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 a glass wool product 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 to 50°C, and then cooled to 10°C to 12°C to ensure that the liquid is fully reacted. Place 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, first add it into 10kg-11kg of clean water in an amount of 3% of the overall liquid proportion for dilution, 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 ° C ~ 1250 ° C, and the melting is carried out uniformly. After melting, it is transported to the fiber forming machine, and the temperature of the stream is k...

Abstract

The invention relates to the technical field of production of glass wool products, in particular to an acoustic glass wool product and a preparation method thereof. The glass wool product comprises the following raw materials by mass percentage: 28%-32% of boronite, 23%-27% of magnesia. %, calcium oxide 10%-16%, potassium oxide 15%-21%, iron oxide 12%-16%, acrylic adhesive 2%-6%, modification enhancer 3%-5% and corrosion-resistant additive 1.6%- 3.2%, the rest is clear water, and the preparation method includes the following steps: S1. Fully stirring and mixing the acrylic adhesive and the modified reinforcing agent in a ratio of 1:0.5, after mixing, the temperature is naturally raised to 45 ° C ~ 50 ° C, and then Cool to 10°C to 12°C to ensure that the liquid is fully reacted, and 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. The invention can not only improve the toughness and strength of the glass wool product, but also can significantly improve the overall corrosion resistance effect.

Description

technical field [0001] 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. 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 materials in the industry. Glass wool belongs to a category of glass fibers, which is an artificial inorganic Fiber, glass wool is a cotton-like material formed by fibrillating molten glass. [0003] Although the current glass wool products can have excellent characteristics such as good molding, low bulk density, low thermal conductivity, good thermal insulation and sound absorption performance, etc., there are certain defects and deficiencies in toughness and strength, and they will be stretched or bent by external forces. In addition, for products that are outdoors for a l...
