Description
Technical field
The invention belongs to damping paint technical fields, and in particular to a kind of waterborne flame retardant damping paint.
Background technique
Damping paint type is more both at home and abroad at present, but has solvent type and aqueous type two from the solvent of coating to be divided to mainly
Kind.The former contains organic solvent and pitch mostly, and toxicity is high, volatility is big, pollution environment, application property are poor, less use.Afterwards
Person's damping paint takes water as a solvent, and has the low smell of low toxicity, low cost, easily construction, the feature of environmental protection, is city rail vehicle damping paint
Preferred product.
Water paint is using water as decentralized medium asepsis environment-protecting, using high performance resin as film forming matter, using inorganic matter as filler, and property
Can be excellent, it is easy for construction.It has been widely used in locomotive rocket, engineering machinery, household electrical appliance etc..With modern industry, traffic
Transport, the development of aerospace cause and the attention to environmental protection, damping material is necessarily increasingly desirable, especially high-performance environment-friendly
The damping material of type.Current damping paint is difficult to meet requirement, has the following disadvantages：Organic solvent type damping
There is organic solvent volatilization pollution environment in material；Waterborne flame retardant damping paint damping capacity is lower, and damping temperature domain is relatively narrow；
Flame retardant property is to be improved.
In terms of damping capacity, conventional damper coating, which mainly fills film forming matter and is modified, starts with Fillers selection to improve
The damping capacity of coating.Wherein, filler usually selects sheet mica, followed by superfine graphite and common graphite.This may be piece
Shape mica increases the poly- shear deformation of filler interlayer polymer.In addition, sheet mica under the action of shear force, there is orientations
Trend, so that the friction between polymer chain and mica sheet is increased, to improve damping capacity.However, not every
Laminal filter can improve damping capacity, and wherein the graphite with glass powder of sheet but decline damping capacity.In addition, damping applies
Material is coated in metal structure surface and, its working principle is that damping paint absorbs vibration mechanical energy, can be converted with vibration and noise reducing
It dissipates at thermal energy.With the raising of the mechanical movements speed such as aircraft and track train, further serious, damping paint absorption is vibrated
The thermal energy of conversion is significantly increased.Many high molecular polymers are combustibles, do not have flame retardant property, there are fire hazards.
Summary of the invention
