Description
Technical Field
The application relates to the field of C09K8/584, in particular to an oil body fluid sealing composition and a preparation method thereof.
Background
At present, some liquid materials are used as sealants for safety protection of oil bodies, and liquid seals can be formed on the surface of the oil bodies so as to reduce the generation of harmful gases such as VOC (volatile organic compounds) and the like, thereby reducing the harm to staff and the danger of explosion; however, the existing liquid sealing material for the surface of the oil body has the problems of serious safety and environmental protection caused by low spreading speed on the surface of the oil body, low coverage rate of the surface of the oil body and insufficient adhesive force stability, and has higher cost and lower use efficiency, and cannot meet the actual use requirement.
Chinese patent CN108219473a discloses a room temperature vulcanized ceramic silicone rubber foam sealant and a preparation method thereof, and uses ceramic additive, alpha, omega-dihydroxy polydimethylsiloxane and vinyl silicone oil as main raw materials to provide a foam sealant with stable structure and excellent insulating property, but is not suitable for liquid seal of oil body surface. Chinese patent CN1445326a discloses an alkaline battery sealant reinforced by environment-friendly nano materials, which adopts epoxy resin and polyolefin as main raw materials, and cooperates with nano additives with certain mass, so as to remove toluene and xylene from the alkaline battery sealant, thereby achieving mandatory national standard and solving the environmental protection problem, but failing to provide a liquid sealing material for effectively preventing volatilization of harmful gases such as VOC in oil.
Therefore, the oil body sealing composition provided by the application has the advantages of high oil body surface coverage rate and high spreading speed on the oil body surface, and can effectively prevent volatilization of harmful gases such as VOC and the like in the oil body for a long time, and has important practical research and application significance.
Disclosure of Invention
The application provides an oil body fluid sealing composition, which is prepared from the following raw materials in parts by weight: 6-12 parts of cationic surfactant, 7-18 parts of nonionic surfactant, 5-10 parts of block polyether, 5-10 parts of polysiloxane, 2-5 parts of phosphate compound, 0.05-0.3 part of functional auxiliary agent and 70-100 parts of deionized water.
As a preferable technical scheme, the cationic surfactant is an amine oxide compound; preferably, the amine oxide compound is at least one selected from cocoamidopropyl dimethyl amine oxide, dodecyl dimethyl amine oxide, oleamidopropyl dimethyl amine oxide and dodecyl dimethyl benzyl amine oxide; preferably, the amine oxide compound is a combination of cocoamidopropyl dimethyl amine oxide, oleamide propyl dimethyl amine oxide and dodecyl dimethyl benzyl amine oxide, and preferably, the mass ratio of cocoamidopropyl dimethyl amine oxide, oleamide propyl dimethyl amine oxide and dodecyl dimethyl benzyl amine oxide is (4-6): (2-4): (1-2) can improve the dispersion degree of the system in cooperation with the nonionic surfactant in the system, form a water film on the surface of the oil body, protect the effective components in the oil body and reduce the generation of harmful gases such as VOC.
The cocoamidopropyl dimethyl amine oxide was purchased from billions of technology limited in Hangzhou; the oleamide propyl dimethyl amine oxide is purchased from new materials limited company, shanghai bo; the dodecyl dimethyl benzyl amine oxide was purchased from Shanghai Ala Biochemical technologies Co., ltd.
Although the volatilization of harmful gases such as VOC and the like can be reduced to a certain extent, the spreading speed on the surface of the oil body is slow, and the effective components are easy to volatilize and lose efficacy, and as a preferable technical scheme, the nonionic surfactant is selected from one or more of alkylphenol ethoxylates, fatty acid ethoxylates, fatty alcohol ethoxylates and glyceryl monostearate; preferably, the nonionic surfactant is a combination of fatty alcohol polyoxyethylene ether and glyceryl monostearate, and the inventor finds that, in the research process, when the mass ratio of the fatty alcohol polyoxyethylene ether to the glyceryl monostearate in the system is (1-3): (0.8-1.2), the obtained oil body sealing composition can be rapidly spread on the surface of the oil body, so that the coverage rate of the surface of the oil body is effectively improved, and volatilization of harmful gases such as VOC and the like is effectively reduced.
The fatty alcohol polyoxyethylene ether is purchased from Beijing company of chemical summer; the glyceryl monostearate had a CAS number of 123-94-4 and was purchased from Shanghai Seiyaku Biotechnology Co.
As a preferable technical scheme, the functional auxiliary agent is one or more selected from sodium chloride, potassium chloride and lithium chloride, preferably, the functional auxiliary agent is a combination of sodium chloride and lithium chloride, and the inventor surprisingly discovers that, especially when the mass ratio of the sodium chloride to the lithium chloride is (1.5-2): (1-1.6), the spreading speed and spreading capacity of the oil body fluid sealing composition are obviously improved, and the oil surface coverage rate is effectively improved.
The inventor finds that, in the research process, when the mass ratio of the nonionic surfactant to the functional auxiliary agent is (10-15): when the water film is in a range of 0.15-0.23, a certain thickening effect is achieved on the system, the formed water film is thin and compact, volatilization of harmful gases such as VOC and the like in an oil body is effectively reduced, sedimentation cannot occur, the water film can be covered on the surface of the oil body for a long time, and the water film is thin and light due to the existence of sodium chloride and lithium chloride, so that the spreading speed and the oil body surface coverage rate of the oil body sealing composition are effectively improved; on the other hand, the introduction of sodium chloride and lithium chloride compresses an electric double layer in the nonionic surfactant, increases the aggregation number of the micelles, contributes to improving the compactness degree of a water film, and further effectively prevents volatilization of harmful gases such as VOC in an oil body.
In order to enable the provided oil body fluid sealing composition to effectively act on an oil body for a long time, as a preferable technical scheme, the block polyether is propylene glycol block polyether, the propylene glycol block polyether is selected from one or a combination of a plurality of L63, L64, F68, P65 and P84, preferably, the propylene glycol block polyether is L64 and has the most suitable hydrophilic-lipophilic balance value, and the fatty alcohol polyoxyethylene ether in a synergistic system improves the adhesion of the oil body fluid sealing composition on the surface of the oil body and simultaneously improves the speed of forming a water film on the surface of the oil body.
The L64 propylene glycol block polyether was purchased from Shanghai high chemistry Co.
As a preferred embodiment, the polysiloxane is at least one selected from the group consisting of polydimethylsiloxane, cyclomethicone, aminosilicone, polymethylphenylsiloxane, polyether polysiloxane copolymer; preferably, the polysiloxane is polydimethylsiloxane, especially trimethylsiloxane end-capped polydimethylsiloxane with an average molecular weight of 2000-6000, and glyceryl monostearate in a synergistic system can obviously improve the spreading capability of the oil body fluid sealing composition on the surface of an oil body, realize the whole surface coverage of the oil body, effectively isolate harmful gases such as VOC and the like from contacting with the external environment, reduce unnecessary safety problems and be beneficial to environmental protection.
The polydimethylsiloxane has a CAS number of 9016-00-6 and a product model of Alfa Aesar-042500, and is purchased from Beijing carbofuran technology Co.
