Embodiment 1

[0038] The raw materials are alkylnaphthalene TM141 and alkylnaphthalene C4261 produced by Shanghai Zejun Trading Co., Ltd., and 37.0kg of long-chain alkylnaphthalene TM141 and 23.0kg of long-chain alkylnaphthalene C4261 are metered and pumped into the normal pressure blending kettle, heated to 40-60°C.

[0039] The remaining 28.0kg of long-chain alkylnaphthalene TM141 and 12.0kg of long-chain alkylnaphthalene C4261 were heated to 80-90°C in a small heating device, and then 1.0kg of antioxidant additive carbamate 996E, 4.0kg of Hydrophobic agent 52# paraffin, 0.02kg of antifungal agent 3Q-621OIT, 0.003kg of fungicide heptylparaben, 0.25kg of ultraviolet radiation absorber 329, 0.04kg of anti-emulsifier T1001 are measured and added to the long chain Alkyl naphthalene TM141 and long-chain alkyl naphthalene C4261 mixed solution, stir evenly to make mother liquor.

[0040] Add the above-prepared mother liquor into the blending tank and stir evenly to obtain the synthetic industri...

Embodiment 2

[0042] The raw material is alkylnaphthalene AN23 from Shanghai Naco Lubrication Technology Co., Ltd., and 60.0kg of long-chain alkylnaphthalene AN23 is metered and pumped into an atmospheric pressure mixing kettle and heated to 40-60°C.

[0043] The remaining 40.0kg of long-chain alkyl naphthalene AN23 is heated to 80-90°C, and then 1.0kg of antioxidant additive carbamate 996E, 4.0kg of hydrophobic agent 52# paraffin, and 0.02kg of antifungal agent 3Q-621OIT , 0.003kg of fungicide heptylparaben, 0.25kg of ultraviolet radiation absorber 329, 0.04kg of anti-emulsifier T1001 metered and sequentially added to the long-chain alkyl naphthalene AN23 solution, stirred evenly to form a mother liquor.

[0044] Add the above-prepared mother liquor into the kettle and stir evenly to obtain the synthetic industrial acidic waste water vapor barrier agent of this embodiment.

[0045] Use the blend of long-chain alkylnaphthalene TM141 and alkylnaphthalene C4261 or the single compound of alkyl...

Abstract

The invention relates to a synthetic material combination technology, in particular to a synthetic industrial acidic wastewater vapor blocking agent and a preparation method thereof. The blocking agent is prepared from, by weight, 100 parts of long-chain alkyl naphthalene of which the carbon number is greater than or equal to eight and 4-10 parts of functional additives. The blocking agent is low in specific gravity, thereby being capable of floating on the acidic wastewater and blocking the water vapor; the blocking agent is high in flash point, thereby being small in saturated vapor pressure, low in volatility and small in evaporation loss. Meanwhile, the blocking agent is excellent in emulsion resistance and hydro-dissection capacity, prominent in oxidation stability and thermal stability, low in product aging speed and also excellent in mould prevention and has wide adaptability to the pH value of acidic water; besides, the blocking agent is low in toxicity, safe in operation and small in environmental influence. In addition, the blocking agent is easy and convenient to use and can be directly poured, there is no need to stop work or production, the subsequent working procedures and product quality will not be affected, and the blocking agent is also convenient to recover; moreover, the blocking agent can be generally used in the four seasons.

Description

technical field [0001] The invention relates to a synthetic material combination technology, in particular to a synthetic industrial acidic waste water vapor barrier and a preparation method thereof. Background technique [0002] Most of the blast furnace slag flushing in the ironworks of the iron and steel industry uses industrial wastewater containing a large amount of various acidic chemical substances recycled in the iron and steel plant, such as coking wastewater. Due to the high temperature of industrial wastewater, in the colder season, steam is rising around the slag pool, and clouds and mist surround it. When people get close, they feel pain in the eyes and throat. In severe cases, they even cough immediately and have to flee immediately. Therefore, its production and working environment is very harsh, especially in summer. [0003] In the past two years, as my country's environmental protection requirements have become higher and higher, environmental protection l...
