Heat-insulation cold-preservation insulation board for low-temperature storage tank and installation method thereof

Abstract

The invention relates to a heat-insulation cold-preservation insulation board for a low-temperature storage tank and an installation method of the insulation board. The insulation board comprises a high-temperature layer plate (1), an upper intermediate layer plate (2), a lower intermediate layer plate (3) and a low-temperature layer plate (4) which are sequentially arranged in layers, a stainlesssteel mesh (5) is arranged between the high-temperature layer plate (1) and the upper intermediate layer plate (2), a grid cloth (6) is arranged between the upper intermediate layer plate (2) and thelower intermediate layer plate (3), a gap for filling polyurethane is reserved between the lower intermediate layer plate (3) and the low-temperature layer plate (4), a protective skin (7) is arranged on the outer side surface of the high-temperature layer plate (1), and elastic thermal insulation materials (8) are arranged on two adjacent side surfaces of the upper intermediate layer plate (2),the lower intermediate layer plate (3) and the low-temperature layer plate (4). Compared with the prior art, the heat-insulation cold-preservation insulation board has the advantages of being excellent in heat preservation performance, wide in application range, easy and convenient to install, long in service life, excellent in installation environment and excellent in shape design.

Description

technical field [0001] The invention relates to an insulating material for the outer wall of a low-temperature storage tank, in particular to a heat-insulation and cold-preservation insulation board for a low-temperature storage tank and an installation method thereof. Background technique [0002] At present, for the insulation of some low-temperature storage tanks and fuel tanks on the market, polyurethane spray foam and pasted insulation boards are mainly used. [0003] Polyurethane foam spraying will lead to a poor working environment on site, and it is necessary to cultivate a large number of professional talents. Due to human factors, there will be high instability of site materials. In the case of shrinkage, polyurethane is prone to cracking. [0004] In the form of pasting the insulation board, although the material has been well controlled, the pasting performance will cause the problem of pasting failure due to factors such as humidity, temperature, and constructi...

AI Technical Summary

Problems solved by technology

The above-mentioned structure requires many parts when installing, and at the same time, two insulation boards are fixed at the same time through screw rods and fixed plates, so the structural strength is relatively poor.
