Description

Technical Field

[0001] This invention relates to the field of humidity management materials technology, specifically to a multi-component synergistic precision humidity control composite material, its preparation method, and its application. Background Technology

[0002] Existing humidity management materials often suffer from insufficient humidity control precision, slow moisture absorption and release response, and performance degradation in extreme environments. Traditional silica gel desiccants can only absorb moisture in one direction and cannot achieve bidirectional humidity regulation. While some polymeric moisture-absorbing materials possess a certain capacity for moisture absorption and release, their moisture absorption capacity is difficult to reach 100% of their weight in high-humidity and high-temperature environments (45℃ / 95%RH), and their moisture release efficiency is low at 45℃ / 60%RH, failing to meet the requirements for high-precision humidity management. Furthermore, the preparation processes of existing materials are mostly simple blending processes, resulting in loose internal structures and poor synergy between components, leading to poor material cycle stability and short service life. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-component synergistic precision humidity control composite material, its preparation method, and its application, which solves the above-mentioned problems. This multi-component synergistic composite material can accurately absorb and release moisture within a specific humidity range, has excellent moisture absorption capacity in high humidity and high temperature environments, and high moisture release efficiency in high temperature and medium humidity environments. At the same time, the invention provides a preparation method and humidity control components for this material to meet the needs of high-precision humidity management.

[0004] Ensuring long-term environmental reliability: The entire system is halogen-free, with a total halogen (Cl+Br) content of ≤500ppm, meeting RoHS requirements; after aging at 85℃ / 85%RH for 1000h, it does not corrode copper or aluminum substrates, and its long-term performance retention rate is ≥85%, with a lifespan of more than 6 years.

[0005] Specifically, this involves a multi-component synergistic composite material that can absorb moisture when the relative humidity is ≥60%RH and release moisture when the relative humidity is <60%RH. The preparation method of the composite material and the humidity control components containing the composite material are suitable for enclosed spaces where precise humidity control is required, such as cavity humidity control and anti-condensation applications for vehicle-mounted lidar, optical camera modules, 5G / 6G radio frequency modules, medical sensing equipment and aerospace precision instruments, as well as electronic equipment cabinets, medicine storage boxes, food preservation packaging, archives and cultural relics warehouses and other scenarios.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-component synergistic precision humidity control composite material, the composite material composition by weight is as follows:

[0008] Main component one: 25-50 parts of polyacrylate resin or nitrile rubber.

[0009] Main component two: one or any combination of the following: superabsorbent polymer, sodium polyacrylate, diatomaceous earth, sodium formate, potassium formate, lithium saponite, hyaluronic acid, sodium hyaluronate, sodium polyglutamate, chitosan-based humectant, and calcium formate, 40-65 parts.

[0010] Flame retardant: 2-8 parts

[0011] Stearic acid: 1-3 parts

[0012] Dye: 0.1-1 part

[0013] Silicon powder: 2-6 parts

[0014] Titanium dioxide: 1-4 parts,

[0015] Vulcanizing agent system: 1-4 parts,

[0016] Alcohol-based additives and / or plasticizers DOA: 2-8 parts.

[0017] Furthermore, the use of polyacrylate resins and nitrile rubber in a weight ratio of 3:1 to 2:1 provides both good flexibility and hydrophilicity, offering a stable moisture-absorbing carrier structure for the material.

[0018] Furthermore, when multiple moisture-absorbing components are used, such as superabsorbent polymer or sodium polyacrylate, diatomaceous earth, sodium formate, and sodium hyaluronate salt, used simultaneously in a weight ratio of 5:2:1:1, they can rapidly swell and shrink when humidity changes, achieving efficient adsorption and release of moisture.

[0019] Furthermore, the alcohol-based additives are one or any combination of glycerol, propylene glycol, and polyethylene glycol, which can improve the hydrophilicity of the material, accelerate the diffusion and transport of moisture, and inhibit the aging of the material under high temperature conditions.

[0020] Furthermore, the flame retardant is any one of aluminum hydroxide, magnesium hydroxide, or halogen-free flame retardant, which can release moisture when the material burns, thus playing a role in flame retardancy and smoke suppression, while having minimal impact on the moisture absorption and release properties of the material.

[0021] Furthermore, the vulcanizing agent system consists of one or more of the following: sulfur vulcanizing agent, amine vulcanizing agent, and trithiocyanate vulcanizing agent, accelerator M, and accelerator D, with a weight ratio of 1:0.5:0.3. This system is used to achieve cross-linking vulcanization of polyacrylate resin or polyacrylate-nitrile rubber mixture, thereby improving the mechanical strength and stability of the material.

[0022] Furthermore, the plasticizer DOA is dioctyl phthalate, which can improve the flexibility and processing fluidity of the material, while having no negative impact on the material's moisture absorption and release properties.

[0023] This invention also provides the following technical solutions:

[0024] A method for preparing a multi-component synergistic precision humidity-controlled composite material includes the following two schemes:

[0025] Option 1 steps: Multi-stage mixing, addition of glycerol or DOA, compound open milling, segmented vulcanization, die cutting and forming.

[0027] Place the main component two, dye, and vulcanizing agent into the internal mixer two and mix them at 40-120℃ for 6-10 minutes to obtain the moisture-absorbing rubber compound.

[0028] S2, Glycerol additives or DOA addition: Add alcohol-based additives and / or plasticizer DOA to the elastomer base compound, and continue to mix in the internal mixer for 5-10 minutes to make the additives evenly dispersed in the elastomer base;

[0030] S4. Segmented vulcanization: Place the composite rubber compound into a vulcanization mold and pre-vulcanize it for 1-3 minutes at 100-170℃ and 6-15MPa pressure to build a stable cross-linked network structure.

[0031] S5. Die-cutting: After vulcanization, the material is taken out and die-cut according to requirements, and then installed.

[0032] Option Two steps: Multi-stage mixing, addition of glycerol or DOA, compound open milling, and mold vulcanization molding.

[0033] S1. Multi-stage mixing: Add main component one, flame retardant, stearic acid, silica powder, titanium dioxide, main component two, dye, vulcanizing agent, glycerol additive or DOA into internal mixer one, and mix at 40-100℃ for 8-15 minutes to obtain elastomer base rubber.

[0034] S2, Compound Mixing: Transfer the two rubber compounds to a mixing mill, control the roller temperature at 0-40℃, and mix for 5-12 minutes to the designed thickness to achieve uniform compounding of the elastomer and the hygroscopic component, forming a compound rubber compound;

[0035] S3. Mold vulcanization: Place the composite rubber compound into a vulcanization mold and pre-vulcanize it for 1-3 minutes at 120-180℃ and 10-45MPa pressure to build a stable cross-linked network structure finished product, and then install it.

[0036] This invention also provides the following technical solutions:

[0037] Application of a multi-component synergistic precision humidity control composite material, which is used in humidity control components.

[0038] The humidity control component has at least one humidity control unit made of a multi-component synergistic precision humidity control composite material inside its housing. The housing has micropores that allow water vapor to pass through. The corresponding number and specifications of humidity control units can be calculated and placed according to the volume of the sealed space, the initial humidity and the target humidity.

[0039] The beneficial effects of this invention are as follows:

[0040] Precise humidity control: The composite material of this invention can activate the moisture absorption mode when the relative humidity is ≥60%RH and switch to the moisture release mode when the relative humidity is <60%RH, precisely maintaining the ambient humidity within the target range;

[0041] Excellent moisture absorption and release performance: Under extreme high humidity and high temperature environment of 45℃ / 95%RH / 24H, it can absorb more than 100% of its own weight of water; under the conditions of 45℃ / 60%RH / 24H, it can release more than 50% of the adsorbed water, meeting the humidity management needs of high humidity environment.

[0042] Stable performance: Through multi-stage mixing, compound open milling and segmented vulcanization preparation process, the components form a stable synergistic structure, and the material has excellent cycle stability. After 1000 cycles of moisture absorption and desorption, the moisture absorption capacity retention rate can still reach more than 90%.

[0043] Customized production: We can produce products in different colors and cut into different shapes / sizes according to customer needs to suit a variety of application scenarios;

[0044] Performance optimization: After adding glycerol or DOA, the hydrophilicity and flexibility of the material are further improved, the moisture absorption and release response is accelerated, and the high temperature aging resistance of the material is improved.
