of the hot melt adhesive layer is in contact with the chemical treatment layer, and the other side of the hot melt adhesive layer isin contact with the fiber fabric layer. The hot melt adhesive fiber textile material is attached to the metal substrate to form the film-coated color plate, glue and paint are not used, VOC emissionin the production environment can be reduced, and therefore the soft film-coated color plate with the appearance having soft high-grade texture, colorful color changes, rich functionality and excellent durability is obtained.

Description

technical field [0001] The invention relates to the technical field of boards for home appliance casings, more specifically, it relates to a soft-feeling film-coated color board and a production process thereof. Background technique [0002] The traditional film-coated color plate is made of stainless steel, hot-dip galvanized steel plate, electro-galvanized steel plate, cold-rolled steel plate, galvanized aluminum plate and other materials, and the surface is coated with color film. It is mainly used in refrigerators, washing machines, Shells of home appliances such as air conditioners. [0003] The traditional VCM steel plate is chemically treated on the surface of the metal substrate, glue is coated on the obtained chemically treated layer, and then the steel plate coated with glue is heated, and then PET / PVC composite film is laminated on the steel plate to obtain the VCM steel plate ; Sometimes, in order to ensure the smoothness of the surface and increase the brightne...
