Shape hollow material, applies and can improve corrosion resistance, weatherability and the heat-proof quality of coating and the heat conduction of insulation material in coating
Coefficient, with the increase of hollow glass micropearl content, heat conductivity is lower, and hollow glass micropearl can also improve coating simultaneously
Reflectance, can be using hollow glass micropearl as filler, and the bottom using solar heat reflection paint coating (is connect with coated article
Touch) in.
Hollow glass micropearl is applied in coating, after coating is dried, hollow beads close-packed arrays get up, and form one
Complete hollow sealing coat, not only has good effect of heat insulation, also has excellent soundproof effect.But, hollow glass is micro-
Pearl true density is only 250～400kg/m3, it is directly added in aqueous coating system, floated over coating on hollow glass micropearl is easy
Surface forms conjunctiva and reduces the uniformity of coating.Therefore, realize it in painting by hollow glass micropearl surface is carried out with modification
Dispersed in material system, it is currently to realize one of effective ways of hollow glass micropearl application and its functionalization.
TiO2It is most widely used a kind of important pigment in coating, hardly react with other materials under its room temperature, no
It is dissolved in water, fat, is also insoluble in acid, alkali, the excellent weatherability of coating and glossiness can be given.Early in the nineties in last century,
Scientist just has been proven that nano-TiO2There is photocatalysis characteristic, that is, under light action, nano-TiO2Can occur continuously to aoxidize
Reduction reaction, final organic pollution is CO by solving2And water.
In cenosphere surface attached last layer TiO2Thin film, so can improve the whiteness of hollow glass micropearl.In addition TiO2
Thin film is high to the reflectivity of sunlight, can play reflected sunlight, this makes it possible to increase the usage amount of hollow glass micropearl, carries
Its heat insulation and heat control ability high.
Using butyl titanate as forerunner, butyl titanate has very high chemism to water, and hydrolysis generates TiO2With positive four
Butanoic acid.Hydrolysis product is nontoxic, easily removes with calcining through being dried.
From dehydrated alcohol as solvent, because butyl titanate has very high chemism to water, need water content pole
Low solvent, dehydrated alcohol is in organic solvent now using the widest and convenient sources, low price, readily volatilized, nontoxic.
Glacial acetic acid does inhibitor, adds glacial acetic acid to adjust the pH of hydrolysis, can suppress the hydrolysis speed of butyl titanate
Degree, makes reaction slowly carry out, and generates uniform colloidal sol.
Described TiO2Coated hollow glass bead is prepared by following steps：
(1) measure 25-30ml dehydrated alcohol and 8-10ml butyl titanate is added in there-necked flask, in temperature 26-30 DEG C
Under the conditions of, turned with rotating speed 1800-1900/min stirring 8-10min is to uniform；
(2) add 2-3ml glacial acetic acid in there-necked flask, stir, add 8-10ml cenosphere, in temperature
Under the conditions of 26-30 DEG C ,/min is turned with rotating speed 1800-1900, stirring 18-20min is to uniform；
(3) it is added in separatory funnel after 25-30ml dehydrated alcohol and 3-5ml water being mixed in beaker, in temperature 26-
Under the conditions of 30 DEG C, it is slowly dropped in there-necked flask, time for adding is 15-20min；
(4)/min, stirring reaction 1h are turned with rotating speed 1800-1900；
(5), after standing 24-48h, product is put in 90-100 DEG C of baking oven and dries；

The present invention adopts sol-gal process to prepare TiO2Coated hollow glass bead, the preparation of colloidal sol is the key of technology,
The quality of colloidal sol directly influences the performance of final resulting materials, and the colloidal sol therefore how preparing satisfaction requirement is research emphasis.
1) amount of water：The addition of water be less than stoichiometrically consumption required for relation when, with the increase of rate of water added,
The time of colloidal sol can be gradually shortened, and when exceeding stoichiometric relationship aequum, aerosol time can gradually increase again, if this is because
When adding the water yield few, hydrolysis of alkoxide speed relatively extends aerosol time slowly；If amount of water is more than stoichiometry, solution is to dilute
Release, solution viscosity declines and makes plastic difficult, when stoichiometrically adding, the quality of plastic is good, and gelation time is relatively short.
2) rate of addition of water：Water hydrolysis solidification in the easy absorption air of alkoxide, therefore in Deca alkoxide solution, other
Observe drop rate in the case of factor is consistent, find that drop rate significantly affects aerosol time, drop rate is faster, gelation rate
Also fast, but speed easily causes that local hydrolyzes too fast soon and polymerization and gel generates precipitation, a part of sol solutionses hydrolyze simultaneously
Finally result in and cannot obtain homogeneous gel, so uniform stirring also should be aided with reaction, to ensure to obtain homogeneous gel.
3) catalyst：, as catalyst, its catalytic mechanism is different for soda acid, thus the hydrolytie polycondensation to same system, often
The different condensation polymer of generation structure, form.Research shows, the polycondensation reaction speed of acid catalytic systems is much larger than hydrolysis, water
Solution is by H3The electrophilic mechanism of O+ causes polycondensation reaction to have started to before complete hydrolysis, thus the degree of cross linking of condensation polymer is low, gained
Xerogel is transparent, compact structure；The hydrolysis of base catalysiss system are to be caused by the nucleophilic displacement of fluorine of OH-, and hydrolysis rate is more than
Nucleophilic speed, hydrolysis is relatively more complete, and the gel of formation, mainly by polycondensation reaction control, forms macromolecule polyalcohol, has higher
The degree of cross linking, the xerogel structure of gained is loose, translucent or opaque.The present invention adopts glacial acetic acid as catalyst.
4) hydrolysis temperature：Improve the temperature alkoxide favourable, low to hydrolysing activity to the hydrolysis of alkoxide, often carry out under heating
Hydrolysis, to shorten the time needed for colloidal sol preparation and gelling；But hydrolysis temperature is too high, will there is the hydrolytic polymerization of multi-products
Reaction, generates not volatile organic matter, affects gelling properties.Sometimes hydrolysis temperature also can affect the phase change of hydrolyzate,
The stability of impact colloidal sol.Therefore in the case of guaranteeing to generate colloidal sol, take lower temperature as far as possible.The present invention adopts room
Warm (28 ± 2 DEG C).
5) digestion time：The colloidal sol of tool mobility forms not flowable gel rubber system by further polycondensation reaction.Warp
In ageing, the further agglomeration of polymer becomes granule submanifold to the sol solution that polycondensation reaction is formed, and they mutually collide
Connect into big Particle Cluster, meanwhile, liquid phase is wrapped in solid skeleton and loses flowing, form gel.Ageing forms in gel process,
Ostward ripening can occur, that is, sized particles cause the increase of mean diameter because of the difference of dissolubility.Digestion time is too short,
Particle size is uneven on the contrary；Overlong time, particle growth, reunion, be difficult formed hyperfine structure it can be seen that, digestion time
Selection extremely important to the microstructure of product.
6) calcining heat：Due to nano-TiO2Its crystal formation is different at different temperature, the TiO of sol-gal process preparation2Forge
