Description

Technical Field

[0001] The invention belongs to the technical field of composite materials, and in particular relates to an ABS composite material and a preparation method and application thereof. Background Art

[0002] ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B) and styrene (S). It is a "tough, hard and rigid" material with easy-to-obtain raw materials, good comprehensive performance, low price and wide application. It has good dimensional stability and has been widely used in home appliances, tools, automobiles and communications. Especially in kitchen appliances among home appliances, it is increasingly widely used as a shell due to its good comprehensive performance and excellent appearance.

[0003] In recent years, with the improvement of material living standards, people have higher and higher requirements for the comfort of their environment, and the rise of kitchen air conditioners is a good reflection of this. However, the high-temperature oil smoke generated during cooking adheres to relevant parts, which will cause great trouble to the use of air conditioners. The oil smoke will not only affect the cooling efficiency of the air conditioner, but also corrode and cause air conditioner components, resulting in breakage during the operation of the air conditioner, and reduce the life of the air conditioner. At present, the common treatment methods are coating, lamination and the use of alloy materials with better oil resistance. Coating and lamination can improve the oil resistance and oil stain resistance, but the treatment process is complicated and inefficient; alloys can improve the erosion of oil smoke, but it is difficult to improve the oil stain resistance effect.

[0004] Therefore, how to provide an ABS composite material with good oil resistance and good anti-oil adhesion has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide an ABS composite material and a preparation method and application thereof. The present invention designs the components of the ABS composite material and further prepares an ABS composite material with good oil resistance and good anti-oil stain adhesion through the synergistic effect of PP (polypropylene) and a silicon-containing polymer.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present invention provides an ABS composite material, wherein the ABS composite material comprises the following components in parts by weight:

[0008]

[0009] Under the conditions of 2.16KG and 190°C, the melt index of the PP is 270-2100g / 10min.

[0010] The present invention designs the components of the ABS composite material, and further prepares the ABS composite material with good oil resistance and good anti-oil stain adhesion through the synergistic effect of PP and the silicon-containing polymer.

[0011] In the present invention, PP and silicon-containing polymer are introduced into the ABS composite material system, supplemented with an appropriate amount of compatibilizer, so that during molding, PP migrates to the surface of ABS to form a film, and the silicon-containing polymer also migrates to the surface, so that the ABS composite material has a good isolation effect on oil corrosion; at the same time, during molding, PP migrates to the surface of ABS to form a film, and after the silicon-containing polymer migrates to the surface of ABS, the surface energy of the composite material system is reduced, so that the anti-oil pollution performance of the ABS composite material is greatly improved.

[0012] In the present invention, an ABS composite material with good oil resistance and good oil resistance adhesion is prepared by further controlling the dosage of the silicon-containing polymer and PP within specific ranges. If the dosage of the silicon-containing polymer is too small, the surface energy of the ABS composite material is large, and the oil resistance and adhesion are poor; if the dosage of the silicon-containing polymer is too large, the comprehensive performance of the ABS composite material is poor; if the dosage of PP is too small, it is difficult to form a complete insulating film on the ABS surface, so that the oil resistance and oil resistance adhesion of the ABS composite material are poor; if the dosage of PP is too large, appearance defects such as delamination and whitening are likely to occur during subsequent molding, resulting in poor comprehensive performance of the ABS composite material.

[0013] In the present invention, an ABS composite material with good oil resistance and oil stain resistance is prepared by controlling the melt index of PP within a specific range. If the melt index of PP is too large, PP is easy to migrate to the ABS surface during molding, and the PP enriched layer formed on the surface of the ABS composite material is easy to be wiped off, and the long-term oil stain resistance is poor; if the melt index of PP is too small, it is difficult to form a PP enriched layer on the surface of the ABS composite material, resulting in poor oil resistance and oil stain resistance.

[0014] In the present invention, taking the mass percentage of the ABS composite material as 100%, the mass percentage of the SAN is 60% to 75%, for example, it can be 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74% or 75%, but is not limited to the listed values. Other values ​​not listed within the numerical range are also applicable. It can also be any combination of the aforementioned values, preferably 62%-67%.

[0015] In the present invention, under the conditions of 2.16KG and 190°C, the melt index of the PP is 270-2100g / 10min, for example, it can be 270g / 10min, 300g / 10min, 400g / 10min, 500g / 10min, 700g / 10min, 900g / 10min, 1000g / 10min, 1200g / 10min, 1500g / 10min, 1800g / 10min, 2000g / 10min or 2100g / 10min, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable, and it can also be the range of any combination of the aforementioned values.

[0016] It should be noted that the test method for the melt index of PP in the present invention refers to the national standard ISO 1133, the load is 2.16KG, and the test temperature is 190°C.

[0017] It should be noted that, in the present invention, ABS is acrylonitrile-butadiene-styrene polymer, SAN is styrene-acrylonitrile copolymer, and PP is polypropylene.

[0018] In the present invention, the weight proportion of SAN in the ABS composite material is 64-80 parts, for example, it can be 64 parts, 65 parts, 66 parts, 68 parts, 70 parts, 72 parts, 74 parts, 76 parts, 78 parts, 79 parts or 80 parts, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable, and it can also be a range of any combination of the aforementioned numerical values.

[0019] The weight proportion of ABS high-rubber powder in the ABS composite material is 21-35 parts, for example, it can be 21 parts, 22 parts, 24 parts, 25 parts, 27 parts, 30 parts, 32 parts, 34 parts or 35 parts, but is not limited to the listed values. Other unlisted values ​​within the numerical range are also applicable, and it can also be a range of any combination of the aforementioned values.

[0020] The weight proportion of the silicon-containing polymer in the ABS composite material is 0.4-3.2 parts, for example, it can be 0.4 parts, 0.5 parts, 0.7 parts, 1 parts, 1.2 parts, 1.4 parts, 1.6 parts, 1.8 parts, 2 parts, 2.2 parts, 2.4 parts, 2.6 parts, 2.8 parts, 3 parts or 3.2 parts, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable, and it can also be a range of any combination of the aforementioned numerical values.

Other unlisted values ​​within the numerical range are also applicable, and it can also be a range of any combination of the aforementioned values.

[0022] The weight proportion of the compatibilizer in the ABS composite material is 1.5-5.5 parts, for example, it can be 1.5 parts, 2 parts, 2.2 parts, 2.5 parts, 2.7 parts, 3 parts, 3.3 parts, 3.6 parts, 3.8 parts, 4 parts, 4.2 parts, 4.4 parts, 4.6 parts, 4.8 parts, 5 parts or 5.5 parts, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable, and it can also be the range of any combination of the aforementioned values.

[0023] The following are preferred technical solutions of the present invention, but are not intended to limit the technical solutions provided by the present invention. Through the following preferred technical solutions, the objectives and beneficial effects of the present invention can be better achieved and realized.

[0024] As a preferred technical solution of the present invention, based on the mass content of SAN as 100%, the mass percentage of acrylonitrile in the SAN is 15-35%, for example, it can be 15%, 16%, 18%, 20%, 22%, 24%, 26%, 28%, 30%, 32%, 33% or 35%, but is not limited to the listed values, and other values ​​not listed within the numerical range are also applicable, and it can also be the range of any combination of the aforementioned values.

[0025] In the present invention, by selecting SAN with a specific acrylonitrile mass content, an ABS composite material with good oil resistance and oil stain adhesion resistance is prepared. If the acrylonitrile mass content in SAN is too low, the oil resistance of the base material itself is poor; if the acrylonitrile mass content in SAN is too high, the color of the prepared ABS composite material is yellow, which affects the use and appearance.

[0026] In the present invention, the mass percentage of acrylonitrile in SAN is determined by elemental analysis. The specific method is: by elemental analysis, the mass fraction X of N element is measured, and the acrylonitrile content can be calculated according to the following formula: mass percentage of acrylonitrile = 53X / 14.

[0027] Preferably, the weight average molecular weight of the SAN is 40,000-140,000, for example, 40,000, 50,000, 60,000, 70,000, 80,000, 90,000, 100,000, 110,000, 120,000, 130,000 or 40,000, but is not limited to the listed values. Other values ​​not listed in the numerical range are also applicable. It can also be any combination of the aforementioned values, and is more preferably 90,000-120,000.

[0028] It should be noted that the weight average molecular weight of SAN was measured using GPC (gel permeation chromatography).

[0029] As a preferred technical solution of the present invention, the grafting rate of the rubber powder in the ABS high rubber powder is 33-57%, for example, it can be 33%, 35%, 36%, 38%, 40%, 42%, 45%, 46%, 48%, 50%, 52%, 53%, 55% or 57%, but is not limited to the listed values. Other unlisted values ​​within the numerical range are also applicable. It can also be any combination of the aforementioned values, preferably 45-55%.

[0030] In the present invention, an ABS composite material with good oil resistance and oil stain adhesion resistance is prepared by selecting ABS high-rubber powder with a specific rubber powder grafting rate. If the mass content of the rubber powder grafting rate in the ABS high-rubber powder is too low, the compatibility of SAN and ABS high-rubber powder will be poor; if the mass content of the rubber powder grafting rate in the ABS high-rubber powder is too high, the high-rubber powder is easy to agglomerate, both of which will lead to poor stability of the elongation at break of the ABS resin itself, affecting the oil resistance evaluation.

[0031] It should be noted that, in the present invention, the grafting rate of rubber powder in ABS high-density rubber powder refers to the quality of SAN in ABS high-density rubber powder.

[0032] In the present invention, the grafting rate of the rubber powder in the ABS high-quality rubber powder is tested by the following method: weigh the high-quality rubber powder with a mass of M0 (the content of rubber PB in the rubber powder is Y%), use acetone for multiple centrifugal extractions, collect the clear liquid in a container (mass M1), dry it, and then weigh it (mass M2), and then calculate the grafting rate according to the following formula:

[0033] Grafting rate

[0034] As a preferred technical solution of the present invention, the silicon-containing polymer is selected from any one of silicone wax, alkoxy silicone oil or silicone resin, or a combination of at least two of them.

[0035] Preferably, the weight average molecular weight of the silicon-containing polymer is 1400-21000, for example, it can be 1400, 1500, 2000, 4000, 6000, 8000, 10000, 12000, 14000, 16000, 18000, 20000 or 21000, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable. It can also be the range of any combination of the aforementioned values, and is further preferably 4000-10000.

[0036] In the present invention, an ABS composite material with good oil resistance and oil stain adhesion resistance is prepared by controlling the weight average molecular weight of the silicon-containing polymer within a specific range. If the weight average molecular weight of the silicon-containing polymer is too small, the migration rate of the silicon-containing polymer is relatively fast during the molding process, resulting in poor long-term oil stain adhesion resistance of the ABS composite material; if the weight average molecular weight of the silicon-containing polymer is too large, the migration of the silicon-containing polymer is difficult, resulting in poor oil resistance and oil stain adhesion resistance.

[0037] The weight average molecular weight of the silicon-containing polymer was measured using GPC (gel permeation chromatography).

[0038] As a preferred technical solution of the present invention, the PP is homopolymer PP.

[0039] Preferably, at 2.16KG and 190°C, the melt index of the PP is 500-1500g / 10min, for example, it can be 500g / 10min, 700g / 10min, 900g / 10min, 1000g / 10min, 1200g / 10min or 1500g / 10min, but is not limited to the listed values. Other unlisted values ​​within the numerical range are also applicable, and it can also be the range of any combination of the aforementioned values.

[0040] It should be noted that the test method for the melt index of PP in the present invention refers to the national standard ISO 1133, the load is 2.16KG, and the test temperature is 190°C.

[0041] In the present invention, the comprehensive performance of the ABS composite material is further optimized and improved by further selecting PP with a specific melt index.

[0065] Example 1-Example 25 and Comparative Example 1-Comparative Example 8

[0066] Example 1 to Example 25 and Comparative Example 1 to Comparative Example 8 respectively provide an ABS composite material and a preparation method thereof. The specific composition of the ABS composite material is shown in Table 2-4 below (the amount of each component in Table 2-4 is in parts by weight);

[0067] The preparation method of ABS composite material is as follows:

[0068] The components of the ABS composite material are mixed and extruded and granulated using a twin-screw extruder to obtain the ABS composite material;

[0069] The temperature of the twin-screw extruder is divided into ten zones, the temperature of the first and second zones is 140°C, the temperature of the third to fifth zones is 200°C, and the temperature of the sixth to tenth zones is 180°C.

[0070] The performance of the ABS composite materials provided in the above embodiments and comparative examples was tested, and the specific testing method is as follows:

[0071] Oil resistance: The extruded pellets were injection molded into 15 1A type tensile specimens (total length 150 mm) according to GB / T 1040.2-2006. Ten specimens were placed on a tooling with a length of 145 mm at both ends. The specimens were kept in a bending stress state. The bending parts of 5 stressed specimens were immersed in blended oil, and the other 5 blank specimens were placed as a control. After the test for 72 hours, the elongation at break L1 of the stressed oil-immersed specimens and the elongation at break L0 of the stressed non-oil-immersed specimens were tested respectively. The elongation at break retention of the specimens was calculated according to the formula L1*100 / L0.

[0072] Anti-oil adhesion: Take another 5 injection-molded specimens, place them in the duct of a normally used range hood for one week, then take them out and wipe the oil stains on the surface of the specimens with a non-woven fabric to evaluate the difficulty of wiping the oil stains.

[0073] Long-term anti-oil performance: wipe the oil off the sample with non-woven cloth and place it in a constant temperature and humidity chamber at 80℃ and 90% humidity. Take it out and wipe the surface clean every week and put it back in. After 4 consecutive weeks, take it out and put it into a normally used range hood pipe. Fix it for one week and then take it out. Use non-woven cloth to wipe the oil on the surface of the sample to evaluate the difficulty of wiping the oil.

[0074] It should be noted that the difficulty of wiping off oil stains in the oil stain resistance test and long-term oil stain resistance is evaluated and divided into levels 1-5, among which level 5 means that the oil stain is easiest to wipe off, and level 1 means that the oil stain is most difficult to wipe off.

[0075] The range hoods normally used in the oil stain resistance test and the long-term oil stain resistance test refer to the condition of being normally turned on and used during the cooking process. In the data characterization of the following embodiments and comparative examples, the range hoods are used for the same length of time.
