Abstract

The present invention discloses a paraffin emulsifier and a preparation method thereof. The paraffin emulsifier is composed of 20 to 30 portions of lauryl alcohol, epoxyethane, monostearin, stearic acid and alcohol, and the materials react in a common reaction kettle. Thereby, a solid or pasty paraffin emulsifier can be prepared. The use level is low when the emulsifier is utilized to produce the paraffin emulsion; the use level of the emulsifier is only 4% to 5% of the use level of the paraffin. The produced paraffin emulsion does not have toxin, taste, layering phenomenon or emulsion breaking phenomenon but have strong stability, good lubricity, acid resistance alkali resistance and hard water resistance. Moreover, the emulsion of which the paraffin solid content is more than 50% can be produced, and the water solubility of the emulsion is high. The paraffin emulsifier can serve as an industry auxiliary agent to be widely used for textile field, papermaking field, etc., and can also directly serve as a demoulding agent. In artificial fiber board industry, the paraffin emulsifier can completely replace paraffin and serve as a waterproof auxiliary agent and a moisture protection auxiliary agent. Moreover, compared with the paraffin, the paraffin emulsifier has simpler use, lower cost and more favorable effect.

Description

A kind of paraffin emulsifier and preparation method thereof

Affiliated field

The present invention relates to a kind of paraffin emulsifier, also relate to the preparation method of described paraffin emulsifier.

Background technology

Routine paraffin wax emulsifying agent consumption is big, cost is high, shortcomings such as ammoniacal liquor pungent odour are arranged, most importantly the paraffin wax emulsions that utilizes this emulsifying agent to make is met acidity, alkaline medium can be separated out by breakdown of emulsion, and the operating procedure difficulty of this emulsifying agent, the particle of paraffin wax emulsions is thick, stores unstable.

The CN1022805C patent has proposed a kind of paraffin emulsifier of being made up of following component: sodium alkyl benzene sulfonate and/or alkyl sodium sulfonate, alkylol amide, tea saponin, dodecyl dimethyl benzyl ammonium chloride, polyvinyl alcohol, tripoly phosphate sodium STPP and/or sodium ethylene diamine tetracetate, urea and dehydrated alcohol.Its shortcoming is: this paraffin emulsifier of a. is not easy to transportation and uses for liquid; B. the manufacturing process complexity needs reacting by heating; C. this paraffin emulsifier same usage quantity when emulsified olefin is bigger, and its add-on is about 20% of paraffin add-on, and use cost is higher.

Summary of the invention

It is simple that technical problem to be solved by this invention provides a kind of manufacturing process, emulsify well, consumption is few, and only with the 4%-5% of paraffin amount, the paraffin wax emulsions that makes is nonpoisonous and tasteless, stability is strong, oilness is good, antiacid, alkali resistant, not stratified and paraffin emulsifier that use cost is lower.

For achieving the above object, technical scheme of the present invention is: a kind of paraffin emulsifier is characterized in that it forms by following component and by the feedstock production that following weight ratio is formed: lauryl alcohol 20-30 part, oxyethane 20-30 part, mono-glycerides 40-50 part, stearic acid 5-15 part, ethanol 5-15 part.

A kind of method for preparing above-mentioned paraffin emulsifier, its technological process is: at normal temperatures and pressures, in the common response still, react, at first 20-30 part lauryl alcohol and 20-30 part oxyethane are joined and carry out chemical reaction in the reactor and form the multipolymer of the two, this multipolymer is as the nonionogenic tenside of paraffin emulsifier; Add mono-glycerides 40-50 part then as nonionogenic tenside, as stearic acid 5-15 part of dispersion agent, as ethanol 5-15 part of solubilizing agent, mix, promptly can be made into the paraffin emulsifier of solid or paste.

When using this product to make paraffin wax emulsions, do not need to add again other material, only need main raw material paraffin to get final product; Through experimental results show that more than 3 years, nonpoisonous and tasteless with the paraffin wax emulsions that the production of this emulsifying agent makes, stability is strong, oilness is good, antiacid, alkali resistant, anti-hard water, not stratified, breakdown of emulsion not, and can make the emulsion of paraffin solid content more than 50%, and emulsion good water solubility, the water of arbitrary proportion dilutes not breakdown of emulsion, do not lump, not stratified, long quality-guarantee period, under 10-25 ℃ of condition, airtight, keep in Dark Place can reach more than 6-12 month and never degenerate; Can be used as industrial auxiliary agent and be widely used in fields such as weaving, papermaking, also can directly be used as releasing agent, in beaver board industry, can substitute paraffin fully as waterproof, moistureproof auxiliary agent, and paraffin is simple, cost is low than using, effective.

Embodiment

The full name of mono-glycerides is a glyceryl monostearate, molecular formula: C ₂₁H ₄₂O ₄Stearic acid, chemical name: 18 (alkane) acid, molecular formula: C ₁₈H ₃₆O ₂Lauryl alcohol has another name called lauryl alcohol, molecular formula: C ₁₂H ₂₆O; Oxyethane, ethanol is industrial chemicals commonly used.

Embodiment 1: get 20 parts lauryl alcohol, 20 parts oxyethane, 40 parts of mono-glyceridess, 5 parts stearic acid, 5 parts ethanol, in the common response still, react at normal temperatures and pressures, at first the lauryl alcohol of described component and oxyethane are joined and carry out chemical reaction in the reactor and form the multipolymer of the two, the mono-glycerides, stearic acid, the ethanol that add described component then, mix, promptly can be made into the paraffin emulsifier of solid or paste.

Embodiment 2: get 25 parts lauryl alcohol, 25 parts oxyethane, 45 parts mono-glycerides, 10 parts stearic acid, 10 parts ethanol, in the common response still, react at normal temperatures and pressures, at first the lauryl alcohol of described component and oxyethane are joined and carry out chemical reaction in the reactor and form the multipolymer of the two, the mono-glycerides, stearic acid, the ethanol that add described component then, mix, promptly can be made into the paraffin emulsifier of solid or paste.

Embodiment 3: get 30 parts lauryl alcohol, 30 parts oxyethane, 50 parts mono-glycerides, 15 parts stearic acid, 15 parts ethanol, in the common response still, react at normal temperatures and pressures, at first the lauryl alcohol of described component and oxyethane are joined and carry out chemical reaction in the reactor and form the multipolymer of the two, the mono-glycerides, stearic acid, the ethanol that add described component then, mix, promptly can be made into the paraffin emulsifier of solid or paste.

The key step that will adopt this emulsifying agent to prepare paraffin wax emulsions is described below below: with paraffin and with respect to this emulsifying agent of the about 4%-5% of paraffin add-on (weight) put people's belt stirrer reactor in stir, emulsification times remained on about 20 minutes.Add dilution water for the first time then, add about the 35%-45% of people's amount for total dilution water yield.Water temperature requires about 90 ℃, and the limit adds the waterside stirs, and the dilution water with about 65%-55% of remainder is all for the second time adding the people again, and to the water temperature no requirement (NR), normal temperature get final product, a little with stirring, just gets finished product when adding water.

This emulsifying agent is because of existing two kinds of nonionic surface active agent simultaneously; so when the preparation paraffin wax emulsions, strengthened the absorption fastness of emulsifying agent molecule on the paraffin particulate; moreover; nonionic surface active agent is to the provide protection of paraffin particulate, make the paraffin wax emulsions particle made evenly, high dispersing, shelf-stable.Particularly manufacturing of this emulsifying agent and use, normal temperature gets final product, and does not consume energy, and does not need press device, greatly reduces energy consumption, has reduced the manufacturing use cost.
