Abstract
The invention discloses a biomass three-proofing finishing agent and a preparation method thereof, wherein the biomass three-proofing finishing agent is prepared from the following raw materials in parts by weight: 2-5 parts of biomass active ingredients, 0.2-1 part of biomass micro-particles, 0.01-0.1 part of natural nanoparticles, 1-3 parts of dispersing thickening agents, 0.1-1 part of pH value regulators and 25-40 parts of solvents. The biomass three-proofing finishing agent disclosed by the invention is prepared by completely adopting natural bio-based or mineral raw materials, is environment-friendly, pollution-free and fluorine-free, has obvious water and oil repellent effects, and can be used for biologically degrading residual materials after being used.
Description
Technical Field
The invention belongs to the technical field of after-finishing agents, and particularly relates to a biomass three-proofing finishing agent and a preparation method thereof.
Background
In recent years, three-proofing finishes have been the focus of research. The three-proofing finishing agent is an after-finishing agent suitable for most textile fabrics. It is prepared with nanometer organosilicon or organic fluorine as main material and through emulsification, high temperature crosslinking, etc. to provide fabric with low surface energy and high roughness and to endow fabric with excellent water and oil repellent and antifouling functions.
At present, the three-proofing finishing agent is almost all of synthetic chemical substances containing fluorine and the like, has certain biological enrichment toxicity and is not environment-friendly enough. When in use, the materials are often required to be subjected to processes such as high-temperature crosslinking and the like, and are not simple and convenient. However, a three-proofing finishing agent which is prepared by completely adopting natural raw materials such as a bio-based material and does not need high-temperature treatment does not exist, so that the development of a biomass three-proofing finishing agent which is convenient to prepare and use and has long-acting and excellent effects is urgently needed.
