Abstract
The invention belongs to the field of building paint and discloses a phase transition thermal storage microcapsule paint mixed with micron order copper powder in order to improve the thermal properties of phase change thermal storage microcapsule paint, and with self-cleaning, heat preservation and temperature control effects. The microcapsule uses tetradecyl alcohol as a capsule core, and melamine and formaldehyde as a capsule wall. During the package of the microcapsule core by the capsule wall, an appropriate amount of the micron order copper powder is added at an appropriate rate, so that the copper powder is attached to or embedded in the microcapsules to increase enthalpy of phase change by 50J / g. The employed paint is not intermiscible with the microcapsule wall and has self-cleaning efficacy.
Description
Technical field:
The present invention relates to a kind of building coating field, be that a kind of mixing adds Micron-Sized Copper Powders Coated to improve the phase-change thermal storage enteric coating of heat conductivility, there is effect of self-cleaning insulation temperature control.
Background technology:
At present there is microcapsulary, but fail good to be applied to indoor paint field, because microcapsulary immature and need to overcome the impact of coating on properties of microcapsules.Current water-borne coatings makes good, especially the building coating based on water-borne coatings accounts for about 38% in China's coating total amount, and the cyst wall of described formulation for coating material and microcapsule does not dissolve each other, effect that microcapsule have storage and discharge latent heat of phase change can be fully played, therefore fully microcapsule can be applied to water-borne coatings field ripe already.
The deficiency of the research field of current microcapsule is latent heats of phase change of raising microcapsule that cannot be good, because the hybridization of cyst wall and capsule-core, and the obstruction that cyst wall passes to capsule-core latent heat, actual transformation latent heat generally reduces 20-50J/g than calculated value, microcapsulary that the present invention adopts encapsulating phase change material tetradecyl alcohol stores and release latent heat of phase change, simultaneously by adding heat conduction effect that appropriate Micron-Sized Copper Powders Coated substantially increases microcapsule under certain rotating speed.The actual transformation latent heat of microcapsule is made to improve about 50J/g.
Summary of the invention:
The invention provides the mixture of a kind of coating and microcapsule, described coating can well and the latent heat of phase change of effective release microcapsule.Object is to solve the bottleneck that current phase-change thermal storage microcapsule institute runs into, namely latent heat of phase change is little and be difficult to be improved by the control of rotating speed and drop rate, and reason is that microcapsule organism cyst wall pair wraps up with the capsule-core as phase change material makes it be difficult to carry out good heat conduction.
The present invention adds Micron-Sized Copper Powders Coated when effect microcapsule wall parcel capsule-core with suitable speed and consumption, makes copper powder adhere to or be partially submerged into microcapsule, improves the heat conductivility of microcapsule.Through the good heat conductive of copper powder, detect through DSC, the enthalpy of phase change recorded improves 50J/g.And the form of microcapsule and encapsulation rate can not be affected.
Formulation for coating material of the present invention, can overcome microcapsule and water-borne coatings and to mix this problem, the organic components such as various auxiliary agent of coating itself may carry out dissolving each other with the composition of microcapsule thus affect the encapsulating performance of microcapsule outer wall.Formulation for coating material of the present invention does not have mutual solubility with the composition of microcapsule, and microcapsule are scattered in coating, still can play good heat conduction heat accumulation heat release effect.
The present invention is used for interior wall and has good indoor temperature control effect, in certain temperature range, (20-25 DEG C) carries out phase transformation, and the phase change material of microcapsule inside when low temperature heats up can liquefy thus heat release, otherwise, when lowering the temperature from high temperature, can solidify in this temperature field thus absorb heat.Thus reduce the vibration frequency of room temp, be close with the body sense comfort level of human body, also play effect that household is energy-conservation.
What the microcapsule in the present invention adopted is situ aggregation method, monomer in situ aggregation method and catalyzer are all positioned at the outside or inside of capsule-core, and require monomer-soluble, generation polymkeric substance soluble, polymer deposition capsule-core surface and coated formation microcapsule.Before polymerization reaction take place, capsule-core must be dispersed into particulate.Become shell material can be water-soluble or oil-soluble monomer, can be the mixture of several monomer, also can be water-soluble low molecular weight polymkeric substance or prepolymer.
