IMD glue water with good formability for automobile bumper support plate

Abstract

The invention provides IMD glue water with good formability for an automobile bumper support plate. The IMD glue water is prepared from the following ingredients in parts by weight: 15 to 25 parts of epoxy modified acrylic resin, 28 to 36 parts of carboxyl type vinisol, 6 to 14 parts of trimethylbenzene, 2 to 8 parts of tetramethylbenzene, 10 to 20 parts of cyclohexanone, 1 to 5 parts of dibasic ester, 1 to 5 parts of silicon dioxide and 10 to 15 parts of isophorone. The IMD glue water provided by the invention has no adverse influence on IMD ink, and does not contain methylbenzene, xylene, cyclohexane and the like; the IMD glue water is very safe to human bodies and environment; the IMD glue water is single liquid type evaporation drying type ink; the operation is convenient. The IMD glue water has the advantages that two kinds of resin mutually and cooperatively act in the specific range; through the matching with other ingredients, high-temperature-resistant performance, high adhesive force, high flexibility, good formability and the like are realized at the same time; the application range and the application potentiality of an IMD technology are expanded.

Description

technical field [0001] The invention belongs to the technical field of IMD, and in particular relates to an IMD glue for an automobile bumper support plate and a preparation method thereof. Background technique [0002] IMD technology belongs to the application technology of injection molding surface materials, and 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. In terms of electronic products, it was first applied to the flip cover of mobile phones by Motorola, and then developed rapidly. IMD technology is an in-mold decoration technology that can simultaneously complete injection molding of parts and surface decoration of products. It combines traditional injection molding technology with post-processing technology, integrating decoration and functionality. The process is to first print on a transparent ...

AI Technical Summary

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
