Problems solved by technology

In order to improve the sealing performance of the luggage, the material of the side strip is mainly a flexible material. However, the material with good flexibility is often easy to be cut by foreign objects, especially when the luggage is closed repeatedly for a long time and it is easy to be cut during transportation. Side strips are more prone to cuts and cuts
The edge strips with better hardness have better cut resistance, but the tightness of the press is not flexible.

Abstract

The invention relates to the technical field of suitcases, in particular to a super-tough and cut-resistant suitcase edging composite material and a preparation method thereof. The super-tough and cut-resistant suitcase edging composite material comprises: 50-65% of PVC resin, 7-12% of nano-calcium carbonate, 12-18% of dioctyl terephthalate, 7-12% of polyamide, 1-2.5% of a stabilizer, 0.1-0.5% ofa toughening agent, and 2-6% of soybean oil. The suitcase edging composite material provided by the invention has both toughness and cut resistance, thus improving the sealing performance and durability of suitcase edgings. The preparation method includes pretreatment and melt granulation. The preparation method can prepare the super-tough and cut-resistant suitcase edging composite material.

Description

technical field [0001] The invention relates to the technical field of luggage, in particular to an ultra-fine, tough and cut-resistant luggage edge composite material and a preparation method thereof. Background technique [0002] Luggage bags have become one of the necessary daily necessities for people. Today's luggage is mostly composed of upper and lower hard case covers, and the lids of the upper and lower hard case cases need to be provided with a case edge respectively. strips to improve the seal of the lid closure. In order to improve the sealing performance of the luggage, the material of the side strip is mainly a flexible material. However, the material with good flexibility is often easy to be cut by foreign objects, especially when the luggage is closed repeatedly for a long time and it is easy to be cut during transportation. Edge strips are more prone to cuts and cuts. The edge strips with better hardness have better cut resistance, but the tightness of the...
