preparation example Construction

[0018] A kind of preparation method of PP toughening modified material, it mainly comprises the steps:

[0019] (1) Batching: batching raw materials according to the above mass ratio;

[0020] (2) Mixing: Stir the raw materials prepared in step (1) in a high-speed mixer for 10 minutes;

[0021] (3) Extrusion: Add the mixed material mixed in step (2) into a twin-screw extruder for blending, cooling, and pelletizing to obtain modified material A;

[0022] (4) Drying: Dry modified material A in a drying box to obtain modified material B;

[0023] (5) Injection molding: Injection molding the modified material B on an injection molding machine.

[0024] In order to further optimize the technical solution, the notched impact energy of the PP toughened modified material can reach 15.3KJ / m2, the tensile strength can reach 42.5Mpa, the bending strength can reach 32.1Mpa, and the elongation at break can reach 248%.

Embodiment 1

Abstract

The invention discloses a PP toughening modified material and a preparation method thereof, and belongs to the technical field of new materials. The PP toughening modified material comprises the following main components by mass: 70-74 parts of PP-9928 raw materials, 3-5 parts of a coupling agent, 1-3 parts of EBS, 2-5 parts of PE wax and 5-10 parts of POE. The PP toughening modified material hasthe advantages that the process is simple, easy to control, and suitable for mass production, and solves the problems that when used in the case of-10 DEG C to 23 DEG C the existing PP has poor resistance to low temperature and large breakage rate which greatly limit industrial application, and the like, and the PP toughening modified material has high whiteness, low temperature resistance, strongdrop resistance, and bending and compression resistance.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a PP toughening modified material and a preparation method thereof. Background technique [0002] Polypropylene PP has low density, strength, stiffness, hardness and heat resistance are superior to low-pressure polyethylene, can be used at about 100 degrees, has good electrical properties and high-frequency insulation is not affected by humidity, but becomes brittle at low temperatures , not wear-resistant and easy to age, thus greatly limiting its application fields. Contents of the invention [0003] The purpose of the present invention is to provide a PP toughened modified material, which is mainly used to solve the above problems. [0004] The present invention solves technical problem and adopts following technical scheme: [0005] Provide a PP toughening modified material, its main composition and mass ratio are: 70-74 parts of PP-9928 raw material, 3-5 parts of c...
