Embodiment 1

[0015] The preparation method of utilizing epoxy resin powder to produce low-temperature cement comprises the steps:

[0016] 1) Take epoxy resin powder, sludge and wood calcium as raw materials, mix the above three raw materials according to the weight ratio of 80:12:8, add water and stir evenly;

[0017] 2) the mixture obtained in the above step 1) is made into a material body with a particle size of 1-8mm for subsequent use;

[0018] 3) enter the drying kiln after solidifying the material body described in step 2), and cool it out of the kiln and put it into the warehouse after roasting at 600 degrees for 10 minutes;

[0019] 4) Mix the material obtained in step 3) with gypsum or silicate clinker, and put it into a ball mill to grind it into a fine powder with a particle size of less than 600 mesh, to obtain epoxy resin powder low-temperature cement.

[0020] The low-temperature cement prepared in this example has high cement strength, good concrete compatibility, good wea...

Abstract

The invention provides a preparation method for producing novel low-temperature cement by utilizing epoxy resin powder. The preparation method mainly comprises the steps of material preparation, burdening and forming, curing, low-temperature roasting, grinding and the like. Dry and wet epoxy resin powder can be used as a main raw material, sludge and calcium lignosulphonate are used as auxiliary materials to produce low-temperature cement which can be comparable with Portland cement and can also be mixed with other types of cement for use, and the low-temperature cement has the characteristicsof high cement strength, good concrete compatibility, good wear resistance, good frost resistance, small dry shrinkage, good corrosion resistance and the like when being used for constructional engineering construction. The production method also has the advantages of advanced and simple process technology, low energy consumption, high added value, investment saving, low cost, no secondary pollution, environmental protection and the like. In order to solve the problem that a large amount of industrial waste residue epoxy resin powder and other waste residues are consumed and reduce environmental pollution, the method is a good method which is beneficial to environmental protection and turns waste into wealth.

Description

technical field [0001] The invention belongs to the green environmental protection field of resource recycling, and in particular relates to a preparation method for producing a novel low-temperature cement by using epoxy resin powder, sludge and wood calcium. Background technique [0002] From home and abroad, there is no report on the use of industrial waste epoxy resin powder to produce building materials abroad and domestically. Instead, a large amount of waste epoxy resin powder is piled up and buried in a large amount of farmland, which seriously pollutes farmland and groundwater. For this reason, our country has increased the law enforcement of environmental protection and introduced various incentive policies to protect the environment and resources, achieve energy conservation, emission reduction, energy conservation, and comprehensive reuse of resources. At present, after the production of epoxy resin products in my country, the dry and wet waste liquid slag discha...
