Further, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic can be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Examples
Referring to fig. 1 and 2, this embodiment provides a nonmetallic low-temperature storage tank, which includes a tank body 100, wherein the interior of the tank body 100 is a multi-layer laminated structure, and sequentially includes, from outside to inside, an outer layer 101, a middle layer 102 and an inner layer 103, the outer layer 101 is a composite structural layer, the middle layer 102 is a heat insulation material layer, and the inner layer 103 is an inner liner of the tank body 100, that is, a polymer material airtight layer.
The outer layer 101 (composite material structural layer) in the low-temperature storage tank is equivalent to the outer shell of the traditional storage tank, the traditional steel shell is replaced by the high-strength composite material, higher strength can be provided, better service life and weather resistance are achieved, the middle layer 102 (heat preservation material layer) and the traditional heat preservation layer are not repeated in the same specific structure, heat transfer blocking is achieved, heat dissipation and diffusion are reduced, and the inner layer 103 (high-polymer material airtight layer) is insulated and gaps are reduced to prevent leakage of low-temperature liquid.
The preparation principle is as follows: firstly, pouring composite material liquid into a mould through a storage tank mould, after the outer layer 101 is formed, installing an insulating layer inside, and finally installing an airtight layer of a high polymer material.
The outer layer of the composite material provides basic structural strength and compression resistance, the heat transfer is blocked by the inner heat preservation layer to reduce heat dissipation and diffusion, the inner polymer airtight layer is used for insulation and reducing gaps to prevent leakage of low-temperature liquid, the metal inner liner is replaced by the polymer material to reduce expansion and contraction, and the welding process is not used in the manufacturing process of the nonmetallic material low-temperature storage tank, so that the composite material low-temperature storage tank is higher in quality and safer, fewer in gaps, the diffusion of small molecular gas is reduced by the way of improving the air tightness of the polymer material, sufficient strength is provided to realize pressure, the toughness of the polymer material is avoided expansion and contraction at low temperature, and the higher storage pressure and the lower gasification rate are realized.
Specifically, the composite material structural layer is composed of fiber winding resin, the tensile strength exceeding 1000mpa can be realized through a polymer post-curing process, the fiber winding resin is mainly prepared into a pressure vessel by adopting glass fiber winding and polymer compounding, and the polymer comprises the following components in percentage by weight:
during preparation, firstly, accurately weighing epoxy resin, curing agent, diluent, flame retardant and TETA through a metering scale, then, preparing a transparent container capable of sealing and vacuumizing, controlling the indoor temperature to be 15-20 ℃, pouring the weighed material into the container, stirring for 3 minutes, and mixing and forming after no bubble exists in the container.
In the prior art, a composite material high-pressure container for energy storage uses a fiber as a main reinforcing system and a high-rigidity matrix resin material to obtain a pressure-resistant and safe storage container, but most glass fibers are not selected due to relatively low strength and fatigue resistance when the storage container with higher pressure or lower temperature is manufactured; the composite material for the high-pressure container generally focuses on the adoption of high-strength high-rigidity matrix resin, and has the defects of lacking of toughness elements in design and practical material use and incapability of combining toughness under different temperatures and environments. The individual resin toughening scheme adopts a particle adding method, is not improved from a high molecular chain, and has limitation in toughness improvement.
Therefore, the pressure container in the device is made of fiber winding and polymer composite, the glass fiber is the same product with highest strength and modulus, the polymer matrix material has high flexibility and low temperature resistance besides high strength and rigidity, the fiber is uniformly and tightly wound, and the resin flows fully and infiltrates the fiber bundle; the fiber surface sizing layer contains affinity resin substances and reactive groups, can be compatible with the resin materials and can be subjected to molecular reaction crosslinking, so that the composite material has high strength in the aspects of whole and local.
The strength of the glass fiber-resin composite material reaches the level close to that of the carbon fiber composite material through the proposal of the design scheme of the fiber material, and the container structural material has low temperature resistance and crack resistance through introducing flexible components into the resin high molecular structure.
At present, the traditional low-temperature storage tank liner is mostly made of metal materials, and the liner (namely the inner layer 103) in the low-temperature storage tank is mainly made of high polymer materials, so that the extremely high low-temperature resistance, thermal expansion and contraction resistance and brittle fracture resistance of the pressure container liner can be realized, and the service performance advantage and the long-term safety coefficient of the liner material are ensured.
Further, the polymer material is prepared into the super-tough liner material by directly mixing the monomer, the prepolymer, the chain extender and the like in a metering manner, injecting the mixture into a container, and solidifying and polymerizing the mixture under rolling. According to different material proportion formulas, the pressure container is formed after rolling for 0.5-5 hours, and the composite material container and the inner container are integrated into a whole to be in compatible connection, so that the stress resistance, the temperature resistance and the comprehensive performance of the container and the inner container reach the best of the pressure container, the use success rate is greatly improved, and the service life of the product is greatly prolonged.
Still further, the high molecular material introduces a super-tough material system which takes a soft chain structure as a main continuous phase, has a hard segment structure which is closely arranged and is microscopically dispersed in a molecular structure, adopts a high-strength super-tough material which is flexibly, rigidly, strongly and tough optimized on the design of molecules and microstructures to replace polyethylene as an inner container material, uniformly and tightly winds fibers, and fully flows and infiltrates fiber bundles; the fiber surface sizing layer contains affinity resin substances and reactive groups, can be compatible with the resin materials and can be subjected to molecular reaction crosslinking, so that the composite material has high strength in the aspects of whole and local.
In the structure, the strength of the glass fiber-resin composite material reaches the level close to that of the carbon fiber composite material through the proposal of the design scheme of the fiber material, and the container structural material has low temperature resistance and crack resistance through introducing flexible components into the resin high molecular structure; by selecting ultra-strong rigid glass fibers, the strength modulus of the composite material exceeds the level of a conventional glass fiber composite material. The proportion of the fiber material in the shell is 30% -90%; the fiber surface is subjected to affinity infiltration with resin and chemical reaction crosslinking, so that the composite material achieves higher strength and rigidity, the reaction is carried out in a specific temperature environment, and a flexible chain segment is introduced through the design of a high molecular level, so that the high molecular and the composite material have higher flexibility.
The polyethylene inner container and the composite material container adopted in the market are different parts, are not bonded with each other, and can fall off and separate from each other when in thermal expansion and contraction.
