  • Patent number: 5112657
    Abstract: In the present invention, polymer binder systems are filled with inert fillers, such as calcium carbonate, and with specific thermoplastic microspheres bearing a surface coating of an inert particulate material compatible with the polymer binder system. The preferred inert particulate material on the microspheres is particulate or fibrous forms of calcium carbonate. The microspheres have a very low density, and the inert particulate for fibrous coating is thermally bonded to surface thereof. The microspheres may be employed in proportions up to as much as about 70 volume percent of the casting or molding composition, resulting in a product of exceptionally low weight and density.The products of the present invention also provide high impact strength, high resistance to cracking and crack propagation, high tensile and yield strength, and a high modulus of elasticity, particularly compared to the usual cast marble products known to the art.

  • Patent number: 4863796
    Abstract: A family of synthetic alkali metal aluminosilicates (SAMS) are produced by the hydrothermal reaction between kaolin clay and alkali metal silicates. The integrated composition of the SAMS products is a unique entity having an overall composition ofxM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2.zH.sub.2 Owhere x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is an alkali metal, y is the number of moles of SiO.sub.2 in the unique SAMS compsoition, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The composition essentially comprises altered kaolin clay platelets with an integral rim or protuberance of essentially amorphous alkali metal silicate-kaolin reaction product. The unique SAMS compositions are structured materials in which the structure can be controlled, and are therefore useful as functional fillers, as TiO.sub.2 extenders, as silica extenders or as reinforcing agents for paper, paint, rubber, plastics and specialty products.
