The invention discloses a production method of a high-strength high-pressure decorating plate. Firstly various needed strengthening thermosetting resins are prepared, kraft paper is socked in the strengthening thermosetting resins for gluing, and a soaking base plate blank is obtained after soaking and drying; monochrome paper or printing paper is soaked in the prepared strengthening thermosetting resins for gluing, and pre-socking decorative paper is obtained after soaking and drying; or metal drawbench aluminum foil with the pre-gluing back serves as the decorative paper; the wood pulp kraft paper is soaked in the prepared strengthening thermosetting resins for gluing, and pre-soaking buffer paper is obtained after soaking and drying; the soaking base plate blank, the pre-soaking decorative paper and the pre-soaking buffer paper are cut, paved according to requirements of prepared decorative plates, filled in a hot press for pressing, cooling, releasing, disassembling and plate discharging after paving, and treated to obtain the high-strength high-pressure decorating plate product. By means of the technical scheme, the production method can produce the high-strength high-pressure decorating plate which is fire-resistant, water-tolerant, moisture-resistant, impact-resistant, pollution-resistant, attractive and durable.

The invention relates to a novel laminated wood. The novel laminated wood comprises a fir core veneer layer positioned at a central position, two cotton wood veneer layers which are respectively adhered on both upper and lower surfaces of the fir core veneer layer and two laminated wood layers which are adhered on the other surface of the two cotton wood veneer layers respectively, wherein the directions of wood grains of every two adjacent two veneer layers are vertical to each other. The invention also relates to a method for preparing the laminated wood. The method comprises the steps of producing the laminated wood layers, producing the cotton wood veneer layers, producing the fir core veneer layer, sizing, laminating, molding and the like. The novel laminated wood has the advantages of good stability, low cost and environment protection and can be widely used for preparing indoor decoration, such as furnitures, floors, door panels, ceilings and the like.

The invention provides a fabrication method for veneer based external wall panels. The fabrication method for the veneer based external wall panels is characterized by comprising the steps that wood veneers with the moisture content of 1-15% and the thickness of 1-3.2 mm serve as raw materials and are soaked in or coated with mixed resin modified liquid; the obtained wood veneers are dried until the moisture content is 5-15%; then three to nine layers of the dried wood veneers are assembled to plate blanks; the plate blanks are put into a relief mould for mould pressing, wherein the mould pressing hot-press temperature is 130-150 DEG C, the hot-press pressure is 1-3 MPa, and the pressing time is 1.0-1.5 minutes for every 1 mm of thickness of the plate blanks; and the pressed plate blanks are sawed into strips of a certain specification, the front faces and the side edges of the strips are coated with weather-proof waterproof paint, and then the strips are fabricated to be the outdoor purpose external wall panels with an excellent decoration effect and anticorrosion and weather-proof functions.

The invention relates to a method for manufacturing a novel material floor keel by utilizing wastes. The method is characterized by comprising the following steps: selecting 8% of attapulgite waste residue with the granularity of 80-200 meshes, 10% of fly ash, 3% of straw, 7% of mineral slag, 5% of sludge from a paper plant, 7% of waste plastic (bags) and 10% of perlite as raw materials; selecting 10% of cement, 5% of lime, 2% of talc powder and 3% of gypsum powder as auxiliary materials; selecting 2% of 50-100mm glass fiber yarn as aggregate; mixing the raw materials, the auxiliary materials and the aggregrate with 28% of magnesium chloride liquid material so as to prepare a slurry; and after mixing and soaking for 8-24 hours, stirring, discharging by a mold plate and drying, thus obtaining profile floor keel (1). The novel material manufactured by the method disclosed by the invention has the characteristics of low cost, high strength, waterproof and fireproof properties and capability of being cut and processed randomly. The novel material floor keel is of an environmentally-friendly product in the real sense.

The invention provides an ecological wooden trestle structure and a process thereof. The ecological wooden trestle structure comprises a trestle structure and a foundation structure, wherein the trestle structure is positioned above the water surface, and the foundation structure is arranged under the water surface; the foundation structure is horizontally arranged under the water surface and connected with the trestle structure through a steel-pipe post; the trestle structure comprises a square steel pipe, a wooden plate and wooden rail posts which are arranged from bottom to top in sequence; the square steel pipe is rectangular and horizontally arranged on the steel-pipe post; the wooden plate is horizontally fixed on the surface of the square steel pipe through a stainless steel self-tapping screw; the wooden rail posts are vertically embedded in the square steel pipe in an equally spaced manner and fixedly connected with each other through opposed penetration bolts; and hemp ropes are also arranged on the wooden rail posts; and the hemp ropes are suspended between the wooden rail posts and have certain radians downwards. The trestle in the ecological wooden trestle structure can be suitable for humid environments for a long time and the deformation and cracking degree of the wood in the wooden trestle is low, the service life of the ecological wooden trestle structure is 5-10 times longer than that of a traditional wooden trestle, and the ecological wooden trestle structure has ecological, environment-friendly and economic characteristics.
