Description

Technical Field

[0001] This application relates to the technical field of ABS material processing, and particularly relates to an ABS material, a preparation method thereof, and an application thereof. Background Art

[0002] With the development of the economy, refrigerators, as common household appliances, have entered thousands of households. In order to achieve a better fresh-keeping effect, an automatic humidification function is adopted in the refrigerator. Therefore, a water box for realizing the automatic humidification function is added to the refrigerator. Currently, the water used by people is all tap water that has been purified. However, due to the long-term use of water pipes and the disinfection process of tap water, impurities such as rust, sand, bacteria, germs, and residual chlorine appear in the tap water. These impurities may be harmful to physical health, so the water needs to be purified. Currently, there have been many related studies on water purification treatment. A common method is to use a filter element equipped with calcium-magnesium water purification filler to pressurize and purify the water to remove impurities in the water.

[0003] However, since the refrigeration operation of the refrigerator will cause the temperature in the compressor compartment of the refrigerator to be too high, it is possible to cause problems such as aging of the outer shell of the filter element, deteriorating the pressure-bearing capacity of the outer shell of the filter element, and cracking of the outer shell during the pressure purification process.

[0004] In addition, as the number of uses of the filter element increases, harmful substances in the filler continue to deposit, resulting in a significant reduction in the purification effect. Therefore, it needs to be replaced regularly. However, the existing calcium-magnesium water purification filter element technology cannot judge the current usage situation of the water purification filter element, and can only perform regeneration or replacement according to the user's usage time. In the case where the user's water consumption and local water quality are uncertain, the guidance time is not accurate, which may cause the product to fail and affect the user's use, or result in waste of resources.

[0005] In summary, how to improve the heat resistance and pressure resistance of the calcium-magnesium water purification filter element and accurately control its replacement time is an urgent problem to be solved. Summary of the Invention

[0036] To make the objectives, implementation methods, and advantages of this application clearer, the following will clearly and completely describe the exemplary implementation methods of this application with reference to the accompanying drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0037] It should be noted that the brief description of the terms in this application is only for the convenience of understanding the subsequent described implementation methods, rather than intending to limit the implementation methods of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0038] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not be exclusive of inclusion. For example, a product or device that includes a series of components does not necessarily have to be limited to those components clearly listed, but may include other components that are not clearly listed or are inherent to these products or devices.

[0039] In a first aspect, an embodiment of this application provides an ABS material. Among them, the raw materials include, by mass percentage: 77.5 - 85% of ABS resin, 10 - 15% of heat-resistant and pressure-resistant regulator, 3 - 6% of transparent nucleating agent, 0.2 - 1% of high-temperature toughening agent, and 0.1 - 0.5% of lubricant; among them, the ABS resin is a butadiene-acrylonitrile-styrene copolymer.

[0040] The number-average molecular weight of the ABS resin in this application is 60,000 - 150,000. Among them, butadiene, acrylonitrile, and styrene are copolymerized, and the stereostructure of butadiene is an irregular long-chain structure.

[0041] The heat-resistant and pressure-resistant regulator in this application is a substance that can improve the high-temperature resistance and pressure resistance of the ABS material. The specific type of the heat-resistant and pressure-resistant regulator in this application is not limited. For example, nylon 6 can be selected.

[0042] The transparent nucleating agent in this application refers to a processing modification aid that is used to change the crystallinity of an incompletely crystalline polymer resin, thereby accelerating its crystallization rate. It can promote resin crystallization by providing crystal nuclei, making the structure of the crystal grains finer, thereby improving the transparency and mechanical properties of the ABS material. The specific type of the transparent nucleating agent in this application is not limited. For example, styrene-acrylate copolymer, butadiene, methacrylate, and sorbitol can be selected.

[0043] The high-temperature toughening agent in this application refers to a substance that can increase the flexibility of the ABS material at high temperatures. The specific type of the high-temperature toughening agent in this application is not limited. For example, acrylate rubber, polycarbonate, nylon 6 can be selected, and nylon 6 is preferred.

[0044] The lubricant in this application refers to the lubricating medium used to lubricate and reduce frictional resistance during the preparation of ABS materials. The selection of the lubricant in this application is not limited. For example, polyethylene wax oxide, ethylene bisstearamide, high melting point paraffin wax, PE wax, etc. can be selected, and polyethylene wax oxide is preferred.

[0045] By selecting the above raw materials and controlling the proportions of each component, this application can prepare ABS materials with excellent heat resistance, pressure resistance, and light transmittance. The inventor analyzed this principle and believes that the reason may be that the ABS resin has high hardness, toughness, and wear resistance, and the addition of heat and pressure resistance regulators, transparent nucleating agents, and high-temperature toughening agents can adjust the intermolecular forces and surface polarity of the ABS resin, and the contents of each component match each other, enabling the prepared ABS materials to achieve high heat resistance, high pressure resistance, and high light transmittance. The softening temperature of the ABS material prepared in this application is above 90 °C, and the pressure resistance can reach 1-4 kg / cm 2 , and the light transmittance is 80-90%.

[0046] In some embodiments of this application, the heat and pressure resistance regulator includes 10-25% of nylon 6 and 75-90% of styrene-acrylonitrile-butadiene rubber. To further improve the heat resistance and pressure resistance of ABS, the heat and pressure resistance regulator in this application is selected to include 10-25% of nylon 6 and 75-90% of styrene-acrylonitrile-butadiene rubber, wherein the styrene-acrylonitrile-butadiene rubber is prepared by replacing 40-50 wt% of butadiene in the ABS resin with butadiene rubber. The number average molecular weight of the styrene-acrylonitrile-butadiene rubber is 50,000-160,000, and the three-dimensional structure of butadiene is an irregular long-chain structure. When the above heat and pressure resistance regulator is selected, nylon 6 and styrene-acrylonitrile-butadiene rubber can change the structure of the ABS material, thereby changing the elasticity of the molecules moving intensively at high temperatures, and further increasing the heat resistance and pressure resistance of the ABS material.

[0047] In some embodiments of the present application, the transparent nucleating agent includes styrene-acrylate copolymer, butadiene, methacrylate, and sorbitol, and the mass ratio of styrene-acrylate copolymer, butadiene, methacrylate, and sorbitol is 1:3:2:0.5. Among them, the number-average molecular weight of the styrene-acrylate copolymer is 40,000-160,000, and the acrylate includes at least one of ethyl acrylate, methyl 2-methylacrylate, and ethyl 2-methylacrylate, etc., and the styrene and acrylate are copolymerized. When selecting styrene-acrylate copolymer, butadiene, methacrylate, and sorbitol and using them as the transparent nucleating agent according to a suitable mass ratio, during the preparation process of the ABS material, the transparent nucleating agent can reduce the crystallinity of the ABS material and promote the refinement of the grain size in the ABS material, so that the prepared ABS material has a higher light transmittance.

[0048] In some embodiments of the present application, the ABS material is obtained by a preparation method including the following process:

[0049] After mixing the ABS resin, heat-resistant and pressure-resistant regulator, transparent nucleating agent, high-temperature toughening agent, and lubricant, melt them and then perform granulation treatment to obtain the ABS material.

[0050] Specifically, mix the ABS resin, heat-resistant and pressure-resistant regulator, transparent nucleating agent, high-temperature toughening agent, and lubricant in an extruder, heat until all substances are melted, and then perform granulation treatment to obtain the ABS material, where the granulation treatment includes steps of water cooling, pelletizing, sieving, and drying.

[0051] The method for preparing the ABS material has a simple process, is beneficial to reducing the preparation cost of the ABS material, and the prepared ABS material has excellent heat-resistant and pressure-resistant properties and high light transmittance.

[0052] In the second aspect, the present application provides a method for preparing an ABS material, which includes: after mixing the ABS resin, chemical regulator, transparent nucleating agent, high-temperature toughening agent, and lubricant, melt them and then perform granulation treatment to obtain the ABS material.

[0053] In the method for preparing the ABS material of the present application, the melting temperature is 200-235°C. When the raw materials are melted at 200-235°C to prepare the ABS material, each raw material can be completely melted and can be fully mixed, so that the intermolecular force and surface polarity in the ABS resin are properly adjusted, thereby enabling the ABS material to achieve more excellent heat resistance, pressure resistance, and light transmittance.

[0054] In the third aspect, the present application provides a housing, which is made of the aforementioned ABS material or the ABS material obtained by the aforementioned preparation method.

[0055] In this application, the ABS material is added into the hopper of the injection machine and heated until it is in a molten state. Under the push of the screw or piston of the injection machine, it enters the mold cavity for preparing the housing through the nozzle and the gating system of the mold, and hardens and takes shape in the mold cavity to obtain the housing.

[0056] The housing of this application has a cavity, and the shape and size of the housing are not limited and can be selected according to the actual situation. Considering the pressure-bearing performance and water purification performance, the shape of the housing is preferably cylindrical. The material of the housing of this application is the ABS material prepared by the first aspect or the second aspect. The housing prepared by the ABS material has high heat resistance, high pressure resistance and excellent light transmittance.

[0057] This application does not limit the specific application scenarios of the housing. As long as there is a need for a housing with a high heat resistance, high pressure resistance and excellent light transmittance for accommodating purposes, the housing of this application can be used.

[0058] In a specific embodiment, the housing of this application is the housing of a filter element, and the cavity of the housing is used to accommodate the filter packing. Further, the filter element is used in a refrigerator to filter water to provide purified water for the automatic humidifying water box of the refrigerator. Figure 1 is a schematic structural diagram of the housing used in this application in a refrigerator, as Figure 1 shown, the housing may include an outer filter element barrel and a mounting base. The mounting base is connected to the outer filter element barrel, and the cavity of the outer filter element barrel communicates with the cavity of the mounting base. The filter packing is filled in the cavity of the outer filter element barrel. The inlet and outlet of the housing are both arranged on the mounting base. The water flow of the water supply member enters the cavity of the mounting base through the inlet and enters the cavity of the outer filter element barrel, contacts the filter packing to complete the filtration. The filtered water flow flows out through the outlet of the mounting base and flows to the humidifying member.

[0059] In the fourth aspect, this application provides a filter element, which includes the aforementioned housing and the filter packing filled in the cavity of the housing.

[0060] In this application, the filter element is prepared by filling the filter packing in the cavity of the aforementioned housing. Applying this filter element to a refrigerator can filter the water used in the automatic humidifying function of the refrigerator. This filter element can filter water with a certain water flow rate and can be used in the high-temperature environment of the compressor compartment of the refrigerator without the problem of the housing cracking. At the same time, the outer shell of this filter element has a high light transmittance, and the use situation of the filter element can be directly observed, so that it can be replaced according to the use situation, thereby meeting the application requirements of refrigerator products.

[0061] In some embodiments of this application, the filter packing includes calcium and magnesium ion purification resin and glass microspheres. Figure 2The structural schematic diagram of the filter element provided by this application is as follows Figure 2 As shown, the filter element includes the above-mentioned housing and the calcium and magnesium ion purification resin and glass microspheres filled in the housing, wherein the calcium and magnesium ion purification resin and glass microspheres are evenly dispersed in the housing. When the calcium and magnesium ion purification resin is used as the filtering filler, the calcium and magnesium ion purification resin can adsorb impurities in water, and the color of the calcium and magnesium ion purification resin will gradually deepen with use, so that the usage condition of the filter element can be clearly observed. In addition, by adding glass microspheres to the filler in this application, the contact area between the calcium and magnesium ion purification resin and water can be further increased, and the purification effect of the calcium and magnesium ion purification resin on water can be improved to a greater extent. Moreover, the light refraction effect of the glass microspheres can improve the obviousness of the color change of the calcium and magnesium ion purification resin, so as to more intuitively show the usage condition of the filter element.

[0062] This application does not limit the diameter of the glass microspheres, which can be selected according to actual situations. Considering cost and light refractive index, it is preferred that the diameter of the glass microspheres is 0.5 - 1 mm.

[0063] The glass microspheres of this application can be prepared by the following preparation method: After cleaning and screening the glass raw materials, heating and melting them, then dropping the molten glass into the cooling area. During the cooling process, the glass will form small particles and solidify to obtain glass microspheres.

[0064] The glass microspheres of this application can use waste glass or glass fragments as raw materials, and the cost of this glass microsphere is low and the preparation method is simple.

[0065] In some embodiments of this application, the mass ratio of the calcium and magnesium ion purification resin to the glass microspheres is 10:(1 - 3). When the mass ratio of the calcium and magnesium ion purification resin to the glass microspheres is within the above range, the content of the calcium and magnesium ion purification resin and the glass microspheres match each other, the contact area between the calcium and magnesium ion purification resin and water is larger, the water purification effect of the prepared filter element is better, and at the same time, the obviousness of the color change of the calcium and magnesium ion purification resin is higher, and the usage condition of the filter element is more intuitive.

[0066] In the fifth aspect, the embodiment of this application provides a refrigerator including the aforementioned filter element.

The refrigerator includes a box body having an accommodation cavity, a door body connected to the box body to open and close the accommodation cavity, and a refrigeration device for supplying cold air to the accommodation cavity. The box body includes an inner liner that defines the accommodation cavity, an outer shell connected to the outside of the inner liner to form the appearance of the refrigerator, and a heat insulation layer provided between the inner liner and the outer shell to insulate the accommodation cavity.

[0068] The box body defines a plurality of accommodating cavities. In this embodiment, the plurality of accommodating cavities may include a refrigerating chamber and a freezing chamber located below the refrigerating chamber. It should be noted that the types and settings of the plurality of accommodating cavities of the refrigerator are not limited to this.

[0069] A pick-and-place opening is formed at the front end of the accommodating cavity. Users can place food into the accommodating cavity or take out food from the accommodating cavity through this pick-and-place opening. A rotatable door body is provided on the box body to open or close the pick-and-place opening of the accommodating cavity. For example, the door body is rotatably connected to the box body by a hinge assembly located at the upper part of the refrigerator and a hinge assembly located at the lower part of the refrigerator.

[0070] A humidifying member is provided in the accommodating cavity of the box body. The humidifying member can be used to humidify the air in the accommodating cavity, solve the problem that the food materials in the accommodating cavity are prone to drying, and improve the freshness preservation effect of the refrigerator. Among them, the humidifying member can be provided in the refrigerating chamber.

[0071] In this embodiment, a water supply member can also be provided in the accommodating cavity. The water outlet of the water supply member is communicated with the water inlet of the humidifying member through a pipeline. The water supply member can supply water to the humidifying member. A filter element can be provided in the pipeline, that is, the housing of the filter element includes an inlet and an outlet, and both the inlet and the outlet are communicated with the pipeline. When the water flowing out from the water outlet of the water supply member flows through the filter element, it can enter the cavity of the housing through the inlet to filter the filler, and after being filtered by the filter filler, it flows out from the outlet to the humidifying member. In this way, impurities in the water provided to the humidifying member can be removed, avoiding the deposition of impurities in the humidifying member and affecting the service life of the humidifying member. And, the filtered water acts through the humidifying member to improve the freshness preservation function of the refrigerator.

[0126] Test Example

[0127] The heat resistance performance of the ABS materials prepared in the examples and comparative examples was tested according to the method of GB / T 1633 standard for plastics heat resistance performance, and the heat resistance performance was obtained.

[0128] The pressure resistance performance of the ABS materials prepared in the examples and comparative examples was tested according to the national standard of water pressure GB / T 4744, and the pressure resistance performance was obtained.

[0129] The light transmittance of the ABS materials prepared in the examples and comparative examples was tested with reference to ASTM D1003 and GB / T 2410-80, and the light transmittance was obtained; the light transmittance refers to the ratio of the light flux transmitted through the specimen to the light flux incident on the specimen.

[0130] The water hardness of the filter elements prepared in the examples and comparative examples was tested, and the removal rate of calcium and magnesium ions was obtained, which was the water purification ability of the filter element.

[0131] The filter elements prepared in the examples and comparative examples were tested with a color difference meter. After the filter elements continuously purified 40 L of hard water with a calcium carbonate mass concentration of 300 mg / L, the color difference value (△E) was obtained. The early, middle, and late stages were determined according to the △E range: 0 - 8 was the early stage, 9 - 16 was the middle stage, 17 - 25 was the late stage, and when it was greater than 25, it needed to be replaced.

[0132] The results are shown in Table 1.

[0133] Table 1 Test Results of Examples 1 - 12 and Comparative Examples 1 - 10

[0134]

[0135] By comparing Examples 1 - 12 and Comparative Examples 1 - 10, it can be found that when the ABS material is prepared according to the mass percentage content: 77.5 - 85% ABS resin, 10 - 15% heat - resistant and pressure - resistant regulator, 3 - 6% transparent nucleating agent, 0.2 - 1% high - temperature toughening agent, and 0.1 - 0.5% lubricant, the prepared ABS material has high heat - resistant performance, high pressure - resistant performance, and high light transmittance; according to the comparison between Examples 1, 5 - 7, it can be known that when the heat - resistant and pressure - resistant regulator includes 10 - 25% nylon 6 and 75 - 90% styrene - acrylonitrile - butadiene rubber, the heat - resistant performance, pressure - resistant performance, and light transmittance of the ABS material are higher; according to the comparison between Example 1 and Example 8, it can be known that when the transparent nucleating agent includes styrene - acrylate copolymer, butadiene, methacrylate, and sorbitol, and the mass ratio of styrene - acrylate copolymer, butadiene, methacrylate, and sorbitol is 1:3:2:0.5, the ABS material has higher heat - resistant performance, pressure - resistant performance, and light transmittance; according to the comparison between Examples 1 and 12, when the filter element is filled with calcium - magnesium ion purification resin and glass microspheres according to a mass ratio of 10:(1 - 3), the change in the measured color difference value of the filter element color is greater, which is beneficial to observing the replacement time of the filter element.
