Abstract

The invention belongs to the field of paint, and particularly relates to single-coating PU (polyurethane) paint with high wear resistance and high hardness and a preparation method thereof. The single-coating PU paint comprises an A-component binder, paint and a B-component curing agent, wherein the A-component binder consists of the following components in percentage by mass: 4-6% of nanoscale PTFE (polytetrafluoroethylene) wax, 10-15% of wear-resistant ceramic micro powder, 55-70% of PU resin prepared from a special group and multiple reaction groups, 10-15% of cellulose acetate butyrate and 0.2-0.5% of leveling agent; the paint comprises aluminum paste, butyl acetate and color paste; the B-component curing agent is a PU curing agent studied by use of TMP (trimethylolpropane) polyalcohol and fluororesin. The single-coating PU paint provided by the invention has the beneficial effects that the nano technology is applied to the 3C paint industry successfully for the first time, the wear resistance and hardness are improved, the solvent resistance is greatly improved, and the wear resistance, smoothness and stain resistance of the paint are improved.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a single-coat PU coating with high wear resistance and high hardness and a preparation method thereof. Background technique [0002] Since the launch of 3C electronic products, they have been favored by consumers because of their portability and portability. In the first half of 2010, the sales volume of China's smart phone market reached 24.054 million units, exceeding the annual scale of 2009. In 2011, this The trend continues unabated. In addition, from the perspective of the global market, industry veterans predict that the market size of tablet PCs alone will reach 35 billion US dollars in 2012. The 3C market demand is also relatively stable, so the demand for coatings is growing. With the improvement of performance requirements, the paint industry has an urgent demand for new environmentally friendly, energy-saving and high-performance paints. [0003] Single-coat PU coatings are...
