Definitions
- the invention relates to coated particles of an alkaline earth metal carbonate, preferably CaCO 3 , which are at least partially coated with at least one coating agent and have a specific surface of more than 50 m 2 g "! before coating.
- the invention also relates to the production of such particles and their use.
- Calcium carbonate is used as a filler material in paintings, rubber, paper, pharmacy, plastics and so on. Such calcium carbonate is obtained from natural deposits, thereafter being finely ground, or is obtained via chemical precipitation and drying of the precipitate.
- yet another category of process features the treatment of a calcareous filler to improve its wettability by means of hydrocarbons and plastic materials by contacting the same with alkylarylsulfonic acids or salts, the calcium salt thereof being essentially insoluble in water, in an amount at least equal to that required to form a monomolecular layer or a coating covering the entire surface of the particles or grains, as described in FR-A 2 138 300.
- This publication specifically relates to calcium carbonate powders having a low specific surface, on the order of 0.5 to 3 m 2 /g (BET method).
- FR-A 2 480 771 discloses the treatment of calcium carbonate powder with an organic sulfonic acid or salt thereof, together with a fatty acid compound. The beginning calcium carbonate has a specific surface, measured by the BET method, between 50 mVg and 0.2 mVg.
- Plastisols are dispersions of polymers, often comprising polyvinyl chloride (PVC) in organic solvents having high boiling points and usually containing softeners and stabilizers. Plastisols are useful e.g. for coating metals and other substrates, such as underbody sealants for automobiles, for preparing artificial leather, etc.
- PVC polyvinyl chloride
- Polyvinyl chloride plastisols offer several advantages for use as sealant compositions : a good balance of strength, elongation and toughness, minimal to no volatile organic component and low cost.
- a plastisol When a plastisol is intended for application by means of a spray gun, it should adhere to the substrate and form a smooth film thereon. Flowing and any movement of the film due to gravitational forces should be suppressed as long as the plastisol is liquid or pasty, i.e. before it is cured. This kind of adhesion can be achieved by modifying the rheological properties of the plastisol.
- a good plastisol When being applied to a substrate by means of a spray gun, a good plastisol should exhibit a high viscosity when the shearing force is low and a low viscosity when the shearing force is high. Furthermore, it should be characterized by a high yield stress and good thixotropic properties.
- the filler material should be suitable for plastisols which may be applied by a spray gun, i.e. a plastisol containing said filler material should have a high yield stress, it should exhibit a high viscosity when the shearing force is low and a low viscosity when the shearing force is high. Furthermore, these properties should be constant for a certain period of time.
