Description

Sound absorption damping coating containing piezoelectric ceramic fiber and preparation method thereof
Technical Field
The invention belongs to the technical field of chemical coating production, and particularly relates to a sound absorption damping coating containing piezoelectric ceramic fibers and a preparation method thereof.
Background
The sound absorption damping coating is a common chemical coating, the sound absorption and insulation principle lies in a damping loss factor, a damping constraint structure can be formed inside the coating, when the sound impact coating vibrates, a layer of damping protective layer can be formed inside the sound absorption damping coating, and the mechanical energy of sound waves can be effectively converted into heat energy to be dissipated, so that the sound insulation effect is improved. The sound absorption damping coating is widely applied to ventilation pipelines, water supply and sewerage pipelines, sound insulation room partition boards, vehicle side plates, bottom plates and the like, and plays a sound insulation role.
In the existing sound absorption damping paint, in order to improve the sound absorption effect, the glass transition temperature of matrix resin is generally designed, the sound insulation effect can be improved by reducing the glass transition temperature of the matrix resin, but the mechanical property of the coating is reduced by too low glass transition temperature, and a thicker coating needs to be coated, so the using amount of the paint is increased.
In the Chinese patent application CN103483957A (a sound absorption damping paint), aluminum fibers with the diameter of 20-500 μm and the length of 1-30mm are added into the paint, the aluminum fibers have good sound absorption effect on low-frequency noise, and the paint is suitable for indoor sound absorption walls made of metal materials and can weaken the vibration of metal plate walls. However, the coating contains silicone which has certain environmental pollution, strong corrosiveness and irritation to human skin, eyes and the like and is harmful to human health.
Therefore, a sound absorption damping coating is required to be developed, which has good environmental friendliness and high sound absorption damping strength, and meets the requirements of practical application.
Disclosure of Invention
The invention provides a sound absorption damping coating containing piezoelectric ceramic fibers and a preparation method thereof, which aim to solve the technical problems mentioned in the background technology.
In order to solve the technical problem, the invention discloses a sound absorption damping coating containing piezoelectric ceramic fibers, which comprises the following components in parts by weight:
Figure BDA0002992150870000011
Figure BDA0002992150870000021
further, the acrylic emulsion comprises a first acrylic emulsion and a second acrylic emulsion, wherein the Tg of the first acrylic emulsion is 21-24 ℃, and is preferably 22 ℃; the Tg of the second acrylic emulsion is between-17 ℃ and-14 ℃, preferably-15 ℃.
Further, the mass portion of the first acrylic emulsion is 11-16; the second acrylic emulsion is 9-12 parts by weight.
The first acrylic emulsion is matrix resin with high glass transition temperature, the second acrylic emulsion is matrix resin with low glass transition temperature, and the two matrix resins are matched for use, so that the use temperature range of the coating can be enlarged, and the coating has better sound absorption and damping performance in a wider temperature range.
Further, the mica powder comprises a first mica powder and a second mica powder, wherein the particle size of the first mica powder is 400 meshes, and the particle size of the second mica powder is 120 meshes.
Further, the first mica powder and the second mica powder are used in the same amount, and the mass portions of the first mica powder and the second mica powder are respectively 18-21.
The particle size of the first mica powder is smaller than that of the second mica powder, the corrosion resistance, the mechanical strength and the flame retardant property of the coating can be improved by adding the mica powder into the coating, and the performance of the mica powder can be better exerted and the comprehensive performance of the coating can be improved by matching the two mica powders with different particle sizes.
Further, the coating also comprises deionized water. In order to ensure the storage and production performance of the coating, deionized water can be added to adjust the viscosity of the coating; meanwhile, in the using process of the coating, the viscosity of the coating can be adjusted by adding a proper amount of deionized water according to the construction condition.
In the above-mentioned coating material, the aqueous dispersant may be one or more of all commercially available aqueous dispersants, for example, acrylate polymers and sodium acrylate polymers, and sodium hexametaphosphate is preferred in the present invention. The flame retardant may be selected from one or more of all commercially available flame retardant fillers, for example, bromine-based, nitrogen-phosphorus-based, nitrogen-based, red phosphorus-based, silicon-based, antimony trioxide, magnesium hydroxide, aluminum hydroxide and the like, and TPP powder is preferred in the present invention.
Further, the length of the piezoelectric ceramic fiber is 2-4 mm.
Further, the length of the carbon fiber is 1-3 mm.
Piezoelectric ceramic fiber and carbon fiber can overlap joint each other and form network crosslinked structure for in the coating, the length of piezoelectric ceramic fiber and carbon fiber can not the overlength, in the overlength, can influence the spraying of coating, because coating need pack into the spray gun and spout, the fibre is too long, and coating can block up the rifle head, leads to the unable normal spraying of coating to it is inhomogeneous to cause spun coating, and then influences the performance of coating. However, the lengths of the piezoelectric ceramic fibers and the carbon fibers cannot be too short, and because the too short lengths cannot form effective network cross-linked structure lap joints between the fibers, a passage cannot be formed, and heat in the coating cannot be dissipated.
According to the invention, the carbon fiber with the conductive property is added into the coating, after the piezoelectric ceramic fiber in the coating absorbs the sound energy capable of generating vibration, the vibration generates pressure to enable the piezoelectric ceramic fiber to convert the sound energy into electric energy, then the electric energy is converted into heat energy through the carbon fiber with the conductive property, and finally the heat energy is dissipated out in a form of heat energy, so that the sound absorption property of the coating can be greatly improved.
Further, the preparation method of the piezoelectric ceramic fiber comprises the following steps:
(1) adding piezoelectric ceramic raw material powder into a ball mill, grinding and then pre-burning, adding the pre-burned piezoelectric ceramic raw material powder into the ball mill, dropwise adding oleic acid, and drying for later use after ball milling;
