Embodiment 1

[0024] (1) The waste oil of 100 parts by weight is sent in the processor, and the sodium bicarbonate of 5 parts by weight is added in the preprocessor, and the temperature in the control preprocessor is 80 ℃, continuously stirred for 20 minutes; Add 5 parts by weight of activated clay to the processor, raise the temperature of the preprocessor to 90° C., and continue stirring for 30 minutes to obtain the pretreated waste oil.

[0025] (2) 100 parts by weight of the pretreated waste oil prepared in the above steps is sent into the ammonolysis reactor; Stir continuously under the atmosphere for 100 minutes, make the waste oil undergo ammonolysis and transesterification reaction at medium temperature and normal pressure, and obtain the mixture of polyhydric alcohol and diethanolamine salt. Comparing the infrared spectrograms of the mixture in the reactor before and after the ammonolysis reaction, it was found that at 3633cm -1 The characteristic absorption of O-H appears nearby,...

According to the method of GB3399.82, the thermal conductivity coefficient of PU25 is 0.017W / (m·K), which is 106.25% of the thermal conductivity coefficient of PU00. Therefore, the compression performanc...

Embodiment 3

[0035] (3) in embodiment 1, self-made polyhydric alcohol and diethanolamine salt mixture replace the petroleum-based polyol of 50wt%, promptly add A component self-made polyhydric alcohol 50 weight parts in plastic cup, polyether polyol R180 is 50 parts by weight, and other conditions remain unchanged, and a rigid polyurethane foam material is prepared by a one-step method, which is denoted as PU50.

[0036] According to GBT6343-2009 "Determination of Apparent Density of Foam Plastics and Rubber", the apparent density of PU50 is 32.08kg / m 3 . According to GBT8813-2008 "Determination of Compressive Properties of Rigid Foam Plastics", the measured compressive strength of PU50 is 132kPa, and the compressive modulus is 1.4GPa, which are 88.40% and 94.00% of PU00, respectively. According to the GB3399.82 method, the thermal conductivity coefficient of PU50 is 0.019W / (m·K), which is 106.25% of the thermal conductivity coefficient of PU00. Therefore, the compression performance is...

Abstract

The invention relates to a method for preparing an organic high polymer foam material from drainage oil. The method comprises the steps of preprocessing the drainage oil, enabling the preprocessed drainage oil to join in an ammonolysis reaction with an amino compound to generate a polyol and an alcohol amine salt, taking the obtained polyol and alcohol amine salt as one of rigid foam polyurethane raw materials in stead of a petroleum-based polyol and mixing the obtained polyol and alcohol amine salt with isocyanate for reaction under the action of a foaming agent, a catalyst and a foam stabilizer to obtain a rigid foam polyurethane organic material excellent in comprehensive properties. Compared with the prior art, the method is simple in entire process, low in total cost, remarkable in profit and excellent in comprehensive properties. The method is advantageous for environmental protection and capable of saving petroleum resources, and therefore, a highly attractive way for high-value reutilization of the drainage oil is provided.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of waste oil, which belongs to the field of environmental protection and resource saving, in particular to a method for high-value reuse of waste oil. Background technique [0002] With the rapid development of the economy, the discharge of waste oil in my country has also increased rapidly. Waste oil contains a large amount of toxic and carcinogenic ingredients, long-term consumption can cause food poisoning, and even endanger life safety. Therefore, while improving relevant laws and regulations, it is necessary to develop high-value waste oil comprehensive utilization methods, so as to prevent waste oil from being returned to the dining table by criminals through improper means. [0003] There are mainly three ways for the comprehensive utilization of waste oil developed at present. One is to simply process and purify the waste oil, and directly use it as low-grade industrial oleic acid...
