Embodiment 1

[0023] Embodiment 1: (taking the back shell of a 25-inch TV as an example)

[0024] Choose an injection molding machine with a screw diameter of 90 mm, an inner diameter of the nozzle (nozzle) of 6 mm, a mold runner diameter of 10 mm, and a gate area of ​​20 mm 2 processing equipment. And adjust the screw back pressure to 2 kg / mm 2

[0025] The polypropylene plastic with a glass fiber weight content of 15% is selected for use, and the average length of the glass fiber is 12 mm. The rear shell of the TV is manufactured by injection molding process, and its wall thickness is 3mm.

[0026] Drop test: pass the drop test of the whole machine in GB8898 national standard

Embodiment 2

[0028] Adopt exactly the same equipment and processing conditions as in Example 1, still use glass fiber weight content 15%, but short glass fiber reinforced polypropylene (PP) with an average length of 0.6mm. If it fails the above drop test at all.

Embodiment 3

[0030] The polypropylene plastic with a glass fiber weight content of 20% is selected, the average length of the glass fiber is 55mm, and the processing equipment and technology are exactly the same as those in Example 1. However, the nozzle (nozzle) was clogged during the injection molding process, and the product could not be obtained at all.

Abstract

An ordinary-pressure load-bearing container is fully or partly prepared from the fiber-reinforced polymer. The said fiber has the 1-30 mm in average length and weight ratio of 5-55%. Its advantages are high weight and high compression strength, impact strength and corrosion resistance. The process and apparatus for preparing said fiber reinforced polymer are also disclosed.

Description

technical field [0001] The invention relates to a novel normal-pressure bearing container, a processing method and equipment for its component fiber-reinforced thermoplastic polymer. Background technique [0002] Fabrication of fiber-reinforced composite materials by lamination, wrapping, and filament winding of thermosetting resins and / or thermoplastic resins with fibers is well known. [0003] In the Chinese patent No. ZL00803968.2, titled "Fiberglass Reinforced Plastic Cylinder and Its Manufacturing Method", it is described that the reinforced fiber base material is prepared in the core body by using fiber unidirectional materials, fabrics, mats, braided ropes, etc. inside and outside. Publication No. is the invention patent of CN1427036A and has introduced the manufacturing method of the box body of the electronic power distribution equipment that is coated on fiber cloth both sides with polyester resin. In the invention patent of ZL97107010.5, the fiber box body is ma...
