Description
Technical field
The present invention relates to paint field, especially a kind of heat-insulated polyacrylate water paint of exterior wall and preparation method thereof.
Background technology
With the increasingly reduction of the energy such as coal, oil, natural gas, energy problem, which has become, restricts development of all countries economy
Bottleneck.According to statistics, there are about the energy consumptions of one third in building field, and the wherein building energy consumption overwhelming majority is heating and air-conditioning
Energy consumption, building energy conservation it is significant.In China, building energy conservation has more importantly meaning, because China is largely built
High energy consumption is belonged to build, and the one third of the insufficient developed country of the application of insulating moulding coating.Outer wall heat-insulating coating is in recent years
A kind of new function coating to grow up, the internal temperature of building can be reduced by being applied to the surface of building, also
Interior of building heat can be made to be not easy quickly to scatter and disappear, and it is with cheap, it is convenient to replace, construction is simple, and kind is numerous
The advantages such as more, therefore have received widespread attention.
Insulating mold coating for construction according to the difference of insulating mechanism and heat-insulated mode be divided into isolation-type insulating moulding coating, radial pattern every
Four class of hot coating, reflective insulation coating and compound insulating moulding coating.Wherein isolation-type insulating moulding coating is by being transmitted to heat
Notable resistance realize heat-insulated coating；Radiation Heat-insulated Paint is to be absorbed into a day irradiation by the form building of radiation
Line and heat are emitted to certain wavelength in air, to reach the coating of good heat-insulating cooling effect；Reflection type thermal insulation
Coating is by selecting suitable resin, metal or metal oxide color stuffing and production technology that the coating of high reflectance is made
Reflection solar heat achievees the purpose that heat-insulated；Compound insulating moulding coating is two combined according to insulating mechanism in above-mentioned heat-insulated mode
Kind is two or more to reach the coating of heat-insulated purpose.Since compound insulating moulding coating has more excellent heat insulation, because
This, researching and developing the insulating moulding coating with comprehensive performance becomes research hotspot at this stage.
Polymer emulsion is the bulk composition for preparing exterior coating, and effect is to glue various color stuffings and auxiliary agent in coating
Form an entirety, be attached to be easy to by painting substrate surface transformation be formed by curing uniformly continuous and tough and tensile protective film, be applicable in
Have in the polymer that exterior coating uses：Epoxy resin, fluorine resin, polyacrylate resin, styrene-acrylic resin etc..Polyacrylic acid
Ester is copolymerized by acrylic ester monomer, has good water resistance, alkali resistance, weatherability, light resistance and film forming
The features such as.But since polyacrylate is mostly chain linear structure, lack crosslinking points, can to form three-dimensional netted cross linking membrane,
Therefore its film is poor to the tolerance of temperature, is susceptible to " cold short heat is glutinous " phenomenon.
Chinese patent CN201710968400.5 discloses a kind of water-and acrylate composite exterior wall insulating moulding coating, raw material
Include following components by weight：20-40 parts of acrylic acid ester emulsion, 5-10 parts of titanium dioxide, 1-3 parts of hollow glass bead, silicon
9-15 parts of diatomaceous earth, 6-10 parts of ceramic hollow microballon, 3-6 parts of nano far infrared ceramic powder, ZR apply 3-6 parts of feed powder, pH adjusting agent
