specific Embodiment approach 1

[0020] Specific embodiment 1: A method of micro-nano fiber reinforced paraffin in this embodiment includes the following steps:

[0021] One, paraffin, emulsifier and emulsification aid are mixed homogeneously under the condition that temperature is 80~90 ℃ and stirring speed is 600rpm~900rpm, obtain mixed liquor; Wherein the mass ratio of paraffin and emulsifier is 10:( 3.5~4); The mass ratio of described paraffin and emulsifying aid is 10: (0.4~0.8); Described emulsifying agent is the emulsifying agent of HLB value 8~18; Described emulsifying aid is n-butyl alcohol, isoamyl alcohol or stearic acid;

[0022] 2. Add the mixed solution at a temperature of 80 to 90°C and a stirring speed of 600rpm to 900rpm, add water at a temperature of 80 to 90°C at a rate of 50mL / min to 80mL / min, and continue stirring at room temperature. The stirring speed is 600rpm~900rpm, stirring for 10min~15min, and the paraffin wax emulsion is obtained after cooling; wherein the mass ratio of the mixed...

specific Embodiment approach 2

[0026] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the paraffin wax described in step one is 58# paraffin; the emulsifier described in step one is Tween60, Span-80, Tween-80, polyoxygen Ethylene monostearate, polyoxyethylene monooleate, OP-10, alkylaryl sulfonate, NP-7, NP-9, stearic acid, or triethanolamine. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0027] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the mass ratio of paraffin described in step one and emulsifier is 10: 3.7; The mass ratio of paraffin described in step one and emulsifying aid The ratio is 10:0.7. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to a method for reinforcing paraffin, and concretely relates to a method for reinforcing paraffin through micro-nano fibers to solve the problems of low strength, no toughness, complex preparation method, long preparation time and high preparation temperature of present paraffin. The method comprises the following steps: uniformly mixing paraffin, an emulsifier and an emulsification aid, adding water, stirring, adding the micro-nano fibers a suspension of the micro-nano fibers, mixing through a high mixing machine, and drying in a culture dish to obtain a paraffin / micro-nano fiber film. In the invention, the reaction temperature is low to 80-90DEG C, and the energy consumption is less, so water bath heating can be directly used; the micro-nano fibers can be added at room temperature and can be directly stirred, so the operations are simple and are easy to implement; and the reaction is carried out for about 50min, so the consumed is short. The method can be used in the chemical engineering field.

Description

technical field [0001] The present invention relates to a method of strengthening paraffin. Background technique [0002] In the construction industry, agriculture, wood processing and other industries, paraffin wax is often used in the form of film, but paraffin wax has low hardness and strength, brittle texture, no ductility, and is easy to break and fall off, which limits automatic mechanical operation and low labor productivity. [0003] Paraffin wax emulsion is a waxy and water-containing homogeneous fluid made by physical modification of various waxes including petroleum wax. It has anti-acid, anti-alkali, hard water resistance, strong water solubility, and stable emulsion. Layering, no demulsification, no caking, long shelf life, high solid content, good dispersibility, etc. With the introduction and implementation of the new concept of "green chemistry", the development and utilization of paraffin wax emulsion has attracted more and more attention. Using water inste...
