The invention discloses a high-strength lifting tool head for buildings, which is prepared by a silica sol casting process and comprises the main ingredients in percentage: 0.35 percent to 0.45 percent of C, 0.25 percent to 0.3 percent of Si, 0.45 percent to 0.55 percent of Mn, 1.1 percent to 1.3 percent of Cr, 0.18 percent to 0.22 percent of Mo, 0.12 percent to 0.15 percent of Ni, 0.4 percent to 0.5 percent of Nb, 0.35 percent to 0.4 percent of W and the balance Fe and trace impurities. The invention discloses the high-strength lifting tool head for buildings, which has the advantages that the ingredient preparation is reasonable, the preparation process is simple and convenient, the cost is moderate, and the integral performance is excellent; and particularly, the performance shown in the strength aspect is superior to that of similar products, so the lifting tool head is more reliable and safer in the use process.

The invention provides a colorful noctilucent shell fabric, which comprises the following ingredients in percentage by weight: 30-50% of nylon 66, 15-25% of spandex and 50-70% of colorful noctilucent silk, wherein the colorful noctilucent silk is obtained by colorful noctilucent master batch and textile fiber at certain ratio with a melt spinning method; and the colorful noctilucent master batch is mainly processed by rare-earth aluminate particles, nanometer accessory ingredient and inorganic and transparent colorful material by the special spinning technology. The colorful noctilucent shell fabric disclosed by the invention has the characteristics that the ingredient preparation of the shell fabric is reasonable, and clothes made of the shell fabric can release various colors under the irradiation of sunlight or at night. The shell fabric has a long noctilucent effect aging, and can automatically adsorb sunlight to supplement energy, the durability exceeds 1000 times, and the colorful noctilucent shell fabric can be widely used.

The invention discloses a method for preparing a paint with good antibacterial and antifungal properties, which comprises the following steps: 1) adding water-soluble polyurethane, synthetic resin emulsion, chemical whitening water, oilseed paint, talcum powder, leveling agent and bentonite to an appropriate amount Disperse in water; 2) Grind the nano-inorganic active material, dispersant and appropriate amount of water; 3) Grind the tangerine peel and bellflower and add the mixed antibacterial agent to 2) for mixing; 4) Add the materials in 3) to 1) Add pigment, silicone oil and rosin oil, and stir; add flame retardant and film-forming agent; concentrate treatment. The preparation method of the paint of the present invention, through the reasonable composition ratio and the cooperation between the antibacterial agent and the various components, the prepared paint can not only actively resist and kill the acquired common bacteria attached to the mahogany furniture, but also has a harmful effect on the human body. It plays a good protective role; at the same time, it can also effectively inhibit or kill the bacteria and mildew inside the solid wood furniture, effectively improving the anti-mold performance of the furniture.

The invention provides a thermal barrier coating which comprises a base layer, a heat-isolation layer and a protective layer. At least one transition layer is arranged between the base layer and the heat-isolation layer. According to the thermal barrier coating, component preparation of the coating is reasonable, the preparation process is simple and convenient, and the transition layer and the heat-isolation layer of the coating contain oxides capable of forming oxidation films easily. Besides, the content of the oxides has gradient changes, so that the thermal barrier coating has good thermal shock resistance. Meanwhile, high-temperature particle erosion resistance is outstanding.
