This invention generally pertains to a composite building material comprising a lightweight core with a thin fiber cement facing on one side of the core and a second facing material on the other side. The fiber cement facing that is used on at least one of the faces of the building material is 3/16″ or less, more preferably ⅛″ or less. The green fiber cement facing is preferably formed by a slurry-dewatering process to form a sheet that is in a plastic, uncured, state prior to manufacture of the composite. The composite building material is assembled in an uncured state and then cured.

A composite building article is configured with one or more subsurface interfacial zones provided to improve the durability of the article. Each subsurface interfacial zone is made of a matrix of fiber cement and radiation curable material. The radiation curable material forms an interlocking network with the fiber cement to provide a interfacial zone against ingress of environmental agents that can degrade the article. The number, configuration and distribution of the subsurface interfacial zones can vary dependent on the desired characteristics of the final product. The subsurface interfacial zones also improves the adhesion between exterior coatings and the substrate as the interfacial zones can be integrally formed with the substrate as well as exterior coating layer.

A cementitious product and method of modifying the properties of a low or medium density FRC product by providing a predetermined pore size distribution. The pore size distribution is obtained such that in critical zones of the distribution, the pore volume is substantially equivalent to or less than the pore volume in a respective critical zone of a conventional high density FRC product. The resultant material provides improved properties over conventional medium density FRC products, in particular improved freeze/thaw durability and/or improved workability.

A durable, nailable, lightweight and fire resistant fiber cement article that can be a cost-effective substitute for conventional building materials is provided. The fiber cement article can be profiled to resemble a roofing article such as a wood shake or slate. The fiber cement article incorporates a hydrophobe and a viscosity enhancing agent that are each selected to control the rate of hydration of the binder. The fiber cement article is durable, is walkable and nailable without cracking during installation and maintains walkablilty after exposure in service.

The invention relates to a nano self-cleaning fiber reinforced cement product and a production method for the same, which particularly aim to realize photocatalysis antifouling self-cleaning and air purification functions on a traditional fiber cement product by means of coating. The product is mainly applied to building roofs, building curtain walls, wall decoration, municipal traffic engineering construction and modification works, and comprises a fiber reinforced cement structural layer, a fiber reinforced cement decorative finish layer, a nano isolation layer and a photocatalysis layer, wherein the fiber reinforced cement decorative finish layer is composited on the fiber reinforced cement structural layer, the nano isolation layer is composited between the fiber reinforced cement decorative finish layer and the photocatalysis layer, and the fiber reinforced cement structural layer and the fiber reinforced cement decorative finish layer are composited to mold in a mould with a modeling. Net-shaped reinforced materials are laid in the fiber reinforced cement structural layer.

An integrated fiber cement and foam cladding system is provided that incorporates foam or similar light weight material to improve the insulation capacity of the cladding system. The system includes at least a fiber cement layer and a foam layer disposed on the backside of the fiber cement layer. The system improves the R-value of the building, a measure of the building's resistance to transferring heat or thermal energy.

An insulating panel to be used in a panelized insulation system for insulating and finishing walls, including basement walls has a foam core made of inorganic materials. The system incorporates a capillary break, an integrated water drainage system and an electrical wire chase system within an insulating wall panel. Vertical slots are provided for insertion of metal studs for use in attaching the interior finish panel, such as inorganic fiber cement board with a vinyl laminate finish, onto the insulating panels. Embedding metal studs in the panel core reduces the sound transmission though the panel and eliminates thermal bridging between warm and cold surfaces. Steps on the edges and the top/bottom surfaces of the insulating panel allow more panels to join together with shiplap joints.

A fiber cement composite material providing improved rot resistance and durability, the composite material incorporating biocide treated fibrous pulps to resist microorganism attacks. The biocide treated fibers have biocides attached to inner and outer surfaces of individualized fibers to protect the fibers from fungi, bacteria, mold and algae attacks. The biocides selected have strong affinity to cellulose and do not interfere with cement hydration reactions. This invention also discloses the formulation, the method of manufacturing and the final fiber cement products using the biocide treated fibers.

The present invention provides a laminate which has a stone-like appearance comprising a fiber cement board. The cement board layer can be embossed and/or engraved and/or painted to give the impression of colors and depths. Organic polymer composition which includes inorganic filler is included in the laminate.

This invention relates to a formulation with the addition of low density additives of volcanic ash, hollow ceramic microspheres or a combination of microspheres and volcanic ash or other low density additives into cementitious cellulose fiber reinforced building materials. This formulation is advantageously lightweight or low density compared as compared to current fiber cement products without the increased moisture expansion and freeze-thaw degradation usually associated with the addition of lightweight inorganic materials to fiber cement mixes. The low density additives also give the material improved thermal dimensional stability.

The invention discloses a method for building inner and outer wall decorating plate, which comprises two flows, each flow including steps of: a primer line processing flow: (1) thickness sanding and dedusting, (2) roller painting back seal coat and curing into a first UV seal coat layer, (3) roller painting UV penetrant twice, (4) leveling by infrared ray, (5) coating UV putty at the front and UV curing and generating a UV putty layer, (6) roller painting the UV seal coat for three times and respectively curing and generating three second UV seal coat layers, (7) fine sanding; and a roller painting finish line flow: (1) dedusting, (2) roller painting UV glue and generating a first UV glue layer, (3) coating the UV finish for five times and curing and generating five UV finish layers. The decorating plate can solve the problems that a UV curing penetrating agent is strongly, quickly and deeply penetrated into a fiber reinforced calcium silicate slab or a fiber cement slab, deeply cured to form a film and subjected to stereo chemical netlike cross-linking reaction with UV putty and UV sealing paint, and thoroughly solves the problem of adhesive force between the decorative surface layer and a substrate.
