廠傢揭示影響环氧防靜電地坪的要素有哪些

环氧防靜電地坪對於防靜印花地坪電的效果要求很高，所以對於影響环氧地坪的因素环氧地坪要求也很高，影響环氧防靜電地坪的要素有哪些呢？我們一起看看：要素一、導電介質的選用:如碳系導電物質、金屬導電介質、金屬氧化物復合導電粉等，不同的導電介質其導電效果不同：
Epoxy anti-static floor for anti-static effect requirements are very high, so the factors affecting the epoxy floor is also high, what are the factors affecting the epoxy anti-static floor? Let's look at it together: First, the selection of conductive media: such as carbon-based conductive materials, metal conductive media, metal oxide composite conductive powder, the conductive effect of different conductive media is different:
（1）碳系導電物質主要是石墨和碳黑，是防靜電塗料中比較常用的導電物質，其導電性較好，價格便宜，但由於其比表面積大，吸油量高，在制作無溶劑抗靜電塗料時添加量稍大時塗料的粘度上升，自流平性變差，因此隻能作為輔助添加導電物質，但可用於制作溶劑型抗靜電塗料及導電膩子，顏色隻能是黑色或深色。
(1) Carbon-based conductive materials are mainly graphite and carbon black, which are commonly used in antistatic coatings. They have good conductivity and low price. However, due to their large specific surface area and high oil absorption, the viscosity of the coatings increases and the self-leveling of the coatings becomes worse when the amount of the additives is slightly larger in the preparation of solvent-free antistatic coatings. To assist in the addition of conductive materials, but can be used to make solvent-based antistatic coatings and conductive putty, the color can only be black or dark.
（2）金屬導電介質：導電性能好，但塗料顏色受金屬粉體色限制，該類粉末比重大，易沉降，在漆膜中易下沉，與空氣接觸易氧化（而惰性金屬價貴），這都易導致塗膜導電性能不穩定。
(2) Metal conductive medium: good conductivity, but the color of the coating is limited by the color of metal powder, this kind of powder is heavy, easy to settle, easy to sink in the film, easy to oxidize in contact with the air (but the inert metal is expensive), which easily lead to unstable conductivity of the film.
（3）金屬氧化物復合導電粉：顏色淺，可制作各色抗靜電塗料，導電性能基本能夠滿足要求，吸油量適中，價格較高。
(3) Metal oxide composite conductive powder: light color, can be made of various colors of antistatic coatings, conductivity can basically meet the requirements, moderate oil absorption, higher prices.
要素二、成膜基料的選用：無溶劑环氧自流平抗靜電环氧地坪塗料應選用低分子量的环氧樹脂配以活性稀釋劑及非活性稀釋劑與固化劑反應成膜；溶劑型环氧抗靜電环氧地坪塗料可選用中等分子量的环氧樹脂與胺類固化劑作為成膜物質。
Element 2. Selection of film-forming base materials: Low molecular weight epoxy resin, reactive diluent and non-reactive diluent should be used in solvent-free epoxy self-leveling antistatic floor coatings; medium molecular weight epoxy resin and amine curing agent can be used as film-forming materials in solvent-based epoxy antistatic floor coatings.
要素三、助劑的選用:由於導電介質與基料及著色顏料的相容性不佳，所以須選用合適的潤濕分散劑以解決浮色發花現象，同時，對顏料的選用和分散應加以重視。由於導電粉沉降易導致漆膜表面抗靜電性能下降，特別是自流平產品，塗膜厚，表幹時間長，沉降更易發生。因而采用一些助劑避免此種現象的發生是必要的，同時需防止塗料流平性受助劑影響而下降。另外，還需選用流平劑、消泡劑等助劑。
Element 3. Selection of auxiliaries: Due to the poor compatibility of conductive media with the substrate and coloring pigments, it is necessary to select a suitable wetting and dispersing agent to solve the problem of floatation, and at the same time, attention should be paid to the selection and dispersion of pigments. The antistatic property of the film surface is easily degraded due to the deposition of conductive powder. Especially for self-leveling products, the film is thick, the surface drying time is long, and the deposition is easy to occur. Therefore, it is necessary to use some additives to avoid this phenomenon. At the same time, it is necessary to prevent the leveling of coatings from being affected by additives. In addition, some additives such as leveling agent and defoamer are also needed.
要素四、固化劑的選用:對於自流平抗靜電地坪塗料，一般選用改性脂肪胺類固化劑，並根據施工环境的溫度選用不同凝膠時間的產品，既要考慮塗料要有適當的使用期以便於施工操作，又要考慮幹燥時間不能太長，避免導電粉沉降現象加重。
Factor four, curing agent selection: for self leveling anti-static floor coatings, generally modified aliphatic amine curing agents, and according to the construction environment temperature selection of products with different gel time, we should consider that the paint should have an appropriate period of use to facilitate construction operation, and consider that the drying time can not be too long, to avoid conductive powder. The settlement phenomenon is aggravated.
