Problems solved by technology

The reflective decorative sheet adopts the existing technical scheme, which not only has complicated process and strict operating conditions, but also requires high precision equipment
The reflective decorative sheet manufactured by the prior art scheme has the following disadvantages: 1. Strong activity and strong adsorption capacity. When used in clothing, etc., the color on the fabric will be absorbed, causing the trademark pattern and label to cross colors; 2. Hand feeling It is hard and not soft enough; 3. It can only withstand the washing temperature of 40-60 ° C, and cannot meet the industrial washing requirements of some special brands for trademarks and labels (washing at 90 ° C for more than 20 times, and each washing time is 90 minutes); 4. In the aging test (the oven temperature is 80°C, the humidity is 75°C, and the time is 72 hours), cracks will appear on the surface; 5. It is increasingly unable to meet the increasingly high environmental protection requirements for materials

Abstract

The invention relates to the technical field of decoration sheet manufacturing, and especially relates to a reflective silica gel decoration sheet and a preparation method thereof. The reflective silica gel decoration sheet sequentially includes a PET protective film, a reflective layer, a silica gel base layer, a silica gel bonding layer and a hot-melt adhesive film from bottom to top, and the reflective layer includes, by weight, 10-15 parts of reflective powder, 60-80 parts of silica gel and 3-5 parts of a diluent; the silica gel base layer includes, by weight, 4-6 parts of the silica gel and 3-5 parts of the diluent; and the silica gel bonding layer includes, by weight, 29-43 parts of the silica gel and 3-5 parts of the diluent. The reflective silica gel decoration sheet of the presentinvention is simple to make, and has the characteristics of cross color resistance, soft touch feeling, washing resistance, aging resistance and environmental protection.

Description

Technical field: [0001] The invention relates to the technical field of decorative sheet manufacturing, in particular to a reflective silica gel decorative sheet and a preparation method thereof. Background technique: [0002] Decorative sheet refers to resin (or direct polymerization of monomers during processing) as the main component, with plasticizers, fillers, lubricants, colorants and other additives as auxiliary components, which can be flow-formed during processing. Material. Decorative sheets are widely used in trademark patterns and labels of various clothing, bags, shoes and hats, sports equipment, etc. [0003] The technical solution of the reflective decorative sheet used in various clothing, bags, shoes and hats, sports equipment and other trademark patterns and labels is to use polyurethane resin glue to bond the reflective powder, PET protective film, and hot melt adhesive of the reflective decorative sheet. membrane and other components. The reflective de...
