JPH10338767A - Incombustible, heat insulating, soundproof and flexible board and production of flexible board - Google Patents

Abstract

PROBLEM TO BE SOLVED: To produce a lightweight flexible board having incombustibility, heat insulating and soundproof properties and further flexibility by utilizing characteristics of a flexible expandable urethane and an inorganic emulsion. SOLUTION: This lightweight flexible board is produced by conveying a flexible expanded urethane foam 1 with a conveyor 2, pressurizing the urethane foam 1 with a pressurizing roller 3, providing the flexible expanded urethane foam 1 with a flat state, further continuously filling an inorganic emulsion 5 from an upper nozzle 4, squeezing out a part of the inorganic emulsion contained in cells with a pressurizing roller 6, conveying the resultant foam 1 with conveyors 7 and 8, forcibly heating the foam 1 with a dryer 9, etc., and making particles discontinuous with ultrasonic waves 10 at about a time when the foam is nearly cured, providing flexible boards 11, then stacking a prescribed number of the flexible boards 11 up to a pile with a lifer, drying the resultant pile of the flexible boards 11 in an aging chamber where the temperature, humidity and ventilation are kept in the optimum conditions and then providing the final product. The flexible expanded urethane material can be molded and applied to boards, blocks, imitation stones, imitation wood, decorations and storerooms.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the use of a soft urethane foam and an inorganic emulsion to make use of the properties of both, thereby providing non-combustibility, heat insulation, soundproofing, light weight and flexibility.
The present invention relates to a method for manufacturing a flexible board which can be used freely on a curved surface or a special part of a building and which can simultaneously perform non-combustion, heat insulation and soundproofing work in a single process.

[0002]

2. Description of the Related Art Conventionally, plate materials which are non-combustible and are used for curved surfaces of buildings are custom-made or expensive, and there is no plate material having heat insulation and soundproofing.

[0003]

This has the following disadvantages. I. There is no board material that is nonflammable, lightweight, flexible and can be used freely on curved surfaces and special parts of buildings. B. It is non-flammable, so heat insulation and soundproofing work cannot be performed simultaneously in one process. C. Heat insulation and soundproofing work requires specialized engineers. D. Employing heat insulation and soundproofing construction increases labor, construction period and cost. E. There is no plate material available for both interior and exterior. F. There is no building material made of flexible urethane foam. The present invention has been made to solve the above drawbacks.

[0004]

Means for Solving the Problems A flexible plate material that is nonflammable, heat-insulated, soundproof, and made inorganic by making use of the characteristics of a flexible urethane foam.

[0005]

Embodiments of the present invention will be described below. I. In FIG. 1, a soft urethane foam (1) is conveyed on a conveyor (2), conveyed and pressed through a pressure roller (3), and the soft urethane foam (1) passed through the pressure roller (3) is flat. Restore state. B. The soft urethane foam (1) which has passed through the above (1) is filled with the inorganic emulsion (5) continuously from the upper nozzle (4) with the restoring force. C. A part of the inorganic emulsion (5) contained in the bubbles is relatively squeezed out by the pressure roller (6) and conveyed by the conveyor (7). D. After passing through the above-mentioned (c), it is passed through a conveyor (8) and forcibly heated by a drier or the like (9), and when almost cured, the particles are discontinued by ultrasonic waves (10) (the urethane particles are covered with an inorganic emulsion. ). E. The flexible board (11) made of the above d.
A predetermined number of sheets are piled up by a lifter to make a single pile, transferred to a curing room in which the temperature, humidity and ventilation are controlled in an optimal state, and the excess water is removed and dried to obtain FIG. 2 of the final product. By molding a soft urethane foam material, it can be applied to blocks, artificial stones, artificial trees, decorative articles, and ornaments in addition to boards and the like.

[0006]

According to the characteristics of the inorganic material and the urethane material, the material is lightweight, non-flammable, easy to cut, and flexible, so that it can be used freely on curved surfaces or special parts of buildings. In addition to the need for specialized technicians in each process, heat insulation, soundproofing, and dew condensation prevention work can be performed at the same time, and by using composite boards, labor, construction time, and costs can be significantly reduced, A great cost reduction effect is brought about.
