Abstract

The invention belongs to the field of building materials and in particular relates to a lightweight, thermal-insulation and high-strength green environment-friendly building board and a preparation method thereof. The environment-friendly building board comprises the following components in parts by weight: 5-10 parts of cement, 3-12 parts of coal gangue, 4-15 parts of coal ash, 2-8 parts of paraffin, 7-13 parts of urea, 4-8 parts of sulfomethylated phenolic resin, 6-14 parts of glass fiber, 8-15 parts of bentonite, 3-9 parts of methyl cellulose, 1-5 parts of mullite, 2-5 parts of medical stone, 2-5 parts of zeolite, 1-6 parts of sulfonylmethyl lignite, 4-15 parts of hydroxyethyl cellulose, and 0.5-1.5 parts of a foaming agent. The environment-friendly building board disclosed by the invention has the advantages of lightweight, excellent thermal-insulation, fire-proof and high-strength performances, which are much higher than the requirements of national and industry standards.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a light-weight, heat-preserving and high-strength environment-friendly building board and a preparation method thereof. Background technique [0002] With the rapid development of social economy, more and more buildings have sprung up, showing high-level requirements for "building height, building form and building quality". Among them, building insulation is a measure to reduce the indoor heat dissipation of buildings to the outside. It plays an important role in creating a suitable indoor thermal environment and saving energy. It is also an important requirement and guarantee for building quality. [0003] According to the different construction locations, building environmental protection measures are mainly divided into two methods: the external structure of the building and the internal wall of the building. Among them, building insulation from the peripheral c...
