Description

Technical Field

[0001] This utility model relates to the field of silicone pads, specifically an antistatic silicone pad. Background Technology

[0002] In scenarios such as electronic component manufacturing, precision instrument operation, and laboratory testing, electrostatic interference or electrostatic discharge has become a key issue affecting product quality and equipment stability. Antistatic silicone pads, as basic consumables that combine electrostatic protection and surface protection functions, are widely used in various electrostatic sensitive environments.

[0003] Existing antistatic silicone pads mostly employ a single antistatic strategy. One type relies on surface-coated antistatic agents to dissipate charge, but these agents are easily lost with friction and cleaning, causing the antistatic performance to rapidly decline over time. Another type incorporates conductive fillers to build a conductive network, which offers more durable performance, but the amount of conductive filler added must be strictly controlled. Insufficient filler leads to low static dissipation efficiency and an inability to quickly conduct away accumulated charge, while excessive filler significantly reduces the elasticity and flexibility of the silicone pad, making it brittle and reducing the user experience. Therefore, we propose an antistatic silicone pad. Utility Model Content

[0018] Furthermore, the conductive mesh component includes conductive fiber 1 (6) and conductive fiber 2 (7). The silicone base layer 1 is filled with multiple sets of conductive fiber 1 (6). Each set of conductive fiber 1 (6) consists of multiple conductive fibers 1 (6) distributed equidistantly along a straight line. The multiple sets of conductive fibers 1 (6) within the silicone base layer 1 are parallel to each other. The silicone base layer 1 is also filled with multiple sets of conductive fiber 2 (7). Each set of conductive fiber 2 (7) consists of multiple conductive fibers 2 (7) distributed equidistantly along a straight line.

[0019] Furthermore, the hydrophilic moisturizing layer component includes a water-resistant silicone layer 2 and a hydrophilic filler 9. One side of the silicone base layer 1 is connected to the water-resistant silicone layer 2. The silicone base layer 1 and the water-resistant silicone layer 2 are integrally bonded by hot pressing. The side of the water-resistant silicone layer 2 facing away from the silicone base layer 1 is filled with the hydrophilic filler 9. The water-resistant silicone layer 2 is insoluble in water and inorganic acids, and has good water resistance and mechanical strength. When filled with the hydrophilic filler 9, it does not crack when exposed to water and can maintain the stability of the structure. At the same time, its porous structure and adsorption properties also help to combine with hydrophilic materials. The hydrophilic filler 9 is made of polyethylene glycol, which is solid at room temperature, easily soluble in water, and has strong hydrophilic groups such as ether bonds and hydroxyl groups that can form hydrogen bonds with water molecules. Moreover, the molecular chain is flexible and can be uniformly dispersed in the matrix, slowly releasing moisture absorption capacity.

[0020] Furthermore, the water-resistant silicone layer 2 has multiple evenly distributed grooves 8 on the side facing away from the silicone base layer 1. The hydrophilic filler 9 is filled in the grooves 8. The grooves 8 are used to fill the hydrophilic filler 9. The size and number of grooves 8 are provided without affecting the strength and toughness of the water-resistant silicone layer 2.

[0021] Furthermore, the side of the water-resistant silicone layer 2 with the groove 8 is opposite to the supporting silicone layer 3. The supporting silicone layer 3 covers the side of the hydrophilic filler 9 outside the groove 8. The supporting silicone layer 3 and the water-resistant silicone layer 2 are bonded together. The supporting silicone layer 3 is made of addition-curing silicone. When used as an outer supporting silicone layer, it can accurately replicate the shape and details of the mold and ensure the dimensional accuracy of the product.

[0022] Furthermore, the side of the supporting silicone layer 3 facing away from the hydrophilic filler 9 is provided with multiple uniformly distributed micropores 10. The micropores 10 are used to ensure the communication between the hydrophilic filler 9 and the outside world, to maintain humidity, and to eliminate static electricity.

[0023] Furthermore, the side of the supporting silicone layer 3 facing away from the water-resistant silicone layer 2 is connected to the self-cleaning layer 4. The supporting silicone layer 3 and the self-cleaning layer 4 are bonded together with a breathable adhesive. The self-cleaning layer 4 is made of fluorine-modified silicone, which retains the elasticity and aging resistance of silicone. The surface is treated with fluorine to reduce surface energy. The micron-sized air bubbles or fiber-reinforced pores in the silicone matrix prevent oil stains from penetrating and allow dust to be easily blown away by the wind. It can be repeatedly cleaned and has long-lasting non-stick properties, reducing the adhesion of dust and oil stains, avoiding static electricity generated by friction, and ensuring breathability.

[0024] Furthermore, the side of the silicone base layer 1 facing away from the water-resistant silicone layer 2 is connected to the self-cleaning layer 5. The self-cleaning layer 5 and the silicone base layer 1 are joined together by hot pressing. The self-cleaning layer 5 is made of fluorine-modified silicone.

[0025] Structural Description: Silicone base layer 1: Sheet-shaped elastomer structure, flexible in texture, with embedded conductive mesh components. As the core carrier of the overall structure, it provides the installation base for water-resistant silicone layer 2 and self-cleaning layer 5, while ensuring user comfort due to the elasticity of silicone. Water-resistant silicone layer 2: sheet-like porous structure with a smooth surface and uniformly distributed grooves 8 on one side. Relying on its water-resistant and porous properties, it provides a stable supporting matrix for the hydrophilic filler 9, preventing the filler from being lost or cracked when exposed to water, and ensuring the long-lasting moisturizing function. Supporting silicone layer 3: Sheet structure, one side is attached to water-resistant silicone layer 2, and the other side has multiple micropores 10. It is made of addition-cured silicone and plays a structural support role, accurately maintaining the overall shape. The micropores 10 form a water vapor exchange channel. Self-cleaning layer 4: Thin sheet elastic structure, the matrix contains micron-sized pores, the surface is fluorinated, and it is protected against oil and dust through low surface energy properties, reducing friction and static electricity. At the same time, the pores ensure breathability, and together with the micropores 10 supporting the silicone layer 3, water vapor can circulate. Self-cleaning layer 2 5: Thin sheet structure, tightly bonded to silicone base layer 1, also made of fluorine-modified silicone, with the same anti-fouling and self-cleaning function as self-cleaning layer 1 4, forming double-sided protection, further suppressing the generation of surface static electricity. Conductive Fiber 16: A fibrous strip structure with multiple sets of parallel and equidistantly distributed fibers, which are perpendicularly bonded to Conductive Fiber 27 to form a grid. The carbon fiber material ensures conductivity and is responsible for rapidly conducting electrostatic charges in the lateral area. Conductive fiber 2 7: A fibrous strip structure that is perpendicularly distributed to conductive fiber 1 6. As a longitudinal component of the conductive grid, it works in conjunction with conductive fiber 1 6 to construct a seamless conductive network, thereby achieving full-domain charge dispersion. Groove 8: A regular recessed structure formed on the surface of the water-resistant silicone layer 2. The number of grooves is uniform and the size is consistent. It is specifically used to fill the hydrophilic filler 9, which improves the filler loading and stability without damaging the toughness of the water-resistant silicone layer 2. Hydrophilic filler 9: Solid particles or block structures filled in groove 8, made of polyethylene glycol, adsorb and store water vapor through hydrogen bonds, and slowly release it when drying, providing a conductive water film for static electricity dissipation; Micropores 10: tiny through-holes that penetrate the supporting silicone layer 3, evenly distributed, opening up channels between the hydrophilic layer and the outside world, ensuring water vapor exchange between the hydrophilic filler 9 and the outside world, maintaining microenvironmental humidity, and assisting in the rapid dissipation of charge through the water film.

[0026] Working principle: The conductive mesh component embedded in the silicone base layer 1, with conductive fiber 6 and conductive fiber 7 vertically bonded together to form a regular mesh, avoids damaging the elasticity of the silicone while creating a seamless conductive network. When static electricity is generated on the surface of the silicone pad due to friction, the charge is quickly captured by the conductive mesh and conducted to the entire mesh system through the crisscrossing fibers, achieving rapid charge dispersion and preventing local static electricity accumulation and high potential formation from the source. The hydrophilic moisturizing layer structure maintains the microenvironment humidity through a closed-loop system of water storage, moisture release, and breathability, assisting in static electricity dissipation. The water-resistant silicone layer 2, with its porous structure and adsorption properties, provides a stable carrier for the hydrophilic filler 9. Its water resistance prevents structural cracking caused by water contact with the filler. The hydrophilic filler 9, polyethylene glycol, filled in the groove 8, utilizes the hydrogen bonding between ether bonds and hydroxyl groups. The micropores 10 supporting the silicone layer 3 continuously adsorb and store external moisture, which is then slowly released in a dry environment, forming an extremely thin conductive water film on the surface of the silicone pad. The ions in the water film can accelerate charge transfer, significantly reducing the impact of environmental humidity on antistatic performance. The self-cleaning layers on both sides reduce the source of static electricity through their low surface energy characteristics. Both self-cleaning layer 1 4 and self-cleaning layer 2 5 are made of fluorine-modified silicone. After fluorine treatment, the surface energy is significantly reduced, making it difficult for oil stains to penetrate. Dust is easily removed under the action of airflow, fundamentally reducing the static electricity caused by dust micro-friction and oil stain insulation layer. At the same time, the micron-level pores in the matrix of self-cleaning layer 1 4, together with the micropores 10 supporting the silicone layer 3 and the breathable adhesive, form a breathable channel, which not only ensures the exchange of moisture between the hydrophilic moisturizing layer and the outside environment, but also avoids charge retention caused by a closed environment, achieving a functional balance between self-cleaning and breathability.
