Embodiment 1

[0036] The ratio of raw materials in this embodiment is 50% of oilfield sludge, 20% of river sand, 25% of aluminophosphate cement, and 5% of curing agent from Shengli Oilfield Xianhe Oil Production Plant.

[0037] Wherein, the curing agent is mixed with the raw materials in the following weight ratio:

[0038] Magnesium Oxide: 25%, Calcium Chloride: 25%, Gypsum: 25%, Lime: 25%.

[0039] Wherein, the aluminophosphate cement is composed of 45% (w / %) ternary calcium aluminophosphate solid solution, 25% (w / %) calcium aluminate solid solution, 25% (w / %) calcium phosphate solid solution phase and 5% (w / %) vitreous composition.

[0040] The production method is:

[0041] c) Colored cement is used for the color surface, and it is fully mixed with white crushed stone at a ratio of 1:2.5, and mixed with water according to the water-cement ratio of 0.5 to make a slurry; inject the slurry into the mold with a thickness of 1-2cm, and place it for half an hour ;

[0042] d) Mix the abov...

Embodiment 2

[0049] The ratio of raw materials in this embodiment is 62% of oilfield sludge, 17% of river sand, 18% of aluminophosphate cement, and 3% of curing agent in Hekou Oil Production Plant of Shengli Oilfield.

[0050] Wherein, the curing agent is mixed with the raw materials in the following weight ratio:

[0051] Magnesium Oxide: 30%, Calcium Chloride: 20%, Gypsum: 30%, Lime: 20%.

Abstract

The invention relates to a ground brick and a production method thereof, in particular to a ground brick produced by using oil field sludge and the production method thereof. Matrix material of the ground brick consists of raw materials by weight proportion as follows: 50-70 percent of the oil field sludge, 10-25 percent of riversand, 15-25 percent of phosphoaluminate cement and 3-5 percent of hardener; the hardener consists of the raw materials by the weight proportion as follows: 20-30 percent of magnesia, 20-30 percent of calcium chloride, 20-30 percent of gypsum and 20-30 percent of lime. The ground brick of the invention has the advantages of high strength, low water absorption, low cost and no pollution which meets the requirement of the ecological environment protection and solves the problems of pollution and discharge of the oil field sludge.

Description

technical field [0001] The invention relates to a floor tile and a production method thereof, in particular to a floor tile made from oil field sludge and a production method thereof. Background technique [0002] In the process of oil production, a large amount of oil well sludge will be produced, and these numerous oil well muds generally contain a large amount of heavy metals, oils, alkalis and chemicals (including organic matter), which are extremely harmful to people, animals and the environment. If mud is discarded after use, if it is not treated, these substances will seriously pollute the environment, endanger people's life and health, and affect the growth and development of animals and plants. The treatment and application of oily sludge is a difficult problem in the process of oily sewage treatment. [0003] In terms of comprehensive utilization of oily sludge, the main direction of utilization is the research of building materials, that is, oilfield sludge is co...
