Description

新型建材表面电子辐射固化涂料Electron Radiation Curing Coatings on the Surface of New Building Materials

本发明涉及一种新型建材表面电子辐射固化涂料。The invention relates to a novel electronic radiation curing coating on the surface of building materials.

目前,随着高层建筑的日趋增多,室内外的各类装潢业也日趋兴旺;现大多采用在壁上多彩喷塑技术或贴装饰性墙纸、壁布作为墙壁表面装饰,但这些装饰材料易脱落、变色,且采用多彩喷塑技术时,喷塑的涂料本身散发着异味并有一定的毒性对人体极为有害,另外还不具有防火、隔热、耐腐蚀的作用;目前新型防火、耐水洗、耐腐蚀的建筑装饰材料的需求随着消防的严格要求也日趋增长;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,表面为阻燃层。该纸膜层贴附的表面需可阻燃,但其粘接层粘接较繁琐,粘接后表面不易平整,易起泡,且怕水洗。随着科学技术的发展,核技术的应用也日趋增多。目前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、日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Klev工厂生产了一种EB涂层固化木板,其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;该配方配制的涂料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后辐照时,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技术,其涂层配方是由丙烯酸树脂35%、丙烯酸聚氨酯15%、丙烯酸丁酯32%、丙烯酸4%,丙烯酸环己酯9%、丙烯酸2-乙基乙酯5%组成;该配方配制的涂料刷涂于金属板表面时,其柔性好,加工时固化速度快;但其光泽度差、耗氮量大。At present, with the increasing number of high-rise buildings, all kinds of indoor and outdoor decoration industries are also becoming more and more prosperous; now most of them use colorful spray technology on the wall or paste decorative wallpaper and wall covering as wall surface decoration, but these decorative materials are easy to fall off. , discoloration, and when the colorful spray technology is used, the spray paint itself emits peculiar smell and has certain toxicity, which is extremely harmful to the human body. In addition, it does not have the functions of fire prevention, heat insulation, and corrosion resistance; The demand for corrosion-resistant building decoration materials is also increasing with the strict requirements of fire protection; a "magnesite flame-retardant decorative board" is disclosed in China 93215903.6, which is based on magnesite board and coated with Brush one layer of adhesive layer, paste a layer of paper film layer on the upper layer of the adhesive layer, the paper film layer can choose color patterns arbitrarily, and attach a surface layer on the paper film layer, the surface is a flame-retardant layer. The surface to which the paper film layer is attached needs to be flame retardant, but the bonding of the adhesive layer is cumbersome, and the surface is not easy to be smooth after bonding, easy to foam, and is afraid of washing. With the development of science and technology, the application of nuclear technology is also increasing. At present, radiation processing technology is the most widely used and most active emerging processing field in nuclear technology. It formed some large-scale industrial sectors in the 1970s. 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) , Germany), Russia, Japan, Indonesia and other countries have manufacturers of new building materials such as radiation processing wood boards, plywood boards, silicon cement boards, gypsum boards, and iron boards. An EB-coated cured wood board was produced at the Slmferopol and Klev factories in Russia, the formulation of which was trimethylolpropane diallyl ether and modified unsaturated polyester 50%, triethylene glycol dimethacrylate 40% and 10% triethylene glycol phthalate; the coating prepared by this formula consumes less nitrogen when it is irradiated on wood boards, but the residual amount of oxygen is high, the radiation dose is large, and the curing speed is high. slow. The wood coating formula recommended by Sartomer in the United States is composed of 12% acrylated amino ester, 20.15% propoxylated neopentyl glycol diacrylate, 22% ethoxylated trimethylol propane triacrylate, ethoxylated ethoxyethyl 7% acrylate, 35% titanium oxide, and 3.85% additives; the coating prepared by this formula has a fast curing speed when it is applied on wood and then irradiated, 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. For example, the metal plate coating curing technology developed by Shanghai University of Science and Technology, its coating formula is composed of acrylic resin 35%, acrylic polyurethane 15%, butyl acrylate 32%, acrylic acid 4%, cyclohexyl acrylate 9%, It consists of 5% ethyl ethyl ester; 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.

本发明的目的是为了提供一种无毒、无刺激、无需溶剂、可刷、喷、涂、其所需固化环境优异、涂膜性能优良、表面光洁度高、耐水洗、耐污、耐腐蚀、节能、无污染的新型建材表面电子辐射固化涂料。The purpose of the present invention is to provide a non-toxic, non-irritating, solvent-free, brushable, sprayable, coating, excellent curing environment required, excellent coating performance, high surface finish, washable, stain-resistant, corrosion-resistant, Energy-saving and pollution-free electronic radiation curing coating on the surface of new building materials.
