Embodiment 1

[0018] The mica powder is modified mica powder, and the specific modification method is as follows: 1) Weigh the raw mica powder according to the following mass ratio: acetone:lauroyl peroxide:acrylic acid=2:3:1.5:4, and the mica The powder was added into acetone, and after adding the lauroyl peroxide and the acrylic acid under stirring, ultrasonically dispersed for 15 minutes, reacted at 65 °C for 1 hour, filtered the product obtained from the reaction, and dried in a 90 °C oven for 4 hours to obtain acrylic acid. Surface-modified mica powder A; 3) adding mica powder A and polyethylene wax into an extruder according to the mass ratio of mica powder A: polyethylene wax=12:7, and extruding and granulating to obtain a modified mica powder. .

[0019] S1: successively add 4 parts of nano-silica, 2 parts of mica powder, 0.4 parts of nano-silver, and 20 parts of benzophenone to the methacrylate copolymer solution, and ultrasonically disperse and stir to obtain solution A;

Abstract

A method for preparing a strong non-woven fabric for packaging, comprising the following steps: S1: preparing a soaking solution; S2: extruding a mixture of fine fiber polymer and binder fiber from a large screw at high temperature, and the heating temperature is 260-280 °C, polymer B in molten state is obtained, polymer B is sprayed through an extruder at a pressure of 4.8-5.3 MPa, stretched through a stretcher to form a fiber drawing C, and guide it into solution A Soak for 4 to 8 hours, and then lead to the web forming machine; S3: When three or four layers of fiber drawing material B are laminated on the web forming machine, guide the laminated material to pass through the ultraviolet irradiation area for 15 minutes, and then guide it to the hot rolling mill for hot rolling , During hot rolling, resin powder is evenly sprayed on the surface of the fiber drawing object, and the hot rolling conditions are 160-180 ° C, 4 MPa to obtain non-woven fabrics, which can be wound and formed. Good load-bearing effect, high toughness, and bactericidal ability.

Description

technical field [0001] The invention relates to the field of non-woven fabric preparation, in particular to a preparation method of a strong and tough non-woven fabric for packaging. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through air flow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally after finishing Formed non-woven fabric. A new type of fiber product with a soft, breathable and flat structure, the advantage is that it does not produce lint, it is strong, durable, and silky soft, and it is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven Cloth bags are easy to form and inexpensive to manufacture. [0003] Non-woven fabrics are widely used in the field of packaging, but the current non-woven packaging is not very strong and has limited loa...
