Description

Technical Field

[0001] This utility model relates to the field of epoxy resin board technology, specifically to environmentally friendly epoxy resin board. Background Technology

[0002] Epoxy resin boards are sheet products made of epoxy resin, also known as insulating boards. Epoxy resin is a high molecular polymer containing two or more epoxy groups in its molecule. It can react with a curing agent to form an insoluble and infusible three-dimensional network structure polymer. Epoxy resin boards are usually made of epoxy resin, curing agent and other materials, and have excellent performance and a wide range of applications.

[0003] While existing epoxy resin boards possess a certain degree of hardness, their relatively loose structure and limited impact and wear resistance prevent them from effectively dispersing and bearing bending stress. This structural defect makes it difficult for epoxy resin boards to effectively disperse local stress concentration when subjected to bending stress, thus significantly increasing the risk of plastic deformation and brittle fracture. Especially under dynamic load conditions, microcracks inside the material can propagate rapidly, ultimately leading to catastrophic failure.

[0004] Therefore, this utility model provides an environmentally friendly epoxy resin board to solve the above problems. Utility Model Content

[0009] As a preferred technical solution of this application, the outer wall of the epoxy resin composite core is sprayed with hydrophobically modified nanocellulose, and the epoxy resin panel is a composite epoxy resin layer containing boron nitride nanosheets.

[0010] As a preferred technical solution of this application, the fiber reinforcing layer is made of carboxymethylated nanofibers, and the -COOH content in the carboxymethylated nanofibers is 20%. The aerogel particle finishing layer is made of silica aerogel particles, and the aerogel particles have a particle size of 50nm.

[0011] As a preferred technical solution of this application, the outer surface of the aerogel particle decorative layer is uniformly provided with wavy patterns, the depth of which is 0.2 mm and the wavelength of which is 8 mm.

[0012] The beneficial effects of this application are as follows:

[0013] This utility model, through a sandwich structure composed of a honeycomb core material and an epoxy resin panel, can significantly improve the overall bending stiffness and compressive strength.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, this utility model provides an environmentally friendly epoxy resin board, including an epoxy resin composite core material 1. The epoxy resin composite core material 1 has uniformly formed honeycomb holes 11, and vertical reinforcing ribs 12 are interlocked between adjacent honeycomb holes 11. Epoxy resin panels 2 are bonded to both sides of the epoxy resin composite core material 1, and a fiber reinforcing layer 3 is bonded to the other side of the epoxy resin panel 2. An aerogel particle finishing layer 4 is bonded to the other side of the fiber reinforcing layer 3. The honeycomb holes 11 result in a low density and high porosity for the epoxy resin composite core material 1, significantly reducing the weight of the epoxy resin board while maintaining structural strength. Furthermore, the cooperation between the epoxy resin composite core material 1 and the epoxy resin panel 2 creates a sandwich structure that significantly improves the overall bending stiffness and compressive strength. Its honeycomb hexagonal unit structure, by bearing shear stress and dispersing external loads, reduces the risk of deformation of the epoxy resin board, effectively improving its bending stiffness and compressive strength, and indirectly increasing its service life.

[0023] Furthermore, the honeycomb hole 11 has a tapered aperture design, with an upper surface diameter of 5mm and a lower surface diameter of 3mm. The tapered aperture gradient design brings greater flexibility and a wider performance range to the honeycomb, making its load transfer more precise and flexible, avoiding excessive stress concentration, and preventing deformation of the plate.

[0024] Furthermore, the vertical reinforcing rib 12 is made of polylactic acid fiber, with a diameter of 1 mm and a spacing of 10 mm between adjacent vertical reinforcing ribs 12. Polylactic acid fiber, also known as polylactide, is a polyester polymer obtained by polymerization of lactic acid as the main raw material. It is a new type of biodegradable material. Through the vertical reinforcement of the vertical reinforcing rib 12, the interlayer shear failure of the epoxy resin composite core material 1 is effectively avoided, thereby improving its shear dispersion stability.

[0025] Furthermore, the outer wall of the epoxy resin composite core material 1 is sprayed with hydrophobically modified nanocellulose to prevent resin from penetrating the epoxy resin composite core material 1 and play a good barrier role. The epoxy resin panel 2 is a composite epoxy resin layer containing boron nitride nanosheets. Through the addition of boron nitride nanosheets, the epoxy resin panel 2 has good heat resistance, so that the epoxy resin panel 2 can still maintain its structural and performance stability at high temperatures.

[0026] Furthermore, the fiber reinforcement layer 3 is made of carboxymethylated nanofibers, and the -COOH content in the carboxymethylated nanofibers is 20%. The aerogel particle finishing layer 4 is made of silica aerogel particles, and the particle size of the aerogel particles is 50nm. Silica aerogel particles are a nanoporous solid material, which consists of a three-dimensional network structure composed of silica nanoparticles. The internal porosity exceeds 90%, and the density can be as low as 3 kg / m³. It has extremely low thermal conductivity, high specific surface area, and excellent adsorption performance. As a finishing layer, it can improve the anti-pollution ability. At the same time, it has excellent chemical stability and high temperature stability, which can effectively improve the wear resistance and weather resistance of the board surface and reduce the influence of external factors such as temperature, light, and oxidation in the air on the board surface.

[0027] Furthermore, the outer surface of the aerogel particle finishing layer 4 is uniformly covered with wavy patterns, with a depth of 0.2 mm and a wavelength of 8 mm. The coefficient of friction is increased from 0.4 to 0.7, which enhances the friction between the surfaces of the board and increases the sliding resistance. Therefore, the board is less likely to slide relative to each other during use. At the same time, the wavy patterns can reduce the surface temperature through light refraction, further improving its heat insulation performance.

[0028] Working principle: First, the plate is assembled. Through the cooperation of the honeycomb holes 11 and the vertical reinforcing ribs 12, the plate can withstand shear stress when under pressure, disperse external loads, and reduce the risk of epoxy resin board deformation. Furthermore, the vertical reinforcing ribs 12 between the honeycomb holes 11 can further prevent interlaminar shear failure, ensuring that the plate can withstand shear stress and disperse external loads, thereby improving the service life and stability of the plate.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
