Nickel-free hole sealing agent for aluminum-substrate laptop shell and processing technology of nickel-free hole sealing agent

Abstract

The invention discloses a nickel-free hole sealing agent for an aluminum-substrate laptop shell and relates to the technical field of laptop shell machining. The nickel-free hole sealing agent is prepared from the following raw materials comprising 6-8 parts of sodium oleate, 2-4 parts of salicylic acid, 2-4 parts of polyvinylpyrrolidone, 2-4 parts of silver diammine fluoride, 1-3 parts of sorbitol, 5-7 parts of nano crystalline cellulose, 2-4 parts of nano aluminum oxide, 2-4 parts of lithium silicate, 3-5 parts of sodium tripolyphosphate, 5-7 parts of sodium pyrophosphate, 5-7 parts of sodium metaphosphate, 2-4 parts of ethylene glycol, 6-8 parts of glycerol and 8-10 parts of an assistant. The nickel-free hole sealing agent for the aluminum-substrate laptop shell has the beneficial effects that the formula is reasonable, a processing technology is scientific and reasonable, the prepared hole sealing agent is remarkable in effect and is directly applied to the aluminum-substrate laptop shell, thus, the effect that micropores generated in the aluminum-substrate laptop shell during follow-up finish machining are sufficiently sealed can be ensured, disengagement is not prone to occurring, and the actual activity and the corresponding quality of the aluminum-substrate laptop shell are guaranteed.

Description

Technical field [0001] The invention relates to the technical field of notebook shell processing, in particular to a nickel-free hole sealing agent for aluminum base notebook shells and a processing technology thereof. Background technique [0002] A notebook computer, also known as a notebook, hand-held or laptop computer, is a small, portable personal computer. The weight of a laptop usually weighs 1-3 kilograms, and its development trend is to become smaller and lighter, while the function is getting more and more powerful, like the Netbook, which is commonly known as the netbook. The difference lies in its portability. [0003] As people’s living standards are gradually improving, and based on the gradual improvement of the information age, the number of notebook computers in the market is also increasing. Therefore, high-quality notebook computers are also a necessary technology for research and development by companies today. The intuitive texture of notebook computers is I...

[0003] Due to the gradual improvement of people's living standards and the gradual improvement of the information age, the market for notebook computers is also increasing. Therefore, high-quality notebook computers are also a necessary technology for various companies to compete for research and development. The intuitive texture of notebook computers is It is shown on the shell, and due to the gradual improvement of people's quality requirements, the use of different materials for shell processing is one of the main factors to improve the quality of shell parts. The use of aluminum substrates for notebook shell production is currently a more popular processing method One, because the texture and aesthetics of the aluminum substrate material are relatively high-quality at the current stage, the market retention rate is very large. In the actual follow-up finishing process of the notebook case made of the aluminum substrate, nickel-free sealing is involved. process, so as to improve product quality, the main purpose of nickel-free sealing is to seal the tiny gaps on the surface of the aluminum substrate after oxidation treatment, to ensure the smoothness and flatness of the panel, and to ensure its actual high corrosion resistance, but at present As far as the actual sealing agent is concerned, the effect of nickel-free sealing agent for sealing is not obvious in actual use, which affects the actual sealing effect
