The invention provides a directional freezing method for continuously producing polysilicon ingots, relating to an uniform polycrystal material which takes material or shape as characteristics and possesses of a certain structure. The invention provides a directional freezing method for continuously mass production of polysilicon ingots in the process of producing solar energy-level polysilicon by metal silicon in the metallurgy process and a device adopting the method. Empty graphite molds are arranged according to the axial space order and driven to move forward by a furnace vehicle, and the empty graphite molds are preheated in the preheating area; liquid silicon undergoing melt refining is put in the empty graphite molds after preheating; the liquid silicon is kept warm in a high-temperature area of a hearth and enters an intermediate-temperature area; from the high-temperature area to the intermediate-temperature area, the liquid silicon are gradually directionally frozen in graphite molds; frozen silicon is cooled down to room temperature below a revolving track protective cover in the graphite molds to obtain directionally frozen polysilicon ingots. The directional freezing continuous track furnace for continuously producing polysilicon ingots is provided with a furnace body, a furnace hearth, a furnace vehicle track, a furnace vehicle, a front auxiliary cart, a back auxiliary cart, a revolving track, a propelling device and a power supply and temperature control system.

The invention provides a latex type amphiphilic polymer resin, which is formed by polymerizing unsaturated acid alkyl, methyl methacrylate, styrene, butyl methacrylate, butyl acrylate, hydroxypropyl methacrylate, ethylene glycol methacrylate, acrylamide, diacetone-acryloamide and other monomers. The paint which takes the latex type amphiphilic polymer resin as a main film forming material and combines with inorganic polymer stuffing integrates with decorative property, humidifying property, permeability, heat preservation, condensation prevention, water and alkali resistance, bacterium resistance and so on, and can prevent the paint film from dropping off due to multiple kinds of seepage and water condensation of a wall body, so that the paint film is more durable; in addition, the paint has no organic solvent, and is safe and environment friendly.

The invention provides a method for preparing water-borne polyurethane polyacrylate compound emulsion. The method comprises the following steps of: preparing water-borne polyurethane emulsion by using polypropylene glycol, 2,2-dihydromethyl propionic acid and isophorone diisocyanate as main materials; preparing polyacrylate emulsion by polymerizing methyl methacrylate, acrylic acid, butyl acrylate and diacetone acrylamide serving as main materials; and finally, mixing the water-borne polyurethane emulsion and the polyacrylate emulsion to obtain the water-borne polyurethane polyacrylate compound emulsion. The breathable coating produced by using the water-borne polyurethane polyacrylate compound emulsion as a main film-forming material of coatings integrates functions of decoration, humidity regulation, permeability, heat preservation and condensation prevention, water resistance, alkali resistance and the like, overcomes the defect of high energy consumption of conventional air conditioners, simultaneously prevents the falling of films caused by leakage and water condensation of walls, makes the films more durable and has a better application prospect.

The invention provides organic silicon-acrylic ester copolymer emulsion, which utilizes organic silicon, methyl methacrylate, butyl acrylate, unsaturated alkyl acid and methacrylic acid-beta-hydroxypropyl ester as comonomers, utilizes deionized water as solvent, utilizes potassium peroxydisulfate or ammonium persulfate as an initiator and utilizes sodium bicarbonate as a neutralizer, and is prepared by polymerization in the presence of an emulsifying agent. The emulsion introduces the organic silicon into polyacrylate, the rigidness of a copolymer is improved to a certain extent, and cohesion of the copolymer emulsion is improved due to the introduction of a polar group. Interior wall humidity-conditioning paint prepared by the copolymer emulsion serving as a film former integrates multiple functions of decoration, humidity conditioning performance, permeability, insulation and anti-condensation performance, water resistance, alkali resistance, alkali-resistant performance and antibiosis, the paint film is durable and long in service life, and the organic silicon-acrylic ester copolymer emulsion serving as the interior wall humidity-conditioning paint has application prospects.

The invention provides an amphiphilic polymer resin with hydrophilicity and hydrophobicity, which is polymerized by methacrylic acid, methyl methacrylate, butyl acrylate, beta-hydroxypropyl methacrylate, acrylamide, diacetone acrylamide and adipic dihydrazide monomers or the like. The amphiphilic polymer resin can be used as main filming material of paint to combine various cell forming materialsto prepare the paint with decorativeness, humidity adjustment, permeability, thermal insulation, dew prevention, water and alkali resistance and anti-bacterial property, as one multifunctional intelligent breath paint. The product can overcome the defects of traditional air conditioner as high energy consumption and can avoid paint from dropping off wall caused by leakage and water, thereby prolonging the service life of paint, and the invention has wide application.
