Problems solved by technology

[0002] With the improvement of living standards, the use of automobiles is also increasing year by year. The relationship between vehicles and human beings is inseparable. The relationship between vehicle manufacturers and vehicle component manufacturers and drivers is not only the pursuit of the performance and safety of the vehicle itself. As well as the fuel-saving effect, more and more attention is paid to the aesthetics of the inside and outside of the car body and the decorative components inside and outside the car body. For example, in order to make the surface of the existing car decorative panels more beautiful and high-end, multi-layer composites are usually used, but Due to its unreasonable structural arrangement and unreasonable treatment, the existing automobile decorative panels are prone to defects such as cracking and rusting, so it is necessary to improve the existing technology

Embodiment 1

[0019] Such as figure 1 As shown, the structure of the automotive decorative board includes a non-woven fabric layer 1, an aluminum layer 2, a beech wood layer 3, a fiberboard layer 4 and a walnut wood layer 5 from the inside out, and the thickness of the non-woven fabric layer 1 is 0.2 mm. The thickness of aluminum part layer 2 is 0.5mm; The thickness of beech wood layer 3 is 0.3mm; The thickness of fiberboard layer 4 is 0.3mm; Composed of flame retardant formula and waterproof formula, the dry weight ratio of wood fiber, bonding formula, flame retardant formula and waterproof formula is 90:5:4:1, wherein the flame retardant formula includes the following raw materials and weight Specific components: 16 parts of dicyandiamide, 12.0 parts of ammonium dihydrogen phosphate, 5.0 parts of formaldehyde, 10.0 parts of zinc borate, 5.0 parts of ammonia water, 3.0 parts of triethanolamine, 4.0 parts of ethylene propanol, 5 parts of hexamethylenetetramine and 40.0 parts of water, the ...

Embodiment 2

[0021]The difference between the second embodiment and the first embodiment is that the flame retardant formula includes the following raw materials and components by weight: 16.0 parts of dicyandiamide, 24.0 parts of ammonium dihydrogen phosphate, 7.0 parts of formaldehyde, zinc borate 13 parts, 18.0 parts of ammonia water, 3.0 parts of triethanolamine, 4.0 parts of ethylene propanol, 1.0 parts of hexamethylenetetramine and 14 parts of water, spray the mixture of flame retardant formula, adhesive formula and bonding formula after hot grinding After drying, paving, hot pressing, and sanding processes, the fiberboard layer 4 is made on the wood fiber. When the surface of the aluminum layer 2 is electrolytically oxidized first, the wax is removed before the electrolytic oxidation: the aluminum layer 2 Put it into the wax removal solution and treat it for 180 seconds at a temperature of 70°C under the condition of external ultrasonic waves. The concentration of the wax removal sol...

Embodiment 3

[0023] The difference between Example 3 and Example 1 is that the flame retardant formula includes the following raw materials and components by weight: 10.0 parts of dicyandiamide, 10.0 parts of ammonium dihydrogen phosphate, 10 parts of formaldehyde, zinc borate 15 parts, 15 parts of ammonia water, 10 parts of triethanolamine, 10 parts of ethylene propanol, 5 parts of hexamethylenetetramine and 15 parts of water, spray the mixture of flame retardant formula, adhesive formula and bonding formula after hot grinding After drying, paving, hot pressing, and sanding processes, the fiberboard layer 4 is made on the wood fiber. When the surface of the aluminum layer 2 is electrolytically oxidized first, the wax is removed before the electrolytic oxidation: the aluminum layer 2 Put it into the wax removal solution and treat it for 180 seconds at a temperature of 65°C under the condition of external ultrasonic waves. The concentration of the wax removal solution is 150g / l; the wax remo...

Abstract

The invention belongs to the technical field of automobile accessories and provides an automobile decorative sheet layer structure and the layer structure processing technology of the automobile decorative sheet layer. The automobile decorative sheet layer structure structurally comprises a non-woven layer, an aluminum part layer, a beech layer, a fiberboard layer and a walnut layer from inside to outside. The fiberboard layer is formed by wood fibers, a bonding formula, a flame-retarding formula and a waterproof formula. According to the processing technology, firstly, electrolytic oxidation is performed on the surface of the aluminum part layer, wax removing is performed before electrolytic oxidation, and a mixture of the flame-retarding formula, a gluing formula and the bonding formula is sprayed on the wood fibers which undergo hot grinding, and the fiberboard layer is formed through the procedures of drying, paving, hot pressing and sanding. The automobile decorative sheet layer structure and the layer structure processing technology of the automobile decorative sheet layer have the advantages that the technology processing process is green and safe and protects the environment; all the technology procedures are simple, therefore, yield is improved, a qualification rate is improved, production cost is reduced, and maintenance is easy; the layer structure after being processed is reasonable in layout, beautiful in appearance, and good in corrosion resistance, and the defects such as cracking and rusting are overcome; meanwhile, a high-quality film layer is formed on the outer surface of the layer structure, and therefore the corrosion resistance performance is enhanced.
