AI Technical Summary

Problems solved by technology

When used, phenol easily enters the body, causing systemic poisoning, acute renal failure, acute liver injury and myocardial damage; nonylphenol can interfere with human endocrine, promote breast cancer cell proliferation, and cause cancer; and nonylphenol It also has the effect of simulating estrogen. Once it enters the human body, it will affect the normal reproduction and development of the human body, resulting in a decrease in the number of male sperm

Abstract

The invention relates to environment-friendly polyester polyol and a preparation method thereof. The environment-friendly polyester polyol comprises components in percentage by weight as follows: 57%-65% of adipic acid, 13%-30% of 1,4-butanediol, 12%-23% of ethylene glycol, 0.005%-0.02% of a catalyst, 0%-1.0% of a hindered phenol type antioxidant and 0%-1.0% of an environment-friendly phosphite ester antioxidant, wherein the molecular weight of environment-friendly polyester polyol is 500-4,000, preferably, the molecular weight of environment-friendly polyester polyol is 1,000-3,000. The environment-friendly polyester polyol has the advantages as follows: environment-friendly polyester polyol does not contain phenol type substances and nonylphenol, meets requirements of EU (European Union) BGA, EU EN71part 9, EU 2003 / 53 / EEC, technical requirements for environmental labeling products-leather and synthetic leather in Environmental Protection Law of the People's Republic of China (HJ 507-2009) and the like, and can be applied to solvent-free synthetic leather, water-based synthetic leather and TPU (thermoplastic polyurethane) products with high environmental requirements.

Description

technical field [0001] The invention relates to a polyester polyol, in particular to a phenol-free environment-friendly polyester polyol. Background technique [0002] At present, the "vacuum melting method" and "carrier gas melting method" are generally used in the production of polyester polyols, and both of these methods need to be reacted at high temperature, and the reaction at high temperature will easily lead to yellowing of the material. In order to protect the color of polyester polyol, some phosphite antioxidants are generally added during the production process. Phosphite antioxidants are easily hydrolyzed to form phenol or nonylphenol. When used, phenol easily enters the body, causing systemic poisoning, acute renal failure, acute liver injury and myocardial damage; nonylphenol can interfere with human endocrine, promote breast cancer cell proliferation, and cause cancer; and nonylphenol It also has the function of simulating estrogen. Once it enters the human b...
