Problems solved by technology

[0002] Existing thermal insulation materials are mainly divided into two types: organic and inorganic. Organic thermal insulation materials have poor heat resistance and are not suitable for use under high temperature conditions.
Inorganic hard insulation materials have poor flexibility, inconvenient construction and are easy to pulverize; soft insulation materials are easy to deform and collapse, the service temperature is not high and the service life is not long

preparation example Construction

[0021] 1. Preparation of inorganic modified colloid:

[0022] Aluminum oxide, aluminum phosphate, polyvinyl alcohol, and water are weighed according to the mass ratio of 20:2:0.5:77.5, stirred and reacted to form a modified mixed colloid.

[0023] 2. Vitrified microbeads mixed with modified titanium dioxide:

[0024] Coarsely sieve the vitrified microbeads, pass through a 70-100 mesh sieve, and place the coarsely screened particles; add water to the modified titanium dioxide nanoparticles and mix evenly, and stand for 6-8 hours.

[0025] 3. Inorganic fiber pretreatment:

[0026] Put the inorganic fiber in the wind disperser and fully disperse it.

[0027] 4. Beating and mixing:

[0028] Mix the modified mixed colloid aqueous solution with the vitrified microbeads and the static modified titanium dioxide and add it to the mixer, then add the inorganic fiber and stir for 1 hour, add the modified titanium dioxide nanoparticle aqueous solution, stir for 10 minutes, add sepiolit...

Abstract

The invention provides a multi-coelomopore inorganic composite rollable heat-insulating material. The heat-insulating material is obtained through preparation of inorganic modified colloid, mixing of vitrified microbeads and modified titanium dioxide, pretreatment of inorganic fiber, pulping and mixing, standing for defoaming, forming and drying. The heat-insulating material is rollable, resistant to high temperature, simple and convenient to construct, high in binding strength and flexibility and suitable for serving as a heat-insulating roll in use.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a multi-cavity inorganic composite curlable thermal insulation material. Background technique [0002] Existing thermal insulation materials are mainly divided into two types: organic and inorganic. Organic thermal insulation materials have poor heat resistance and are not suitable for use under high temperature conditions. Inorganic hard insulation materials have poor flexibility, are inconvenient to construct and are easy to pulverize; soft insulation materials are easy to deform and collapse, and the service temperature is not high and the service life is not long. The thermal insulation industry urgently needs new thermal insulation materials with good performance, high temperature resistance and green environmental protection. Contents of the invention [0003] In order to overcome the shortcomings of traditional thermal insulation materials, the present invent...
