Abstract

The invention discloses polyethylene and a preparation method thereof. The polyethylene comprises the following components in parts by weight: 20-30 parts of polyethylene, 10-20 parts of an epoxy resin, 8-12 parts of a reinforcing fiber, 1-2 parts of a thickening agent, 1-2 parts of a thermal insulating agent and 1-2 parts of a toughening agent. According to the polyethylene, due to addition of the reinforcing fiber and the thermal insulating agent in the polyethylene, the high temperature resistance of the polyethylene is effectively improved, so that even if the polyethylene which is appliedto food packaging is heated, no harmful substances can be released into foods as the thermal stability of the polyethylene is not damaged, and human health is not damaged by polyethylene packaging.

Description

technical field [0001] The invention belongs to the technical field of polyethylene processing, and in particular relates to a polyethylene and a preparation method thereof. Background technique [0002] Polyethylene is widely used in the production of agricultural, food and industrial packaging films due to its good properties. However, the polyethylene prepared by the traditional preparation method has poor high temperature resistance, and when it is used for food packaging, it is easy to release harmful substances into the food under high temperature conditions, which poses a health hazard. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a safe and hygienic polyethylene that is less likely to cause harm to human health and a preparation method thereof. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a polyethylene and its preparation ...
