Abstract

The invention provides a hot-melt pressure-sensitive adhesive for manufacturing tire label coating and a preparation method thereof, and relates to the field of hot-melt pressure-sensitive adhesives.The hot-melt pressure-sensitive adhesive for manufacturing the tire label coating is prepared from the following components in parts by mass: 32 to 45 parts of an organic polymer elastomer, 10 to 26 parts of a viscosity regulator, 10 to 30 parts of a tackifier and 0.3 to 1 part of other auxiliary agents, by selecting a plurality of high-quality organic polymer new materials which have specific functions and are produced abroad, the selection material and the proportion of the conventional hot-melt pressure-sensitive adhesive are broken through. The method is characterized in that a self-ownednew process and an equipment process parameter method are adopted. The four technical requirements that the product quality of numerous hot melt adhesive production enterprises cannot stably meet thehigh-end tire label due to high product quality requirement and high production difficulty of the hot melt pressure-sensitive adhesive for coating the high-end tire label are solved.

Description

Technical field [0001] The invention relates to the technical field of hot-melt pressure-sensitive adhesives, in particular to a hot-melt pressure-sensitive adhesive used for making tire label coating and a method for preparing the same. Background technique [0002] The hot-melt pressure-sensitive adhesive used for tire label coating is different from the hot-melt pressure-sensitive adhesive used for general label coating. The difference is that the main base material for making tires is non-polar rubber, and its labeling surface It also contains residues of dimethyl silicone oil and other pollutants. This is due to the release agent sprayed on the mold during the tire vulcanization process. Therefore, hot melt pressure sensitive adhesives are required: 1. It must have a strong initial Adhesive force and appropriate final adhesive strength; 2. It must have sufficient elastic modulus to adapt to high-speed slitting, printing, and die-cutting without overflowing glue, without stic...
