Problems solved by technology

At present, nickel-based water-based coatings have good electromagnetic shielding performance and anti-oxidation performance, and are the mainstream of current water-based electromagnetic shielding coatings; copper-based water-based coatings have good electrical conductivity, but poor oxidation resistance. How to prevent copper oxidation in water is the current preparation of copper-based water-based coatings. Key technical issues; carbon-based water-based coatings have good corrosion resistance, low density, and low price, but relatively poor conductivity and insignificant electromagnetic shielding performance

Abstract

The invention discloses a composite polymer coating for buildings. The composite polymer coating is characterized by being prepared from the following raw materials in parts by weight: 65 parts of styrene-acrylic emulsions, 9 parts of serpentine powder with grain diameter of 2-5 microns, 7 parts of phosphogypsum powder with grain diameter of 5-10 microns, 1.2 parts of triethanolamine, 2.5 parts of benzene sulfinic acid sodium, 5 parts of zinc stearate, 2 parts of sodium dodecyl benzene sulfonate, 4 parts of praseodymium-neodymium alloy powder with grain diameter of 1-2 microns, 7.5 parts of nanometer ferrous powder with grain diameter of 20-30 microns, and 2 parts of tellurium powder with grain diameter of 2-3 microns. According to the composite polymer coating for buildings, composite functional powder which is prepared from nanometer ferric powder, praseodymium-neodymium alloy powder and tellurium powder are added; therefore, the composite polymer coating has a good electromagnetic shielding effect. The coating is in the frequency range of 100 kHz-1.5GHz, and the shielding efficiency can reach 62-78dB; meanwhile, the composite polymer coating is relatively high in physical performance and heatproof performance, and has a good waterproof effect.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a building coating, in particular to a polymer composite coating for building and a preparation method thereof. Background technique [0002] Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. It mainly includes the conceptual design of flat color, pattern and gloss and the conceptual design of three-dimensional pattern. However, it must be matched with the shape of the building itself and the size and shape of the base material itself, so that it can be fully utilized. The protection function refers to the function of protecting the building from the influence and damage of the environment. Different types of protected objects have different requirements for protect...
