Problems solved by technology

To improve the resistance of light stabilizers to acidic substances, we should start with reducing the alkalinity (reactivity) of hindered amine light stabilizers to prevent acidic agricultural chemicals from reacting with hindered amines to form amine salts, reduce the activity of nitrogen oxide free radicals, and cause light stability. Efficiency drops

Abstract

An efficient composite heat-resisting polyolefine light stabilizer, its production and use are disclosed. The light stabilizer consists of two or above polymerized hindered amine light stabilizer mixed components 60-95wt% and metal-ion chelate component 5-40wt%, which has hindered phenol anti-oxidant structure and bis-amide metal ion chelating structure and / or oxalamide semi-hindered amine structure. It has excellent heat and ageing resistances and can be used for PE and EVA agricultural long-life thin film or functional greenhouse thin film.

Description

technical field The invention relates to the fields of fine chemicals and polymer materials, in particular to a composite light stabilizer. Background technique The aging of polymer materials can be caused by many reasons, such as heat, ultraviolet light, mechanical stress, high-energy radiation, electric field, etc., which can be caused by a single factor or a combination of multiple factors. As a result, the molecular structure of the polymer material changes and the relative molecular weight decreases or cross-linking occurs, so that the performance of the material deteriorates, so that it cannot be used. The most common aging factors are heat and ultraviolet light, because the most exposed environment of plastics from production, storage, processing to product use is heat and sunlight (ultraviolet light). Sunlight includes ultraviolet light, visible light and infrared light. Although ultraviolet light only accounts for 6% of the energy of sunlight reaching the earth's...
