Description
Technical field
The present invention relates to nanometer titanium dioxide silicon coating, be coated in the effect that glass and building surface have waterproof, anti-scratch and protection surface.
Background technology
Nano particle has larger specific surface area and higher surfactivity, after mixed with polymers, the physics that easy generation is stronger or chemical action, play the effect increasing mixture hardness and intensity, compensate for again nano particle self weak shortcoming relative to stromal surface bonding force simultaneously.Therefore, nano particle is widely used in the middle of the modification of polymkeric substance.But due to the polarity relative mistake of polymkeric substance, make the consistency of nanometer silicon dioxide particle and polymkeric substance poor, nano particle is easily reunited and have impact on modified effect.
The coupling agent containing silane is mainly adopted to carry out modification to increase the common capacitive of nano particle and polymkeric substance to nanoparticle surface at present.CN200910088026.5 has set forth with nanometer silicon dioxide particle by extrusion moulding Noryl; CN201210230325.X have employed coupling agent and between nano silicon and polymkeric substance, introduces chemical bond to increase common capacitive, then carrys out further modified epoxy with this material; CN200680013072.3 adopts silicon-dioxide to produce specialty elastomer by high temperature; The open Nano composite automotive topcoat of CN201310190567.5, adopts nano silicon to do to provide anti-aging and mechanical property, comprises titanate coupling agent, carry out the reactive force between enhancement component in component; CN201110215930.5 provides hydrophobic nano composite automobile finish, is distributed to by nano silicon in polyacrylic acid; The dispersion agent with reactive group is employed in dispersion process; CN200610117309.4 discloses nano-particle reinforcement urethane, and employs melamine class linking agent; CN201010524511.5 has set forth the preparation method of nano silicon/polyacrylate dispersion, and the coupling agent added containing siloxanes is to increase the reactive force between each component; CN03117780.8 discloses the preparation method of polyacrylate/silicon dioxide composite particle, employs the coupling agent such as silane coupling agent, titanate coupling agent in patent.
Above-mentioned patent all uses coupling agent in use nanometer silicon dioxide particle process, or needs pyroreaction, or needs multistep production technique, complex process, and inevitably form chemical bond due to coupling agent, produce chemically crosslinked structure, make coating remove difficulty from stromal surface.
Therefore, be badly in need of a kind of nano silicon/polymer coating of exploitation, production technique is simple, formulation stable, and hardness is high, and bonding force is strong, and does not add any coupling agent or linking agent.
Summary of the invention
The present invention have developed a kind of the energy various surface of widespread use, especially automobile, glass and frosting, protection surface, and waterproof is strong with surface adhesion force, easy to use, removes conveniently.
The invention provides a kind of nano silicon/containing poly-(methyl) acrylate paint of alcoholic extract hydroxyl group, it is characterized in that this coating comprises following component:
Nanometer silicon dioxide particle comes from silicon dioxide gel, is the combination of one or more without ionic silicon sol, acidic silicasol, alcohols silicon sol or the composite silica colloidal sol based on silicon, preferably without ionic silicon sol and alcohols silicon sol;
Containing poly-(methyl) acrylate of alcoholic extract hydroxyl group as shown in structural formula I:
Wherein R is ethylidene, propylidene, or butylidene, preferred ethylidene and propylidene, most preferably ethylidene; R
1for methyl, ethyl, propyl group, butyl or hexyl, preferred ethyl and propyl group, most preferably ethyl; R
2and R
3for hydrogen or methyl, preferred hydrogen; M is the integer between 10-200, and n is the integer between 200-4000, m/n between 5-35%, preferred 5-25%; The above-mentioned alcoholic extract hydroxyl group that contains gathers the consumption of (methyl) acrylate between 1-15 quality %, preferred 5-15 quality %;
Essence is oil soluble industry essence, and consumption is 0.1-1 quality %;
Solvent is methyl alcohol, ethanol, Virahol, propyl alcohol, butanols, propylene glycol, one or more mixtures of acetone or butylacetate; Wherein preferred alcohol and Virahol.
The preparation method of nano silicon disclosed by the invention/containing poly-(methyl) acrylate paint of alcoholic extract hydroxyl group is as follows: first adopt solution method synthesis containing poly-(methyl) acrylate of alcoholic extract hydroxyl group, then add appropriate silicon sol, essence and solvent and namely obtain successfully.Nano silicon/gather the preparation technology of (methyl) acrylate paint simply containing alcoholic extract hydroxyl group, do not use coupling agent or linking agent, coating standing storage is stablized, and hardness is high, lastingly bonding, and waterproof and in the future removing are easily.Know-why is in solvent evaporates process, and silicon sol for the nucleus of condensation are assembled, substantially increases the reactive force of nano SiO 2 particle and polymkeric substance with the polarity alcoholic extract hydroxyl group in polymkeric substance; Because there is no chemical bond between polymkeric substance and nano silicon, make formed coating can be swelling by alcohol organic solvent, thoroughly removed.
