Definitions
- the extrusion is a hollow strip with flat sidewalls and slotted bottom
- a special rubber cement as a primer is applied to the flat sidewalls of the strip and to the walls of the joint in the pavement or the like, whereupon the strip is inserted in the joint, the walls of the strip are allowed to spring outwardly into contact with the walls of the joint, and the solvent in the primer is then allowed to evaporate.
- the uncured strip is cemented tightly in place.
- This invention relates to a new expansion joint composition, an expansion joint strip of novel design made therefrom, a method of sealing an expansion joint with such a strip and the resulting concrete paving assembly.
- a cured neoprene extrusion of complex multi-channel cross-section as an expansion joint sealant strip.
- a cured extruded neoprene strip having narrow walls extending in crisscross fashion from one side wallto the other side wall is inserted in the joint so as to be under compression.
- the strip is compressed from 50 to 75% prior to its insertion.
- our invention involves a novel approach to the expansion joint'problem.
- the walls of an uncured strip are permanently bonded to the walls of the joint so that the joint is completely sealed against access of water, salt, etc.
- the strip is so designed that in combination with this permanent bonding feature it can expand or contract freely with the contraction and expansion of the concrete slabs without reducing or interfering with the integrity of the seal.
- the permanent strong bonding feature is made possible by making the strip from a special uncured composition which we have. invented and which is fully described below.
- FIG. 1 is a cross-section of an expansion joint strip made according to our invention, prior to its insertion in the joint
- FIG. 2 is a cross-section of the finished joint assembly. 7
- thermoplastic polymer selected from the group consisting of a block copolymer having the general configuration A-B-A wherein the As are polymeric blocks of alkenyl aromatic hydrocarbons typified by styrene, each A having an average molecular weight of 2,500 to 100,000 and B is a polymeric block of a conjugated diene, typified by butadiene, having an average molecular weight of 25,000 to 500,000 and -hydrogenated derivatives of such block copolymers and (2) reclaimed rubber.
- the block copolymer, whether hydrogenated or not, is fully described in Canadian Patent 740,027 which is hereby incorporated herein by reference.
- Any kind of reclaimed rubber may be used, examples being neoprene reclaim, SBR reclaim including high styrene SBR 7 (made with an unusually high styrene-butadiene ratio or by blending regular SBR with a high styrene-low butadiene resinous copolymer) reclaim, butyl reclaim, natural rubber reclaim, butadiene-acrylonitrile rubber reclaim, EPDM re claim, etc.
- SBR reclaim including high styrene SBR 7 (made with an unusually high styrene-butadiene ratio or by blending regular SBR with a high styrene-low butadiene resinous copolymer) reclaim, butyl reclaim, natural rubber reclaim, butadiene-acrylonitrile rubber reclaim, EPDM re claim, etc.
- SBR reclaim including high styrene SBR 7 (made
- the reclaimed rubber component of our composition is the rubber compounding material commonly and widely available under the designation reclaimed rubber” or rubber reclaim" and as is well-known made by reclaiming vulcanized natural or synthetic rubber, especially that in scrap form, by methods which are equally'well-known to the art. Examples-of Introduction to Rubber Technology, edited by Morton,
- the relative proportions of the block copolymer and reclaimed rubber can be varied widely depending upon the properties, including physical properties, desired in the joint sealing material. Preferably we use from 50 to 200 parts by weight of rubber reclaim per parts of block copolymer.
- an extrusion aid or aids typically employing from 5 to 45 parts of extrusion aid and 25 to 100 parts of plasticizer with 100 parts of the block copolymer and from 50 to 200 parts of rubber reclaim, all parts being by weight.
- the preferred extrusion aid is mineral rubber which, as is well-known in the art, is a bituminous material, typified by gilsonite or blown petroleum asphalt and described for example on pages 749 and 750 of The Chemistry and Technology of Rubber” by Davis and Blake, (published 1937 by Reinhold) and on page 157 of Modern Rubber Chemistry (published 1948 by Van Nostrand) by Barron.
- extruding aids known to the art may be used in place of or in addition to mineral rubber.
- One such extruding aid which gives excellent results when used in relatively small amounts in conjunction with mineral rubber, is a fatty acid soap.
- plasticizer component we may use any non-volatile plasticizer or plasticizers compatible with the other components of the mixture and typified by monomeric esters such as tricresyl phosphate, dioctyl phthalate, etc., plasticizing resins for example a plasticizing resin derived from urea-formaldehyde and exemplified by Plastigen G made by BASF, a plasticizing polyester or alkyd resin, often termed a polymeric ester plasticizer, exemplified by the resinous polyester materials sold under the trademark Paraplex" made by Rohm & Haas, etc., or non-volatile petroleum oils commonly used as extender oils for rubbery materials, exemplified by Circosol 4240/42 x H and Circolight oils both made by Sun Oil Co. As already indicated, we may use several plasticizers instead of only one.
- monomeric esters such as tricresyl phosphate, dioctyl phthalate, etc.
- plasticizing resins for
- composition of our invention are intimately mixed together in any suitable way wellknown in the rubber art, to achieve a good mixture.
- This mixture is then extruded inthe conventional manner used in rubber technology using an extrusion die shaped to give the supplied in reels from which it can simply and rapidly be fed into the joint, using suitable applicator equipment for applying the primer describedbelow to the walls of the joint and to the Strip.
- Typieally t'he" eIon'gat-ion'of the materialof'our strip ranges from 500 to 1000% over a temperature range of from -40?F. to +120F.; this range embraces the temperatures commonly encountered in this country. Its resiliency and hardness are such as to prevent the undesired penetration of stones, gravel, etc. into the joint, which would destroy its effectiveness, and yet the hardness is not so great at sub-zero temperatures such as 40F. as to make the strip brittle. With regard to elasticity, the material returns, after elongation to 200%, almost immediately to its original length and after elongation to 1000% returns to 150% of its original length within 1 minute and to its original length within minutes.
- the extruded strip comprises downwardly and outwardly extending side walls 2, a troughlike upper wall constituting a hinge formed by portions 3 which slope downwardly and mergeat the center 4 in such a way that when the strip I is compressed laterally for insertion it will not bulge upwardly, and integral downwardly and inwardly extending projections 5 which terminate short of the center so as to allow compression of the strip just prior to insertion in the joint.
- These projecting portions 5 are pointed as indicated at 6 to facilitate insertion.
- the outer walls 7 of projections 5 are sloped so that the projections together have a pointed configuration which facilitates such insertion.
- strip 1 as extruded is such that when the depending side members formed by side walls 2 and projections 5 are pushed towards one another to the point where the outer faces 8 of walls 2 are substantially parallel to each other, the distance between faces 8 is only very slightly wider than the width of the joint to be filled.
- the design of the extrusion l portrayed in FIG. l is such that there is a hinging action of the depending side members.
- portions 3 constitute a hinge and the characteristics of the material from which the extrusion is made are inherently such that when the depending portions are pushed inwardly towards one another and then released they resume, so far as they can, the original position they had in the extrusion as it was formed.
- a primer which is a neoprene cement (i.e. an organic solvent solution of neoprene containing a curative or curatives) capable of forming in cooperation with the material of the extrusion an adhesive bond which permanently and strongly bonds the walls 2 of the strip 1 to the concrete and forming a fluidtight seal therebetween.
- This primer also penetrates the permeable walls of the concrete slabs thereby strengthening the concrete and, more importantly, preventing accidental in- Toluol H:
- a typical primer formulation suitable for use in our invention is a so-called rubber cement made from neoprene compounded with suitable curatives, such as magnesium oxide or zinc oxide or both, an antioxidant if desired and a phenolic resin or resins ofthe type commonly used in making neoprene 3O cements, all dissolved and suspended in a suitable volatile organic solvent or solvents also of known type to give an appropriate total solids content.
- suitable curatives such as magnesium oxide or zinc oxide or both
- an antioxidant if desired
- a phenolic resin or resins ofthe type commonly used in making neoprene 3O cements all dissolved and suspended in a suitable volatile organic solvent or solvents also of known type to give an appropriate total solids content.
- Neoprene AF (so-called self-curing neoprene) 100 Magnesium oxide (curative for neoprene) 4 Zine oxide (curative for neoprene) 5 Antioxidant a 1 Heat-reactive oil-soluble tertiary butyl pheital-formaldehyde resin (such as TR-14634 made by Union Carbide) 45 Thermoplastic Terpene-modilicd phenol formaldehyde resin, typically having a capillary melting point of about 335 F.
- extrusion strip material is resilient so that after being laterally compressed for insertion into the joint and then released the depending side portions of the strip immediately spring outwardly and contact the joint walls with sufficient force to hold the strip in place until the strong adhesive bond is established.
- Our composition can also be used for sealing the joints between doors, windows and other elements of a buiding and the structure of the building proper.
- it can be used, preferably in the form of a triangular extrusion, for corner joints such as are encountered around the frames of doors and windows, the primer being applied over the area which must be sealed in order to hold the extrusion in position.
- It can also be used for sealing glass in a window frame; in this application it may be extruded in the form of a channel which is slipped over the edges of the glass prior to positioning in the frame, the glass being subsequently locked in place in any obvious way.
- composition can also be used as a weather stripping material; in this usage the composition is typically applied as an extrusion of varying design such that one side is adhered to a rigid member and another portion of the extrusion is hingelike and is compressed by the closing of the door or window in order to provide the necessary seal.
- our composition is also well adapted to be used in sheet form, typically calendered, for flashing and roofing.
- a suitable organic solvent such as for example toluol or xylol, which can be used either by itself or in the form of a rubber cement, to the roofing substructure in order to effect permanent bonding of the flashing or roofing.
- roofing applications we typically place large sheets of our composition in position with slight overlapping at the edges and we effect fusion of the material in the overlapping area to form an integral joint by the application of an organic solvent or rubber cement of the type just referred to; such fusion of the material in the overlapping areas is possible because our composition is uncured.
- Our composition can also be used in sheet form for holding water in irrigation ditches or basins or in the reservoirs behind dams.
- large sheets of the material are disposed in slightly overlapping fashion over the earth area and the overlapping portions of the sheets are fused in the manner just described.
- Any suitable fibrous material may be employed for this purpose, examples being sisal, cotton fiber, nylon fiber, ground uncured rubberized textile fabric cuttings which are formed as waste in the manufacture of pneumatic tires, etc.
- composition of our invention has a great many useful applications. It will be understood of course that the foregoing is by no means a complete enumeration of the uses to which our composition may be put.
