Abstract

The invention relates to a high-performance PP-PS composite material. The high-performance PP-PS composite material is prepared from the following components in parts by weight: 30-50 parts of PP, 40-60 parts of PS, 3-5 parts of HDPE, 8-12 parts of treated titanium dioxide, 0.1-0.5 part of an antioxidant, 0.4-0.8 part of a lubricant and 0.1-0.5 part of a compatibilizer, and the treated titanium dioxide is titanium dioxide treated with toluene diisocyanate. According to the high-performance PP-PS composite material, TDI chemically reacts with -OH on the surface of nano TiO2 to increase barriersbetween TiO2 and inhibit the agglomeration phenomenon caused by the collision of TiO2 to some extent, so that the compatibility with organic matter is effectively improved, the agglomeration of TiO2is prevented, and the physical properties of the high-performance PP-PS composite material is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a high-performance PP-PS composite material. Background technique [0002] Polypropylene (PP) is an important thermoplastic polymer. It has low density, low water absorption, oil and chemical resistance, and outstanding stress crack resistance. It has become one of the most widely used plastics in modern times. Polystyrene (PS) has good comprehensive properties, such as excellent thermodynamic properties, good toughness, good chemical resistance, good wear resistance, self-lubrication and excellent electrical insulation. [0003] In recent years, researches on blending polypropylene and polystyrene to prepare alloys are not uncommon. Composite materials prepared from polypropylene and polystyrene are now widely used in the fields of packaging materials, toys, electrical appliances and household appliances. Safety in the process. In the above-mentioned fields, when usin...
