Definitions

  • the present invention relates to drywall joining systems for seams or repairs generally, and more particularly to tape used for drywall installation and repairs.
  • Walls made from gypsum wall board or drywall are conventionally constructed by affixing the boards to studs or joints and filling and coating the joints with a specially prepared adhesive called "joint compound.” This process is also used to make repairs of defects, such as holes and dents, including those around electrical boxes, piping and duct work, as well as corners created by the intersection of drywall boards.
  • Drywall tape adds strength and crack resistance as well as smooth concealment at flat joints and inside corners.
  • two types of drywall tape have been employed - a simple kraft paper strip which is adhered to the drywall surfaces by a bedding coat of joint compound or "mud," and glass fiber tape, which can be applied with joint compound or self-adhered.
  • Kraft paper tape must be carefully positioned and care must be taken not to discharge the mud onto non-working surfaces.
  • Glass fiber tape on the other hand, provides exceptional wet and dry strength and resists stretching and wrinkles. It can be laid flat and resists tearing under load.
  • a joint treatment system which includes reinforcing tape and joint compound, must provide joints as strong as the gypsum board itself. Otherwise, normal structural movement in the wall or ceiling assembly can result in the development of cracks over the finished joint.
  • fiberglass leno-weave mesh tape when used with conventional joint compounds are more prone to cracking than joints finished with paper tape and conventional joint compounds. Because of this, some manufacturers, such as United States Gypsum Company, Chicago, Illinois, have manufactured glass fiber tapes with cross-fiber construction to provide greater drywall joint strength than conventional fiberglass leno-weave mesh tapes. Such tapes include Sheetrock® brand fiberglass drywall tape and Imperial® brand tape.
  • the Imperial® brand tape includes an open weave of glass fibers (100 meshes per square inch) which is coated with a binder and slit to roll width. Spirally woven (leno) long strands and the binder coating reduce edge raveling and fraying and keep the loose threads from defacing finishing surfaces.
  • Fibatape® glass tape available through San Gobain Technical Fabrics, Ontario, Canada. This product is an SBR rubber-coated glass fiber tape with a self- adhesive backing. The tape is self-adhered to a drywall seam, and then covered with layers of drywall compound. Samples of a drywall joint made with Fibatape® tape have been tensile tested in accordance with ASTM C 474 (Appendix) which measures the strength to first crack of a tape-compound sample coated in electrically conductive paint. The strength is measured until the first crack in the paint occurs, which breaks the electrical continuity along the surface and registers the ultimate tensile load.
  • ASTM C 474 Appendix
  • a drywall tape suitable for joint compound repairs and joint covering includes a web of glass fibers and a coating disposed over a portion of the glass fibers.
  • the coating comprises a resinous binder which is at least partially soluble or dispersible in the joint compound.
  • the coating is further capable of forming an adhesive bond with the joint compound when set.
  • the re-wettable coating can be chemically very similar to the binding resin that makes up the compound itself, or is at least soluble or dispersible in the joint compound. Most preferably, the re-wettable coating is soluble or dispersible in the water content of the joint compound so that it flows together with the compound on a microscopic scale. Once dry, the coating most preferably becomes a very rigid film that is well able to transfer loads from the joint compound to the fiber. This permits the joint compound and drywall tape of this invention to act much like a fully integrated composite, which increases the mechanical properties of the joint.
  • the re-wettable coating comprises a soluble or dispersible resinous binder alone, or in combination with a blocking agent, such as a wax.
  • a soluble binder such as polyvinyl acetate (PVAc)
  • PVAc polyvinyl acetate
  • the preferred re-wettable coating contains PVAc resin which is very hydroscopic. Water vapor absorption can cause a roll of tape made with PVAc resin to block or fuse together, which causes the roll to bind. The roll of tape can also flow plastically and deform the shape of the tape roll.
  • Blocking agents such as paraffin wax, make the PV Ac-based coating vapor resistant. Only when contacted with liquid water, such as when the tape is applied to a wall and coated with joint compound, does the PVAc resin re- wet and become soluble.
  • a method for preparing a drywall joint includes disposing a pair of drywall boards in adjoining relationship to one another to form a seam region.
  • the drywall tape of this invention is disposed over the seam.
  • This drywall tape includes a web of glass fibers having disposed thereon a resinous binder capable of re- wetting and setting when contacted with the joint compound.
  • a first joint compound layer is applied over the drywall tape so as to re-wet the resinous binder.
  • the first joint compound layer and re-wetted resinous binder on the tape are then dried to form an adhesive bond.
  • FIG. 1 is a partial, front perspective view of the preferred drywall tape of this invention
  • FIG. 2 is a partial, enlarged side-plan view, illustrating a coating on the drywall tape of FIG. 1
  • FIG. 3 is a partial, top, cross-sectional view of a finished flat drywall joint of this invention
  • FIG. 4 is a graphical depiction of the average load to first crack for various drywall tape constructions, including those of the present invention.
  • This invention provides drywall tape, drywall joints, methods of preparing drywall joints, and reinforcements for cementitious materials generally. It is understood that while the present invention is preferably related to drywall seam or repair constructions, the re-wettable coatings on the glass and other reinforcing fibrous webs provide practical solutions to reinforcing gypsum fiber board, gypsum wall board, glass-faced gypsum board, tilebacker boards, high impact gypsum wall board, and concrete board constructions.
  • the re-wettable coatings of this invention can be useful with cementitious materials such as gypsum, portland cement, and combinations of these materials with fillers or aggregate, such as mortar, cement and concrete.
  • This invention can be used to enhance the performance of existing self-adhesive drywall joint tapes and patches, or tapes and patches which do not have a pressure-sensitive adhesive on one side of their construction.
  • the benefits of a re-wettable resinous binder are realized whether a pressure-sensitive adhesive is present on the web or not.
  • drywall includes wall board, fiberboard, glass-faced gypsum boards, and their equivalents.
  • tape means a strip of material that can be provided in roll form, which may, or may not, contain an adhesive backing layer.
  • FIGS. 1-2 there is shown a preferred drywall tape 100 including a web of glass fibers 10 and an optional pressure-sensitive adhesive layer 12.
  • the re-wettable coating 14 can be viewed.
  • the re-wettable coating 14 is disposed along one or both sides of the web of glass fibers 10.
  • the re-wettable coating 14 can be disposed over 100% of the exterior surfaces of the web of glass fibers 10, over 70% of the surface area, or over less than 50% of the surface area.
  • the glass fibers of the web of glass fibers 10 are bonded together using a web adhesive binder 15, such as vinyl acetate acrylic, styrene/acrylate, vinyl/acetate, acrylic, styrene acrylic, or copolymers and mixtures thereof, etc.
  • a web adhesive binder 15 such as vinyl acetate acrylic, styrene/acrylate, vinyl/acetate, acrylic, styrene acrylic, or copolymers and mixtures thereof, etc.
  • a web adhesive binder 15 it may or may not be re-wettable, soluble or dispersible in liquid water.
  • the re-wettable coating 14 is used to also bind the fibers of the web of glass fibers together.
  • a flat drywall joint can be constructed by butt joining a pair of drywall boards 18 and 17 to form a seam region 45.
  • the drywall tape 100 can be applied with the aid of the pressure-sensitive adhesive layer 12, or when a pressure-sensitive adhesive is not employed, the drywall tape 100 can be pressed lightly into a wet joint compound layer which is thinly applied to the seam region 45 prior to application of the drywall tape 100. If joint compound is used to adhere the drywall tape 100 to the seam region 45, care must be taken to provide sufficient joint compound under the tape to prevent blistering of the tape. While embedding the tape 100, excess joint compound should be removed from the edge.
  • a first coat of joint compound 30 should applied over the tape so as to embed the tape 100 nearly completely. While embedding the tape 100, excess joint compound is removed from the edge. Added water can be included in the joint compound so as to thin it for easier application. Similar approaches can be provided for inside corners, outside corners, horizontal flat joints and hole and crack repairs, finished seams along electrical boxes and switches and seams around piping and duct work.
  • a second coat 40 of drywall compound is applied over the first coat 30, ideally with an 8 inch knife, feathering slightly beyond the first coat. If further coats are desired, the second coat 40 is allowed to dry, and a third or finishing coat (not shown) can be applied with a 10 inch knife to the flat joints. The second coat 40 or third coat can be lightly sanded if necessary.
  • the joint compound useful in the drywall joints of this invention is typically classified as either a "drying" or "setting” type.
  • the filler comprises substantially calcium carbonate.
  • the filler and the binder, along with several other known ingredients, are mixed with water. After application, when the water drys to evaporation, a dry, relatively hard cementitious material is left behind.
  • Joint compositions known as the "setting" type include at least a substantial portion of calcium sulfate hemihydrate.
  • calcination a process that removes 1 54 molecules of water from the calcium sulfate dihydrate gypsum.
  • the hemihydrate form of calcium sulfate is substantially more soluble in water than the dihydrate form of calcium sulfate.
  • the calcium sulfate hemihydrate is rehydrated to the dihydrate state. This rehydration process normally takes place over a fairly short period of time. Accordingly, it is extremely difficult to produce a setting-type joint compound for storage in a bucket, and as such, such compounds are typically provided in powder form.
  • Setting-type joint compounds also form a crystalline network upon setting, and provide a stronger, more durable bond.
  • the webs useful in manufacturing the drywall tape 100 of this invention can be provided as non-woven, woven or knitted fabrics, veils, mats, scrims, or fleece. They desirably include high strength fibers, such as glass fiber, and less desirably may include thermoplastic or thermosetting fibers, carbon, boron, graphite fibers or combinations thereof.
  • a web of glass fibers 10 having abasis weight of about 5-500 grams/m 2 , preferably about 20-120 grams/m 2 is employed.
  • This web 10 can be fabricated by weaving, such as a plane or leno weave, by knitting, by a laid scrim process or by a non-woven process, such as resin bonding randomly oriented glass fibers.
  • the webs of this invention are, desirably, at least partially porous to wet joint compound so as to form a good bond in the seam region 45.
  • a veil or fabric could be somewhat non-porous to joint compound and still be useful as a replacement for paper tape and, thus, be applied with a bedding coat of joint compound.
  • the preferred re-wettable coating 14 applied to the web desirably has the properties of being soluble or dispersible in liquid water.
  • Glass tapes of the past were often coated with polymers, such as SBR rubber or a resinous binder, such as vinyl acetate acrylic, styrene/acrylate, vinyl/acetate, acrylic, styrene acrylic, etc., which wee specifically designed to aid in handling and slitting the reinforcements without regard to how the coatings interacted with joint compounds.
  • the adhesion of traditional rubber based coatings such as SBR to setting or non-setting joint compounds is minimal, and thus, an optimum composite strength cannot be achieved, e.g., the glass fibers tend to pull out from compound when loaded.
  • the preferred re-wettable coatings 14 of this invention set to form a strong bond between the preferred glass fibers and the set joint compound so that the fibers act more as an unit to resist loads.
  • the preferred re-wettable coating 14 of this invention should be as inexpensive as the styrene butadiene rubber (SBR) or joining resin binders currently employed on glass drywall tape. This coating 14 should be easy and versatile to formulate and should run on pad rolls with water clean up being highly desirable. It should not be significantly prone to oxidation or UV light degradation.
  • the preferred re-wettable coating 14 is provided in a latex form such as an aqueous emulsion of a binder resin, blocking agent and water.
  • the preferred re-wettable coating 14 of this invention contains one or more of the resins selected from the group including: polyvinyl acetate, ethylene vinyl acetate, polystyrene, polyvinyl chloride, polyacrylate, ethylene acetate co- polymer, vinyl-acrylic co-polymer, styrene butadiene, acrylic polymer and starch; protein glues, such as casein, soy protein, animal glue and gelatin; vegetable- based glues, such as cellulosics and their chemically modified derivatives; gums (polysaccharides and carbohydrates) such as guar gum; resins (pine tar) which may not be water soluble; mucilages (agar, carrageenan and algin); inorganics such as soluble silicates (water glass) and cementitious materials (cement, gypsum), and co-polymers and combinations of these.
  • the resins selected from the group including: polyvinyl acetate, ethylene
  • the resinous binder contains polyvinyl acetate (PVAc), such as Vinac 524 polyvinyl acetate homopolymer stabilized with polyvinyl alcohol, Airflex 401 polyvinyl acetate/ethylene co-polymer stabilized with polyvinyl alcohol, both supplied by Air Products and Chemicals, Inc., of 7201 Hamilton Blvd., AUentown, PA 18195.
  • PVAc polyvinyl acetate
  • the re-wettable coating 14 preferably is provided in an aqueous emulsion or solution containing about 25-75 wt. % solids.
  • water soluble polymers in powder form may be applied with adhesive or electrostatically. Two formulations of the re-wettable coating developed within the context of this invention are found below:
  • Airflex 401 Emulsion (PVAc/ethylene co-polymer stabilized with polyvinyl alcohol 26.30% Water 9.02%
  • Hydrocer DP69 paraffin wax, anti-blocking agent 3.00%
  • Benzoflex 9-88 (dipropylene glycol dibenzoate plasticizer for PVAc) '• 7.23% '
  • Hydrocer DP69 paraffin wax, anti-blocking agent 3.00%
  • an important ingredient for preventing the PVAc resin from picking up too much water during storage is an anti-blocking agent, such as animal oils, fats, starch, dextrine, silicone oil, waxes and combinations thereof.
  • the preferred anti-blocking agent is low melting point paraffin wax.
  • the paraffin wax can be emulsified in the formulations and "blooms" to the surface when the formation is dried.
  • the blocking agent acts as a- vapor barrier to the re-wettable 14 coating on the drywall tape 100 of this invention, so as to substantially reduce blocking in tape rolls.
  • the anti-blocking agent should be less than about 5-10% by weight of the formulation so that it can be dispersed readily when the re- wettable coating 14 is made soluble by the water in the joint compound. Accordingly, the re-wettable coating 14 with the above formulations containing an anti-blocking agent and PVAc resin in solution, is capable of being vapor resistant when dry, but is water soluble or dispersible when contacted with liquid water in the joint compound.
  • the adhesive elements of this invention can be made of any known pressure-sensitive adhesive material.
  • pressure- sensitive refers to any releasable adhesive or releasable tenacious means.
  • Adhesive compositions suitable for tape include, for example, the water-based pressure-sensitive adhesive such as acrylate adhesives, e.g., isooctyl acrylate and acrylic acid copolymer, or vinyl acetate-2 ethyl hexyl acrylate copolymer which can be combined with tackifiers.
  • the adhesive may comprise the rapid setting thermoplastic "hot melt" adhesives.

  • the rollers could be adjusted for gap width or pressure to perform this function, but the solids level and the viscosity of the latex are important factors in determining the coating weight.
  • the saturated fabric is then dried either by contact with steam cans or by convection in a hot oven.
  • the web of glass fibers 10, now coated with a re-wettable coating 14, is provided with a pressure sensitive adhesive layer 12 applied to one side, usually about 3-15 grams/m of adhesive is applied.

  • the pressure-sensitive adhesive layer 12 serves to affix the drywall tape 100 to the drywall surface in preparation for drywall filling with drywall compound.
  • the web of glass fibers 10 can be saturated and dried with the re-wettable coating 14, then within the same coating line, passed over a kiss coater that applies the desired amount of latex pressure-sensitive adhesive to the fabric. The fabric then passes into a mechanical convection oven for drying of the pressure-sensitive adhesive. In either case, the web 10 is then wound into large diameter rolls for transport to a slitting department where the roll can be processed into tapes of any desired length and width.

  • Formulations 1 and 2 load reading when available. It was observed in these tests that there was at least about a 16% increase in average load to first crack using the rewettable coating of Formulations 1 and 2 over SBR coatings. Note that all samples were coated on one side with a pressure sensitive adhesive. It would be expected that the average load to first crack would be increased by a factor of two when no adhesive is applied to the back of equivalent samples. The explanation for this is that, in the case of the adhesive coated samples, half of the surface area of the glass web would be covered with a layer of low modulus pressure-sensitive material that does little to resist the loads placed on the sample.
