Embodiment Construction

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Preparation method of fireproof sound insulation temperature gas gel composite, including the following steps:

[0024] Step 1: Wrap the fiber felt with fiber cloth;

[0025] Step 2: Immerse the fiber felt in step 1 to the fiber felt in SiO 2 Sol solution;

[0026] Step 3: After sol - gel, dry and prepared the required fireproof sound insulation and gas gel composite material.

[0027] One of the fiber mat is a silicate fiber felt and a glass fiber felt; the fiber cloth is a glass fiber cloth; the fiber felt has a thickness of 3 to 100 mm; the thickness of the fiber is 0.05 to 0.65 mm.

[0028] The n-silicate, anhydrous ethanol, and deionized water and N, N-dimethylformamide were mixed in the reactor in the reactor in the reactor in molar ratio, then add 0.5 mol / L of hydrochloric acid regulation. PH to 3 ~ 4, continued to stir for 1 to 2 h. ...

Abstract

The invention discloses a fire-proof, sound-insulating and heat-insulating airgel composite material and a preparation method thereof, comprising the following steps: step 1: wrapping fiber felt with fiber cloth; step 2: immersing the fiber felt wrapped in fiber cloth in step 1 into SiO 2 In the sol solution; step 3: through sol-gel and drying, the required fire-proof, sound-insulation and thermal-insulation airgel composite material is obtained; the present invention has excellent fire resistance, and solves the problem of powder dropping of the existing airgel felt, and high temperature No obvious toxic smoke will be produced when decomposed under certain conditions, the preparation process is simple, and the requirements of safety and environmental protection are met.

Description

Technical field [0001] The present invention relates to a fire-free insulation material, and more particularly to a fire-free insulation and thermal gas gel composite material and a preparation method thereof. Background technique [0002] In the field of insulation sound insulation materials, there is currently a polystyrene foam, polyan ester foam, etc., and the combustion process produces a large amount of toxic gas; the safety is poor, while rock cotton, fiberglass, foaming cement, silicic acid Although the inorganic sheet such as aluminum fiber is excellent in fire prevention performance, the inorganic insulation board is high, the density is large. In order to achieve the ideal insulation effect, it is generally necessary to increase the thickness of the insulation layer, which not only affects the aesthetics, but also significantly increases the protective layer. thickness. [0003] In recent years, the initiated airgel is a porous network structure composed of colloidal i...
