A kind of wall adsorption and decontamination high adhesion environmental protection cement

Abstract

A wall adsorption and decontamination high-adhesion environmental protection cement relates to the technical field of cement preparation and comprises the following raw materials: 400-500 parts of silicate clinker, 300-400 parts of base material, 55-88 parts of silica fume, dihydrate 45-85 parts of gypsum, 25-40 parts of tackifier, 5-18 parts of modifier, and 4-8 parts of reinforcing agent. The beneficial effects of the present invention are as follows: use inorganic silicate clinker and ore with strong cation exchange and adsorption performance, soak in hydrochloric acid, and then bake at high temperature to increase the specific surface area of ​​particles, enhance the adsorption performance and improve the environmental protection of cement Mixed grinding with silicate boiled balls can also produce mechanical reaction, change the mineral activity of the system, increase the gelling particles in the hydrate, and improve the cement strength grade.

Description

technical field [0001] The invention relates to the technical field of cement preparation, in particular to a wall adsorption and decontamination high-adhesion environmental protection cement. Background technique [0002] At present, the base of the wall of the building is made of cement enamel. Since the cement has no bonding strength in the early stage, it is necessary to add cement admixtures. Most of the cement admixtures are organic compounds, which emit organic harmful gases during the cement hydrothermal conversion process. , Some admixtures are made of mixed rubber, containing harmful substances such as benzene, amines, and formaldehyde. In addition, the bricks and boards used in building walls in construction projects need to be plastered and bonded. In the early days, lime plaster mixed with cement was used as the wall-building adhesive. Due to the large amount of lime used, the cost is high and it is inconvenient to use. In recent years, the "mortar treasure" ma...

Problems solved by technology

At present, foam concrete wall insulation projects account for more than 70% of the market, but the cement used in foam concrete has not been modified, and the cement is prone to cracking during the hydrothermal process, and the adhesion performance is poor, because the cement has no adhesion at the initial stage , it is difficult to hang dust on the facade of the wall. During production, rubber powder is added to the cement. There are many types of rubber powder. Generally speaking, rubber powder is an organic compound and has emissions.

In the early stage of cement hydration, water molecules are discharged, forming micropores and poor sealing performance. The ethylene foam particles and fly ash in the material have strong water absorption. When it rains, water absorption increases the weight of the wall, reduces the insulation quality, and affects insulation materials. service life
