Description
Technical Field
The utility model relates to a low temperature jar technical field especially relates to a novel composite bed for protecting boats and ships low temperature jar body.
Background
At present, the low-temperature tank body in shipping is generally a fuel tank above a deck. The outer side of the low-temperature tank body is provided with a heat-insulating layer for heat insulation, and the heat-insulating layer is usually made of polyurethane; because the low-temperature tank body above the deck of the ship body can be corroded by sunlight, sea wind and even seawater in the process of shipping, a protective layer is arranged on the outer side of the thermal insulation layer, and the material of the protective layer is usually GPR (general purpose glass reinforced plastics) which means glass reinforced thermosetting plastics or glass reinforced plastics. The existing GPR as a protective layer has the following defects:
(1) GPR has good corrosion resistance, and the hardness degree of the GPR can also effectively respond to external impact. However, since GPR is hard and has poor ductility, when the insulating layer is thick, stress deformation caused by cooling of the low-temperature can body at low temperature is transferred to GPR, which may cause local cracking of GPR.
(2) Due to the fact that the surface of the polyurethane heat-insulating layer is uneven, the surface of the GPR can also be uneven, and therefore the problem of poor attractiveness is solved.
(3) Because the polyurethane material of the heat-insulating layer is a material which is easy to corrode, the corrosion of the polyurethane heat-insulating material is easy to accelerate due to the fact that the GPR is directly attached to the surface of the heat-insulating layer, and the service life of the heat-insulating layer is shortened along with the increase of the navigation time.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention are combined to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention. Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. As used herein, the word "comprising" and similar words are intended to mean that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.
To the problem that prior art exists, the embodiment of the utility model provides a novel combined material for protecting boats and ships low temperature jar body.
Example 1
As shown in fig. 1, a novel composite material for protecting a low-temperature tank body of a ship comprises a polyurethane insulating layer 2; the polyurethane heat-insulating layer 2 is arranged on the outer side of the low-temperature tank body 1; an aluminum foil anticorrosive layer 4 is fixed on the outer side of the polyurethane heat-insulating layer 2 through a steel nail 3; at least one composite layer is arranged on the outer side of the aluminum foil anticorrosive layer 4; the composite layer consists of an inner glass fiber layer 6 and an outer unsaturated resin layer 5; the glass fiber layer 6, the unsaturated resin layer 5 and the aluminum foil anticorrosive layer 4 are formed by bonding; the outer side of the outermost composite layer is bonded with a glass fiber surface felt layer 7.
The outer side of the glass fiber surface felt layer 7 is also provided with a surface coating 8, and the surface coating 8 is a paint layer or other coating layer.
The material of the aluminum foil anticorrosive layer 4 is aluminum foil cloth, and the surface of the aluminum foil cloth needs to be smooth. The flatness of the aluminum foil anticorrosive layer 4 can effectively make up the defect of unevenness on the surface of the polyurethane heat-insulating layer 2. The aluminum foil anticorrosive layer 4 has excellent anticorrosive performance, can effectively protect the polyurethane heat-insulating material, and prevents the polyurethane heat-insulating material from being corroded.
