Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flame resistant composition having excellent flame resistance and flame retardancy and excellent adhesiveness.

[0002]

2. Description of the Related Art Recently, products are often required to have flame resistance and flame retardancy, and adhesive composition products are often desired to have flame resistance and flame retardancy. Many products are commercially available as the adhesive composition, and proposals for many new products have been made.However, since many of these products are mainly composed of organic compounds, they are flame-resistant, The flame retardance was not sufficient.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to meet the above demands and to solve the conventional problems in order to satisfy the above demands. That is, it is an object of the present invention to provide a flame resistant composition having excellent flame resistance and flame retardancy, particularly sufficient flame resistance, and excellent adhesiveness.

[0004]

The present invention has been completed as a result of intensive studies by the present inventor in order to achieve the above object. That is, the flame-resistant composition of the present invention comprises a viscous material obtained by dissolving sorbit and borax in water and inorganic hydroxide.

As the inorganic hydroxide used in the present invention, aluminum hydroxide, calcium hydroxide, calcined gypsum and the like are preferable. Moreover, you may use these 2 or more types as an inorganic hydroxide. It should be noted that the higher the amount of the inorganic hydroxide compounded is, the better the flame resistance and flame retardancy are, but 1% of the above viscous material
If the amount is more than 20% by weight, the resulting composition becomes brittle, which is not preferable. Moreover, when adding and blending an inorganic hydroxide to a viscous substance, you may add an inorganic hydroxide, after adding the solvent which can be mixed with a viscous substance, such as methyl alcohol, to a viscous substance. In order to dissolve sorbit and borax in water, it is preferable to heat these mixtures to a temperature of 80 to 90 ° C.

[0006]

The viscous material used in the composition of the present invention, that is, the viscous material obtained by dissolving sorbit and borax in water is also flame-resistant and flame-retardant, and is paper, wood, concrete surface, polyethylene film, etc. Although it has adhesiveness to, in the composition of the present invention, by further adding an inorganic hydroxide to this viscous substance, due to the interaction of each component in the composition, it is particularly excellent. Further, the composition of the present invention has flame resistance and flame retardancy and is excellent in adhesiveness.

The composition of the present invention is composed of components of low molecular weight compounds and does not cure at room temperature. However, the composition of the present invention hardens due to high heat, and becomes entirely stone-like. The uncured composition can be uniformly filled into the box by pouring it into, for example, a box-shaped one, and applying vibration to the box-shaped composition. It can be formed into a shape.

In the composition of the present invention, the composition containing sorbit, borax and aluminum hydroxide becomes a stone-like noncombustible substance when burnt with a flame. When it is left at room temperature, it becomes a softened solid, but when it is baked again with a flame, it hardens again and becomes a stone. However, a composition obtained by adding calcium hydroxide or calcined gypsum to the composition containing the above three components hardens in the same manner as above when burned with a flame to become a stone body, which is left at room temperature. However, it does not soften. By appropriately utilizing such an action, it is possible to freely take an aspect according to its application field.

【Example】

 Example 1

110 g of borax, 110 g of sorbit and 150 g of water were mixed, and this mixture was heated to 80 ° C. to dissolve the borax and sorbit in water to obtain a transparent viscous substance. This viscous material adhered to wood, paper and polyethylene film at room temperature, and when it was applied to paper, it gave flame-resistant and flame-retardant viscous paper. The hard pasty composition of the present invention obtained by adding 400 g of aluminum hydroxide powder to this viscous material has excellent adhesiveness and also has sufficient flame resistance and flame retardancy. Atsuta When the composition was burnt with a gas flame, it became a non-combustible stone. Further, although this stone body was softened when left at room temperature, it was hardened again when it was fired again, and turned into a stone body. Example 2

120 g of borax, 120 g of sorbit and 200 g of water were mixed, and this mixture was heated to 80 ° C. to dissolve the borax and sorbit in water to obtain a transparent viscous substance with high viscosity. The composition of the present invention obtained by adding 450 g of aluminum hydroxide powder to this viscous material had excellent adhesiveness and had sufficient flame resistance and flame retardancy. When this composition was applied to the surface of an aluminum plate and heated from the back surface of the plate, the composition adhered well to the aluminum plate. Example 3

20 to 20 with respect to the viscous material obtained in Example 2.
50 wt% calcined gypsum was added and mixed, and this mixture was kneaded to obtain a flame resistant composition of the present invention. This composition was excellent in flame resistance, flame retardancy, and adhesiveness, and when the composition was adhered to wood and burned, the wood did not burn to the composition of the present invention even if it burned. Example 4

To 100 parts by weight of the viscous material obtained in Example 2, 110 parts by weight of slaked lime (calcium hydroxide) was added and mixed to obtain a white creamy flame-resistant composition of the present invention. This composition was excellent in flame resistance, flame retardancy and adhesiveness, and adhered well to wood. Further, this flame resistant composition did not dissolve immediately even if water was applied to its surface, that is, it had poor water solubility. Example 5

To the viscous material obtained in Example 1, 200 g of aluminum hydroxide was added, and further 200 g of slaked lime (calcium hydroxide) was added to the composition of the present invention excellent in flame resistance, flame retardancy and adhesiveness. I got a thing. When this composition was burnt with a gas flame, it became a stone-like incombustible body which did not soften even when left at room temperature. Example 6

Flame resistance, flame retardance, flame resistance, and flame resistance were the same as in Example 5 except that 200 g of calcined gypsum was used instead of 200 g of slaked lime.
A composition of the present invention having excellent adhesiveness was obtained. When this composition was burnt with a gas flame, it became a stone-like incombustible body which did not soften even when left at room temperature.
