281 results about "Decorative laminate" patented technology

Decorative laminates are laminated products primarily used as furniture surface materials or wall paneling. It can be manufactured as either high- or low-pressure laminate, with the two processes not much different from each other except for the pressure applied in the pressing process.

Process for the manufacturing of an improved core for decorative laminates and a decorative laminate obtained by the process

A process for the manufacturing of a core forming a carrying structure for decorative laminates. The core comprises particles of cured, and optionally foamed, rigid, polyurethane, polyisocyanurate and / or phenolic resin. The particles are bonded to each other in a pressing procedure with a bonding agent comprising an adhesive such as a polymerizing monomer.i) The particles are achieved by grinding cured, and optionally foamed, rigid, polyurethane, polyisocyanurate and / or phenolic resin so that it passes through a 2 mm screen, preferably a 1 mm screen,ii) 100 parts per weight of particles is mixed with 1-100 parts per weight of fiber, the fiber additive having an average length in the range 1-15 mm.iii) The particle-fiber mixture is allowed to absorb a selected amount of water, the amount of water being in the range 1-15% by weight, The water is either added at any stage before the adding of bonding agent, and / or being used as a solvent in the bonding agent, and that,iv) 85 parts per weight of the particle mixture is mixed with 2-15 parts per weight of a bonding agent, the bonding agent selected from the group consisting of,a) A mixture of polyols, such as polyester or polyether, crude methylene diphenyl diisocyanate and possibly a small amount of blowing agent in a ratio forming a polymeric resin with a density in the range 600-1400 kg / m3.b) A formaldehyde based resin such as phenol-formaldehyde resin, urea-formaldehyde resin, melamine-urea-formaldehyde resin, melamine-urea-phenol-formaldehyde resin or phenol-resorcinol-formaldehyde resin, orc) Polyvinyl acetate resin.v)The mixture is applied between the belts of the continuos belt press or the press plates of a static press, optionally with at least one intermediate carrier web, the belts or press plates allowing a mainly uniform and specified material thickness to form. A slightly porous and preconditioned core with a selected water content in the range 0.8-12% is hereby achieved. The invention also relates to a decorative laminate achieved through the process.

Building external wall furring brick decorative plate

The invention discloses a building external wall furring brick decorative plate. Currently, external wall decorative plate researches are focused on functional respective of thermal insulation, crack resistance, flame prevention, and the like. However, the decorative function, except change in color, is not shown. According to the invention, glass fiber mesh cloth or synthetic fiber non-woven fabric cloth is adopted as an enhancing mesh cloth; cement mortar, re-dispersible powder or alkali-resistant elastic latex, synthetic staple fiber, and cellulose ether are prepared into a composite slurry; the slurry is pressed into a base blank; and furring tiles are adhered to the base blank, such that the furring brick decorative plate is prepared. According to the invention, the adhesion work for adhering small tiles on the external wall is changed into the adhesion work of large plates, such that operation is simplified. The decorative plate has the advantages of a decorative plate. Also, tiles of different patterns, colors, and sizes can be adhered, such that appearance and practicality are both taken into consideration. The base blank is prepared by using the composite slurry and the enhancing mesh cloth, such that the decorative plate has excellent crack resistance, tensile resistance, and light weight in the physical respect.

Preparation method of high-light-resistant titanium dioxide pigment for laminated paper

The invention provides a preparation method of a high-light-resistant titanium dioxide pigment for laminated paper. The method comprises the following steps: preparing titanium dioxide slurry from a rutile-type titanium dioxide initial product prepared by adopting a chlorination process method, and adjusting the pH value to 8.5-10.5; adding a citric acid radical-containing organic substance as a dispersing agent, and performing grinding treatment; performing heating to 55-65 DEG C for coating treatment, performing coating by using a dense aluminum phosphate coating layer, performing coating byusing a loose silicon aluminum compound coating layer, and performing coating by using a loose boehmite-type hydrated aluminum oxide coating layer; performing washing by using deionized water until conductivity of a filter cake is greater than 15000 omega*cm, and performing drying; and adding amino-containing organic matter in the steaming powder process, and performing organic coating treatmentto obtain the titanium dioxide pigment for the decorative laminated paper. The method provided by the invention has the advantages that the titanium dioxide pigment prepared by the method has the characteristics of high light performance, good whiteness and a high retention rate in the laminated decorative paper, and the prepared titanium dioxide pigment has a medium color bottom phase and the advantage of easy color matching, and can be widely used in the field of the high-end laminated decorative paper.
