Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter material structure technology, and in particular to a composite material structure containing glass fiber cotton and polyester fiber. Background Technology
[0002] Air filters are essential devices for purifying air and improving air quality. They are widely used in household, industrial, and medical fields. The filter material is the core component of an air filter, and its performance directly affects the filter's filtration efficiency, resistance, and service life.
[0003] Traditional air filter materials typically use a single material, such as fiberglass or polyester, to create air filters with a single efficiency level. However, in practical applications, it is often necessary to use filters of different efficiency levels in series to meet diverse filtration needs.
[0004] Currently available air filter materials suffer from limitations in meeting diverse filtration efficiency requirements due to their singular efficiency and limited performance. Traditional filter materials are typically limited to single-efficiency filters, failing to satisfy diverse filtration needs. Furthermore, single-material filter materials have limitations in terms of capture efficiency, resistance, and strength, making it difficult to balance various performance indicators. For example, patent CN201920123456.7 discloses a glass fiber cotton air filter material, which has high capture efficiency but high resistance and can only be made into a single-efficiency filter, necessitating further improvements in filter materials.

[0020] The technical effects and advantages of this utility model are as follows:
[0021] This invention combines glass fiber cotton and polyester fiber cotton in a composite manner, forming a composite material with gradient filtration efficiency by compounding glass fiber cotton and polyester fiber in different proportions. This material can simultaneously meet the filtration needs of particles of different sizes. Glass fiber cotton has high capture efficiency, while polyester fiber has low resistance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides, for example Figure 1-3 The composite material structure shown includes glass fiber cotton and polyester fiber, comprising a glass fiber cotton body 1, a polyester fiber cotton body 2, and an adhesive layer 3. The glass fiber cotton body 1 can capture particles of different sizes. The polyester fiber cotton body 2 is disposed below the glass fiber cotton body 1 and is used to improve the strength and durability of the composite material. The adhesive layer 3 is disposed between the glass fiber cotton body 1 and the polyester fiber cotton body 2. The adhesive layer 3 is arranged in a mesh structure and is used to fix the glass fiber cotton body 1 and the polyester fiber cotton body 2.
[0028] The glass fiber cotton body 1 includes a glass fiber cotton layer 11 and a flame retardant layer 12. The multiple glass fiber cotton layers 11 are stacked together. The flame retardant layer 12 is disposed on the outer wall of the multiple glass fiber cotton layers 11. The multiple glass fiber cotton layers 11 are dried to form a fluffy structure. The flame retardant layer 12 is bonded and fixed to the adhesive layer 3.
[0029] Specifically, the glass fiber cotton layer 11 includes glass filaments 1101 and an adhesive layer 1102. Multiple glass filaments 1101 are arranged adjacent to each other, and the glass filaments 1101 are fine filaments. The adhesive layer 1102 is used to bond and fix the multiple glass filaments 1101.
[0030] Further, the manufacturing method of the glass fiber cotton body 1 is as follows: after melting glass, the molten glass is blown into fine filaments through a nozzle under pressure using air flow through a micropore. The fine filaments are glass filaments 1101. Then, an adhesive is added for bonding. The adhesive bonding the glass filaments 1101 forms an adhesive layer 1102, which is bonded to form a glass fiber cotton layer 11. After multiple layers of glass fiber cotton layers 11 are stacked, the stacked glass fiber cotton layers 11 are placed in a drying equipment for drying. The multiple layers of glass fiber cotton layers 11 are made into a fluffy state, so that the upper and lower surfaces and sides of the stacked multiple layers of glass fiber cotton layers 11 form a smooth skin. Finally, a flame retardant is added to its surface, and the added flame retardant forms a flame retardant layer 12, forming the glass fiber cotton body 1.
[0031] In addition, the polyester fiber cotton body 2 includes multiple layers of polyester fiber cotton 21, each layer including polyester fiber warp 2101 and polyester fiber weft 2102, which are woven together in a warp and weft pattern.
[0032] Further, the manufacturing method of the polyester fiber cotton body 2 is as follows: after mixing the primary polyester fibers, the mixture is conveyed to the opening position by a conveyor belt to loosen and open the fibers, so that all the curled fibers are unrolled. The fibers are combed to form polyester fiber warp 2101 and polyester fiber weft 2102. Multiple polyester fiber warp 2101 and multiple polyester fiber weft 2102 are laid into a warp and weft mesh to form a polyester fiber cotton layer 21. The polyester fiber cotton layer 21 laid into a mesh structure is shaped to a specified width and thickness according to parameters. Then, the polyester fiber cotton layer 21 laid to a specified width and thickness is placed in an oven. After drying and curing, a uniform surface coating is formed, and the polyester fiber cotton body 2 is formed.
[0033] After cutting and finishing processes, the glass fiber cotton body 1 and polyester fiber cotton body 2 are finally made into the required semi-finished products. Adhesive is then applied to the contact surfaces of the polyester fiber cotton body 2 as needed, and then it is covered with glass fiber. The adhesive forms an adhesive layer 3 between the glass fiber cotton body 1 and the polyester fiber cotton body 2, which bonds and fixes them together. The bonded glass fiber cotton body 1 and polyester fiber cotton body 2 are then laminated under heat and high pressure to form the final composite material structure containing glass fiber cotton and polyester fiber. By laminating glass fiber cotton body 1 and polyester fiber cotton body 2 in different proportions, a composite material with gradient filtration efficiency is formed, which can simultaneously meet the filtration requirements of particles of different sizes. It features high capture efficiency and low resistance. Polyester fiber has excellent mechanical properties, which can improve the strength and durability of the composite material and extend the service life of the filter. This composite material can cover two efficiency levels, G4 and F9, and is particularly suitable for large-scale replacement of primary plate filters and sub-high efficiency V-type filters, providing equivalent filtration effect but with significantly reduced costs.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
