Abstract

The present invention relates to a continuous manufacturing method for a vacuum insulation material. The method includes a first step of putting a porous insulation material into an inner envelope having air permeability, three sides thereof being closed and one side thereof being open, and then sealing the inner envelope; a second step of flattening an upper broad side of the inner envelope; a third step of compressing the inner envelope flattened in the second step; a fourth step of sealing all sides of the inner envelope compressed in the third step, except for one side, with an outer envelope material having a shielding property, and packaging the sealed inner envelope; and a fifth step of sealing the one side of the inner envelope not sealed in the third step by putting the inner envelope sealed in the fourth step into a vacuum chamber and performing a vacuum operation to obtain a predetermined pressure.

Description

technical field [0001] The present invention relates to a continuous manufacturing method of an outer wrapping material having shielding properties and a vacuum heat insulating material having a predetermined vacuum pressure therein. More particularly, the present invention relates to a continuous manufacturing method of a vacuum heat insulating material, which simplifies the manufacturing process and improves productivity using the continuous production, thus being economical and having high-quality properties. Background technique [0002] In general, vacuum insulation is a thermal insulation material which has a particularly low thermal conductivity and is surrounded on all sides by an outer wrapping material with high gas and vapor protection, in which vacuum An inorganic or organic open porous core is arranged on the insulating material. [0003] The inner core is mainly composed of glass fiber as inorganic fiber or synthetic silica as porous inorganic powder. [0004...
