According to the invention, the structure is stable, and a biomass film-forming matter is used as a sealing agent to prevent free pollutants of furniture from continuously releasing towards the inside of a room, so that the pollution source at home is controlled; the nanometer powder substance is stable in structure, does not expand, has a large specific surface area, high ion-exchange capacity and big micropore diameter, can effectively adsorb pollutants on the surface of a reaction film, and blocks the pollution releasing pathway; an efficient plant extract formaldehyde catching agent reacts with free formaldehyde released from furniture on the interface of a film, so that pollution is radically eliminated; the nanometer powder contains a negative ion functional material and a photocatalyst, can release out negative ions, and can decompose adsorbed pollutants.
Description
Technical field
The present invention relates to a kind of film, specifically a kind of preparation method of biomass screen depressant prescription.
Background technology
Nanoparticle is subject to the favor of countries in the world because of its novel unique character.Nearest more than ten years achieve develop rapidly.Select the nano material of difference in functionality can prepare a series of multi-functional, high performance nano combined film with miscellaneous polymkeric substance by appropriate mating.Thus be widely used in the numerous areas such as building, woodenware and automobile film.
UV film environmental pollution is little, and curing speed is fast, saves the energy.Be different from that traditional film is volatile, curing speed is slow, therefore, UV film became the main substitute of traditional film in recent years.Nano TiO 2 can absorb ultraviolet, can reflect again, scatters ultraviolet, can also, through visible ray, be the ultraviolet protecting agent of superior performance, extremely rising physical shielding type.The irradiation of light can cause TiO2 surface to form wetting ability and marvellous super amphiphilic of lipophilicity two-phase coexistent in nano-area.As the nano-antibacterial powder of domestic suitability for industrialized production is used in film, nano-disinfection film can be obtained, be coated on building material product, as between sanitary ware, the interior space, apparatus, hospital surgical and the metope in ward, ground etc., play sterilization, the effect of keeping a public place clean.Nano TiO 2 particles, under wavelength is less than the illumination of 400nm, can absorb the short wavelength light radiation higher than its energy gap, produces transition of electron, make valence-band electrons be excited to conduction band, and form electron-hole pair, transfer energy to surrounding medium, induction photochemical reacts, thus has photocatalysis performance.
Experiment shows, nano silicon reduces the intensity that ultraviolet light polymerization film absorbs UV irradiation, thus reduces the curing speed of photocuring film, but can significantly improve hardness and the sticking power of ultraviolet light polymerization film.
Current, domestic top-grade furniture generally uses traditional film and spraying method, its environmental protection, transparence and wear resisting property hold concurrently in varying degrees exist be difficult to break through bottleneck.This and traditional paint, namely the self attributes of polyurethane PU, unsaturated polyester PE has indivisible relation.Current furniture paint on the market generally makees priming paint with PE, and PU does finish paint to reach smooth, the high saturating effect of furniture surface.But when these two kinds paint use, PE need allocate initiator and promotor, and PU need allocate thinner, has material harmful in a large number in its composition, as benzene,toluene,xylene, formaldehyde, vinylbenzene etc., is unfavorable for ecotope.
