[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 glass wool and a preparation method thereof, and belongs to the field of functional glass wool. The method is characterized in that graphene oxide is used as a raw material, sothat the heat energy absorbing function is improved, and the glass wool is good in energy storing effect; dopamine hydrochloride and 1-dodecanethiol are added to modify the surface of graphene, so that the glass wool cannot absorb moisture and remains hydrophobic performance in a moist environment; 2, 4-dinitrophenylhydrazine and 4-(4-nitrophenoxy)-benzoic acid are reacted to generate a compoundunder the effect of 1-propylphosphonic acid cyclic anhydride, so that the toughness and the stretching performance of the glass wool are increased, and the mechanical performance is improved; glass fibers are taken as a main body to improve the heat insulating and heat preserving performances; potassium hexatitanate whiskers are taken as fillers for improving the structure density of the glass wool, thus the impact resistance is improved, and the heat preventing effect of the glass wool is improved; an adhering additive is added to improve the combining performance, and the coordinating effectis improved. According to the glass wool, the problems of low waterproof performance, low mechanical performance and low heat preserving performance of current glass wool can be solved.

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 ...
