Fingerprint-resistant liquid and fingerprint cold-resistant hard roll thereof

Abstract

The invention provides a fingerprint-resistant liquid and a fingerprint-resistant cold hard roll thereof. The fingerprint-resistant liquid comprises 30-70% of resin, 0.1-5% of inorganic salt, 0.1-1% of nano silicon dioxide, 1-4% of single crystal solid nano silicon dioxide fibers, 0.1-1% of nano copper particles, 0.1-0.5% of a silane coupling agent, 0.1-5% of a surfactant and the balance of a solvent. The preparation method of the fingerprint-resistant cold hard roll comprises the following steps: 1) fully mixing resin, nano silicon dioxide, nano silicon dioxide fibers, nano copper particles, a surfactant, inorganic salt, a silane coupling agent and a solvent, and carrying out ball milling for 24 hours to obtain a fingerprint-resistant solution; 2) rolling the ultrathin hot-rolled coil by 10-40% of deformation to obtain a non-galvanized cold hard coil with the thickness of 0.5-3mm; (3) coating the fingerprint-resistant liquid on the surface of the cold hard coil through a coil bar coating roller; and (4) the coated cold hard roll steel plate is fed into a curing room, and a finished product fingerprint-resistant cold hard roll is obtained after curing. The fingerprint-resistant cold hard roll prepared by the invention has excellent mechanical properties, conductivity and corrosion resistance, also has antiviral property, and is suitable for further popularization and application.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a fingerprint-resistant liquid and a fingerprint-resistant chilled roll. Background technique [0002] Fingerprint-resistant sheet is a composite coated sheet obtained by fingerprint-resistant treatment on the surface of galvanized sheet. Fingerprint-resistant steel plate is the earliest material that has passed the environmental protection certification. It is named "fingerprint-resistant" because the surface is touched with clean fingers without leaving fingerprints. The surface of fingerprint-resistant steel plate is smooth, flat, and small tolerance. The research and production of fingerprint-resistant plates originated in Japan and entered commercial production in the early 1980s. Anti-fingerprint treatment was originally designed to meet the requirements of users in the field of home appliances. In the production process of home appliances, many parts are touched many times by wo...

Problems solved by technology

[0004] Due to the impact of raw materials, processes and energy consumption, the price of hot-dip galvanized anti-fingerprint boards is generally high. At present, nano-silica is generally used as the sealing agent in the preparation of anti-fingerprint liquid. There are some problems in using only silica, such as two Silicon oxide particles are only in point contact when in contact, and there are large gaps between particles, resulting in poor electrical conductivity and reduced corrosion resistance

In the selection of steel materials, the hot-dip galvanized chilled coils currently used are rolled from thicker hot-rolled coils. During the rolling process, due to the large amount of deformation, the steel plate is damaged to a certain extent, making its toughness and strength and The hardness has decreased, and annealing treatment is required to meet the performance requirements of use, and its energy consumption is high, cost is high, and efficiency is low
