Description
Technical field
The present invention relates to a kind of dumb light thixotropic coatings.
Background technique
Metal oxide, especially silica have been added into certain coating materials, with the effect of realization " dumb light "
Fruit.Apply wet film on base material be at the beginning under the action of surface tension it is flat, to form smooth surface.With film
Drying and curing, viscoplasticity caused by Sol-gel phase transition increases, hinders particle and enter film, surface deformation is to adapt to
Duller particle.The characteristics of this roughness remains unchanged in cured film, cured film is matte management.Due to certain metal oxygens
The photoextinction of compound, especially porous silicon, produces ideal surface effect in some applications, and ideal formulation for coating material
The performance that should have other additional, such as a degree of thixotropy, to enhance its practicability in various applications.
Thixotropy is a characteristic of formulation for coating material, it is related with the viscosity of coating.In fact, as formulation for coating material becomes
More thixotroping, the sagging behavior of coating become less obvious.For certain applications it is necessary to a kind of tipping resistant coating composition, with to the greatest extent
Amount reduce coating drip in application process, sagging and sagging.In terms of improving formulation for coating material thixotropic property, previous trial makes
With many additives, such as modified resin and metal oxide.
Silica is one kind with silica (SiO2) be basic structural unit inorganic material, in many business applications
In it is all very useful.Silicon exists with molecular species, such as monomer, dimer, oligomer, ring-like and polymer.In addition, dioxy
SiClx can be amorphous, is crystal, aquation, solvation or drying, and can be with various particles and aggregation shape
State exists.
Amorphous silica can precipitate to be formed by molecule, for example, unsaturated by cooling supersaturated solution, concentration
Solution, or silica precursor (such as SiCl for passing through careful hydrolytically unstable4Solution, esters of silicon acis, (SiOR4) etc.), Si is provided
(OH)4Supersaturated solution, from amorphous silica is wherein precipitated.
Thermal origin or " fumed silica ", usual partial size in 2-20 ran, are formed by gas phase.For example, silicon
(usually sand) can be vaporized at 2000 DEG C or so.Anhydrous amorphous silicon particle is formed after cooling.In addition, silica can also be
1500 DEG C or so distillations.SiO is formed in the presence of reducing agent (such as coke), SiO can be oxidized to form particulate silica.It is raw
The other methods for producing fumed silica include, for example, aoxidizing SiCl at high temperature4Or it burns in the case where having methane or hydrogen
SiCl4。
Silicon dioxde solution has polymerization behavior, and Si-O-Si key is caused to increase, and Si-OH key is reduced.In an aqueous medium, non-
Crystal silicon dissolves (and/or depolymerization), is formed Si (OH)4.By polymerization, being formed in particle surface has internal Si-O-Si key and outer
The discrete particle of portion's Si-OH key.Under certain conditions, the polymerized silica silicon particle being consequently formed will be further combined with formation
The chain and network being made of individual particle.
Under normal circumstances, under neutral or basic conditions (pH >=7), the size of particle tends to increase, and quantity tends to reduce,
And in acid condition (pH < 7), the trend of particle aggregation cluster is larger, ultimately forms three-dimensional network.The presence of salt can be reduced
Interparticle electrostatic repulsion makes particle be easier to assemble under neutral or basic conditions.
" colloidal sol " word refers to the colloidal solid of dispersion, such as the dispersion of amorphous silica in an aqueous medium.Such as
Fruit colloidal sol be it is stable, even across storage in several years, will not gel or precipitation, and dioxide-containing silica can reach 50% left side
The right side, particle diameter is up to 300nm or so, although particle is greater than viscosity of the sinking speed depending on medium after 70nm.For example, dioxy
SiClx colloidal sol can be by making particle increase to a certain size, or in sodium silicate solution (Na in weakly alkaline solution2SiO3) in
Diluted acid is added, quickly mixes, until pH is down to 8-10 or so, then removes Na+(for example, ion exchange resin or electroosmose process)
And it is formed.Silica solution, depending on the type of silicon, the property of granular size and particle can be in the condition of faintly acid to highly acid
Lower shakiness is shaped as gel.
" gel " word refers to coherent, the rigidity, continuous three-dimensional network being made of colloidal solid.Silica hydrogel can lead to
The aggregation (usually without in and under the acid condition of salt) of colloidal silica particles is crossed to form the microcosmic knot of three dimensional gel
Structure.However, whether gel can form the property depending on silica under given conditions, for example, granular size and particle
The property on surface.
" hydrogel " refers to a kind of gel, and hole (space of gel microstructure portion) therein is filled by water.It is similar
Ground, " alcogel " word refer to the gel that alcohol is full of in pore.When gel drying forms desiccant gel, evaporation be will lead to
Gel largely collapses, so that generate relative high density collapses powder.On the contrary, when gel is obtained sufficiently by gel microstructure
When the mode of protection is dry, a kind of desiccant gel of low-density is formed, referred to as " aeroge ".Silica aerogel may have very not
Ordinary and ideal characteristic, for example, optical clarity, extremely low density and unprecedented low thermal conductivity.
Synthesize silicon, for example, micronization silica xerogel and sediment as delustering agent, due to silicon particle surface
There are silanol groups, usually hydrophilic.It is well known that this silicate to coating almost without thixotropy, result even in
Other are ineffective for thixotropic additive.
By consulting domestic and foreign literature, it is thus understood that foreign countries have already passed through a variety of trials at present, by modifying the structure of silica gel,
A kind of effective delustering agent is become, but very little is influenced on thixotropy.U.S.'s pa is special.No. 5221337 disclose it is organic more
First alcoholic compound can produce the delustering agent to formulation for coating material thixotropy almost without negative effect to the modification of silica.So
And this method still has problem, because adding thixotropy additive and delustering agent simultaneously can cause not in formulation for coating material
Good interaction.
Therefore, there is still a need for a kind of formulation for coating material, this formula had both shown improved disappear when being applied to various matrixes
Light effect, and show thixotropic effects.
