The invention relates to an all-in-one water-borne inorganic-organic hybrid architectural coating and a preparation method thereof, wherein the all-in-one water-borne inorganic-organic hybrid architectural coating is prepared by taking a compounded product of a water-borne inorganic film-forming matter and an organic polymer emulsion as a base material through the steps of adding various pigments / fillers and auxiliaries into the base material, then carrying out beating, grinding and paint mixing on the obtained mixture. In the invention, through a Si-O-Si polymer net structure which can be formed by compounding alkali metal silicates and small-particle-size silica sols in the process of film forming, the early water resistance of a paint film is greatly increased, and the eventual hardness, scraping resistance and stain resistance of the paint film are greatly increased; and through adding the organic polymer emulsion, the film-forming performance of the coating can be improved, and the defects that the traditional two-component inorganic coating is easy to crack, bad in decorative properties, poor in storage stability, and the like are overcome. The coating prepared by using the method disclosed by the invention has various functions of environmental friendliness, non-toxicity, thermal insulation, ultra scrubbing resistance, abrasion resistance, yellowing resistance, ageing resistance, fouling resistance, good air permeability, sound insulation, and the like.

The invention provides a preparation method of annular phosphonate or annular organic phosphate flame retardant. The steps are that (1) trimethylolpropane and trimethyl phosphate or triethyl phosphate are taken as the material, and react to synthesize into midbody under the condition of catalyzer; (2) phosphonate or organic phosphate is added into the midbody and is heated, and then the product of annular phosphonate or annular organic phosphate flame retardant can be obtained. The phosphite ester is selected from trimethyl phosphate and triethyl phosphate. The phosphonate is selected from dimethyl-phosphine and diethyl ethyl phosphine. The organic phosphate is selected from trimethyl phosphate, triethyl phosphate, phosphate propyl, tributyl phosphate and tricresyl aromatic ester. The invention overcomes the shortcomings of the prior art, the new preparation method of annular phosphonate or annular organic phosphate flame retardant is environment-friendly, solution is not needed, and the operation is simple. The termination product has excellent color and luster, low acid value and excellent viscosity; and does not need additional decoloration.

Described is a way to reduce solvent usage in solvent-dominated oil recovery processes through the use of an emulsion. Injection of an emulsion into an oil reservoir is performed as an alternative or supplement to solvent injection to minimize solvent usage per unit amount of oil recovered. The emulsion may contain solvent and the solvent may form an external-phase of the emulsion. A solvent-external emulsion may be injected and formed using an aqueous liquid or a gas as the internal phase. The emulsion may be an aqueous-external, vapor-internal emulsion with solvent being injected separately or simultaneously. Polymer may be added to viscosify the emulsions and use them for flow diversion in a solvent-dominated process.

The invention discloses an enamel glaze which belongs to the technical field of ceramic materials, and the enamel glaze comprises a colored glaze basic glaze, an enamel glaze basic glaze and coloring pigments. The invention further discloses a preparation process of the enamel glaze and an application of the enamel glaze. The preparation process can improve the firing temperature of the enamel colored glaze, expand the firing range of the glaze, improve the viscosity of the enamel colored glaze and ensure that coloring metal oxides can not be diffused or the color can not be dimmed due to the flowing of the glaze by optimizing the formula of the enamel colored glaze, adopting an appropriate amount of zinc oxide for replacing heavy metal flux materials, such as lead oxide and the like, integrating the applicable color development performances of a variety of coloring materials and introducing a rare earth compound of yttrium oxide. The preparation process can further ensure that the coloring metal oxides in the enamel glaze can not be oxidized by oxygen or water vapor in the air through the way of underglaze color, thereby further ensuring that a product can not change the color or fade forever, closing heavy metals contained in the coloring oxides for avoiding solventing-out and solving the problem of heavy metal pollution.

The invention discloses a water-based mortar modifier, its preparation method and application. The modifier comprises the following preparation raw materials by mass: 10-20% of polyether polycarboxylic acid water reducing agent, 0.1-10% of air entraining components, 1-20% of coagulation retarding components, 0.1-2% of water retention components and 60-85% of water. The polyether polycarboxylic acid water reducing agent is prepared by the method of: dissolving an enol polyether macromonomer, acrylic acid, and maleic anhydride in water, conducting heating to raise the temperature to 60-70DEG C, then adding a persulfate water solution dropwisely, carrying out heat preservation under 60-65DEG C for 2-4h, then performing cooling to a temperature of 45DEG C, and adjusting the pH value of the system to 7-8, thus obtaining the polyether polycarboxylic acid water reducing agent. The modifier provided in the invention can form a protective film on a cement particle surface, and at the same time can produce uniform and tiny bubbles, as well as reduce the friction between the particles in the system, thus effectively improving the workability and plasticity of the mortar system. Furthermore, the mortar modifier provided in the invention is a water-based multifunctional building mortar modifier, and is convenient to use. Doping of the modifier can significantly improve the workability and vicidity of mortar, and can maintain the properties effectively for 8-16 hours.
