Embodiment Construction

[0012] As shown in the figure, an aramid powder composite injection molded crawler core includes an aramid skeleton and a shell. The shell is an outer shell made of ultra-high molecular weight polyethylene, and the outer shell made of ultra-high molecular weight polyethylene is covered on the surface of the aramid skeleton.

[0013] The production process of the above-mentioned aramid powder composite injection molding crawler core gold, firstly, the aramid powder is processed by glue coating and static removal process, and then pressed at a high temperature of 130°C~180°C and a pressure environment of 10MPa~16MPa to form an aramid fiber skeleton, and then Under the pressure of 120℃~150℃ and 9MPa~12MPa, the ultra-high molecular weight polyethylene is coated on the surface of the aramid fiber skeleton, so that the ultrahigh molecular weight polyethylene and the internal aramid fiber powder are integrated.

[0014] In the present invention, the aramid fiber material is used as a ...

Abstract

The invention discloses aramid powder composite injection molded caterpillar core gold and a production process thereof. The core gold comprises an aramid framework and a shell, wherein the shell is an ultrahigh molecular weight polyethylene material shell; the ultrahigh molecular weight polyethylene material shell wraps the surface of the aramid framework; firstly, aramid powder is glued and is treated by an anti-static device, the aramid powder is pressed through high temperature and high pressure to form the aramid framework, and then the ultrahigh molecular weight polyethylene wraps the surface of the aramid framework, so that the ultrahigh molecular weight polyethylene and the internal aramid powder are integrally fused. The aramid material is used as the framework material to be used in the caterpillar core gold, and the strength and the service life of the caterpillar core gold are greatly improved and prolonged; detection proves that the caterpillar core gold has the advantages that the strength is doubled and the life is prolonged for three times compared with the normal caterpillar core gold.

Description

technical field [0001] The invention relates to the technical field of polymer composite profiles, in particular to an aramid powder composite injection molded track core gold and a production process thereof. Background technique [0002] Rubber track is a walking part, because it has a large ground contact surface, has the advantages of anti-slip, anti-sinking, and little damage to the road surface, so it is widely used in construction machinery such as ATVs, snowmobiles, and all-terrain vehicles, as well as agricultural machinery. field. The rubber track is mainly composed of core metal, connecting pins and rubber body. At present, the core metal of rubber track is mostly made of steel casting or composite material. The current steel casting material or composite material core gold is not strong enough, and it is easy to deform, resulting in plastic steel. The service life of profile products is short, which affects the use effect of plastic steel profiles. [0003] The...
