Description
Technical field
The design paint field of the present invention is related to temperature and changes the coating of color.
Background technology
At present, the electrochromic substance in allochroic paint is generally added to the formulation for coating material of resin composition in the form of microcapsules
In, pass through temperature or illumination variation so that physics or chemical change occur for the off-color material in capsule, so as to which paint film be made to be in
Existing different color, referred to as allochroic paint.Due to coating in film forming procedure along with resin solidification crosslinking and solvent
Volatilization, resin crosslinked has different degrees of contraction, and along with such contraction, the discoloration microcapsules in formulation for coating material will
By pressure break, so as to cause the destruction of allochroic paint colour change function.On the other hand, either common coating or allochroic paint, one
As organic solvent or chemical emulsifier containing volatilization, all can be organic molten during coating application and later stage film harden
Agent or the discharge of emulsifier, cause environmental pollution.
It is learnt from presently disclosed allochroic paint factory formula, the resin that is used from coating divides, and is divided into solvent type discoloration
Coating and aqueous allochroic paint.Wherein solvent based coating uses oil-soluble resin, contains in formula and is not involved in the organic molten of reaction
Agent, organic solvent (VOC) can be evaporate into air during the drying and consolidating of coating, cause atmosphere pollution, welding.Water
Property coating use water-base resin, although without the discharge of VOC, containing being useful for the emulsifiers of emulsifying resins in formula, though
So itself and it is non-volatile, but it is also a kind of organic matter for being not involved in crosslinking coatings curing reaction, exposes to the sun and rain or grows
Phase is exposed in air, this emulsifier can slowly separate out, equally cause environmental pollution.
Invention content
For contraction of the coating in the solidification process that forms a film and the discharge of organic solvent, the present invention is molten using response type
The shortcomings that agent and resistance contracting agent are added in coating system, overcome traditional allochroic paint, reaches and beautifies the environment, energy saving
