Problems solved by technology

[0005] Ethylene glycol diglycidyl ether is a traditional chlorinated paraffin stabilizer, but its single structure is used to improve the thermal stability of coal-to-oil chlorinated paraffin, and the price is expensive. Although some metal-containing chlorinated paraffin stabilizers are effective , but it has too much influence on the color of the product, which does not meet the requirements of economical and practical, high thermal stability and excellent yellowing resistance

Abstract

The invention discloses a coal-to-oil chlorinated paraffin with a thermal decomposition temperature of 180°C, which comprises the following components: 100 parts of coal-to-oil chlorinated paraffin degassing primer, 0.2-0.5 parts of epoxy compound, and 0.2 parts of heat stabilizer ~0.3 parts. In the present invention, epoxy compound and heat stabilizer are sequentially mixed with coal-to-oil chlorinated paraffin degassing base materials, so that the thermal decomposition temperature of the coal-to-oil chlorinated paraffin finished product is high, and the compatibility with the downstream product PVC resin is good, which solves the problem of Coal-to-oil chlorinated paraffins have long been difficult to enter the high-end market and have limited applications due to low thermal stability. The invention has potential market value.

Description

technical field [0001] The invention relates to the field of chlorinated paraffin products, in particular to a coal-to-oil chlorinated paraffin with a thermal decomposition temperature of 180°C. Background technique [0002] Coal-to-oil, also known as coal liquefied oil, is a liquid fuel and chemical raw material produced from coal. Part of coal-to-oil (coal-to-paraffin) is an important raw material for the production of chlorinated paraffin. This coal-to-paraffin is relatively Grade paraffin is much cheaper, and the lower cost is also the main advantage of coal-to-oil chlorinated paraffin production and promotion. It not only saves the foreign exchange expenditure of imported petroleum grade paraffin, but also meets the domestic demand for chlorinated paraffin. [0003] However, coal-based paraffin contains high impurities such as aromatics, nitrogen, and sulfur, and isoparaffins. Therefore, the prepared chlorinated paraffin products have dark color and much lower thermal s...
