Abstract
The invention discloses a coal-to-liquid chlorinated paraffin with the thermal decomposition temperature of 180 ℃, which comprises the following components: 100 parts of coal-to-liquid chlorinated paraffin degassing base material, 0.2-0.5 part of epoxy compound and 0.2-0.3 part of heat stabilizer. According to the invention, the epoxy compound and the heat stabilizer are sequentially mixed with the degassing base material of the coal-based oil chlorinated paraffin for processing, so that the finished product of the coal-based oil chlorinated paraffin has high thermal decomposition temperature and good compatibility with downstream PVC resin, and the problems that the coal-based oil chlorinated paraffin is difficult to enter a high-end market due to low thermal stability for a long time and is limited in application are solved. The invention has potential market value.
Description
Technical Field
The invention relates to the field of chlorinated paraffin products, in particular to coal-to-liquid chlorinated paraffin with the thermal decomposition temperature of 180 ℃.
Background
The coal-made oil is also called coal liquefied oil, liquid fuel and chemical raw materials produced by taking coal as raw materials are used, wherein a part of the coal-made oil (coal paraffin) is an important raw material for producing chlorinated paraffin at present, the coal-made paraffin is much cheaper than the traditional petroleum-grade paraffin, the lower cost is also the main advantage of the production and popularization of the coal-made oil chlorinated paraffin, the foreign exchange expense of imported petroleum-grade paraffin is saved, and the domestic demand for the chlorinated paraffin is met.
However, the coal-based paraffin wax has high content of aromatic hydrocarbon, nitrogen, sulfur and other impurities and high content of isoparaffin, so that the prepared chlorinated paraffin wax product has deep color, much lower thermal stability than petroleum-grade chlorinated paraffin wax, obvious short performance and poor market competitiveness, can only be applied to middle and low-end products, and limits the market popularization of the product, so how to efficiently improve the thermal stability of the coal-based oil chlorinated paraffin wax to reach the quality standard of the petroleum-grade chlorinated paraffin wax becomes a technical difficulty which needs to be solved urgently in the field.
The improvement of the thermal stability of the coal-to-liquid chlorinated paraffin generally proceeds from two aspects: firstly, a degassing link is required to be made during the preparation of the chlorinated paraffin, the acid value of the product is strictly controlled, and the existence of HCl is reduced as much as possible, because the HCl has an autocatalysis effect in the chlorinated paraffin product, the chlorinated paraffin can be further decomposed, and the thermal stability of the chlorinated paraffin is influenced; secondly, HCl released by slow decomposition of the chlorinated paraffin is also influenced by long-time heating or illumination (ultraviolet rays) in the storage process, so that the heat stability of the chlorinated paraffin is improved by selecting a high-efficiency heat stabilizer.
Ethylene glycol diglycidyl ether is a traditional chlorinated paraffin stabilizer, but the chlorinated paraffin stabilizer with a single structure is limited to improve the thermal stability of the chlorinated paraffin for coal-derived oil and is expensive, and although some metal-containing chlorinated paraffin stabilizers have good effects, the chlorinated paraffin stabilizers have too much influence on the color of products and do not meet the requirements of economical and practical properties, high thermal stability and excellent yellowing resistance.
Disclosure of Invention
In order to solve the technical problem, the invention provides the coal-to-liquid chlorinated paraffin with the thermal decomposition temperature of 180 ℃.

Comparative experiment
(1) Congo Red test
The samples 1 to 9 and the comparative examples 1 to 5 are put into a test tube by sucking the same amount by a dropper at one time, a plug of Congo red test paper is hung below a plug of a test tube port, the position below the Congo red test paper is 2cm away from the edge of the upper liquid level of the material, the test tube is put into an oil bath pot and is slowly heated, and the temperature of the Congo red test paper changing into blue is recorded as the decomposition temperature.
(2) Color change experiment
The initial colorimetric values of the samples of examples 1 to 9 and comparative examples 1 to 5 were recorded, and the samples were placed in an experimental cabinet and kept in the dark for 30 days, and then the change in colorimetric value was measured.
(3) Temperature resistance test
80g of samples in examples 1-9 and comparative examples 1-5 are weighed respectively and placed into 100 ml of glass beakers, initial chroma is recorded, the glass beakers are placed in an oven with a rotating disk, and the color chroma value change of the product is observed after the glass beakers are placed at 180 ℃ for 60 min.
The results of experiments (1), (2) and (3) are shown in table 1.
Table 1 shows the results of experiments (1), (2) and (3)
As can be seen from Table 1, the chlorinated paraffins for coal oil prepared in examples 1 to 9 exhibited excellent thermal decomposition temperatures and discoloration resistance, both of which were above 180 ℃, not only significantly higher than those of comparative examples 1 and 4, but also performance comparable to or slightly higher than that of the petroleum-grade chlorinated paraffin for commercial use in comparative example 5. The improvement of the thermal decomposition temperature is beneficial to improving the temperature resistance of the coal-to-liquid chlorinated paraffin in the high-temperature processing process and inhibiting the color of the coal-to-liquid chlorinated paraffin from darkening under the high-temperature condition, thereby ensuring the color of downstream PVC products.
Comparative example 2 because epoxidized soybean oil was not added, comparative example 3 because epoxidized soybean oil was not added in advance, but was added simultaneously with a heat stabilizer, the thermal decomposition temperature was lower than that of examples 1 to 9, and the increase in chroma value was also greater when left to stand at high temperature for 60min, which shows that epoxidized soybean oil and the order of its placement also have a greater effect on the thermal stability of chlorinated paraffin of coal-derived oil.
