Embodiment 1

[0026] 100 parts by weight of rapeseed oil was added into the sulfonation reactor, and 150 parts by weight of 98%wt concentrated sulfuric acid was added dropwise while stirring at 50°C. After reacting for 5 hours, 2.5 parts by weight of methyl silicone oil with a viscosity of 2000 cps was added. Adding parts by weight is 5 parts of emulsifier in the above-mentioned mixture again, and described emulsifier is the compound that the NP-4 (NP is alkylphenol polyoxyethylene ether) of 20%wt and the Tween-80 composition of 80%wt compound. Then add an aqueous solution of triethanolamine with a concentration of 50% wt to the above mixture until the pH value of the mixture reaches 1, and stir at a high speed for 15 minutes to obtain the soil curing agent 1.

Embodiment 2

[0028] 100 parts by weight of castor oil were added into the sulfonation reactor, and 180 parts by weight of 98%wt concentrated sulfuric acid was added dropwise while stirring at 60°C. After reacting for 7 hours, 5.6 parts by weight of methyl silicone oil with a viscosity of 1000 cps was added. Then, 28 parts by weight of an emulsifier were added to the above mixture, and the emulsifier was a compound composed of 10% wt of Span-80 and 90% wt of Tween-20. Then add ethanolamine and sodium hydroxide to the above mixture with a concentration of 50%wt aqueous solution prepared according to the mass ratio of 1:1 until the pH value of the mixture reaches 1, and then stir at high speed for 20 minutes to obtain the soil curing agent 2.

Embodiment 3

[0030] 100 parts by weight of soybean oil are added into the sulfonation reactor, and 200 parts by weight of 98%wt concentrated sulfuric acid is added dropwise while stirring at 70°C. After reacting for 8 hours, 9 parts by weight of methyl silicone oil with a viscosity of 500 cps were added. Adding parts by weight in the above-mentioned mixture is 12 parts of emulsifier again, and described emulsifier is TX-10 (TX is the condensation product of alkylphenol and ethylene oxide) of 30%wt, the Span-60 of 25%wt and A compound composed of 45%wt Tween-60. Then add an aqueous solution of diethanolamine with a concentration of 50% wt to the above mixture until the pH value of the mixture reaches 1, and then stir at a high speed for 25 minutes to obtain the soil curing agent 3 .

Abstract

The invention provides a soil curing agent containing sulfonating animal and vegetable oil and a preparation method of the soil curing agent; the preparation method comprises the following steps: 100 parts of the animal and vegetable oil is added in a sulfonating reactor, 150-200 parts of concentrated sulfuric acid is added at 50-70 DEG C while being stirred, the reaction is carried out for 5-8 hours; 2.5-15 parts of silicone oil antifoaming agents are added after sulfonation reaction is finished; 5-45 parts of emulsifying agents are added in the mixture; aqueous alkali with proper amount is added in the mixture until the pH value of the mixture is 1, the mixture after being stirred is the soil curing agent; in the invention, animal and vegetable oil which is simple and easy-obtaining is used as raw materials, the cost is low, the preparation process only needs simple sulfonation reaction, and then the silicone oil antifoaming agents and emulsifying agents are added for uniform mixing, the method is simple; in the invention, the mechanical property and water stability of the soil can be enhanced, so as to be applied to industry in a large scale and have strong practical applicability.

Description

technical field [0001] The invention relates to a soil curing agent, in particular to a soil curing agent containing sulfonated animal and vegetable oils, and also relates to a preparation method of the soil curing agent containing sulfonated animal and vegetable oils. Background technique [0002] Soil curing agent refers to mixing materials synthesized from a variety of inorganic and organic materials into the soil to be reinforced, and then mixing and compacting to achieve the purpose of curing the soil. This kind of material synthesized from a variety of inorganic and organic materials The material is called a soil stabilizer. The use of soil curing agent can replace a large amount of traditional road construction materials such as lime, cement, fly ash, gravel, gravel, etc., which can not only save resources, energy, land, protect vegetation, but also greatly reduce the emission of greenhouse gases such as carbon dioxide. It is beneficial to the protection of the ecolo...
