Problems solved by technology

The polypropylene honeycomb core has a certain structural rigidity and light weight per square meter. However, the polypropylene honeycomb core is a honeycomb sheet, and the ductility of the material in the plane direction is poor. It is difficult to press into a special-shaped shell material by conventional hot pressing technology. Honeycomb core cracks, surface folds, local fractures, shape defects, bubbling, distortion, etc. will occur, and it cannot be made into a suitcase shell material that meets the requirements

Embodiment 1

[0029] A preparation method for a suitcase case material, comprising the steps of:

[0030] 1) Choose a thickness of 6-10mm and a density of 60-120kg / m 3 The polypropylene honeycomb core is used as the skeleton, such as figure 1 As shown, the preparation method of the polypropylene honeycomb core material refers to the patent document with the publication number CN102689458A, that is, the polypropylene honeycomb core is: a plurality of double-layer composite pipes are spliced ​​into a honeycomb shape, and the adjacent double-layer composite pipes are closely attached. The outer layers of the polypropylene honeycomb core are bonded together, and the end faces of the inner layers of the adjacent double-layer composite pipes are fused to form glue bumps; the upper and lower sides of the polypropylene honeycomb core respectively refer to the two ends of the multiple double-layer composite pipes. surface; use a melting point higher than 200 ° C, heat shrinkage rate of 4% to 8% at ...

Abstract

The invention discloses a travelling case shell material and its preparation method. According to the preparation method, a bonding layer is additionally arranged between the surface layer of a composite honeycomb plate and a honeycomb core, a pre-pressing die-forming die cooperated hot press molding means is adopted, comprehensive analysis and creative matching are carried out through the joint action and mutual influence of material, thickness, density, melting point, heat shrinkage and other material performance parameters and hot pressing technological parameters, so that preparation of a special shaped honeycomb board can be realized, and the problems of honeycomb core breaking, surface layer folding, local fracture, surface defect, distortion and the like existing in the prior art can be avoided. The travelling case shell material prepared according to the technical scheme involved in the invention has the advantages of high performance price ratio, good rigidity, light weight, environmental protection, and good shock resistance.

Description

technical field [0001] The invention belongs to the field of bags, and in particular relates to a travel case shell material and a preparation method thereof. Background technique [0002] Luggage is an essential daily necessities for people, and people are constantly developing and experimenting with various materials to make luggage. Lightweight luggage is the focus of the current new luggage reform. Lightweight bags can make people travel more convenient and comfortable, can improve people's lives, reduce the fatigue of the journey, can easily carry more items, and increase the convenience of the journey. However, there are not many materials that can really be used to make lightweight luggage shells. Plastic is a material with high specific strength and good formability. People usually choose a large number of thermoplastic materials to make bags, such as EVA, ABS, PC and so on. EVA material is flexible, but not rigid enough. In the process of making luggage, skeleton...
