The invention discloses a glass wool and a preparation method thereof, belonging to the field of functional glass wool. The present invention uses graphene oxide as a raw material to increase heat absorption efficiency, so that glass wool has a better energy storage effect, and adds dopamine hydrochloride and dodecanethiol to modify the surface of graphene oxide, so that glass wool can be used in a humid environment Does not absorb moisture and maintains hydrophobic properties; 2,4-dinitrophenylhydrazine and 4-(4-nitrophenoxy)-benzoic acid are used to generate compounds under the action of 1-propyl phosphoric acid cyclic anhydride, which increases the glass wool The toughness and tensile properties improve the mechanical properties; the glass fiber is used as the main body to increase the thermal insulation performance, and the potassium hexatitanate whiskers are used as fillers to increase the structural compactness of the glass wool, improve the impact resistance, and increase the glass wool. Cotton's heat protection effect, increased binding performance through adhesive additives, improved synergistic effect. The invention solves the problems of poor water resistance, poor mechanical performance and thermal insulation of the current glass wool.

The invention relates to a metal coordination heteroatom-containing organic microporous material and its preparation and application. The organic conjugated precursor of the organic microporous material has the structural formula I or II. Preparations include: 4‑trimethylsilylethyne‑2‑bromopyridine or 5‑trimethylsilylethyne‑3‑bromopyridine, 4‑ethynyl‑2‑bromopyridine or 5‑ethynyl‑3‑bromopyridine , preparation of bis(2-bromopyridine) acetylene or bis(3-bromopyridine) acetylene, preparation of bis(2-thienpyridine) acetylene or bis(3-thienylpyridine) acetylene, preparation of organic conjugated precursor, metal coordination containing Preparation of heteroatom organic microporous materials. The organic microporous material has controllable morphology and structure, and then has different properties and functions, and can be applied to the development of new functional materials such as gas adsorption and storage, molecular separation, catalysis, and slow release of drugs.
