Hot stamping film for injection molding parts

Abstract

The invention discloses a hot stamping film for injection molding parts. The hot stamping film is prepared from a hot stamping base film layer, a separation layer, a color layer, an aluminized layer and an adhesive layer, wherein the separation layer is prepared from the following components in parts by weight: 40-45 parts of methyl trichlorosilane, 20-25 parts of diphenyl dichlorosilane, 6-8 parts of sodium ethylenediamine propanesulphonate, 1-4 parts of dipotassium sebacate, 5-8 parts of dioctyl sebacate, 9-13 parts of n,n'-ethylenebisoleamide and 1-2 parts of octyl and decyl glycerate; and the adhesive layer is prepared from the following components in parts by weight: 37-44 parts of thermoplastic resin, 0.4-0.6 part of sodium allylsulfonate, 1-3 parts of dibutylthiourea and 3-5 parts of hexamethyl-disilazane. According to the hot stamping film for the injection molding parts, the problemsthatthe separation effect of the separation layer in an existing hot stamping film is not significant and the aesthetic property of a product is affected by the adhesive layer are effectively solved; the hot stamping film can stably exist on the surfaces of the injection molding parts, such as installation covers of a few of water heaters, and does not easily fall off; the product can be endowed with the shiny appearance; and the quality of the product is improved.

Description

technical field [0001] The invention belongs to the field of hot stamping of injection molded parts, and in particular relates to a hot stamping film for injection molded parts. Background technique [0002] The so-called hot stamping is to use a certain pressure and temperature to use the template installed on the hot stamping machine to make the printed matter, hot stamping film and hot stamping plate be pressed together in a short time, and the electrochemical aluminum foil or color pigment foil on the hot stamping film is pressed against the hot stamping template. The graphics and texts require the processing technology to be transferred to the surface of the material to be ironed. From the process, it can be divided into hot stamping first and then stamping and stamping first and then stamping. Hot stamping first is to hot stamp the electrochemical aluminum foil layer on the blank substrate first, and then print graphics and texts on the surface of the aluminum foil la...

AI Technical Summary

Problems solved by technology

From the perspective of the base film, due to the differences in the equipment conditions, process level and raw material selection of domestic film factories, the quality of the hot stamping base film on the market is uneven, and most of the products have mediocre performance, and the release layer performance of the hot stamping film is relatively poor. Poor, during the bronzing process, the ingredients in the bronzing film cannot be completely separated from the base film, and the adhesive layer will seriously affect the aesthetics of the pattern
