Abstract

The invention specifically relates to a lightweight, heat-preserving, high-strength and environment-friendly building board and a preparation method thereof, belonging to the field of building materials. The environment-friendly building board is prepared from the following components by weight: 5 to 10 parts of cement, 4 to 15 parts of gangue, 2 to 8 parts of paraffin, 7 to 13 parts of urea, 4 to 8 parts of sulfomethyl phenol formaldehyde resin, 6 to 14 parts of a glass fiber, 8 to 15 parts of bentonite, 3 to 9 parts of methyl cellulose, 1 to 5 parts of mullite, 2 to 5 parts of Chinese medical stone, 2 to 5 parts of zeolite, 1 to 6 parts of sulfomethyl lignite, 4 to 15 parts of hydroxyethyl cellulose and 0.5 to 1.5 parts of a foaming agent. The board provided by the invention has good performances like lightweight, heat preservation, fire resistance and high strength, and the performance index of the board is much higher than national and industrial standard requests in China.

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...
