A kind of insulating coating on the surface of ultra-thin silicon steel and its preparation method

The invention belongs to the technical field of coating compositions, in particular to an ultra-thin silicon steel surface insulating coating and a preparation method thereof. The insulating coating provided by the invention is prepared from the following components: 65 to 85 parts of magnesium dihydrogen phosphate, 0.1 to 1.5 parts of insulating inorganic nanoparticles, 2 to 15 parts of silica sol, 2 to 4 parts of boric acid and 1 to 32.9 parts of deionized water. The coating formed by synergistic effects of all the components has excellent adhesion property to the surface of a bare steel sheet of ultra-thin silicon steel, and meanwhile, the insulation performance is ensured. The insulating coating provided by the invention is also prepared from 0.01 to 5 parts by weight of organic resin;by the addition of the organic resin, the adhesion of the ultra-thin silicon steel surface coating can be improved and subsequent high temperature sintering can be resisted, so that the ultra-thin silicon steel with the coating can be suitable for preparing a roll core of a saturation reactor, and further complex operating conditions such as strong vibration and high temperature rise of high pressure anode saturation reactors are met.

In-cell liquid crystal panel and liquid crystal display device

The present invention provides an in-cell liquid crystal panel having: an in-cell liquid crystal cell that is provided with a liquid crystal layer comprising liquid crystal molecules which are homogeneously oriented when no electric field is present, a first transparent substrate and a second transparent substrate sandwiching the liquid crystal layer on both sides, and a touch sensing electrode portion related to touch sensor and touch-driven functions between the first transparent substrate and the second transparent substrate; and a polarizing film with added adhesive layer that is disposed,via a first adhesive layer and without interposing a conductive layer, to the first transparent substrate side on the viewing side of the in-cell liquid crystal cell. The polarizing film with added adhesive layer is provided with a surface treatment layer, a first polarizing film, and the first adhesive layer in this order. The surface treatment layer includes at least one of any antistatic agentselected from ionic surfactants, conductive microparticles, and conductive polymers. In the in-cell liquid crystal panel, the antistatic function is satisfactory and it is possible to satisfy touch sensor sensitivity as well as conduction reliability and durability in humid environments.
