With the special nano-structure of the hollow nano-grade silica particles, heat insulation of the heat-insulation paint is greatly improved.
Description
Technical field
The present invention relates to the preparation of a kind of hollow nano-silicon dioxide particle and insulating mold coating thereof, have efficient thermal and insulating performance, belong to the energy-saving coatings technical field.
Background technology
Saving energy and reduce the cost, increasing economic efficiency is one of elementary object of scientific research and technological development, and coating technology is no exception.Behind 20 century 70s, world climate warms, and earth energy is increasingly exhausted, and in all structure of energy consumption ratios, building energy consumption surpasses 1/3rd, and proportion is maximum; In addition, required in industrial production to reach energy-saving and cost-reducing place by Insulation equally also very many, and therefore, exploitation heat insulation heat preservation energy-saving coating has great realistic meaning.Insulating mold coating combines the dual nature of coating and thermal insulation material, have many good qualities, simple such as coating producing process, thermal conductivity is low, high insulating effect, construction are relatively simple, be specially adapted to the insulation of the insoluble special-shaped equipment of lagging material etc.But existing insulating mold coating mainly is to have adopted the materials such as common hollow beads, titanium dioxide, and their particle diameter mostly is greatly about 15 μ m, and is that have even higher, and the effect of heat insulation that therefore plays is limited, and effect of heat insulation is in urgent need to be improved.
Summary of the invention
The objective of the invention is to prepare a kind of nano level hollow silica particle, the particle diameter of this silicon dioxide granule is below 100nm, because the special-effect of nanoparticle, hot gas flow within it section is difficult to conduction, therefore adopts the heat-proof quality of the insulating mold coating that nano-silicon dioxide particle makes to be improved greatly.
Its mentality of designing is: prepare nano level hollow silica particle, and make thermal insulation coatings with this hollow silica, to improve the effect of heat insulating.The key step of this hollow nano-silicon dioxide particle preparation: (1) coats layer of silicon dioxide at its skin take certain nano level material as template under the condition of fully disperseing; (2) template is removed under hot conditions, got final product to get the hollow nano-silicon dioxide particle.
Technical scheme of the present invention: the preparation process of a kind of hollow nano-silicon dioxide particle and insulating mold coating thereof is:
(1) preparation of hollow nano-silicon dioxide particle: take nano pipe/polyhenylethylene or vesica or organic expander as template, add in the flask, add 20-60mL ethanol, 20-60mL water, 1-5mL ammoniacal liquor, 0.1-0.5g cetyl trimethylammonium bromide or palmityl trimethyl ammonium chloride, add surfactant polyethylene 2000 or Sodium dodecylbenzene sulfonate 0.1-0.5g, 1-5mL silicon source, stirring reaction 2-10h under 30-90 ℃ of condition, the taking-up product is centrifugal, washing, under 300-900 ℃ condition, calcine after dry, namely obtain particle integrity, pattern is the hollow nano-silicon dioxide particle preferably.
Wherein adding surfactant polyethylene 2000 or Sodium dodecylbenzene sulfonate is for nano-form is fully disperseed, and at its surface formation skim, increase template to the adsorptive power in silicon source, to improve the productive rate of hollow nano particle, can greatly reduce silicon and be derived from the probability that figure becomes solid particle.Wherein control add-on, kinds of surfactants and the addition in silicon source, particle diameter, the wall thickness that the length in reaction times can be controlled the hollow nanoparticle, obtain the hollow nanoparticle of not cracky, uniform particle diameter, stable performance.
(2) preparation of insulating mold coating: hollow silica particle and the fillers such as titanium dioxide, perlite of preparation are added in the film forming matter, and it is some to add wetting dispersing agent, defoamer, flow agent etc., makes insulating mold coating.Its prescription is as follows:
Film forming matter: 30～45 parts
Hollow nano-silicon dioxide particle: 4～10 parts
Titanium dioxide: 2～4 parts
Pearlstone: 2～4 parts
Deionized water: 36～62 parts
Defoamer, dispersion agent, flow agent etc.: some
Beneficial effect of the present invention:
(1) by preparation hollow nano-silicon dioxide particle, just can obtain the better insulating mold coating of effect of heat insulation.The particle diameter of this hollow silica particle is very little, can effectively stop the heat conduction of section within it, has improved widely the heat insulation performance of thermal-insulation coating; And the present invention selected tensio-active agent, formed a skim on its surface, increased the adsorptive power of template to the silicon source, greatly increased the yield of hollow nanoparticle.
(2) intensity of this hollow nano-silicon dioxide particle is large, with the stirring of film forming matter in can be damaged, performance is very stable.
(3) construction technology is simple, and the duration is short, saves cost.
