example 1

[0033] 1) Preparation of grafts

[0034] Dissolve 0.3% dicumyl peroxide initiator, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester antioxidant 1% into 4% methyl In the glycidyl acrylate, stir on a high-speed kneader for 2 minutes, then add the dried 94.5% ABS into the high-speed kneader, and stir for 4 minutes to form a mixture for later use. Put the stirred mixture in the banburying chamber of the torque rheometer for melting and banburying. The technological conditions are: temperature: 220°C, rotating speed: 100r / min, banburying time: 10min. The relationship between torque and time during the banburying process is shown in figure 1 , wherein curve A is the curve of torque changing with time during the banburying process of pure ABS, and curve B is the curve of torque changing with time in this example. It can be seen from curve B that the reaction peak appears at 50-100s, indicating that glycidyl methacrylate and styrene are successfully g...

example 2

[0041] On the basis of example 1, the consumption of changing glycidyl methacrylate is 6%, the consumption of dicumyl peroxide initiator is 0.4%, and other conditions are unchanged to carry out grafting reaction. figure 1 Middle curve C is the torque curve of this example 2 with time, figure 2 Middle curve C is graft infrared spectrogram in this example 2, image 3 Middle curve C is the dynamic rheological curve of the graft in Example 2.

[0042] According to the infrared spectrum, it can be seen that 1731cm -1 The strong vibrational absorption peak is the characteristic absorption peak of the carbonyl group (C=O) in the GMA molecule, at 967, 910, 846cm -1 The three weak continuous vibration peaks that exist at are the skeleton vibration peaks of the epoxy group in the GMA molecule, which also prove that GMA is successfully grafted onto ABS. From the dynamic rheological curve C, it can be seen that the reaction peak appeared at 60-120s, indicating that glycidyl methacryla...

[0044] On the basis of example 1, the consumption of changing glycidyl methacrylate is 8%, the consumption of dicumyl peroxide initiator is 0.5%, and other conditions are unchanged to carry out grafting reaction. figure 1 Middle curve D is the torque curve with time of this example 3, figure 2 Middle curve D is graft infrared spectrogram in this example 3, image 3 The middle curve D is the dynamic rheological curve of the graft in Example 3.

[0045] According to the infrared spectrum, it can be seen that 1731cm -1 The strong vibrational absorption peak is the characteristic absorption peak of the carbonyl group (C=O) in the GMA molecule, at 967, 910, 846cm -1 The three weak continuous vibration peaks that exist at are the skeleton vibration peaks of the epoxy group in the GMA molecule, which also prove that GMA is successfully grafted onto ABS. From the dynamic rheological curve C, it can be seen that the reaction peak appeared at 70-120s, indicating that glycidyl methac...

Abstract

The invention discloses an ABS melt-grafting glycidyl methacrylate and a preparation method thereof. The ABS melt-grafting glycidyl methacrylate is characterized in that the ABS-g-GMA is prepared by the following components, by weight, 86-99.7% of ABS, 0.1-11% of GMA, 0.1-1% of an initiator, and 0.1-2% of an antioxidant. The preparation method comprises that: the glycidyl methacrylate is directlysubjected to melt-grafting on the ABS to form an acrylonitrile-butadiene-styrene terpolymer grafted glycidyl methacrylate graft, wherein the grafting rate of the glycidyl methacrylate is 0.1-3%. According to the present invention, the ABS melt-grafting glycidyl methacrylate can be adopted for compatibilizers of the blend of the ABS and polycarbonate, the blend of the ABS and a polyester, the blend of the ABS and nylon, the blend of the ABS and polyurethane, and other blends, such that the comprehensive properties of the blends can be effectively improved. The method of the present invention has a simple process, and is applicable for the large-scale production.

Description

technical field [0001] The invention belongs to the technical field of macromolecular materials, and relates to a kind of melting preparation of acrylonitrile-butadiene-styrene terpolymer (ABS)-grafted glycidyl methacrylate (ABS-g-GMA) graft and its preparation method. Background technique [0002] ABS is a general term for a series of polymers synthesized based on three monomers of acrylonitrile (A), butadiene (B) and styrene (S). Since its development in the 1940s, it has been widely used in the machinery industry and automobile industry because of its balanced mechanical properties such as toughness, hardness, and rigidity, excellent electrical properties, wear resistance, dimensional stability, and surface gloss. , Electronic and electrical industry, instrumentation industry, textile industry and construction industry. [0003] However, due to the poor weather resistance and heat resistance of ABS, its application is limited to a certain extent. In order to make full ...
