ようになっていた。In general, this type of pressure belt for surface pressure nip press (hereinafter referred to as "pressure belt") has polyurethane, acrylonitrile butadiene, or It is made of a layer of synthetic resin such as urethane rubber. Thermosetting resin was mainly used for the synthetic resin layer (Japanese Patent Publication No. 63-15398, Japanese Patent Publication No. 63-384).
77). The pressure belt is interposed between the wet paper paper sheet and the press shoe, so that water can be squeezed without pressurizing the wet paper paper.

You will be driving in close contact with the In this case, water in the wet paper web sheet is squeezed out through the felt and retained within the base fabric of the pressure belt. Therefore, when the void volume (void volume) of the base fabric is small, the water squeezing ability decreases.

であったとしても、樹脂が所定の硬度に達するまでに長
時間を要するといった問題点があった。In the conventional pressure belt for surface press mentioned above, thermosetting resin was mainly used for the synthetic resin layer.
There were various defects in the manufacturing process. That is, ■If the viscosity of the resin liquid is lowered, it will take longer to complete curing, which will cause too much penetration into the base fabric and reduce the void volume of the base fabric.■On the other hand, if the viscosity of the resin liquid is increased, Bubbles are more likely to form within the resin layer, and sufficient penetration depth into the base fabric cannot be obtained.As a result, the adhesive strength is insufficient and cracks and peeling are more likely to occur during use. , Durability deteriorates (1) Even if the viscosity of the resin liquid is appropriate, there is a problem that it takes a long time for the resin to reach a predetermined hardness.
この発明は上記の点に鑑み、耐久性に冨み、しかも均一
な樹脂層を有する面圧プレス用加圧ベルト及びその製造

By drying and curing, it is possible to provide a pressure belt for surface press that can be manufactured in a short time and has a resin layer with desired characteristics.

Further, the viscosity of the resin liquid supplied from the feeder 4 is appropriately determined depending on the structure of the base fabric 1, curing conditions, and the like.

It is set in. Although the curing time of the resin depends on the manufacturing conditions, it is usually about several seconds to several minutes. Further, the ultraviolet lamp 5 has a base fabric made of slimy resin.
When the irradiation reaches a predetermined depth from the surface, the irradiation is controlled for a predetermined period of time.

In this case, since there is already a resin layer on the opposite side, making it difficult for bubbles to come out, the viscosity of the resin liquid should be lowered to about 3000 cps, and the curing time should be set a little longer (for example, about 1 degree). It is desirable to leave it there.

Apply. At this time, the amount and viscosity of the applied resin liquid are adjusted appropriately according to the structure of the base fabric 1, and the resin liquid is applied onto the base fabric 1 to a thickness of 0.1 to 1.
．． A resin coat of about 0 mm is formed. Once this resin coat has penetrated into the base fabric 1 to an appropriate depth, it is irradiated with ultraviolet light by an ultraviolet lamp 5 disposed behind the main cylinder 2, and hardens within a short time to cover the surface of the base fabric 1. A resin layer having a predetermined hardness is formed.

つ短時間に製造される。As described above, the method for manufacturing a pressure belt for a surface press according to the present invention is to apply an ultraviolet curable resin liquid to one or both sides of a base fabric, and when the resin liquid reaches a predetermined penetration level. Since the synthetic resin layer is formed by curing treatment by ultraviolet irradiation, it is possible to obtain a pressure belt for a surface press with small variations in the depth of penetration of the resin into the base fabric. Therefore, the variation in void volume of the pressure belt with a synthetic resin layer formed on one side of the base fabric is also reduced.
A pressure belt for a surface press having desired water squeezing properties can be manufactured reliably and in a short time.

熱硬化性樹脂では必須となる溶剤を使用せずに済むので
、作業環境の改善と公害防止にも寄与する。Since the coating and curing process can be performed while controlling the viscosity and permeability of the resin, the adhesive strength between the resin layer and the base fabric is high, and it is possible to prevent bubbles from remaining in the resin layer. Additionally, since it does not require the use of solvents, which are essential with conventional thermosetting resins, it contributes to improving the working environment and preventing pollution.
この結果、製造工程の効率と安全性に優れ、しかも搾水
特性と耐久性の良好な面圧プレス用加圧ベルトを提供で
きるという優れた硬化を奏するものである。As a result, it exhibits excellent curing, making it possible to provide a pressure belt for surface pressure presses that is excellent in efficiency and safety in the manufacturing process, and also has good water squeezing properties and durability.
