Embodiment Construction

[0008] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0009] figure 1 Among them, single steel plate 1 and screw 2 are coated with adhesive 3 on the outer surface of single steel plate 1. The adhesive is polyurethane adhesive A (Lord 231). After natural drying, put the steel plate into In the mold cavity of an ordinary plastic injection machine, TPU359 polyurethane 4 is injected at a temperature of 200°C and combined with the steel plate 1. After cooling for about 5 minutes, the steel-plastic composite is finalized, and various individual steel-plastic composite steel plates are connected by screws. Steel-plastic composite track shoes. The present invention is tested by the plastic station of the Shanghai Chemical Product Quality Supervision and Inspection Center, and the peel strength and Shore hardness all meet the national standards. The specific data are as follows:

Abstract

The present invention relates to creeper tread for heavy duty transportation machinery and aims at solving the problem of creeper tread to damage road surface. One kind of composite creeper tread ofsteel and polyurethane plastic is disclosed, and the single creeper tread part has one layer of polyurethane coated on to the outer surface. The heavy duty transportation machinery with the composite creeper tread of the present invention can contact well with the road surface, and has no damage to the road surface.

Description

technical field [0001] The invention relates to matching track shoes for heavy transport machinery, in particular to a polyurethane steel-plastic composite track shoe and its processing technology. Background technique [0002] Currently, track shoes for heavy transport machinery, construction machinery, agricultural machinery, and national defense weapons and equipment are usually made of steel, such as track shoes for tractors, tanks, and armored vehicles. These steel track shoes run on cement, asphalt and high-quality ground, causing serious damage to the ground. In order not to damage the ground, the relevant personnel are trying to use a material to wrap the outside of the steel track shoes, and can choose a material that can make them bond to each other, and use a processing method to fasten them together. These are all issues that relevant technical personnel need to solve. Contents of the invention [0003] In order to solve the problem of ground damage caused by...
