Abstract

The invention provides a soft coating for metal printing and a preparation method thereof, and the soft coating for metal printing comprises the following preparation raw materials in percentage by mass: water-based mixed resin, a coupling agent, a composite delustering agent, a dispersing agent, a curing agent, a flatting agent, a film-forming agent, a defoaming agent, a filling agent and a solvent, the composite delustering agent is prepared by compounding porous silicon dioxide, an emulsifier, polyurethane and polytetrafluoroethylene, and the mass ratio of the porous silicon dioxide to the emulsifier to the polyurethane to the polytetrafluoroethylene is (10-15): (1-8): (2-7): (1-5). By optimizing the formula of the soft paint for metal printing, the formula system is more stable, the storage and use stability of the paint are facilitated, and the dispersity of the components of the formula system can be promoted by compounding the porous silicon dioxide, the emulsifier, the polyurethane and the polytetrafluoroethylene as a composite delustering agent, so that a coating film is more uniform and has a soft hand feeling; the wear resistance, the scratch resistance and the weather resistance are excellent.

Description

technical field [0001] The invention relates to the field of coating preparation, in particular to a soft-touch coating for iron printing and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, in the automotive industry, low-end automotive interior parts cannot be wrapped in leather due to cost issues, and a large number of imitation leather decorations will also bring environmental protection problems; the use of a large number of rigid plastics is cheap, but The feel is relatively poor, giving people a strong sense of low-end decoration. Therefore, some car manufacturers will spray elastic paint on the dashboard and other positions to make it feel like a leather. The soft-touch coating for printed iron has a rubber-like texture and a velvet-like touch, and is soft to the touch. It is more and more widely used in switch panels, high-end beauty appliances, computer cases and other products made of aluminum or stain...
