[0063] The ratio of raw materials in this embodiment is 30% of oilfield sludge, 40% of river sand, 26% of cement, and 4% of curing agent.

[0064] Wherein, the curing agent is mixed with the raw materials in the following weight ratio:

[0065] Sulfoaluminate: 22% Calcium Stearate: 5%

[0066] Calcium Chloride: 20% Calcium Acetate: 0

[0067] Fluorite: 0 Gelatin: 5%

[0068] Gypsum: 20% Lime: 18%

[0069] Acrylic resin 0

[0070] Core material: 10%

[0071] CaO

[0072] The production method is:

[0073] a) Colored cement is used for the color surface, and it is fully mixed with white gravel at a ratio of 1:2.5, and water is added to mix evenly 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 ;

[0074] b) Mix the above-mentioned oilfield sludge, river sand, cement, fly ash, and curing agent evenly, inject it into the above-mentioned mold, vibrate on the vibrat...

Embodiment 2

[0079] The raw material ratio of the matrix in this embodiment is 40% of oilfield sludge, 20% of river sand, 20% of cement, 19% of fly ash, and 2% of curing agent.

[0080] Wherein, the curing agent is mixed with the raw materials in the following weight ratio:

[0081] Sulfoaluminate: 15% Calcium Stearate: 2%

[0082] Calcium Chloride: 10% Calcium Acetate: 15%

[0083] Fluorite: 10% Gelatin: 9%

[0084] Gypsum: 10% Lime: 25%

[0085] Acrylic 4%

[0086] The production method is the same as in Example 1, and the floor tiles are made.

[0087] The performance test results are: the average compressive strength is 22.28, the water absorption rate is 7.34%, and the bulk density is 1.96g / cm 3 . Its mechanical properties can still meet the relevant national standards. Other properties are substantially the same as in Example 1.

Embodiment 3

[0089] The ratio of raw materials in this embodiment is 55% of oilfield sludge, 20% of river sand, 18% of cement, and 7% of curing agent.

[0090] Wherein, the proportioning of curing agent is:

[0091] Sulfoaluminate: 20% Calcium Stearate: 5%

[0092] Calcium Chloride: 15% Calcium Acetate: 10%

[0093] Fluorite: 0 Gelatin: 5%

[0094] Gypsum: 15% Lime: 10%

[0095] Acrylic resin 0 Monoethylene glycol 5%

[0096] Sucrose 5%

[0097] Core material: 10%

Abstract

The present invention relates to floor tile, and is especially floor tile made of oil field sludge and curing agent and its production process. The floor tile has the main material comprising oil field sludge 30-60 wt%, river sand 15-40 wt%, cement 15-30 wt%, flyash 0-35 wt% and curing agent 1-8 wt%. The floor tile of the present invention has high strength and no pollution and reaches the requirement of protecting ecological environment. The present invention solves the problem of pollution caused by oil field sludge, and the floor tile producing process is simple.

Description

(1) 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. (2) Background technology [0002] Oil well mud is the blood of oil drilling engineering. With the development of the petroleum industry, the output of oil well mud is increasing, and these numerous oil well muds generally contain a large amount of heavy metals, oils, alkalis and chemicals (including organic matter) substances that are extremely harmful to humans, 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. [0003] The treatment and application of oily sludge is a difficult problem in the process of oily sewage treatment. Western Europe and the United States have used biotechnology, physical and chem...
