Embodiment 1

[0024] (1) Send 100 parts by weight of waste oil into the processor, add 5 parts by weight of sodium bicarbonate to the preprocessor, control the temperature in the preprocessor to 80°C, and continuously stir for 20 minutes; 5 parts by weight of activated clay was added to the processor, and the preconditioner was heated to 90° C., and then continuously stirred for 30 minutes to obtain pretreated waste oil.

[0025] (2) Send 100 parts by weight of the pretreated waste oil prepared in the above steps into the ammonolysis reactor, add 20 parts by weight of diethanolamine and 10 parts by weight of sodium ethoxide, and control the temperature in the pretreatment device to 100°C. Continuous stirring under the atmosphere for 100 minutes to cause the waste oil to undergo ammonolysis and transesterification at medium temperature and normal pressure to obtain a mixture of polyol and diethanolamine salt. Comparing the infrared spectra of the mixture in the reactor before and after the ammo...

Embodiment 2

[0032] In Example 1, (3), the mixture of self-made polyol and diethanolamine salt replaces 25wt% of petroleum-based polyol, that is, 25 parts by weight of component A self-made polyol is added to the plastic cup, polyether polyol R180 is 75 parts by weight, and other conditions are kept unchanged. A rigid foam polyurethane material is prepared by a one-step method, which is recorded as PU25.

[0033] According to GBT6343-2009 "Determination of Apparent Density of Foam Plastic and Rubber", the apparent density of PU25 is measured to be 35.67kg / m 3 . According to the GBT8813-2008 "Determination of the Compression Performance of Rigid Foam Plastics" standard, the measured PU25 compressive strength is 157kPa and the compression modulus is 1.74GPa, which are respectively 95.73% and 95.08% of PU00. According to the GB3399.82 method, the thermal conductivity coefficient of PU25 is 0.017W / (m·K), which is 106.25% of the thermal conductivity of PU00. Therefore, the compression performance...

Embodiment 3

[0035] In Example 1 (3), the mixture of self-made polyol and diethanolamine salt replaces 50wt% of petroleum-based polyol, that is, 50 parts by weight of component A self-made polyol is added to the plastic cup, polyether polyol R180 is 50 parts by weight, and other conditions are kept unchanged. A rigid foam polyurethane material is prepared by a one-step method, which is recorded as PU50.

[0036] According to GBT6343-2009 "Determination of Apparent Density of Foam Plastic and Rubber" standard, the apparent density of PU50 measured is 32.08kg / m 3 . According to the GBT8813-2008 "Determination of the Compression Properties of Rigid Foam Plastics" standard, the measured PU50 compressive strength is 132kPa and the compression 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 of PU00. Therefore, the compression performance...

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, belonging 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 economic development, the emissions of waste oil in my country have also increased rapidly. Waste oil contains a lot of toxic and carcinogenic ingredients, long-term consumption will cause food poisoning, and even endanger life. Therefore, while improving relevant laws and regulations, it is necessary to develop high-value comprehensive utilization of waste oil, so as to prevent waste oil from being returned to the table by illegal elements through illegal means. [0003] There are three main methods for the comprehensive utilization of waste oil developed at present. One is to simply process and purify waste oil and directly use it as low-grade industrial oleic acid, stearic acid and industrial grease. For...
