PETG blow molded bottle matte glass effect color masterbatch and preparation method thereof

Abstract

The invention discloses a PETG blow molded bottle matte glass effect color masterbatch and a preparation method thereof. The raw materials include: PETG, fluorophlogopite powder, an organosilicon light diffusing agent, white carbon black, pentaerythritol tetrastearate, an antioxidant, an ultraviolet absorbent, PMMA, a compatibilizer and a high temperature resistant solvent dye. The invention creatively introduces PMMA and the light diffusing agent into frosting masterbatch, utilizes the differences of PMMA and PETG base material density and refractive index to reach an excellent frosting effect with mica powder having a particle size of less than 10microm during processing, and can guarantee no loss of PETG base material's mechanical properties. At the same time, application of the light diffusing agent can reduce the dosage of mica, and can reach the effect of enhancing the haze while improving the light transmittance of the product. Adding of the color masterbatch provided by the invention can avoid spraying, and brings a similar matte glass effect without changing the mold procedure, thus avoiding the environmental protection problem caused by spraying.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PETG bottle blowing matte glass effect color masterbatch and a preparation method thereof. Background technique [0002] If PETG bottle blowing is used in daily chemical packaging, if a matte glass effect is required (that is, the appearance of the bottle has a glass matte effect visually to improve product quality and gain consumers' favor and increase purchase desire), it is necessary to spray matte on the blown bottle Oil secondary processing, or the original mold needs to be sand blasted (after sand blasting, if the mold needs a smooth surface, it needs to be modified). [0003] Chinese patent CN102417696A discloses a method for making a frosted bottle body, comprising the following steps: mixing mica particles and PET plastics in proportion, adding an appropriate amount of about 5% additives (antioxidant, dispersant) to improve the mica powder Fluidity, the above-mentione...

AI Technical Summary

Problems solved by technology

[0005] The above prior art adds mica powder and mica flakes to the PET base material, although it can achieve frosted or matte effects on the PET material, but it does not take into account the performance loss of the material after adding large particle size mica, and This kind of frosted or matte effect will appear rough and uneven on the surface of the product and increase the chance of product explosion in practical applications, so it cannot completely replace the existing frosted spraying technology
