Description
技术领域technical field
本发明涉及建筑材料技术领域，尤其是一种保温阻燃建筑材料及其制备方法。The invention relates to the technical field of building materials, in particular to a thermal insulation and flame retardant building material and a preparation method thereof.
背景技术Background technique
中国目前的建筑设计施工中，有90％以上都采用了有机绝热材料作为外墙装饰的保温材料。由于其价格低廉，施工过程简易，从90年代起就受到了相关部门的推荐，但游记材料的致命的缺点就是易燃，近年来中国很多起特大火灾事故都是由于有机保温材料造成的。In China's current architectural design and construction, more than 90% have adopted organic thermal insulation materials as thermal insulation materials for exterior wall decoration. Due to its low price and simple construction process, it has been recommended by relevant departments since the 1990s. However, the fatal shortcoming of travel materials is that they are flammable. In recent years, many serious fire accidents in China have been caused by organic thermal insulation materials.
利用多孔、蜂窝状的轻质无机材料制备无机保温材料是另一条保温途径。无机保温材料具有原材料环保、不燃、耐候性能优异、不易老化的特性，既符合发展循环经济的要求，又符合节能减排的要求。这为无机保温隔热材料提供了极好的发展空间。但无机保温材料也存在不足，主要表现在导热系数较高，易吸水、保温效果差，材料存在脆性，易收缩开裂等。The use of porous, honeycomb light inorganic materials to prepare inorganic thermal insulation materials is another way of thermal insulation. Inorganic thermal insulation materials have the characteristics of environmentally friendly raw materials, non-combustibility, excellent weather resistance, and not easy to age. They not only meet the requirements of developing circular economy, but also meet the requirements of energy saving and emission reduction. This provides an excellent development space for inorganic thermal insulation materials. However, inorganic thermal insulation materials also have deficiencies, mainly in high thermal conductivity, easy water absorption, poor thermal insulation effect, brittleness of materials, and easy shrinkage and cracking.
申请号为201010597354.0中公开了一种建筑外墙保温阻燃带，其虽然在一定程度上提高了外墙保温系统的防火性能，但是该发明中采用的玻化微珠为轻骨料，在实际应用中，由于玻化微珠的闭孔特性，导致其与凝胶材料的结合力下降，施工中易脱落。The application number is 201010597354.0, which discloses a building exterior wall thermal insulation flame-retardant tape. Although it improves the fire performance of the external wall thermal insulation system to a certain extent, the vitrified microspheres used in this invention are lightweight aggregates. In application, due to the closed-cell characteristics of vitrified microbeads, the binding force between them and the gel material decreases, and they are easy to fall off during construction.
