Composite gypsum material for construction

Abstract

The invention discloses composite gypsum for construction, which is compounded by gypsum generated by at least two different raw materials, and contains modifying gypsum and modified gypsum which are mixed in weight proportion. The modifying gypsum is desulphurized gypsum; and the modified gypsum is phosphogypsum or fluorgypsum or natural gypsum, and is mixed with the modifying gypsum in a proportion that the desulphurized gypsum accounts for 10 to 50 percent of the total weight of the modifying gypsum and the modified gypsum. The modifying gypsum is the phosphogypsum or the fluorgypsum or the natural gypsum; and the modified gypsum is the desulphurized gypsum, and is mixed with the modifying gypsum in a proportion that the desulphurized gypsum accounts for 50 to 80 percent of the total weight of the modifying gypsum and the modified gypsum. Fiber materials are doped in the composite gypsum, and comprise glass fiber, bamboo reinforcement, fibrous plaster and sawmilling. The composite gypsum with excellent performance is obtained after mixing modification by using the gypsum generated by different raw materials, and has the advantages of convenient production and operation, simple manufacture process, short construction period and low cost.

Description

technical field [0001] The invention relates to a building material, in particular to a composite gypsum material for building. Background technique [0002] With the progress of society and the continuous development of economy, environmental protection is becoming more and more important. On the one hand, emission reduction has become a common goal of the world and a national policy of our country. On the other hand, protecting vegetation and resources has become a major measure of our country. In this context, the traditional building materials "Qin bricks and Han tiles" that have been passed down for thousands of years have been banned by the state and become history. As a pillar industry in my country's real estate industry, how to solve the problem of large-scale and wide-ranging building materials has been put on the agenda. From the central government to local governments, provincial and municipal governments have set up "wall reform offices" to be responsible for th...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a kind of composite gypsum for construction. The comprehensive performance of the composite gypsum is better than that of single gypsum. It can be used to make building partition walls or make filling molds for reinforced concrete composite floors, and its performance is excellent. It is better than using a single gypsum, and can adjust different compound formulas according to specific performance requirements to meet a variety of complex requirements, and the production method is simple, the construction period is short, and the cost is low, so as to overcome the shortcomings of the existing single gypsum material
