The invention discloses a traditional Chinese medicine compound transdermal gel preparation having the effects of inhibiting inflammation and suppressing pains, and a preparation method thereof. The gel preparation is composed of a traditional Chinese medicine compound composition having the effects of inhibiting inflammation and suppressing pains, a gel matrix and a transdermal absorption penetration enhancer. The medicine composition takes aconite extract and white peony root extract as active ingredients, and has a significant synergic effect in aspects of inhibiting inflammation and suppressing pains. A curative effect is obviously superior to that of aconite total alkaloids or white peony root total glucosides being used individually. The medicine can reach lesions directly by delivering the preparation transdermally. At the same time, security can be further increased. Animal pharmacodynamic tests of the gel preparation show that pharmacological actions for inhibiting inflammation and suppressing pains of the preparation are obvious and definite, thereby providing a pain-relieving compound transdermal preparation which has better clinical curative effect and is more convenient for use.

The invention provides a preparation method of a high-temperature-resistant coating with a self-cleaning performance, and belongs to the technical field of chemical engineering. The high-temperature-resistant coating with the self-cleaning performance is prepared by spraying through taking a superhydrophobic modified cobalt blue pigment as a coloring agent and silicone resin as a film-forming substance. The prepared coating also has superhydrophobic performance after being calcined at 380 DEG C for 2 h; and after the coating is calcined at 800 DEG C, a film formed by the coating becomes hydrophilic, but the surface of the film is complete and smooth, so the coating can be used as a heatproof coating.

The invention relates to an industrial storage-resistant, anti-caking fine ammonium perchlorate and a preparation method thereof. The preparation method comprises the steps: mixing an anti-caking agent in an ammonium perchlorate crude material, wherein the anti-caking agent is added in an amount of 0.5-2% of the mass of the ammonium perchlorate crude material; pulverizeing the material by a jet mill to obtain the storage-resistant, anti-caking fine ammonium perchlorate, wherein the anti-caking agent is a mixture of nano-oxide, aziridine compounds and ester plasticizers, the ratio of each component is that: the mass of the nano-oxide is 100 parts, the mass of the aziridine compound is 40-80 parts, and the mass of the ester plasticizer is 40-80 parts. The method improves the storage-resistant and anti-caking property of fine ammonium perchlorate.
