4126 results about "Solid wood" patented technology

Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material. Engineered wood includes plywood, oriented strand board (OSB) and fiberboard. The fact that a product is made from solid wood is often touted in advertisements. However, using solid wood has advantages and disadvantages.

Non-formaldehyde solid wood composite floor using low-density cottonwood veneers as base materials and manufacturing method thereof

The invention provides a manufacturing method of a non-formaldehyde solid wood composite floor using low-density cottonwood veneers as base materials. The non-formaldehyde solid wood composite floor is at least a cottonwood base plate assembly manufactured by combining following two raw materials: first, cottonwood veneers formed by stewing cottonwood logs at a low temperature of 10 to 50 DEC C, then rotary-cutting or slicing the cottonwood logs and afterwards drying the cottonwood logs, and second, plastic adhesive films manufactured by adopting thermoplastic resin; the treated cottonwood veneers are coated with coupling agents and are then assembled with the plastic adhesive films, and after hot-pressing and setting treatment, a cottonwood base plate is manufactured; afterwards, decorative thin wood is adopted as a surface layer and is combined with the cottonwood base plate assembly, and after cold-pressing, a floor blank is manufactured; and finally, the floor blank is milled, tenoned, slotted, and subjected to paint curing, and then a product is manufactured. Through using high polymer materials, from which no harmful substance escapes, in both the machining process and the use process, the environmentally friendly solid wood composite floor is produced.

Phase-change energy storage heat-insulation solid wood and manufacturing method thereof

The invention provides phase-change energy storage heat-insulation solid wood. The wood comprises a solid wood component, wherein magnetic Fe3O4 nanoparticles are formed in a conduit and a cell cavity of the solid wood component through in-situ attached growth, and the conduit and the cell cavity are filled with composite phase-change energy storage materials of polyethylene glycol 600 and polyethylene glycol 800; and a protective coating is painted on the surface of the heat-insulation solid wood. The heat-insulation solid wood is capable of absorbing heat to withstand excessive rise of an indoor temperature during the day, releasing phase-change latent heat for thermal retention and cold dispelling during the night, and maintaining a human body within a comfort temperature range. The invention further provides a manufacturing method of the heat-insulation solid wood. The method comprises the steps of firstly processing the solid wood component according to the required dimension; carrying out degreasing and drying pretreatment on the solid wood component, forming the magnetic Fe3O4 nanoparticles in the solid wood component through in-situ attached growth and then impregnating and filling the composite phase-change energy storage material of the polyethylene glycol 600 and the polyethylene glycol 800; and finally carrying out sanding shaping and painting the protecting coating. According to the manufacturing method, the process is simple and the cost is low.

Wood multi-layer floor composed of cut-plate and veneer and method for making same

The invention relates to a real-wood composite floor panel, which adopts a sheet-cut board with a sheet-cutting method as a core layer, a shave-cut single plate with a shave-cutting method as a surface layer, a rotary cut single plate with a rotary cutting method as a base layer, as well as all the other intermediate layers. The invention belongs to a real-wood composite floor panel, which is an artificial board in the industry of wood materials. The invention is characterized in that the core layer of the real-wood composite floor panel is a sheet-cut board that is produced with a sheet-cutting method; the surface layer of the real-wood composite floor panel is a shave-cut single-plate that is processed with a shave-cutting method; the base layer and all the other intermediate layers of the real-wood composite floor panel are rotary-cut single-plates produced with a rotary cutting method. The fabrication method is that the core layer of the real-wood composite floor panel is produced in a one-through mode covering adhesive coating, blank combination and glueing. The invention has advantages of perfect product quality, small deformation, needing no too much investment, saving wood materials, comprehensive utilization of wood materials and low cost. Except for pruducing real-wood composite floor panels, the invention can also be used to make such base material products as fine woodwork boards, real-wood doors and sheet-type furniture.

Adhesive for solid wood floor and preparation method thereof

The invention discloses an adhesive for a solid wood floor and a preparation method of the adhesive. The adhesive is a one-component moisturecuring polyurethane elastic adhesive which consists of polyether polyol, polyisocyanates, a plasticizer, padding, a catalyst, a water removing agent, a coupler and an antioxygen. The adhesive used to pave the solid floor overcomes the deficiencies that at present, in solid wood floor pavement, the solid wood floor is large in noise, free from elasticity, poor in stability, has sound like an empty drum, and cannot be used in a ground heating system and the like due to rough grounds which have to be used. The adhesive has the advantages of one-component moisturecuring, convenience in operation, strong adhesive strength, safety, environment friendliness and the like, and can be adjusted in different colors according to colors of the solid wood floors. The solid wood floors paved have the advantages of elasticity, comfort, low noise, and can be used in the ground heating system and the like, and the risk of deformation and crack of the solid wood floor can be reduced. The adhesive is suitable for paving various solid wood floors and elastically adhering skirting lines, thresholds and stairs and the like, and meanwhile the adhesive is further used for paving ceramic tiles.

Three-layer composite solid wood flooring made from same type of trees and production process thereof

The invention belongs to the technical field of building decorative materials, relates to three-layer composite solid wood flooring, in particular to three-layer composite solid wood flooring made from the same type of trees and a production process thereof. The three-layer composite solid wood flooring consists of surface boards, core boards and back boards, wherein the surface boards, the core boards and the back boards are all made from the same type of timber pressed into a whole according to crisscross grains; the thickness of the surface boards is 3-4mm, the thickness of the core boards is 8-9mm, and the thickness of the back boards is 2-3mm. The invention further discloses a production process of the three-layer composite solid wood flooring made from the same type of trees. As the three-layer composite solid wood flooring is made from the same type of trees integrally, physical properties of the three layers are the same, the three layers can be bound effectively during production, and different physical properties can keep consistent highly. Since the solid wood flooring is composited by three layers, the defect that single-unit solid wood flooring is easy to deform is overcome, and the solid wood flooring is more stable and adaptable to geothermal environments. By the production process of the three-layer composite solid wood flooring, valuable timber can be utilized reasonably and the percentage of outturn can be increased while waste of timber can be reduced.
