Problems solved by technology

However, there will be a series of follow-up operations after the PET material is injected, and some properties of the material itself will be reduced due to the addition of flame retardants: ① Some PET materials require extremely high transparency and have a low flame retardant coefficient. Many flame retardants are colored, which makes these PET materials unable to be used on a large scale; ②PET materials are mainly used for electrical coatings after injection molding
Electrical appliances are used for various purposes, but most of them will be used with ink, but the flame retardant added in the injection molding process will destroy the adhesion of the coating and PET, causing great problems in subsequent use; ③PET in Adding flame retardants during injection molding, the flame retardants will decompose under the high temperature of injection molding, releasing environmentally unfriendly substances that cause huge pollution to the environment; and the plastic injection molding process is affected by additives, which will lead to deterioration of the performance of the final product

Abstract

The invention discloses a thermoset high-flame-retardant lusterless ink used for a PET substrate. The ink is prepared by mixing a phosphorus-nitrogen containing flame retardant, a silicone-modified polyester resin, and delustering powder with a part of diluent, performing high-speed dispersion for 20-50 min; adding a leveling agent and an antifoaming agent, and performing low-speed dispersion for 5-15 min to obtain a main agent; adding an isocyanate curing agent and the left diluent into the main agent; and performing uniform stirring to obtain the thermoset high-flame-retardant lusterless ink. The ink is good in mechanical properties, flame retardance, heat resistance and solvent resistance, is good in adhesion to the substrate and small in environmental pollution and doesn't affect the appearance of the PET substrate. The ink is reasonable in composition, good in component coordination and excellent in overall performance.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a thermosetting highly flame-retardant matte ink for PET substrates. Background technique [0002] Polyethylene terephthalate (PET) is a polymer made by the direct esterification method of polyethylene terephthalic acid and ethylene glycol or the transesterification method of polydimethyl terephthalate and ethylene glycol, commonly known as polyester, English name Polyethyleneterephthalate, referred to as PET. PET began to be mainly used for fiber and film products, and it was not used in the field of engineering plastics until 1966, when Japan's Dairen Company developed glass fiber reinforced products. At present, PET is used in half and half for fiber and plastic products; plastic products are mainly used for transparent bottles, films and sheets, and are rapidly emerging as engineering plastics. [0003] The molecule of PET is a linear polymer of highly symmetrical aromatic rin...
