盧灣區環氧地坪漆分析地坪涂料現狀
環氧地坪涂料具有無接縫、整體裝飾性好、表面光潔、易于清潔，以及物理機械性能和耐化學品性能優良，價格適中，施工簡便，維修方便等諸多特點。另外，地坪涂料還可根據特殊需求，賦予地坪防靜電、防沖擊火花、耐高溫、防滑等特殊功能，相比于其它地坪材料，更能滿足現代工業生產對地坪的不同要求。正是基于這些特點，現代建筑，特別是現代工業車間，如食品加工、制藥、機械電子、儀器儀表、化工、航空、汽車等行業，大量使用環氧地坪涂料。
我國的地坪涂料產業始于20世紀90年代初期，隨著我國經濟的快速發杭州屋面防水汕頭空調維修18813-418628展，尤其是現代醫藥、電子、食品等行業的高速增長，帶動了地坪涂料的市場需求量。地坪涂料已成為我國近年來涂料行業中繼建筑涂料、交通車輛涂料、家具木器涂料以及海洋防腐涂料后，發展快的涂料品種之一。
環氧地坪涂料主要有兩大類：環氧地坪涂料和聚氨酯地坪涂料［1］。環氧地坪涂料具有硬度高、抗壓強度高、耐磨性好、耐化學品性優良等優點，但質脆、易裂，耐候性差，通常應用于紫外線較弱的室內場所或作底漆使用，由于使用成本相對便宜，得到了廣泛應用，約占整個地坪涂料市場的70%。聚氨酯地坪涂料盡管在硬度和強度方面稍遜于環氧地坪涂料，但其各項性能具有廣泛的可調節性，具有更好的柔韌性、耐沖擊性、耐磨性、耐有機酸性、良好的抗紫外線性及耐化學腐蝕性等，行人行走時腳感舒適，緩解疲勞，并可隔音減噪，而且具有優異的戶外耐候性，比環氧地坪涂料的應用范圍更廣。由于其使用成本較高，用量約占整個地坪涂料市場的25%。
隨著全民健身理念日益深入民心，大到每個城市，小到每個社區或單位，都將會建造更多類別的體育場館和場地，為健身和比賽提供便利，這些場地無論是耐候性的需要，還是人體舒適度的需要，聚氨酯地坪涂料都是地坪涂裝面層的理想選擇，相信聚氨酯地坪涂料的使用比例會不斷提高。
目前我國地坪涂料80%以上為溶劑型涂料，其余的主要為無溶劑環氧涂料和聚脲噴涂體，水性地坪涂料所占比例很小。溶劑型地坪涂料中含有較多的有機溶劑，這些有機溶劑在涂料的生產和施工期間排入大氣，污染環境，同時危害人類健康；此外溶劑型聚氨酯地坪涂料中還含有游離的異氰酸酯單體，在施工過程中，會嚴重影響人體健康和生活環境。而無溶劑環氧地坪涂料中含有少量的活性稀釋劑，常用的活性稀釋劑為丁基環氧丙基醚（有一定毒性），成本較高且仍含有一定量的揮發性有機溶劑。溶劑型地坪涂料在實際施工中還存在許多難以克服的弊病，如起泡、鼓泡、脫落、附著不良等，會受到環境溫濕度、基層濕度，以及基面的其它問題的影響，特別是對基材的干燥程度要求很高，而實際施工時很難滿足要求。
水性地坪涂料對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，貯存和運輸方便，避免了溶劑型涂料因儲存運輸和使用不當而引起的爆炸和火災事故。近幾年，隨著國際原油價格的飛速增長和居高不下，有機溶劑等基本化工原料的價格普遍上揚，我國是一個石油資源緊張的國家，同時又是一個石油消費大國，節省資源已成為我國今后一項長期而又緊迫的戰略任務。地坪涂料的水性化已成為必然趨勢。

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.
