A kind of nano water-based paint with waterproof, anti-scratch and anti-fingerprint properties and its preparation method and application

Abstract

The invention discloses a nano water-borne coating with water water-proof, scratch-resistant and anti-fingerprint characteristics. The nano water-borne coating consists of the following raw materials by mass: 6-12 percent of silicon dioxide, 1-7 percent of silicon carbide, 1-5 percent of calcium fluoride, 0.125-0.5 percent of a complexing agent, and 75-95 percent of a solvent. The invention further discloses a preparation method of the nano water-borne coating, as well as application of the nano water-borne coating to electronic products, spectacle lenses and automobile glass. When being applied to the electronic products, the spectacle lenses and the automobile glass, the nano water-borne coating has the following advantages: (1) a comprehensive waterproof effect on circuit boards, screens and housings is achieved; (2) contact points are not isolated; (3) the preparation method is extremely simple and only requires direct application; (4) scratches are prevented; (5) fingerprint resistance is realized; (6) moisture and fog protection is achieved; (7) an oleophobic effect is performed; (8) sweat stain resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of inorganic nano surface coating coatings, in particular to a nano water-based coating with waterproof, anti-scratch and anti-fingerprint properties, a preparation method and an application thereof. Background technique [0002] Electronic products have become an indispensable necessity in people's daily life, and even play a corresponding role. People's clothing, food, housing, transportation, education, and entertainment are all closely related and inseparable. The convenience of life has a considerable credit.

Problems solved by technology

[0003] As for electronic products and equipment, we know that its biggest fatal injury is its internal components, especially the circuit board with precise structure, which has relatively poor resistance to water vapor. Once the electronic equipment is flooded or damp, it will cause irreparable losses. , either the entire equipment is scrapped, or it needs to be disassembled for maintenance, which not only causes economic losses, but also makes the equipment unusable

[0004] Therefore, it is very necessary for electronic products to be coated with waterproof materials. However, general waterproof materials can only cover the surface of electronic products, but cannot protect the internal circuits of electronic products. At present, a completely closed material that appears on the market can Drape the inside of the product, but after the product is coated, it will completely isolate the contact of all electronic contact points, which will affect the normal function of the internal circuit of the electronic product, and cannot achieve the purpose of being fully waterproof without isolating the contact points. The current waterproof material There are still significant limitations
