Abstract

The invention provides a material for preparing a military box set. The material is obtained through modification of high density polyethylene by means of linear low density polyethylene, low density polyethylene, ethylene-ethylic acid ethylene copolymer and nano calcium carbonate. Preferably, 83-87 parts by weight of high density polyethylene, 4-8 parts by weight of linear low density polyethylene, 4-8 parts by weight of low density polyethylene, 1-3 parts by weight of ethylene-ethylic acid ethylene copolymer and 0.5-1 part by weight of nano calcium carbonate are adopted. The grain size of nano calcium carbonate is smaller than or equal to 100 nm. Specifically, the material is prepared in the way that mixing is conducted before grinding or grinding is conducted before mixing, then heating melting is conducted, and finally temperature is reduced to indoor temperature. A relevant preparing process and application are further provided. The material is unique and ingenious in design, easy to prepare and operate, higher in shearing strength with polyurethane, firm and durable and high in heat insulation performance, and a military box made of the material is firm and durable, high in heat insulation performance and suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of packaging products, in particular to the technical field of military case sets, in particular to a material for preparing military case sets and a preparation method thereof. Background technique [0002] "Soldiers and horses are not moved, food and grass go first." This ancient saying is a summary of the experience of previous wars. It reflects the special status and role of logistics support in military operations. Xi Jinping, chairman of the Central Military Commission, also proposed "logistics Guarantees should be in line with international standards". As military products have higher and higher requirements for packaging products in the process of transportation and storage, traditional wooden boxes and iron boxes and other packaging products have factors such as poor mobility, inconvenient loading and unloading, not environmentally friendly, poor sturdiness and durability, and poor thermal insulatio...
