Description

Technical Field

[0001] This utility model relates to the field of coatings, and in particular to a heat-resistant, high-strength alkyd insulating varnish coating. Background Technology

[0002] With the rapid development of industrial equipment, power facilities, and high-end equipment, higher requirements are placed on the comprehensive performance of material surface coatings, especially under harsh working conditions such as high temperature, strong corrosion, mechanical impact, and complex electrochemical environments. Traditional single-function coatings often struggle to achieve a synergistic improvement in heat resistance, insulation strength, mechanical toughness, and long-term corrosion resistance. Conventional alkyd resin coatings are prone to increased brittleness due to improper oil control, making them susceptible to cracking under thermal stress. While single epoxy coatings possess good adhesion, their weather resistance and UV resistance are insufficient, making them unsuitable for long-term outdoor exposure. Furthermore, the coupled effects of multiple factors such as electrochemical corrosion, media penetration, and high-temperature oxidation in industrial equipment often lead to coating system failure, causing safety hazards. Therefore, there is an urgent need to develop an alkyd insulating varnish coating that integrates rust prevention, insulation, heat resistance, impact resistance, and ultra-weather resistance to meet the requirements for long-term protection and functional stability of coatings under complex working conditions. Utility Model Content

[0003] To overcome the shortcomings of conventional alkyd resin coatings, which are prone to increased brittleness and cracking under thermal stress due to improper oil control, and single epoxy coatings, which, although possessing good adhesion, lack sufficient weather resistance and UV resistance and cannot adapt to long-term outdoor exposure environments, this invention aims to provide an alkyd insulating varnish coating that integrates rust prevention, insulation, heat resistance, impact resistance, and ultra-weather resistance, meeting the requirements for long-term protection and functional stability of the coating under complex working conditions.

[0004] This utility model is achieved by the following specific technical means:

[0005] A heat-resistant, high-strength alkyd insulating varnish coating includes a primer layer, an insulating layer, a heat-resistant layer, a high-strength layer, and a protective outer layer; the primer layer is uniformly coated on the surface of a substrate; the insulating layer is uniformly coated on the outer side of the primer layer; the heat-resistant layer is uniformly coated on the outer side of the insulating layer; the high-strength layer is uniformly coated on the outer side of the heat-resistant layer; the protective outer layer is uniformly coated on the outer side of the high-strength layer; the coating consists of, from the inside out, the primer layer, the insulating layer, the heat-resistant layer, the high-strength layer, and the protective outer layer.

[0006] Furthermore, the primer layer is an epoxy iron oxide red primer layer; the epoxy iron oxide red primer has excellent anti-rust properties, and the paint film has high hardness, high temperature resistance, strong adhesion, and good mechanical properties.

[0007] Furthermore, the insulating layer is an epoxy micaceous iron oxide intermediate paint layer; the two-component epoxy anti-rust paint, composed of epoxy resin, flake mica iron oxide, anti-rust pigment, polyamide resin curing agent, additives, and solvent, has high sealing and impermeability, heat resistance, and resistance to media corrosion, as well as good mechanical properties, and the paint film is tough and impact resistant.

[0008] Furthermore, the heat-resistant layer is a high-chlorinated polyethylene anti-corrosion paint layer; the high-chlorinated polyethylene anti-corrosion paint has excellent weather resistance, corrosion resistance and flame retardancy, and has excellent anti-corrosion performance against industrial atmosphere, "three wastes" polluting media and different concentrations of acids, alkalis, salts, mineral oils and other corrosive media.

[0009] Furthermore, the high-strength layer is a short-oil alkyd resin layer; the short-oil alkyd resin has high toughness and impact resistance, increasing the overall toughness of the coating and playing a role in preventing cracking and impact.

[0010] Furthermore, the protective outer layer is a fluorocarbon anti-corrosion paint layer; the fluorocarbon anti-corrosion paint has excellent adhesion, hardness and super weather resistance, strong UV resistance, and excellent resistance to acids, alkalis, salt spray and various chemicals.

[0016] The present invention will be further described below with reference to the accompanying drawings: Example

[0017] A heat-resistant, high-strength alkyd insulating varnish coating, such as Figure 1As shown, the coating includes a primer layer 1, an insulating layer 2, a heat-resistant layer 3, a high-strength layer 4, and a protective outer layer 5. The primer layer 1 is uniformly coated on the surface of the substrate. The insulating layer 2 is uniformly coated on the outside of the primer layer 1. The heat-resistant layer 3 is uniformly coated on the outside of the insulating layer 2. The high-strength layer 4 is uniformly coated on the outside of the heat-resistant layer 3. The protective outer layer 5 is uniformly coated on the outside of the high-strength layer 4. The coating consists of, from the inside out, the primer layer 1, the insulating layer 2, the heat-resistant layer 3, the high-strength layer 4, and the protective outer layer 5.

[0018] Working principle:

[0019] This utility model's insulating varnish coating achieves multiple protective effects through the gradient superposition of multiple functional materials. The primer layer 1, located on the innermost side, is uniformly coated on the substrate surface. The primer layer 1 uses epoxy iron oxide red primer as the base interface, forming a chemical bond with the substrate through high adhesion, constructing a rust-proof base and enhancing the bonding strength of subsequent coatings. An insulating layer 2 is uniformly coated on the outer surface of the primer layer 1. The insulating layer 2 is an epoxy micaceous iron oxide intermediate varnish, a two-component epoxy rust-proof varnish composed of epoxy resin, flake-like mica iron oxide, rust-proof pigments, polyamide resin curing agent, additives, and solvents. The insulating layer 2 forms a physical barrier layer through the directional arrangement of the flake-like mica iron oxide in the epoxy micaceous iron oxide intermediate varnish, blocking electrochemical corrosion channels. Its dense structure effectively isolates medium penetration. A heat-resistant layer 3 is uniformly coated on the outer surface of the insulating layer 2. The heat-resistant layer 3 is a high-chlorinated polyethylene anti-corrosion paint layer. Relying on the molecular cross-linking network of high-chlorinated polyethylene, it maintains structural stability at high temperatures and resists thermal degradation and chemical corrosion through the high bond energy characteristics of chlorine. The outer surface of the heat-resistant layer 3 is uniformly coated with a high-strength layer 4, which is a short-oil alkyd resin layer. The flexible segments and rigid groups of the short-oil alkyd resin work together to absorb impact energy through the elastic deformation of the molecular chains under mechanical stress. The outer surface of the high-strength layer 4 is uniformly coated with a protective outer layer 5, which is a fluorocarbon anti-corrosion paint layer. The fluorocarbon anti-corrosion paint has excellent adhesion, hardness, and super weather resistance. It has strong UV resistance and excellent resistance to acids, alkalis, salt spray, and various chemicals. By constructing an inert surface with fluorocarbon resin, it achieves self-cleaning of pollutants through its low surface energy characteristics.
