Deviation is also possible. That is, it is generally used as silicate magnesium.
Using sepiolite, the compounding ratio of this sepiolite is 5
When the content is reduced to 0 wt% or less, insufficient heat resistance is produced in the manufactured surface materials.
It became clear that it was tricky. Also, this time sepiolite
When the blending ratio of is more than 80 wt%,
It was found that the dispersibility of the material deteriorated, resulting in defective products.
Was. And the compounding ratio of sepiolite is 60-70 wt%
If the value is within the range, more favorable results can be obtained.
There was found. And the mixing ratio of glass fiber is 5 wt% or less.
In this case, the heat resistance of the manufactured face material may be insufficient.
It became clear. In addition, glass fiber should be 25 wt% or less.
In the case of above, the flexibility of the manufactured face
It became clear. And, the compounding ratio of the glass fiber is 1
A more preferable result is in the range of 0 to 20 wt%.
Was found to be obtained. Further, the mixing ratio of pulp is 10 wt% or less.
In the case of, the flexibility of the manufactured face material is insufficient
Became clear. Also, the mixing ratio of pulp is 30wt%
In the case of the above, the heat resistance of the manufactured face material is deteriorated.
It became clear. Then, the mixing ratio of pulp is 15
It is more preferable that the content is in the range of ~ 25 wt%.

When mixing, mix the binder into the slurry
Is also possible. This binder is about 2 ~ 10wt%
There are no particular restrictions. Mix the binder like this
In the case of sepiolite, glass fiber, pulp, oxidation
Antimony particles can be bonded to each other,
Softens, reduces the effects of humidity, and is non-flammable (not
Effect) and improve the formability of the face material
There is an effect that can be. The above-mentioned binder is blended in an amount of 11% or more.
The problem of smoke generation and the adverse effect on nonflammability
In addition, the content of 10% or less is preferable. Meanwhile, Vine
When the binder is less than 1%, the binder effect is small.
Problems, such as increased powder drop and reduced tensile strength.
You. Vinylidene chloride or vinyl chloride binder
A resin emulsion or the like can be used. Further, as described above, antimony oxide sol is used.
When mixed, the sol particles of this antimony oxide sol
Settles on organic matter such as pulp and covers it.
The degree can be reduced. Increasing the organic formula will
While the flexibility is improved, the combustion temperature rises,
The exothermic test specified in Article 1, item 5 of the Building Standards Law Enforcement Order
There was a problem that the condition was not passed, but the present invention
Antimony oxide sol is added in a prescribed ratio
This can solve the problem. The compounding ratio of this antimony oxide sol is
From 1 to 5 wt% is preferred from the range of quality. Organic mass
Less, even without adding antimony oxide sol,
Although incombustibility is obtained, there is a problem that lacks flexibility.
If the organic mass (30 wt% or more) is too large,
5% or more antimony oxide sol with too much organic mass
However, there is a problem that incombustibility cannot be obtained even when adding. Each of the above-mentioned components is arranged in a predetermined range.
The weight of the combined slurry is adjusted using a wet paper machine.
50-300 g / m^TwoIf you make paper so that
Heat resistant despite pulp (organic content)
Excellent in heat resistance and flame resistance, but mechanical strength
It turned out to be flexible and flexible. Especially the grammage
Range from 100 to 200 g / m^TwoIf you do, lightweight
In addition, it has mechanical strength and flexibility as a face material
This face material is foamed with foam such as a phenolic resin foam layer.
Continuous lamination or
It has been found that post-pasting is easy. The present inventors have constructed the non-combustible soft facing material described above.
Various investigations were conducted on the range of components to be formed.
As a result, 60-70 wt% of silicate magnesium
Is a more preferable range.
A more preferable range is 0 to 20% by weight.
Is more preferably in the range of 15 to 25 wt%.
It was confirmed. [0032] [Comparative Example] Using exactly the same method as in the above embodiment,
