Abstract
The utility model provides a multi-layer composite heat insulating material which is formed by a plurality of layers of reflecting screens and a plurality of layers of heat insulating paper in a staggered and overlapped mode. The reflecting screens and the heat insulating paper are sewed together through sewing threads. The lengths of stitches of the sewing threads are 2cm to 3cm. The thickness of the positions, where a needle of the sewing threads is threaded, of the composite heat insulating material is larger than a half of the thickness of other positions of the composite heat insulating material. According to the improvement of the sewing structure of the multi-layer heat insulating material, the heat insulation requirements of a storage tank of cryogenic liquid can be met in the thickness, the sewing stitches are long and fewer, the thickness of the positions where the needle is threaded is close to the thickness of the other positions, and therefore heat preservation performance and heat insulating performance are greatly improved.
Description
Technical field
The utility model relates to thermal-protective material, especially relates to a kind of MULTILAYER COMPOSITE thermoinsulation material.
Background technique
The general storage tank that is used for storing cryogenic liquid is that multilayer insulant is wrapped in container inner liner, through bonding, tie up after the upper outside courage of cover form.Multilayer insulant normally is comprised of reflecting screen and Spacer.But the materials such as reflecting screen aluminium, copper, such as aluminium foil or aluminium plating terylene film, and Spacer is selected the sheathing papers such as glass fiber paper, plant fiber paper.
At present, a kind of multilayer insulant of using on the cryogenic liquid storage tank is mainly sewed up by thermal-protective material Spacer and metal foil (reflecting screen) combination and forms, but the stitch that traditional thermal-protective material sews up is very short very close, and the thickness at the place of threading a needle is well below other local thickness, reduce the heat-shielding performance of multilayer insulation material, can not satisfy the heat insulation requirement of low temperature area in the large size.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of MULTILAYER COMPOSITE thermoinsulation material, can satisfy at thickness the heat insulation requirement of the storage tank of cryogenic liquid, and the stitch that sews up is long and lack, and the place's of threading a needle thickness has improved thermal and insulating performance greatly near the thickness of other parts.
For achieving the above object, the utility model proposes provides a kind of MULTILAYER COMPOSITE thermoinsulation material, be formed by stacking by some layers of reflecting screen and sheathing paper are staggered, reflecting screen and sheathing paper are seamed in together by sewing thread, the stitch lengths of described sewing thread is 2cm～30cm, described composite insulation material sewing thread thread a needle the place thickness greater than 1/2 of other parts thickness.
As preferably, the line space of described sewing thread is 5～20cm.
As preferably, the line space of described sewing thread is 10cm.
As preferably, the stitch lengths of described sewing thread is 5cm.
As preferably, the thickness of described composite insulation material at the sewing thread place of threading a needle is 80%～100% of other parts thickness.
As preferably, described reflecting screen adopts aluminium foil.
The beneficial effects of the utility model: by multilayer insulant being sewed up the improvement of structure, can satisfy at thickness the heat insulation requirement of the storage tank of cryogenic liquid, and the stitch that sews up is long and lack, and the place's of threading a needle thickness has improved thermal and insulating performance greatly near the thickness of other parts.
