preparation example Construction

[0019] In the second aspect, the present invention provides the method for preparing the thermal insulation board described in the first aspect, comprising the following steps: weighing silica airgel, ceramic fiber, solvent, dispersant, and adhesive according to the proportion for use; first Put the solvent and dispersant into the reaction kettle and stir to fully disperse the dispersant in the solvent, then add silica airgel, stir evenly at room temperature, then add adhesive and ceramic fiber in turn, and stir evenly at room temperature, That is, the slurry is prepared;

[0020] Pour the prepared slurry into the film cavity, press it with an air press, and then solidify at 60-300°C to obtain a blank. After scraping the bottom of the blank, turning it over, setting its thickness, and polishing, the thermal insulation board is obtained. .

[0021] Preferably, the stirring speed is 500-1500r / min; the time is 0.5-2h.

Embodiment 1

[0024] Take by weight: 3 parts of silica airgel, 50 parts of ceramic fibers with a length of 10mm, 40 parts of ethanol, 1 part of dispersant, 100 parts of adhesive (acrylic adhesive) for subsequent use; Put ethanol and dispersant into the reaction kettle and stir to make the dispersant fully dispersed in ethanol, then add silica airgel, stir evenly at room temperature, then add adhesive and ceramic fiber in turn, and stir evenly at room temperature, that is Prepare slurry;

[0025] The prepared slurry is poured into the membrane cavity, compressed by an air press, and then solidified at 150°C to obtain a blank. After scraping the bottom of the blank, turning it over, sizing it, and polishing it, the thermal insulation board is obtained.

Embodiment 2

[0027] Take by weight: 15 parts of silica airgel, 40 parts of ceramic fiber with a length of 1 mm, 150 parts of isooctane, 3 parts of dispersant, 180 parts of adhesive (acrylic adhesive) for standby; First put isooctane and dispersant into the reaction kettle and stir to make the dispersant fully dispersed in isooctane, then add silica airgel, stir evenly at room temperature, then add adhesive and ceramic fiber in sequence, Stir evenly at room temperature to obtain a slurry;

[0028] The prepared slurry is poured into the membrane cavity, compressed by an air press, and then solidified at 60°C to obtain a blank. After scraping the bottom of the blank, turning it over, sizing it, and polishing it, the thermal insulation board is obtained.

Abstract

The invention discloses a heat-preservation thermal-insulating plate which comprises the following raw materials in parts by weight: 3-50 parts of silicon dioxide aerogel, 3-50 parts of ceramic fiber, 30-150 parts of a solvent, 1-10 parts of a dispersing agent and 100-200 parts of an adhesive. The heat-preservation thermal-insulating plate has the advantages that on one hand, by virtue of physical properties of the silicon dioxide aerogel, the raw materials such as the ceramic fiber are added to prepare the heat-preservation thermal-insulating plate, so that the prepared heat-preservation thermal-insulating plate is high in pressure resistance, high in breaking strength, excellent in fire resistance and high in durability; on the other hand, the heat-preservation thermal-insulating plate is prepared from the raw materials by using a simple preparation method, on-scale production can be facilitated, the thermal-insulating property of the heat-preservation thermal-insulating plate is excellent, that is, is less than or equal to 22 Mw / m*K, and thus the prepared heat-preservation thermal-insulating plate has the characteristics of being high in fire resistance and hydrophobicity, light in weight and high in flexibility and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation, in particular to a thermal insulation board and a preparation method thereof. Background technique [0002] At present, due to the increasing attention to the fire protection of thermal insulation materials, the development of domestic thermal insulation materials is becoming more and more rapid. And house construction, especially the house construction in the alpine region, a large amount of heat in the house is dissipated through the roof and the wall. Therefore, it is necessary to pave insulation boards on the roof and outer walls to play the role of thermal insulation and energy saving. A good thermal insulation board has good compressive strength and flexural strength, excellent fire resistance and high durability. However, the existing thermal insulation board has poor thermal insulation performance, complex construction steps, and large application limitations. Today, when bui...
