The invention discloses a high-performance de-foaming agent and a preparation method thereof. The high-performance de-foaming agent is prepared from following raw materials in parts by weight: 10-70 parts of mineral oil, 1-10 parts of white carbon black, 5-30 parts of modified silicon polyester, 1-5 parts of fatty acid amide type anionic surfactant, 1-3 parts of nano silicon dioxide and 100-400 parts of de-ionized water. The de-foaming agent can keep good foam elimination and inhibition effects under a lower concentration or a lower temperature and is suitable for eliminating a coating system containing styrene-acrylate, pure acrylic, ethyl acrylate, polyvinyl acetate and butylbenzene emulsion; the high-performance de-foaming agent is particularly used for eliminating foams in the coating system for a building; with regard to a transportation or long-period storage process of coatings, the high-performance de-foaming agent has good compatibility with the coatings so that the system has good stability; the high-performance de-foaming agent has the advantages of rapid de-foaming speed, rapid drying speed, less use amount and good performance for assisting film formation, and does not have the bad consequences of blocking an ultra-filtering film, generating fisheyes, shrinking holes and the like.

A therapeutic agent for tympanites in a ruminant animal, which is characterized by comprising a cashew nut shell oil, a heat-treated cashew nut shell oil, anacardic acid, cardanol, or a combination of anacardic acid and cardanol.

The invention relates to the technical field of daily chemical products and in particular to a clean effervescent tablet with pesticide residue and bacteria removing effects and a preparation method of the clean effervescent tablet. According to the preparation method disclosed by the invention, a specific surfactant is combined with a special wet granulation process, so that the feasibility of the production process is ensured. The clean effervescent tablet has the advantages that no dryness or stickness is caused; the adhesion of foam to the surface of a disintegrating agent can be inhibited, the disintegration speed is increased and an effervescent effect is quickly exerted; in the disintegration and dispersion process, the efficient alkaline supplementing effect on a solution system is realized by synergizing a bacteria remover with an alkali-source supplement, fruit wax and pesticide left on vegetables and fruits can be effectively removed, and the aims of effectively removing escherichia coli and staphylococcus aureus are achieved. By using the alkali-source supplement with a special structural form, metal ions in the water body and on the surface of the vegetables and the fruits can be effectively chelated, the effects of softening the water body and chelating the metal ions are realized, and the deposition of calcium scales on the surfaces of cleaned materials is prevented; in addition, a variety of calcium scales or stains are dispersed, so that secondary pollution to tableware, the fruits and the vegetables caused by deposition is prevented.

The invention discloses a corrosion-resistant super-hydrophobic heat-reflecting coating and a preparation method thereof, which is composed of the following raw materials: modified nano-TiO2, modified nano-SiO2, micro-TiO2 and / or SiO2, fluorocarbon resin, solvent, curing agent, defoamer, wetting and dispersing agent and leveling agent. After the present invention is tested, the thermal reflectance of the obtained product reaches more than 90%, and its water contact angle reaches more than 145°, which can meet the requirements for the coating in the harsh outdoor environment.

The invention discloses a low air-entraining viscosity reducing polycarboxylic water reducer which is formed by free radical polymerization of an alkyl phosphotriester mixture, TPEG and unsaturated carboxylic acid under the action of an initiator and a chain transfer agent. By introducing an alkyl phosphotriester monomer containing two double bonds to a main chain, molecules of the obtained polycarboxylic water reducer are of heterocyclic multibranched structures, so that the thickness of a polycarboxylic water reducer adsorption layer is increased, the plastic viscosity of concrete can be remarkably reduced, and meanwhile, by introducing the phosphotriester structure into the molecules of the polycarboxylic water reducer, the foaming property of the obtained polycarboxylic water reducer can be effectively improved and the air entraining property thereof can be reduced. The low air-entraining viscosity reducing polycarboxylic water reducer prepared by the invention is low in dosage and high in water reducer rate, the air entraining property of the low air-entraining viscosity reducing polycarboxylic water reducer can be reduced, the strength and durability of the concrete are improved while the viscosity of high grade concrete is remarkably reduced, and the raw materials are low in cost, the reaction condition is mild, and the low air-entraining viscosity reducing polycarboxylic water reducer is suitable for being popularized and applied.
