Abstract

The invention relates to a core-shell-structured waterborne acrylate adhesive with hyperbranched polysilane as a core and a preparation method of the adhesive. According to the core-shell-structured waterborne acrylate adhesive, hyperbranched polysilane is taken as the core, and the adhesive is endowed with excellent breathability by a specific spatial three-dimensional network tree structure, larger molecular chain spacing and cavity structures among molecular chains; adhesion performance is provided by acrylate molecule segments in a shell structure of the adhesive, and water resistance is provided by silicon-containing molecule segments in a core structure. The adhesive is low in cost, excellent in breathability and water resistance, environmentally friendly and free of toxic and side effects, and can be applied to materials such as a furniture paperboard and the like.

Description

technical field [0001] The invention relates to a water-based acrylate core-shell structure adhesive with hyperbranched polysilane as the core, in particular to a water-based acrylate core-shell structure adhesive with hyperbranched polysilane as the core and a preparation method thereof. Background technique [0002] Waterborne acrylate core-shell structure sizing agents have been widely used in more and more fields, especially in the medical field, due to their environmental friendliness, non-toxicity, no VOC emissions, large molecular weight, high solid content, and low price. , as a bond between various medical products such as gauze patches, hemostatic patches, and medical patches and the human body, water-based acrylate has natural advantages. [0003] However, due to the large molecular weight of water-based acrylate, the serious entanglement of molecular chains, and the weak movement ability of molecular chains, when used as furniture cardboard adhesives, its disadva...
