Description
Technical field
The present invention relates to weighting agent that is used for substrate surface and its production and use, described weighting agent is used for forming based on silicon-dioxide (SiO at substrate surface
2) coating.The invention belongs to architectural decoration material field, such as the surface of the series products that is used for cement based baking-free ceramic brick, terrazzo or ceramic brick (its average water-intake rate is greater than 10%), Shi matter brick (its average water-intake rate is greater than 0.5% but smaller or equal to 10%).
Background technology
Knownly disclose 3 parts of Chinese invention patent applications and relate at material surface and prepare siliceous ground surface filth-resisting thin film.The 1st part is " Fuctional coating making process " (application number: CN200410096661.5), wherein enumerated many kind system membrane substances, as " silicon dioxde solution " or " silicon-dioxide precursor solution " in described these 3 parts of Chinese invention patent applications.The 2nd part is " colloidal sol of silicon dioxide anti-pollution layer of polished glazed tile surface-gel process preparation method " (application number: CN200610003420.0), explain clearly that wherein colloidal sol-the gel process that just is based on silicon-dioxide (being commonly called as silicon sol) prepares the surface soiling film.The 3rd part is " quartzy siliconising terrazzo and production technique thereof " (application number: CN200510031493.6), though wherein do not make clear fully is to rely on what filmogen on earth, but the personage of this area has reason to judge, just this patent application right requires mentioned " silicate powder " in 2 just may provide enough filmogens to form this patent application right and requires " ... final formation ... silicon-dioxide top layer " described in 1 (the 2nd～3 row); In other words, this patent application be by certain or certain class in fact not openly the silicate of composition form the silicon-dioxide top layer by hydrolysis reaction; And it is cognitive according to specialty, in the middle of existing inorganic chemistry knowledge, although silicate material has in fact constituted about 80%～90% of crust materials, but, in the middle of the silicates material of so huge kind and quantity, thereby can there be obvious hydrolytic action to produce hydrolysis-gelling reaction, forms gum material with water, synthetical two classes are only arranged in fact: silicate cement, wherein be rich in the calcium-silicate composition of mol ratio complexity in calcium oxide-silicon oxide binary system; And based on the alkali silicate (can comprise ammonium silicate on the pure chemistry meaning) of alkalimetal oxide-silicon oxide binary system.
As for natural volcanic ash class, though having hydration activity and show in geologic process, it enlivens, examining closely from the practical standpoint of this patent application then obviously is too to be partial to inertia.Chemistry of cement was studied very fully, and indicate, the product of hydrated reaction of cement, can not there be silicon-dioxide, under the strong alkaline environment of its high oxidation calcium, formedly be the binary calcium oxide-silica gel of complicated mol ratio and often change into the grain state that the binary calcium oxide-silica gel of described this state obviously can not cause this patent application described " ... final formation ... silicon-dioxide top layer " (this patent application right requires 1 (the 2nd～3 row)).Therefore, can reach purpose that this patent application requires " ... final formation ... silicon-dioxide top layer ", the result of Fen Xiing should just be based on alkalimetal oxide-silicon oxide binary system alkali silicate (also can expand on the pure chemistry meaning and comprise ammonium silicate) in theory, be designated hereinafter simply as alkali silicate, can use formula M
2OmSiO
2Represent that wherein M is the main group element basic metal of the 1st family in the periodic law of elements, pairing cation form is shown M
+, also can expand to herein and comprise NH
4 +Ammonium ion, and m represents SiO
2To M
2The mol ratio of O.Document " fine ceramics technology, compilings such as Xu Weixin, press of Shanghai Communications University; September in 1989 the 1st edition, P102 " has been introduced water glass stiffening agent and sclerosis chemistry: Sodium Silicofluoride is slightly soluble in water, and hydrolysising balance of its dissolving saturated solution is acid, PH=3, precipitated silicic acid gel simultaneously.And the acid product that hydrolysis like this caused reduces the pH value of water glass significantly, thereby makes water glass lose colloidal stability, also forms the gel state material and solidifies.Such mechanism, can disclose well: (application number: CN200510031493.6), why used hardening accelerator composition wanted fluorine-containing Magnesium Silicate q-agent or Sodium Silicofluoride (claim 1 the 4th to the 5th row), why will rather than do not contained silicic anhydride (that is SiO with mixing " silicate powder " in resin (in the claim 2 the 2nd, d bar) in patent application " quartzy siliconising terrazzo and production technique thereof "
2) the non-silicate class be packed in the top top layer.
