Abstract

The invention discloses a modified nylon 1012 powder coating and a preparation method thereof. The nylon powder coating is prepared by uniformly mixing decamethylene diamine, dodecanedioic acid and a modifying agent, carrying out polycondensation and carrying out extrusion modification-cryogenic grinding or solvent grinding, wherein the mass percents of the decamethylene diamine, the dodecanedioic acid and the modifying agent are respectively 25-40%, 35-54% and 6-40%. The modified nylon 1012 powder coating and the preparation method have the following beneficial effects that the modified nylon 1012 powder coating can overcome such defects of the ordinary nylon 1012 powder as high melting point, poor powder flowability and difficult construction and has the characteristics of good powder flowability and convenience in thermal spraying construction; the preparation method is simple and is easy to implement; the product yield is high; the grain size of the powder is easy to control; and the modified nylon 1012 powder coating can realize large scale production and is convenient to popularize and apply.

Description

technical field [0001] The invention relates to powder coatings in the field of polymer materials, in particular to modified nylon 1012 powder coatings and a preparation method thereof. Background technique [0002] Nylon 1012 is a kind of long carbon chain nylon. It has excellent toughness, low temperature resistance, wear resistance, low water absorption and good dimensional stability. It has been widely used in the manufacture of various pipeline materials. Introducing nylon 1012 in the form of powder coating to the surface of wires, cables, optical cables or metals for coating can effectively improve the mechanics, chemical resistance and friction resistance of the overall material on the basis of maintaining the original material properties. Therefore, the development and development of nylon 1012 powder coatings can improve the performance of materials, prolong the service life of materials, and produce good economic and social benefits. [0003] The method for prepar...
