Problems solved by technology

For hydrophilic materials, there is a certain bond between the particles and between the particles and the reinforcing fibers, and the molding material has a certain strength, but not enough
After the particles are treated with hydrophobicity, the bonding between the material composition particles and the reinforcing fiber particles is greatly reduced, the formability is worse, and the strength is reduced to a certain extent compared with hydrophilic molding materials.
[0008] 2. The hydrophobic properties of the insulation board are less stable with temperature
However, the main application of microporous insulation materials is in the high temperature field, so the current materials and processes cannot fully meet the application requirements.
[0009] 3. The processing time is long and the operation is relatively complicated
Research on microporous insulation panels with certain strength, high temperature stability and hydrophobic effect, and simple operation has not been reported yet.

preparation example Construction

[0044] The preparation method of high-strength waterproof nano-porous thermal insulation board includes the following steps:

[0045] (a) The hydrophilic microporous heat-insulating material composition is mixed at a high speed in a high-speed mixer, and then molded in a mold by a press to obtain a hydrophilic microporous heat-insulating molding material;

[0046] (b) The hydrophobic microporous thermal insulation material composition is mixed at a high speed in a high-speed mixer, and then molded in a mold by a press to obtain a hydrophobic microporous thermal insulation molding material;

[0047] (c) The room temperature curing phosphate microporous thermal insulation material surface coating composition is placed on the surface of the hydrophilic microporous thermal insulation molding material or the hydrophobic microporous thermal insulation molding material by one-component dip coating method or two-component spray coating method, It can be cured at room temperature to obtain a ...

Embodiment 1

[0070] The one-component composition is spread on a plastic film to form a one-component liquid film about 1 mm thick. Place one surface of the hydrophilic microporous thermal insulation board in Comparative Example 1 gently on the liquid film, confirm that the surface is dip-coated completely, and then perform dip-coating on the reverse side. It can be surface-dried within 30 minutes, and test evaluation is carried out after 24 hours. The results are shown in Table 5.

Embodiment 2

[0072] A two-component paint spray gun was used to spray a two-component composition prepared by mixing components A and B at a weight ratio of 1:1 on the surface of the hydrophilic microporous thermal insulation board of Comparative Example 1 placed upright. After spraying the front side, spray the back side. The board can be surface-dried within 30 minutes of spraying and used for evaluation after 24 hours. The results are shown in Table 5.

Abstract

The invention relates to a method for preparing a high strength waterproof nano microporous insulation board, and a phosphate coating cured at room temperature coats the surface of a hydrophilic or hydrophobic microporous insulation molding material by dipping or spraying, and is cured at the room temperature to obtain the high performance nano microporous insulation board. Compared with the prior art, by coating the surface of the microporous insulation molding material by dipping or spraying with the phosphate coating cured at room temperature, the strength and the stability of hydrophobic properties of the insulation board can be improved significantly, the preparation process is simplified, and the production cost is reduced.

Description

Technical field [0001] The invention relates to a preparation method of a nano-microporous thermal insulation board, in particular to a preparation method of a high-strength waterproof nano-microporous thermal insulation board. Background technique [0002] Nano-porous thermal insulation board is a high-efficiency thermal insulation material that uses nano-silica, adds appropriate additives, and is directly pressed through a special process by dry pressing. Due to its special nanoporous structure and the synergistic effect of various additives, the heat conduction, convection and radiation are suppressed to the greatest extent in different application temperature ranges, making this material much better than all other traditional insulation materials , Such as mineral wool, perlite, thermal insulation brick, calcium silicate, ceramic fiber, etc., are also superior to products such as aerogel felt. In most temperature ranges, the thermal conductivity of nanoporous thermal insulati...
