[0024] The preparation method of thermal insulation additive is:

[0025] (1) Take hydrochloric acid with a mass fraction of 35% and place it in a closed container, and volatilize it to obtain hydrogen chloride gas. Put graphene oxide in the hydrogen chloride gas and let it stand at 25~30°C for 4~7h. 1~5:2~6, add hydriodic acid aqueous solution with a mass fraction of 10%, let it stand for 10~15h, filter, take the filter cake and add it to absolute ethanol according to the mass ratio of 2~5:10~20, stir and mix for 3~ 8 days, dry, then pass through argon protection, anneal at 500~600°C for 1~3h, cool to room temperature, ball mill for 5~10min, and get the ball milled product;

[0026] (2) Take Tris-HCl buffer solution with pH 8.5 and mix it with absolute ethanol at a mass ratio of 3~6:1~3 to obtain a mixed solution. Take dopamine hydrochloride at a mass ratio of 3~6:1~3:20 Add dodecanethiol and mixed solution at ~30°C, stir and mix for 30~50min at 30~35°C to obtain the stirred...

Abstract

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.

Description

technical field [0001] The invention relates to the field of glass wool, in particular to glass wool and a preparation method thereof. Background technique [0002] Glass wool is made of centrifugal glass wool felt, which is processed by Owens Corning (OC)'s unique patented centrifugal technology, which is made of molten glass fiber and added with an environmentally friendly formula binder based on thermosetting resin. It is an elastic mat made of glass fibers with a diameter of only a few microns, and can be combined online with different moisture-proof veneers according to the requirements of use. It has a large number of tiny air pores, which make it play the role of thermal insulation, sound absorption and noise reduction, and safety protection. It is the best material for thermal insulation, sound absorption and noise reduction of steel structure buildings. Glass wool belongs to a category of glass fibers and is a man-made inorganic fiber. Natural ores such as quartz ...
