Problems solved by technology

Among them, perfluorocyclic ether diluents are not easy to absorb water, but their preparation is difficult. They are mainly by-products in the production process of perfluorooctanoic acid. Due to the restriction of the perfluorooctanoic acid industry, the output is difficult to meet the market demand, and the procurement source is limited.
HFP trimer diluent is also not easy to absorb water, but due to the existence of active end groups, acid backlash is prone to occur during storage, and there is a certain corrosion on the pipeline of spraying equipment
Hydrofluoroether diluents are commonly used anti-fingerprint thinners. However, although the cost of hydrofluoroether diluents such as HFE347 and HFE374 is controllable, they are easy to absorb water, and long-term use will lead to anti-fingerprint agents. The main agent fails; HFE7100, HFE7200 and other hydrofluoroether diluents, which are used in the field of anti-fingerprint agents, have excellent comprehensive performance, but the products produced by foreign companies are expensive, and the price is hundreds of thousands of yuan per ton. unbearable

Abstract

The invention discloses a compound diluent for an anti-fingerprint agent, which is prepared from the following substances in parts by weight: 10 to 95 parts of hydrofluoroether solvents, 5 to 90 parts of 1,3-bis(trifluoromethyl)benzene and 0.0001 to 0.01 part of alkoxy silane. The compound diluent has the advantages of excellent performance, low cost and good long-term stability.

Description

Technical field [0001] The present invention belongs to the field of anti-fingerprint antifouling coating, and is specifically involved in a compound diluent for anti-fingerprints. Background technique [0002] In recent years, the touch panel of electronic products is easy to use by exposed states, skin fat, sweat and cosmetics. Therefore, in order to improve the appearance and identification, the technical requirements of the fingerprint are not easy to attach to the display surface, which is easy to remove the soil, not only to impart a good waterproof and anti-fouling layer on the surface of the touch panel, but also when wiping The surface is not easy to cause damage, with good wear resistance, and thus often need to spray anti-fingerprints on the surface of the touch screen. The anti-fingerprints mainly include two parts: the main agent and diluent. The diluent must not be burning and non-toxic, suitable for use in a dust-free workshop. The main role of the diluent has two:...
