Problems solved by technology

[0003] Many of the current ultraviolet absorbers are prepared by chemical synthesis, which have certain toxicity, consume petroleum resources at the same time, and are not environmentally friendly.
In addition, the existence of alien invasive species also challenges the ecological balance. People turn them into treasures, some as feed, some as medicinal materials, and some as extracts of dyes, but they are still used as ultraviolet absorbers. No report

Embodiment 1

[0035] Dry the whole plants of A. japonicus, chrysocolla, and silver flower amaranth in an oven at 30°C for 4 hours in advance, and add the whole plants of holly chrysanthemum, stone spear, and silver amaranth at a mass ratio of 2:1:1 to the drug pulverizer. After fully pulverizing the plant, soak it in 70% ethanol water solution, and add a small amount of baking soda. The mass ratio of the whole plant of the invasive plant, ethanol water solution, and baking soda is 1:15:0.15. Mix the whole system evenly, and soak for 8 Filter after 1 hour to obtain a preliminary extract;

[0036] The primary extract obtained by filtration is subjected to dialysis separation with a dialysis membrane with a molecular weight cut-off of 5500-7000. The separation time is 2 days. The pump pressure is 0.035MPa to obtain the biomass active extract;

Abstract

The invention discloses a preparation method and an application of a biomass ultraviolet absorbent. The biomass ultraviolet absorbent comprises, by weight, 3-6 parts of biomass active extracting solution, 1.5-3 parts of dry biomass particles, 0.75-1.5 parts of natural mineral particles, 1-2 parts of biomass film-forming agents and 80-160 parts of solvents. The biomass ultraviolet absorbent is prepared from natural bio-based or raw mineral materials, achieves excellent anti-ultraviolet effects by the aid of synergistic effects of wet invasive plant active extracting solution, the dry biomass particles and the natural mineral particles, is environmentally friendly, degradable and non-irritating to organisms, can be widely applied to textiles, paper products, plastics, cosmetics and the like,and further has a certain far infrared release function.

Description

technical field [0001] The invention belongs to the technical field of finishing agents, and more specifically relates to a preparation method and application of a biomass ultraviolet absorber. Background technique [0002] Ultraviolet rays with a wavelength of 280-400nm in sunlight can reach the surface of the earth through the barrier of the atmospheric ozone layer, causing skin sunburn to appear erythema, and bringing slow changes to the elastic fibers in the blood vessel wall or connective tissue, resulting in brown skin In addition, ultraviolet rays can also cause great damage to some materials, such as rubber, paint, and synthetic fibers, so ultraviolet absorbers have become research hotspots. UV absorber is a kind of light stabilizer, which can absorb the ultraviolet part of sunlight and fluorescent light source without changing itself. [0003] Many of the current ultraviolet absorbers are prepared by chemical synthesis, which have certain toxicity, consume petroleu...
