The invention relates to a manufacture method of a self-cleaning fabric. The manufacture method comprises the following steps: uniformly mixing polyvinyl chloride, polyoxyethylene-polyoxypropylene block copolymer, epoxy resin, nanometer titania, towel gourd juice, nanometer mica powder and polystyrolsulfon acid, heating to a molten state, adding benzyl butyl phthalate, cellulose ester, nanometer chitin and residual components, uniformly mixing to obtain a modified spinning melt, performing spinning and postprocessing to obtain ultrafine denier fibers, and spinning the spinning fibers to obtain the self-cleaning fabric. By virtue of blending spinning of the combined materials, a hierarchical structure combining a micron structure with a nanometer structure is formed on the surface of the fabric, so that the surface roughness of the fabric is enhanced, and the self-cleaning property and the water and oil repellent performance of the fabric are improved greatly.

The invention discloses a fireproof composite structure glass that can effectively block ultraviolet rays. The glass includes two glass substrates, between which a fireproof layer is stuffed. The fireproof layer comprises, by weight: 50% of methyl methacrylate, 15% of dibutyl ester, 20% of sodium sulfite, 1.3% of zinc oxide (ZNO), 3% of magnesium hydroxide, 0.2% of benzyl butyl phthalate, 10% of acrylamide, 0.1% of ethanol, and 0.4% of 2-hydroxy-4-methoxybenzophenone. By adopting the fireproof layer with the formula, ultraviolet rays can be effectively blocked, good fire resistance can be achieved, and the fireproof layer is unlikely to undergo foaming under a long-term use state, therefore, the light transmission performance is good.

The invention discloses a method for detecting six phthalates in drinking water through liquid chromatography-mass spectrometry, and belongs to the technical field of drinking water detection. The method comprises the following steps: (1) additionally arranging a protection column; (2) measuring conditions and a mode; (3) establishing a standard working curve; (4) detecting to-be-detected drinking water. According to the detection method, a sample is not required to be pretreated and can be directly fed, so that the six phthalates (DMP (Dimethyl Phthalate), DEP (Diethyl Phthalate), DBP (Dibutyl Phthalate), BBP (Benzyl Butyl Phthalate), DEHP (Di 2-Ethyl Hexyl Phthalate) and DNOP (Di N Octyl Phthalate)) in the drinking water are qualitatively and quantitatively analyzed at high speed; the method has the advantages of easiness and convenience in operation, less sampling quantity, low cost, good reproducibility, high stability and the like, is not only suitable for daily environment monitoring and is also suitable for quick screening of pollutants in emergency accidents.

The invention discloses a flame-retardant anti-corrosion paint comprising following ingredients, by weight: 60 to 80 portions of acrylic resin, 30 to 40 portions of melamine resin, 5 to 10 portions of benzyl butyl phthalate, 1 to 4 portions of zinc borate, 3 to 10 portions of antimonony oxide, 1 to 5 portions of N, N-dihydroxyethyldodecyl amide, 1 to 5 portions of zinc sulfate, 20 to 30 portions of mica powder, 22 to 28 portions of heavy calcium carbonate, 1 to 5 portions of polyethylene glycol 200, 0.2 to 0.6 portion of polydimethylsiloxane, 0.2 to 0.6 portion of silicon dioxide, and 70 to 80 portions of water. The flame-retardant anti-corrosion paint possesses excellent flame retardant effent and anti-corrosion effect, and relatively high adhesive force on metal products because of the combination of zinc borate, antimonony oxide, N, N-dihydroxyethyldodecyl amide and zinc sulfate, and the combined effect of the composite antifoaming agent composed of polydimethylsiloxane and silicon dioxide, and the other auxiliary agents.
