Acrylic foamed damping foam and preparation method thereof

Abstract

The invention discloses acrylic foaming damping foam which is applied to an OLED module and comprises a release film layer and an acrylic foam layer, the release film layer and the acrylic foam layer are overlapped together, the acrylic foam layer is formed by coating and drying acrylic foam coating liquid, and the acrylic foam coating liquid is prepared from the following components in parts by weight: an acrylic polymer, a curing agent, foamed microspheres, an inorganic filler, a dispersing agent, an inorganic pigment and an organic solvent. The acrylic foam tape prepared by the invention can absorb impact force, has excellent impact absorbability, can be widely applied to the periphery of liquid crystal as a buffer material by utilizing the characteristics, cannot cause water decomposition due to overhigh humidity, and has excellent durability.

Description

technical field

[0001] The invention belongs to the technical field of acrylic foam material preparation, and in particular relates to an acrylic foamed shock-absorbing foam and a preparation method thereof. Background technique

[0002] Due to the many advantages of OLED, OLED technology is more widely used than LCD technology, and can be extended to the fields of electronic products, commercial fields, transportation fields, industrial control fields, and medical fields. With the development of science and technology, people's life is inseparable from electronic display devices, such as mobile phones, computers, etc. These electronic devices are easy to bump and fall during use, so it is necessary to paste a layer of buffer under the screen OLED frame of these electronic devices Material foam (such as PE foam, EVA foam, PU foam) to absorb the impact of the outside world on it. Traditional foam materials are divided into PU foam, anti-static foam, conductive foam, EPE, ant...
