Description
Technical Field
The application relates to the field of containers for storing or transporting articles or materials, in particular to a multi-film glass fiber reinforced plastic container.
Background
Glass fiber reinforced plastic containers (FRP containers) are widely used as a structural material in various fields such as chemical industry, petroleum, construction, traffic, etc. due to their high strength, corrosion resistance, light weight, etc. Conventional glass fiber reinforced plastic containers are generally composed of a single layer or multiple layers of glass fiber reinforced materials and a resin matrix, and the structure of the container generally comprises an inner liner layer, a structural layer and an outer protective layer. Since glass reinforced plastic containers are often required to withstand a certain pressure or external impact, an increase in wall thickness is often required to ensure the safety of the container and to prevent leakage or breakage. However, this approach directly leads to an increase in production costs and the mass of the container itself, limiting the widespread use of glass reinforced plastic containers.

Further, the structural layer is bonded by adopting a wet lamination process, the curing temperature is 80-120 ℃, and the curing time is 3-6 hours.
Compared with the prior art, the application has at least one of the following advantages:
1. By using the high-strength glass fiber layer and the light and thin polymer film, the container can be light and thin-walled under the premise of keeping the strength, thereby reducing the dead weight of the container and being convenient for transportation and installation.
2. Through the design of the multi-film structure, the dependence on the wall thickness of the container is reduced, so that the material consumption and the production cost are reduced, and the economy of the glass fiber reinforced plastic container is improved.
3. The combination of the glass fiber and the polymer film of the multi-layer structure effectively enhances the shock resistance of the container, ensures that the container can maintain structural integrity when being impacted by pressure or external force, and reduces the risk of leakage or rupture.

Examples
As shown in fig. 1 and 2, the present embodiment discloses an exemplary structure of a multi-film glass fiber reinforced plastic container, which has the characteristics of light weight, corrosion resistance and high strength.
Structurally, the container adopts a composite structure of the inner liner layer 1, the structural layer 2 and the outer protective layer 3, and improves the mechanical strength and corrosion resistance of the container in a mode of alternately combining a plurality of glass fiber layers 4 and polymer films 5.
Specifically, the inner liner 1 of the glass fiber reinforced plastic container is made of glass fiber reinforced plastic, has a thickness of 2-5 mm a, has a smooth surface and is corrosion-resistant, and provides the container with basic tightness and corrosion resistance.
In this embodiment, the structural layer 2 is a critical part of the container, and is composed of multiple glass fiber layers 4 alternating with polymer films 5. The glass fiber layer 4 is formed by solidifying E glass fiber fabric and epoxy resin, the fabric density is 200-400 g/m, the glass fiber diameter is controlled to be 10-15 micrometers, and the single-layer thickness is 2-5 mm. The high polymer film 5 adopts polytetrafluoroethylene film with the thickness of 0.02-0.05 mm, and has excellent chemical stability and anti-leakage capability. The final stacking sequence of the structural layers is: the total thickness of the glass fiber layer 4/polytetrafluoroethylene film/glass fiber layer 4 is 8-15 mm, so that the structural layer is ensured to have enough strength and durability.
In this embodiment, the outer protective layer 3 is an ultraviolet-resistant polyurethane or epoxy resin coating with a thickness of 0.3-1 mm, so as to effectively prevent the damage of the external environment to the structural layer.
In the manufacturing process, the E glass fiber fabric is cut first, and the glass fiber is impregnated with the mixed epoxy resin to be fully saturated. Meanwhile, the polytetrafluoroethylene film is cut according to the design size for standby. Then, the respective layers were laminated in this order of the glass fiber layer 4/polytetrafluoroethylene film/glass fiber layer 4, and bonded with epoxy resin. And placing the overlapped structural layers 2 into a mould, carrying out compression molding, and curing for 3-6 hours at the temperature of 80-120 ℃ to ensure full adhesion between the layers, thereby forming the integral composite structural layer.
After the structural layer 2 is cured, the inner side and the outer side of the structural layer are respectively coated with glass fiber reinforced plastic and ultraviolet-resistant polyurethane or epoxy resin coating so as to form a complete inner liner layer 1 and an outer protective layer 3. Finally, a multi-film glass fiber reinforced plastic container is formed.
It will be appreciated that when the glass reinforced plastic container of the present embodiment is subjected to an external impact such as a weight strike or an unexpected drop, an external force acts on the outer protective layer 3 first. The outer protective layer 3 is made of polyurethane or epoxy resin, has certain impact resistance and toughness, and can disperse part of impact force and lighten the stress of the structural layer. The outer protective layer 3 absorbs and disperses part of the impact force, reducing the direct influence on the structural layer 2. Under light impact, the outer protective layer 3 may be scratched or slightly broken, but the structural layer 2 remains intact, and the glass fiber reinforced plastic container can still be used normally. Under severe impact, a certain glass fiber layer 4 in the structural layer 2 may be broken, but the polymer film 5 can provide anti-leakage protection, so as to ensure that the internal medium cannot leak.
When a certain glass fiber layer 4 of the glass fiber reinforced plastic container is broken or damaged, the immediately adjacent polymer film 5 can act as an anti-seepage barrier, and other unbroken glass fiber layers 4 can continue to provide mechanical strength. The polymer film 5 (polytetrafluoroethylene film) has excellent chemical stability and anti-leakage performance, can prevent medium leakage at damaged parts, and simultaneously maintains the pressure and the tightness inside the glass fiber reinforced plastic container. The combination of multiple fiberglass layers 4 with polymeric film 5 provides redundancy protection, and even if a single fiberglass layer 4 breaks, the other layers provide strength and protection against leakage. The broken glass fiber layer 4 does not cause leakage of medium under the protection of the polymer film 5, but the overall strength is slightly lowered.
It should be understood that the working principle is based on the multi-layer protection design of combining the multi-layer glass fiber layer 4 and the polymer film 5, and the overall performances of light weight, high strength and corrosion resistance are realized through the toughness of the outer protection layer 3, the anti-leakage property of the polymer film 5 and the redundant strength of the multi-layer glass fiber layer 4.
Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the disclosure.
