Abstract

The invention relates to a water-soluble nano bright grease, belonging to the technical field of preparing auxiliary paintings. The invention is characterized by that: purified softened water is adopted to replace kerosene solvent and organic solvent, ammonia water, sodium hydroxide and stearic acid are used to react with the purified softened water with a certain temperature to generate a sodium amide soap with strong emulsifying ability, paraffin and ozocerite which are solutions in high temperature are emulsified to nano particles, the sodium amide soap reacts with it self to form nano polyamide resin, the temperature drops to normal temperature, so as to obtain the water-soluble nano bright grease. The water-soluble nano bright grease can be used to fill in the nano holes of a high-molecular material to get characteristics of smooth appearance, abrasion resistance, chemical corrosion resistance and good moisture resistance, and prolong the service life of the protective paint, with the advantages of simple productive technology, non-poisonous to smell, safe and reliable usage, wide scope of application and no pollution during the using process. The water-soluble nano bright grease solves the problems that using kerosene solvent and organic solvent in the production of bright grease in prior art is easy on the environment pollution, and the raw materials of the production are so insufficient.

Description

Water-soluble nano bright grease

Technical field:

The present invention relates to a kind of water-soluble nano bright grease, belong to auxiliary coating preparation technical field.

Background technology:

After sedan limousine lacquer painting, top-grade furniture lacquer painting, high leather goods surface, aircraft and space flight equipment surface waxing glazing, can strengthen its coatingsurface glossiness and vividness, the anti-wiping that improves product is drawn, wear resisting property.To the rust-inhibiting paint that the is coated in body surface maintenance of waxing, can moistureproof, protection against corrosion, greatly extended the work-ing life of rust-inhibiting paint aspect.Traditional polishing wax product is by raw materials such as paraffin, ceresine, stearic acid, ammoniacal liquor, sodium hydroxide, under the certain water temperature condition, reaction generates the elementary mixture that the ammonia soda soap disperses, with kerosene solvent and No. 200 solvent oil dilutions, finally obtain the product of polishing wax again.Now along with the more and more attention of countries in the world to environment protection, because the volatilization meeting of kerosene solvent and organic solvent causes severe contamination to atmospheric environment, so the production and supply of these products have been stopped on world market now.Need seek new approach therefore produce the polishing wax product.

Summary of the invention:

The object of the invention is to, a kind of starting material wide material sources are provided, production technique is simple, free from environmental pollution; Solve and to adopt at present organic solvent kerosene, No. 200 solvent oils to produce polishing waxs, easily to environment, and the water-soluble nano bright grease of there is a serious shortage in the supply in starting material source problem.

The present invention realizes above-mentioned purpose by following technical solution:

A kind of water-soluble nano bright grease is characterized in that: it is made by following raw material and weight percent:

The preparation method of this water-soluble nano bright grease is as follows:

Weight percent by above-mentioned each raw material takes raw material, and the reaction process of preparation completes in 168 hours, and raw material adds at times, and addition and the step of day part raw material are as follows:

At first paraffin, ceresine are added in reactor, add 1/3 pure softening water simultaneously, reactor temperature is risen to 65～80 ℃, make paraffin and ceresine keep being the solution shape, again stearic acid is added in reactor, after the observation stearic acid dissolves, temperature of reaction kettle is down to 50 ℃, adds 1/7 sodium hydroxide simultaneously; And by this period reaction times, dividing 1/7 ammoniacal liquor 3 equivalent when inferior to add in reactor, reactor temperature remains on 50 ℃, coreaction 24 hours;

Again 2/3 pure softening water of remainder is divided into to six parts, since the 25th hour, at every turn to adding 1/6 pure softening water, 1/7 sodium hydroxide and 1/7 ammoniacal liquor in reactor, while adding 1/7 ammoniacal liquor, by dividing each reinforced interval time 3 equivalent when inferior to add in reactor, reactor temperature remains on 50 ℃ at every turn; Add altogether four times, be 24 hours the interval time at every turn added;

Since the 121st hour, then add 1/6 pure softening water, 1/7 sodium hydroxide, 1/7 ammoniacal liquor, OP-10 and TX-10 in reactor; While adding 1/7 ammoniacal liquor, by this period reaction times, divide 3 equivalent when inferior to add in reactor, reactor temperature remains on 50 ℃;

Since the 145th hour, again to adding last a 1/6 pure softening water, 1/7 sodium hydroxide and 1/7 ammoniacal liquor in reactor, add Sodium Benzoate again in reactor, while adding 1/7 ammoniacal liquor, by this period reaction times, divide 3 equivalent when inferior to add in reactor, reactor temperature remains on 50 ℃; After raw material has added, continue reaction to 168 hours in reactor, make ammoniacal liquor and stearic acid complete reaction, then temperature in the kettle is down to normal temperature, obtain the water-soluble nano bright grease product.

Principle of work of the present invention is: with pure softening water, replace organic solvent kerosene and No. 200 solvent oils fully, adopt ammoniacal liquor, sodium hydroxide and stearic acid to react with the pure softening water of certain water temperature in reactor and generate the ammonia soda soap with extremely strong emulsifying capacity, paraffin and the ceresine that will in hot temperature, be the solution shape are emulsified into nanoparticle, along with deeply carrying out of reaction, its ammonia soda soap self also reacts the polyamide resin that generates the nanometer shape, after again temperature in the kettle being down to normal temperature, obtain the water-soluble nano bright grease product.

The present invention's beneficial effect compared with prior art is:

1, this water-soluble nano bright grease adopts pure softening water to replace organic solvent and kerosene solvent, can be to environment in production link or use procedure, solve the bright cream product of existing production and used kerosene solvent and organic solvent easily environment to be caused to severe contamination, and the starting material problem that there is a serious shortage in the supply.

In can the nano level hole of filled high polymer material when 2, this water-soluble nano bright grease is used, make that its appearance is smooth, wear-resisting, resistance to chemical attack, moistureproofness is good, extends the work-ing life of protective paint, keeps the paint film vividness.

3, production technique is simple, and the nontoxic free from extraneous odour of product is safe and reliable, and applied widely.
