Description
Technical field
The present invention relates to food grade lubricating oil, especially a kind of food grade lubricating oil and preparation method take average sucrose polyfatty acid esters as base oil.
Background technology
Food machinery lubricating oil is an important factor that affects food safety, is the indispensable material of foodstuff production, and inevitable lubricating oil and food contacts in the foodstuff production.Food grade lubricating oil is safer to food, and non-food product lubricating oil contains the toxic composition of part, and use can bring food safety hidden danger.At present part domestic enterprise as food machinery lubricating oil, its security is not high with animal oil, medical ventolin, also there is a big difference with the quality of developed country like product, the food of production is difficult to reach American-European to be waited the requirement of developed regions and is difficult to export.It all is from external import that the food grade lubricating oil that export food enterprise and pharmacy corporation are used is gone up substantially, in technology and all under one's control in price, is unfavorable for that domestic enterprise takes part in international competition.
Food grade lubricating oil is comprised of base oil and additive usually.The domestic main refined mineral oil of base oil and modified vegetable oil obtains at present, correlative study such as Sinopec company are take the mineral oil of deep refining as base oil, patent such as application number CN200780044509.4, a kind of lubricating composition is disclosed, take mineral oil and/or synthetic oil as base oil, additive can contain a small amount of sucrose fatty ester (consumption is 0.2%-18%).At present, the mineral lubricating oils of China take the petroleum refining thing as base oil accounts for 97.7% of production, but oil is a kind of non-renewable rare energy, and the biological degradability of mineral lubricating oils is relatively poor, is lost in the environment ecosystem is caused huge harm.The impact of mineral lubricating oils polluted underground water can reach 100 years, and the mineral oil of trace can hinder plant-growth and poison hydrobiont.Therefore, development of new base oil proxy mineral oil become the task of top priority (Zhang Qiang, Li Wenlin, Liao Lee, Huang Fenghong. the progress ［ C ］ of the friendly type lubricating oil of vegetables oil conversion environment, Chinese oil, 2008,33(9): 36.).
What domestic research was more in recent years is to adopt eco-friendly Vegetable oil lipoprotein to carry out modification to obtain base oil, vegetables oil has preferably viscosity-temperature characteristic and good lubricity, renewable, free from environmental pollution, take vegetables oil as lubricant base, having the mineral lubricating oils of minimizing pollution on the environment and successfully managing is the double meaning that resource exhaustion is arranged.Patents is as follows:
1. application number: CN03823615.X, the applicant: Vegaoils Ltd OY, a kind of lubricating oil and uses thereof is disclosed, adopt lubricity of turnip rapeseed oil or rapeseed oil as main component, auxiliary lubricant can contain sucrose fatty ester as emulsifying agent;
2. application number: CN200480014998.5, the applicant: Renewable Lubricants, a kind of food-grade-lubricant of improvement is disclosed, it comprises a) at least a triglyceride oil; B) at least a polyalphaolefin and c) at least a antioxidant.Triglyceride oil is selected from vegetables oil of crude vegetal, synthetic vegetables oil, genetic modification and composition thereof, and said composition also contains at least a food-grade oil, is selected from oil of synthetic ester, white oil, hydrocracking and composition thereof.
3. application number: CN200710122083.1, the applicant: Tsing-Hua University, a kind of preparation method of lubricating oil is disclosed, be take vegetables oil such as soya-bean oil, rapeseed oil, Trisun Oil R 80, cottonseed wet goods as raw material, it is carried out chemical modification.
4. application number: CN201010141684.9, the applicant: Northeast Agricultural University discloses a kind of at supercritical CO
2The method of developing lube base oil with hydrogenated soybean oil under the state has adopted soybean oil as lubricant base, compares with general industry lubricating oil, has improved comestible composition in the lubricating oil, has reduced toxic side effect.
Although vegetables oil has the advantages such as nontoxic, that biological degradation rate is high, lubricity good and viscosity index is high, regenerative power is strong as the base oil of environmentally friendly lubricating oil, but it is poor also to exist oxidation stability simultaneously, the shortcomings such as low-temperature performance and stability to hydrolysis are poor, this has limited the application of vegetables oil to a great extent.
Sucrose polyfatty acid esters (sucrose polyester, SPE) is commonly referred to as the above sucrose ester of three esters.Its chemical structural formula is:
Wherein, R=H or CH
3(CH
2) n-C=O.
Sucrose polyfatty acid esters has high security, good lubricity, can be used as the base oil of food grade lubricating oil.The sucrose polyfatty acid esters raw material sources is wider, belongs to sustainable renewable resource.Under the environment that the domestic food safety problem takes place frequently, the foreign foods technology barriers improve constantly, world's oil resources is day by day in short supply at present, urgent need will be sought the more food grade lubricating oil of high quality, renewable resources production.Application number: 201110102418.X, applicant: Guangxi University, a kind of universal machinery lubricating oil in pharmaceutical industry is disclosed, its one-tenth is grouped into and is: base oil 80 ~ 95%, oxidation inhibitor 1.5 ~ 8%, anti-wear agent 0.5 ~ 5%, rust-preventive agent 1.0 ~ 5%, low friction compound 0.1 ~ 3%, slip additive 0.3 ~ 4%, having adopted sucrose polyfatty acid esters is base oil, and increased new composite additive, make the lubricating oil over-all properties surpass traditional mineral oil, have satisfactory stability, oxidation-resistance, rust-preventing characteristic, biological degradability can prolong the oil draining period, reduce the processing costs of waste liquid, lowering energy consumption and total cost of production, is the product of the higher and environmental protection of cost performance, is beneficial at food, health and pharmaceutical industry are promoted the use of.But this invention has 3 weak points: the one, do not define the gamma value of sucrose polyfatty acid esters, and they be to be solid-state under 3 ~ 5 the sucrose ester normal temperature such as gamma value, and usage ratio is up to 80 ~ 95%, and this system is difficult to make lubricating oil; The 2nd, be not that the quality standard of sucrose polyfatty acid esters is made requirement to the product main raw material; The 3rd, use sulfur-containing additive, do not control the sanitary quality index of lube product.Do not meet the quality safety that base oil that food sanitation requires will jeopardize lubricating oil, the lubricating oil that uses sulfur-containing additive and heavy-metal residual to exceed standard can cause the pollution of food, medicine equally.
Summary of the invention
