Embodiment 1

[0025] An airgel modified thermal insulation material, comprising 5-60 parts of an adhesive, 0.1-10 parts of a reinforcing agent, 0.5-60 parts of an airgel, 10-65 parts of a functional material and 10-60 parts of a liquid solvent in parts by weight share;

[0026] Wherein, by weight, it includes 32 parts of adhesive, 5 parts of reinforcing agent, 30 parts of airgel, 37 parts of functional material and 35 parts of liquid solvent;

[0027] Wherein, the adhesive includes but not limited to water glass or cement or other organic binders or mixtures thereof;

[0028] Wherein, the reinforcing agent is aluminum silicate fiber or other fibers or silicon whiskers or ceramic whiskers;

[0029] Among them, the functional material is hollow vitrified microspheres or closed-cell perlite or fly ash or polyphenylene particles;

[0030] Wherein, the liquid solvent includes but not limited to water or alcohol.

Embodiment 2

[0032] The preparation method of the airgel modified insulation board is as follows:

[0033] Step 1: using the adhesive as the base material, adding airgel, reinforcing agent and liquid solvent in sequence, and mixing after adding to obtain a mixed slurry;

[0034] Step 2: adding functional materials to the above mixed materials, and continuing to mix to obtain airgel modified thermal insulation mortar;

[0035] Step 3: drying and molding the airgel-modified thermal insulation mortar obtained in the above-mentioned step 2 to obtain an airgel-modified thermal insulation board.

[0036] In the above step 1 and step 2, the solvent can be directly added to the airgel to make a slurry first, and then other materials are added in turn. The solvent includes a co-solvent, and the co-solvent includes a surfactant. Since the aerogel is a very large volume of hydrophobic Water-based powder may be insoluble when directly added to water, so it is necessary to add a surfactant to reduce t...

Embodiment 3

[0038] The preparation method of airgel modified thermal insulation mortar is as follows:

[0039] Step 1: using the adhesive as the base material, adding airgel, reinforcing agent and liquid solvent in sequence, and mixing after adding to obtain a mixed slurry;

[0040] Step 2: Add functional materials to the above mixed materials, and continue mixing to obtain airgel modified thermal insulation mortar.

[0041] In the above step 1 and step 2, the solvent can be directly added to the airgel to make a slurry first, and then other materials are added in turn. The solvent includes a co-solvent, and the co-solvent includes a surfactant. Since the aerogel is a very large volume of hydrophobic Water-based powder may be insoluble when directly added to water, so it is necessary to add a surfactant to reduce the tension, first make a slurry, and then add other materials in turn.

Abstract

The invention discloses an aerogel modified thermal insulation material which comprises the following components in parts by weight: 5-60 parts of an adhesive, 0.1-10 part of a reinforcing agent, 0.5-60 part of aerogel, 10-65 parts of a functional material and 10-60 parts of a liquid solvent. A preparation method of the aerogel modified thermal insulation material comprises the following steps: 1,with the adhesive as a substrate material, sequentially adding the aerogel, the reinforcing agent and the liquid solvent, and conducting mixing after addition to obtain mixed slurry; 2, adding a functional material into the mixed material, and continuously conducting mixing to obtain aerogel modified thermal insulation mortar; and 3, drying and molding the aerogel modified thermal insulation mortar obtained in the step 2 to obtain the aerogel modified thermal insulation board. The aerogel modified thermal insulation material prepared by the method disclosed by the invention can replace efficient thermal insulation slurry on a building, and can be directly scraped or brushed on the building to be used as a thermal insulation material, so that the problems of low efficiency and no thermal insulation effect of the traditional mortar at present are avoided.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an airgel modified thermal insulation material. Background technique [0002] In recent years, thermal insulation materials have developed rapidly. The use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Usually thermal insulation materials are mainly based on increasing the gas phase void ratio and reducing the thermal conductivity and conductivity coefficient. In order to improve convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating, while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance, Poor water resistance, short service life and other defects, for this reason people have been seeking...
