Description
Technical field
The invention belongs to field of surface coatings, more particularly to a kind of to purify the strong attaching surface polymer layer of air.
Background technology
Room air pollution has become one of the principal element for threatening human health.
Photo-curing material is mainly made of light-cured resin, reactive diluent and photoinitiator.Photoinitiator refers in light
Under the action of can excite for free radical or cation a kind of compound, the optical physics of photoinitiator, photochemistry property confrontation light
Initiation, the control of photopolymerization reaction process are extremely important.
As soon as China is a country for cancer high incidence, almost there are one cancer patients to occur within five minutes, according to a large amount of
Research report, the toxic and harmful gas that interior decoration, furniture, electric appliance generate are the main reason for currently the majority cancer induce,
Modern almost 80 ~ 90% time spend indoors, the quality of room air is but toxic concerning people's health
The involuntary health for destroying us of pernicious gas.It is a kind of effective means wherein to close and be harmful to gas source.
Photo catalyst TiO_2 is one of the effective means for the indoor available gas of removal being currently known.But its actual application
In there are many limitations.For example, how TiO2 to be effectively dispersed in indoor environment, how to prevent nanosized TiO_2 to the mankind
The potential hazard of health.And the effective solution of the present invention above problem.
Invention content
The method that the present invention provides a kind of to prepare the strong adhering coating of air purification on inorganic or organic substrate surface, should
Method can effective being fixed on nano TiO 2 strength on the surface of building materials or finishing material, and form polymer on surface
Film obstructs concentration and decomposes indoor harmful gas, to achieve the purpose that purify air.
The present invention provides a kind of methods prepared by purification air surface coating, including：A) in inorganic or organic substrate
Pre-processed on surface, b) mixed solution of photoinitiator and polymerisable monomer is applied on inorganic or organic substrate, it is micro-
After light irradiation ventilation a period of time, its surface is made to form the undried sticky layer of one layer of 10 ~ 100um, c) in layer sticky in this way
Upper spraying TiO2 disperses solution, d）Coating is cured and dried by UV/VIS radiation or electron beam.
Pretreatment can be to polish, washing, and alkali cleaning and other common methods remove dust and grease.
Mixed solution can be used with solution, suspension or emulsion form.
Photoinitiator is preferably following compound：Benzoin, benzil ketals, acetophenone, hydroxyalkyl
Phenyl ketone, borate, triazine, diimidazole, polysilane and dyestuff, and corresponding coinitiator and/or sensitizer.
Without crosslinked photoinitiator, monomer by being removed with solvent and/or water and/or mechanical treatment after step d)
It goes.
The method of application includes spraying, dipping, coating and other common methods.
Wherein TiO2 is the nano TiO 2 of grain size 10nm.
Light stabilizer, free radical scavenger or visible colorant can be also added in the mixed solution of application.
Specific embodiment
Pretreatment purpose is carried out on inorganic or organic substrate surface is that removing influence polymeric layer is adhered to surface
On the substances such as grease.
Used photoinitiator can be common photoinitiator, including radical photoinitiator and cationic light
Initiator.Radical photoinitiator mainly has benzoin ethers (styrax ethers), benzil ketals class, acetophenones, sulphur
Miscellaneous anthrone class, benzophenone and aminated compounds；Cationic photoinitiator mainly has aromatic diazo salt, aromatic sulfonium salts and iodine
Salt, ferrocene salt, organic aluminium compound/silane systems.
Low-light irradiation refers to being irradiated with faint UV light, and reactive moieties is made to carry out but not exclusively.Irradiation time is usually 15
Minute.
Polymerized monomer includes the monomer of the linear chain or branched chain with unsaturated group.It is preferred that the Yi Beiguang of environmental sound
Initiator causes the alkenyl class monomer of polymerization, such as 1,6- hexanediyl esters.
The mixed solution that polymerized monomer and photoinitiator solvent are formed is applied by a certain concentration on substrate surface, in nothing
It is dry to the sticky layer for forming 10-100um under the conditions of light.Inventor has found after forming the sticky layer of the thickness, is subsequently being easy
It realizes that the strong of polymeric layer is adhered on substrate surface, and nano TiO 2 in nano TiO 2 solution is contributed to incorporate polymer
Layer, and assemble and play degradation on the surface.The sticky preferred 20-80um of layer, more preferable 50um.Too thin polymeric layer is not easy
In fixed TiO2 particles and it is easy breakage, too thick polymer layer can make TiO2 particles cladding wherein, not play degradation.
The step of illumination curing polymeric layer, is happened at after application nano TiO 2 solution, this may be implemented to fix TiO2
It will not be peeled off compared with conventional method in the effect of polymerization layer surface, to avoid its genotoxic potential to human body.TiO2's
The preferred 10nm of average grain diameter, because the TiO2 of the grain size has the function of better degradation and is fixed on surface.
