Problems solved by technology

However, such compounds are extremely difficult to decompose in the environment, easy to accumulate in organisms, and have health effects on the human body, while fluorocarbon-free compounds do not have the problems of being difficult to decompose and easy to produce bioaccumulation. Use will not bring adverse effects on the environment and human body
[0003] At present, the traditional water and oil repellent process will make the water and oil repellent into the form of emulsion, but there are very few reports on converting acrylate polymers into solid particles and then applying them to products. Highly transparent water and oil repellents are widely used in few on the market

Abstract

The invention discloses a fluoride-free waterproof and oil-proof agent and a preparation method thereof. The fluoride-free waterproof and oil-proof agent comprises the following components in parts bymass: 7-11 parts of fluoride-free acrylate polymer particles, 4-6 parts of biological wax, 10-14 parts of a natural adhesive component, 5-8 parts of inorganic nanoparticles, 3-5 parts of an anti-settling agent, and 106-121 parts of a solvent; According to the fluoride-free waterproof and oil-proof agent, due to the addition of the inorganic nanoparticles, the formation of a micro-nano coarse structure is enhanced, the amphiphobic performance of the waterproof and oil-proof agent is greatly improved, and the fluoride-free waterproof and oil-proof agent also has better flame-retardant and fireproof effects, can be widely applied to various products, particularly resin materials, glass products and the like, and is transparent and bright after being used; and the surface optical property ofeach material is not influenced.

Description

technical field [0001] The invention belongs to the technical field of waterproof and oil-repellent agents, and in particular relates to a fluorine-free waterproof and oil-repellent agent and a preparation method thereof. Background technique [0002] Waterproof and oil-repellent agents have become a research hotspot. Waterproof and oil-repellent agents are also called three-proof finishing agents. They are finishing agents suitable for most textile fabrics, and most of them use fluorine-containing acrylate polymers as the main active ingredients. , This kind of organic fluorine three-proof fabric finishing agent is often prepared from perfluorooctyl sulfonphthalein compound, perfluorooctanoic acid or other perfluoroalkyl compounds containing eight carbons or even longer carbon chains as raw materials to prepare organic fluorine compounds. However, such compounds are extremely difficult to decompose in the environment, easy to accumulate in organisms, and have health effects...
