Floors/flooring polymer dispersions

All such resin solutions are based on flammable solvents and are becoming increasingly less acceptable on health and safety grounds. There is therefore increased interest in water-based polymer dispersion floor sealers, but, to date, none offer the same improvement to flooring performance that some of the resin solutions can provide. 

Polyvinyl acetate (PVA), acrylic and other polymer dispersions have been widely used as anti-dust treatments for concrete floors for many years. In general, the polymer dispersions have been similar to those used in the manufacture of emulsion paints, and until recently have tended to be based on dispersions of relatively large polymer particles (particle size 0.15-0.25 x 10 m). Dispersions are now becoming available which offer superior performance as floor sealers. The chemical and water resistance of the various polymer dispersions which have been used in the past vary considerably from the PVA types, which are rapidly softened and eventually washed out by water, to acrylic and SBR types which exhibit excellent resistance to a wide range of chemicals. Water-based sealers are gaining wider acceptance because of... 

The aqueous polymer dispersion that results from emulsion polymerization is called a latex. In applications, the polymer may be separated, or the latex may be used directly as in paints and floor coatings. 

When one hears the word latex , one usually thinks of latex gloves. The natural mbber latex used in making gloves is one of the many different kinds of latexes present in common household products, including latex paints, floor polishes, paper, carpeting, nonwoven textiles, and adhesives. Latexes are often added or applied to commercial products with the intention of enhancing specific performance characteristics, including durability, chemical resistance, and dimensional stability (373). Latexes are also known as emulsion polymers, polymer dispersions, or polymer colloids. 

For the purpose of the swelling behavior, sensitive parquet formats with bright decoration, such as beech and maple, require the development of both water- and solvent-fi-ee reactive resin flooring adhesives. In addition to epoxy, resin adhesives used in Germany are mainly polyurethane adhesives. The environment-friendly way to glue flooring is undoubtedly the use of water-based dispersion parquet adhesives. These consist of polyvinyl acetate polymer dispersions and binders such as chalk and mineral fillers. 

Thinset mortars are employed in demanding interior and exterior floor and waU applications where there may be standing water or high moisture exposure. Both one component polymer modified thinsets and two component cementitious adhesives are used. Ethylene vinyl acetate copolymers (EVA) are the predominant powder polymer base used in one component polymer modified thinsets, they are described in Chapter 13. Recently styrene acrylics or straight acrylics and styrene butadiene copolymer powders gain an increasing market share. Two component thinsets systems combine a cementitious powder mix and a separate polymer dispersion admixture. 

This chapter covers the use of synthetic polymer dispersions in the carpet industry. In 1999, carpet accounted for approximately 60 % [1] of the volume of aU floor coverings (soft and hard) sold in the USA, with an estimated [2] sales volume and value of 1.6 billion m and 11.7 biUion respectively. Of this volume, the tufted carpet and rug segment, the largest user of polymer dispersions, is dominant with an estimated 1.4 biUion m, with broadloom s share accounting for approximately 1.3 billion m. Europe and the Asia-Padfic countries produced during the same period an estimated 1.13 billion [3] and 284 milHon m soft floor covering respectively. 

Emulsion polymerization also has the advantages of good heat transfer and low viscosity, which follow from the presence of the aqueous phase. The resulting aqueous dispersion of polymer is called a latex. The polymer can be subsequently separated from the aqueous portion of the latex or the latter can be used directly in eventual appUcations. For example, in coatings applications-such as paints, paper coatings, floor pohshes-soft polymer particles coalesce into a continuous film with the evaporation of water after the latex has been applied to the substrate. 

Salts are made by reaction of acryhc acid with an appropriate base in aqueous medium. They can serve as monomers and comonomers in water-soluble or water-dispersible polymers for floor pohshes and flocculants. 

Emulsion Polymerization. Emulsion polymerization is the most important industrial method for the preparation of acryhc polymers. The principal markets for aqueous dispersion polymers made by emulsion polymerization of acryhc esters are the paint, paper, adhesives, textile, floor pohsh, and leather industries, where they are used principally as coatings or binders. Copolymers of either ethyl acrylate or butyl acrylate with methyl methacrylate are most common. 

Polymer-modified cementitious floor toppings are now widely used instead of separately laid granolithic toppings. The polymers used are normally supplied as milky white dispersions in water and are used to gauge a carefully selected sand/aggregate/cement mix as a whole or partial replacement of the gauging mortar. They must always be mixed in a forced-action mixer. 

Polymer solutions and dispersions find many practical applications. We can cast films from some polymers, and we use many others to form coatings. Coatings can be produced from either solutions or dispersions such as polymer emulsions (latexes). Examples include paint, varnish, textile finishes, adhesives, and floor waxes. Other useful latex products are latex gloves, condoms, and balloons.

Polystyrene Dispersions. On account of their glass transition temperature T of ca. lOO C, polystyrene dispersions do not form films at room temperature. These rigid polymers can only be applied with means of heat drying (e.g., to stiffen fabrics and nonwovens). Film formation is not required in agents used to protect floor coverings and paper coatings (plastic pigments) in this case polystyrene is therefore applied in the form of a dispersion at room temperature.
