Abstract
Description
Technical Field
[0001] The utility model relates to a thermal insulation material, in particular to a composite thermal insulation material. Background Art
[0002] In general petrochemical manufacturing industries, pipelines are widely used to transport specific liquids. Since some of the liquids being transported are corrosive, metal pipelines are often used to transport them in order to avoid or reduce the impact of the liquid during transportation. However, metals usually have a high thermal conductivity, which is disadvantageous when the transported liquid needs to be maintained at a certain temperature. To solve this problem, the outer periphery of the metal pipeline is usually coated with insulation material.
[0003] In addition to the above functions, pipeline coating materials can also prevent or reduce the heat loss of fluid in equipment or pipelines and the energy consumption, thereby saving energy; provide process stability; and protect personnel from being injured by overcooling or overheating. Common insulation materials include: ceramic fiber wool, aerosol, rock wool and aluminum foil. In addition to heat preservation, these materials also have fire prevention, external damage prevention, corrosion resistance and other functions.
[0004] The commonly used thermal insulation aluminum foil is not only difficult to install, but is also often bent during installation, which increases the thickness of the thermal insulation material. This is disadvantageous in certain situations where space is limited. Utility Model Content

[0007] Preferably, the material of the base layer is selected from one of paper and cloth.
[0008] Preferably, the base layer is made of kraft paper.
[0009] Preferably, the material of the reinforcement layer is selected from one of glass fiber mesh, rubber and polyester fiber fabric.
[0010] Preferably, the base layer, the strengthening layer and the aluminum foil layer are combined together by hot melting and pressing.
[0011] Preferably, the laminated aluminum foil is attached to the rock wool by the base layer.
[0012] Preferably, another strengthening layer and another aluminum foil layer are sequentially arranged on the other side of the base layer of the laminated aluminum foil.
[0013] Preferably, it further comprises an aluminum foil disposed on the other side of the rock wool.
[0014] Preferably, the rock wool is a cylindrical object having an annular wall, and the annular wall has an inner side and an outer side, and the inner side encloses a channel; the laminated aluminum foil is arranged on the outer side of the rock wool.
[0015] Preferably, the rock wool is a planar object.
[0016] The beneficial effects of the utility model are:
[0017] The composite thermal insulation material provided by the utility model can provide a good coating effect during thermal insulation treatment. The reinforcing layer of the laminated aluminum foil makes the laminated aluminum foil have better strength, tensile strength and tear resistance, so that the laminated aluminum foil will not break when wrapped around the outside of pipelines or other thermal insulation materials, and has good flatness.

[0023] See also Figure 1 As shown, the composite thermal insulation material 1 provided in the first preferred embodiment of the present invention comprises: a rock wool 10 , an aluminum foil 20 and a laminated aluminum foil 30 .
[0024] The rock wool 10 in this embodiment is a cylindrical object made of rock wool, having an annular wall 12, and the annular wall 12 has an inner side 14 and an outer side 16, and the inner side 14 encloses a channel 18. The channel 18 is for a pipeline (not shown) to be accommodated therein. The aluminum foil 20 is attached to the inner side 14 of the rock wool 10, and the laminated aluminum foil 30 is attached to the outer side 16. The aluminum foil 20 is made of common aluminum foil, which will not be described in detail here. The main innovation of the utility model is the laminated aluminum foil 30, which is described as follows:
[0025] See also Figure 2 The laminated aluminum foil 30 comprises a base layer 32, two strengthening layers 34 and two aluminum foil layers 36. The two strengthening layers 34 are attached to opposite sides of the base layer 32, and the two aluminum foil layers 36 are attached to the outer sides of the two strengthening layers 34 respectively.
[0026] The base layer 32 is flexible and serves as the base of the laminated aluminum foil 30 of the first preferred embodiment of the present invention. The materials that can be used as the base layer 32 include: paper (especially kraft paper) and cloth (woven or non-woven).
[0027] The two strengthening layers 34 make the laminated aluminum foil 30 of the first preferred embodiment of the utility model have better strength, tensile strength and tear resistance, so that the laminated aluminum foil 30 will not break when wrapped on the outside of pipelines or other insulation materials, and has good flatness. The materials that can be used as the strengthening layer 34 include: glass fiber mesh, rubber, polyester fiber fabric, etc. Among them, glass fiber mesh is preferred.
[0028] The second aluminum foil layer 36 is preferably made of high temperature resistant aluminum foil.
[0029] The base layer 32, the two strengthening layers 34 and the two aluminum foil layers 36 can be combined together by hot melting and pressing to form the laminated aluminum foil 30 of the first preferred embodiment of the utility model. The laminated aluminum foil 30 has a thickness of 0.25 mm to 1.0 mm, a tensile strength of more than 50 lb / in, and a peel strength of more than 50 oz / in.
