Problems solved by technology

Existing synthetic resins mainly adopt toluenesulfonamide formaldehyde resin and benzene-containing acrylic resin or alkyd resin, which contain harmful benzene series substances and formaldehyde, so such nail polish not only smells bad, but also unhealthy for the human body. but also harmful to the environment

Abstract

The invention relates to environment-friendly saturated polyester resin and a preparation method thereof. The environment-friendly saturated polyester resin is especially suitable for processing nailpolish and belongs to the technical field of high molecular materials. The environment-friendly saturated polyester resin is prepared from the following raw materials in parts by weight: 27.4 to 37.1parts of neopentyl glycol, 2.6 to 3.6 parts of trimethylolpropane, 14.5 to 19.7 parts of adipic acid, 5.6 to 7.6 parts of m-phthalic acid, 5.6 to 7.6 parts of phthalate anhydride, 7.0 to 9.5 parts oftrimellitic anhydride, 2.1 to 2.9 parts of maleic anhydride, 0.17 to 0.25 part of triphenyl phosphite, 2.1 to 2.9 parts of n-butyl acetate and 18 to 24 parts of butyl acetate. The environment-friendlysaturated polyester resin prepared by the invention has good flexibility, glossiness, plumpness and crystalline performance and has good compatibility with nitrocellulose.

Description

technical field [0001] The invention relates to an environment-friendly saturated polyester resin and a preparation method thereof, which is especially suitable for processing nail polish and belongs to the technical field of polymer materials. Background technique [0002] Nail polish is a cosmetic widely used on fingernails or toenails. It is rich in color and has both aesthetic and protective effects. The composition of nail polish is generally composed of two types of substances, one is solid components, mainly pigments, flash substances, etc., and the other is liquid components, and liquid components can be divided into two types, one is solvent components, the other The first is a polymer solution, that is, a film-forming resin. The resin composition includes nitrocellulose and synthetic resin to increase quick-drying properties. The synthetic resins used in nail polish mainly refer to alkyd resins, toluenesulfonamide formaldehyde resins, hydroxyl-containing saturated...
