Photocatalyst can directly carry out redox to the object that adsorbs to the surface after the absorbed light energy, thereby promotes the utility model discloses a kraft paper sticky tape's degradation, simultaneously yarn 21 of yarn layer 2 adopts warp and weft criss-cross structure still can effectual assurance kraft paper layer 1's light transmissivity to further department promotes photocatalyst's redox reaction, promotes the efficiency of degradation promptly.
As shown in fig. 5, the manufacturing process of the high tensile kraft paper adhesive tape includes the following steps:
the kraft layer 1 and the yarn layer 2 are respectively connected to a traction device (not shown in the drawing) after passing through two heat-conducting rollers 9 of a composite device, the kraft layer 1, the yarn layers 2 and the kraft layer 1 are sequentially arranged in a gap between the two heat-conducting rollers 9 of the composite device from bottom to top, meanwhile, the yarn layers 2 pass through a flat plate 5 before entering the composite device, the yarn layers 2 are conveyed on the flat plate 5 before entering the composite device, and the kraft layer 1 below the yarn layers is in parallel traction movement under the flat plate 5; the process of traction movement of each kraft layer 1 and each yarn layer 2 comprises the following steps:
s1: the yarn layer 2 moves on the flat plate 5 before entering the compounding device, the surface of the yarn layer 2 on the flat plate 5 is coated with compound glue, and the coated compound glue has a distance with the boundary of the yarn layer 2, so that the compound glue can be prevented from overflowing after the kraft layer 1 and the yarn layer 2 are compounded, and the compound glue coating mode can promote the rhombic meshes of the yarn layer 2 to be filled with bonded materials (namely the compound glue) so as to improve the bonding firmness after the subsequent yarn layer 2 and the kraft layer 1 are compounded. Meanwhile, the traction moving speed of the kraft paper layer 1 and the yarn layer 2 is 10-300m/min, and the filled composite glue can be dragged to move in each rhombic grid of the yarn layer 2 at the speed, so that the phenomenon that the composite glue cannot be attached due to the excessively high moving speed is avoided;
further, in the case where the yarn layers 2 have a plurality of layers, each of the yarn layers 2 is drawn vertically downward or vertically upward, passed around the guide roller 8, and then horizontally drawn onto the flat plate 5 in a state of being superimposed. The guide rollers 8 for drawing the yarn layers 2 are sequentially arranged along the moving direction of the yarn layers 2, and the positions of the yarn layers 2 moving on the flat plate 5 for coating the composite adhesive are all positioned behind the guide rollers 8, namely the yarn layers 2 firstly bypass the guide rollers 8 and then are coated with the composite adhesive, and meanwhile, the positions of the yarn layers 2 positioned above and provided with the coating machine 6 are closer to the compounding equipment than the positions of the yarn layers 2 positioned below and provided with the coating machine 6, so that the yarn layers 2 can be respectively embedded in one layer of composite adhesive, and in the process of drawing and moving on the flat plate 5 after the yarn layers 2 are coated with the composite adhesive, the composite adhesive coated on the yarn layers 2 can be mutually fused, so that the yarn layers 2 form a whole body which is overlaid and bonded;
the underlying kraft layer 1 is moved horizontally under the plate 5 and is engaged under the end of the plate 5, so that the yarn layer 2 coated with the composite adhesive is overlapped on the underlying kraft layer 1 after moving out of the plate 5;
in addition, the flat plate 5 can be provided with upward bent baffles (not shown in the drawing) at both sides of the yarn layer 2 in the conveying direction, the baffles are used for blocking the compound glue to prevent the compound glue from flowing out towards both sides, and meanwhile, a receiving groove (not shown in the drawing) can be arranged below the flat plate 5 and is used for receiving a small amount of compound glue which overflows downwards from the front end and the rear end of the flat plate 5 in the conveying direction of the yarn layer 2 so as to be recycled.
S2: when each yarn layer 2 is dragged and moved between the two kraft layers 1 and is not dragged to the composite equipment, preheating is carried out, wherein the preheating temperature is 30-200 ℃, the preheating mode can be that electric heating pipes 91 are arranged on the kraft layer 1 positioned on the upper layer and under the kraft layer 1 positioned on the lower layer, so that a high-temperature environment is formed to preheat the composite glue on the yarn layer 2 between the two kraft layers 1, the composite glue tends to be pasted, and the phenomenon that the composite glue cannot be bonded when entering the composite equipment is avoided.
S3: when the kraft layer 1 and the yarn layers 2 move to the composite device, the heat-conducting rollers 92 of the composite device heat the composite glue on each layer, and the two heat-conducting rollers 9 of the composite device press and compound the kraft layer 1 and the yarn layers 2, so that the composite glue coated on the yarn layers 2 forms the bonding layer 4 for bonding the adjacent yarn layers 2 and the kraft layer 1, thereby forming the kraft layer 1, the plurality of yarn layers 2 and the kraft layer 1 which are sequentially fixed and bonded.
