Abstract

The invention discloses an emulsified paraffin which is prepared from the following raw materials in parts by weight: 100-150 parts of modified paraffin, 10-18 parts of phosphite, 11-16 parts of tert-butylhydroquinone, 18-27 parts of sodium silicate, 6-9 parts of calcium stearate, 5-15 parts of methyl amyl alcohol, 10-25 parts of triethyl hexyl phosphoric acid and 22-32 parts of emulsifier. The emulsifier is a mixture of calcium stearoyl lactylate, ethylene glycol and calcium dodecylbenzene sulfonate. The emulsified paraffin has the advantages of high stability, favorable flowability, small emulsified paraffin particles and high emulsified paraffin content. The modified paraffin improves the viscosity of the liquid paraffin. The phosphite and tert-butylhydroquinone enhance the aging resistance of the emulsified paraffin. The sodium silicate, calcium stearate, methyl amyl alcohol and triethyl hexyl phosphoric acid enhance the water resistance and flowing property of the emulsified paraffin. The mixture of the calcium stearoyl lactylate, ethylene glycol and calcium dodecylbenzene sulfonate used as the emulsifier has favorable emulsifying effect.

Description

technical field [0001] The invention relates to an emulsified paraffin, which belongs to the technical field of industrial chemicals. Background technique [0002] Paraffin is one of the solid crystalline products extracted from petroleum. Paraffin is a kind of aliphatic hydrocarbon, which is a mixture of various hydrocarbons, that is, hydrocarbons of different molecular weights. It is mainly composed of normal alkanes, and also contains some solid isoparaffins, cycloalkanes and a small amount of aromatics; Or branched carbon chain, and contains normal alkanes, the general formula CnH2n+2, n is the number of carbon atoms in the hydrocarbon chain (n=17~36). The molecules composed of the paraffin crystal layer have a planar zigzag conformation, and the molecular length and melting point only depend on n. Paraffin wax is a mixture of white, translucent, tasteless and odorless solids. The relative molecular weight of solid hydrocarbons is relatively high. The distillation rang...
