Title:
RUBBER-TOUGHENED POLYPROPYLENE COMPOSITE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/133603
Kind Code:
A1
Abstract:
Disclosed are a rubber-toughened polypropylene composite and the use thereof. The composite comprises the following components: 45 parts - 69 parts of polypropylene; 15 parts - 25 parts of talc powder; 15 parts - 25 parts of an elastomer; and 1 part - 5 parts of a lubricant, wherein the lubricant is a compound of an internal lubricant and an external lubricant; and the mass ratio of the internal lubricant to the external lubricant is 1 : 4 to 4 : 1. In the present invention, the compound of an internal lubricant and an external lubricant is used in the polypropylene/talc powder/elastomer formulation system, and the compound proportion of the two is controlled to be within a certain range, such that the surface tension of the elastomer and the polypropylene is decreased during blending so as to effectively reduce the average particle size of the elastomer in a polypropylene matrix and promote the good dispersion of the elastomer in the polypropylene matrix, thereby greatly improving the rigidity of the material while ensuring that the material has excellent normal-temperature and low-temperature impact properties, avoiding the problem of a significant decrease in the rigidity of the material, and meeting the need for the development of automobile interior decorating materials.
