Embodiment 1

[0018] Weigh 600 grams of ABS and dry at 90°C for 4 hours, then mix with 80 grams of decabromodiphenyl ether, 130 grams of N-phenylmaleimide, 50 grams of γ-aminopropyltriethoxysilane, methyl 50 grams of methyl acrylate-butadiene-styrene copolymer and 8 grams of monoglyceride stearate were stirred in a high-speed mixer at 1100 rpm for 5 minutes, and released after being uniform. Put the mixed material into the twin-screw extruder with a length-to-diameter ratio (L / D) of 40. The processing temperature of the twin-screw extruder: the temperature in the first zone is 180°C, the temperature in the second zone is 185°C, and the temperature in the third zone is 180°C. The temperature of the fourth zone is 195°C, the temperature of the fourth zone is 210°C, the temperature of the fifth zone is 215°C, the temperature of the sixth zone is 225°C, the temperature of the seventh zone is 235°C, the temperature of the eighth zone is 240°C, and the speed of the main engine is 320 rpm; After c...

Embodiment 2

[0020] A heat-resistant modified plastic was prepared in the same manner as in Example 1, except that decabromodiphenyl ether was not used.

Embodiment 3

[0022] A heat-resistant modified plastic was prepared in the same manner as in Example 1, except that N-phenylmaleimide was not used.

Abstract

The invention relates to a heat-resistant modified plastic which comprises the following components in parts by weight: 40-70 parts of ABS (acrylonitrile-butadiene-styrene), 3-8 parts of interfacial coupling agent, 3-10 parts of toughener, 0.5-1.0 part of dispersing and lubricating agent, 5-10 parts of decabromodiphenyl oxide and 10-15 parts of N-phenylmaleimide. The heat-resistant modified plastic provided by the invention has excellent heat resistance, can be widely used in automobile industry, and is often used for manufacturing daily necessities, such as automobile parts, home appliance industry, architectural decoration industry, crash helmets, motorcycle fenders, heelpieces, snowfield sporting goods, toys, clocks, loudspeaker shells, suitcases, buttons, cosmetic cases and the like, and advertising products of nameplates, ornaments and the like.

Description

technical field [0001] The invention relates to the field of plastics, in particular, the invention relates to a heat-resistant modified plastic. Background technique [0002] ABS (acrylonitrile-butadiene-styrene) resin is an important general-purpose synthetic resin. The main body is a blend or terpolymer of acrylonitrile, butadiene and styrene. It is a tough and rigid thermoplastic. plastic. It has a wide range of uses. The automobile industry is often used to manufacture auto parts such as instrument panels, body panels, interior trim panels, steering wheels, sound insulation panels, door locks, bumpers, ventilation pipes, etc. The home appliance industry is often used to manufacture such as refrigerators, TVs, etc. Machines, washing machines, vacuum cleaners, food mixers, telephone casings, etc., are commonly used in the construction and decoration industry to manufacture sanitary ware, swimming pool linings, pipes and pipe fittings, etc., and are also used to manufactu...
