性積層体に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fire-resistant laminate, and particularly to a fire-resistant laminate used for, for example, drainage pipes, ventilation pipes, wall materials, etc. that require fire resistance.

The so-called Asano fireproof pipe (trade name: Kanto Asano Pipe Co., Ltd.), which has a cladding, is known.

しかも経済性が悪いという問題点があった。[Problem to be solved by the invention If] In the conventional fire-resistant laminate, it is not possible to bond a hard vinyl chloride pipe and an asbestos cement pipe or a fiber-reinforced mortar-coated pipe (hereinafter referred to as "inorganic refractory layer"). However, it was not possible to integrate the two. For this reason, the inorganic refractory layer itself must withstand bending due to its own weight, external impact, etc., and must be formed to have a thickness greater than that necessary to impart fire resistance. Therefore, the weight is heavy;
Moreover, there was a problem that it was not economical.

ができなかった。In addition, the inorganic refractory layer has been formed by curing in a mold in a batch method, but this has the problem of a complicated manufacturing process and poor productivity. In particular, when asbestos cement is cured, high temperatures and pressures are required, and the inner hard vinyl chloride pipe becomes soft and deformed, making it impossible to integrally mold it.

The synthetic resin layer and the metal layer are bonded together with an adhesive, and the metal layer and the inorganic refractory layer are bonded together with an inorganic binder.

As a result, the synthetic resin layer and the inorganic refractory layer are integrated.

Therefore, since the inorganic refractory layer can be made thinner than in the past, the overall weight can be reduced and economical efficiency can be improved.

接着可能な無機耐火物層１８が形成される。The resin layer 12 may be a pipe or a flat plate. A metal layer 16 is adhered onto the outer surface of the resin layer 12 using a rubber adhesive 14, such as a chloroprene adhesive, which can bond resin and metal. The metal layer 16 is made of a metal foil such as aluminum foil, for example, and when the resin Jii 12 is a pipe, it is formed by winding it in a spiral shape. The thickness of the metal layer 16 is approximately 5 to 200 μm. Then, on the outer surface of this metal layer 16, an inorganic refractory layer 18 that can be bonded thereto is formed.

The metal layer 16 is bonded to the resin layer 12 via the adhesive 14. That is, by interposing the metal layer 16,
The inorganic refractory layer 18 and the resin layer 12, which cannot be directly bonded, are integrated. Therefore, since the inorganic refractory layer 18 is reinforced by the resin layer 2, it can be made thinner than before.
