Description
本发明涉及一种电子辐射涂层固化轻质镁水泥板及其加工工艺。The invention relates to a light magnesium cement board cured by electron radiation coating and its processing technology.
核技术是当代高新技术之一。辐射加工技术是核技术中应用范围最广、最为活跃的新兴加工领域，它于本世纪七十年代形成了一些规模性产业。目前已有不少成熟的稳定增长的产业部门。由于采用辐射技术加工的建筑材料具有较高的强度和良好的表面化学物理性质，因而采用涂层固化辐射加工建材的技术也应用较多；如在北美(美、加)、西欧(法、意、德)、俄、目以及印尼等国都有辐射加工木板、压合板、硅水泥板、石膏板、铁板等新型建筑材料的厂家。在俄罗斯的Slmferopol和Kiev工厂生产了一种EB涂层固化木板，其涂层的配方是由三羟甲基丙烷二烯丙基醚和改性不饱和聚酯50％、三乙二醇二甲基丙烯酸酯40％、三乙二醇邻苯二酸酯10％组成；该涂层涂在木板上进行辐照时所耗氮量较少，但氧的残余量高、辐照剂量大、固化速度慢。美国Sartomer公司推荐的木材涂层配方是由丙烯酸氨基酯12％。丙氧化新戊二醇二丙烯酸酯20.15％。乙氧化三羟甲基丙烷三丙烯酸酯22％。乙氧基乙氧基乙基丙烯酸酯7％、氧化钛35％、添加剂3.85％组成；该配方配制的涂料涂在木材上辐照时，其固化速度快，但原料难得且价高。国内上海科技大学、四川大学等单位也作过木板、硅水泥板、石膏板等建材的辐射固化研究。如上海科技大学研制的金属板涂层固化材料，其涂层配方是由丙烯酸树酯35％、丙烯酸聚氨酯15％、丙烯酸丁酯32％、丙烯酸4％、丙烯酸2-乙基乙酯5％、丙烯酸环己酯9％组成；该配方配制的涂料刷于金属板表面时，其柔性好，加工时固化速度快；但其光泽度差，耗氮量大。目前用低能(200keV)电子帘加速器，在高O2环境下辐照加工轻质氯镁水泥板的研究尚未见报道。目前，随着高层建筑的日趋增多及各类装潢的日渐豪华，新型防火、耐水洗、耐腐蚀的建筑装饰材料的需求也日趋增长；因而市场上各类复合材料的品种较多，如在中国93215903.6中公开了一种“菱镁阻燃装饰板”，该板材是以菱镁板为基材，在其上涂刷一层粘接层，粘接层的上层粘贴一层纸膜层，纸膜层可以任意选择花色图案，纸膜层的上面贴附一表层，Nuclear technology is one of the contemporary high-tech. Radiation processing technology is the most widely used and most active emerging processing field in nuclear technology. It formed some large-scale industries in the 1970s. At present, there are many mature and stable industrial sectors. Due to the high strength and good surface chemical and physical properties of building materials processed by radiation technology, the technology of coating curing radiation processing building materials is also widely used; for example, in North America (US, Canada), Western Europe (France, Italy) Countries such as Germany, Russia, Russia and Indonesia have manufacturers of new building materials such as radiation-processed wood boards, plywood boards, silicon cement boards, gypsum boards, and iron boards. An EB-coated cured wood board was produced at the Slmferopol and Kiev factories in Russia. The coating formula was composed of trimethylolpropane diallyl ether and modified unsaturated polyester 50%, triethylene glycol dimethyl 40% of acrylate and 10% of triethylene glycol phthalate; the coating consumes less nitrogen when it is applied on the wood board for irradiation, but the residual amount of oxygen is high, the radiation dose is large, and the curing slow. The wood coating formula recommended by Sartomer Company of the United States is composed of 12% acrylate amino ester. Propoxylated Neopentyl Glycol Diacrylate 20.15%. Ethoxylated Trimethylolpropane Triacrylate 22%. It is composed of 7% ethoxy ethoxy ethyl acrylate, 35% titanium oxide and 3.85% additives; when the coating prepared by this formula is applied to wood and irradiated, its curing speed is fast, but the raw materials are rare and expensive. Domestic units such as Shanghai University of Science and Technology and Sichuan University have also done research on radiation curing of building materials such as wood boards, silicon cement boards, and gypsum boards. Such as the metal plate coating curing material developed by Shanghai University of Science and Technology. Composed of 9% cyclohexyl acrylate; when the paint prepared by this formula is brushed on the surface of the metal plate, it has good flexibility and fast curing speed during processing; but its gloss is poor and the nitrogen consumption is large. At present, there is no report on the research on the processing of lightweight magnesium chloride cement board by irradiation with low-energy (200keV) electron curtain accelerator under high O 2 environment. At present, with the increasing number of high-rise buildings and the increasing luxury of various decorations, the demand for new fireproof, water-resistant, and corrosion-resistant building decoration materials is also increasing; therefore, there are many types of composite materials on the market, such as in China. 93215903.6 discloses a "magnesite flame-retardant decorative board". The board is based on magnesite board, and a layer of adhesive layer is painted on it. The film layer can choose the color pattern arbitrarily, and a surface layer is attached on the top of the paper film layer.
