NOVELTY - Electromagnetic shielding composite coating comprises 100 pts. wt. environmentally friendly epoxy resin, 10 pts. wt. barium sulfate, 50 pts. wt. deionized water, 30 pts. wt. iron oxide red, 15 pts. wt. 3-methacryloxypropyltrimethoxysilane (silane coupling agent KH-570), 15 pts. wt. silver powder, 5 pts. wt. graphene and 5 pts. wt. rose essential oil. USE - Used as electromagnetic shielding composite coating. ADVANTAGE - The coating has a multi-layer composite structure, simple preparation process and good air permeability; is economical; and avoids adding heavy metal wires or conductive fibers. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) air-permeable electromagnetic shielding heat-insulating cloth comprising a base cloth layer, an elastic air-permeable layer, a heat-insulating layer, an electromagnetic shielding composite coating, and a waterproof and wear-resistant layer stacked in sequence, where the electromagnetic shielding composite coating is formed by coating and curing the electromagnetic shielding composite coating; and (2) preparing the air-permeable electromagnetic shielding and thermal insulation cloth comprising separately preparing a base cloth layer, an elastic air-permeable layer, heat-insulating layer, electromagnetic shielding composite coating and waterproof and wear-resistant layer, binding the base fabric layer, the elastic breathable layer, the heat insulation layer, the electromagnetic shielding composite coating, and the waterproof and wear-resistant layer in turn, performing hot pressing molding, making holes connected to the outside in the elastic breathable layer, heat insulation layer, electromagnetic shielding composite coating, and waterproof and wear-resistant layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the air-permeable electromagnetic shielding heat-insulating cloth.
