Problems solved by technology

[0007] However, the repelling effect achieved by internal addition cannot be reflected between the fibers of the fiber product, and water and oil can still pass through the gaps between the fibers of the fiber product, so the barrier effect is poor and needs to be improved
[0008] It is a better way to realize the physical structure repelling and barrier effect by uniformly coating the surface of the polymer product with inorganic micro-nano materials, but the prepared structure is generally easy to fall off, and the barrier effect is obviously reduced, so it is necessary to have a more stable A method of immobilizing micro-nano inorganic particles, thereby further promoting the application in repellent barrier products

Embodiment 1

[0058] A polymer product with a repellent structure and a preparation method thereof, specifically comprising the following steps:

[0059] A. Prepare 200g of heptadecafluorodecyl methyl trimethacrylate and 9.8kg of isopropanol into a solution with a concentration of 2%, weigh 2kg of fumed silicon, slowly add the solution into the fumed silicon, and stir rapidly for 2 hours, the temperature is controlled at 50°C.

[0060] Then it was centrifuged at high speed and filtered, stirred and dried at 95° C. for 2 hours, cooled and ground to obtain the fluorine compound-coated gas-phase silicon nanometer material.

[0061] B. Treat the gas-phase silicon nanomaterials coated with fluorine compounds at 20KV high-voltage electrostatic treatment for 5 minutes

[0062] C. Add the prepared coated nanomaterials into polypropylene particles in a mass ratio of 0.5%, mix evenly, and mix and extrude through twin-screw at 210° C. to obtain mixed plastic particles.

[0063] D. Melt-spinning the ...

Embodiment 2

[0066] A polymer product with a repellent structure and its preparation method. This embodiment is a variation example of Embodiment 1. The difference from Embodiment 1 is that in step C, the mixed plastic particles are melt-blown to obtain a melt-blown non-woven fabric. The water and oil repellent product was obtained through post-processing, and the rest of the steps and conditions were the same as in Example 1.

Embodiment 3

[0068] A polymer product with a repellent structure and its preparation method. This embodiment is a modification of Embodiment 2. The difference from Embodiment 2 is that a heat treatment step is included after step D. The heat treatment step specifically includes the following steps : The melt-blown nonwoven fabric prepared in Example 2 was treated in an oven at 50° C. for 2 hours, and a water- and oil-repellent product was obtained through post-processing. The remaining steps and conditions were the same as in Example 2.

Abstract

The invention discloses a polymer fiber product with a rejection barrier structure and a preparation method of the polymer fiber product, and belongs to the technical field of polymer materials. The polymer fiber product comprises a polymer material body and an inorganic micro-nano material which is distributed on the surface of the polymer material body in a concave-convex shape and has a coatingstructure, wherein the inorganic micro-nano material with the coating structure comprises a coating agent and an inorganic micro-nano material; and part of the polymer product further comprises a migration auxiliary agent. The preparation method comprises the following steps: A, mixing and dispersing the inorganic micro-nano material and the coating agent, carrying out centrifuging, washing and drying; B, carrying out electrostatic treatment; C, mixing the polymer material body with the migration auxiliary agent to obtain mixed plastic particles; D, carrying out forming processing heat treatment on the mixed plastic particles; and E, carrying out electret charged treatment to obtain the polymer fiber product. The polymer fiber product obtained by the invention has an outstanding rejectioneffect on oil and water and a permeation barrier capability, and the application range of a basic product can be expanded.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polymer fiber product with a repelling and barrier structure and a preparation method thereof, in particular to a novel polymer fiber product with a repelling and barrier structure and a preparation method thereof. Background technique [0002] Polymer material products are widely used in daily life. They have obvious water-repellent properties, so they have a good application in water packaging. However, polymer fiber materials have a high specific surface area and a considerable degree of water affinity. It is easy to penetrate fiber products, and its barrier property is poor. The molecular structure of polymer materials determines that it has a certain affinity for oily substances. Oil-stained polymer products are more difficult to clean up. The oil will penetrate through the packaging after being packaged with polymer materials or exposed to oily subst...
