    环氧地坪密封固化剂有哪些优势呢?

    一开始并没有环氧地坪密封固化剂这个名词,直到上世纪中期的时候,欧美很多工厂车间突然兴起了一种洁净的车间环氧地坪,这类环氧地坪相对比普通地坪来说,优点很明显,干净,容易清洗。而且耐磨,使用的时间长。它主要使用的是整体聚合物面层,后来就称它为环氧地坪。一直到今天,环氧地坪密封固化剂被广泛的应用于建筑材料中。

    There was no epoxy floor sealant at first. Until the middle of last century, many factories and workshops in Europe and America suddenly sprang up a kind of clean floor. Compared with ordinary floor, this kind of floor has obvious advantages, clean and easy to clean. And wear-resistant, long-term use. It mainly uses a monolithic polymer surface layer, later known as the epoxy floor. Up to now, epoxy floor sealant is widely used in building materials. 环氧地坪密封固化剂有哪些优势呢?

    What are the advantages of epoxy floor sealant curing agent?

    1、优良的附着力:环氧地坪涂料具有许多羟基及醚键,所以能与底材料吸附。而且环氧树脂固化时体积收缩率低(仅2%左右),故漆膜对金属(钢,铝),陶瓷,玻璃,混凝土,木材等极性底材均有优良的附着力。

    1. Excellent adhesion: Epoxy floor coating has many hydroxyl and ether bonds, so it can adsorb with the base material. Moreover, the volume shrinkage rate of epoxy resin curing is low (only about 2%), so the film has excellent adhesion to metal (steel, aluminum), ceramics, glass, concrete, wood and other polar substrates.

    2、抗化学品性能优良:环氧树脂中仅有烃基及醚键,没有酯键,所以耐碱性尤其突出,一般的油性或醇酸防锈底漆。在腐蚀时阴极部位呈碱性,会被皂化破坏。环氧地坪涂料耐碱而且附着力好,故可大量用作防腐蚀底漆。又因环氧地坏涂料固化后呈三维网状结构,又能耐油类的浸渍,也可大量用于油槽,油轮,飞机的整体油箱内壁衬里等的防腐。

    2. Good chemical resistance: epoxy resin has only alkyl and ether bonds, no ester bonds, so alkali resistance is particularly prominent, general oil or alkyd rust-proof primer. When corroded, the cathode is alkaline and will be destroyed by saponification. Epoxy floor coatings are alkali-resistant and have good adhesion, so they can be widely used as anticorrosive primers. Because of the three-dimensional network structure of epoxy floor coating after curing, it can also resist oil impregnation, and can also be widely used for anti-corrosion of tank, oil tanker, integral fuel tank lining of aircraft, etc.

    3、韧性好:与热固性酚醛树脂涂料相比较,环氧地坪涂料含芳环而坚硬,有醚键便于分子链的旋转,具有一定的韧性,而不像酚醛树脂很脆(因其交联间距比环氧树脂短)。环氧树脂交联间距长,便于内旋转,环氧树脂的分子量越大则交联间距越大。

    3. Good toughness: Compared with thermosetting phenolic resin coatings, epoxy floor coatings contain aromatic rings and are hard, with ether bonds to facilitate the rotation of molecular chains, and have certain toughness, unlike phenolic resin, which is brittle (because its crosslinking spacing is shorter than epoxy resin). The longer the crosslinking distance of epoxy resin is, the easier the internal rotation is. The larger the molecular weight of epoxy resin, the larger the crosslinking distance is.

    4、环氧树脂对湿面有一定的润湿力,尤其在使用聚酰胺树脂作固化剂时,可制成水下施工涂料,能排挤物体表面的水而涂布,可用于水下结构的抢修和水下结构的防腐蚀施工。

    4. Epoxy resin has a certain wetting force on wet surface. Especially when polyamide resin is used as curing agent, it can be made into underwater construction coatings, which can squeeze out the water on the surface of objects, and can be used for emergency repair of underwater structures and anti-corrosion construction of underwater structures.

    5、环氧树脂本身的分子不高,能与各种固化剂配合制造无溶剂,高固体分粉末涂料及水性涂料,符合环保要求,并能获得厚膜涂层。

    5. Epoxy resin has low molecular weight. It can cooperate with various curing agents to produce solvent-free, high solid powder coatings and water-borne coatings. It meets the requirements of environmental protection and can obtain thick film coatings.
