Description
Technical Field
The invention relates to the field of modification of acrylonitrile-butadiene-styrene (ABS), in particular to an ABS/PMMA alloy material with antistatic property and a preparation method thereof.
Background
ABS is widely used in automobiles, white goods, electronics, and the like as one of the most common general-purpose plastics. ABS is an engineering plastic with excellent comprehensive performance, and has excellent impact resistance, low-temperature performance, chemical resistance, wear resistance, dimensional stability and other aspects, but ABS also has some defects, such as high melt viscosity, poor fluidity, poor thermal stability and weather resistance. In order to ameliorate the above disadvantages, attempts have been made to use ABS modifying materials that take advantage of the ABS material while also alleviating or avoiding some of the above disadvantages.
Polymethyl methacrylate (PMMA) is an engineering plastic with good optical performance, excellent weather resistance, good mechanical strength and high transparency, but PMMA has low impact strength and is particularly sensitive to notches. The art has attempted to melt blend ABS with PMMA to avoid the respective drawbacks, for example CN102061056A discloses mixing ABS with PMMA and additives such as antistatic agents to provide plastic alloys with antistatic properties, good gloss and easy processing. However, the ABS/PMMA alloy disclosed in CN102061056A, although improved in conductivity, did not improve or even slightly decrease in mechanical properties. Such ABS/PMMA alloys have been limited in many practical applications.
In this regard, CN104629246A attempts to improve the toughness and wear resistance of the alloy material while maintaining the antistatic property, however, this invention adopts a large amount of methyl methacrylate-butadiene-styrene copolymer (MBS) and styrene-acrylonitrile copolymer (SAN) to improve the toughness of the alloy material. These additives not only increase the process complexity and/or the production costs, but also cause problems of miscibility between the various material phases and even the occurrence of hard spots.
In view of the above, the present application provides an ABS/PMMA alloy material which can address one or more deficiencies still remaining in the art.

Detailed Description
Hereinafter, the content of the present application will be further explained according to specific embodiments. However, the specific embodiments listed are for illustrative purposes only and are not intended to limit the scope of the present application. Those skilled in the art will recognize that a particular feature in any of the embodiments below may be used in any other embodiment without departing from the spirit of the present application.
In one embodiment, the antistatic grade alloy material consists of the following components: 65 to 75% by weight of acrylonitrile-butadiene-styrene; 20 to 30% by weight of polymethyl methacrylate; 5 to 10% by weight of an antistatic agent; and the balance optionally other additives. The inventor finds that when ABS and PMMA are mixed according to a specific proportion, the strength and toughness of the alloy material can be obviously improved even without using additional additives, so that the alloy material can be directly suitable for various applications such as computer shell plates, automobile interior plates and the like.
More specifically, the inventors of the present invention have found through extensive research and experiments that the melt index of ABS used for the alloy can be 1.7 to 3.2g/10min, and the melt index of PMMA can be 12 to 15g/10 min. All melt indices herein are measured according to ASTM D1238 at a temperature of 200 ℃ and a load of 5 kg. Further, the specific gravity of the ABS can be 1.05-1.08 g/cm3And is andthe specific gravity of PMMA is 1.17-1.19 g/cm3。
In a preferred embodiment, the ABS has a melt index of 1.8 to 3.0g/10min, more preferably 2.2 to 2.6g/10min, and the PMMA has a melt index of 13.5 to 14.0g/10 min. Alloys resulting from compounding such ABS and PMMA in specific ratios can achieve better hardness and strength than alloys resulting from compounding in other ratios or from compounding other types of ABS/PMMA, and such alloys have better strength and toughness after stretching.
In a further embodiment, the weight ratio of ABS to PMMA is 3-3.5: 1, for example, ABS accounts for 68-73% of the total alloy mass and PMMA accounts for 20-25% of the total alloy mass. More preferably, the weight ratio of ABS to PMMA is 3.0: 1; 3.1: 1; 3.2: 1; 3.3: 1; 3.4: 1; or 3.5: 1. in preferred embodiments, ABS comprises 68%, 69%, 70%, 71%, 72% or 73% of the total alloy mass and PMMA comprises 21%, 22%, 23% or 24% of the total alloy mass.
Although the above mechanism cannot be clearly explained at present, the applicant believes that since the specific PMMA and the specific ABS are compounded in the above ratio, the balance between hardness and toughness can be achieved, so that the formed alloy can meet the actual production demand without using an additive. Through a large number of experiments and summaries, in the practical application of manufacturing computer shell plates, automobile interior panels and the like, the alloy obtained by mixing ABS with the melt index of 1.7-3.2 g/10min and PMMA with the melt index of 12-15 g/10min according to the proportion can realize the balance between proper strength and toughness, is simple enough in the processing process, and does not need to use any additional additive or auxiliary agent.
In one embodiment, the ABS may be blended with several types of ABS, such as two types of ABS. In this embodiment, the two ABS's have melt indices of 1.8-2.0 g/10min and 2.8-3.0 g/10min, respectively, and the ratio is 3: 1 to 1: 3, e.g. 1: 2; 1: 1; or 2: 1. for example, the ABS component is formed by mixing two types of ABS, and the melt index is 1.8-2.0 g/10min and 2.8-3.0 g/10min respectively, and the proportion of the two types of ABS is only required to enable the melt index of the total ABS component to be 1.7-3.2 g/10 min.
In one embodiment, the antistatic agent is a nonionic antistatic agent or an anionic antistatic agent. For example, a nonionic antistatic agent having a polyether structure or an amide structure (such as ethylene glycol lauramide), or an anionic antistatic agent such as an alkylsulfonate, phosphate, or alkylsulfate. In this embodiment, the antistatic agent may be present in an amount of 8 wt% and uniformly dispersed within the matrix composed of ABS and PMMA, and thus articles made from the alloy of the present invention can have a permanent antistatic effect. In another embodiment, other additives that may optionally be present include lubricants, antioxidants, tougheners, fillers, colorants, antiwear agents, and the like.
In one embodiment, a method of making an antistatic grade alloy material comprises: providing a mixture comprising ABS, PMMA, antistatic agent and optionally other additives, preferably the mixture consists only of ABS, PMMA and antistatic agent; subjecting the mixture to melt homogenization to obtain a molten alloy material; and cooling the molten alloy material to obtain the antistatic alloy material. In a further embodiment, ABS, PMMA and antistatic agent may be mixed in the above weight ratio and baked at a temperature of 80 to 90 ℃ for 2 to 4 hours. Subsequently, the mixture is added into one of a single screw, a double screw and an open mill, and shearing homogenization is carried out at the temperature of 245-280 ℃.
