Problems solved by technology

[0006] However, the characteristics of high surface energy and large specific surface area of ​​nanoparticles make it easy to agglomerate between particles; in addition, the compatibility between inorganic nanoparticles and matrix resin is poor, and phase separation is prone to occur during the mixing process
The agglomeration of nanoparticles in the matrix resin not only affects the appearance of the product, but also causes defects in the microstructure of the product, resulting in a decrease in the mechanical properties of the composite material and failing to achieve the purpose of modifying the properties of the resin.
In order to make the nanoparticles have a good dispersion effect in the matrix resin and achieve the purpose of modification, the surface of the nanoparticles is usually modified, and the nanomaterials can also change the problem of single functionality of the aluminum veneer

Embodiment Construction

[0031] A method for manufacturing an environment-friendly aluminum veneer, comprising the following steps:

[0032] A. Sheet metal preparation; choose 2-4mm thick aluminum veneer for sheet metal processing, the processing steps include cutting board blanking, scribing and opening corners, punching corner code holes, bending forming, welding and splicing, and adding reinforcement , laser drilling, grinding and polishing;

[0033] B. Surface pretreatment: Use an air mill to grind the sprayed surface to remove scale, use a degreasing agent to perform oil removal treatment, and use tap water to rinse the surface of the aluminum veneer until no water drops hang, which is considered to be completely clean after degreasing;

[0034] C. Primer layer treatment: Spray the sheet metal with fluorocarbon series water-based paint. After spraying, preheat at 60-80°C for 15 minutes;

[0035] D. Topcoat layer treatment: spray nano-modified light-cured coating on the surface of the primer laye...

Abstract

The invention discloses an environment-friendly aluminum veneer manufacturing method. The environment-friendly aluminum veneer manufacturing method comprises the steps of metal plate preparation, primer layer treatment, finishing coat layer treatment and varnish layer treatment, and the finishing coat uses a nano-ATO modified photocurable coating. The aluminum veneer manufacturing method skillfully utilizes nano materials in the coating to achieve the environment-friendly coating concept, and imparts the heat insulation effect on the aluminum veneer at the same time.

Description

technical field [0001] The invention relates to a processing method of an aluminum veneer, in particular to an environment-friendly manufacturing method of an aluminum veneer. Background technique [0002] Green and environmentally friendly coatings are called "environmentally friendly coatings", and water-based ultraviolet curing coatings (UVCC) have become one of the main development directions of "environmentally friendly coatings". The principle of photocurable coatings is to stimulate the photoinitiator with ultraviolet light to initiate the polymerization reaction of the photocurable resin, thereby curing and forming. The main components of photocurable resins are: oligomers, reactive diluents, photoinitiators and additives. [0003] The research on photocurable resins in China started in the early 1970s. Due to technical reasons, there were defects in the stability, color and photosensitivity of the initial resins, and the research and application of photocurable res...
