The present application relates to the technical field of rubber, in particular to a kind of giant engineering machinery tire anti-split body rubber composition and preparation method thereof. With 100 parts by weight of natural rubber component as benchmark, further comprising the following components: natural rubber 100 parts, carbon black 40-50 parts, zinc oxide 6-8 parts, cobalt salt 0.2-0.4 parts, antioxidant 2246 0.5-1 part, antioxidant S-TMQ 0.2-1.0 parts, N,N'-4,4'-diphenyl methane bismaleimide 0.5-1.5 parts, insoluble sulfur 8-12 parts, accelerator 0.3-0.7 parts, anti-scorching agent 0.05-0.15 parts. The present application solves the shortcomings of lower adhesive property of body rubber and insufficient anti-splitting ability of existing technology under harsh road conditions and hot and humid, steam, salt water environment, greatly reduces the occurrence probability of body delamination and bead bulging under hot and humid environment in Southeast Asia, improves the anti-splitting ability of body rubber, and ensures the service life of giant tire under high load operation.

This invention provides an extruder for wires with smooth and uniform heating, comprising a body, a die head, a neck, a barrel, a heater, a conduit, and a pump. The body encloses the barrel, which contains a screw. The body includes a heating zone and an extrusion zone. The heater is connected to the heating zone via a conduit. The die head is connected to the extrusion zone via the neck. The heating zone has a feed inlet, and the die head has a discharge outlet. Silicone oil is introduced into the heater, and the heated silicone oil is pumped into the heating zone. Existing silicone oil in the heater is pumped back to the heater, thus achieving constant temperature heating. The temperature fluctuation within the barrel is within 1°C, resulting in more uniform material heating, more stable plasticization, and a more stable material flow. This reduces common problems such as old rubber and bulging, leading to higher precision products with better electrical performance and appearance, offering significant advantages in the production of high-frequency data cables.

The utility model discloses a kind of geothermal-resistant impregnated paper laminated solid wood composite floor, including strip-shaped floor body, including by upper to lower sequentially arranged impregnated film paper, high-density fiberboard, plywood and single bottom plate, the plywood includes by upper to lower sequentially arranged multilayer wood board, and the topmost layer wood board in multilayer the wood board is first layer wood board, the conduit of the first layer wood board is distributed along the length direction of wood floor, and the pipe hole of the conduit of the first layer wood board is towards the broad side of the floor body.The pipe hole of conduit is towards the broad side of the floor body, when air moisture content is higher, the area of pipe hole exposed in first layer wood board can be reduced, plywood water absorption is reduced, thereby controlling wood floor water absorption when air humidity is larger, reduce the bulging phenomenon of wood floor.

This utility model discloses an interlocking block slope protection for a plain reservoir dam, comprising several evenly arranged slope protection blocks. Each slope protection block has multiple elongated openings along its transverse direction on its front side, extending longitudinally through the block. Multiple longitudinal drainage pipes are installed within each slope protection block, with both ends of each pipe connected to the outside. Furthermore, the drainage pipes are arranged in a matrix along the longitudinal direction. Even further, a connecting pipe is provided between two adjacent drainage pipes in the transverse direction. Furthermore, a rubber pad layer is provided on the outer surface of each slope protection block. Even further, the surface of the rubber pad layer has several raised points. This utility model, by installing multiple drainage pipes inside the slope protection block and providing a rubber anti-slip layer on the outer side, enables the slope protection block to drain rainwater quickly and efficiently without losing stability under temperature changes.

The present application relates to a kind of shoe material accessories tape coating machine, including feeding station, coating station, blanking station and transfer mechanism, coating station includes workbench, auxiliary edge covering mechanism, main edge covering mechanism, auxiliary edge covering mechanism is located at the both ends of workbench position, main edge covering mechanism includes positioning plate and coating plate, positioning plate and coating plate are slidably connected, positioning plate and workbench are slidably connected, positioning plate and coating plate are respectively connected with corresponding cylinder, the face of positioning plate and coating plate towards inside is equipped with the arc surface groove consistent with the shape of accessory body;The auxiliary edge covering mechanism includes flange and the third cylinder of driving flange swing;Vacuum hole is distributed on the workbench. Through the positioning of accessory body and adhesive tape of feeding station and the coating operation of coating station to the accessory to be coated, it is efficient, the yield is high, greatly reduces the occurrence of adhesive tape fold or bulge in coating process, and the soft adhesive tape is evenly folded into tail.
