Problems solved by technology

However, the traditional steel backing board has problems such as high density, inconvenient handling, easy corrosion and rust, and easy deformation; the cement backing board also has problems such as poor toughness and impact resistance, low laying efficiency, and low strength of the connection part; Although FRP plates have low density and good rigidity, they have low bearing capacity and poor aging resistance, which brings a lot of trouble to engineering construction and emergency solutions.

Embodiment 1

[0031] Embodiment 1, in conjunction with attached Figure 1-8 , to further describe the present invention:

[0032] A high-strength composite material backing system mentioned in the present invention includes high-strength composite material plates made of high-density polyethylene (HDPE) and ultra-high molecular weight polyethylene (UHMWPE) through molding process, standard connection module 8, positioning chip The groove cover 9, the outer surface of the high-strength composite material plate is designed with anti-slip lines 2, and its structure is divided into two types: solid structure and back grid-like rib structure, wherein the backing plate of the solid structure is a plane shape 4; The backing plate of the grid-like rib structure adopts a single plate or a composite structure of two plates, wherein the grid-like rib structure on the back is designed as an arrayed square groove 6 and an independent strip groove 7 .

[0033] Among them, the formulation of the high-str...

Embodiment 2

[0046] Example 2: The difference from Example 1 is that the formulation of the high-strength composite material sheet of the present invention is mainly prepared by mixing the following components in weight percentages: 70 parts of high-density polyethylene resin, ultra-high molecular weight polyethylene resin 20 parts of vinyl resin, 10 parts of filler, 2 parts of low shrinkage agent, 5 parts of color paste, 3 parts of release agent, 5 parts of anti-ultraviolet absorber; The molecular weight of the material is 5 million.

Embodiment 3

[0047] Example 3: The difference from Example 1 is that the formulation of the high-strength composite material sheet of the present invention is mainly prepared by mixing the following components in weight percentages: 65 parts of high-density polyethylene resin, ultra-high molecular weight polyethylene resin 18 parts of vinyl resin, 7 parts of filler, 1.5 parts of low shrinkage agent, 3.5 parts of color paste, 2 parts of release agent, 4 parts of anti-ultraviolet absorber; The molecular weight of the material is 3 million, which is different according to the design strength of the backing plate. The higher the strength design requirements of the backing plate, the greater the molecular weight of the material.

Abstract

The invention relates to a high-strength composite base plate system and a preparation process. The high-strength composite base plate system comprises a high-strength composite plate made from high-density polyethylene and an ultra-high molecular weight polyethylene material with a compression molding process, modular connection assemblies and a positioning chip slot cover, wherein anti-slip patterns are designed on outer surfaces of the high-strength composite plate, the high-strength composite plate structurally comprises a solid structure and a back latticed reinforcing rib structure, a base plate of the solid structure is used as a protective plate, a base plate of the back latticed reinforcing rib structure adopts a single-plate structure or a two-plate composite structure, and the back latticed reinforcing rib structure is designed to comprise array type square grooves and independent strip-shaped grooves. The high-strength composite base plate system has the characteristics of fire prevention, flame retardance, light mass, high strength, corrosion resistance, ageing resistance, convenience in mounting, long service life, environment-friendliness and the like and can be used for quick construction of temporary roads, operation platforms and other places.

Description

technical field [0001] The invention relates to a backing plate and a preparation process, in particular to a high-strength composite material backing plate system and a preparation process. Background technique [0002] At present, facing some complex terrain and road conditions, such as swamps, deserts, Gobi deserts, tropical rainforests, tundra areas, etc., there are often problems such as impassability of vehicles and failure of normal installation of equipment. At this time, large paving pads are needed . However, the traditional steel backing board has problems such as high density, inconvenient handling, easy corrosion and rust, and easy deformation; the cement backing board also has problems such as poor toughness and impact resistance, low laying efficiency, and low strength of the connection part; Although FRP plates have low density and good rigidity, their low bearing capacity and poor aging resistance have brought a lot of trouble to engineering construction an...
