Embodiment 1

[0056] Add copolymerized polypropylene, elastomer, linear low-density polyethylene, grafted polyethylene, stabilizers (including Irganox 1010 and Irganox 168) and processing aids into the high-speed mixing pot according to the amount shown in Table 6, stir and mix evenly. The mixed material is obtained, in which the source and performance of the raw materials are shown in Table 1. The mixture material is fed into the twin-screw extruder from the feeder, and the residence time of the material in the screw is 50 seconds to 120 seconds. The temperature of the twin-screw extruder from the feeding section to the head is: 180℃, 215℃ , 215℃, 215℃, 215℃, 215℃, 215℃, the temperature of the die is 220℃. After high-speed twin-screw (screw speed of 600r / min) shearing, mixing, extrusion, drawing, air cooling, drying, pelletizing and packaging by the head, the low-temperature resistant copolymer polypropylene modified material is prepared.

Abstract

The invention discloses a low-temperature resisting co-polypropylene modified material as well as a preparation method and an application thereof. The low-temperature resisting co-polypropylene modified material comprises the following raw materials in percentage by weight: 60-98% of co-polypropylene, 1-20% of an elastomer, 0-10% of linear low-density polyethylene, 0-8% of stem grafting polyethylene, 0.1-1% of a stabilizer and 0.1-1% of a processing agent. The modified material has both good tension strength and high-temperature property and good low-temperature property, the performances of a conventional polypropylene plastic sealing stripe are improved, the requirements on use of the plastic sealing stripe at high and low temperatures are met, and the modified material can be used for preparing various plastic sealing stripes, such as air container sealing stripes, cultivation sealing stripes, self-locking type sealing stripes and anti-theft sealing stripes.

Description

Technical field [0001] The invention relates to a polypropylene modified material in the field of polymer materials, in particular to a low-temperature resistant copolymerized polypropylene modified material, and a preparation method and application thereof. Background technique [0002] A plastic seal is an accessory made of plastic. It consists of two parts. One end is a round or square plastic mouth with a hook-shaped elastic plastic buckle, and the other end is a plastic seal body with serrations. The body can be bent through the front plastic opening and form a loop, similar to the belt of pants, which can be used for binding and packaging; plastic seals are usually made by one injection molding process, which can be made into yellow, blue, white, green, orange, and red And other bright colors. Since the serrations on the seal strip can be tightly fitted with the elastic plastic buckle inside the plastic mouth, the plastic seal can play a very firm role in fixing. It is no...
