Abstract

The invention relates to a high-thermal-resistant self heat-preservation building block of an energy-saving building and a preparation process of the high-thermal-resistant self heat-preservation building block and relates to the technical field of building materials. The building block comprises the following components in parts by mass: 50-70 parts of cement, 35-45 parts of coal ash, 10-15 partsof macadam, 3-6 parts of polyphenyl granules, 2-5 parts of expanded perlite, 5-8 parts of rock wool, 6-10 parts of straw fiber, 2-4 parts of a water reduction agent and 10-15 parts of water, whereina preparation method of the straw fiber comprises the following steps: 1) performing washing dust collection on straw, and performing drying treatment; 2) after the straw is dried, shearing the strawto a length of 3-5mm; 3) soaking the sheared straw into a 10% sodium hydroxide solution, stirring the straw for 5-8 hours, and allowing the straw to stand for 10-12 hours; and 4) performing secondarydrying treatment on the straw treaded in the step 3), so as to obtain the straw fiber. The building block provided by the invention not only has a self heat-preservation property, but also has good compression resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an energy-saving building high thermal resistance self-insulation block and a preparation process thereof. Background technique [0002] With the progress of the society and the development of the economy, people's demand for energy continues to increase. At the same time, the deterioration of the environment has become more and more severe. Energy conservation and emission reduction have become a hot issue. Since energy conservation in buildings is currently the most direct and effective, It is also the most potential way to save energy. [0003] At present, most buildings in severe cold regions in my country adopt the form of external wall insulation. The service life of external wall insulation materials is generally about 25 years, which is far lower than the service life of the building itself. As a result, external wall insulation systems generally need to be rei...
