Embodiment Construction

[0013] a. As shown in FIG. 1 : there is a slurry layer 1 between the fiber layers 2 .

[0014] The raw material composition of the slurry layer: 20 parts of rock wool, 65 parts of sepiolite, 2 parts of polyvinyl alcohol, 1.5 parts of rare earth composite adhesive, 20 parts of bentonite, 20% of hollow ceramic powder and 80% of porous ceramic particles by weight 1.5m 3 mix.

[0015] b. Slurry preparation process: mix polyvinyl alcohol, rare earth composite adhesive and bentonite, add hot water and stir to form slurry, add rock wool, sepiolite, hollow ceramic powder and porous ceramic particles to the slurry In the material, stir to mix, and reconcile with water to form a paste.

[0016] c. Manufacture of thermal insulation body: Lay a layer of fiber layer on the object that needs thermal insulation, coat the slurry on the fiber layer, and then lay a fiber layer on the slurry to form a layer of thermal insulation body, which can be laid layer by layer according to needs With c...

Abstract

The invention provides a thermal insulator for preventing heat exchange in heat working field and preparation method thereof. A pasty slurry is mixed by rockwool, sepiolite, polyvinyl alcohol, rare earth compound adhesive, bentonite and mixture of hollow ceramic powder and porous ceramics microparticles. The pasty slurry is laid between fibrous layers to form a thermal insulator. The thermal insulator of the invention has advantages of excellent ageing resistance, impact resistance, high temperature resistant and high heat insulation, can be applied widely in heat preservation environment such as boilers, kilns, heat exchangers, cold-heat transition pipeline, air-condition and refrigerated warehouse etc.

Description

technical field [0001] The invention proposes a thermal insulation body for preventing heat exchange in the field of thermal engineering and a manufacturing method thereof. Background technique [0002] In order to prevent the heat exchange of the object, a thermal insulation body made of heat insulating material is usually arranged outside the object. The heat insulation materials used are usually polymers, non-metals or structures with closed cavity structures. Such as polymer and non-metallic porous foam materials, organic and inorganic fibrous materials. It is placed on the outer surface of the object to be insulated by smearing and wrapping to form an insulator. Due to the limitation of the nature of the material used, its versatility is poor, and its high temperature resistance is poor. Especially when it is used on a high temperature furnace body, it cannot meet the technical requirements of heat preservation, resulting in large heat loss and high energy consumption...
