環氧地坪漆主要由環氧樹脂和固化劑組成，是一種高價值、高質量、高要求的產品，具有優良的耐磨性、耐沖壓性、耐洗刷性等物理特征，在使用時不易產生裂紋且易沖洗、易維修保養。環氧樹脂具有優良的電絕緣性質，可用于澆注密封，浸漬漆。無錫固化劑地坪具有很多優點，但也存在不足這處，其光老化性差。環氧樹脂中含有芳香醚鍵，漆膜經日光(紫外線)照射后易降解斷鏈，所以戶外耐候性較差。故通常的雙酚A系環氧樹脂不耐戶外日曬，漆膜易失光變色，然后粉化，不宜用作戶外的面漆。相關閱讀《室外停車場能做環氧地坪漆嗎》。

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、環氧樹脂

I. Epoxy Resin

環氧地坪漆具有良好的堅韌性，硬度，耐磨性能，主要來源于環氧地坪漆中一種材料：環氧樹脂。

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

環氧樹脂中僅有烴基及醚鍵，沒有酯鍵，所以耐堿性尤其突出，一般的油性或醇酸防銹底漆。在腐蝕時陰極部位呈堿性，會被皂化破壞。環氧地坪漆材料耐堿而且附著力好，故可大量用作防腐蝕底漆。又因環氧地壞涂料固化后呈三維網狀結構，又能耐油類的浸漬，也可大量用于油槽，油輪，飛機的整體油箱內壁襯里等的防腐。

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.

與熱固性酚醛樹脂涂料相比較，環氧地坪漆材料含芳環而堅硬，有醚鍵便于分子鏈的旋轉，具有一定的韌性，而不像酚醛樹脂很脆(因其交聯間距比環氧樹脂短)。環氧樹脂交聯間距長，便于內旋轉，環氧樹脂的分子量越大則交聯間距越大。

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.

環氧樹脂對濕面有一定的潤濕力，尤其在使用聚酰胺樹脂作固化劑時，可制成水下施工涂料，能排擠物體表面的水而涂布，可用于水下結構的搶修和水下結構的防腐蝕施工。

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.

環氧樹脂本身的分子不高，能與各種固化劑配合制造無溶劑，高固體分粉末涂料及水性環氧地坪涂料，符合環保要求，并能獲得厚膜涂層。

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.

環氧樹脂含有環氧基及羥基兩種活潑基團，能與多元胺，聚酰胺樹脂，酚醛樹脂，氨基樹脂，多異氰酸酯等配合，制成多種涂料，既可常溫干燥，也可高溫烘烤，以滿足不同的施工要求。

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、固化劑

2. Curing agent

幾種常用的商品固化劑：593固化劑、T31固化劑、651固化劑、810固化劑、酮亞胺固化劑、NX-2040固化劑。

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.

各種固化劑對環氧地坪漆性能的影響主要體現在涂膜硬度，凝膠時間和涂膜干燥時間。好的固化劑會使環氧地坪漆具有一定的硬度，且具有較長的操作時間，較快的干燥時間，這樣方便配置一桶地坪漆后能在操作時間內施工完成，而后可以很快的干燥，馬上施工第2道工序(一般凝膠時間在30分鐘以內，涂膜表干在4小時以內)。

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).

固化劑的種類主要分為胺類和樹脂類固化劑。其中胺類固化劑中，脂環胺及其加成物色淺、流平性好、光澤高、不泛白、不需誘導期，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.

在胺類固化劑中，脂環胺及其加成物色淺、流平性好、光澤高、不泛白、不需誘導期，但其玻璃化溫度較高，柔韌性較差，主要用作無溶劑環氧地坪涂料的固化劑，使用時尚需同時加入聚硫橡膠、長鏈烷基縮水甘油醚、彈性聚氨酯等增韌劑進行增韌處理。

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.
