Embodiment 1

[0026] 100 parts by weight of homopolypropylene (F401, produced by Yangzi Petrochemical Co., Ltd.), 0.65 parts by weight of di-tert-butyl peroxide (DTBP, produced by Tianjin Lisheng Chemical Co., Ltd.) were placed in a high-speed mixer and stirred evenly with A twin-screw extruder (TE35 type, Nanjing Keya Technology Development Co., Ltd.) extruded and granulated peroxide masterbatch at a temperature not higher than 190°C for later use.

[0027] With 100 parts by weight of random copolymerized polypropylene (self-made), 0.10 parts by weight of phenolic antioxidant β-(4-hydroxyl-3,5-di-tert-butylphenyl) n-octadecyl propionate ( Product number: 1076, Ciba Specialty Chemicals), 0.10 parts by weight of tris (2.4-di-tert-butylphenyl) phosphite, 0.10 parts by weight of halogen absorbent (high-purity calcium stearate, Shanghai Fuhua Industrial Co., Ltd. company), 2 parts by weight of organomodified silicone (BASF IRGASURF SR100) and 5 parts by weight of ethylene-α-octene copolymer ela...

Embodiment 2

[0031] Basically the same as Example 1, but with the following changes:

[0032] The amount of Engage 8130 added was changed to 10 parts.

[0033] The obtained scratch-resistant high-impact polypropylene composition is denoted as NPO-2. The performance test results are shown in Table 1.

Embodiment 3

[0035] Basically the same as Example 1, but with the following changes:

[0036] The addition amount of organically modified silicone additives was changed to 2.5 parts by weight, and the feeding mass rate ratio of the main feeding port and the auxiliary feeding port was controlled to be 100:5.

[0037] The obtained scratch-resistant high-impact polypropylene composition is denoted as NPO-3. The performance test results are shown in Table 1.

Abstract

The invention discloses a scratch-resistant high-impact random co-polypropylene and a preparation method thereof. The scratch-resistant high-impact random co-polypropylene is prepared from the following raw material components in parts by weight: 100 parts of a co-polypropylene base material, 0-0.1 part of an antioxidant, 0-0.1 part of a halogen absorbent, 1-3 parts of organic modified silicone, 5-15 parts of a flexibilizer and 1-10 parts of peroxide masterbatch. The special transparent polypropylene material has prominent scratch resistance and toughness; the melt flow rate of the material can be flexibly adjusted; and different processing characteristics can be obtained.

Description

technical field [0001] The invention relates to a scratch-resistant high-impact random copolymerized polypropylene and a preparation method thereof, belonging to the technical field of polypropylene. Background technique [0002] In recent years, with the continuous deepening of reform and opening up and the improvement of people's material and cultural living standards, the demand for high-transparency polypropylene special materials in the domestic market has grown rapidly, and the application fields have become more and more extensive. Higher and higher requirements are put forward for the impact resistance, transparency and scratch resistance of materials, especially in the technical fields of food containers, household appliances, thin-walled and large or complex parts injection molding production. [0003] At present, although there are many reports on the research and development of random copolymerized polypropylene resin materials in China, they are basically limite...
