Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pocket type heat insulating material blank,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pocket-type heat insulating material blanket and a method of manufacturing the same. More particularly, the present invention relates to a pocket-type heat insulating material blanket which is made by filling various kinds of heat insulating materials with a pocket- And a manufacturing method thereof.

Insulating materials blanket refers to a single or composite insulating material such as perlite or vermiculite particles that is made into a mattress or a sheet. It has the flexibility to bend, fold or cut. It can be applied to various products requiring insulation and various industrial applications are possible. Flexibility is possible because the thermal insulation blanket is a composite consisting of fibers and insulation. At this time, if the object to be adhered is a very high temperature or a low temperature at which the resin can not be used, a metal film can be used.

The fibers enhance the flexibility of the insulation blanket, and the insulation provides the insulation properties due to porosity. It is a core compounding technology of insulation blanket that combines the characteristics of the fiber and the characteristics of the insulation to enhance the advantages of each other and to compensate for the disadvantages.

Particularly, the conventional technology for synthesizing a heat-insulating blanket is to first gel the sol through changes in pH, temperature, catalyst, etc., and then synthesize it as a porous heat insulating material through a process such as supercritical drying It was the most common method.

In the prior art, water was used as a solvent in the early stage, but when water was used, it was easily broken by the capillary stress generated in the drying process. Therefore, although the process has been developed to dry the substrate at a low temperature of 30 ° C. through alcohol solvent substitution or CO 2 solvent replacement, there is a disadvantage in using a large-sized autoclave apparatus, There is a risk of injury.

As a recently disclosed method for manufacturing a heat insulating blanket, there is an airgel-containing blanket of Cabot Corporation of the United States (Korean Patent Publication No. 2007-0100738). A hydrophobic airgel, a fiber and at least one wetting agent are used as raw materials The present invention relates to a technique for producing a heat insulating material through a series of steps of forming an aqueous slurry, drying, and calendering. As in the conventional technology for manufacturing an airgel blanket, a high temperature is required for drying, It is difficult to manufacture a thermal insulation blanket because the manufacturing process efficiency and work efficiency are difficult due to the severe process conditions to be used. Therefore, there is a disadvantage that mass production is difficult due to a high unit price of an airgel used as a thermal insulation material. There is a problem of deterioration of heat insulation due to the outflow of the heat insulating material.

Korean Patent Laid-Open Publication No. 2010-0043815 discloses an air bubble sheet using an airgel produced by using an airgel powder as a filler in an air bubble sheet. However, this publication also discloses that by using an airgel as a filler, It is difficult to apply it to the actual insulation related industry.

As a result, the inventors of the present invention have found that, in order to solve the problems of the prior art, the present inventors have found that, as a result of a simple effort, a sheet is poured into a pocket shape and then a heat insulating material is filled to adhere the heat- The present invention has been completed.
