    环氧地坪漆材料主要成分包括那些东西

    2019-04-26 09:20:15 无锡盛发地坪科技有限公司 阅读

    环氧地坪漆主要由环氧树脂和固化剂组成,是一种高价值、高质量、高要求的产品,具有优良的耐磨性、耐冲压性、耐洗刷性等物理特征,在使用时不易产生裂纹且易冲洗、易维修保养。环氧树脂具有优良的电绝缘性质,可用于浇注密封,浸渍漆。环氧树脂具有很多优点,但也存在不足这处,其光老化性差。环氧树脂中含有芳香醚键,漆膜经日光(紫外线)照射后易降解断链,所以户外耐候性较差。故通常的双酚A系环氧树脂不耐户外日晒,漆膜易失光变色,然后粉化,不宜用作户外的面漆。相关阅读《室外停车场能做环氧地坪漆吗》。

    Epoxy floor paint is mainly composed of epoxy resin and curing agent. It is a product of high value, high quality and high requirement. It has excellent physical characteristics such as wear resistance, stamping resistance, washing resistance and so on. It is not easy to produce cracks in use and easy to wash and maintain. Epoxy resin has excellent electrical insulation properties and can be used for casting sealing and impregnating paint. Epoxy resin has many advantages, but there are also shortcomings, its light aging is poor. Epoxy resin contains aromatic ether bonds. The film is easy to degrade and break chains after being irradiated by sunlight (ultraviolet), so its outdoor weather resistance is poor. Therefore, the usual bisphenol A epoxy resin is not resistant to outdoor sunlight, and the paint film is liable to lose light and discoloration, and then powdered, so it is not suitable for outdoor topcoat.

    一、环氧树脂

    I. Epoxy Resin

    环氧地坪漆具有良好的坚韧性,硬度,耐磨性能,主要来源于环氧地坪漆中一种材料:环氧树脂。

    Epoxy floor paint has good toughness, hardness and wear resistance. It mainly comes from epoxy resin, a kind of material in floor paint.

    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。环氧地坪漆材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。

    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 paint material is alkali-resistant and has good adhesion, so it can be widely used as anticorrosive primer. 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.

    与热固性酚醛树脂涂料相比较,环氧地坪漆材料含芳环而坚硬,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。

    Compared with thermosetting phenolic resin coatings, epoxy floor paint materials 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 very brittle (because its crosslinking spacing is shorter than that of 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.

    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。

    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.

    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环氧地坪涂料,符合环保要求,并能获得厚膜涂层。

    Epoxy resin has low molecular weight and can be used with various curing agents to produce solvent-free, high solid powder coatings and waterborne epoxy floor coatings, which meet the requirements of environmental protection and can obtain thick film coatings.

    环氧树脂含有环氧基及羟基两种活泼基团,能与多元胺,聚酰胺树脂,酚醛树脂,氨基树脂,多异氰酸酯等配合,制成多种涂料,既可常温干燥,也可高温烘烤,以满足不同的施工要求。

    Epoxy resin contains two kinds of active groups, epoxy group and hydroxyl group. It can cooperate with polyamines, polyamide resin, phenolic resin, amino resin, polyisocyanate and so on to make a variety of coatings, which can be dried at room temperature or baked at high temperature to meet different construction requirements.

    二、固化剂

    2. Curing agent

    几种常用的商品固化剂:593固化剂、T31固化剂、651固化剂、810固化剂、酮亚胺固化剂、NX-2040固化剂。

    Several commonly used commercial curing agents: 593 curing agent, T31 curing agent, 651 curing agent, 810 curing agent, ketoimide curing agent, NX-2040 curing agent.

    各种固化剂对环氧地坪漆性能的影响主要体现在涂膜硬度,凝胶时间和涂膜干燥时间。好的固化剂会使环氧地坪漆具有一定的硬度,且具有较长的操作时间,较快的干燥时间,这样方便配置一桶地坪漆后能在操作时间内施工完成,而后可以很快的干燥,马上施工第2道工序(一般凝胶时间在30分钟以内,涂膜表干在4小时以内)。

    The effects of various curing agents on the performance of epoxy floor paint are mainly reflected in film hardness, gel time and film drying time. Good curing agent will make the floor paint with certain hardness, and has a longer operation time and a faster drying time, so that a barrel of floor paint can be easily configured to complete the construction in operation time. Then it can be quickly dried and immediately build second processes (generally gel time is less than 30 minutes, and the coating is dry within 4 hours).

    固化剂的种类主要分为胺类和树脂类固化剂。其中胺类固化剂中,脂环胺及其加成物色浅、流平性好、光泽高、不泛白、不需诱导期,但其玻璃化

    The types of curing agents are mainly classified into amine and resin curing agents. Among the amine curing agents, alicyclic amines and their additives have light colour, good leveling, high gloss, no whitening and no induction period, but they are vitrified.

    在胺类固化剂中,脂环胺及其加成物色浅、流平性好、光泽高、不泛白、不需诱导期,但其玻璃化温度较高,柔韧性较差,主要用作无溶剂环氧地坪涂料的固化剂,使用时尚需同时加入聚硫橡胶、长链烷基缩水甘油醚、弹性聚氨酯等增韧剂进行增韧处理。

    Among amine curing agents, alicyclic amines and their additives have light colour, good leveling, high gloss, no whitening and no induction period, but their glass transition temperature is high and their flexibility is poor. They are mainly used as curing agents for solvent-free epoxy floor coatings. Polysulfur rubber, long chain alkyl glycidyl ether, elastic polyurethane and other toughening agents need to be added to toughen them.
