Abstract
The invention discloses an anti-microbial plastic-wood floor and a preparing method thereof. The anti-microbial plastic-wood floor is a plastic-wood floor with the surface provided with a layer of nanometer titania film. The preparing method comprises the steps that the plastic-wood floor is ground, cleaned thoroughly and dried and then is immersed in prepared nanometer TiO2 sol for 10-30 min, the plastic-wood floor is taken out and dried, and then the anti-microbial plastic-wood floor is obtained. By means of the anti-microbial plastic-wood floor, formaldehyde produced by new building materials, bonding agents and the like in a room, acetaldehyde produced by smoking, methyl mercaptan produced by household dust and the like and other organic peculiar smells can be decomposed and removed under ultraviolet irradiation, the surface contamination of greasy dirt and organic matter can be decomposed, and the ecological natural environment is facilitated for a long term.
Description
Technical field
The present invention relates to plastic-wood floor sheet material and preparation method technical field, specifically a kind of antibacterial plastic-wood floor and its

Background technology
At present, in house ornamentation ornament materials there be much the species on floor, mainly has by materials classification：Solid wooden floor board, reinforcing are multiple
Conjunction timber floor, solid wooden compound floor, bamboo-wood floor, cork flooring etc., but either solid wooden floor board, composite floor board or bamboo and wood
Floor is all non-moistureproof, and water breakthrough is just easily swollen causes deformation, is gone mouldy using all existing for a long time where humidity is changed greatly
The problems such as.At present, house ornamentation market occurs in that novel floor material --- plastic-wood floor, it has the Waterproof corrosion and wood of plastics concurrently
The texture of material, service life can reach more than 10 years, be not likely to produce crackle, not fugitive color, will not moisture absorption and deformation, but when modeling wood in
Organic fiber exceed it is a certain amount of when, also can be attacked by mycete, i.e., mildew or mildew etc. occurs in floor surface.
The content of the invention
The purpose of the present invention is for above-mentioned deficiency of the prior art, there is provided a kind of antibacterial plastic-wood floor, the antibacterial modeling
Also imitate with significant sterilizing function and antibacterial decontamination in addition to the existing characteristic of general plastic-wood floor on timber floor floor
Really.
It is a further object of the present invention to provide the preparation method of above-mentioned antibacterial plastic-wood floor, the preparation method process is simple,
Effect is significant, it is adaptable to industrialized production.
The purpose of the present invention is achieved through the following technical solutions：
There is one layer of nanometer two on a kind of antibacterial plastic-wood floor, including plastic-wood floor base material, the surface of the plastic-wood floor base material
Thin film of titanium oxide.The nano-titanium dioxide film thickness is 20-150 microns；The plastic-wood floor base material is generally hollow four
Hole plastic-wood floor.
The preparation method of above-mentioned antibacterial plastic-wood floor includes step in detail below：
（1）, plastic-wood floor base material of slightly being polished with sand paper, after with ethanol substrate surface is scrubbed, dry in an oven
It is dry stand-by；The temperature of baking oven is typically set in 70 DEG C -80 DEG C.
（2）, by butyl titanate and dehydrated alcohol by volume be 1:4-1:8 ratio mixing, and add inhibitor acetyl
Acetone, acetylacetone,2,4-pentanedione is 2 with the volume ratio of butyl titanate:5, stir, solution A is obtained, it is stand-by；Dehydrated alcohol 68% is dense
Degree nitric acid is with deionized water according to volume ratio 20:2:5 are mixed, and adjust pH=3-4, and 15-30 min are stirred at room temperature, and obtain molten
Liquid B, solution A is placed in 50 DEG C of -70 DEG C of constant water bath box, and solution B is slowly added in solution A, stirs 2-4h, obtains nanometer
TiO2 colloidal sols；
（3）, plastic-wood floor immersed and soak in nano-TiO2 hydrosol obtained in step 2 10-30 min, take out in atmosphere
After drying 1-3h, continue to dry 2-4h in an oven, obtain the antibacterial plastic-wood floor that nano TiO 2 inoranic membrane is wrapped up on surface.
In further design, the whipping process in step 2 is stirred using magnetic stirrer, and mixing speed is
150-180 r/min。
In further design, the temperature of baking oven is set in 80 DEG C -100 DEG C in step 3.
The present invention has beneficial effect following prominent：.
The present invention has compared to existing technology advantages below：The light that this patent has using nano titanium oxide (TiO2)
Catalysis is utilized, and catalytic decomposition moulds the antibacterial of wood surface and pollutant, with high catalytic activity, good chemical stability, without two
The features such as secondary pollution, nonirritant, safety non-toxic, can not only be by formaldehyde, the smoking produced by new building materials, binding agent etc. in room
Organic abnormal flavour such as the methanthiol of the generations such as acetaldehyde, the domestic dust of generation decomposes under ultraviolet irradiation and eliminates, moreover it is possible to point
The surface contamination of solution greasy dirt and Organic substance, long term beneficial is in ecological natural environment.
