Abstract

The invention provides a silica gel and cloth 3D pattern trademark label in-mold forming transfer printing process. The process includes the following steps that an environment-friendly treating agent A is adopted for coating the PET back face, and coating and roasting are performed; an environment-friendly treating agent B is adopted for coating the PET front face, and coating and roasting are performed; the environment-friendly treating agent B is adopted for coating the PET front face, and coating and roasting are further performed; a printing press is adopted for 3D color printing of printing patterns; environment-friendly glue A is printed, and roasting is conducted; environment-friendly glue B is printed, and roasting is conducted; location holes are mechanically drilled; a special lamination machine is adopted for overprinting silica gel onto a PET sheet after the step S10; silica gel oil pressure forming is carried out; vulcanization is performed; environment-friendly glue E is printed on the silica gel, hot melt glue is also printed, and drying, laser cutting and quality inspection are performed; and the 3D patterns are transferred onto a silica gel product during silica gel oil pressure forming, and the patterns can be formed on the product in times of mold stripping without deformation. The definition is high and abrasion resistance is good. Production efficiency is greatly improved, the production cycle is shortened, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of in-mold transfer printing molding of silica gel products, in particular to an in-mold forming technology of transfer printing trademarks and signs of 3D patterns on silica gel and cloth. Background technique [0002] At present, some technologies are to shape the silicone products first, and then hot stamp the pattern with a special jig heat transfer method. This method mainly has the following disadvantages: 1. The surface pattern is not clear enough. 2. The production cycle is long, and the production cost is about 30% higher. 3. The product has limitations and cannot complete the printing of 3D patterns. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide an in-mold silicone and cloth 3D pattern transfer printing trademark signage process. [0004] The technical solutions it adopts are: [0005] A process for in-mold forming of silica gel a...
