Abstract

The invention discloses a treble block for hoisting machinery. The treble block comprises a metal axle, which is treated by coating. The coating comprises the steps of 1) adding 1-2 parts of N- phenyl- 2- naphthylamine (by weight), 2.2 parts of itaconic acid (by weight), 1.8 parts of hydroxypropyl cellulose (by weight), 0.7 parts of sodium alkylary sulfonate (by weight) in 45 parts of deionized water (by weight) in sequence and mixing even; 2) Adding 4.1 parts of methyl acrylate (by weight), 9.8 parts of coplymer terpolymer of acrylic resin and polyurethane (by weight), 1.3 parts of alkyl sodium sulfonate (by weight), 0.5 parts of sodium molybdate (by weight) and mixing even to obtain the coating solution; 3) Soaking the metal axle in the coating solution, getting out and letting it dry. The treble block for hoisting machinery has a coating on the surface, with good performance and surface smoothness.

Description

technical field [0001] The invention relates to a three-wheel tackle for hoisting machinery. Background technique [0002] Existing hoisting machinery uses three-wheel blocks, and the antirust, abrasion resistance, oxidation resistance, corrosion resistance, heat resistance, cold resistance, weather resistance performance of its metal axle needs to be improved, and the surface smoothness is also not ideal enough. Contents of the invention [0003] The purpose of the present invention is to provide a three-wheeled tackle for hoisting machinery, the metal axle of which is coated with a film, and the surface of the metal axle is covered with a protective film, which has excellent rust resistance, abrasion resistance, oxidation resistance, corrosion resistance, heat resistance, Cold resistance, weather resistance, and good surface finish. [0004] In order to achieve the above object, the technical solution of the present invention is to design a three-wheel tackle for hoisti...
