Process for manufacturing thermal laminated silica gel trademark by die forming

Abstract

The invention discloses a process for manufacturing a thermal laminated silica gel trademark by die forming, which comprises the following steps of firstly, blending a TPU (thermoplastic polyurethanes) silica gel adhesive; then uniformly spraying or silk-printing the TPU silica gel adhesive on the surface of a hot melt adhesive film; next, carrying out baking; then taking out an obtained product and cooling and cutting the obtained product; scraping out the blended liquid silica gel or injecting the blended liquid silica gel into a die and laminating the die with the adhesive film product; carrying out sulfuration to obtain the thermal laminated silica gel trademark. The process provided by the invention is simple and convenient to operate and is easy to implement; the thermal laminated silica gel trademark product can be rapidly produced; a user can enable the thermal laminated silica gel trademark to be firmly laminated to a designated base material only by very simple hot-pressing laminating process; not only is the delivery cycle greatly shortened and production efficiency improved, but also transportation cost is saved and production cost is low; moreover, the thermal laminated silica gel trademark is firm to laminate, has a long service life, has no bubbles, has attractive appearance, has excellent decorating effect and product publicizing effect, can greatly promote product value so as to promote development of the related industries, such as the shoe accessory industry, the clothing industry and the jewelry industry, and is beneficial to large-area popularization and application.

Description

technical field [0001] The invention belongs to the technical field of heat-bonded silica gel trademark production, and in particular relates to a manufacturing process of mold-molded heat-bonded silica gel trademark. Background technique [0002] Silica gel (Silica gel; Silica) alias: Silicone rubber, which is a highly active adsorption material, is an amorphous substance, insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, except for strong alkali and hydrofluoric acid Does not react with any substances. Various types of silica gel form different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that other similar materials cannot replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. [0003] At present, the application of silicone products has bee...

Problems solved by technology

This method has the following disadvantages: 1. The process is complicated and the technical requirements are high, and it must be cooperated and produced by a professional manufacturer

2. Limited by the molding process, there are many defective products, which wastes fabric; 3. Because the manufacturer of the silicone trademark must obtain the fabric cut pieces to produce, and at the same time, the garment manufacturer must wait for the trademark manufacturer to return the fabric cut pieces Can only produce ready-made garments, so that the production cycle of garment enterprises is very long

4. Due to the inconvenient round-trip transportation of fabric pieces, when the trademark enterprise and the garment enterprise are far apart, not only the transportation is relatively high, but also the actual operation is almost impossible, which restricts the development of the enterprise to a certain extent
