(Field of Industrial Application) The present invention relates to a noncombustible shingle (flat roofing material) with excellent waterproofness and toughness, which is mainly used for construction on the sloped roof surface of a building. (Prior art) In recent years, flat roofing materials (trade name: Colonial Color Vest, etc.) made of asbestos cement boards with a thickness of 3 to 5 mm and felt-like roofing materials have been used to construct lightweight roofs or roofs with new designs. Asphalt shingles (flat roofing materials), which have a core material impregnated with asphalt and colored sand sprinkled on the surface, have come to be widely used. However, flat roofing materials made of asbestos-cement boards have the disadvantage that they tend to break when someone climbs onto the roof, which causes many problems. On the other hand, asphalt shingles are flexible and do not break, but they are easily flammable in the event of a fire, which is a fatal drawback in terms of fire protection. Therefore, instead of asphalt, a small amount of synthetic polymer binder such as synthetic resin and synthetic rubber is used, and inorganic or organic nonwoven fabric, woven fabric, etc. is impregnated with a slurry mixed with mineral powder, inorganic fiber, flame retardant, etc., and colored sand is used. A flexible, non-combustible shingle having the surface covered with the material has been proposed, and one that passes the standards for non-combustible materials stipulated in Ministry of Construction Notification No. 1828 has been obtained. The applicant of the present patent application also
No. 55-012070, method for manufacturing non-flammable coated paper (1972)
A non-combustible shingle was obtained by applying the invention of ``Public Announcement Decided on November 30, 2015'', but it was satisfactory in that it was non-combustible, strong and difficult to break, durable and lightweight. Since the coating is made by binding a large amount of mineral particles and fibers with a small amount of polymer binder, it is impregnable and permeable to rainwater, and has the disadvantage of leaking when the wind and rain pressure is large. . (Increasing the amount of organic polymer binder eliminates rainwater permeation, but it fails the test for non-combustible materials.) (Problems to be solved by this invention) Therefore, the present invention is designed to have no water permeability at all, and to be flexible. The objective is to obtain a durable, noncombustible shingle (flat roofing material) that is strong enough to not break even when stepped on by a person. (Means for solving the problem) As a means for that purpose, the core material sheet used in the invention of Japanese Patent Application No. 58-13571 (Asphalt Roofing) previously filed by the applicant of the present application, that is, the "polyethylene synthetic pulp" Paper made from 40 to 60% by weight of vegetable fibers and glass fibers is processed by heat and pressure, and polyethylene synthetic pulp is melted and rolled to create an impermeable layer in which the fibers are bound and integrated. By applying the "core material sheet forming the core material sheet" to the noncombustible shingle of the present invention, we aim to develop a completely water-impermeable and flexible roofing material. That is, the present invention uses a sheet made by heat-pressing 40 to 60% by weight of synthetic resin pulp, glass fiber and vegetable fiber as the main raw materials, and 10 parts by weight of inorganic fibers in water. defibrated, dispersed,
A slurry-like mixture of 5 to 20 parts by weight of synthetic resin or synthetic rubber in the form of an emulsion or solution and 50 parts by weight or more of a flame retardant filler such as aluminum hydroxide, ettringite, dolomite, etc. The core material sheet is impregnated and coated, mineral powder is sprinkled on the outer surface, and dried and solidified.
It is a non-combustible shingle that is cut into appropriate shapes and dimensions. Further, the core material sheet is a non-combustible single material in which synthetic resin pulp is melted and rolled in the heat-pressing process, and each material is uniformly bonded and integrated to form a water-impermeable layer. In addition, a flame retardant is added to the slurry mixture to improve its nonflammability, and it also contains a thickener and various powder fillers to reduce workability, weather resistance, and cost. It is a non-combustible shingle with various colored paints applied to the mineral particles sprinkled on the back side. In the present invention, synthetic resin pulp refers to, for example, products SWP-E, SWP-UL (manufactured by Mitsui Petrochemical KK,
Fybrel (manufactured in the United States) is a pulp-like, multi-branched, low-melting-point polyethylene or synthetic resin fiber such as polyester. Average fiber length 0.6-1.6mm, specific gravity 0.95, well dispersed in water, suitable for mixed papermaking with glass fiber and wood pulp. Melting point is 90-140
When a material of 0.degree.
The synthetic resin pulp needs to be used in an amount of 40 to 60% by weight in order to bind and integrate with other fibers to form an impermeable layer. If it is less than 40% by weight, it will not be possible to form a sufficient water-impermeable layer, and if it is more than 60% by weight, the nonflammability will deteriorate, so it is necessary to select from the above range. Glass fiber improves the toughness and nonflammability of the core sheet, so it should be added at 30 to 50% by weight.
The blending amount is optimal. The vegetable fibers include wood pulp, waste paper, rag fibers, etc., and improve the flexibility and tear strength of the sheet. In addition, heat-pressure processing means that the melting point of synthetic resin pulp is 90
Using a material with a temperature of ~140℃, the synthetic resin pulp melts when it is wound through a roll, cylinder, or dryer heated above its melting point, pressurized, and rolled.
It can be rolled and bonded and integrated with glass fibers and vegetable fibers to form an impermeable layer. When making the core sheet using a paper making machine, P.
VA fibrous binders, other water-soluble polymeric binders, and conventional papermaking pastes may also be used. The core material sheet constructed in this way has excellent water impermeability and flexibility, so by impregnating and coating it with the non-combustible mixture described later, it is possible to create a completely water-impermeable, tough, non-combustible single base material. I can do it. Next, to explain the slurry mixture used in the present invention, inorganic fibers such as glass fiber and asbestos
Stir 10 parts by weight in water to defibrate and disperse.
Synthetic resins include water-soluble melamine, polyvinyl alcohol resin, emulsion type acrylic, ethylene vinyl acetate resin, etc. Synthetic rubbers include styrene-butadiene rubber, polybutadiene rubber, styrene-isoprene rubber, isoprene rubber,
Emulsions such as acrylonitrile butadiene rubber, chloroprene rubber, butyl rubber can be suitably used. A combination of one or more synthetic resins and/or synthetic rubbers, such as
20 parts by weight, most preferably 8-15 parts by weight, are formulated as an emulsion or aqueous solution. If the amount is less than 5 parts by weight, the binding force as a binder will be insufficient and a strong coating layer will not be obtained, and if it is added more than 20 parts by weight, the nonflammability will decrease and the material will not pass the standards as a noncombustible material. Flame-retardant fillers include compounds such as aluminum hydroxide, ettringite (calcium sulfoaluminate), and dolomite (a mixture of magnesium carbonate and calcium carbonate), which contain a large amount of condensed water and exhibit endothermic and flame-retardant effects at high temperatures. Contains 50 parts by weight or more. If the amount is less than 50 parts by weight, the nonflammability will be poor. The coating layer obtained by mixing 10 parts by weight of inorganic fibers with 5 to 20 parts by weight of synthetic resin, synthetic rubber, and 50 parts by weight or more, preferably 50 to 100 parts by weight of flame retardant filler, is as follows:
It is non-combustible and has strong binding properties, and it firmly fixes mineral grains scattered on the surface, making it a durable roofing material. It is also desirable to add a conventional flame retardant to further improve and ensure nonflammability. In addition, in order to achieve an appropriate viscosity with good coating and workability, sodium polyacrylate, polyvinyl alcohol,
It is recommended to add methylcellulose, carboxylmethylcellulose, starch, etc. Further, in order to improve weather resistance and increase the amount, mineral powder particles such as talc, charcoal, and quartzite can be added. (Example) Next, an example of a method for manufacturing the noncombustible shingle of the present invention will be described.
