Abstract

PURPOSE:To provide the titled composite board which is light and has high- strength and high heat-insulating performance, by a method wherein, after peripheries of two particular metal sheets, positioned facing and opposite to each other, are airtightly blocked, a resin composition is injected, foamed, and cured between the metal sheets, and simultaneously, the sheets are deformed by dint of a foaming pressure. CONSTITUTION:After two flexible metal sheets 2, such as stainless steel sheets, being impermeable to, for example, an uncured resin composition or a resin melt are positioned facing and opposite to each other and mounted to a fixed frame 1, the peripheries of said metal sheets 2 are positioned between the air-tight nip formed by tension leaves 3, 3 to secure them to the fixed frame 1. A foaming resin composition, i.e., urethane series, is then injected between the metal sheets 2, 2 whose peripheries are airtightly blocked, to foam and cure the composition. Simultaneously, the metal sheets 2, 2 are stretch-deformed or plastic-deformed by dint of a foaming pressure to obtain a desired composite board A in which the metal sheets 2, 2 and a foamed resin 4 are united into a monolithical unity. USE:The boards are aligned on a roof body consisting of trusses 6 to construct a roof of a long span frame work.

Description

[Detailed description of the invention] This invention relates to a method of manufacturing a foamed resin composite board.

The purpose is to provide a manufacturing method for a composite board that has Ij1 and roars under axle load, #Ii#thermal properties, and is suitable for Jil roots of Dajiang Passenger Structures, etc.

The cost of this invention is substantially uncured II! Fat composition Rurui *11 bath melting is not masochistic. , and has aJtlA properties, are arranged opposite to each other, and air is emitted between the peripheral edges of these two O-boards, and the peripheral edges are fixed to a certain frame, and the two thin plates are Inject a foamable resin composition in between, and
Foaming @N characterized in that it is foamed and at the same time the thin plate is deformed or horizontally deformed by -1 pressure.
This is a method of procuring composite boards.

According to this procurement method, the periphery is closed to the trachea, fixed in a certain frame, and placed 9 sheets facing each other, between which the foaming pressure of 9 foaming compositions is injected, respectively. It is compressed in one direction outward and tension is applied, or it is deformed by the tension and deforms into a sphere II shape. Therefore, the composite plate made by foaming and solidifying the foamed resin composition has a shell structure in which the internal pressure is balanced with the tension in the thin layers on both sides, giving it a high rigidity of 9111 degrees. I can do that. Yen - 〇孭/
111111, for example, if the hard polyurethane tatami O has relatively high pressure m* degree and attachment stability, even if #i constant frame is removed, the female plate tension and internal pressure will be balanced and the shape 1 dimension will be stable,
As a single composite board, it weighs 11L! .

@1111i shows one example of this manufacturing method. This manufacturing method is as follows: - Two square stainless steel thin plates 2 are arranged facing each other on a short frame L, and the two overlapping 9 peripheral edges are airtight between a pair of upper and lower presser plates 3, 3! 1% and fix the fixing frame IK via the presser plate 3t. Isocyanate, polyol, and blowing agent are placed on the thin plates 2 and 2 fixed in this way.

Inject a tactile texture composition consisting of a stabilizer and the like. The two thin plates 2.2 have peripheral edges [! Because it is, it is threatening - fat composition - 〇! I limestone, two thin plates 2.2
It acts as a tension force that expands the spherical shell, causing elastic deformation or uniform deformation into a spherical shell shape. Inner IIO is almost turned into 1 Urethane Yoiro 4 is 2 fall O sphere fa-shaped thin plate 2.2 Kyc, and as it is laid down, thin plate 2 @ 2Km is attached at the interface, thin plate 2
．． 2 and the foamed urethane*li4 are combined to form a plywood plywood board.

This O composite board A#i foamed urethane 111r4 has high pressure strength and is firmly attached to the thin plate 2.2, so 280
1g board 2, 20jillslS41tN, tRJI2
Kakaku Nodo <Writing Department! If you want to keep it in S group, #Aj
i! Even if it is removed from the frame 1, the shape and dimensions do not change, making it possible to use it as a single composite board.

For example, as shown in Fig. J115, a rectangular fixed frame l is made using C-shaped steel, both 11iK thin plates 2.2 are fixed, a space for the trachea is formed between the thin plates 2, 2, and the frame is placed in this space. By injecting the commercially available resin composition, it is possible to form a composite board consisting of the peripheral fixed frame 1, the thin plate 2°2, and the foamed resin 4 without removing the fixed frame 1'.

In the diagram, a foamed I11 resin composite board is formed along the upper surface of the truss 6, forming a large-scale structure. To construct this roof, thin plates 212 made of #i steel in a square or regular hexagonal shape are stacked and fixed to the trachea between the peripheries with force, and stretched over the truss 6.
11ilj that matches the size! The frame IK is fixed at its periphery and is made up of trusses 6 and laid out on a nine-roof knitted body. Next, a foamable resin composition is injected between each of the thin plates 2 and 2, and the foam is solidified, and at the same time, tension is applied to the two thin plates using the resulting pressure, and the two thin plates are deformed into a spherical shell shape. Mutonashiho machine is constructed.

In order to build this Otori machine, I made two thin steel plates in advance.
, 2 are airtightly fixed between the peripheral parts tS* of the (support) foot frame 1
It was fixed on the truss 6, and the composition was placed on the truss 6, and the composition was large and collapsed and deformed into a spherical shell shape. You may. The placement may be defined by continuous support or by point support.

The composite plate manufactured by this manufacturing method is not limited to the shape 04 described above. For example, in the 6th H, Todoroki p to form a composite plate, and the composite plate center 1! Attach 7 pieces of diaphragm plate to connect the two thin plates 2 and 2, and the thin plate 2.20 mm.
t can also be limited and deformed. It is also possible to use two thin plates with different elastic moduli or proportional elastic moduli to make the deformation of the front and back sides asymmetrical.

The substantially uncured resin composition or flexible thin plate that is impermeable to the 11tr# fusion used in this IA@ includes steel plates, stainless steel plates, synthetic resin plates, rubber plates or sheets thereof, and films on the opposite sides. Thin film! Yes, part 5~5
A thickness of 0 Jlmm is commonly used. Also, group lIk
It is also possible to use a fabric that is dense and substantially impermeable to the uncured 1111r composition or mineral resin bath melt.

Urethane type, area type, and phenol superimposed types are available as l111 mm materials.

j11 pressure #i is selected depending on the elastic modulus of the thin plate used, the proportional member elastic modulus, or the desired degree of deformation.

Using a blowing agent such as Kri or 7 Leon, which controls the blowing pressure, heat the mixture at a injection rate of 1.5 mm. The urethane-based composition is easy to handle, allows relatively high crushing pressure, and can form a hard foamed 111111r with good adhesion to thin plates, so it is suitable for the purpose of ζCj4BH.

This example has the above-mentioned structure, and the AM composite board obtained by this manufacturing method is deformed by the force applied in the direction in which the opposing thin sheets are pushed and spread, and is injected into the inside, causing the next generation. Pond resin,
Internal pressure and balance shell structure t-consist. Therefore, even if the thin plate has low rigidity, the composite plate has high rigidity.
That's why.

Also, Thin Board and Yaobu I! Since it is made of fat, it has a gutter volume of 6p and has excellent insulation performance. For this reason, the Taipei Kanpo structure oi
It is suitable as a panel for TA machines, etc., and the composite board can be formed by attaching it to the frame at the construction site, so efficiency can be achieved in terms of construction as well.
