The invention discloses a preparation method of a metal wire jewelry pendant. The method comprises the following steps of (1) preparation material preparation: a, preparing an embroidery sheet; b, preparing a metal wire embroidery wire; c, preparing a metal framework; (2) metal wire pattern embroidering; (3) jewelry pendant assembling: putting the embroidery sheet with the embroidered metal wire patterns into an accommodating cavity of the metal framework to obtain the jewelry pendant. The method provided by the invention has the advantages that the process is simple and practical; the operation is convenient; the method is suitable for the jewelry pendant using thinner metal wires for national artware processing. The jewelry pendant manufactured by the method cannot be easily abraded, cannot easily generate color degradation, can be easily stored and has high collection artistic value; the metal wire patterns have rich metal luster and has the three-dimensional effects; high attractive effect can be given to the jewelry pendant; the practical value is realized; meanwhile, the collection value is also realized. The pendant is used as the Mongol nationality culture carrier, and is favorable for the propagandization, inheritance and protection of the national artware.

The invention relates to a bio-based art paint and its preparation method and application. The bio-based art paint is prepared from raw materials comprising the following parts by weight: 20-50 parts of bio-based acrylic emulsion, 20-28 parts of pearlescent pigment, and 10-50 parts of water; The glass transition temperature of the acrylic polymer in the bio-based acrylic emulsion is -15°C-0°C. The coating has excellent freeze-thaw resistance and film-forming properties, extremely low VOC, and excellent stain resistance; at the same time, the construction is simple and can be diversified, and it is easy to achieve a strong three-dimensional effect. The surface of the paint film is rich in metallic texture and crystal flash effect. In addition, the use of bio-based raw materials at the same time reduces the dependence on petrochemical raw materials, is highly environmentally friendly, meets people's pursuit of environmental protection and artistic coatings, and has broad application prospects.

The invention relates to a micron-particle high-capacity lithium-ion battery negative electrode material based on conversion reaction and its preparation method and application. The lithium-ion battery negative electrode material is a compound of molybdenum oxide and carbon, and its chemical formula is MoO x / C, x=2~3, where MoO x The content of 60 ~ 90 wt%.

The invention discloses an anti-wear alloy layer based on a high boron iron base and a method for preparing a composite anti-wear part. The anti-wear alloy layer is a high boron iron-based alloy, andcomprises, by mass, 0.2%-0.3% of C, 1.20%-1.60% of B, 0.4%-0.9% of Si, 0.6%-1.1% of Mn, 8.3%-10.5% of Ni, 17.0%-20.0% of Cr, 0.08%-0.15% of Ce, 0.10%-0.15% of Ti, 0.04%-0.08% of N, less than 0.05% ofP, less than 0.05% of S, and the balance Fe and other unavoidable impurities. By adopting an advanced resin sand production line and an electric-furnace smelting technology, surface alloying is achieved through a cast infiltration technology to replace heat treatment surface strengthening, the elements of titanium, zirconium, tantalum and tungsten are evenly mixed with inorganic salt to be fixed in a casting mold, metal liquid is casted, and the composite anti-wear part is obtained after cooling and unpacking. The anti-wear alloy layer based on the high boron iron base and the method for preparing the composite anti-wear part can improve the toughness and the surface hardness of the high boron iron-based alloy anti-wear part, and can prolong the service life of the high boron iron-based alloy anti-wear part.

The invention provides rapid repair paint for reducing the repair chromatic aberration of a car body and a preparation method of the rapid repair paint. The repair paint comprises the ingredients in parts by weight: 20-40 parts of resin, 20-40 parts of additive resin, 5-10 parts of a metal pigment, 10-20 parts of a copolymer, 5-10 parts of a solvent, and 1-5 parts of an additive. The preparation process is simple, through the application of the obtained repair paint, the repair chromatic aberration of the car body can be reduced effectively, and the repair efficiency can be improved; after repair, particles of metal paint looks more three-dimensional, metallic and brilliant, the product performance is excellent, the hardness is equal to and higher than H, and the adhesive force is 0-1 level.
