Problems solved by technology

The corrosion of the water-cooled tube wall of industrial boilers has always been an important economic and technical problem. During service, the tubes will fail prematurely due to corrosion and erosion, and the replacement of the tubes is very expensive; fluid machinery will always encounter fluid or fluid during work. Particle erosion causes damage to mechanical surfaces
The existing metal anti-corrosion technology generally adopts two methods: one is to use anti-corrosion materials such as stainless steel or glass fiber reinforced plastic, which has the advantage of long corrosion resistance life, but the price is too high, and contact corr...

Embodiment 1

[0020] Take by weighing thermoplastic polyamide resin 100g, carbon fiber 0.2g, molybdenum disulfide 1g, gamma-glycidyl ether propyl trimethoxysilane 0.05g, use the mixed solvent of 300ml acetone and dehydrated alcohol (volume ratio is: acetone: no Water ethanol = 1:1) to wet the mixture, heat and stir to volatilize the solvent, when the mixture becomes lumpy, move it into an oven, dry it at 80°C, and sieve the mixture to 80 mesh to form a powder coating.

[0021] Use CMD-PS type plastic powder spraying equipment to spray the treated mixture on the surface of metal parts. First, roughen and purify the surface of the metal parts, and then use the flame to preheat the metal parts to 80 ℃, adjust the spraying parameters: acetylene gas pressure 0.05 ~ 0.1MPa, compressed air pressure 0.4MPa, powder feeding gas pressure 0.4MPa, and then Spray and cool naturally to obtain a certain thickness of polymer composite coating. When spraying, the distance from the nozzle to the surface to b...

Embodiment 2

[0023] 100 g of polyamide resin, 0.6 g of carbon fiber, 1 g of molybdenum disulfide, γ-glycidyl ether propyl trimethoxysilane: 0.05 g. The preparation method is as in Example 1.

Embodiment 3

[0025] 100 g of polyamide resin, 1 g of carbon fiber, 1 g of molybdenum disulfide, γ-glycidyl ether propyl trimethoxysilane: 0.1 g. The preparation method is as in Example 1.

Abstract

A corrosion-resistant and anti-friction powder coating and its production are disclosed. The powder coating consists of base material, filler and coupler. Base material is chosen from thermoplastic polyamide resin, filler is carbon fibre and coupler is gamma-glycidol ether propyl-trimethylsilane for improving filler and base material compatibility. The process is carried out by spraying on metal part surface from flame spraying technology. It has no pores, excellent impact resistance, corrosion-resistant and anti-friction performances. It can be used for food machinery, papermaking machinery, propeller and petroleum and chemical containers.

Description

technical field [0001] The invention relates to a corrosion-resistant and wear-resistant powder coating and a preparation method thereof. Background technique [0002] Corrosion is the most important reason for the failure of many metal materials, equipment and containers, and the economic losses caused by it every year in the world are quite staggering. The corrosion of the water-cooled tube wall of industrial boilers has always been an important economic and technical problem. During service, the tubes will fail prematurely due to corrosion and erosion, and the replacement of the tubes is very expensive; fluid machinery will always encounter fluid or fluid during work. The erosion of particles causes damage to mechanical surfaces. The existing metal anti-corrosion technology generally adopts two methods: one is to use anti-corrosion materials such as stainless steel or glass fiber reinforced plastic, which has the advantage of long corrosion resistance life, but the price...
