Abstract
This invention discloses a method for manufacturing a polymer emulsion coating that can absorb electromagnetic waves, which adopts polymer emulsion as the coating material, and powders that can absorb electromagnetic waves and fibrous material as the fillers. Besides, film-forming assistant and surfactant are added to manufacture water polymer coating. After brushed or sprayed on the surface of architectures, the coating can form a coating layer. After vaporization of water in the coating layer, polymer particles interconnect with each other, and adheres the powders and the fibrous material to form a wave-absorption layer. The polymer emulsion coating in this invention has good electromagnetic wave-absorption property. The method has such advantages as simple process, easy operation and wide applications.
Description
Technical field
The present invention relates to a kind of polymer emulsion and prepare electromagnetic wave absorption coating and preparation method thereof as film forming matter.
Background technology
Environment electromagnetics pollution effect HUMAN HEALTH by electromagnetic radiation produces causes the attention of various countries day by day.Along with the enhancing of public's environmental consciousness, the improvement that hertzian wave is polluted will become one of important content of environmental protection.In the scope that electromagnetic radiation covered (public building, public place, resident living residential district etc.), adopt the novel environment friendly absorbing material, make buildings itself have certain absorption of electromagnetic wave ability, the environment electromagnetics intensity of wave can decay, effectively reduce electromagnetic environment and pollute, reduce the harm of electromagenetic wave radiation the resident.
Absorbing material can be divided into structure-type and coating type by moulding technology and supporting capacity.The structure-type wave-absorption material has carrying and reduces the reflection of electromagnetic wave dual-use function, normally wave absorbing agent is dispersed in the structured material, or good with wave, and the high polymer composite material that intensity is high is made panel, adopts that sandwich is cellular, corrugated or pyramid structure.The coating type absorbing material adopts powder, fiber absorbing materials such as the bonding metal of binding agent base, powdered alloy, ferrite, electro-conductive fiber to make microwave absorbing coating.Coating type absorbing material technology is simple, and is easy to use, regulates easily and come into one's own.
Absorbing material mainly contains electrical loss type and magnetic loss type.Electrical loss section bar material such as graphite, silicon carbide etc. have higher electrical loss tangent, rely on the electronic polarization of medium or interfacial polarization decay to absorb hertzian wave; Magnetic loss section bar material such as ferrite etc. have higher magnetic loss tangent angle, rely on magnetic polarization mechanism decay such as magnetic hysteresis loss, domain wall resonance and aftereffect loss, absorb hertzian wave.Ferrite is the absorbing material of comparative maturity, and absorbing property is good, and is cheap, is one of main component of absorbing material.
Usually the binding agent base phase material of the antiradar coatings that adopts has: Resins, epoxy; Urethane; Rubber.These materials need to adopt solvent or solidifying agent more in film process, environment is had certain pollution.
Summary of the invention
The object of the present invention is to provide a kind of have electromagnetic wave absorption ability, easy-to-use electromagnetic wave absorption coating that has more the environmental protection characteristics and preparation method thereof.The polymer emulsion Electromagnetic Absorber Coatings has absorbing property, and the employing polymer emulsion is a water-based material, as coating film forming material, environmentally safe.
The present invention is achieved through the following technical solutions:
Electromagnetic wave absorption coating of the present invention adopts polymer emulsion as the coating film forming material, is prepared into waterborne polymeric coating with powder, the fibrous material with electromagnetic wave absorption performance as filler, adding film coalescence aid and tensio-active agent.Form coating through brushing or spraying coating process at building surface.With the volatilization of moisture in the coating, polymer particles connects polymerization and the powder that bonds mutually, fibrous absorbing material forms and inhales the ripple layer.It is ornamental in microwave absorbing coating external coating one common building coating microwave absorbing coating to be had.Polymer emulsion is a water-based material, as the coating film forming material, and environmentally safe, the feature of environmental protection is good; Steam in the buildings can be overflowed by coating, compares with solvent based coating, and the coating weather resistance is better.
Polymer emulsion among the present invention is meant: any in polyacrylic acid emulsion, vinylbenzene-ACRYLIC EMULSION, polyvinyl acetate emulsion, vinyl acetate between to for plastic-ACRYLIC EMULSION, ethene-acetate emulsion, the neoprene emulsion.
Powder among the present invention, fibrous absorbing material are meant: the fiber of any one or more materials in metal, silicon carbide, graphite, barium titanate, carboxyl iron, ferrite, the mica powder.
Effect of the present invention: the microwave reflection loss (absorbing property) of having surveyed embodiment 2 polymer emulsion electromagnetic wave absorption coatings (2mm is thick) is shown in Fig. 1.In the frequency range of being tested, coating has good wave-absorbing effect.
