Embodiment 1～ Embodiment 5

[0036] Embodiment 1~embodiment 5 provides a kind of glass wool surface treatment method, concrete operation is as follows:

[0037] Step S1: The ultra-fine glass wool raw material is impregnated with acid first, and then cleaned to obtain acid-impregnated glass wool. The acid used is 40%wt HF.

[0038] Step S2: Nano-TiO 2 Dispersed in ethanol solution, nano-TiO 2 Ultrasonic dispersion in ethanol solution to obtain 15%wt nano-TiO 2 Dispersions.

[0039] Step S3: impregnating acid-leached glass wool in nano-TiO 2 After drying in the dispersion, repeat the operation to obtain pretreated glass wool;

[0040] Step S4: impregnating the pretreated glass wool with 2%wt silane coupling agent solvent, and drying to obtain modified glass wool.

[0041] The specific reaction parameters of steps S1 to S4 are shown in Table 1.

Abstract

The invention provides glass wool for buildings and a partition plate containing the glass wool. The glass wool is prepared through the following steps: step S1, dipping a glass wool raw material with acid, and then conducting cleaning to obtain acid-leached glass wool; S2, dispersing nano-TiO2 in a solvent so as to obtain a nano-TiO2 dispersion liquid; S3, dipping the acid-leached glass wool in the nano-TiO2 dispersion liquid, and conducting drying to obtain pretreated glass wool; and S4, impregnating the pretreated glass wool with a silane coupling agent solvent, and conducting drying to obtain the modified glass wool. Compared with the prior art, the invention has the beneficial effects that the glass wool is subjected to acid corrosion to increase the hydrophilicity of the glass wool; then the glass wool is soaked in the titanium dioxide dispersion liquid, so the loading capacity of titanium dioxide is increased, and the ageing resistance of the superfine glass wool is improved; and after the nano-TiO2 is deposited, the silane coupling agent is finally used for sealing layer modification, so moisture resistance is prevented from being reduced after the glass wool is corroded in an early stage.

Description

technical field [0001] The invention belongs to the field of glass wool preparation, and in particular relates to glass wool for construction and a separator containing the glass wool. Background technique [0002] Glass wool is a commonly used sound insulation and thermal insulation material in the construction field, and the improvement of its anti-aging property is an important improvement direction. Nano-titanium dioxide is widely used to improve the anti-aging properties of materials due to its photocatalytic properties. [0003] However, in the research and development of glass wool-nanocomposites, due to the current direct impregnation method, the amount of doping is limited, resulting in restrictions on the research and development of composite materials. Contents of the invention [0004] In order to solve the above-mentioned technical solution, the present invention provides glass wool for construction and a separator containing the glass wool. [0005] The spe...
