Composite ultrathin vacuum heat preservation plate and manufacturing method thereof

Abstract

The invention discloses a composite ultrathin vacuum heat preservation plate and a manufacturing method thereof. A heat preservation cotton block (1) is filled in a block-shaped die box (2); a membrane-covered aluminum foil (3) is wrapped outside the die box (2) to form a basic plate; the basic plate is filled in a membrane coating aluminum foil box (4); glass cloth (5) is wrapped outside the membrane coating aluminum foil box (4) to form core plates; the core plates are tidily arranged on the same plane and are bonded by an adhesive to form substrates; and at least an upper layer of substrate and a lower layer of substrate are staggered, and splicing seams are bonded by the adhesive, thus forming the heat preservation plate. The heat preservation plate is provided with two vacuum layers, and is low in heat conduction coefficient and good in heat preservation effect; the core plates in the substrates are arranged in a mosaic manner and are mutually independent, so that even if one of the core plates is disabled, the heat preservation effects of other core plates can not be influenced; and the problem that the whole heat preservation plate loses the heat preservation effect after being perforated is solved, thereby ensuring that the heat preservation plate can be perforated.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a composite ultra-thin vacuum thermal insulation board and a manufacturing method. Background technique [0002] At present, a vacuum insulation board (also called VIP insulation board) has appeared in the building insulation board. It was used in the occasions with high insulation requirements such as refrigerators and aviation. With the continuous improvement of technology, it has also been used in building insulation in recent years. Industry gets used. However, due to the completely different use occasions of building insulation and refrigerators, some problems have also appeared correspondingly, such as: due to the harsh application environment, the vacuum insulation board is always in a negative pressure state, the vacuum will be lost after a long time, and the vacuum The insulation board swells due to the loss of vacuum, making the original wall surface uneven, and th...

AI Technical Summary

Problems solved by technology

However, due to the completely different use occasions of building insulation and refrigerators, some problems have also appeared correspondingly, such as: due to the harsh application environment, the vacuum insulation board is always in a negative pressure state, the vacuum will be lost after a long time, and the vacuum The insulation board swells due to the loss of vacuum, making the original wall surface uneven, and the insulation effect is lost immediately

In addition, this kind of insulation board mainly relies on vacuum to achieve the insulation effect, so it can only be made into pieces of a specified size. Due to the difference in the wall surface or windows during on-site construction, it is impossible to change the board.
