Problems solved by technology

When the traditional modification method increases the impact toughness of the material, its tensile strength, stiffness and other related properties decrease, and when the tensile strength and stiffness of the material are increased, its toughness becomes worse, so it is always at the expense of a certain material. Aspect performance at the expense of trade-offs

Embodiment Construction

[0013] A kind of production technology of nanometer samarium oxide modified MC nylon slider, comprising 15.5 kilograms of masterbatch caprolactam, 80 grams of nanometer samarium oxide, 19 grams of accelerator sodium hydroxide, 52 milliliters of curing agent TDI, 320 grams of solid lubricant molybdenum disulfide, 80 grams of graphite, 55 grams of boron nitride.

[0014] The specific production process is as follows:

[0015] 1) Heating the mould: evenly coat the bottom mold of this specification with the mold release liquid, fix it on the flower plate in the heating box, start heating and measure the temperature; evenly brush the mold release liquid on the upper mold, Put it in another heating box to heat and measure the temperature. When the temperature of the bottom mold is 170°C and the temperature of the upper mold is 200°C, install the upper mold of the mold on the bottom mold and start pouring;

[0016] 2) Feeding: Put 15.5 kg of monomeric caprolactam masterbatch into th...

Abstract

The invention relates to MC nylon engineering plastics and production process thereof. The MC nylon engineering plastics include 100 parts of masterbatch caprolactam, 1-2 parts of nanometer samarium oxide, 0.15-0.25 part of an accelerant sodium hydroxide, 0.5-1 liter of a curing agent TDI, 3-4 parts of a solid lubricant MoS2, 0.8-1.5 parts of graphite and 0.5-0.8 part of boron nitride. The production process comprises the specific steps of mould heating, feeding, curing molding, stress treatment and machining. The product of the invention can effectively transfer the external stress, and can lead to matrix yielding and consume a large amount of impact energy, so as to enhance the toughness and strength of the product. The production process of the invention employs a centrifugal casting technology, eliminates the inner pores of the product, overcomes the product quality problems of steel slider caused by internal pores and inclusion.

Description

technical field [0001] The invention relates to an MC nylon engineering plastic and a production process, in particular to a nano samarium oxide modified MC nylon engineering plastic and a production process. Background technique [0002] MC nylon is a new type of engineering plastic made of caprolactam as the main raw material through anionic polymerization under normal pressure. MC nylon is gradually replacing copper, aluminum, steel and other metal materials and is widely used in textile, rubber, petrochemical, steel rolling, mining machinery, automobile, elevator, crane and other industries. However, compared with metals, MC nylon also has disadvantages such as lower strength, modulus and heat distortion temperature, higher water absorption, and poorer dimensional stability. In recent years, research on modified MC nylon has been active at home and abroad. Common modification methods are mainly carbon fiber or glass fiber reinforcement, inorganic particle filling, copo...
