Abstract

The invention relates to the technical field of building materials and particularly discloses a lightweight hollow partition wallboard, comprising the following components: component A including in percent by weight: 57-65% of solid residue and flyash, 13-18% of cement, 10-15% of mineral powder and 12-16% of fluorine gypsum; component B including a mixture of 45-55% by weight of anhydrous sodium sulfate and 45-55% by weight of aluminum potassium sulfate dodecahydrate; component C including dihydrate gypsum; the components A, B and C have a weight ratio of 1000:0.5-2:30-50. The lightweight hollow partition wallboard is low in carbon, environment-friendly, light in weight, short in forming time, low in toxic and side effect and good in service performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a lightweight hollow partition wall board. Background technique [0002] With the development of science and technology and the continuous improvement of living standards, the concept of sustainable development has been deeply rooted in the hearts of the people. Specifically in the field of building materials, building materials are required to be energy-saving, environmentally friendly, lightweight, and better in use, such as mechanical strength, fire resistance, Sound insulation, moisture-proof and waterproof performance, and easy construction. Based on this, traditional building materials represented by clay brick walls are gradually being replaced by new-type extruded panels, ordinary gypsum hollow slats, high-strength water-resistant gypsum-based ecological wallboards and other lightweight wallboards. get promoted. However, the above-mentioned lightweight wallboa...
