Abstract

The invention discloses a paint with high conductivity and a preparation method and applications thereof. The conductive paint comprises following components in percentage by weight: 18 to 25% of acetone, 5 to 10% of diethyl phthalate, 15 to 20% of lutetium containing composite ceramic powder, 8 to 11% of lutetium containing alloy powder, 0.8 to 1.1% of phosphate diester, 10 to 15% of polyacrylate, and the balance being polyurethane. A surface material painted by the paint has an extremely good thermal insulation performance and a strong performance on reflecting heat and solar light. The preparation method is simple and is suitable for industrial production and the production cost is low. The paint can be painted on multiple fabrics, and the obtained fabrics can be applied to fields suchas outdoor goods, clothes, buildings, military, and the like, and are massively used in the thermal insulation field.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating with high conductivity and a preparation method and application thereof. Background technique [0002] Chinese patent document CN106634519A discloses a non-sintered conductive coating for textile surfaces and its preparation method and application. The coating components include: 8-60% of nano-silver particles, 5-60% of resin binder phase 60%, solvent 20-70%, auxiliary agent 1-15%. The preparation method comprises: adding nano-silver particles into a solvent and ultrasonically dispersing to obtain a stable suspension; adding resin binding phase and auxiliary agent into the suspension and stirring to obtain the finished product. The conductive paint of the present invention is printed on the surface of textiles by screen printing, and the conductive circuit pattern is printed on the surface of the textile; then the printed pattern is placed in a chemical treatment liqu...
