青羊区环氧地坪漆分析地坪涂料现状
环氧地坪涂料具有无接缝、整体装饰性好、表面光洁、易于清洁,以及物理机械性能和耐化学品性能优良,价格适中,施工简便,维修方便等诸多特点。另外,地坪涂料还可根据特殊需求,赋予地坪防静电、防冲击火花、耐高温、防滑等特殊功能,相比于其它地坪材料,更能满足现代工业生产对地坪的不同要求。正是基于这些特点,现代建筑,特别是现代工业车间,如食品加工、制药、机械电子、仪器仪表、化工、航空、汽车等行业,大量使用环氧地坪涂料。
石家庄空调移机公司价格 我国的地坪涂料产业始于20世纪90年代初期,随着我国经济的快速发杭州屋面防水汕头空调维修18813-418628展,尤其是现代医药、电子、食品等行业的高速增长,带动了地坪涂料的市场需求量。地坪涂料已成为我国近年来涂料行业中继建筑涂料、交通车辆涂料、家具木器涂料以及海洋防腐涂料后,发展快的涂料品种之一。
环氧地坪涂料主要有两大类:环氧地坪涂料和聚氨酯地坪涂料[1]。环氧地坪涂料具有硬度高、抗压强度高、耐磨性好、耐化学品性优良等优点,但质脆、易裂,耐候性差,通常应用于紫外线较弱的室内场所或作底漆使用,由于使用成本相对便宜,得到了广泛应用,约占整个地坪涂料市场的70%。聚氨酯地坪涂料尽管在硬度和强度方面稍逊于环氧地坪涂料,但其各项性能具有广泛的可调节性,具有更好的柔韧性、耐冲击性、耐磨性、耐有机酸性、良好的抗紫外线性及耐化学腐蚀性等,行人行走时脚感舒适,缓解疲劳,并可隔音减噪,而且具有优异的户外耐候性,比环氧地坪涂料的应用范围更广。由于其使用成本较高,用量约占整个地坪涂料市场的25%。
随着全民健身理念日益深入民心,大到每个城市,小到每个社区或单位,都将会建造更多类别的体育场馆和场地,为健身和比赛提供便利,这些场地无论是耐候性的需要,还是人体舒适度的需要,聚氨酯地坪涂料都是地坪涂装面层的理想选择,相信聚氨酯地坪涂料的使用比例会不断提高。
目前我国地坪涂料80%以上为溶剂型涂料,其余的主要为无溶剂环氧涂料和聚脲喷涂体,水性地坪涂料所占比例很小。溶剂型地坪涂料中含有较多的有机溶剂,这些有机溶剂在涂料的生产和施工期间排入大气,污染环境,同时危害人类健康;此外溶剂型聚氨酯地坪涂料中还含有游离的异氰酸酯单体,在施工过程中,会严重影响人体健康和生活环境。而无溶剂环氧地坪涂料中含有少量的活性稀释剂,常用的活性稀释剂为丁基环氧丙基醚(有一定毒性),成本较高且仍含有一定量的挥发性有机溶剂。溶剂型地坪涂料在实际施工中还存在许多难以克服的弊病,如起泡、鼓泡、脱落、附着不良等,会受到环境温湿度、基层湿度,以及基面的其它问题的影响,特别是对基材的干燥程度要求很高,而实际施工时很难满足要求。
水性地坪涂料对基材的干燥程度要求低,施工工具可用水直接清洗,涂料的配制和施工操作安全方便,而且涂料不燃、不爆、安全,贮存和运输方便,避免了溶剂型涂料因储存运输和使用不当而引起的爆炸和火灾事故。近几年,随着国际原油价格的飞速增长和居高不下,有机溶剂等基本化工原料的价格普遍上扬,我国是一个石油资源紧张的国家,同时又是一个石油消费大国,节省资源已成为我国今后一项长期而又紧迫的战略任务。地坪涂料的水性化已成为必然趋势。

Floor coating has no juncture, whole decorate good, smooth surface, easy to clean, and excellent physical and mechanical properties and chemical resistance, moderate price, easy construction, easy maintenance, and many other features. Floor coating, moreover, can also according to special requirements, give the floor anti-static, special functions such as impact spark, high temperature resistant, prevent slippery, compared to other floor material, more can meet the different requirements of modern industrial production to the floor. Based on these characteristics, modern buildings, especially the modern industrial workshop, such as food processing, pharmacy, machinery and electronics, instrumentation, chemical, aerospace, automotive and other industries, and extensive use of floor coating.
The floor coating industry in China began in the early 1990 s, with the rapid development of economy in our country, especially in modern medicine, electronics, food industry such as high speed growth, driving the demand for the floor coating. Floor coating has become China's coating industry in recent years, relay architectural coatings, traffic paint, furniture wood coatings and Marine anticorrosive coatings, one of the fastest growing varieties of paint.
Floor coating mainly include two categories: epoxy floor coating and polyurethane floor coating [1]. Epoxy floor coating has high hardness, high compressive strength, good abrasion resistance, chemical resistance character is good wait for an advantage, but qualitative fragile, easy to crack, the weather is bad, often applied to indoor Spaces or weak uv primer is used, due to the use of relatively cheap cost, has been widely applied, accounts for about 70% of the whole floor coating market. Polyurethane floor coating although slightly behind in terms of hardness and strength of epoxy floor coating, but its various performance with a wide range of regulatory, have better flexibility, impact resistance, abrasion resistance, resistance to organic acid, uv linear and good resistance to chemical corrosion, etc., the pedestrian walking the foot feels comfortable, relieve fatigue, and can sound insulation, and excellent outdoor weatherability, application is wider than that of the epoxy floor coating. Due to the use of high cost, consumption accounts for about 25% of the whole floor coating market.
As the national fitness concept to sink to each city, small to each community or unit, which will build more categories of sports venues and venues, provide convenience for the fitness and competition, the field whether it is the need of weatherability, or the need of the human body comfort, pu floor coating is floor coating surface of the ideal choice, believe that the use of the pu floor coating proportion will continue to improve.
At present, more than 80% of the floor coating for solvent-based coating, the rest are mainly solvent-free epoxy coating and spray polyurea, water-borne floor coating proportion is very small. Conventional solvent-based coatings contained more organic solvent, these organic solvent in the production of paint and the atmosphere during construction, environmental pollution and harm to human health at the same time; In addition to all this solvent polyurethane floor coating contains free isocyanate monomer, in the process of construction, will seriously affect human health and living environment. And solventless epoxy floor coating containing a small amount of reactive diluent, commonly used active diluents for butyl epoxy propyl ether () has a certain toxicity, high cost and still contain a certain amount of volatile organic solvents. Conventional solvent-based coating in actual construction also has many difficult to overcome the disadvantages, such as blister, bubbling, fall off, and poor adhesion, etc., will be affected by environmental temperature and humidity, the humidity at the grass-roots level, and the influence of the other base surface, especially for dry degree requirements of the base material is very high, and the actual construction is difficult to meet the requirements.
Water-borne floor coating for dry degree requirements of the base material is low, construction tool can directly with water cleaning, coating preparation and construction of safe and convenient operation, and the coating is not burning, not burst, security, storage and transportation is convenient, to avoid the solvent coating caused by improper storage transportation and use of the explosion and fire accident. In recent years, with the rapid growth and high international crude oil prices, the price of basic chemical raw materials such as organic solvent generally rise, China is a country of petroleum resources nervous, and an oil consumption, save resources has become a long-term and urgent strategic task in the future. Floor coating of ability in swimming has become an inevitable trend.
