Abstract

The invention discloses a polyester fiber reinforced PVC (polyvinyl chloride) composite material with an intermediate foaming layer and a preparation method of the material. The composite material sequentially comprises a PVC surface film layer, a PVC paste layer, a PVC micro-foaming paste layer, a polyester fiber screen-cloth base material, a PVC micro-foaming paste layer, a PVC paste layer and a PVC bottom film layer from top to bottom. The polyester fiber reinforced PVC composite material with the intermediate foaming layer has the characteristics of light weight, softness in hand-touching, bending resistance, good low-temperature bending resistance, heat insulation, shock absorption and the like and also has the advantages of environmental friendliness, precipitation duration and the like.

Description

technical field [0001] The invention belongs to the field of polymer material preparation, and relates to a polyester fiber reinforced PVC composite material, in particular to a polyester fiber reinforced PVC composite material with a foaming layer in the middle and a preparation method thereof. Background technique [0002] Polyester fiber reinforced PVC composite material has the characteristics of good air tightness, high strength, light weight, good flexibility and excellent welding performance. Therefore, it is widely used in membrane structure materials, canopy materials, inflatable boat materials, inflatable materials and other fields. However, for applications that require high folding resistance, especially low-temperature bending properties, simply by increasing the content of plasticizers in the PVC paste and PVC film formulations, better flexibility and hand feel can be obtained, and material deformation can be avoided. Hard, the effect is limited, and it will i...
