Problems solved by technology

However, the hollow panels in the prior art have a single type. Although the overall strength in one direction is high, the relative strength in the vertical direction is poor, and it is difficult to overlap itself or cooperate with other profiles.
[0003] Continuous fiber thermoplastic reinforced sheets are widely used because of their good mechanical properties, but due to their high cost, they cannot be widely promoted

Embodiment 1

[0038] A continuous glass fiber reinforced polypropylene hollow board, the structure of which is as follows figure 1 shown. In this example, continuous glass fiber reinforced polypropylene is selected as raw material, 50 parts of polypropylene, 3 parts of grafting agent, and 0.5 parts of antioxidant are added to the extruder, and after stretching the fibers at the die head and through multiple mechanical rollers 50 parts of continuous glass fiber bundles are infiltrated and compounded, and then roll-formed to make a prepreg tape by roller winding and curling.

[0039] The specifications for making hollow boards are 2000mm*1500mm*10mm, and the preparation method is as follows:

[0040] (1) Cut the strip-shaped prepreg tape, and lay it in the direction of 0° / 90° according to the direction of the continuous fiber in the prepreg tape, and the laying thickness is 5mm;

[0041] (2) Evenly insert a 5mm diameter steel cylindrical core material sprayed with polytetrafluoroethylene in...

Abstract

The invention relates to a hollow plate and a manufacturing method thereof. The hollow plate is manufactured from the following components by weight: 40-50 parts of thermoplastic resin, 50-60 parts of a continuous fiber bundle, 1-5 parts of a grafting agent, and 0.4-0.6 part of an antioxidant. The manufacturing method includes: adopting a lamination process to lay a strip prepreg made from continuous fiber reinforced thermoplastic resin according to a mode of 0 degree-90 degrees, and placing the strip prepreg in a mold to conduct thermal forming, thus obtaining the hollow plate. By changing the hollow position and increasing the plate height, the plate strength can be enhanced, the sheet weight is reduced, and the cost is lowered. With the characteristics of high strength, high modulus, corrosion resistance, good water resistance, no conductivity and the like, the hollow plate is convenient to process and easy to clean, and has short forming cycle. The waste materials in production and the final product can all realize 100% recovery. Thus, the method belongs to a ''green'' product technology.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a hollow board made of continuous fiber reinforced resin prepreg and a manufacturing method thereof. Background technique [0002] At present, hollow board, as an environmentally friendly plastic board, is widely used in related fields such as construction industry, advertising industry, agriculture, indoor breeding industry and packaging industry. At present, most hollow boards are made of PP, PC, PE, PVC, ABS and other related plastics as raw materials, and are processed through a one-time extrusion process. It includes a panel, a frame and equidistant plates connected between the two, and has the characteristics of light weight, beautiful appearance, non-toxicity, anti-corrosion and flame retardancy, and has a certain effect of heat preservation and heat insulation. However, the hollow boards in the prior art have a single shape. Although the overall str...
