Stinging two-way stretching plastic protective screen and manufacturing method thereof

Abstract

The invention discloses a stinging two-way stretching plastic protective screen and a manufacturing method thereof. A grating is an integrally formed net-shaped structure, the net-shaped structure comprises a plurality of longitudinal ribs and a plurality of transverse ribs, the longitudinal ribs and the transverse ribs are arrayed alternatively, joints are formed at intersected positions of the longitudinal ribs and the transverse ribs, two short ribs are arranged at each joint, and an included angle between each short rib and the corresponding longitudinal rib and an included angle between each short rib and the corresponding transverse rib are 45 degrees. The stinging two-way stretching plastic protective screen has a warning function, has excellent integral rigidity, and is an excellent safety protection material.

Description

technical field [0001] The present invention relates to a building material. Background technique [0002] At present, the plastic protective net is mainly used for protection and isolation in construction projects, especially the thorny plastic protective net can effectively prevent the invasion of animals, and can also be used as protection for courtyards, pastures, forest farms, etc., and has a good isolation effect and visual deterrent. [0003] There are a variety of production methods for plastic tensile mesh structure materials. Some use plastic strips to be welded into well-shaped or square or rectangular structures, and some use molten plastic rotating heads to extrude mesh materials, and then perform one-way or two-way stretching. Some use molten plastic to form mesh materials on the reciprocating machine head, and then stretch them in one or two directions. These materials play a certain protective role to varying degrees, but due to poor overall rigidity, mainly...

Problems solved by technology

[0003] There are a variety of production methods for plastic tensile mesh structure materials. Some use plastic strips to be welded into well-shaped or square or rectangular structures, and some use molten plastic rotating heads to extrude mesh materials, and then perform one-way or two-way stretching. Some use molten plastic to form mesh materials on the reciprocating machine head, and then stretch them in one or two directions. These materials play a certain protective role to varying degrees, but due to poor overall rigidity, mainly Can serve as a warning

[0004] However, in practical applications, it is found that such materials can only play a warning role, and have almost no effect on large animals, especially for theft or vandalism.
