Embodiment 1

[0014] Weigh 600 grams of ABS and dry it at 90°C for 4 hours, then mix with 80 grams of silica, 130 grams of glass fiber, 50 grams of γ-aminopropyltriethoxysilane, methyl methacrylate-butadiene- 50 grams of styrene copolymer and 8 grams of monoglyceride stearate were stirred for 5 minutes at 1100 rpm in a high-speed mixer, and released after being uniform. Put the material mixed evenly 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 of the first zone is 180°C, the temperature of the second zone is 185°C, and the temperature of the third zone is 180°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; Afterwards, the stretcher is cooled, air-dried and pelletized, and ...

Embodiment 2

[0016] A high-strength plastic was prepared in the same manner as in Example 1, except that silica was not used.

Embodiment 3

[0018] A high-strength plastic was prepared in the same manner as in Example 1, except that glass fibers were not used.

Abstract

The invention relates to a high-strength 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 silicon dioxide and 10-15 parts of glass fiber. The high-strength plastic provided by the invention has excellent strength, 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 high-strength 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 manufacture safety ...
