Embodiment Construction

[0024] The present invention will be described in further detail below through specific examples. The following examples are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0025] A high-conductivity heavy-duty anti-corrosion wave-absorbing powder coating, the raw material constituents and their weight parts are:

[0026]

[0027] The preparation method is:

[0028] The above-mentioned materials are added to the high-speed mixer in parts by weight, and then added to the extruder after dry mixing. The extrusion temperature is 80-90℃ for conventional melting, mixing, cooling, and tableting, and then the pulverizer Crushing, grading, sieving, and packaging will become powder coating products.

[0029] The composition and function of each raw material are described below:

[0030] 1. Epoxy resin is a mixture of three types of epoxy resins. The composition of each component and the optimal weight parts are:

Abstract

The invention relates to a high-electric-conductivity heavy-anticorrosion wave-absorbing powder paint which is prepared from the following raw materials in parts by weight: 450-500 parts of epoxy resin, 50-100 parts of curing agent, 50-100 parts of conductive pigment, 200-250 parts of conductive filler and 30-50 parts of assistant. The preparation method of the high-electric-conductivity heavy-anticorrosion wave-absorbing powder paint comprises the following steps: adding the materials into a high-speed mixer; after carrying out dry mixing, adding the mixture into an extruder, and melting, mixing, cooling and pelleting at the extrusion temperature of 80-90 DEG C; and pulverizing with a pulverizer, grading, screening and packaging to obtain the finished powder paint product. The invention has the characteristic of high electric conductivity, has an absorption action on certain electromagnetic waves, can be used as a preferred coating for electromagnetic shielding, and is applied to thefields of frequency converter shells, micro-current and light-current component shells and the like. In addition, the invention has excellent anticorrosion property and favorable electric conductivity (105 ohm), and the conducting power is almost approximate to that of a metallic conductor; and thus, the high-electric-conductivity heavy-anticorrosion wave-absorbing powder paint is an ideal antistatic coating, and can ensure safety in the aspects of fire resistance and explosion resistance.

Description

Technical field [0001] The invention belongs to the field of coatings, and particularly relates to a highly conductive, heavy-duty anti-corrosion and wave-absorbing powder coating. Background technique [0002] Anti-corrosion and anti-static is a very important link in the manufacturing of equipment for mining, petroleum exploration and smelting, storage and transportation of flammable and explosive oil and gas, and an important guarantee for safety. The accumulation of static electricity is prone to instantaneous discharge. If there is combustible gas (or combustible liquid volatile matter) in the environment, an explosion may occur, causing serious casualties and property losses. When designing such equipment manufacturers, most of them fully consider this problem, requiring equipment coatings not only to have excellent anti-corrosion performance, but also to have good electrical conductivity, easy coating, electrical durability, low cost and other factors.
