Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastics, in particular to a high-temperature resistant glass fiber reinforced plastic gel coat plate. Background Art

[0002] FRP is a glass fiber reinforced thermosetting resin composite material. Gel coat is a special resin used to make the gel coat layer of FRP products. It can improve the glass fiber, enhance the appearance quality of unsaturated polyester resin-based FRP products, and protect the material of the structural layer from erosion by external environmental media.

[0003] When using traditional FRP gel coat boards, the thermal insulation capacity is usually improved by increasing the thickness of the FRP gel coat boards, reducing the adverse effects of heat transfer on the FRP gel coat boards, and thus extending the service life of the FRP gel coat boards.

[0004] However, the existing FRP gel coat panels have poor actual high temperature resistance, and the improvement in thickness design can only slow down the speed of heat transfer inward or loss outward to a certain extent, which leads to a poor experience in the application of FRP gel coat panels and is difficult to meet actual usage needs. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art such as poor high temperature resistance, fast heat transfer inward or outward loss, poor application experience, and difficulty in meeting actual use needs, and to propose a high temperature resistant fiberglass gel coat board.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a high-temperature resistant fiberglass gel coat board, comprising an inner lining layer, a reinforcement layer and a gel coat layer, an insulation layer is provided on the top of the inner lining layer, a plurality of filling grooves are opened on the top of the insulation layer, and the interior of the filling grooves is filled with heat-insulating fillers.

[0007] Preferably, the reinforcement layer is arranged above the thermal insulation layer, the gel coat layer is arranged above the reinforcement layer, and the outer sides of the lining layer, thermal insulation layer, reinforcement layer and gel coat layer are coated with corrosion-resistant edging.

[0008] Preferably, the top of the gel coat layer is coated with a high temperature resistant coating, and the thickness of the gel coat layer is 0.5 mm.

[0009] Preferably, the thickness of the reinforcement layer is 10 mm, and the thickness of the lining layer is 3 mm.

[0010] Preferably, the filler grooves are distributed on the insulation layer in a honeycomb shape.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, a basic FRP gel coat board is composed of an inner lining layer, a reinforcement layer and a gel coat layer. The thermal insulation capacity of the FRP gel coat board is enhanced by the thermal insulation layer. At the same time, thermal insulation fillers are filled on the thermal insulation layer through the filler groove, thereby improving the thermal insulation, high temperature resistance and thermal insulation performance of the FRP gel coat board.

[0013] 2. In the present invention, the heat transfer inward and outward loss is blocked by the heat-insulating filler in the filler groove and the thermal insulation layer, thereby effectively enhancing the high temperature resistance and thermal insulation performance of the FRP gel coat board itself, greatly reducing the heat transfer efficiency on the FRP gel coat board, thereby extending the service life of the FRP gel coat board, optimizing the application experience of the FRP gel coat board, and enabling it to meet actual usage needs.

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] See also Figures 1-4The utility model provides a technical solution: a high-temperature resistant glass fiber reinforced plastic gel coat board, comprising an inner lining layer 1, a reinforcement layer 2 and a gel coat layer 3, an insulation layer 4 is provided on the top of the inner lining layer 1, a plurality of filling grooves 5 are provided on the top of the insulation layer 4, and the interior of the filling groove 5 is filled with heat-insulating fillers 6, the inner lining layer 1, the reinforcement layer 2 and the gel coat layer 3 constitute a basic glass fiber reinforced plastic gel coat board, and the insulation layer 4 enhances the insulation capacity of the glass fiber reinforced plastic gel coat board. The insulation layer 4 is mainly made of ceramic fiber material, which has low thermal conductivity, low heat capacity, excellent chemical stability and thermal stability, outstanding high temperature resistance, and can maintain stability in high temperature environment. Performance, will not decompose or release harmful substances, its fiber structure makes it have a certain flexibility, can adapt to different shapes of glass fiber reinforced plastic gel coat board, and is easy to install and construct, and at the same time, the thermal insulation filler 6 is filled on the insulation layer 4 through the filler groove 5. The thermal insulation filler 6 mainly adopts aerogel material, which has extremely low density and extremely high porosity, and extremely low thermal conductivity. It can effectively prevent the transfer of heat and will not increase the weight of the board too much, thereby improving the thermal insulation, high temperature resistance and thermal insulation performance of the glass fiber reinforced plastic gel coat board, reducing the speed of heat transfer inward and heat loss outward, optimizing the application experience, and meeting actual use needs.

[0022] like Figure 2 and Figure 3 As shown, the reinforcement layer 2 is arranged above the insulation layer 4, and the gel coat layer 3 is arranged above the reinforcement layer 2. The outer sides of the lining layer 1, the insulation layer 4, the reinforcement layer 2 and the gel coat layer 3 are covered with a corrosion-resistant edging 7. The corrosion-resistant edging 7 is used to cover and seal the outer edges of the FRP gel coat board, thereby improving the strength and sealing of the edges, preventing heat from penetrating from the edges, slowing down the speed of heat transfer inward, and further improving the high temperature resistance of the FRP gel coat board in actual application.

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, the top of the gel coat layer 3 is coated with a high-temperature resistant coating 8, and the thickness of the gel coat layer 3 is 0.5 mm. The high-temperature resistant coating 8 can improve the high-temperature resistance of the surface of the fiberglass gel coat board. The high-temperature resistant coating 8 mainly uses ceramic materials, which have a very high melting point and excellent high-temperature resistance. It can withstand temperatures of thousands of degrees. At the same time, it has good wear resistance, corrosion resistance and insulation, and has high hardness, which can effectively protect the surface of the fiberglass gel coat board.

[0024] like Figure 2 and Figure 3 As shown, the thickness of the reinforcement layer 2 is 10 mm, and the thickness of the lining layer 1 is 3 mm. Through reasonable layer thickness design, the overall strength of the FRP gel coat plate can be further improved, while reducing the impact of heat transfer on the FRP gel coat plate.

[0025] like Figure 3 and Figure 4As shown, the filling grooves 5 are distributed in a honeycomb shape on the insulation layer 4. The filling grooves 5 are distributed in a honeycomb shape. The honeycomb structure has a large number of pores and channels, which makes the filling grooves 5 have a larger specific surface area. At the same time, the pores in the honeycomb structure can form an air layer. The thermal conductivity of air is low, which can effectively prevent the transfer of heat. The honeycomb structure has a scattering and absorption effect on sound waves, which can reduce the propagation energy of sound waves, thereby achieving a sound insulation effect.

[0026] The working principle of this embodiment: when in use, first, fill the heat insulation filler 6 into the filler groove 5, and the insulation layer 4 and the heat insulation filler 6 cooperate to form a complete heat insulation structure to reduce the speed of heat transfer inward or outward loss. Then, use the corrosion-resistant edging 7 to cover the edge of the fiberglass gel coat board to prevent heat from penetrating from the edge, and at the same time protect the edge of the fiberglass gel coat board and improve its strength. Finally, a high-temperature resistant coating 8 is coated on the surface of the gel coat layer 3, and the high-temperature resistant coating 8 is used to block the high temperature generated by light, reduce the heat transfer speed, and thereby improve the overall high-temperature resistance of the fiberglass gel coat board, thereby completing the use of the high-temperature resistant fiberglass gel coat board.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
