Abstract

The invention provides a silica gel dot three-dimensional (3D) transfer pyrography forming method. The method comprises the following steps of: step (1). performing PET sheet back coating; step (2). performing primary coating and baking; step (3). performing PET sheet front coating; step (4). performing secondary coating and baking; step (5). performing pattern printing; step (6). performing environment-friendly glue printing; step (7). performing tertiary baking; step(8). performing positioning hole punching; step (9). performing dispensing. step (10). performing oil pressure forming; step (11). performing mold unloading; step (12). removing a PET sheet; and step (13). performing hot melt adhesive film coating. The soft and comfortable characteristics of a silica gel material are broughtinto play; a silica gel dot three-dimensional material is utilized; different 360-degree visual effects can be achieved; the sense of space is sufficient; images and texts are clear; and washing fastness and color fastness are achieved. Three-dimensional visual patterns are applied to the silica gel to achieve completely different visual effects; the planar material is subjected to the optical refraction principle; the sense of space is very sufficient; and a new product is provided for the market.

Description

technical field [0001] The invention relates to a molding technology of a silica gel mold or a decorative film, in particular to a molding method for stereoscopic 3D transfer heat transfer of silica gel dots. Background technique [0002] The existing heat transfer method cannot be directly pressed with the fabric, and the heat press will lose the effect of seeing clear pattern changes in 360 degrees, the softness is poor, and the water washes out the layer. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a silicone dot three-dimensional 3D transfer heat transfer molding method. [0004] A silicone dot three-dimensional 3D transfer heat transfer molding method, comprising the following steps: [0005] 1) Back coating of PET sheet: Take the PET sheet and apply an environmentally friendly electrostatic agent layer on the back of the PET sheet; [0006] 2) One-time coating baking: after step 1), bake in the coati...
