Abstract
The invention proposes a kind of acrylic emulsions of damping paint, according to the number of parts by weight, including following raw material: 150~170 parts of butyl acrylate, 90~110 parts of styrene, 35~45 parts of methyl methacrylate, acrylic acid α -112~122 parts of ethylhexyl, 10~14 parts of methacrylic acid, 8~11 parts of ammonium acrylate, 13~17 parts of acrylonitrile, 390~450 parts of water, 1.2~2.2 parts of thermal decomposition initiating, 1.4~2.2 parts of oxidation-reduction initiator system, 3~4 parts and 0.5~1 part of emulsifier of pH adjusting agent, wherein, the oxidation-reduction initiator system is made of 0.6~1 part and 0.8~1.2 part oxidant of inorganic reducing agent.The acrylic emulsion auxiliary agent can substitute plasticizer with lesser partial size and higher solid content, can be improved the stability of product applied to substitution plasticizer in terms of damping paint, enhance salt spray resistance and corrosion resistance.
Description
Technical field
The invention belongs to acrylic emulsion technical fields, and in particular to a kind of acrylic emulsion of damping paint.
Background technique
One layer of damping paint, such as pipeline, device housings, metallic sound barrier surface are coated in metal structure, are to inhibit
Structural vibration, a kind of common effective measures for reducing noise.But common damping paint thermal conductivity is poor, limits it and is becoming
The application that depressor, reactor etc. have higher requirements in equipment to heat dissipation.
Damping paint is to be converted to the mechanical vibrational energy of sound wave using viscoelastic property possessed by high-molecular organic material
Thermal energy releases (i.e. mechanical loss), reduces amplitude to reach, reduces vibration, inhibiting the purpose of noise.However tradition resistance
No matter damping paint has a large amount of poisonous and harmful using organic solvent as decentralized medium during production process and construction application
The discharge of gas, waste water pollutes environment, atmosphere and water resource, and the seriously body of damage production and construction personnel
Body health.And aqueous damping coating is one kind using water as main dispersing medium, using inorganic matter and organic matter as filler, without any
The green environmental friendly coatings of toxic organic solvents.Simultaneously because aqueous damping coating has good anti-flammability, high adhesion force, corrosion resistant
Corrosion, ageing resistance, high damping properties and it is easy for construction the advantages that, be just widely used at present automobile, train, steamer, fly
Machine, engineering machinery and other household appliance technical fields, play sound insulation, sound absorption, vibration damping and insulation effect.
However, conventional damper coating and aqueous damping coating are required to addition plasticizer as auxiliary agent, a large amount of plasticizer
The phenomenon that addition can bring the coating later period to thicken, causes coating products performance unstable, and salt spray resistance and corrosion resistance
It is affected significantly.
Summary of the invention
The present invention proposes a kind of acrylic emulsion of damping paint, the acrylic emulsion can substitute plasticizer have compared with
Small partial size and higher solid content can be improved the stability of product applied to substitution plasticizer in terms of damping paint, increase
Strong salt spray resistance and corrosion resistance.
The technical scheme of the present invention is realized as follows:
A kind of acrylic emulsion of damping paint, according to the number of parts by weight, including following raw material:
150~170 parts of butyl acrylate, 90~110 parts of styrene, 35~45 parts of methyl methacrylate, acrylic acid α-
112~122 parts of ethylhexyl, 10~14 parts of methacrylic acid, 8~11 parts of ammonium acrylate, 13~17 parts of acrylonitrile, water 390~
450 parts, 1.2~2.2 parts of thermal decomposition initiating, 1.4~2.2 parts of oxidation-reduction initiator system, 3~4 parts of pH adjusting agent and cream
0.5~1 part of agent, wherein the oxidation-reduction initiator system is aoxidized by 0.6~1 part and 0.8~1.2 part of inorganic reducing agent
Agent composition.
It further, further include 1~2 part of fungicide.
Further, the fungicide is chlormethylisothiazo,ine ketone.
Further, 160 parts of butyl acrylate, 100 parts of styrene, 40 parts of methyl methacrylate, acrylic acid α-ethyl hexyl
117 parts of ester, 12 parts of methacrylic acid, 9 parts of ammonium acrylate, 15 parts of acrylonitrile, 1.7 parts of thermal decomposition initiating, redox initiator
1.8 parts of agent system, 2.5 parts and 0.7 part of emulsifier of pH adjusting agent.
Further, the thermal decomposition initiating is ammonium persulfate, potassium peroxydisulfate, sodium peroxydisulfate or hydrogen peroxide.
