    [0001] This invention involves the technical field of outdoor laminate flooring, specifically, an outdoor laminate floor and manufacturing technique thereof. BACKGROUND:
    [0002] Outdoor flooring is typically used in the public spots such as gardens, pavilions and resorts where prolonged exposure to sunlight and rain necessitates high stability, corrosion resistance and compression resistance for outdoor floors.
    [0003] Timber materials for outdoor use are integral components of building and decorative materials in China. Outdoor timber is exposed in open air for years and subject to various rigorous climates in various countries and regions, therefore, high strength, weather resistance and wear resistance are required of outdoor timber; meanwhile, easy installation and aesthetics are required as well. For a long time, outdoor timber has been dominated by natural solid hardwood, including large-size broadleaved hardwood from tropical rainforests such as African blackwood, Burmese teak wood and South American Ipe, and preservative-treated timber such as Mongolian Scots pine and Southern Yellow pine. However, the aforementioned outdoor laminate floors have the following disadvantages: (1) made of pine wood, pine floors wear poorly, susceptible to wear after long time use with costly maintenance; (2) in view of mostly outdoor use where environment changes greatly, in case of littered cigarette stubs, solid wood floors will suffer from poor flame retardancy and a low safety factor; (3) due to fast growth, pine wood is soft in quality with a multitude of knots on the timber surface where resin is largely secreted and exuded out of surface when exposed to the sunlight in the summer, which impacts aesthetics and use; (4) because of their "shrink when dry and swell when wet" property and anisotropy, harsh outdoor environment, big-amplitude and highfrequency change in moisture and temperature, and low anti-aging factor, solid wood planks are prone to substantial cracks and remarkable warping; (5) used in harsh environment, outdoor floors are prone to bores by termites and then rot, to lose value for use. DESCRIPTION OF THE INVENTION
    [0004] The present invention provides a type of outdoor laminate floor that overcame the flaws of existing techniques.
    [0005] The present invention solves technicalities by the following technical solution: a type of outdoor laminate floor comprising a substrate made from PVC foaming and wear-resistant, anti-aging covering film that is adhered to the surface of the substrate, the said covering film overlaying the surface of the substrate after being adhered by hot glue; the said covering film is modified weather-resistant polymeric film.
    [0006] Preferably, the said substrate is overall rectangular, extended with a protrusion at one end, the said protrusion being used for snap-on with the groove engineered at the other end;
    [0007] Preferably, the said covering film comprises full-covering film that completely overlays the substrate and half-covering film that overlays both end surfaces of the substrate.
    [0008] Preferably, texture patterns are set on the said substrate, the said texture patterns being set in between the end surface of the substrate and the distant end surface of the covering film to the substrate, texture patterns including wood-texture patterns.
    [0009] Preferably, the said texture patterns are set on a sticker, both end surfaces of the said sticker being individually adhered to between the substrate and the covering film by hot glue.
    [0010] Preferably, one end surface of the said covering film is coated with affinity reagent and printed with texture patterns, the distant end surface of the said texture patterns to the covering film being coated with affinity reagent and then with hot glue, the distant end of the said hot glue to the covering film (3) being coated with affinity reagent and securely affixed onto the substrate.
    [0011] Preferably, one end surface of the said covering film is coated with affinity reagent and then with hot glue, the distant end surface of the said hot glue to the covering film being coated with affinity reagent and printed with texture patterns, the distant end surface of the said texture pattern to the covering film being securely affixed onto the substrate by hot glue.
    [0012] Preferably, the said texture pattern is printed inside the covering film.
    [0013] The technique for manufacturing the said outdoor laminate floor comprises the following steps: S1: prepare standard format of board via PVC foaming, thereby forming substrate; S2: set up texture patterns; S3: apply film.
    [0014] Compared to existing techniques, the present invention possesses the following benefits:1. This invention provides a wear-resistant and anti-aging floor that features simple and compact structure and replaces solid wood with substrate and covering film, which does not only protect environment by reducing the demand for solid wood, but also leads to reduced manufacturing cost and an edge on the market, thanks to low-cost substrate and covering film; 2. In the present invention, Kleiberit adhesives are selected to tightly bond the two different materials, substrate and covering film. After long time use, the substrate and covering film will not peel off from each other, which does not only extend life of the floor but also effectively prevents the floor from warping and improves its life span by interaction between the substrate and covering film bonded together as a whole as well as reduced extensibility; 3. In the present invention, the selected covering film features superior wear-resistant and anti-aging performance, water- and moisture-resistant capability, and flame retardancy which endows outdoor floors with resistance to sunlight exposure and cigarette stub burning; protrusions and grooves engineered on outdoor floors work together to enable quick installation. 4. In the present invention, different texture patterns are set up on outdoor floors as opposed to different outdoor environments, thus allowing the present invention to apply to various outdoor spots; its strong adaptability facilitates wide adoption.
