Abstract

The invention discloses a high-performance modified PP sheet and a processing technology, and belongs to the technical field of processing and application of novel high polymer materials. The PP sheet comprises carbon fiber reinforced epoxy resin composite material upper skin, carbon fiber reinforced epoxy resin composite material lower skin, a PP honeycomb sheet, a group of epoxy resin foam, a group of epoxy resin foam reinforced brackets, upper epoxy resin adhesive film and lower epoxy resin adhesive film. Each epoxy resin foam reinforced bracket comprises a first reinforcing rod, a second reinforcing rod, a third reinforcing rod, a fourth reinforcing rod, a middle supporting rod and an outer wall. According to the high-performance modified PP sheet, each arranged epoxy resin foam reinforced bracket is formed by folding one steel wire, the outer wall and the reinforcing rods inside are connected end to end one by one, it can be guaranteed that the connecting strength at each folding position is high, and when an enclosure is in use and stressed with force, the high-performance modified PP sheet is not prone to being broken. The processing technology is simple, forming is rapid to carry out, the production efficiency is improved, the production cost is reduced, and therefore the requirement for industrial application in the industrial field is met.

Description

technical field [0001] The invention belongs to the technical field of novel processing and application of polymer materials, and in particular relates to a high-performance modified PP plate. The invention also relates to a processing technology of high-performance modified PP board. Background technique [0002] PP hollow sheet (polypropylene hollow sheet) is made of polypropylene raw material blended with polyethylene raw material and extruded through a hollow sheet production line. It is widely used in construction industry, advertising industry, agriculture, interior decoration, breeding industry, packaging and transportation industry, etc. field. [0003] When used in the packaging and transportation industry, the traditional PP hollow boards are generally connected with vertical corrugated ribs between the double-layer PP boards. The overall strength of this structure is small, and its force can only be in the vertical direction. During packaging and transportation,...
