Paraffin wax emulsions modified with petroleum resin and method of manufacturing the same

Abstract

The invention relates to the wax emulsion which uses the petroleum resin to modify and contains the paraffin wax, the petroleum resin, the oxidized wax, the paraffin emulsifier and water. The components are 2 per cent to 30 per cent paraffin wax, 2 per cent to 30 per cent the petroleum resin, 0.4 per cent to 12 per cent oxidized wax, 0.6 per cent to 12 per cent paraffin emulsifier and 16 per cent to 95 per cent water. The process steps of the preparation method are that (1) the raw materials are put in a high-pressure reactor and heated to about 100 DEG C. to melt; (2) the raw materials are stirred evenly at the speed of 400r/min; (3) half of the total water is heated to 95 DEG C. and poured with oil phase, and then is stirred at the speed of 800r/min to 1200r/min and emulsified for 10min to 30min; (4) the other half of the total water is added in the emulsified liquid at the normal temperature without heating and continuously stirred, and then reduces temperature to 40 DEG C. to discharge to produce the wax emulsion modified by the petroleum resin. The positive effect of the invention is that the wax emulsion modified by the petroleum resin can significantly improve the adhesion, the water resistance and the acid and alkaline resistance of the wax mask and greatly expand the properties and the purposes.

Description

【Technical field】 [0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a paraffin emulsion modified with petroleum resin and a preparation method thereof. 【Background technique】 [0002] In the 1950s, Mobil Oil Company began to research and develop emulsifying wax. By the 1960s, emulsifying wax was widely used in the United States. In the 1970s, the United Kingdom, the Federal Republic of Germany, and Japan also began to study and apply emulsifying wax. The research and application of emulsified paraffin in my country started relatively late, and the current main situation is: there are few varieties of emulsified paraffin, poor quality, and small production scale, which cannot meet the needs of various industries. [0003] Paraffin wax emulsion does not need to be heated and melted during use, uniform film formation, good coverage, and easy to mix and compound with other substances in aqueous solution or emulsion. It ...
