Description

Technical Field

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0029] Example:

[0030] See also Figure 1-5 A composite PVC sheet, the PVC sheet comprising a sheet base 4, a top layer 1 is arranged on the top of the sheet base 4, a protective component is arranged between the top layer 1 and the sheet base 4, and a protective layer 5 is arranged on the lower surface of the sheet base 4;

[0031] The protective component includes a buffer layer 2 and an elastic layer 3. The buffer layer 2 is provided on the upper surface of the elastic layer 3. The material of the buffer layer 2 is a polyethylene foam board. The polyethylene foam board is a foam board made of polyethylene as a raw material. The polyethylene foam board has low density, light weight, is easy to carry and install, has certain flexibility and elasticity, and can effectively buffer impact force.

[0032] The elastic layer 3 is made of a rubber sheet, which is a plate-like material made of rubber. The rubber sheet has good elasticity and can return to its original shape after being stressed, thus playing a role in buffering and shock absorption.

[0033] A plurality of rhombus tubes 21 are further arranged inside the buffer layer 2, and internal reinforcing ribs 22 are arranged inside the rhombus tubes 21, and the rhombus tubes 21 are hollow in design;

[0034] The material of the diamond tube 21 is silicone, which has good softness and elasticity and is not easy to deform or break;

[0035] The material of the internal reinforcement rib 22 is a cork board. The cork board is a plate-shaped material made of cork bark. It is mainly made by processing and processing the bark of the cork tree. The cork board has low density and light weight. The cork board has a certain elasticity, which can reduce impact force and reduce damage.

[0036] When the PVC sheet is impacted, the rhombus tube 21 will be deformed, which will cause the internal reinforcing ribs 22 to be deformed. The material properties of the rhombus tube 21 and the internal reinforcing ribs 22 can buffer the impact force and reduce damage.

[0037] A plurality of second elastic ribs 32 are disposed transversely inside the elastic layer 3, and a plurality of first elastic ribs 31 are disposed longitudinally inside the elastic layer 3. The first elastic ribs 31 and the second elastic ribs 32 are both made of polyurethane plates. The polyurethane plates have good elasticity and can return to their original shape after being subjected to force. They have good buffering and shock absorbing effects, and are used to improve the buffering and shock absorbing effects of the PVC plate.

[0038] The top layer 1 is composed of a wear-resistant layer 11, a reinforcement layer 12 and an explosion-proof layer 13. The wear-resistant layer 11 is made of a carbon fiber board, which is a composite material board composed of carbon fiber and resin. The carbon fiber board has the advantages of high surface hardness and excellent wear resistance, and is suitable for high-strength and wear-resistant occasions.

[0039] The material of the reinforcement layer 12 is a marble slab. Marble has a high hardness and can resist a certain degree of wear and pressure. It has high hardness and good wear resistance.

[0040] The material of the explosion-proof layer 13 is glass fiber reinforced plastic, which has high strength and can withstand a certain degree of impact and pressure, thereby reducing the damage caused by the explosion impact. It has good impact resistance and can not break when impacted, avoiding fragments from splashing, and reducing the risk of explosion;

[0041] The material of the protective layer 5 is a titanium alloy plate. Titanium alloy has good wear resistance and is suitable for occasions requiring wear resistance. It has good corrosion resistance and can resist corrosion from most acids, alkali media and seawater, and can better protect the bottom of the PVC plate.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
