LATEX SYSTEMS FOR DUST CONTROL IN SUPPORT OF MILITARY OPERATIONS

THE RESULTS OF A PHASE OF A PROGRAM TO DEVELOP LATEX- BASED COMPOUNDS FOR USE AS DUST-CONTROL AGENTS IN MILITARY OPERATIONS ARE PRESENTED. BOTH SYNTHETIC POLYMER EMULSIONS AND NATURAL RUBBER LATEX HAVE BEEN INVESTIGATED FOR THEIR SUITABILITY IN PREPARING DUST-SUPPRESSANT SOIL COATINGS BY SPRAY APPLICATION TO THE SOIL. SPECIAL EMPHASIS IS PLACED ON THE DEVELOPMENT OF FORMULATIONS BASED ON NATURAL RUBBER LATEX BECAUSE OF THE POTENTIAL AVAILABILITY OF THIS MATERIAL IN THE SOUTHEAST ASIA THEATER OF OPERATIONS. THE SYNTHETIC POLYMER EMULSION SYSTEMS EVALUATED INCLUDED VINYL EMULSIONS, ACRYLIC EMULSIONS, NITRILE AND POLYCHLOROPRENE RUBBERS, AND A POLYURETHANE RESIN EMULSION. AMONG THESE MATERIALS A COMPOUNDED NEOPRENE 650 OF GOOD STRENGTH AND EXTENSIBILITY FURNISHED A FORMULATION NOTABLY RESISTANT TO DEGRADATION ON OUTDOOR EXPOSURE. A BROAD RANGE OF CURING AGENTS AND ANTIOXIDANTS FOR COMPOUNDING NATURAL RUBBER LATEX WERE INVESTIGATED. THESE ADDITIVES WERE EVALUATED BY DETERMINING THEIR EFFECT ON THE STRENGTH AND ELONGATION OF SOIL COATINGS, THE RESISTANCE OF THE COATINGS TO OUTDOOR AGING, AND THE VISCOSITY OF THE LATEX COMPOUND AFTER STORAGE. OUTDOOR AGING TESTS IN MASSACHUSETTS WERE SUPPLEMENTED BY ACCELERATED AGING TESTS INVOLVING EXPOSURE TO ELEVATED TEMPERATURE AND ULTRAVIOLET RADIATION. THE EFFECTS OF SOIL-COATING THICKNESS, APPLICATION TO INCLINED SURFACES, AND PRIOR TREATMENT OF SOIL WITH PENETRATING MATERIAL WERE INVESTIGATED. AN ANALYSIS WAS MADE OF THEIR STRESSES IMPOSED ON SOIL COATINGS BY AIRCRAFT PROPELLER BLAST. A SOIL-COATING FORMULATION BASED ON NATURAL RUBBER LATEX AND DEVELOPED EARLY IN THE PROGRAM WAS SUBJECTED TO FIELD TRIALS AT YUMA PROVING GROUP. THIS COATING IN UNMODIFIED FORM AND REINFORCED WITH GLASS FIBERS WITHSTOOD PROPELLER BLAST TESTS BUT DEVELOPED A TACKY SURFACE ON CONTINUED EXPOSURE. AS A RESULT OF SUBSEQUENT FORMULATION EVALUATIONS, A DEGRADATION-RESISTANT COMPOUND DESIGNATED NO. 267 AND SUITED FOR STORAGE AND SHIPMENT IN THE COMPOUNDED STATE WAS DEVELOPED. /AUTHOR/
