The present invention discloses a smooth and elastic finishing agent for nylon-cotton fabrics, and a preparation method thereof. The smooth and elastic finishing agent for nylon-cotton fabrics is prepared by the following components in weight percentage: 30-45% of modified terpolymer block silicone oil, 10-20% of isomeric fatty alcohol-polyoxyethylene ether, 0.05-2.5% of glacial acetic acid and 35-55% of water. According to the technical scheme of the invention, the synthesis of end epoxy silicone oil is conducted according to the alkali process route, so that the generation of a large amount of solid waste residues is avoided. Meanwhile, the method is simple in process, and the end epoxy silicone oil can be obtained in one step. Moreover, an obtained product is better in sliding feeling and delicate feeling compared with products obtained through the conventional acid method.

The invention relates to emulsifiable paste with inflammation diminishing, itching relieving and antibacterial effects and a preparation method thereof. The emulsifiable paste with the inflammation diminishing, itching relieving and antibacterial effects is prepared from the following components in parts by weight: 1.0 to 5.0 percent of menthol, 5.0 to 10.0 percent of camphor, 1.0 to 5.0 percent of methyl salicylate, 0.5 to 1.0 percent of borneol, 0.1 to 0.5 percent of thymol crystals, 0.01 to 0.05 percent of beclomethasone, 6.0 to 10.0 percent of an emulsifier Gelot 64, 3.0 to 6.0 percent ofoctadecanol, 4.0 to 7.0 percent of monoglyceride and the balance of purified water. The emulsifiable paste of the formula is low in irritation to the skin, is not oily and has the characteristics of easiness in cleaning, high stability of effective components and relatively long preservation time; according to the manufacturing method disclosed by the invention, a homogenous phase body is formed by the emulsifier Gelot 64, the octadecanol, the monoglyceride and the water, so that the process is simplified; the emulsifiable paste further has the advantages of higher stability of the effective components and longer validity period.

The invention discloses a method for detecting impurity components in alpha-alumina, which belongs to the glass manufacturing field, and sequentially comprises the following steps that: an alumina sample is weighed and is placed into a NO. 1 digestion tank and a NO .2 digestion tank, and then a digestion agent is added into the NO. 1 and the NO. 2 digestion tanks; a sample blank experiment is done for a NO. 3 digestion tank, a NO. 4 digestion tank, a NO. 5 digestion tank and a NO. 6 digestion tank; digestion is simultaneously carried out in each digestion tank; the digestion tanks are heated so as to remove partial acid; the NO. 1, the NO. 2 and the NO. 3 digestion tanks are transferred into a volume bottle to so as to fix the volume; the NO 4, the NO. 5 and the NO. 6 digestion tanks are transferred into a volume bottle, standard solution Y with appropriate quantity is respectively added into the NO. 4 digestion tank to be used as an inner calibrated standard solution; detected element standard solution with appropriate concentration is added into NO. 5 and NO. 6 digestion tanks to fix the volume; and the contents of impurity components of the alumina are measured through an internal standard method by placing the mixed solution on inductively coupled plasma (ICP). The method has the advantages that the analysis process is simple, the electric power cost is low, a crucible is difficult to damage, samples can be completely dissolved, the components are difficult to lose, and the matrix interference is low.

The invention provides a direct injection molding chemical micro-foaming polypropylene composite material and a preparation method thereof. The composite material is prepared by the steps of mixing a polypropylene composite material and a sodium bicarbonate foaming agent according to a certain compounding ratio and performing injection molding and forming by twice-open molding technique, wherein the polypropylene composite material is prepared from the following components in parts by weight: copolymerized polypropylene (PP) 55-65 parts, high density polyethylene (HDPE) 10-20 parts, ultra-high molecular weight polyethylene (UHMWPE) 5-10 parts, talc powder 15-20 parts, an antioxidant 0.2-0.4 parts, a lubricant 0.5-1 parts, a light stabilizer 0.5-1 parts, and other assistant 0-1 parts. Through a proper compounding ratio of PP, HDPE and UHMWPE, the molecular weights in the composite system are reasonably distributed, the molecular chains are entwisted with each other, the chain segments of different molecular weights are disorderly entwisted to form a three-dimensional reticular network structure and achieve excellent compatibility, thereby improving the molten mass strength of linear polypropylene and obtaining the micro-foaming material with small and fine pores. The composite material provided by the invention has low cost and excellent mechanical properties, is convenient in operation, achieves good weight reduction effect, effectively reduces the weight of workpieces, and realizes light weight of parts.
