Abstract
A temperature-activated polysilicic acid is prepared by heating an acidified aqueous alkali metal silicate. The temperature-activated polysilicic acid is used in the production of paper for improvement of retention and water removal.
Claims
AMENDED CLAIMS
[received by the International Bureau on 22 July 19% (22.07.96); original claims unchanged; new claims 50-63 added (2 pages)]
50. A temperature-activated polysilicic acid prepared by heating an acidified aqueous alkali metal silicate, in which the pH of said polysilicic acid is about 0 to 5.
51. A temperature-activated polysilicic acid prepared by heating an acidified aqueous alkali metal silicate, in which the acidified aqueous alkali metal silicate is heated at a temperature of about 30 to 250°C for about 1 to 120 hours.
52. The polysilicic acid of claim 51, having a pH of about 0 to 5.
53. The polysilicic acid of claim 50 or 51, having a pH of about 0 to 2.
54. The polysilicic acid of claim 50 or 51, wherein the aqueous alkali metal silicate is acidified by slow addition of a diluted alkali metal silicate solution into a mineral acid.
55. The polysilicic acid of claim 53, wherein the mineral acid is selected from the group consisting of sulfuric acid, hydrochloric acid or phosphoric acid.
56. The polysilicic acid of claim 50 or 51, wherein the aqueous alkali metal silicate is acidified by slow addition of a diluted alkali metal silicate solution into an ion exchange agent or an organic acid such as acetic acid.
57. The polysilicic acid of claim 53, wherein the aqueous alkali metal silicate is sodium silicate.
58. The polysilicic acid of claim 50, wherein the acidified aqueous alkali metal silicate is heated at a temperature of about 30 to 250°C for about 1 to 120 hours.
59. The polysilicic acid of claim 57, wherein the acidified aqueous alkali metal silicate is heated at a temperature of 60°C for 20 hours.
60. The polysilicic acid of claim 50 or 51, wherein the acidified aqueous alkali metal silicate is heated under pressure necessary to achieve a desired temperature.
61. The polysilicic acid of claim 50 or 51, wherein the heated and acidified aqueous alkali metal silicate is mixed at room temperature and diluted with water.
62. The polysilicic acid of claim 60, wherein the heated and acidified aqueous alkali metal silicate is mixed at room temperature for 72 hours and diluted to 0.15% Si02.
63. The polysilicic acid of claim 50 or 51, having a specific surface area of about 1350 to 1600 τττ/g-
