Embodiment

[0034] A thermal insulation composition, the raw material composition is as follows:

[0035] The proportion of vitrified microbeads in the insulation material is 10-65 wt%, preferably 20-65 wt%. The vitrified microbeads used in the present invention are intuitively micro-circular particles, have a reflective continuous vitrified smooth outer surface, have obvious capillary adsorption and compressive strength, have high strength, low water absorption, high strength, and mixing. Good and easy to disperse. In the present invention, the particle size of the vitrified microbeads is preferably 15-100 mesh.

[0036] Asbestos, the proportion of the thermal insulation material is 10-50wt%, preferably 10-45wt%. In the present invention, it is preferably serpentine or Qi cotton. Serpentine asbestos, also known as serpentine asbestos, is also called chrysotile asbestos. It is a variant of serpentine and is a magnesium silicate mineral. The fibers of serpentine asbestos are rolled up in a ...

Abstract

The invention discloses a heat insulation composition with a heat insulation effect. The problem that the volume weight of the heat preservation composition is large when the heat insulation effect isimproved in the prior art is solved. The heat insulation composition comprises 10-65 wt% of vitrified microbeads, 10-50 wt% of asbestos, 1-20 wt% of aluminum silicate wool, 5-20 wt% of bentonite, 1-10 wt% of glass fibers and 1-10 wt% of a penetrant. The heat insulation composition has the advantages of excellent heat insulation performance, low volume weight, reduction of the thickness by 50% orabove under a condition that the surface temperature is same to that of the aluminum silicate wool, and remarkable energy-saving effect due to great reduction of the heat dissipation area, so the adiabatic temperature range is greatly expanded, and the working temperature range can reach -40-1000 DEG C.

Description

Technical field [0001] The invention relates to the field of thermal insulation materials, in particular to the technology and industrial upgrading of a thermal insulation composition. Background technique [0002] Traditional thermal insulation materials are mainly based on increasing the porosity of the gas phase and reducing the thermal conductivity and conductivity. Among them, fiber insulation materials must have a thicker coating to increase convective heat transfer and radiation heat transfer in the use environment; profile-type inorganic insulation materials must be assembled and constructed, and there are many joints, heat leakage, and waterproofing. Poor performance, high loss rate, non-reusable and other defects; porous structure thermal insulation material is a new type of lightweight thermal insulation and fireproof material containing a large number of closed pores, usually ceramic or expanded perlite as aggregate, and then through and inorganic cementing material ...
