Problems solved by technology

Although the stone industry has developed rapidly in recent years and has made great contributions to the local economy, there are still many problems, such as mountain damage, environmental pollution, waste pollution, etc., especially the pollution of stone processing waste. Disposal of these waste rocks and debris has become an urgent problem to be solved at present. Grinding waste rocks and using them as building materials is also one of the processing methods. With the improvement of construction quality requirements, walls are waterproof and wet base Problems such as waterproofing are becoming more and more prominent, and Yijiao is an effective means to solve this problem. Therefore, it is of great practical and environmental significance to develop how to apply waste rocks and debris to the production of Yijiao

preparation example Construction

[0019] The preparation method of stone powder waste regenerated beneficial clay comprises the following steps:

[0020] A. Separately crush waste stone powder and undried sea sand through a pulverizer;

[0021] B, drying the pulverized powder in step A through a gas dryer;

[0022] C. The powder dried in step B is separated by mesh size through a vibrating sieve, and the sieved powder is lifted to the raw material warehouse for storage by the hoist, and the unsifted powder is sent back to the pulverizer to continue pulverization;

[0023] D. Put the raw materials in the raw material warehouse into the mixer according to a certain proportion, and add a certain amount of redispersible latex powder, hydroxypropyl methylcellulose and hydrophobic agent. ;

[0024] E. Stir the mixture in step D evenly for a certain period of time, and finally put it into the finished product leveling bin, and pack it through a valve port packaging machine to obtain the regenerated benefit cement f...

Abstract

The invention discloses stone powder waste material regeneration easy plaster and a preparation method thereof. The stone powder waste material regeneration easy plaster is prepared from the following ingredients: 55 percent to 65 percent of waste stone powder, 20 percent to 30 percent of not-dried sea sand, 10 percent to 18 percent of cement, 1 percent to 3 percent of redispersible latex powder, 0.2 percent to 0.3 percent of hydroxypropyl methyl cellulose and 0.2 percent to 0.4 percent of hydrophobing agents. The stone powder waste material regeneration easy plaster is prepared by extracting stone powder waste materials and performing drying and recycling; the effects of environment protection and no pollution are achieved; the advantages of high bonding strength, high anti-permeability force, good water resistant performance, heat resistance, freeze thawing resistance and ageing resistance are realized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a kind of stone powder waste regenerated beneficial clay and a preparation method thereof. Background technique [0002] At present, the stone industry has developed into a comprehensive and diversified industry integrating granite, marble, artificial stone, stone carving, garden stone, cultural stone, stone machinery, abrasive tools, etc. Although the stone industry has developed rapidly in recent years and has made great contributions to the local economy, there are still many problems, such as mountain damage, environmental pollution, waste pollution, etc., especially the pollution of stone processing waste. Disposal of these waste rocks and debris has become an urgent problem to be solved at present. Grinding waste rocks and using them as building materials is also one of the processing methods. With the improvement of construction quality requirements, walls are w...
