Problems solved by technology

However, in more demanding application fields and further research, nylon is brittle at low temperature and dry state, which greatly limits its application.
For example, the traditional nylon 66, nylon 610 and nylon 612 have high crystallinity. Although they have strong mechanical strength, they have disadvantages such as poor toughness and poor wear resistance. They are difficult to withstand special environments and meet the requirements of high-speed transmission equipment.

Abstract

The invention relates to the field of engineering machinery, in particular to a nylon composite material for engineering machinery and a preparation method thereof. The nylon composite material for engineering machinery comprises the following raw materials in parts by weight: 100 parts of aminoundecanoic acid, 10-20 parts of adipic acid, 0.05 part of scandium chloride and 0.04-0.25 part of silicon nitride hybrid. The invention discloses a nylon composite material for engineering machinery. The nylon composite material specifically comprises the following raw materials in parts by weight: 100parts of aminoundecanoic acid, 15 parts of adipic acid, 0.05 part of scandium chloride and 0.1 part of silicon nitride hybrid. The nylon composite material of the invention solves the defects of poortoughness, poor wear resistance and the like of conventional nylon materials and overcomes the problem that conventional nylon materials are difficult to withstand special environments and adapt to the requirements of high-speed transmission instruments. By introducing a silicon nitride hybrid into the nylon material, the toughness of the nylon material in a low-temperature state is further enhanced; and in addition, the wear resistance of the nylon material is also enhanced by adding rare earth elements.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a nylon composite material for construction machinery and a preparation method thereof. Background technique [0002] With the high development of modern construction engineering and transportation, the application of vehicle handling and cranes is becoming more and more extensive. The requirements for cables that provide power are getting higher and higher. In recent years, welding technology has advanced by leaps and bounds, and construction machinery is also striving for stronger, more accurate, longer service life and lower operating costs for users. The main components of construction machinery are cables. The design of cables is the key to the overall performance and service life of the product. Therefore, a cable with long service life, excellent mechanical resistance and high cost performance is required. [0003] As the earliest developed variety of nylon engineeri...
