Description

Technical Field

[0001] The present invention relates to the technical field of anti-skid plates, and in particular to a composite fisheye anti-skid plate for complex road surfaces in multiple scenarios and a preparation method thereof. Background Art

[0002] Traditional concrete pavement technology has a series of problems, including long time, high cost, large workload, and the transportation of materials and the deployment of paving machinery and equipment. In the actual paving process, large vehicles have to roll over the road surface many times, and the long-term load will inevitably cause the newly paved road surface to break and collapse. On the one hand, the construction waste left at the concrete pouring project site needs additional cleaning work. On the other hand, if other engineering construction is required, the paved site road surface needs to be broken for the second time, which not only requires a large amount of capital investment, but also causes a waste of materials and resources, which does not meet the requirements of green construction and sustainable development.

[0003] Concrete pavement technology generally adopts mechanized paving. Therefore, in some special application scenarios, concrete pavement cannot be paved on site due to site limitations, such as industrial plants, production workshops, corridors in public places and other places with limited space. In addition, in some important places such as airports, stations, and disaster relief sites, when large-scale road damage is caused by man-made or natural disasters, rapid repairs are required. However, the existing concrete pavement construction progress is slow, the road quality cannot be guaranteed, the construction site causes certain damage to the environment, and the closed construction puts pressure on normal traffic. In addition, during the repair process, a large number of construction personnel are required to participate on site, the work efficiency is low, and the on-site construction order is difficult to maintain. In addition to some ground application scenarios, it is more difficult to lay tools for rapid pavement in complex underground scenes such as coal mine tunnels. The actual road surface in the coal mine tunnel is wet, has high pH, ​​and is uneven, which puts higher requirements on the anti-slip property and simple paving of the road panel.

[0004] Therefore, it has become an urgent need to study a technology to find a low-cost, easy-to-operate anti-skid plate for the road to solve the problems of high cost and long construction period of traditional cement concrete pavement construction, to achieve lightweight, anti-slip, fast paving, and reusability in multiple scenarios, to reduce the inconvenience caused by slippery roads, to protect the personal safety of personnel, and to bring convenience to construction.

[0056] Example 1

[0057] like Figure 1 The figure shows the structure of the composite fisheye anti-skid plate for complex roads in multiple scenarios. The main body of the rubber anti-skid base is plate-shaped with a thickness of 3-6mm. It is located in the lower layer of the anti-skid plate and is mainly used for tire anti-skid and shock absorption. In order to further improve the corrosion resistance and anti-skid performance of the anti-skid plate, a metal substrate layer with fisheye-shaped convex holes is adhered to the upper surface of the rubber anti-skid plate body. The length of the metal substrate layer with fisheye-shaped convex holes is 800-1000mm, the width is 500-800mm, the thickness is 2-4mm, and the number of fisheye-shaped convex holes is 280-300. The fisheye-shaped convex holes are mainly used to fit closely with the outside of the tire to prevent the tire from slipping. During the processing, the rubber anti-slip base and the connecting surface of the fish-eye convex hole metal substrate layer are fixedly connected by an adhesive. When the metal substrate layer is a galvanized iron plate, the galvanized layer on the back of the galvanized iron plate needs to be scraped off before applying the adhesive, and then the adhesive is evenly applied to the back of the fish-eye convex hole metal substrate layer with a brush. The raw rubber is heated and pressurized by a flat vulcanizer and kept warm for a certain period of time to become mature rubber that adheres to the fish-eye convex hole metal substrate layer.

[0058] like Figure 2 and Figure 3 The figure shows the physical picture and cross-sectional view of the composite fisheye anti-skid plate for complex roads in multiple scenarios. The raw rubber becomes mature rubber after pressure-maintaining heating, and the softened mature rubber is evenly filled in the fisheye-shaped convex holes. In addition, the rubber anti-skid base and the galvanized iron plate layer with fisheye-shaped convex holes are firmly bonded to form a whole under the action of the adhesive. In particular, the rubber layer evenly covers the metal edge of the fisheye-shaped convex hole, effectively preventing the convex hole edge from damaging the vehicle tire, etc., which is safer, and the overflowed rubber layer also has a certain anti-skid and shock-absorbing effect.

[0059] Example 2

[0060] Take 60 parts of rubber, 35 parts of reinforcing agent, 5 parts of activator, 3 parts of vulcanizer, 2 parts of vulcanization accelerator, 5 parts of antioxidant, 3 parts of rubber wear agent, and 3 parts of flame retardant to prepare raw rubber. Accurately weigh 3.5kg of raw rubber, spread it flat in the mold of the rubber vulcanizer, and place the fisheye-shaped convex hole galvanized iron plate coated with adhesive flat on the raw rubber. The size of the fisheye-shaped convex hole galvanized iron plate is 1000mm, the width is 500mm, the thickness is 4mm, and the number of fisheye-shaped convex holes is 300. After the raw rubber is heated and pressurized by the flat vulcanizer, it is kept warm at 160℃ and 7MPa for 40min to fully mature the raw rubber with good fluidity and fully fill the fisheye convex holes. After the insulation time is over, it is naturally cooled to room temperature to obtain a composite fisheye anti-skid plate for complex roads in multiple scenes.

[0061] Example 3

[0062] Take 65 parts of rubber, 40 parts of reinforcing agent, 3 parts of activator, 2 parts of vulcanizer, 1 part of vulcanization accelerator, 8 parts of antioxidant, 5 parts of rubber wear agent, and 4 parts of flame retardant to prepare raw rubber. Accurately weigh 3.5kg of raw rubber, spread it flat in the mold of the rubber vulcanizer, and place the fisheye-shaped convex hole galvanized iron plate coated with adhesive flat on the raw rubber. The size of the fisheye-shaped convex hole galvanized iron plate is 1000mm, the width is 500mm, the thickness is 4mm, and the number of fisheye-shaped convex holes is 300. After the raw rubber is heated and pressurized by the flat vulcanizer, it is kept warm at 155℃ and 8MPa for 35 minutes to fully mature the raw rubber with good fluidity and fully fill the fisheye convex holes. After the insulation time is over, it is naturally cooled to room temperature to obtain a composite fisheye anti-skid plate for complex roads in multiple scenes.

[0063] Example 4

[0064] In this embodiment, different anti-skid plate samples were subjected to combustion test, wear performance and mechanical property test. The test results are as follows: Figure 4 and Figure 5 shown. Figure 4 (a) is the flame combustion time diagram of different samples after a 10s combustion test. Figure 4 (b) is the flame retardant grade diagram of different samples. Figure 4 It can be seen that all nine samples have excellent flame retardant properties. The flame burning time of the rubber anti-skid base strip containing flame retardant is very short, within the range of 0.7-1.5s, and there is no obvious droplet phenomenon. According to the flame retardant grades of different samples determined by the combustion results, it is found that the flame retardant grades of all samples are relatively high, reaching the V-0 grade, indicating that the rubber anti-skid base in the anti-skid plate of the present invention has a good flame retardant effect. Figure 5 (a) is the test result of the wear performance of the rubber anti-skid substrate. The wear resistance of rubber is an important parameter to characterize rubber products. The wear performance of the rubber anti-skid substrate was tested through a wear experiment. The results showed that all 9 samples showed good wear resistance, and the wear volume was controlled within 0.2 cm 3 The following illustrates that the rubber anti-skid substrate used has a strong effect of resisting friction and a small material loss, which indirectly indicates that the rubber anti-skid substrate of the present invention has a long service life. The good wear resistance may be attributed to the presence of a large number of cis structures in the rubber structure, and a large number of CC single bonds in the molecule that can undergo internal rotation, which enhances the elasticity and wear resistance of the rubber. Figure 5 (b) is the mechanical properties test result of the rubber anti-skid base. As can be seen from the figure, the tensile strength of the 9 samples is relatively high, with the highest reaching 17.3MPa. The life of the rubber anti-skid base is related to the tensile strength. A higher tensile strength can significantly extend the service life of the rubber anti-skid base.

[0065] Example 5

[0066] This embodiment provides a method for laying a composite fisheye anti-skid plate for complex roads in multiple scenarios. The installation is carried out according to the actual width and length of the road surface. Several anti-skid plates are spliced ​​side by side in the extension direction of the road surface. Several adjacent anti-skid plates are fixed to the metal frame through rivet nuts as anti-skid panels. The metal frames are laid and installed through a bolt-type connection structure. Figure 6 The figure shows a composite fisheye anti-skid plate pavement for complex pavement in multiple scenarios. The metal frame is used as the bottom support of the composite fisheye anti-skid plate for complex pavement in multiple scenarios, so that the anti-skid plate has multiple properties such as anti-corrosion, flame retardant, anti-skid, and shock absorption. In addition, this embodiment has been subjected to multiple rolling tests. The experimental results show that after the road panel was rolled over by an unloaded 3.5t forklift for multiple times, the composite fisheye anti-skid plate was intact, the fisheye-shaped convex holes on the surface did not collapse or deform, and the rubber base and the galvanized iron plate layer did not separate and were firmly bonded. Due to the filling of rubber in the fisheye-shaped convex holes, there were no scratches on the surface of the forklift tire after multiple rolling, indicating that there was no wear damage to the tire.
