Embodiment 1

[0024] 1. Use 80-mesh, 100-mesh, and 200-mesh sandpaper to polish the flat steel substrate in order to ensure that the surface of the substrate is flat and free of small particle protrusions. The grinding time is 5 minutes, and then the polished steel substrate is cleaned with acetone ultrasonically After 20 minutes, remove debris particles and oil stains on the surface of the steel substrate, and then perform ultrasonic cleaning with absolute ethanol for 10 minutes. During ultrasonic cleaning, the acetone and ethanol can be immersed in the steel substrate, and then dry at 80°C for 10 minutes to make the polished steel substrate The surface is dry, clean and free of stains;

[0025] 2. On the surface of the steel substrate obtained in step 1), evenly brush a layer of 2 mm thick organic silica gel, and use a brush to repeatedly coat for 2 minutes so that the surface of the steel substrate (micro-sized surface defects such as pits and scratches) is covered with organic silica gel...

[0029] 1. Use 80-mesh, 100-mesh, and 200-mesh sandpaper to polish the flat steel substrate in sequence to ensure that the surface of the substrate is flat and free of small particle protrusions. The grinding time is 10 minutes, and then the polished steel substrate is ultrasonically cleaned with acetone for 10 minutes. , remove debris particles and oil stains on the surface of the steel substrate, and then perform ultrasonic cleaning with absolute ethanol for 15 minutes. During ultrasonic cleaning, acetone and ethanol can be immersed in the steel substrate, and then dry at 80°C for 20 minutes to dry the polished steel substrate surface. Clean and free of stains;

[0030] 2. On the surface of the steel substrate obtained in step 1), evenly brush a layer of 3mm-thick organic silica gel, and apply it repeatedly for 5 minutes with a brush to make the surface of the steel substrate (micro-sized surface defects such as pits and scratches) covered with organic silica gel cover;

Embodiment 3

[0034] 1. Use 80-mesh, 100-mesh and 200-mesh sandpaper in sequence to polish the curved steel substrate with a curvature of 25% to ensure that the surface of the substrate is flat and free of small particle protrusions. The grinding time is 15 minutes, and then the polished curved steel substrate The substrate is ultrasonically cleaned with acetone for 15 minutes to remove debris particles and oil stains on the surface of the steel, and then ultrasonically cleaned with absolute ethanol for 15 minutes. During ultrasonic cleaning, the acetone and ethanol are immersed in the steel substrate, and then dried at 80°C for 30 minutes to make the grinding After the steel surface is dry, clean and free of stains;

[0035] 2. Evenly scrape and coat a layer of epoxy resin glue with a thickness of 1mm on the surface of the steel substrate obtained in step 1), and apply it repeatedly for 4 minutes with a brush to make the surface of the steel substrate (micro-sized surface defects such as pi...

Abstract

The invention relates to a composite metal surface protection layer and a preparation method thereof. The preparation method is characterized by comprising the following steps: 1) polishing to flatten a metal base, performing ultrasonic cleaning for 10-20min by sequentially using acetone and absolute ethyl alcohol, and drying for 10-30min; 2) applying 1-3mm organic adhesive to the base surface; 3) attaching 0.12-0.30mm thick ultra-thin glass to the organic adhesive while rolling; fixing the four sides with clamps, and rolling back and forth for 10-30min; 4) solidifying at 20-100 DEG C for 5min to 24h, removing the clamps, clearing the solidified organic adhesive on the four sides and polishing the edge, to obtain 0.15-0.33mm organic / inorganic composite protection layer. The composite metal surface protection layer and the preparation method thereof provided by the invention have the following advantages: (1) the organic protection layer and the inorganic protection layer supplement each other complementary in performance to realize an excellent protection effect; (2) the technology is simple, and the cost is low; (3) the problems that a metal layer is easy to corrode and wear and hard to clean and tends to conduct electricity in a common environment are solved.

Description

technical field [0001] The invention belongs to the technical field of metal protection, and in particular relates to a metal surface composite protection layer and a preparation method thereof. Background technique [0002] In daily life or industrial use, metal materials often encounter different degrees of corrosion, scratches, and friction. However, in some complex use environments and harsh conditions, the surface of metal materials is required to have high hardness, high chemical stability, and low friction. coefficient and insulation properties. It is difficult for metal materials to have such properties. The best solution to this problem is to prepare a high-performance coating on the surface of metal materials. The coatings on the surface of metal materials are usually organic coatings and inorganic coatings. Organic coatings (such as paints, etc.) have excellent anti-corrosion effects, and their preparation methods (usually spraying or brushing) are simple and sui...
