Embodiment 1

[0026] Embodiment 1: 100g chitosan is dissolved in the 2L acetic acid solution that mass percentage concentration is 5%, is placed on the magnetic stirrer, under normal temperature, stirs and degrades 4h, obtains chitosan molecule A; A is dissolved in distilled water, and a little glacial acetic acid is added dropwise, so that chitosan molecule A is dissolved in distilled water, and it is configured into a solution of chitosan molecule A with a concentration of 0.01 mg / ml, which is homogenized at 10000 rpm, freeze-dried, and obtained Chitosan microspheres: 1g of chitosan microspheres and 100g of polyurethane are cross-linked in 1.5-2% glutaraldehyde solution to obtain chitosan modified polyurethane materials.

Embodiment 2

[0027] Embodiment 2: 100g chitosan is dissolved in the 2L acetic acid solution that mass percent concentration is 8%, is placed on the magnetic stirrer, under normal temperature, stirs and degrades 5h, obtains chitosan molecule A; A is dissolved in distilled water, and a little glacial acetic acid is added dropwise, so that chitosan molecule A is dissolved in distilled water, and it is configured into a solution of chitosan molecule A with a concentration of 0.01 mg / ml, which is homogeneous at 12000 rpm, freeze-dried, and obtained Chitosan microspheres: 2g of chitosan microspheres and 100g of polyurethane are cross-linked in 1.5-2% glutaraldehyde solution to obtain chitosan modified polyurethane materials.

Embodiment 3

[0028] Embodiment 3: 100g chitosan is dissolved in the 2L acetic acid solution that mass percent concentration is 6%, is placed on the magnetic stirrer, under normal temperature, stirs and degrades 4.5h, obtains chitosan molecule A; Chitosan Molecule A is dissolved in distilled water, and a little glacial acetic acid is added dropwise, so that chitosan molecule A is dissolved in distilled water, and the chitosan molecule A solution with a concentration of 0.01mg / ml is configured, homogenized at 11000rpm, freeze-dried, Chitosan microspheres are obtained; 1.5 g of chitosan microspheres and 100 g of polyurethane are crosslinked in 1.5-2% glutaraldehyde solution to obtain chitosan modified polyurethane materials.

Abstract

The invention discloses a preparation method of a synthetic material with antibacterial properties, comprising the following steps: (1) dissolving chitosan in acetic acid solution, stirring and degrading to obtain chitosan molecule A; (2) dissolving chitosan Molecule A is dissolved in the solution, homogenized at 10000-12000rpm, freeze-dried to obtain chitosan microspheres; (3) cross-linking chitosan microspheres and polyurethane in glutaraldehyde solution to obtain chitosan microspheres Sugar-modified polyurethane material.

Description

technical field [0001] The invention relates to a polymer material and a preparation method thereof, in particular to a polymer material with antibacterial properties and a preparation method thereof. Background technique [0002] Traditional synthetic fiber fabrics only have some common properties of fiber materials, but other properties such as environmental protection, hygroscopicity, antibacterial, anti-ultraviolet, and radiation protection are very lacking. Traditional films only have the properties of ordinary films. Common performance, but such as antibacterial, environmental protection, anti-ultraviolet, transport infrared and other performance deficiencies. [0003] Chinese patent "CN201510117354" provides an antibacterial spandex fiber and its preparation method. The antibacterial spandex fiber prepared by this invention patent has stable and uniform performance, has antibacterial properties and does not have other special properties. In addition, the antibacterial...
