Detailed ways

The following describes the implementation of the present invention through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

It should be noted that the illustrations provided in this embodiment only illustrate the basic idea of the present invention in a schematic manner. The figures only show the components related to the present invention instead of the number, shape, and shape of the components in actual implementation. For the size drawing, the type, quantity, and proportion of each component can be changed at will during actual implementation, and the component layout type may also be more complicated.

As shown in FIG. 1, this embodiment proposes a method for manufacturing an insulating core material, including:

S1: Provide a core material;

S2: Dispersing treatment is performed to disperse the core material to obtain a loose core material;

S3: Perform a layup step to lay up the loose core material to obtain a laminated core material;

S4: Perform a needling step to perform acupuncture treatment on the stacked core material to obtain a firm core material;

S5: Perform a hot pressing step to perform hot pressing on the firm core material to obtain a molded core material;

S6: Perform a drying step to perform drying treatment on the shaped core material to obtain a dried core material;

In step S1, the core material is, for example, a wet-process integrated core material or a thermosetting integrated core material. The wet-process integrated core material is, for example, a centrifugal cotton, flame cotton, and mineral wool, mixed and stirred in proportion, and subjected to a wet molding process. Specifically, the wet-process integrated core material includes the following raw materials by weight: centrifugal cotton 60%-100%, flame cotton 10%-20%, mineral wool 10%-50%. The thermosetting integrated core material is, for example, wet-process core material or dry-process glass wool under high temperature and high pressure conditions, and solidified within a certain period of time. Specifically, the thermosetting integrated core material is made of wet-process core material or dry-process glass wool. The temperature is 480～550℃, the pressure ratio is 3～7 times, and the curing time is 2～10min. In this embodiment, the core material can be mixed with multiple raw materials in a certain ratio or use one kind of raw material. In this embodiment, the glass fiber material is used as the core material for description.

In step S2, the core material is first placed on multiple electronic scales in sequence, and the weighing ranges on the multiple electronic scales are different. For example, the weighing range of the first electronic scale is 1kg, and the weighing range of the second electronic scale is 2kg, then spread the core material on the electronic scale on the mixed curtain according to the preset procedure, and then the core material is conveyed to the opening machine through the inclined curtain and conveyor belt, so as to perform rough opening and fine opening of the core material loose. In this embodiment, the diagonal curtain uses, for example, an anti-static curtain as the base fabric, and the working frequency of the diagonal curtain is, for example, 1-49 Hz, so as to precisely control the feeding speed. In this embodiment, multiple licker rollers can be used for rough opening, for example, multiple licker rollers are arranged in sequence, and the speed of the front licker roller is lower than the speed of the next licker roller, and the speed ratio of the multiple licker rollers is, for example, 1: 59. The frequency of multiple licker rollers is 1-49HZ, and the frequency of multiple licker rollers is allowed to be adjusted. In this embodiment, the operating frequency of the opener can be, for example, 10-45HZ. Therefore, the frequency of the opener can be adjusted so that the opener can coarsely open and finely open the core material.

In step S3, the core material after opening is carded. First, the core material is sequentially passed through the feeding roller, and the four rollers enter the chest cylinder. A plurality of work rollers and stripping rollers are arranged on the chest cylinder. The core material is carded by multiple work rolls and stripping rolls, and then the core material passes through the transfer roll and the main cylinder. The main cylinder is provided with multiple work rolls and opening rollers. The multiple work rolls and opening rollers on the main cylinder re-open the core material. The carded core material is transformed from a messy state to a stripping roller state. In this embodiment, the metal material in the core material can be monitored when the core material passes through the four rollers. If the core material contains metal materials, the four rollers will return to the core material. In this embodiment, the rotational speed of the chest cylinder is, for example, 0-500 r/min, and the linear speed of the chest cylinder is 0-1000 m/min. The rotation speed of the main cylinder is, for example, 0-500r/min, and the linear speed of the chest cylinder is 0-1500m/min. The rotational speed of the upper and lower doffer is, for example, 0-100 r/min, and the linear speed of the upper and lower doffer is, for example, 0-200 m/min. In this embodiment, the core material after passing through the carding machine becomes a single fiber state, the glass fiber is straightened, and impurities and extremely fine fibers are removed. Because glass fiber and other organic fibers have different properties, for example, the relative density of glass fiber is large, which is about twice that of synthetic fiber; glass fiber is round rod-shaped, smooth surface, non-crimping, and the cohesive force of fiber and fiber is small. ; Glass fiber is a brittle material, not resistant to bending and wear. Therefore, the carding machine can be comprehensively selected and improved from the carding machine and the carding machine in the selection of the carding machine. In some embodiments, suitable card clothing can be selected according to the characteristics of the glass fiber, such as using horizontal-grained card clothing to increase the card clothing’s gripping of the glass fiber, increase the friction, or adjust the card clothing tooth spacing. Improve the carding result, or control the speed of the licker roller, cylinder and transfer roller, reduce the damage to the fiber, improve the carding ability, or because the fiber entering the carding machine contains some impurities, the glass fiber has a large specificity and is smooth without embracing As a result, a large number of short glass fibers fall into the belly of the machine, causing waste. The position of the dust removal knife, the installation angle and the distance from the licker roller can be adjusted to reduce the glass fiber falling into the belly of the machine to a minimum. , Or because of the brittleness of glass fiber, the size of the gap can be adjusted to avoid excessive combing to damage and break the glass fiber, resulting in a large amount of glass fiber crushing.

In step S3, the core material after the carding machine forms a laminated core material under the action of the netting machine. In this embodiment, a parallel netting machine or a cross-laying machine can be used, for example, a cross-laying machine is used to The glass fiber mesh (core material) is laminated (that is, a single glass fiber mesh layer is folded at 90 degrees and reciprocally laminated) to form a glass fiber laminate (laminated core material) with a basic ^{weight of 1000-15000 g/m 2.} In other embodiments, if a 10mm thick insulation board is to be made, the core material of the glass fiber laminate has a weight of 2500g/m ² , and the cross-laid machine will stack 32-50 layers of glass fiber nets. If other thicknesses are required For the insulation board, the number of layers of the glass fiber mesh can be adjusted according to the needs.

In some embodiments, since the glass fiber is rubbed with the constantly moving machinery in the equipment such as opening, carding, and netting, it is easy to accumulate charges on the surface of the fiber, causing the fiber to repel each other and the fiber and the machine. Attract, so that the glass fiber gathers in clusters in the cylinder of the carding machine, the netting box or the corner of the netting machine, etc. Therefore, the glass fiber will be poorly combed and the uniformity of the web will be poor. In order to overcome the influence of static electricity, the following measures can be adopted: install static elimination devices on the opener, carding machine and laminator, or spray antistatic agent on the glass fiber before opening, or add the glass fiber in the sizing agent in the production Other measures such as antistatic agent.

As shown in Figure 2, in step S4, the laminated core material 12 is transported to the needle punching device 10, the core material transport volume can reach 300-4000 g/m ² , the laminated core material 12 is processed by the needle punching device 10 Acupuncture treatment. In this embodiment, the needle punching device 10 includes a net feeding mechanism, which includes two pressing rollers 11, the two pressing rollers 11 form a shape with a large opening and a small outlet, and a laminated core material 12 It enters from the opening and exits from the outlet, thereby entering between the stripping plate 16 and the supporting plate 17. The acupuncture device 10 includes a needling mechanism, and the acupuncture device includes an active mechanism 13, a needle plate 14, a needle 15, a stripping plate 16 and a supporting plate 17. Among them, the needle 15 is located on one side of the needle plate 14, the active mechanism 13 is connected to the other side of the needle plate 14, the stripping plate 16 is located above the supporting plate 17, the needle plate 14 is located above the stripping plate 16, and the puncturing needle 15 is connected to the stripping plate. The meshes of the stencil 16 correspond to each other. When the laminated core material 12 enters the stripping plate 16 and the supporting plate 17, the active mechanism 13 drives the needle plate 14 to reciprocate up and down, and the puncture needle 15 needle punches the laminated core material 12 through the stripping plate 16 to improve the stacking The stability and firmness of the core material 12. When the puncture needle 15 leaves the laminated core material 12, the stripping plate 16 functions to peel off the core material and the puncture needle 15. The needle punching device 10 includes an output mechanism that includes two traction rollers 18. While the laminated core material 12 is being needled, the output mechanism will take out the laminated core material 12 and draw the line of the roller 18 The speed is matched with the speed of the pressing roller 11, and the speed of the traction roller 18 is too fast, which will affect the quality of the product, and even break the needle. In this embodiment, when the barbs on the puncture needle 15 pass through the fiber web (laminated core material 12), the surface and partial inner fibers of the fiber web are forced to penetrate into the interior of the fiber web, and the puncture needle 15 is removed from the laminated core. One side of the material pierces the other side, but does not penetrate the other side, so fiber bundles cannot be formed in the direction perpendicular to the core material, thereby improving the thermal insulation performance of the core material. In this embodiment, when the lancet 15 pierces from one side of the core material to the other side, there is a certain distance between the end of the lancet 15 and the other surface of the core material, for example, 1 mm, 2 mm or 2.5 mm. When the felting needle 15 exits the fiber web, the pierced fiber bundles detach from the barbs and stay in the fiber web. As a result, multiple fiber bundles entangle the fiber web and cannot restore the original fluffy state, thus enhancing the firmness and firmness of the fiber web. stability.

As shown in FIG. 3, this embodiment provides a schematic diagram of a needle punching treatment on the upper and lower sides, that is, the laminated core material is subjected to the needle punching treatment on the upper and lower sides. As shown in Figure 3, needle plates are provided on both sides of the laminated core material 101, that is, the first needle plate 103 is provided on the first surface of the laminated core material 101, and on the second surface of the laminated core material 101 A second needle plate 104 is provided, and needle net plates 102 are provided on both the first surface and the second surface of the laminated core material 101. During the needling treatment, the puncture needle 105 on the first needle plate 103 pierces from the first surface to the second surface, and the puncture needle 105 on the first needle plate 103 does not penetrate the second surface, that is, on the first needle plate 103 There is a certain distance between the end of the puncture needle 105 and the second surface. For example, the distance between the end of the puncture needle 105 on the first needle board 103 and the second surface is, for example, 0.5mm, 1mm, 1.2mm or 1.5mm. . At the same time during the needling treatment, the puncture needle 106 on the second needle plate 104 pierces the first surface from the second surface, and the puncture needle 105 on the second needle plate 104 does not penetrate the first surface, that is, the first needle plate 103 There is a certain distance between the end of the lancet 106 and the first surface. For example, the distance between the end of the lancet 106 on the second needle plate 104 and the first surface is, for example, 0.5 mm, 1 mm, 1.2 mm, or 1.5. mm. Since the puncture needle 105 on the first needle board 103 does not penetrate the second surface of the laminated core material 101, and the puncture needle 106 on the second needle board 104 does not penetrate the first surface of the laminated core material 101, it cannot be positioned vertically. The fiber bundles are formed in the direction of the laminated core material 101, thereby improving the thermal insulation effect of the core material. During the needling treatment, the puncture needles 105 on the first needle plate 103 and the puncture needles 106 on the second needle plate 104 are staggered to prevent collisions. In some embodiments, the first needle plate 103 and the second needle plate 104 can work simultaneously or separately.

In this embodiment, the core material is needled on both sides to form a porous structure on the core material. At the same time, since the needle punching does not penetrate all the core material, fiber bundles cannot be formed on the surface perpendicular to the core material. Therefore, it has a better heat preservation effect.

In step S5, the needle punched core material is sent into a hot press for hot pressing. The laminated core material first passes through a preheating stage, which can remove volatiles and melt some low-melting polyester fibers Bonding glass fibers to form a core material product with better strength. The preheating temperature is 180-200°C. After the preheating stage, the core material enters a pair of hot rolling mills. The hot rolling mills are heated to 500-800℃ by electric heating or oiling. The rotation speed of the hot rolling mills is 1-3m/min, so that the surface of the laminated core materials is pressed. The surface is smooth and flat. Among them, the distance between the hot rolling mills can be adjusted according to the thickness of the formed core material, and the thickness of the formed core material is 10-15 mm. The molded core material formed by hot pressing can be automatically cut according to the shape and size requirements.
