Description

[Detailed description of the invention] seat of The present invention relates to a method for producing a laminate, particularly a seat cushion or a seat back support. For laminates used as Concerning vandal resistant or damage resistant seats.

Some vandal resistant seats offered for use in modern public transport are , they have been criticized for being too stiff and lacking in comfort. For example, Austra The seat described in Ria Patent Application No. 52495/86 is made of polyurethane. Rethane (V6O13) and Moca have been used. Uniroya l　Au5t, supplied by Pty, Ltd., which has a wire diameter of 0.75 mm. A high tensile strength elastomer with a Shore A hardness of approximately 75-85 used with wire mesh. provide the market. The wire in this structure is moderately stiff molded without elastomer show the product. Adding elastomers creates a very stiff, board-like seat. workman The lastomer is rigid when formed into a seat without wire reinforcement. on the other hand, The chain mail-shaped mesh is made of softer and more flexible elastomer. It does little to improve flexibility unless it is. Furthermore, this place The process uses materials that need to be kept at high temperatures (i.e. above 100°C). and requires a long curing period (e.g. 2 hours) and an additional 8 hours of post-curing. do. Vickers Xatal AU-B-12028/88 is vandal resistant An attempt to mold the material into the shape of the seat while retaining the flexibility necessary for some degree of comfort. A description of a rigid molded seat pan covered with a flat sheet illustrates the difficulty. It is listed. Seat shape molding methods have been left behind in favor of hard seat pans. It seems that it has arrived.

British Patent No. GB 204,107,420 (J, L.

Danton and M. Duret also teach wire reinforcement structures. this produces softer, more flexible seats, but this method only produces flat seats. There are other manufacturing limitations that do not appear to be possible. J.L., Danton and M. .

Duret describes the plain view in FIGS. Describes how three-dimensional seat shapes can be manufactured as opposed to flat seats are doing. This involves attaching a prefabricated sheet to a rigid plastic or metal frame. This is done by molding or attaching it into the system.

Unfortunately, a flat sheet attached in this manner allows it to stretch and bend. (which this material cannot, of course) tend to be stiffer. Ru. The result is a fairly hard and uncomfortable seating material.

Other published methods for manufacturing vandal-resistant or damage-resistant seats, e.g. National Patent No. 3,647,608 No. 3,647,608 No. 3,647,608 describes a softer seat. It describes the method of manufacturing. However, produced by this method The seat offers little resistance to damage from being banked; and that the product is within the density range normally used for seating, i.e. per cubic meter. It is made of 35 to 60 kg of foam, and is not connected at random. Reinforced with oriented wire or metal fibers, making it easy to cut. I found out that it can be done. This type of foam has relatively low tensile strength and When used in combination with unconnected wire rods, it is difficult to chop or pull them. Seats manufactured in this way have limited resistance to attack by vandalism. It merely shows the resistance that has been applied. In this invention, S, Enlow is large. damage that can be caused by fire from either large or small ignition sources. However, I did not consider it. Therefore, the overall resistance of the product manufactured by this method Gender is limited.

The current advantageous method of producing vandal-resistant seats is to provide a seat that is mounted on a board and is flame retardant. Made of wire-reinforced microporous urethane elastomer seat molding supported on a foam Includes structure. The seat molding can then be removed or damaged. The seat must be covered with woolen fabric as it is only difficult to attach it to the seat. No. The fabric is treated with three thick adhesive layers. is also treated with adhesive and the adhesive is allowed to dry. Next, the seat molded product and the adhesive-coated wool fabric are placed in an infrared oven and heated until tacky. to reactivate the adhesive. Then take care to line up the pattern and remove wrinkles. While placing the woolen fabric on the seat. Do not pull the woolen fabric near the corners or sides of the seat molding. Prepare the molding by tensioning and stabilizing it on a board. seat molding Placing the treated wool on the product and arranging the parts is very time consuming. Moreover, advanced technology is required. As can be recognized, failure during this process is It always results in expensive scrap.

Accordingly, the prior art techniques specific to manufacturing vandal resistant seats have several limitations.

The aim of the invention is to alleviate at least some of the above-mentioned disadvantages.

Chlorinated paraffins can be either liquid or solid, e.g. For example, CERECLOR 70 or 70L (CERECLOR is I, C, 1, (registered trademark of ) may be used, but liquid chlorinated paraffin is preferred. stomach.

The formulation of the foam polyurethane compositions described above includes catalysts well known in the art; Accelerators and amines are used.

Can be used in place of polyurethane elastomer or polyurethane foam materials The elastomer and foam are General Electric (Silic). one Products Division, Waterford, Ne silicone elastomer manufactured by York 121BB, e.g. RTU, 627 and silicone foam RTF, 762 and RTF, 8510. These scenes Silicone elastomers and foams exhibit excellent flame retardant properties. silicone elas Tomer/foam products are made from the previously described polyurethane elastomer/foam. Manufactured in the same way as products.

In one particularly preferred embodiment of the invention, a textile-coated steel mesh reinforced microporous foam When the frame is molded, a hollow case is formed in which the lower 10 mm of the outer periphery is not covered with textile material. The hollow case is then placed on a 10 mm plywood board for this purpose. I decided to staple it to the edge of the plywood through the bottom 10mm of the hollow case. Therefore, the attached plywood can be made flame retardant by treating it with a well-known flame retardant for wood. It can be done. Next, the lower edge of the fabric-coated wire reinforced hollow case was Cover the lower edge of the hollow case with the fabric that extends beyond +v+, and then Staple the plywood to the underside of the plywood by rows. Fasten with staples like this The bristle cover stretches approximately 25 to 30 inches on the plywood substrate. Then excess wool Trim. The stable passes through the wire reinforcement and secures the seat molding to the plywood. Attach it.

As an example, two foamable plastic material (elastomer) formulations were selected. workman The tensile strength of the elastomer is called No. 1, and the tensile strength of the elastomer is the same as that of the wool material. The tensile strength of the wool fabric is slightly higher than that of the second elastomer. I chose it to be slightly lower than that.

Elastomer No. 1 Shore A hardness 45-50 Elastomer No. 2 Shore A hardness 3 35-40 To maintain flexibility, Australian Patent No. 41933 Flexible gold m (Hunter Wire P) with the pitch described in the book (supplied from products) was selected. This allows for an optimal elastomer thickness of 5 to 6 cm. To tolerate. Its purpose is to reduce hardness and increase flexibility. The features of this invention Another feature is that the material is designed to achieve maximum bond strength between the elastomer and the woolen fabric. It is a matter of choosing the price.

Test samples were prepared and the peel strength of the elastomer was evaluated.

The test sample 5II1m x 6011II+ x 240IllllI+ is Hunters Reinforced with wire rods supplied by WireProducts and covered with pure wool fabric did. Subject the sample to the standard "T" peel test as outlined in Attachment Sheet 1-Q, P, 5. Ta.

Test samples of elastomer No. 1 Shore A45-50 have a peel strength of 120-150. Newton was shown.

Test samples of elastomer No. 2 Shigor A35-40 had a peel strength of 65-90 nu. It showed a ton.

Some of the tests on elastomer #1 test samples showed that the hair fibers were torn. This breakage pattern, in which hairs that have ended prematurely are torn off without peeling, is ideal. . This is because the elastomer and bond are stronger than the tensile strength of the fabric.

For elastomer number 2, the sample delaminated uniformly behind the bond line.

In this case, the fabric-elastomer bond line is stronger than the tensile strength of the elastomer. stomach.

From the perspective of fracture resistance, sample No. 1, which is made of a harder material, seems to be the most preferable. , the tests conducted so far have shown that both elastomers perform equally well under the test conditions; Elastomer No. 2 is preferred for its extra flexibility and softer release. and showed. Softer material with edgeless seat free from destruction where tearing begins Soft elastomer No. 2 is the same as elastomer No. 1. It is difficult to start tearing. To start tearing, first create a triangle Make a cut in the fabric cover, then dig out a corner or I have to open up. In trials this proved to be very difficult.
