Problems solved by technology

Its disadvantages are: a. The paraffin emulsifier is in a liquid state, which is not convenient for transportation and use; b. The manufacturing process is complicated and requires heating and reaction; c. The paraffin emulsifier is also used in a large amount when emulsifying paraffin, and the amount added is about 20% of the added amount, the use cost is higher

Embodiment 1

[0010] Embodiment 1: Get 20 parts of lauryl alcohol, 20 parts of ethylene oxide, 40 parts of monoglycerides, 5 parts of stearic acid, and 5 parts of ethanol, and react in a common reactor at normal temperature and pressure. First, the lauryl alcohol and ethylene oxide of the component are added into the reactor to carry out a chemical reaction to form a copolymer of the two, then the monoglyceride, stearic acid, and ethanol of the component are added, and the mixture is evenly mixed, that is, Can be made into solid or paste paraffin emulsifier.

Embodiment 2

[0011] Embodiment 2: Get 25 parts of lauryl alcohol, 25 parts of ethylene oxide, 45 parts of monoglycerides, 10 parts of stearic acid, and 10 parts of ethanol, and react in an ordinary reactor at normal temperature and pressure , firstly adding the lauryl alcohol and ethylene oxide of the components into the reactor to carry out a chemical reaction to form a copolymer of the two, then adding the monoglyceride, stearic acid and ethanol of the components, stirring and mixing evenly, It can be made into solid or paste paraffin emulsifier.

Embodiment 3

[0012] Embodiment 3: Get 30 parts of lauryl alcohol, 30 parts of ethylene oxide, 50 parts of monoglyceride, 15 parts of stearic acid, and 15 parts of ethanol, and react in a common reactor at normal temperature and pressure , firstly adding the lauryl alcohol and ethylene oxide of the components into the reactor to carry out a chemical reaction to form a copolymer of the two, then adding the monoglyceride, stearic acid and ethanol of the components, stirring and mixing evenly, It can be made into solid or paste paraffin emulsifier.

[0013] The following will adopt this emulsifier to prepare the main steps of paraffin wax emulsion as follows: put paraffin wax and this emulsifier relative to the amount of paraffin wax addition (weight) of about 4%-5% in the reactor with agitator and stir, emulsify The time is kept at about 20 minutes. Then add the dilution water for the first time, and the addition amount is about 35%-45% of the total dilution water. The water temperature is ...

Abstract

The invention provides a paraffin emulsifier and its making method, wherein the emulsifier comprises lauryl alcohol, ethylene oxide, monoester, stearinic acid and ethanol, and solid or grease form ceresin wax emulsifying agent can be obtained through reaction in common autoclaves.

Description

[0001] Field [0002] The invention relates to a paraffin emulsifier, and also relates to a preparation method of the paraffin emulsifier. Background technique [0003] Conventional paraffin wax emulsifiers have disadvantages such as large consumption, high cost, and ammonia irritating odor. The most important thing is that the paraffin wax emulsion prepared by using this emulsifier will break and separate out when encountering acidic or alkaline media, and the operation process of this emulsifier is difficult. The particles of paraffin emulsion are coarse and unstable in storage. [0004] The CN1022805C patent proposes a paraffin emulsifier consisting of the following components: sodium alkylbenzenesulfonate and / or sodium alkylsulfonate, alkanolamide, tea saponin, dodecyldimethylbenzyl chloride Ammonium, Polyvinyl Alcohol, Sodium Tripolyphosphate and / or Sodium EDTA, Urea and Absolute Ethanol. Its disadvantages are: a. The paraffin emulsifier is in a liquid state, which is n...
