Embodiment Construction

[0019] (1) Extrusion molding process

[0020] The matrix material 1 of the longitudinally reinforced polymer profile adopts extruded polyurethane (TPU), polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), etc. and between them or between rubber and plastic elastomers The blended modified material, and the steel wire, steel strand, steel wire rope, fiber and fiber rope and other linear reinforcement materials 2 whose surface has been treated by degreasing, rust removal, activation and other processes, are processed by extrusion molding . The forming section of the extrusion die is made according to the needs image 3 As shown in various cross-sectional shapes or other shapes, the extrusion die mouth is provided with reinforcing material 2 positioning outlet holes, and the reinforcing material 2 is co-extruded synchronously while extruding the base material 1 . The leading-out direction of the reinforcing material is the molding direction of the profile, which for...

Abstract

A longitudinally reinforced high-molecular section features that the linear reinforcing material (steel wire, twisted steel wires, steel cable, fibre, or fibre strings) are longitudinally contained in the high-molecular section. Its preparing process may be one of extruding out, injection, die pressing, casting and pressing.

Description

1. Technical field [0001] The invention relates to the field of polymer profiles, in particular to a longitudinally reinforced polymer profile. 2. Background technology [0002] In highway guardrails, highway and park guardrails, conveyor belt rollers and brackets, light poles and other main material structures, the maximum stress is along the longitudinal or length direction of the structure. At present, the materials used in these structures are mostly metal profiles, pipes or plates. Although polymer materials such as plastics are occasionally used, they cannot achieve the intended purpose due to their poor elasticity and low strength. Although the metal material has high strength, it is easy to rust in the natural environment, it is difficult to restore the original shape after being deformed by the impact load, and the price is high (especially stainless steel). [0003] At present, the existing polymer profiles, such as various fiber-reinforced plastic shell materials...
