Problems solved by technology

[0003] Although the current glass wool products can have excellent characteristics such as good molding, low bulk density, low thermal conductivity, heat preservation and heat insulation, and good sound absorption performance, there are certain defects and deficiencies in toughness and strength, and they will be stretched or bent by external forces. The impact caused by the fracture, and for products that have been outdoors for a long time, its corrosion resistance has also become a major consideration for glass wool products

preparation example Construction

[0025] A preparation method of glass wool products for acoustics, comprising the following steps:

[0026] S1. Fully stir and mix the acrylic adhesive and the modified reinforcing agent at a ratio of 1:0.5. After mixing, the temperature is naturally raised to 45°C-50°C, and then cooled to 10°C-12°C to ensure that the liquid is fully reacted. Leave it for 3 to 4 hours, then continue to add 15kg to 16kg of modified reinforcing agent, and react for 10 to 12 minutes;

[0027] S2. Before adding the anti-corrosion additive, add it into 10kg-11kg of clean water for dilution according to the proportion of 3% of the whole liquid, and after it is fully uniform, put it into the liquid and stir for 2-3 hours for mixing;

[0028] S3. After the raw materials are put in according to the formula, the melting temperature is 1150℃~1250℃, and they are uniformly melted. After melting, they are transported to the fiber forming machine. The temperature of the stream is kept at 1130±10℃. Fiber, aft...

Abstract

The invention relates to the technical field of glass wool product production, in particular to an acoustic glass wool product and a preparation method thereof. The glass wool product is prepared from the following raw materials in percentage by mass: 28%-32% of boronite, 23%-27% of magnesium stone, 10%-16% of calcium oxide, 15%-21% of potassium oxide, 12%-16% of ferric oxide, 2%-6% of an acrylic adhesive, 3%-5% of a modified reinforcing agent, 1.6%-3.2% of a corrosion-resistant additive and the balance of clean water. The preparation method comprises the following steps: S1, fully stirring and uniformly mixing the acrylic adhesive and the modified reinforcing agent according to a ratio of 1:0.5, naturally heating to 45-50 DEG C, then cooling to 10-12 DEG C, ensuring that the liquid fully reacts, performing standing for 3-4 hours, continuously adding 15kg-16kg of the modified reinforcing agent, and performing reaction for 10-12 minutes. According to the invention, not only can the toughness strength of the glass wool product be improved, but also the overall corrosion-resistant effect can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of glass wool product production, in particular to a glass wool product for acoustics and a preparation method thereof. Background technique [0002] In the field of acoustics, in order to play the role of thermal insulation, sound absorption and noise reduction, and safety protection, glass wool acoustic panels have become the most common material in this industry. Glass wool belongs to a category of glass fibers and is a man-made inorganic material. Fiber, glass wool is a material made of molten glass fibrillated into cotton. [0003] Although the current glass wool products can have excellent characteristics such as good molding, low bulk density, low thermal conductivity, heat preservation and heat insulation, and good sound absorption performance, there are certain defects and deficiencies in toughness and strength, and they will be stretched or bent by external forces. The influence of glass wool can ...
