Problems solved by technology

Among them, the secondary thermal processing that is common in the decoration industry limits the scope of use of polypropylene.
Due to its crystallinity, polypropylene has a rapid transition from glass state to molten state, narrow melting range, small high elastic state range, and low melt strength. During secondary processing, it is prone to tensile fracture and uneven stretching. Case

preparation example Construction

[0034] The preparation method of the polypropylene film of Examples 1-5 is as follows: Add random copolymerized polypropylene and TPO materials into a high-speed mixer and stir, then put in antioxidants and fillers, and after stirring evenly, the materials enter the internal mixer , The material is initially melted in the internal mixer and then enters the double-roll mill for refining. After filtering, it enters the calender roll, and calenders to form a film of the required size. The processing temperature of the calendering host is selected at 170-200°C.

Abstract

The invention discloses a polypropylene film which is mainly prepared from the following raw materials in parts by weight: 100 parts of polypropylene random copolymer, 10-40 parts of TPO, 0.2-3 parts of an antioxidant and 0.5-40 parts of filler, wherein the melt flow rate of the polypropylene random copolymer is 1-15g / 10min. According to the polypropylene film, the melting range is widened, secondary processing can be performed, and the conditions of tensile break and tensile non-uniformity are avoided. Moreover, the requirements of double-vacuum plastic molding can be met, and the polypropylene film can be used for secondary processing and molding for preparing decorative materials.

Description

technical field [0001] The invention relates to a polypropylene film and its application, which can be used for secondary vacuum suction molding to prepare decorative materials. Background technique [0002] Among the five general-purpose engineering plastics, polypropylene has a short development history, but it is the one with the fastest development speed, the largest output, the most grades, and the most widely used. Polypropylene has become one of the polymers with the fastest growing demand due to its low price and excellent performance, as well as being an environmentally friendly material. [0003] In today's society, the range of decorative materials is becoming wider and wider, and the demand is also increasing. Polypropylene has gradually entered the sight of the decoration industry. Among them, the secondary thermal processing that is common in the decoration industry limits the scope of use of polypropylene. Due to its crystallinity, polypropylene has a rapid ...
