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 reciprocatin...

Embodiment 1

[0023] Prepare polypropylene sheets; specifically, high-density polypropylene polymers are selected as raw materials, and additives such as carbon black, anti-ultraviolet agents, and antioxidants are added. The polymer is melted at 180-280°C at the outlet, and the sheet blank is extruded through a hanger-type head, cooled by a three-roll calender, calendered and shaped into a sheet, and the excess edge is cut off; the thickness of the sheet is 5mm;

[0024] A punching machine is used to punch holes in the plastic sheet to form a regularly arranged hole array. Wherein, each hole is a cross hole, the diameter of each cross hole is 5mm, and the distance between holes is 10mm;

[0025] The plate is stretched longitudinally and transversely about 6-12 times at equal ratios successively to form a barbed biaxially stretched plastic protective net. Specifically, the above board is preheated to 100°C, and stretched longitudinally. Depending on the material, the stretching ratio is 6-1...

Embodiment 2

[0027] Prepare polyethylene sheet; its thickness is 8mm;

[0028] A regularly arranged hole array is formed on the plastic plate by punching holes. Wherein, each hole is a cross hole, the diameter of each cross hole is 20mm, and the distance between holes is 40mm;

[0029] The plate is stretched longitudinally and transversely by 4-10 times at the same time to form a barbed biaxially stretched plastic protective net. Specifically, the above board is preheated to 80°C, stretched longitudinally and transversely 4-10 times at the same time, and after heat setting, it becomes a barbed biaxially stretched plastic protective net, which is rolled after trimming.

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...
