Problems solved by technology

[0004] At present, there is also a simple method of adding some anti-ultraviolet agents to the foaming material. Among them, bisphenol A disalicylate is the commonly used anti-ultraviolet agent. It is popular because of its low cost and easy access. When phenol A ester is applied to anti-ultraviolet rays, its absorption wavelength is only for ultraviolet rays below 350nm in the low-wavelength range, which is commonly known as short-wave and medium-wave ultraviolet rays. For long-wave ultraviolet rays exceeding 350nm, its radiation ability is actually stronger. It is more necessary to absorb effectively. How to broaden its absorption wavelength range for ultraviolet rays, so that when it is applied to foam materials, it has a long-lasting and long-lasting anti-ultraviolet function worth studying

Abstract

The invention discloses preparation and application of bisphenol A disalicyate in an anti-aging foamed material. The preparation comprises the following steps: performing reaction on ethyl salicylate and bisphenol A under the action of a catalyst of monobutyltin oxide so as to obtain a crude product of bisphenol A disalicyate, commixing the crude product with carbon black, 2,4-dyhydroxyl benzophenone and an antioxidant, further modifying with low-temperature plasma so as to obtain an ultraviolet absorbent with relatively wide absorption wavelengths, further mixing with other foamed material preparation materials, thereby obtaining the expected anti-aging foamed material. Under the synergic action of the 2,4-dyhydroxyl benzophenone with a relatively wide absorption wavelength range and the carbon black and the antioxidant, the absorption wavelengths for ultraviolet rays are effectively widened, the prepared foamed material not only has various excellent properties essential for common foamed materials, but also has good full wavelength ultraviolet resistance, and the service life the appearance attractive durability of a product made of the anti-aging foamed material are greatly prolonged.

Description

technical field [0001] The invention relates to the field of foaming material additives, in particular to the preparation of bisphenol A disalicylate and its application in anti-aging foaming materials. Background technique [0002] Foaming material refers to the foaming material that gasifies and generates bubbles inside the material to make it a porous material. It has the advantages of light weight, high specific strength, excellent insulation performance, significant cushioning capacity and strong adsorption capacity, and has been widely used. In the automotive industry, construction industry, packaging industry, agriculture, water treatment and air filtration and other fields; such as the manufacture of foam plastics, foam rubber, foam resin, etc. [0003] When foaming materials are applied to some open places, they are often exposed to sunlight and wind and rain. On the one hand, because sunlight contains a large amount of ultraviolet light that is harmful to colored o...
