Embodiment 1

[0021] 1) Heating: Weigh 10 kg of caprolactam and place it in a stainless steel container, heat it with a resistance wire furnace at 150°C until the caprolactam melts into a molten state;

[0022] 2) Dehydration: Add 10 kg of molten caprolactam obtained in step 1) into a vacuum dehydration device (can be a vacuum dehydration pot) for secondary heating, and at the same time connect it to the dehydration system of the vacuum dehydration device for dehydration treatment. The purpose is to remove all the water in caprolactam under high temperature and negative pressure environment. The specific operation steps are: after feeding caprolactam, add 12 grams of sodium hydroxide and 2 grams of Gomet Touhuang, mix well, start the electric furnace and heat to 150 °C , and then start the vacuum pump to stabilize the pressure at -0.10MPa, and perform dehydration treatment for 8 minutes;

[0023] 3) Pouring: Open the mold oven, preheat the mold, the preheating temperature of the upper mold ...

Embodiment 2

[0027] 1) Heating: Weigh 10 kg of caprolactam and place it in a stainless steel container, heat it with a resistance wire furnace at 170°C until the caprolactam melts into a molten state;

[0028] 2) Dehydration: Add 10 kg of molten caprolactam obtained in step 1) into a vacuum dehydration device (can be a vacuum dehydration pot) for secondary heating, and at the same time connect it to the dehydration system of the vacuum dehydration device for dehydration treatment. The purpose is to remove all the water in caprolactam under high temperature and negative pressure environment. The specific operation steps are: after feeding caprolactam, add 14 grams of potassium hydroxide and 4 grams of permanent yellow, mix well, start the electric furnace and heat to 165 ° C, Start the vacuum pump again to stabilize the pressure at -0.08MPa, and perform dehydration treatment for 5 minutes;

[0029] 3) Pouring: Open the mold oven, preheat the mold, the preheating temperature of the upper mol...

Embodiment 3

[0033] 1) Heating: Weigh 10 kg of caprolactam and put it in a stainless steel container, heat it with a resistance wire furnace at 160°C until the caprolactam melts into a molten state;

[0034] 2) Dehydration: Add 10 kg of molten caprolactam obtained in step 1) into a vacuum dehydration device (can be a vacuum dehydration pot) for secondary heating, and at the same time connect it to the dehydration system of the vacuum dehydration device for dehydration treatment. The purpose is to remove all the water in caprolactam under high temperature and negative pressure environment. The specific operation steps are: after feeding caprolactam, add 13 grams of sodium hydroxide and 3 grams of Gomet Touhuang, mix well, start the electric furnace and heat to 160°C , and then start the vacuum pump to stabilize the pressure at -0.09MPa, and perform dehydration treatment for 6 minutes;

[0035] 3) Pouring: Open the mold oven and preheat the mold. The preheating temperature of the upper mold ...

Abstract

The invention relates to the field of engineering plastic, in particular to a preparation method for a high-strength MC (monomer casting) nylon wheel for elevator transmission. The preparation method comprises the steps as follows: heating, dehydrating, pouring, forming and processing in sequence to prepare the high-strength MC nylon wheel which overcomes the shortage of nylon wheels prepared by the existing preparation method, is better in flexibility and wear resistance, lighter in self weight and easy to mount, is prolonged in service life and is provided with a wheel groove for protecting a steel wire rope.

Description

technical field [0001] The invention relates to the field of engineering plastics, in particular to a preparation method of a high-strength MC nylon wheel used for elevator transmission. Background technique [0002] Due to its non-toxic, light weight, wear-resistant and other excellent properties, nylon is widely used instead of copper and other metals in machinery, chemical industry, instrumentation, automobile and other industrial fields. MC nylon with more outstanding performance can even directly replace metal products such as copper, stainless steel, and aluminum alloy. Reduce user costs and prolong service life. [0003] In the prior art, traditional methods are mostly used for the preparation of MC nylon wheels, but the MC nylon wheels prepared by traditional methods have been unable to adapt to the rapid development of the modern elevator industry, and cannot meet the higher requirements of the modern elevator industry for its performance.
