    怎样才能提升我国环氧地坪漆施工技术

    目前发达国家如美国、日本、法国等的环氧地坪漆产品和工程技术已相当成熟,主要的材料种类为两大类:一是环氧树脂类。作为最早应用于环氧地坪的树脂类材料,其技术最成熟亦是比重最大的品种。国外以无溶剂系统为主,少量使用水性系统,溶剂型系统材料非常少,多数材料公司已不生产溶剂型材料。二是丙烯酸(交联)类材料,是以甲基丙烯酸类单体聚合而成的不饱和体系。该类材料具有优异的耐候性,可用于室外环境,同时由于快速交联反应使其施工周期大为缩短,特别是在摄氏零度以下亦可较好固化,故在较冷的环境中也可施工。

    At present, floor paint products and engineering technology in developed countries such as the United States, Japan, France and so on have been quite mature. The main materials are divided into two categories: one is epoxy resin. As the earliest resin material used in flooring, its technology is the most mature and the largest proportion. In foreign countries, solvent-free systems are mainly used, and a small amount of water-based systems are used. Solvent system materials are very few. Most materials companies have not produced solvent-based materials. The two is acrylic acid (crosslinking) material, which is an unsaturated system polymerized by monomers of methacrylic acid. This kind of material has excellent weatherability and can be used in outdoor environment. At the same time, because of the rapid cross-linking reaction, its construction period is greatly shortened, especially under zero degree Celsius, it can be solidified better, so it can also be used in cold environment.

    国内环氧树脂地坪材料及技术如何求得突破?业内专家认为,关键是围绕材料做好文章。尽管我国廉价劳动力现状还会持续,但劳动力成本呈上升趋势已是不争的事实,尤其是较发达的东部地区;同时溶剂型成本的大幅提升,达到历史上的最高点,因此无溶剂系统材料的优势会逐渐显现。

    How to break through the domestic epoxy resin floor materials and technology? Industry experts believe that the key is to make good articles around materials. Although the current situation of cheap labor force in China will continue, it is an indisputable fact that the labor cost is rising, especially in the more developed eastern region. At the same time, the solvent-based cost has been greatly increased, reaching the highest point in history, so the advantages of solvent-free materials will gradually emerge. 树脂类地坪材料与国际类似,同样以环氧类材料为主,但多为溶剂型环氧,估计约占地坪材料的70%左右,丙烯酸(交联)类材料在国内使用的较少。除防腐蚀目的的乙烯基材料外,聚氨酯类材料中基本上全部为溶剂型系统,一般含溶剂30%~40%,以聚酯和聚醚聚氨酯为主,大多用于薄涂地坪,几乎没有无溶剂产品和水性产品。以上两类溶剂型产品占了国内地坪材料的绝大部分。

    Resin floor materials are similar to the international ones, mainly epoxy, but mostly solvent-based epoxy, accounting for about 70% of the floor materials, acrylic (cross-linked) materials used less in China. Except for vinyl materials for anticorrosion purposes, polyurethane materials are mostly solvent-based systems, generally containing 30% to 40% of the solvent, mainly polyester and polyether polyurethane, mostly used for thin-coated floor, almost no solvent-free products and water-based products. The above two types of solvent products account for the vast majority of domestic floor materials.

    聚氨酯类地坪材料是另一大材料。据专家介绍,聚氨酯类材料的发展相对环氧树脂类较晚,因此其制造技术和施工技术相对比较难控制,但近几年因其优异的性能获得了越来越广泛的应用。聚氨酯材料的各项性能具有可调节性,既有弹性体,又有类似环氧硬度材料,耐有机酸和有机溶剂等性能优于环氧,而且具有环氧不可比拟的柔韧性,在机械制造、食品加工等行业应用广泛。国外聚氨酯地坪材料象环氧一样,以无溶剂系统为主,少量为水性系统。

    Polyurethane floor material is another big material. According to experts, the development of polyurethane materials is relatively late than epoxy resin, so its manufacturing technology and construction technology is relatively difficult to control, but in recent years because of its excellent performance has been more and more widely used. The properties of polyurethane materials are adjustable, both elastomer and similar to epoxy hardness materials. The resistance to organic acids and organic solvents is superior to epoxy, and the flexibility of epoxy is incomparable. It is widely used in mechanical manufacturing, food processing and other industries. Polyurethane flooring materials abroad, like epoxy, are mainly solvent-free systems, and a small number of waterborne systems.

    此外,环氧树脂地坪材料还应在材料细分和材料研发上有所突破。专家介绍,在材料的细分方面应向更加专业化和个性化方向发展。目前很多公司的产品是“万金油”,用在什么地方都可以,但工业生产是多变的过程,工艺要求千差万别,这就要求材料更加有针对性和个性化,以期最大程度发挥长处、避其缺陷。在材料研发上应在基础研究上做更多工作,改变目前仅凭经验就大胆使用的现状。同时在选择原材料、配方研究、工程结构等方面应科学化,以减少工程问题的出现。

    In addition, epoxy floor materials should also be breakthroughs in material subdivision and material research and development. Experts said that the subdivision of materials should be more professional and personalized. At present, many of the company's products are "ten thousand gold oil", can be used anywhere, but industrial production is a changeable process, the process requirements vary greatly, which requires more targeted and personalized materials, in order to maximize their strengths and avoid its shortcomings. More work should be done on basic research and development of materials to change the current situation of bold use based on experience alone. At the same time, the selection of raw materials, formula research, engineering structure and other aspects should be scientific to reduce the occurrence of Engineering problems.
