Description
技术领域technical field
本发明涉及阻燃涂料领域，尤其涉及一种膨胀型水性无机阻燃涂料及其制备方法。The invention relates to the field of flame-retardant coatings, in particular to an intumescent water-based inorganic flame-retardant coating and a preparation method thereof.
背景技术Background technique
阻燃涂料又称防火涂料，它不但具有普通涂料的装饰性，而且涂料本身还具有防火保护功能，自1837年第一个阻燃涂料配方问世，阻燃涂料经历了近两百年的发展。早期的阻燃涂料一般为非膨胀型阻燃涂料，其防火性能及涂膜的其它物理力学性能都很差，近年来，经过研发人员的不断努力，出现了防火性能优越的膨胀型阻燃涂料，但目前膨胀型阻燃涂料大多为有机体系，在环保法规日益完善，人们对环境污染及人身健康日益重视的今天，挥发性有机化合物(VOC)含量很高的溶剂型涂料的使用受到越来越严格的限制，环境友好型防火涂料成为各研究公司的主要开发对象。Flame-retardant coatings are also called fire-resistant coatings. They not only have the decorative properties of ordinary coatings, but also have the function of fire protection. Since the first formulation of flame-retardant coatings came out in 1837, flame-retardant coatings have experienced nearly two hundred years of development. The early flame retardant coatings are generally non-intumescent flame retardant coatings, and their fire resistance and other physical and mechanical properties of the coating film are very poor. In recent years, through the continuous efforts of researchers, intumescent flame retardant coatings with superior fire resistance have appeared , but most of the current intumescent flame retardant coatings are organic systems. Today, with the improvement of environmental protection regulations and people's increasing attention to environmental pollution and personal health, the use of solvent-based coatings with high volatile organic compound (VOC) content has become more and more popular. The stricter the restriction, the environment-friendly fireproof coating becomes the main development object of various research companies.
以水为介质制成的膨胀型水性无机阻燃涂料响应了低VOC甚至无VOC的环保涂料的发展方针，不仅适合市场发展，涂料行业的升级，更是响应了人们对“绿色涂料”的渴望。The intumescent water-based inorganic flame-retardant coating made of water responds to the development policy of low-VOC or even VOC-free environmentally friendly coatings. It is not only suitable for market development and the upgrading of the coatings industry, but also responds to people's desire for "green coatings" .
