Field of the Invention The present invention relates to a heat insulating material used for forming a heat insulating layer for pipes, tanks and equipment, and more particularly, it is resistant to corrosion when it is used for heat insulating of a heat insulating body made of metal. The present invention relates to a heat insulating material having an anticorrosion function that effectively prevents and suppresses corrosion.

That is, when there is a gap at the interface between the heat insulating material and the object to be heat-insulated and the two parts are partially in contact with each other, if rainwater or the like intrudes into it, a wet corrosive environment containing salt that has entered with the rainwater or the like is extremely high. It is easily formed and corrosion is further accelerated. For example, if the object to be adiabatic is made of carbon steel etc., rainwater etc. will accumulate in the gaps at the interface with the heat insulating material,
Partial corrosion and general corrosion occur.

により均一な防食性能が得られないなどの欠点がある。In order to prevent and suppress such corrosion,
Conventionally, a method of applying an anticorrosive paint on the surface of a heat-insulated body and disposing a heat insulating material on the outer side thereof has been applied. As this anticorrosive paint, for example, Japanese Patent Application Laid-Open No. 4-270768 discloses a zinc rich paint containing a scale-like zinc powder and an organic or inorganic resin as main components. However, such a method of coating the entire surface of the heat-insulated body has drawbacks that not only is time-consuming for construction, but also uniform corrosion resistance cannot be obtained due to uneven coating.

一体に密着積層した断熱材を提案している。There is also known a heat insulating material in which the above-mentioned anticorrosive paint is applied to the inner peripheral surface of a molded heat insulating material formed by molding a foam or the like into a desired shape and facing the heat insulating material. According to this, because the anticorrosion paint is applied to the heat insulating material in advance,
It is possible to omit the work of applying the heat-insulated body, and it is possible to significantly improve the workability. The applicant of the present invention has also previously disclosed, in Japanese Utility Model Publication No. 2-35118, an anticorrosion suppressing material in which an anticorrosion suppressing material is carried on a reinforcing material having water permeability on the inner peripheral surface of the molded heat insulating material facing the body to be insulated. We have proposed a heat insulating material in which elution strengthening materials are closely adhered and laminated.

観点から特に改善が望まれている。However, the anticorrosion layer formed on the inner peripheral surface of the conventional anticorrosion paint or heat insulating material contains an inorganic substance such as nitrite, phosphate or chromate as a main component. However, it is not preferable in consideration of the effects on the environment. Specifically, nitrites are at risk of producing nitrosamines, phosphates cause eutrophication of rivers and lakes, and chromates are toxic, making these substances toxic during long-term use. It leaks out with the moisture that invades from the outside and contaminates the soil and water system. This is particularly desired to be improved from the viewpoint of environmental protection in recent years.

間に滞留して被断熱体の腐食をより進行させてしまう。Further, the molded heat insulating material is generally molded with an inner dimension larger than the outer dimension of the heat insulating material, and as a result, when the molded heat insulating material is fitted on the heat insulating material, the heat insulating material is interposed between the heat insulating material and the heat insulating material. Not only does a gap occur to reduce the heat insulating effect, but moisture that has entered this gap is difficult to be removed to the outside, and stays in the gap to further promote the corrosion of the heat-insulated body.

The following flexible urethane foams are preferable, and the number of cells is 40
The number is preferably not less than 40 pieces / inch, particularly 40 to 80 pieces / inch. If the residual compressive strain is large, good adhesion between the body to be insulated and the anticorrosion layer described later cannot be obtained. The number of cells is preferably as high as possible in terms of water absorption, and if the number of cells is small and the number of cells is rough, the coating property of the anticorrosive material is deteriorated. The thickness of the cushion material varies depending on the relative dimensional difference between the cushion material and the heat insulating material, but is preferably about 3 to 7 mm. If it is too thin, the adhesion to the heat-insulated body will decrease and the water absorption will be small,
On the other hand, if it is too thick, the workability on the heat-insulated body will deteriorate.

The organic rust preventive agent that forms an anticorrosive layer together with the scale-like zinc powder is a compound that does not contain a nitrogen compound and a phosphorus compound, for example, a hydroxylaryl fatty acid and an alkali disclosed in JP-A-63-310981. Examples thereof include those obtained by adding soap made of metal to an aqueous metalworking oil, and those containing an alkali metal salt of p-methylcinnamic acid as an active ingredient disclosed in JP-B-59-21952. .

Here, the amount of the scale-like zinc powder blended in the sacrificial anticorrosive material is preferably as high as possible from the viewpoint of anticorrosion performance, but if the blending amount exceeds 50% by weight, uniform dispersion becomes difficult. For this reason, it is preferable that the content of the scale-like zinc powder in the anticorrosive material is 30 to 50% by weight. As the binder, a water-soluble binder is preferable,
Although starch syrup, polyvinyl alcohol, starch and the like can be mentioned, starch syrup having an adhesive property at room temperature is particularly preferable in consideration of the adhesiveness to the heat insulating material.

Further, since the cushion material is made of a water-absorbing material, even if rainwater or the like enters the interface between the heat insulating material and the heat insulating material, the rainwater is absorbed by the cushion material without staying at the interface. Since zinc, which is the main component of the anticorrosion layer, has a greater ionization tendency than iron, it acts as a sacrificial metal on a heat-insulated body made of a steel material such as carbon steel and prevents corrosion of the heat-insulated body. In addition, the corrosion inhibiting effect is further enhanced by adding a rust preventive agent. Moreover, since this rust preventive is a compound containing no nitrogen compound and no phosphorus compound, the problem of environmental pollution can be solved. Further, by providing the cushioning material and the anticorrosion layer not only on the inner peripheral surface of the molded heat insulating material facing the object to be insulated, but also on the joint surface with another molded heat insulating material, the anticorrosion function becomes more reliable.
