Abstract

The invention discloses a grade-A fireproof efficient homogeneous thermal self-insulation block belonging to the technical field of building materials. The thermal self-insulation block with relatively high strength, relatively low heat conductivity coefficient as well as relatively strong water resistance and weather resistance is formed through reasonably designing the ratio of materials such as ceramsite, fragmented ceramsite particles, a perlite modifier, perlite, perlite powder, cement, coal ash, silica fume, a water reducing agent, a waterproof agent, a power shrinkage reducing agent and water, so that the national requirement for saving energy of a civil building by 75% at present and in future can be met; in addition, all the materials are inorganic materials, and the fireproof performance is up to the grade A, so that fire hazards of a thermal insulation filler wall of an exterior wall are thoroughly eliminated, meanwhile, the aim of saving energy by 75% is achieved, and the national requirements for the fireproof grade of an external thermal insulation product of the exterior wall and a higher energy-saving standard are met; and the production process is simple, and the grade-A fireproof efficient homogeneous thermal self-insulation block has a relatively high popularization value and a very wide market prospect.

Description

technical field [0001] The invention relates to a high-efficiency homogeneous self-insulation block for class A fire prevention, which belongs to the technical field of building materials. Background technique [0002] With the gradual improvement of the country's energy-saving standards, the requirements for energy-saving and thermal insulation of external walls are getting higher and higher. Now Beijing and other cities have implemented the 75% energy-saving standard, and Shandong and other provinces and cities have also implemented it one after another. This is the general trend. At present, the insulation bricks on the market are mainly hollow fired mud bricks made of clay or unfired cement bricks whose formula raw materials are mainly made of cement, sand, and limestone particles. Since the middle part of this type of hollow wall brick is hollow, it is easy to loosen when nailed into the wall nails to hang heavy objects. For homogeneous blocks, due to the limitation of...
