Problems solved by technology

[0003] On the other hand, it is recognized by the papermaking industry that the filling of fillers is very limited, and excessive filling will lead to serious deterioration of various technical indicators of paper, especially the mechanical strength (such as breaking length, tear strength, etc.)
In addition, it will also affect the papermaking process index and printing performance index

[0038] Preparation of Surfactant

[0039] Surfactant 1

[0040] In 13.0 gram of aluminum hydroxide, add 40 gram concentration and be the sulfuric acid solution of 60% by weight, stir at about 70 ℃ for 0.5 hour to carry out acidolysis, then add 12.5 gram of sodium silicate and 150 milliliters of water, stir at about 70 ℃ for 10 Minutes, cooled to crystallize, dried at about 100°C, and then pulverized to obtain Surfactant 1.

[0041] The chemical composition of Surfactant 1 measured by international general chemical full analysis method is: 13.1 parts by weight SiO 2 , 11.0 parts by weight Al 2 o 3 , 40.2 parts by weight SO 4 2- , 38.1 parts by weight of water of crystallization and 0.30 parts by weight of Fe 2 o 3 . where Fe 2 o 3 It is brought about by the impurities contained in the raw materials used.

[0042] Surfactant 2

[0043] Add 27 grams of concentration to 9.1 grams of aluminum hydroxide and be 60% by weight of sulfuric acid solution, stir at about 80°C f...

Embodiment 1

[0050] Mix raw materials 35 grams of bentonite (purchased from Sichuan Shuangliu Bentonite Powder Factory), 42 grams of talc (purchased from Liaoning Yingkou Nonmetal Company), 35 grams of natural calcium metasilicate (purchased from Jilin Lishu wollastonite company) with a plastic mixer , the trade name is Dadingshan brand), 7 grams of magnesium oxide (purchased from Liaoning Dashiqiao Non-Metal Company), pre-grinded into fine powder; 9.0 grams of surfactant 1 was pre-ground with a C×132 type superfine pulverizer Grinding into a fine-grained powder; using a plastic mixer to mix the above two fine-grained powders evenly, and further grinding to an average particle size of 5 microns.

[0051] The obtained composition is a white powder with a whiteness of 90%. Measured by international general chemical full analysis method, the weight percentage of fibrous particles is 35%. Measured by S-530 electron microscope of Hitachi, Japan, the aspect ratio of fibrous particles is 11. Mea...

Embodiment 2

[0053] Mix 25 grams of bentonite (purchased from Sichuan Shuangliu Bentonite Powder Factory), 32 grams of talc (purchased from Liaoning Yingkou Non-metallic Company), 25 grams of natural calcium metasilicate (purchased from Jilin Lishu wollastonite Company) with a plastic mixer , the trade name is Dadingshan brand), 5 grams of magnesium oxide (purchased from Liaoning Dashiqiao Non-Metal Company), pre-grinded into fine powder; 6 grams of surfactant 2 pre- Grinding into a fine-grained powder; using a plastic mixer to mix the above two fine-grained powders evenly, and further grinding to an average particle size of 8 microns.

[0054] The obtained composition is a white powder with a whiteness of 88%. Measured by the international general chemical full analysis method, the weight percentage of fibrous particles is 15%, and measured by the S-530 electron microscope of Hitachi, Japan, the aspect ratio of the fibrous particles is 11.

Abstract

The present invention discloses a filler composition, which mainly comprises (by weight portion) 35-45 portions of SiO2, 7.2-16 portions of CaO, 15-19 portions of MgO, 5-9 portions of Al2O3, 3-5 portions of SO4 2- and 4-31 portions of crystal water, also contains Fe2O3, Na2O and K2O, their total weight portion is less than 1.8% of weight portion of complete composition. Said composition is mainly made up by using bentonite, talcum, natural calcium metasilicate, magnesium oxide or magnesium carbonate and surfactant. The main chemical composition of said surfactant contains (by weight portion) 11-13 portions of SiO2, 8.5-11 portions of Al2O3, 36-40 portions of SO4 2- and 28-38 portions of crystal water, also can contain Fe2O3, CaO, Na2O and K2O, their total weight portion is less than 8.1% of weigh portion of complete surfactant.

Description

technical field [0001] The invention relates to a filler composition, its preparation method and application, in particular to a paper-making filler composition, its preparation method and its application in papermaking. Background technique [0002] The main raw material for papermaking is plant fibers, which are interwoven into a network structure in paper, thus endowing paper with various properties. In the papermaking industry, in order to save the amount of plant fibers and improve some properties of the paper, various fillers are usually added to the papermaking industry, such as calcium carbonate, talcum powder, and clay (Kaoline). International patent application WO 01 / 44573 discloses the preparation of paper products by adding at least one aluminum compound and at least one silicate to pulp. US5300147 discloses a low-brightness magnesium silicate SLR filler, a low-brightness paper containing the filler, a preparation method of the filler and an application in paper...
