Thus, the furniture color of the wood products applied by the glaze can keep constant. The water-based glaze has the advantages of high coloration effect, high transparency, high layering sensation and moderate drying time, and is very convenient for on-site construction.

The invention provides black glass fiber and a preparation method thereof. The black glass fiber prepared by virtue of the preparation method contains SiO2, Al2O3, CaO, MgO, B2O3, Fe2O3, TiO2, MnO2 and K2O+Na2O. The black glass fiber is prepared through direct wiredrawing in a preparation process, and secondary dip dyeing is omitted, so that the problems in the prior art that the dyeing is not uniform, the dyeing adhesive force is poor and the fiber is easy to fall in a secondary dip dyeing process are solved. The preparation method provided by the invention has the beneficial effects that the prepared black glass fiber is low in melting temperature and high in acid-base resistance, and the main raw material is basalt which is widely distributed, high in reserve and low in cost, so that the production cost is greatly lowered.

The invention discloses a method for preparing fluorophlogopite compound titanium dioxide. The method comprises the steps of: soaking fluorophlogopite powder in water to obtain mixed solution, adding oxalic acid to adjust the pH value to be between 2 and 3, and then adding a nonionic surfactant; then adding titanium tetrachloride and stirring, and stopping adding and preserving heat for a period of time when the hue of the mixed solution turns blue, wherein titanium metal can be cladded on the surface of fluorophlogopite through the process; and then performing filtration treatment to obtain primary raw materials of the fluorophlogopite compound titanium dioxide, and then performing drying and calcination treatment to finally obtain a finished product of the fluorophlogopite compound titanium dioxide. The fluorophlogopite compound titanium dioxide prepared by the method can be used for coatings, and the coatings have high whiteness (can reach over 99.8), bright and clean surfaces as well as good high temperature resistance and weather resistance, and can never change color and fade. The fluorophlogopite compound titanium dioxide also has the characteristics of good electrical insulating property, antistatic performance, acid and alkali corrosion resistance, strong coloring power and the like, and is simple in processing technology and low in cost.

According to the present invention, a novel cloth art curtain fabric is disclosed; the fabric has characteristics of soft texture, strong coloring capability, and simple preparation process; with the fabric of the outer layer, ultraviolet radiation can be effectively obstructed; and with the unique antibacterial deodorization fibers in the fabric of the middle layer, bacterial invasion can be prevented during convection of indoor air and outdoor air, and odor gas molecules in air can be absorbed, and are voluntarily decomposed through illumination so as to create a clean and comfortable indoor environment.

The invention discloses stable permeation composite type rust coating and a preparation method thereof. The stable permeation composite type rust coating is formed by mixing epoxy resin E-44, xylene, absolute ethyl alcohol, aluminum triphosphate, zinc phosphate, iron oxide red, zinc molybdate, penetrant epoxy phosphate, a dispersing agent, a defoaming agent and a curing agent. Antirust agents are aluminum triphosphate, zinc phosphate and zinc molybdate. Triphosphate radical ions can have a stronger chelating ability with various metal ions, and a passive film is formed on the surface of a coated object; zinc phosphate and ferric ions have a higher condensation ability, phosphate anions react with iron anodes, a firm protection film with ion phosphate as a main body can be formed, and the compact purification film is insoluble in water, high in hardness and excellent in adhesive force; zinc molybdate can release molybdic acid ions, a composite insoluble substance formed on the surface of steel has an anti-rust effect; in this way, the anti-corrosion performance of the coating is excellent through the synergistic effect of the components.
