Abstract
The present invention belongs to the field of chemical synthesis, and particularly relates to a paste lubricant for a needle-punched refractory fiber felt, and a preparation method thereof. The paste lubricant is prepared from the following raw materials, by mass, 20-28% of octadecyl primary amine acetate, 2-20% of glycerol, and 52-78% of a petroleum solvent. The preparation method comprises: stirring the octadecyl primary amine acetate, the glycerol and the petroleum solvent for 20-50 minutes under the heating condition with a temperature of 40-90 DEG C. The paste lubricant of the present invention has the following advantages that: the raw materials have convenient sources; the preparation is simple; the prepared paste lubricant has stable quality and uniform property; the layering phenomenon can not be generated; the settlement due to octadecyl primary amine acetate precipitation can not be generated; during storing, the paste lubricant can be semi-paste and semi-liquid along with the temperature changing while the concentrations between the paste are roughly the same, such that the quality problem of the product can not be generated during the storing; during using, a user adopts hot water to blend the paste lubricant, the taking and the using are convenient, and the product can be rapidly blended into the emulsion in the hot water.
Description
Technical field
The invention belongs to the field of chemical synthesis, be specifically related to a kind of needled fire-retardent fiber felt-rug lotion lubricant and preparation method thereof.
Background technology
In the fire-resistant fiber knit felt production technique, when the winding-up fibroblast, add the technology lubricant at its winding-up mouth.Its effect: (1) is avoided in jetting into the fiber process, and the melt-flow thigh is bonded on the spout; (2) reduce dust; (3) lubricant fiber; (4) lubricated pricker reduces the fracture of pricker and fiber etc.
Primary octadecylamine acetate is used for the needled fire-retardent fiber felt-rug technology lubricant, needing elder generation's independent purchase petroleum solvent that primary octadecylamine acetate is added thermosol during use opens, be made into 25% solution, join while hot in 70 to 90 ℃ of hot water, use after making the emulsion that contains primary octadecylamine acetate 1～1.5% concentration.Because the user uses preparation loaded down with trivial details, require to develop liquid state easy to use or lotion product always, be made into emulsion convenient directly the adding in the hot water during use.Existing ready-made liquid primary octadecylamine acetate is that stearylamine is formulated through kinds of surface promoting agent and organic acid reaction in the market, and the pasty state that is white in color is used for selecting plumbous zinc ore, carries silica, the iron ore reverse flotation.And occurred in nearly 2 years for the fluid surface lubricant that needled fire-retardent fiber felt-rug is used, but in storage, can make primary octadecylamine acetate separate out sinking, serious problems appear in quality.
Summary of the invention
The purpose of this invention is to provide a kind of needled fire-retardent fiber felt-rug lotion lubricant and preparation method thereof, this lotion steady quality, even up and down, and easy to use, directly add and dilute in the hot water and can use.
A kind of needled fire-retardent fiber felt-rug lotion lubricant of the present invention according to the mass percent meter, is made by following raw material: primary octadecylamine acetate 20～28%, glycerine 2～20% and petroleum solvent 52～78%.
Wherein, petroleum solvent is preferably used a kind of in 200# solvent oil, diesel oil or the kerosene.
The effect that the present invention adds glycerine be temperature when being down to room temperature primary octadecylamine acetate separate out unlikely caking and sink; product is uniform paste; in addition, during glycerol adding, primary octadecylamine acetate is not separated out piece and is separated with petroleum solvent; petroleum solvent is volatile; also having an effect behind the adding glycerine is because the glycerine water-absorbent is stronger, and after product surface absorbed airborne moisture content, primary octadecylamine acetate and water formed gel; can form protective layer on the surface, stop the volatilization of petroleum solvent.When the user uses, the miscible water layer that enters of G ﹠ W, primary octadecylamine acetate and petroleum solvent and hot water form emulsion.
Needled fire-retardent fiber felt-rug of the present invention is with the preparation method of lotion lubricant, and primary octadecylamine acetate, petroleum solvent and glycerine under the condition of 40～90 ℃ of heating, are stirred and got final product in 20～50 minutes.
Wherein, primary octadecylamine acetate can directly be selected the commercially available prod for use, also can be made by primary octadecylamine and acetic acid reaction, and the mol ratio of primary octadecylamine and acetic acid is 1: 1～1.1, and acetic acid is excessive response usually.When being made by primary octadecylamine and acetic acid reaction, preferably carry out according to following steps: primary octadecylamine and petroleum solvent are heated to 45～80 ℃ stop heating, treat that material all dissolves the back and adds acetic acid, add glycerine at last, under the condition of 65～90 ℃ of heating, stir and got final product in 20～50 minutes.
The invention has the advantages that: raw material sources are convenient, simple for production, the lotion lubricant steady quality that is made into is even up and down, layering can not appear, can not occur primary octadecylamine acetate yet and separate out the phenomenon that meeting is sunk, varying with temperature during storage can be aqueous for half-cream half, but the concentration between cream liquid is about the same, so product can quality problems not occur because of storage.During use, the preparation of user's heat water is taken conveniently, and product can fast modulation become emulsion in hot water.
Embodiment
The present invention will be further described below in conjunction with embodiment.
