Description

Technical Field

[0001] The invention relates to the technical field of organic materials, and in particular to a polymer material feeling agent and a preparation method thereof. Background Art

[0002] Polymer materials are increasingly becoming one of the indispensable materials in daily life. Polymer products that come into contact with human skin feel uncomfortable due to the high hardness of polymer materials. In order to improve the comfort of plastic, a feel agent is generally added to polymer products. The feel agent is a chemical agent with a soft texture, good toughness and scratch resistance, which can make the surface of the product have an excellent touch. When combined with resin or leveling agent, it will have an extremely smooth and silky feel, improve the stickiness and excessive softness of the paint surface, and can also create a sand texture or frosted feel. The feel agent generally refers to lubricating substances such as silicones with low surface energy, such as polysiloxanes, and fluorines such as polytetrafluoroethylene.

[0003] The patent (patent number CN116376295A) discloses a reactive feel agent, which includes bihydroxyl silicone oil, oleic acid amide and erucic acid amide. By using bihydroxyl silicone oil to introduce polysiloxane segments into the polyurethane molecular structure through chemical bonds, and compounding a small amount of oleic acid amide and erucic acid amide, it can provide an ideal comprehensive feel without affecting the reactivity of bihydroxyl silicone oil, that is, elastic, plump, soft and baby-like touch effects. The patent (patent number CN116715855B) discloses an oleophobic skin feel agent and a preparation method thereof. The feel agent is obtained by three-dimensional cross-linking of perfluoro units, silicone units and polyether units. The end of the skin feel feel agent has a hydrophilic polyether unit, which can increase the solubility of the feel agent. At the same time, it also has a perfluoro unit, which further reduces the surface tension, and can make the feel agent more oleophobic, so that it can completely not absorb oil, so that the surface will not become sticky due to oil absorption under long-term use, and the durability of the smooth feel of the fabric is improved. The patent (patent number CN104927057B) discloses a new aminophenyl modified silicone oil, which can be used as a hand feeling agent. It has the characteristics of anti-fouling, quick drying, fluffy hand feeling, good stability, etc., which is more suitable for market needs. These hand feeling agents have great problems in compatibility, dispersibility, heat resistance, etc. with polymer materials such as plastics, rubber and chemical fibers. Summary of the invention
