Abstract
The invention discloses a formula and a preparation method of an organosilicon hydrophobic powder, and relates to the technical field of waterproof agent. The formula comprises the components by the mass fraction: 40-60% of methyl silicic acid, 8-10% of potassium hydroxide, 12-16% of sodium hydroxide, and 14-40% of deionized water. The preparation process comprises the steps: mixing 8-10% of potassium hydroxide and 12-16% of sodium hydroxide, adding into 14-40% of deionized water, dissolving, then adding 40-60% of methyl silicic acid, heating to dissolve, heating up to 90-100 DEG C, after fully dissolving, placing the mixture in a 480 DEG C constant-temperature control box, baking, making the mixture to reach the drying rate of above 99%, then crushing to 300 mesh or more with a full set of stainless steel high-mesh crusher, and thus obtaining the finished product. The organosilicon hydrophobic powder has the advantages of simple preparation method, strong waterproof anti-permeability ability, convenient use, and wide use, fills a domestic blank, and replaces imported products.
Description
Technical field:
The present invention relates to water-resisting agent technical field, be specifically related to a kind of formula and preparation method of organosilicon hydrophobic powder.
Background technology:
Impervious waterproof in construction work is always a problem received publicity, impervious at concrete structures such as vault, dam, swimming pools, and the water-proof repairing aspect of roof, flooring etc., be developed various impervious additive, water-resisting agent and waterproof paint.Although the effect of water proof anti-seepage can be played, but all there is certain problem, traditional pitch craft leakage mending method constructional difficulties, cost be high, affect validity period by ultraviolet only has about 1 year, therefore in buildings waterproof industry, the application of waterproofing agent of organosilicon is increasing trend, waterproofing agent of organosilicon has coating water white transparency, refuse water hydrophobic effect obviously, may be used for the distinguishing features such as metope.Such as, but there is some problems highly paid attention in present waterproofing agent of organosilicon, in extensive use procedure, existing waterproofing agent of organosilicon belongs to liquid product, and transport is inconvenient, and cost increases, liquid silicone water-resisting agent just surface uses water resistance weather resistance bad, range of application is subject to limitation, and therefore, organosilicon hydrophobic powder instead of liquid silicone water-resisting agent, Performance Ratio waterproofing agent of organosilicon is eager to excel, cost is low, easy to use, the effect that purposes is wider.
Summary of the invention:
The object of this invention is to provide a kind of formula and preparation method of organosilicon hydrophobic powder, its preparation method is simple, and water proof anti-seepage ability is strong, and purposes easy to use is wide, fills the domestic gaps, and replaces imported product.
In order to solve the problem existing for background technology, the present invention by the following technical solutions: its preparation method is: its formula is: massfraction is 40-60% methyl siliconic acid, 8-10% potassium hydroxide, 12-16% sodium hydroxide, 14-40% deionized water;
Its Making programme is: the potassium hydroxide of 8-10% and the mixing of 12-16% sodium hydroxide are added in 14-40% deionized water and dissolve, then 40-60% methyl siliconic acid is added, 90-100 DEG C is warming up to after carrying out heating for dissolving, thermostatically controlled tank mixture being put into 480 degree after abundant dissolving toasts, after making mixture reach the dryness factor of more than 99%, carrying out pulverizing with a complete set of stainless steel height order number pulverizer, namely reach more than 300 orders be finished product.
The present invention has following beneficial effect: its preparation method is simple, and water proof anti-seepage ability is strong, and purposes easy to use is wide, fills the domestic gaps, and replaces imported product.
Embodiment:
This embodiment takes following technical scheme: to be its preparation method be for its preparation method: its formula is: massfraction is 40-60% methyl siliconic acid, 8-10% potassium hydroxide, 12-16% sodium hydroxide, 14-40% deionized water;
Its Making programme is: the potassium hydroxide of 8-10% and the mixing of 12-16% sodium hydroxide are added in 14-40% deionized water and dissolve, then 40-60% methyl siliconic acid is added, 90-100 DEG C is warming up to after carrying out heating for dissolving, thermostatically controlled tank mixture being put into 480 degree after abundant dissolving toasts, after making mixture reach the dryness factor of more than 99%, carrying out pulverizing with a complete set of stainless steel height order number pulverizer, namely reach more than 300 orders be finished product.
This embodiment has following beneficial effect: its preparation method is simple, and water proof anti-seepage ability is strong, and purposes easy to use is wide, fills the domestic gaps, and replaces imported product.
