The invention relates to a preparation method of a 3853 oxide (with the full name of 2, 2, 6, 6-tetramethyl-piperidinooxy stearate), and aims to solve the problem about generation of the product in the market at present. The manufacturing technique of the 3853 oxide adopts and introduces a novel structure, adopts a transesterification route, post-processing adopts oxidation filtering to replace previous water washing, so that waste water discharge is reduced. The product grade is improved through introducing a polymerization inhibitor 701 into a group, and besides, the methyl stearate raw material is low in cost, so that popularization of the photostabilizer market is facilitated.

The invention discloses isotactic polypropylene/tall oil acid/polybutadiene composite sound absorbing cotton and a preparation method thereof. The composite sound absorbing cotton is formed by a top face layer, a back face layer and a cellucotton layer arranged between the top face layer and the back face layer. The top face layer and the back face layer are made of a non-woven fabric material. The composite sound absorbing cotton is characterized in that the non-woven fabrics are prepared by the following raw materials by weight through a melt-blow method: 100 parts of isotactic polypropylene, 1-2 parts of tall oil acid, 8-10 parts of polybutadiene, 5-7 parts of solid paraffin, 1-2 parts of barium stearate, 2-3 parts of aluminium hydroxide, 14-17 parts of diethylene glycol dibenzoate, 1-2 parts of zinc borate, 12-14 parts of dry shells, 7-9 parts of basalt, 3-5 parts of apocynum venetum, 2-4 parts of white peony roots, 1-2 parts of bighead atractylodes rhizome and 4-5 parts of auxiliary. The isotactic polypropylene/tall oil acid/polybutadiene composite sound absorbing cotton has the advantages of being high in tensile property, large in product void rate and good in breathability, and improves the sound absorbing effect of ordinary sound absorbing cotton.

The invention discloses a defoamer containing high-carbon alcohols and a preparation method thereof. The raw materials of the defoamer include 2 to 5 parts of palmitic acid, 0.2 to 0.6 parts of propylene glycol, 4 to 10 parts of n-octanol, 6 to 20 parts of pentaerythritol ester stearate, and 5 to 12 parts of hexacane Alcohol, 12-30 parts of microcrystalline wax, 2.5-7.5 parts of emulsifier, 0.5-3 parts of n-decyl alcohol modified nano-silica, and water; wherein n-decyl alcohol-modified nano-silica is nano-silicon dioxide Obtained by immersing in n-decyl alcohol. The defoamer of the present invention is in the form of an emulsion containing multiple high-carbon alcohols and has defoaming effect. In addition, the n-decyl alcohol-modified nano-silica, as a hydrophobic particle, can cooperate with the oil phase components to further enhance the defoaming effect. In addition, it significantly reduces costs compared to silicone defoamers and polyether defoamers.

The invention relates to the technical field of fine chemical engineering, and concretely relates to a down feather detergent composition. The down feather detergent composition comprises, by weight,30-50 parts of a surfactant, 15-28 parts of tea seed cakes, 10-16 parts of plant ash, 5-15 parts of white carbon black, 3-9 parts of a curing agent, 2-6 parts of an enzyme preparation and 100-150 parts of washing water of rice. The feather down detergent composition uses ethylene glycol stearate, phosphatidylcholine and triglyceride as the surfactant, so the detergency of the down feather detergent composition is improved; the curing agent is added to make the down feather detergent composition stable, so the service life of the down feather detergent composition is prolonged; and the enzyme preparation is added to further enhance the detergency of the down feather detergent composition.

The invention discloses solar cell conductive mixed paste containing polyethylene vinyl acetate. The solar cell conductive mixed paste containing the polyethylene vinyl acetate is prepared by the following raw materials: by weight, A materials 58-61, B materials 24.8-26.8, triethyl citrate 0.2-0.4, octyl epoxy stearate 0.3-0.5, polyethylene vinyl acetate1.8-2.6, poly adipic acid glycol1-2, castor oil 1-2, silane coupling agents KH602 1-2, and organic silicon flatting agents 1-2. Due to the fact that lead is not contained, the solar cell conductive mixed paste containing the polyethylene vinyl acetate completely conforms to the requirements of environmental protection, can be applied to the production of solar cells, and can form strong adhesion on the surfaces of solar cells, and cell photoelectric conversion efficiency is high.

The invention discloses a preparation method of a calcium sulfate whisker floor tile. The method comprises the following process step of preparing an ingredient which is prepared from the following raw materials in parts by weight: 120-140 parts of plastic particles, 11-13 parts of silica gel, 32-35 parts of a plasticizer, 1.4-1.6 parts of a dispersing agent, 9-10 parts of high-strength gypsum, 10-12 parts of titanium dioxide, 2-4 parts of calcium sulfate whiskers, 3-4 parts of dibasic lead stearate, 2.5-4 parts of a coupling reagent titanate, 4-6 parts of kieselguhr and 0.4-0.8 part of a pigment. The calcium sulfate whisker floor tile has an excellent antistatic effect, is free of lead, low in volatility, free of an oil paint or decoration, safe and reliable in a using process, good in wear resistance, moisture-proof, mothproof, corrosion-resistant, light in weight, low in price, waterproof and skidproof, and is more astringent in water, non-slip, good in heat conduction and heat retention properties, uniform in heat emission and heat-resistant.
