Problems solved by technology

[0003] With the development of society, people have put forward higher requirements for the performance of container bags. The corrosion resistance of container bags in the prior art can no longer meet the requirements of society. After a period of use, corrosion of woven bags will occur. Damage phenomenon, there is a defect of short service life, which limits its application range

Embodiment 1

[0032] A corrosion-resistant container bag is made from the following components by weight:

[0033]

[0034] The wear-resistant agent is composed of glass fiber powder and nano carbon black, and the ratio of the glass fiber powder and the nano carbon black is 2:1.

[0035] The preparation process of the above-mentioned container bag comprises the following steps:

[0036] (1) Put polypropylene, polyvinyl chloride, anti-wear agent, sulfur antioxidant, ultraviolet light absorber and porous carrier into a high-speed mixer, and heat, melt and mix at 180°C and 1200 rpm;

[0037] (2) the melt obtained in step (1) is added to the extruder with a feed rate of 120kg / min, the extruder rotational speed is set to 600 rev / min, and the extrusion time is 15 minutes, extruded into a liquid film, and immediately enters the water Cooling and shaping, it becomes a solid film;

[0038] (3) the solid film obtained in step (2) is drawn to the knife holder with a pulling roller, cut into embry...

Abstract

The invention discloses a corrosion-resistant container bag and a preparation process thereof. Relates to the technical field of container bags. The problem that a container bag in the prior art is insufficient in acid and alkali resistance is solved. The container bag is prepared from the following components in parts by weight: 95-105 parts of polypropylene; 10 to 20 parts of polyvinyl chloride; 1-2 parts of a wear-resistant agent; 0.2 to 0.4 part of a sulfur antioxidant; 0.5-1 part of an ultraviolet light absorber; 1-2 parts of a porous carrier; the wear-resistant agent is composed of glass fiber powder and nano carbon black; the flexible freight bag has excellent acid and alkali resistance, the service life of the flexible freight bag is prolonged, and the application range is widened.

Description

technical field [0001] The invention belongs to the technical field of container bags, and particularly relates to a corrosion-resistant container bag and a preparation process thereof. Background technique [0002] The container bag is mainly made of polypropylene (PP) and other resins with a small amount of auxiliary materials added and mixed by an extruder. The plastic film is extruded and cut into filaments. It is stretched at a temperature lower than the melting temperature of the resin. It is made of high-strength, low-elongation flat yarn, and then rolled, woven, cut, and sewed into a plastic woven bag. At present, container bags have been widely used in agricultural product packaging, construction packaging, chemical product packaging, food packaging and other fields. [0003] With the development of society, people have put forward higher requirements for the performance of container bags. The corrosion resistance of container bags in the existing technology can no...
