Waterproof antiseptic wearproof nano paint, preparation method, use method and application thereof

Abstract

The invention discloses a waterproof antiseptic wearproof nano paint, a preparation method, a use method and application thereof. The paint has a middle layer, a surface layer or a bottom layer, a middle layer and a surface layer outwards orderly from the contact surface of a metal substrate surface; each layer comprises components by weight percent: the bottom layer comprises 10% to 25% of epoxysolution, 10% to 25% of polyamide solution, 50% to 78% of zinc powder and 2% to 10% of ferrous phosphorus powder; the middle layer comprises 15% to 30% of epoxy solution, 10% to 28% of polyamide solution, 42% to 70% of micaceous iron oxide, 2% to 10% of ferrous phosphorus powder and 2% to 8% of talcum powder; the surface layer comprises 25% to 50% of modified epoxy resin solution, 20% to 44% of polyamide solution, 5% to 20% of carborundum, 0.5% to 3% of nano carborundum and 10% to 25% of alumina and proper defoaming agents are added respectively to each layer of paint. The paint largely enhances the waterproof, antiseptic and wearproof performance of substrate, largely prolongs the service life and has good market prospect and practical popularization value.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a waterproof, anti-corrosion and wear-resistant nano-coating coated on the surface of metal materials, its preparation and use methods and applications. Background technique [0002] Metal materials will be affected by natural environments such as air, water erosion, acid and alkali during use. With the extension of the action time, the performance of the material itself will gradually decrease or even be damaged. The annual loss due to metal aging is huge all over the world. According to statistics, more than 90% of the use of metal materials is steel. The annual corrosion rate of existing steel and metal equipment in the world is about 10%, and the annual loss due to corrosion in the world is about 700 billion US dollars. The resulting economic loss accounts for about 2% to 4% of the gross output value of the national economy. [0003] Applying suitable coatings ...

Problems solved by technology

Inorganic anti-corrosion and wear-resistant coatings are generally water-soluble coatings based on inorganic binders, which have poor water resistance and erosion resistance and are not suitable for working conditions in humid environments; general organic anti-corrosion and wear-resistant coatings It is prepared by using epoxy resin as a binder and adding a certain amount of large particle ceramic aggregate and curing agent.

Although epoxy resin has excellent bonding force and mechanical strength, it lacks toughness and is brittle

Especially for workpieces under slurry erosion and wear conditions and hydraulic machinery components that are often eroded by quicksand, the working environment is very harsh, and the requirements for anti-corrosion, anti-corrosion, and wear-resistant coatings on the surface of workpieces are very high. Existing coatings are basically Can't meet demand
