Problems solved by technology

Based on the injection molding conditions in the IMD process and the protection requirements for the IMD ink, the IMD glue needs to meet the characteristics of high temperature resistance, high adhesion, softness and good formability at the same time, but the existing IMD glue or other glues are difficult to meet at the same time above requirements
However, ordinary glue will have adverse effects on ink or other subsequent processes, so it is difficult to apply directly

Abstract

The invention provides a high adhesion IMD glue for roof panels. The high adhesion IMD glue is prepared from the following components by weight: 15-25 parts of a vinyl acetate-butenoic acid copolymer, 28-36 parts of carboxyl type vinyl chloride-vinyl acetate copolymer, 6-14 parts of trimethylbenzene, 2-8 parts of tetramethylbenzene, 10-20 parts of cyclohexanone, 1-5 parts of dibasic ester, 1-5 parts of silicon dioxide, and 10-15 parts of isophorone. The IMD glue provided by the invention has no adverse effect on IMD ink, does not contain toluene, xylene and cyclohexane, etc., is safe to the human body and environment, is a single-liquid type evaporation drying type ink, and is convenient for operation. Through the synergistic effect of two resin in a specific range, and under the cooperation of other components, the IMD glue provided by the invention realizes the advantages of high temperature resistance, high adhesion, high softness, good formability and the like at the same time, and expands the application scope and application potential of IMD technology.

Description

Technical field [0001] The invention belongs to the technical field of IMD, and specifically relates to an IMD glue for vehicle roof panels and a preparation method thereof. Background technique [0002] IMD technology belongs to the application technology of injection molding surface materials. It is a new type of in-mold decoration technology that combines screen printing, molding and injection molding. Introduced into China in the 1990s, it was first applied to the control panel of the home appliance industry, and the electronic product was first applied to the flip cover of the mobile phone by Motorola, and then developed rapidly. IMD technology is an in-mold decoration technology that can simultaneously complete part injection and product surface decoration. It combines traditional injection molding technology with post-processing technology to integrate decoration and functionality. The process is to first print on a transparent substrate, then shape the surface, and then ...
