Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] The present invention provides mineral fibers (rock wool, glass wool), A
This relates to a mold-proof fiberboard that can prevent mold from forming due to dew condensation and a decrease in moisture control and absorbency by impregnating or applying a mold-proofing agent to a class or B-class insulation board (hereinafter simply referred to as a board). .

In general, mold grows significantly in environments with humidity and moderate temperatures, such as in insulation materials used between exterior wall materials and building frames, and in combination with modern insulation structures in base materials, such as plastics, wood, etc.
It has the disadvantage of causing discoloration, deterioration, or corrosion of fibers, etc.

In order to eliminate such drawbacks, the present invention adds one or more types of fungicides, especially metal powder containing copper ions, and fungicides to the surface of the board, between the fibers, and within the binder material to prevent performance deterioration. The present invention proposes a mold-resistant fiberboard that sufficiently maintains the desired properties and prevents corrosion of other components.

The anti-mold fiberboard according to the present invention will be explained in detail below. In the present invention, fiberboard refers to mineral fiberboard (rock wool, glass wool, gypsum whisker), metal fiber (Fe
, A/), organic fibers (Class A insulation board, Class B insulation sheathing board, wood wool cement), etc. Its size is approximately 9000 m (width) x 1800 m (length) x 5 to 20 cranes (thickness). In addition, as a fungicide, 2-(4-
thiazolyl)-benzimidazole (abbreviated as TBZ), phenylacetic acid, N-(fluorodichloromethylthio-)phthalimide (manufactured by Bayer AG, abbreviated as Prebentol A3), Prebentol A, which is an improved version of Prebentol A3, and 10-10-oxybisphenoxyalumine. (
Vinadine (abbreviated as Vinadine, manufactured by Pentron, Inc. in the United States) is a type of powder or liquid containing copper ions, and is made to exist in fiberboards by impregnating them (including felt), coating them, or adding them to adhesives. It is something.

The amount added is 0.05 to 1% based on the total weight.

Next, an example will be explained.

Two types of samples were prepared: a class A insulation board impregnated with 0.5% TBZ and a board in which the board was not impregnated with TBZ at all, and tested using mold resistance test method M-20. As a result, mold was not generated at all in the examples, and a lot of mold was observed in the comparative examples.

What has been described above is only one embodiment of the anti-mold fiberboard according to the present invention, and the anti-mold fiberboard with a coating film containing an anti-mold agent formed on the surface of the board or a sheet containing an anti-mold agent is pasted on the surface of the board. It also includes anti-mold fiberboard. Of course, it can also be impregnated with insect repellent such as termites.

As mentioned above, the anti-mold fiberboard according to the present invention has the characteristic that it can maintain the desired performance over a long period of time without corroding, reducing performance, discoloration, or deterioration as a base material.

Claims (1)

[Claims] (1) An anti-mold fiberboard characterized by impregnating and distributing one or more types of anti-mold agent, copper powder, etc. on a mineral fiber board, soft or hard fiber board.
