Embodiment 1

[0022] Prepare raw materials according to the following proportions, and the polymerization method is solution polymerization

[0023]

[0024] Dissolve azobisisobutyronitrile in styrene, then add glycidyl methacrylate, mix evenly and introduce it into the flask, then pour 45ml of dried toluene, add a magnet, connect a spherical condenser, vacuumize, nitrogen Protect. The reaction temperature was controlled at 90°C, condensed water was introduced, and the reaction time was 12 hours. Take 80ml of ethanol for precipitation, and after the precipitation is allowed to stand still, remove the upper layer liquid to obtain the bottom layer precipitation, and add 50ml of dichloromethane for secondary dissolution. After the solution is completely dissolved, slowly drop the solution into 80ml of methanol to obtain a white powdery precipitate and pour it into a Buchner funnel for vacuum filtration. After the white precipitate is obtained, put it into a watch glass, and put the product...

Embodiment 2

[0027] Prepare the raw materials according to the following proportions, and the polymerization method is suspension polymerization

[0029]

[0030] Add 1200ml of desalted water into a 3000ml three-necked bottle, raise the temperature to 85°C, add 6g of polyvinyl alcohol, and start stirring until the polyvinyl alcohol is completely dissolved. Measure methyl styrene, glycidyl acrylate, and dibenzoyl peroxide in proportion, mix them evenly, add them into a three-necked bottle, and stop the reaction after 7 hours of reaction. Wash thoroughly with hot desalinated water to remove dispersants and monomers attached to the surface, and then dry for use.

[0031] Mix the obtained copolymer with industrial SAM in a high-speed mixer and add it to a twin-screw extruder. The temperature of the extruder is set between 180°C and 220°C, and the mixture melts and reacts at this temperature. The required compatibilizer is obtained by extruding strands, cooling and granulating, ...

[0033] Prepare the raw materials according to the following proportions, and the polymerization method is bulk polymerization

[0034]

[0035] Styrene, glycidyl methacrylate, and dibenzoyl peroxide were weighed in proportion, mixed evenly and poured into a three-necked bottle, vacuumed, nitrogen protection, condensed water, heated to 80°C in an oil bath, and reacted After 1 hour, react in a water bath at 60°C for 12 hours to obtain a polymer.

[0036] Mix the obtained copolymer with industrial SAM in a high-speed mixer and add it to a twin-screw extruder. The temperature of the extruder is set between 180°C and 220°C, and the mixture melts and reacts at this temperature. The required compatibilizer is obtained by extruding strands, cooling and granulating, and drying.

Abstract

The invention provides a macromolecular compatilizer for ABS (acrylonitrile-butadiene-styrene)-HIPS (high impact polystyrene) alloys and a preparation method of the macromolecular compatilizer. The compatilizer comprises components in percentage by weight as follows: styrene monomers, glycidyl acrylate monomers, a free radical initiator and SAM (styrene-maleic anhydride-acrylonitrile). The preparation method comprises steps as follows: the styrene monomers, the glycidyl acrylate monomers and the free radical initiator react with a polymerization method, and a copolymer is obtained; the copolymer is uniformly mixed with SAM, and the macromolecular compatilizer for the ABS-HIPS alloys is obtained with a melt blending method. The macromolecular compatilizer has the benefits as follows: the amphipathic macromolecular compatilizer is obtained through one-step reaction and melt blending, a preparation process is simple, the proportion of polystyrene chain segments to SAM chain segments in the compatilizer is better adjusted, and the macromolecular compatilizer is suitable for blending systems of ABS and HIPS in various proportions. Experiment results show that the compatilizer has a remarkable compatibilization effect.

Description

technical field [0001] The invention relates to a macromolecular compatibilizer for ABS-HIPS alloy and a preparation method thereof, belonging to the technical field of plastic compatibilizers. Background technique [0002] The mechanical properties of the products obtained by blending incompatible polymers are usually poor, mostly due to the weak interfacial bonding force between the phases and the large particle size of the dispersed phase. At present, the common method in plastic modification industry is to add compatibilizer. The addition of a small amount of compatibilizer can enhance the interfacial bonding force and refine the particle size of the dispersed phase to obtain a product with better mechanical properties. At present, the compatibilizer can be block polymerization, graft polymerization or random copolymer. [0003] Acrylonitrile-butadiene-styrene copolymer (ABS) and high-impact polystyrene (HIPS) have excellent mechanical properties and are easy to form a...
