Embodiment

[0014] A polyimide film with high temperature resistance and high flame retardancy, made of the following raw materials by weight (kg): o-phenylenediamine 54, pyromellitic anhydride 112, N,N-dimethylacetamide 28, furfural resin 32. Nano silicon nitride 12, colemanite 8, tris(2-chloropropyl) phosphate 15, antimony trioxide 7, hexachlorocyclopentadiene 13, aluminum hypophosphite 10, melamine formaldehyde resin 16, N-phenylmaleimide 5, dimethyl biphenyl diisocyanate 3, ammonium chloride 1.5, p-hydroxybenzenesulfonic acid 1.5.

[0015] A method for preparing a high-temperature-resistant and highly flame-retardant polyimide film, comprising the following steps:

[0016] (1) Grinding the colemanite into nanoscale powders with a particle size of 30nm, then adding nano-silicon nitride and mixing evenly, then adding furfural resin, and stirring for 4min at a speed of 500r / min to obtain a heat-resistant modifier;

[0017] (2) Mix aluminum hypophosphite and antimony trioxide evenly, the...

Abstract

The invention discloses a high-temperature resistant and highly flame-retardant polyimide film and a preparation method thereof, which is prepared from the following raw materials in parts by weight: o-phenylenediamine 50-55, pyromellitic anhydride 105-115, N, N-dimethylacetamide 25-30, furfural resin 28-34, nano-silicon nitride 8-14, colemanite 5-10, tris(2-chloropropyl) phosphate 13-17, dioxygen trioxide Antimony 6‑9, Hexachlorocyclopentadiene 10‑15, Aluminum Hypophosphite 7‑11, Melamine Formaldehyde Resin 12‑18, N‑Phenylmaleimide 3‑6, Dimethylbiphenyl Diisocyanate 2 ‑5, ammonium chloride 1‑2, p-hydroxybenzenesulfonic acid 1‑2. Inorganic raw materials such as colemanite added in the present invention cooperate with organic raw materials such as furfural resin to act as heat-resistant modifiers in polyimide films, which can improve the high temperature resistance, chemical resistance and impact resistance of materials The added inorganic raw materials such as aluminum hypophosphite and organic raw materials such as hexachlorocyclopentadiene cooperate with each other, and are used as flame retardant modifiers in polyimide films, so that the prepared materials have high flame retardancy and Self-extinguishing.

Description

technical field [0001] The invention relates to a polyimide film and a preparation method thereof, in particular to a high-temperature-resistant and highly flame-retardant polyimide film and a preparation method thereof. Background technique [0002] Imide film is one of the earliest commercialized and most widely used materials in polyimide. Polyimide film has the inherent excellent properties of polyimide materials, such as heat resistance, good dimensional stability and mechanical properties, insulation, radiation resistance and chemical corrosion resistance, and is widely used in high-tech fields, especially in In the development of aerospace industry, electrical and electronic industry and information industry, polyimide film has played a very important role. However, with the rapid development of high technology, the high temperature resistance and flame retardancy of traditional polyimide film can no longer meet the existing market demand, thus limiting its applicati...
