Embodiment 1

[0032] This embodiment is a water-based organic porcelain sprayed aluminum veneer and its manufacturing process, combined with figure 1 and image 3, choose 3.0mm thickness of 3003H24 grade aluminum veneer as the aluminum substrate 1, after pickling, water washing, pre-treatment respectively on the bottom surface and surface of the aluminum substrate 1 to form a passivation layer 2 and a passivation layer 2 3, in the passivation layer The viscosity of the spraying on the first 2 is set at 20-40 seconds according to the characteristics of the water-based paint, and the polyester back paint with a film thickness of 6-10 μm is used as the anti-rust layer. At the same time, the viscosity of the spraying on the passivation layer 23 is set at 10-30 Seconds, water-based pure white paint with a film thickness of 10-20 μm, the spraying line speed is set at 1.5-2m / min, the back paint layer 7 and the primer layer 4 are formed by 60°C preheating section for 10 minutes, and the volatile wa...

Embodiment 2

[0037] In this embodiment, a water-based organic porcelain sprayed aluminum veneer and its manufacturing process are combined figure 2 and image 3 , select 2.0mm thick aluminum veneer of 3003H24 grade as the aluminum substrate 1, after pickling, water washing, and pretreatment, passivation layer 1 and passivation layer 2 and 3 are formed on the bottom and surface of the aluminum substrate 1 respectively, and the passivation layer 2.3 The spraying construction viscosity is set to 10~30s according to the characteristics of the water-based paint, and the thickness of the water-based pure white paint is 10-20μm. The spraying line speed is set to 1.5-2m / min, and it is leveled and volatilized after 10 minutes of pre-heating at 60°C. Moisture forms primer layer 4; select silver water-based organic porcelain topcoat, and spray 20~30μm in the surface spray booth (the construction viscosity is set to 10~30s according to the characteristics of the water-based paint, and the line speed ...

Embodiment 3

[0042] In this embodiment, a water-based organic porcelain sprayed aluminum veneer and its manufacturing process are combined figure 2 and image 3 , select an aluminum veneer with a thickness of 3.0 mm and a grade of 3004H24 as the aluminum substrate 1, and form a passivation layer 1 and a passivation layer 2 on the bottom and surface of the aluminum substrate 1 after pickling, water washing, and pretreatment; The spraying construction on layer 2 and 3 is a water-based pure white background paint whose viscosity is set to 15-30s according to the characteristics of the water-based paint, and the thickness is 10-15μm. Leveling and volatile water form the primer layer 4; select high-gloss yellow water-based organic porcelain topcoat, and complete the 20~30μm topcoat spraying in the surface spray booth. (In order to make the paint surface uniform and the water solvent to be fully pre-volatilized, the topcoat is sprayed twice, and the first thinner topcoat is evenly sprayed (pri...

Abstract

The invention relates to a water-based organic ceramic sprayed aluminum veneer and a manufacturing method thereof, and belongs to the technical field of curtain wall decorative boards. The water-based organic ceramic sprayed aluminum veneer comprises a passivation layer I, an aluminum baseplate, a passivation layer II, a bottom paint layer and a surface paint layer in sequence from top to bottom, wherein the bottom surface and the surface of the aluminum baseplate are conducted by passivation processing to obtain the passivation layer I and the passivation layer II respectively; the bottom paint layer is formed by spraying a water-based organic ceramic material for 15-20 <Mu>m on the passivation layer II; the surface paint layer is formed by spraying the water-based organic ceramic material for 20-30 Mum on the bottom paint layer. The sprayed aluminum veneer has the advantages that the aluminum veneer is controllable in range of glossiness, high in intensity and hardness, scratch resistant, acidproof, highly flame-retardant, and aging-resistant, provided with self-cleaning performance, and large in color choosing space.

Description

technical field [0001] The invention relates to a water-based organic porcelain spray-coated aluminum veneer and a manufacturing process thereof, belonging to the technical field of curtain wall decorative plates. Background technique [0002] With the development of the coatings industry, there are more and more colors, varieties and functions of coatings, and the division of labor is becoming more and more detailed. However, traditional solvent-based coatings mostly use organic solvents such as toluene, xylene, and butyl acetate as diluents, and their manufacturing and construction processes cause huge pollution to the environment due to the large amount of organic solvents discharged. In order to limit the emission of organic solvents, high solidification, solvent-free, and water-based coatings have become increasingly strong, which is what the industry calls "4E" coatings (Economy, Efficiency, Ecology, Energy). Among them, the water-based coating is a field that has dev...
