The invention relates to the field of nano materials and particularly relates to a mildew-resistant and antibacterial nano-silver decorative laminated board. The mildew-resistant and antibacterial nano-silver decorative laminated board is formed by a decorative veneer and a base material which are bonded by an adhesive layer, wherein the decorative veneer and the base material are dipped by nano aqueous solution; the adhesive layer contains nano-silver substances; the decorative veneer and the base material are made of technical wood; the nano-silver aqueous solution is formed by adopting deionized water as a solvent, adopting nano silver as solute to be dissolved into the deionized water, adopting acrylic resin as a complexing agent and a stabilizing agent to be dissolved into the deionized water, and adding a dispersing agent and a first reducing agent simultaneously; the concentration of nano silver in the adhesive is 75-150ppm; the mass content of flour in solution is 18-45%; environmental-friendly glue comprises the following materials in parts by weight: 40-80 parts of acrylic resin solution emulsion with the solid content being 40-55%, 20-40 parts of acrylic resin powder, 5-20 parts of EVA emulsion with the solid content being 40-60%, 1-4 parts of dibutyl phthalate and 7-13 parts of chlorinated polypropylene or polyolefin substrate adhesive-force promoter. The mildew-resistant and antibacterial nano-silver decorative laminated board has the advantages that the stability and the dispersibility are good and the mildew can be fully resisted.

The invention relates to the field of building materials, and particularly discloses a shield grouting material and a preparation method thereof. The shield grouting material is prepared from the following raw materials in parts by weight: 80 to 120 parts of cement, 180 to 300 parts of fly ash, 200 to 350 parts of sand, 50 to 80 parts of bentonite, 2 to 4 parts of a thickening agent, 0.5 to 1.5 parts of an expanding agent and 0.5 to 3 parts of a water reducing agent, the thickening agent is prepared from silica fume, hydroxypropyl methyl cellulose and diallyl phthalate; the shield grouting material prepared by the invention has a relatively high condensation speed.

The present invention discloses one kind of artificial antigen of dipropyl phthalate, which is prepared with semi-antigen derivative as shown and through diaonization with NaNO2 and concentrated HCl at low temperature to produce corresponding diazonium salt, and the coupling reaction of the diazonium salt with carrier protein. It has the structure as shown. The artificial antigen of the present invention is practical and stable, and has simple preparation process and low cost, and the present invention is easy use in industrial production.

A catalyst component comprising Ti, Mg, Cl, and an electron donor compound having porosity of at least 0.2 cm³/g and characterized by the fact that it further comprises Cu oxide, with the proviso that when the electron donor compound is selected from esters of phthalic acids, the porosity is of at least 0.45 cm³/g.
