Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite insulation panel for construction using a super insulation material as a core material, and a continuous apparatus and method for manufacturing the same. 2. Description of the Related Art [0002]

The present invention relates to a building panel for construction, and more particularly, to a composite insulation panel for construction using a super insulation material such as a vacuum insulation panel, and a continuous manufacturing apparatus and method for continuously manufacturing the same.

These days, insulating panels are being developed with a focus on the design of the shell considering sound appearance, soundproofing effect, and flame retardant advantageous in case of fire. In recent years, insulation panel thickness has been increasing due to strengthening of energy efficiency design standards. This has caused problems such as increase in logistics cost and material cost in construction construction, increase in labor cost due to poor construction, and space efficiency in construction.

Therefore, even if the energy efficiency design standard is strengthened, it is necessary to develop a high efficiency panel which can increase the insulation effect without increasing the thickness.

Recent interest and application of vacuum insulation panels, which have excellent insulation performance and thin thickness, can be a new alternative.

However, the vacuum insulation material is excellent in the initial insulation performance, but has a high unit cost, and the vacuum is broken during assembly and construction, and after use of the panel, and the insulation performance is similar to that of general insulation.

Vacuum thermal insulation panels are completed by assembling the envelope to the vacuum insulation panel. When the vacuum insulation panel and the envelope are coupled, the thermal insulation panel breaks frequently, and the vacuum is broken even when the vacuum insulation panels are installed. Even if the vacuum insulation panel is properly constructed, if the vacuum insulation panel is used for more than three years or more than 5 years, the vacuum may be broken due to various internal and external factors, and the insulation performance may be deteriorated drastically. Which may lead to performance degradation.

Therefore, it is desired to develop an insulating panel combining the solidity of the existing insulating panel and the excellent thermal conductivity of the vacuum insulating material.

When the vacuum insulator 50 is inserted, the lower foam injection nozzle 52 injects a foaming agent between the lower surface of the vacuum insulation material 50 and the upper surface of the sheathing steel sheet 16a,
The upper foam injection nozzle 54 injects the foaming agent between the upper surface of the vacuum insulating material 50 conveyed from the downstream of the lower foam injection nozzle 52 and the lower surface of the inner steel sheet 12a to be foamed,
The side foam injection nozzle 56 injects the foaming agent to the sides of the vacuum heat insulator 50 between the endface steel sheet 10a and the sheath steel sheet 16a which are conveyed from the downstream of the upper foam injection nozzle 54, (50) is positioned at the deep part of the heat insulating panel.
In a composite prefabricated building insulation panel,
A vacuum heat insulator 50 and a foamed jacket 70 made of a urethane foam material are interposed between the inner steel plate portion 72 and the outer steel plate portion 74. A mat insulating vacuum insulator 50 is positioned at the core portion, The foamed cover material 70 of foamed material is configured to be bonded to the inner and outer steel plates 72 and 74 while covering the entire surface of the mat of the vacuum insulation material 50. Both ends of the inner and outer steel plates 72 and 74 And the other end portions of the inner and outer steel plates 72 and 74 form a composite heat insulating panel A having the bent reinforcing portion 74a formed by the bending of the edge of the steel plate, (A) having a thickness of 20 to 50 mm and a heat conduction ratio of 0.15 to 0.25 W / m ² k.
