Problems solved by technology

However, they all have the following deficiencies: (1) The thermal conductivity is not low enough, resulting in a large thickness of the insulation layer, which brings difficulties to the production of the mold and is not conducive to construction; (2) The compressive strength is low and easy to damage; (3) ) The closed cell rate cannot reach 100%, and there must be a reliable waterproof protective layer on the outside

Embodiment 1

[0027] Brush a layer of release agent evenly on the inner wall of the mold; pre-bond a 7mm thick silicone rubber block on the inner and outer surfaces of the 7mm thick vacuum insulation core material and place it accurately in the center of the mold; put the AB component of the polycondensation silicone rubber Stir and mix evenly with a ratio of 20:1 to prepare pink liquid silicone rubber; slowly pour the evenly mixed liquid silicone rubber into the mold, close the mold and compact it, and after curing at room temperature for 24 hours, remove the mold and remove the board, trim the corners Obtain a 21mm thick pink deformable composite insulation board.

Embodiment 2

[0029] Brush a layer of release agent evenly on the inner wall of the mold; pre-bond a 5mm thick silicone rubber block on the inner and outer surfaces of the vacuum insulation panel wrapped with 8mm thick aluminum foil and place it accurately in the center of the mold; put the AB of polycondensation silicone rubber The components are uniformly stirred and mixed at a ratio of 30:1 to prepare blue liquid silicone rubber; slowly pour the uniformly mixed liquid silicone rubber into the mold, close the mold and compact it, and after curing at room temperature for 18 hours, remove the mold and take the plate. Trim the corners to get 18mm thick blue deformable composite insulation board.

Embodiment 3

[0031] Apply a layer of release agent evenly on the inner wall of the mold; pre-bond a 3mm thick silicone rubber block on the inner and outer surfaces of the 8mm thick vacuum insulation panel and place it accurately in the center of the mold; put the AB component of the addition silicone rubber in Stir and mix evenly with a ratio of 10:1 to prepare white liquid silicone rubber; slowly pour the uniformly mixed liquid silicone rubber into the mold, close the mold and compact it, heat to 80°C for 5 hours, and then take out the plate after cooling and demoulding. Trim the corners to get a 14mm thick white deformable composite insulation board.

Abstract

The invention discloses a deformable composite insulation board and a production method of the deformable composite insulation board. The deformable composite insulation board is characterized by comprising a vacuum insulation core material and a polymer coated outside the vacuum insulation core material. The polymer comprises silicone rubber, extruded polystyrene foam plastic (XPS), polystyrene foam plastic (EPS) with a closed pore structure, phenolic foam and the like. Room temperature vulcanized silicone rubber is used as a surface material and easy to form and simple in the production process when compounded with a vacuum insulation board, and the temperature can be moderately improved while forming according to actual situations to reduce the curing time. The heat conductivity coefficient of an insulating layer material of the deformable composite insulation board is much lower than that of the existing insulation material, so that the thickness of an insulating layer can be reduced on the premise of ensuring the same insulation effect to avoid pipeline load increase due to uneven temperature of a pipeline so as to prolong the service life of the pipeline; meanwhile, the number of submarine crude oil heating points required to be set by an oil pipeline which only uses polyurethane as the insulating layer is greatly reduced, then the energy consumption is reduced, and the working procedures are simplified.

Description

technical field [0001] The invention relates to a composite thermal insulation board and a manufacturing method thereof, in particular to a deformable composite thermal insulation board and a manufacturing method thereof. Background technique [0002] With the increasing scope of offshore oil and gas exploitation, the continuous growth of consumption demand for clean energy represented by natural gas in various countries around the world, and the continuous improvement of urban heating systems, the society is demanding various pipelines such as oil pipelines, natural gas pipelines, and urban heat pipelines. The demand for it is increasing, and its requirements, especially the requirements for pipeline insulation materials, are becoming more and more stringent. [0003] Daqing Oilfield Co., Ltd. disclosed a low-temperature high-strength fluorine-free polyurethane foam insulation material in the Chinese invention patent application number 200910204969.X. The invention uses a ...
