Embodiment Construction

[0027] Take 80~160g of copper powder, 20~40g of iron powder, 4~8g of chromium powder, 5~10g of ferrochrome powder, 2~4g of silicon dioxide and 20~40g of engine oil and fully mix them in the mixing equipment to obtain the mixture. The mixture is cold-pressed to obtain the lock cylinder matrix; take 10-20g of zinc phosphate and place it in 150-300g of 13mol / L ammonia solution, stir until dissolved, and obtain the modified solution; put the lock cylinder matrix into the modified solution , take it out after 1h, and dry to obtain the modified lock core matrix; take 2~4g of graphite and 1~2g of anhydrous sodium nitrate and pour it into 35~70g18mol / L sulfuric acid solution under ice-water bath conditions, add 8~ 16g of potassium permanganate, stirred at 30°C for 1 hour to obtain mixed solution A; add 50~100g of deionized water to the mixed solution and continue to stir for 30min, control the temperature at 90°C, add 20~40g of 10mol / L hydrogen peroxide solution, Obtain the mixed solu...

Abstract

The invention relates to a preparation method of a self-lubricating novel material for a lock cylinder, and belongs to the technical field of new materials. A high-hardness and corrosion-resistant lock cylinder base body is formed by cold pressing of copper powder, iron powder, chromium powder and the like, when the lock cylinder base body enters a modification liquid for modification, copper on asurface of the lock cylinder base body reacts with ammonium hydroxide, a multi-particle shaped complex is formed at a surface layer of the lock cylinder base body, phosphate ions in the modificationliquid slowly react with zinc ions and the lock cylinder base body to generate a phosphating film with complicated constituents, compactness and firm adhesion, the phosphating film is pasted onto a surface of the lock cylinder base body, so that the lock cylinder base body is passivated, and an effect of rust prevention can be achieved; nanometer tungsten carbide particles are grown on a surface of graphene oxide in an in-situ way and are then sprayed onto an outer surface of the lock cylinder to form a high-hardness protection film, relatively high hardness can be maintained as well as the self-lubricating capability is improved, the scrape to the lock cylinder due to increase of application is reduced, and the service lifetime of the lock cylinder is prolonged.

Description

technical field [0001] The invention relates to a preparation method of a new self-lubricating material for a lock cylinder, belonging to the technical field of new materials. Background technique [0002] Locks are one of the daily necessities that can be seen everywhere in our daily life. There are many types of locks, such as padlocks, drawer locks, mortise locks, and ball locks. A lockset refers to a device that acts as a seal, including locks, keys and accessories. It is generally interpreted as "a seal that must be opened with a key." Now, in addition to being opened with a key, the lock can also be opened with light, electricity, Instructions such as magnetic, acoustic and fingerprint can be activated. The most widely used lockset is still based on key opening and closing. [0003] A typical lockset includes a lock case and a lock cylinder installed in the lock case. A deadbolt is installed on the lock cylinder, and a lock hole is arranged on the lock case. The lock...
