Abstract

The invention discloses a high-transparency and lightweight polypropylene composite material, which comprises the following ingredients in parts by weight: 50-90 parts of PP resin, 4-35 parts of toughening agent, 4-30 parts of filler and 0.2-4 parts of auxiliary agent The PP resin is a PP rigid resin, the PP resin is a PP resin with a light transmittance of not less than 55% for a 2mm square plate, and the weight of the two-dimensional filler in the filler is low in the polypropylene composite material in 10 servings. The present invention realizes the high light transmittance and the balance of rigidity and toughness of the resin system by selecting high light transmittance PP, high rigidity PP matrix and styrene elastomer with similar refractive index to PP; the present invention also discloses a high light transmittance 1. Preparation method of lightweight polypropylene composite material.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a high light-transmitting, lightweight polypropylene composite material and a preparation method thereof. Background technique [0002] As a cost-effective general-purpose plastic, polypropylene (PP) has excellent mechanical properties after toughening and modification, and is easy to form and process. It is widely used in home appliances and automotive products. [0003] With the development of Internet technology and electronic technology, interior and exterior surfaces have become decorative surfaces with a sense of design, integrating decoration and functionality, which puts forward new requirements for light transmission of automotive materials. Polycarbonate (PC) and polymethyl methacrylate (PMMA) are two traditional transparent polymer materials. However, the fluidity of PC is poor, and it is difficult to inject large parts. The toughness of PMMA is poor, and ...
