无机涂料是一种以无机材料为主要成膜物质的涂料，是全无机矿物涂料的简称，因性能优质，广泛用于建筑、绘画等日常生活领域。
无机涂料是由无机聚合物和经过分散活化的金属、金属氧化物纳米材料、稀土超微粉体组成的无机聚合物涂料，能与钢结构表面铁原子快速反应，生成具有物理、化学双重保护作用，通过化学键与基体牢固结合的无机聚合物防腐涂层，对环境无污染，使用寿命长，防腐性能达到国际先进水平，是符合环保要求的高科技换代产品。
有机涂料一直以自身良好的装饰性、价格的低廉以及品种多样性被消费者购买，但是由于其原材料取材于煤、石油、天然气等化工资源，很容易在生产过程中产生大量的有害物质，引起严重的环境污染问题，并且难以满足人们对安全、健康的需求。有机涂料涂饰在墙体表面与外墙形成涂膜，而空气与水分所产生的压力受温度的影响而在不透气的内外墙表面产生运动，不断作用于涂料的涂膜，一段时间后，将使墙面涂膜出现空鼓、起泡甚至掉皮脱落，因此无机涂料的应运而生符合这个时代环保家装的潮流。
那有机涂料和无机涂料在本质上有什么区别呢?
第一，无机涂料的基料材料往往直接取材于自然界，因而来源十分丰富。例如，硅溶胶，硅酸盐溶液等涂料基料，其主要原材料来源于石英质矿石，是自然界中极为丰富的材料。
第二，相对于一些有机涂料基料来说，无机涂料基料的生产及使用过程中对环境的污染小，产品多数是以水为分散介质，无环境和健康方面的不良影响。
第三，无机涂料的耐老化及某些物理化学性能是绝大多相同生产成本的有机涂料很难达到的，因此其具有较好的技术经济性能。
第四，无机涂料多数呈碱性，更适合于在同样显碱性的水泥和灰砂等基层上应用，而且可与这些基材中的石灰产生化学反应生成硅酸钙晶体，能够和基层形成一体，因而其附着力特别好。

Inorganic coating is a kind of coating with inorganic material as the main film-forming material, which is the abbreviation of all inorganic mineral coating. Because of its high performance, it is widely used in construction, painting and other fields of daily life.
Inorganic coating is an inorganic polymer coating composed of inorganic polymer, dispersed activated metal, metal oxide nano material and rare earth ultra-fine powder. It can react with iron atom on the surface of steel structure rapidly, and generate an inorganic polymer anticorrosive coating with physical and chemical double protection. It has no pollution to the environment and long service life through the solid combination of chemical bond and matrix, The anti-corrosion performance has reached the international advanced level, and it is a high-tech replacement product in line with environmental protection requirements.
Organic coatings have been purchased by consumers for their good decoration, low price and variety diversity. However, due to the raw materials from coal, oil, natural gas and other chemical resources, it is easy to produce a large number of harmful substances in the production process, causing serious environmental pollution problems, and difficult to meet people's demand for safety and health. The organic coating forms a film on the wall surface and the outer wall, while the pressure generated by air and water is affected by temperature and moves on the airtight inner and outer wall surface, constantly acting on the coating. After a period of time, the wall coating will appear hollowing, blistering or even peeling off, so the inorganic coating came into being in line with the trend of environmental protection home furnishings in this era.
What is the essential difference between organic coatings and inorganic coatings?
First, the base materials of inorganic coatings are often directly from the nature, so the source is very rich. For example, silica sol, silicate solution and other coating base materials, whose main raw materials come from quartz ore, are extremely rich in nature.
Second, compared with some organic coating materials, the production and use of inorganic coating materials have little environmental pollution, most of the products are water as the dispersion medium, without adverse environmental and health effects.
Third, the aging resistance and some physical and chemical properties of inorganic coatings are difficult to achieve for most organic coatings with the same production cost, so they have better technical and economic properties.
Fourth, most of the inorganic coatings are alkaline, which is more suitable for the application of the same alkaline cement and lime sand base, and can react with the lime in these base materials to generate calcium silicate crystal, which can form an integral part with the base, so its adhesion is particularly good.
