Description

An ABS composite material, its preparation method and application Technical Field

[0001] This application belongs to the field of composite material technology, specifically relating to an ABS composite material, its preparation method, and its application. Background Technology

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

[0003] In recent years, with the improvement of living standards, people have increasingly higher requirements for the comfort of their living environment, as reflected in the rise of kitchen air conditioners. However, the high-temperature oil fumes generated during cooking adhere to relevant parts, causing significant problems for air conditioner use. Oil fumes not only affect the cooling efficiency of the air conditioner but also corrode components, leading to breakage during operation and reducing the lifespan of the air conditioner. Currently, common solutions include coatings, films, and the use of more oil-resistant alloy materials. Coatings and films can improve oil resistance and stain resistance, but the processes are complex and inefficient; alloys can mitigate the corrosive effects of oil fumes but are less effective at preventing oil stains.

[0004] Therefore, how to provide an ABS composite material with better oil resistance and better resistance to oil stain adhesion has become an urgent technical problem to be solved. Summary of the Invention

[0005] This application provides an ABS composite material, its preparation method, and its application. By designing the components of the ABS composite material and further utilizing the synergistic effect of polypropylene (PP) and a silicon-containing polymer, this application prepares an ABS composite material with good oil resistance and good resistance to oil stain adhesion.

[0006] In a first aspect, this application provides an ABS composite material, the ABS composite material comprising the following components in parts by weight:

[0007] Styrene-acrylonitrile copolymer (SAN) 64-80 parts, ABS high-resin powder 21-35 parts, silicone-containing polymer 0.4-3.2 parts, PP 0.8-5.5 parts, and compatibilizer 1.5-5.5 parts;

[0008] Under conditions of 2.16 KG and 190℃, the melt index of the PP is 270-2100 g / 10min.

[0009] This application designs the components of ABS composite materials and further utilizes the synergistic effect of PP and silicon-containing polymers to prepare ABS composite materials with good oil resistance and good resistance to oil stain adhesion.

[0010] In this application, by introducing PP and silicon-containing polymers into the ABS composite material system and adding an appropriate amount of compatibilizer, PP migrates to the ABS surface to form a film during molding, and the silicon-containing polymer also migrates to the surface, so that the ABS composite material plays a good role in isolating oil corrosion. At the same time, after PP migrates to the ABS surface to form a film and the silicon-containing polymer migrates to the ABS surface, the surface energy of the composite material system is reduced, which greatly improves the oil resistance of the ABS composite material.

[0011] In this application, by controlling the amounts of silicone polymer and PP within specific ranges, an ABS composite material with good oil resistance and good oil adhesion resistance was prepared. If the amount of silicone polymer is too small, the surface energy of the ABS composite material is large, resulting in poor oil adhesion resistance; if the amount of silicone polymer is too large, the overall performance of the ABS composite material is poor. If the amount of PP is too small, it is difficult to form a complete barrier film on the ABS surface, resulting in poor oil resistance and oil adhesion resistance of the ABS composite material; if the amount of PP is too large, delamination, whitening, and other appearance defects are likely to occur during subsequent molding, resulting in poor overall performance of the ABS composite material.

[0012] In this application, by controlling the melt flow index of PP within a specific range, an ABS composite material with good oil resistance and resistance to oil stain adhesion was prepared. If the melt flow index of PP is too high, PP will easily migrate to the ABS surface during molding, and the PP enriched layer formed on the surface of the ABS composite material will be easily wiped away, resulting in poor long-term oil stain resistance. If the melt flow index of PP is too low, it will be difficult to form a PP enriched layer on the surface of the ABS composite material, resulting in poor oil resistance and resistance to oil stains.

[0013] In this application, with the ABS composite material as 100% by mass, the SAN by mass 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 unlisted values ​​within the range are also applicable, and it can also be any combination of the aforementioned values, preferably 62%-67%.

[0014] In this application, under the conditions of 2.16 KG and 190℃, the melt index of the PP is 270-2100 g / 10min, for example, it can be 270 g / 10min, 300 g / 10min, 400 g / 10min, 500 g / 10min, 700 g / 10min, 900 g / 10min, 1000 g / 10min, 1200 g / 10min, 1500 g / 10min, 1800 g / 10min, 2000 g / 10min or 2100 g / 10min, but is not limited to the listed values. Other unlisted values ​​within the value range are also applicable, and it can also be any combination of the aforementioned values.

[0015] It should be noted that the melt flow index test method for PP in this application refers to the national standard ISO 1133, with a load of 2.16 KG and a test temperature of 190℃.

[0016] It should be noted that in this application, ABS is an acrylonitrile-butadiene-styrene polymer, SAN is a styrene-acrylonitrile copolymer, PP is polypropylene, and ABS high-adhesion powder is a terpolymer powder composed of styrene, butadiene, and acrylonitrile.

[0017] In this application, the weight percentage 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. Other unlisted values ​​within the range of values ​​are also applicable, and it can also be any combination of the aforementioned values.

[0018] The ABS composite material contains 21-35 parts by weight of ABS high-rubber powder, for example, 21, 22, 24, 25, 27, 30, 32, 34 or 35 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable, and it can also be any combination of the aforementioned values.

[0019] The weight percentage 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 part, 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.

[0021] The compatibilizer in the ABS composite material is 1.5-5.5 parts by weight, 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. Other unlisted values ​​within the range are also applicable, and it can also be any combination of the aforementioned values.

[0022] The following are preferred technical solutions of this application, but are not intended to limit the technical solutions provided in this application. The purpose and beneficial effects of this application can be better achieved through the following preferred technical solutions.

[0023] As a preferred technical solution of this application, with the mass content of SAN being 100%, the mass percentage content 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. Other unlisted values ​​within the range of values ​​are also applicable, and it can also be any combination of the aforementioned values.

[0024] In this application, an ABS composite material with good oil resistance and resistance to oil stain adhesion was prepared by selecting SAN with a specific acrylonitrile content. If the acrylonitrile content in the SAN is too low, the oil resistance of the matrix material itself is poor; if the acrylonitrile content in the SAN is too high, the prepared ABS composite material will turn yellow, affecting its use and appearance.

[0025] In this application, the mass percentage of acrylonitrile in SAN is determined by elemental analysis. Specifically, the mass fraction of nitrogen is determined by elemental analysis and the acrylonitrile content is calculated using the following formula: acrylonitrile mass percentage = 53X / 14.

[0026] Preferably, the weight-average molecular weight of the SAN is 40,000-140,000 g / mol, for example, it can be 40,000 g / mol, 50,000 g / mol, 60,000 g / mol, 70,000 g / mol, 80,000 g / mol, 90,000 g / mol, 100,000 g / mol, 110,000 g / mol, 120,000 g / mol, 130,000 g / mol or 140,000 g / mol, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable, and it can also be any combination of the aforementioned values. More preferably, it is 90,000-120,000 g / mol.

[0027] It should be noted that the weight-average molecular weight of SAN was tested using GPC (gel permeation chromatography).

[0028] As a preferred technical solution of this application, the grafting rate of the ABS high-adhesion 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 value range are also applicable, and it can also be any combination of the aforementioned values, preferably 45-55%.

[0029] In this application, an ABS composite material with good oil resistance and resistance to oil stain adhesion was prepared by selecting ABS high-grafting ABS powder with a specific grafting rate. If the mass content of the grafting rate in the ABS high-grafting ABS powder is too low, it will lead to poor compatibility between SAN and the ABS high-grafting ABS powder; if the mass content of the grafting rate in the ABS high-grafting ABS powder is too high, the high-grafting ABS powder is prone to agglomeration. Both of these will lead to poor stability of the elongation at break of the ABS resin itself, affecting the oil resistance assessment.

[0030] It should be noted that, in this application, the grafting rate of ABS high-resin powder refers to the mass percentage of SAN in ABS high-resin powder.

[0031] In this application, the grafting rate of ABS high-polymer powder was tested using the following method: A mass of ABS high-polymer powder (containing Y% polybutadiene rubber (PB)) was weighed (M0), extracted multiple times by centrifugation with acetone, and the supernatant was collected in a dish (mass M1), dried, and weighed (mass M2). The grafting rate was then calculated using the following formula:

[0032]

[0033] As a preferred technical solution of this application, the silicon-containing polymer is selected from any one or a combination of at least two of organosilicon wax, alkoxy silicone oil or silicone resin.

[0034] Preferably, the weight-average molecular weight of the silicon-containing polymer is 1400-21000 g / mol, for example, it can be 1400 g / mol, 1500 g / mol, 2000 g / mol, 4000 g / mol, 6000 g / mol, 8000 g / mol, 10000 g / mol, 12000 g / mol, 14000 g / mol, 16000 g / mol, 18000 g / mol, 20000 g / mol or 21000 g / mol, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable, and it can also be any combination of the aforementioned values. More preferably, it is 4000-10000 g / mol.

[0035] In this application, by controlling the weight-average molecular weight of the silicon-containing polymer within a specific range, an ABS composite material with good oil resistance and resistance to oil stain adhesion was prepared. If the weight-average molecular weight of the silicon-containing polymer is too small, the migration rate of the silicon-containing polymer during the molding process is relatively fast, resulting in poor long-term resistance to oil stain adhesion 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, leading to poor oil resistance and resistance to oil stain adhesion.

[0036] The weight-average molecular weight of the silicon-containing polymer was determined using GPC (gel permeation chromatography).

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

[0039] It should be noted that the melt flow index test method for PP in this application refers to the national standard ISO 1133, with a load of 2.16 KG and a test temperature of 190℃.
