Abstract
Abstract What is disclosed is a method of reducing the viscosities of aqueous slurries of particulate materials using anionic siliconates of silylorganocarboxylates, sulfonates and phosphonates and the compositions that are obtained thereby. An example is the use of 0.1 weight percent of ##STR1## to lower the viscosity of a 60% solids slurry of TiO 2 from 2320 cps at 25° C. to 80 cps at 25° C.

Claim 113
Dependent Claim
263 words
A composition of matter as claimed in claim 103 wherein the alkali siliconate silylorganocarboxylate is selected from a group consisting essentially of (I) a siliconate having the general formula ##STR82## and (II) a siliconate having the general formula ##STR83## wherein in both formulas, M is selected from a group consisting essentially of (i) alkali metal cations and (ii) tetraorganoammonium cations and z has a value of 2 or 3, wherein in formula (I), R is selected from a group consisting essentially of --CH 2 COOM, --CH 2 CH 2 COOM, ##STR84## wherein in formula (II), n has a value of 0 or 1; M has a value of 1 or 2, the sum of n+m is 2 and each R is independently selected from a group consisting essentially of --CH 2 COOM, --CH 2 CH 2 COOM, ##STR85## and --(CH 2 ) 2 N(CH 2 COOM) 2 when n is 0 and m is 2, and R is selected from a group consisting essentially of ##STR86## and (CH 2 ) z NH p R q ' when n is 1 and m is 1, p has a value of 0 or 1, q has a value of 1 or 2 and the sum of p+q is 2 wherein R' is selected from a group consisting of ##STR87## when p is 1 and q is 1 and R' is selected from a group consisting of --CH 2 COOM, --CH 2 CH 2 COOM, ##STR88## when p is 0 and q is 2, wherein M and z have the same meaning as set forth above.
Claim 114
Dependent Claim
57 words
A composition of matter as claimed in claim 71 wherein component (I) is selected from a group consisting of titanium dioxide, zinc oxide, iron oxide, cobalt modified iron oxide, zinc sulfide, antimony oxide, chromium oxides, basic carbonate white lead, basic sulfate white lead, barium sulfate, calcium carbonate, silica dioxide, magnesium silicate, aluminum silicate, mica and mixtures thereof.
Claim 115
Independent Claim
82 words
A method of uniformly dispersing a particulate material in an aqueous slurry which method comprises (I) contacting an aqueous particulate slurry with an organosilicon compound selected from the group consisting of (i) anionic siliconates of silylorganophosphonates; (ii) anionic siliconates of silylorganosulfonates; and (iii) anionic siliconates of silylorganocarboxylates; (II) intimately mixing the organosilicon compound and the slurry, whereby a slurry with a more uniform dispersion of particulate material than was extant before the organosilicon compound was contacted with the particulate slurry, is obtained.
