Problems solved by technology

However, as an inorganic filler, ceramics are much harder than polypropylene. Although it can reduce the friction damage caused by other surfaces to the surface of the BOPP film, the BOPP film itself will also rub during the winding process, which increases the friction between the films. The degree of grinding is not worth the candle

Abstract

The invention belongs to the technical field of plastics, and discloses a wear-resistant master batch as well as a preparation method and application thereof. The melt index of the master batch under 2.16 kg and 230 DEG C is 10-14 g / 10 min. The master batch is prepared from the following raw material components: a carrier, single-terminal carboxyl polyolefin wax, double-terminal hydroxyl polysiloxane and an organic spherical anti-sticking agent. According to the master batch, double-terminal hydroxyl polysiloxane is modified by using single-terminal carboxyl polyolefin wax to form a block copolymer, so that the compatibility and the dispersing performance of the double-terminal hydroxyl polysiloxane in ternary copolymerized polypropylene serving as a carrier are improved, and when the master batch is used for forming a film layer on the surface of a BOPP (Biaxially-Oriented Polypropylene) thin film, the film layer is not prone to falling off. According to the present invention, the prepared BOPP film has characteristics of uniform smoothness and precipitate reduction, can form the cross-linked netted elastomer at the normal temperature, and has characteristics of good collision resistance and good impact resistance, such that the wear resistance and the scratch resistance of the BOPP film can be substantially improved, and the light transmission of the BOPP film cannot be reduced.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a wear-resistant masterbatch and its preparation method and application. Background technique [0002] Plastic film is easy to use and is widely used in the packaging of daily items. Some of them have excellent transparency and can display the contents of the package, which is very popular among consumers. For the cigarette field, highly transparent BOPP film is generally used at present (BOPP film is a melt of high molecular weight polypropylene, which is first made into a sheet or thick film through a narrow and long die, and then in a special stretching machine, at a certain temperature and Stretching in two vertical directions (longitudinal and transverse) simultaneously or step by step at a set speed, and then packaged with appropriate cooling or heat treatment or a film made by special processing, the effect of blocking water Excellent, beautiful and practical...
