(III) reaction of the mixture with a basic compound: after the higher fatty acid and the film-forming assistant are fully fused, adding an alkaline compound into deionized water to form a suspension, pouring the suspension into a reaction container, and reacting the suspension with the stirred higher fatty acid and the film-forming assistant for 2-3 hours at 80-90 ℃ to form mixed liquid;
(IV) reaction of the surfactant: adding a surfactant into the mixture, reacting for 2-3 hours at 85-95 ℃, and intermittently stirring once every five minutes in the reaction process to ensure that the mixture is fully fused;
(V) liquid leading-out cooling: discharging the liquid after the mixing reaction, cooling, placing the liquid into a storage box after the liquid is cooled to 35-40 ℃, standing for 50-100 hours, and modifying to obtain a finished product of the multifunctional water repellent for the mineral fiber, wherein the viscosity of the finished product is less than or equal to 300cps, the particle size range of the finished product is 20-80nm, and the weight solid content of the finished product is 10-50%;
and (VI) storage: and (4) putting the prepared water repellent finished product into a plastic barrel, sealing and storing in a cool and dry place.
3. The multifunctional water repellent for mineral fibers as claimed in claim 2, wherein: the surfactant is a nonionic surfactant or an anionic surfactant.
4. The multifunctional water repellent for mineral fibers as claimed in claim 2, wherein: the higher fatty acid in the step (one) is C12-C30 saturated or unsaturated fatty acid, such as one of lauric acid, stearic acid, triacontanoic acid or palmitic acid.
5. The multifunctional water repellent for mineral fibers as claimed in claim 2, wherein: in the step (III), the alkaline compound is one of calcium hydroxide, magnesium hydroxide or zinc hydroxide, and the weight concentration of the alkaline compound suspension is 3-15%.
6. The multifunctional water repellent for mineral fibers as claimed in claim 2, wherein: and (d) the film forming auxiliary agent in the step (II) is one of sorbitan trioleate, polyoxyethylene-polyoxypropylene block copolyether, fatty alcohol polyoxyethylene ether or sorbitan stearate alkylphenol polyoxyethylene ether.
7. The multifunctional water repellent for mineral fibers as claimed in claim 2, wherein: and (d) the surfactant in the step (IV) is one of polyoxyethylene sorbitan monostearate, alkylphenol polyoxyethylene or polyoxyethylene sorbitan monooleate.
