Description

Technical Field

[0001] The invention relates to the technical field of masterbatches, and in particular to a multifunctional UV-resistant masterbatch and a preparation method thereof. Background Art

[0002] Masterbatch is a commonly used additive in plastic processing. It is a granular product made by mixing a high proportion of functional materials with carrier resins. The main function of masterbatch is to improve the performance of plastic products or give them specific characteristics, such as color, anti-aging, flame retardancy, etc. Among them, anti-UV masterbatch is an additive specially used to improve the anti-ultraviolet ability of plastic products. It is usually composed of polymer materials, ultraviolet absorbers, light stabilizers and other ingredients. After mixing with the base resin, it can absorb ultraviolet energy and convert it into heat energy for release, thereby protecting the plastic from ultraviolet damage and effectively preventing or slowing down the degradation and aging of plastics under sunlight.

[0003] At present, the production and preparation of anti-UV masterbatch generally involves directly mixing the ingredients, and then using a twin-screw extruder to melt and extrude them. The extruded melt is cooled by a water cooling or air cooling device, and then cut into the required particle shape by a pelletizer, and finally dried and packaged. The performance of the anti-UV masterbatch is tested. However, the production of this anti-UV masterbatch has the following problems:

[0004] 1. When producing UV-resistant masterbatch, it is difficult to make local adjustments to the ingredients after they are mixed. Adjustments need to be made in advance before the next batch of ingredients are mixed. The adjustment operation is cumbersome, resulting in reduced efficiency in the preparation of masterbatch.

[0005] 2. After the production of anti-UV masterbatch, part of the anti-UV masterbatch is extracted and directly tested for performance using various testing equipment. However, only the granular anti-UV masterbatch is tested, and there is a lack of testing of the basic performance of the film-like products produced from the anti-UV masterbatch. This results in poor testing of the multifunctional anti-UV masterbatch and makes it difficult to ensure the stability of the anti-UV masterbatch preparation.

[0006] In summary, there is a need for an efficient and stable method for preparing multifunctional UV-resistant masterbatch. Summary of the invention
