Additive M4228 for polymers

Abstract

The invention discloses an additive M4228 for polymers. The additive comprises 1,3,5-trimethyl-2,4,6-tri(3,5-di-tert-butyl-4-hydroxybenzyl)benzene, 3-(1,1-dimethyl ethyl)-beta-[3-(1,1-dimethyl ethyl)-4-hydroxyphenyl]-4-hydroxy-beta-methyl benzoic acid-1,2-ethylidene ester, 3,9-bis(2,4-dicumyl phenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane, DHT-4A and polyethylene wax PE 520. The additive M4228 provided in the invention can stabilize fusion indexes in the machining process of tube materials, and fusion indexes of tube materials, after addition of M4228, maintain stable before and after a plurality times of extrusion; the additive M4228 can improve the service life and aging resistance degree of the tube materials, and oxidative induction time of the tube materials after addition of M4228 is more than 80 minutes.

Description

technical field [0001] The invention relates to an additive, specifically a polymer additive M4228. Background technique [0002] Polypropylene materials produced by chemical synthesis are prone to oxidative degradation, commonly known as plastic aging. After the tube material is aged, due to the change of the molecular structure inside the material, the mechanical properties of the material are greatly reduced, and it is easy to burst when it is subjected to internal pressure. To maximize the useful life of polypropylene, additives need to be incorporated into the material. The type, amount and combination of additives have a great influence on the processing and use of materials. In the traditional pipe material extrusion process, it is necessary to add a variety of antioxidants and other additives with auxiliary functions to achieve the purpose of producing pipe materials that meet the regulations. However, these additives are often difficult to achieve satisfactory re...

Problems solved by technology

However, these additives are often difficult to achieve satisfactory results in all aspects

For example, although the processing performance is guaranteed, the service life of the material is affected due to the large consumption of some additives during the extrusion process; or because the added material is easily extracted and separated by the water flow during use, which affects human health. ; or due to the addition of additives, the production capacity of the extrusion machinery is reduced, and the unit energy consumption of the production pipe material is increased, etc.
