Usage

General Description

2-hydroxyethyl 2-hydroxyethyl-carbamate, also known as HEHEC, is a chemical compound commonly used in personal care products and industrial applications as a preservative and antimicrobial agent. It is a colorless, odorless liquid with a slightly sweet taste and is soluble in water. HEHEC is effective in inhibiting the growth of various microorganisms, including bacteria, yeast, and mold, making it a valuable ingredient in products such as shampoos, lotions, and household cleaners. However, there have been concerns about the potential health risks associated with HEHEC, including skin irritation and allergic reactions, prompting some companies to seek alternative preservatives for their products.

Environment-friendly polyurethane chain extender as well as preparation method and application thereof

The invention relates to an environment-friendly polyurethane chain extender as well as a preparation method and application thereof, and belongs to the technical field of chemical materials. The compound is represented by the following formula I, wherein R1 is a straight chain or branched chain alkyl group consisting of C1-C6; and R2 is a straight chain or branched chain alkyl group consisting ofC1-C6. The environment-friendly polyurethane chain extender disclosed by the invention is applied to the preparation of a two-component polyurethane coating or adhesive. The environment-friendly chain extender has the beneficial effects that (1) the environment-friendly chain extender is a dibasic alcohol polyurethane chain extender containing carbamate, and the structure of the chain extender does not contain any aromatic group, so that the toxicity of the chain extender is greatly reduced; (2) relatively long operation time of the chain extender and the polyurethane material after mixing isensured; (3) the chain extender is high in strength and good in weather resistance after being cured, so that the performance of a polyurethane product can be improved, the application of the polyurethane product is enriched, and the diversified requirements of people on a polyurethane material are met.
