Embodiment Construction

[0025] exist figure 1 In the shown embodiment, the present invention includes meta-aramid paper 1, temperature-resistant chemical film 2, and meta-aramid paper 1 which are in contact with each other in sequence.

[0026] In the embodiment, the meta-aramid paper 1 is composed of 1313 aramid chopped fiber, 1313 aramid precipitated fiber, and 1313 aramid pulp with an absolute mass ratio of 5:8:3; Compared with the meta-aramid paper with compound components, the overall composition of the product is simple, and it is not doped with any chemical substances that can affect the electrical insulation, so the electrical insulation and its stability are excellent.

[0027] In the embodiment, the thickness of the meta-aramid paper 1 is 100 μm; when used in electrical products, controlling the thickness of the meta-aramid paper 1 to 100 μm can not only play the protective function of flame retardant and heat insulation, but also facilitate the Forming of flame-retardant insulating compos...

Abstract

The invention discloses a flame-retardant insulated composite material and a preparation technology thereof. The flame-retardant insulated composite material comprises meta-amide paper, a temperature-resisting chemical film and meta-amide paper which are sequentially contacted. The preparation technology is characterized in that 1313 aramid chopped fiber, 1313 aramid fibrid, 1313 aramid pulp are effectively dispersed, subjected to two stages of squeezing and dewatering, drying and high-temperature plasticizing to obtain the meta-amide paper; a formed polyimide film (PI film) and or a polyethylene glycol terephthalate film (PET film) are uniformly coated with a layer of half-curing high-temperature epoxy glue, and then disposed on a high pressure compounding machine for composite forming, so as to obtain the temperature-resisting chemical film; and the temperature-resisting chemical film is disposed between two layers of the meta-amide paper, then coating and high-temperature gapless composite treatment are carried out, so as to obtain the flame-retardant insulated composite material. The flame-retardant insulated composite material has strong high temperature resistance performance and flame retardation performance for high voltages of different frequencies at 220 DEG C to 400 DEG C, so that the survivability of various electrical products can be ensured.

Description

technical field [0001] The invention relates to the field of materials, in particular to a flame-retardant insulating composite material and a preparation process thereof. Background technique [0002] At present, with regard to insulating and flame-retardant materials, the prior patent No. 200920087841.5 discloses a composite structural insulating material, which is made of three layers of materials with high-strength insulating effects, and a layer of temperature-resistant film material There is no gap between the upper and lower layers of silicone rubber. [0003] At present, with regard to this patent, the known technical structures are silicone rubber and temperature-resistant membranous materials. This technology cannot continuously and effectively guarantee the flame retardancy and high temperature resistance characteristics under the high temperature condition of 220 to 400 degrees Celsius, so as to achieve the required electrical performance indicators.
