Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a dry high cold-resistant nylon material and a preparation method thereof. Background technique [0002] Due to its high mechanical strength, good wear resistance, stable chemical properties, and superior self-lubricating properties, nylon is widely used in industries such as auto parts, electronic appliances, and petrochemicals. However, nylon materials generally have poor heat resistance and acid resistance, low impact strength and poor solubility in dry and low temperature conditions, which affect the dimensional stability and electrical properties of the product, which greatly limits its application range. . Contents of the invention [0003] In view of this, the present invention provides a dry high cold-resistant nylon material and a preparation method thereof to improve the problems of poor heat resistance and acid resistance, low impact strength and poor solubility of ...
