[0088] On the other hand, an embodiment of the present invention provides a method for preparing an edge-sealing material, the method is used to prepare the above-mentioned edge-sealing material, and the method includes:

[0089] According to the parts by weight of each component, water-based polyurethane resin, wetting agent, defoamer, thickener and film-forming auxiliary agent are added in sequence, and the edge sealing material is obtained after stirring and reacting.

Embodiment 1

[0093] Mix 95 parts of water-based polyurethane resin, 0.3 parts of wetting agent (product code: BYK-345), 0.5 parts of defoamer (product code: BYK-094), 0.6 parts of associative polyurethane thickener (product code: PUR- 85), and 3 parts of film-forming aid ethylene glycol butyl ether were mixed evenly to obtain the edge-sealing material prepared in this embodiment.

[0094] Wherein, waterborne polyurethane resin is prepared by the following method:

[0095] Add 25 parts of hexamethylene diisocyanate (HDI) and 700 parts of polycarbonate diol T5651 into a stirring device with a stirrer, keep warm at 90°C for 3 hours, after the reaction is completed, cool down to 50°C, and add 725 parts Acetone and 36 parts of 2,2-dimethylolpropionic acid continued to keep warm for 3 hours, then added 27 parts of acrylate isocyanate (2-IsocyanatoethylAcrylate, product code AOI-VM) for 1 hour, then added 10 parts of methanol and kept stirring for 10 hours ;

[0096] Add triethylamine, adjust t...

Embodiment 2

[0100] Mix 80 parts of water-based polyurethane resin, 0.3 parts of wetting agent (product code: BYK-345), 0.5 parts of defoamer (product code: BYK-094), 0.6 parts of associative polyurethane thickener (product code: PUR- 85), and 3 parts of film-forming aid ethylene glycol butyl ether were mixed evenly to obtain the edge-sealing material prepared in this embodiment.

[0101] Wherein, waterborne polyurethane resin is prepared by the following method:

[0102] Add 25 parts of hexamethylene diisocyanate (HDI) and 700 parts of polycarbonate diol T5651 into a stirring device with a stirrer, keep warm at 90°C for 3 hours, after the reaction is completed, cool down to 50°C, and add 725 parts Acetone and 36 parts of 2,2-dimethylolpropionic acid continued to keep warm for 3 hours, then added 27 parts of acrylate isocyanate (AOI-VM) to react for 1 hour, then added 10 parts of methanol and kept stirring for 10 hours;

[0103] Add triethylamine, adjust the pH value of the system to 7, t...

Abstract

The invention discloses an edge sealing material as well as a preparation method and application thereof, and belongs to the field of packaging materials. The edge sealing material is prepared from the following components in parts by weight: 60 to 100 parts of waterborne polyurethane resin, 0.01 to 5 parts of wetting agent, 0.01 to 5 parts of defoaming agent, 0.01 to 5 parts of thickening agent and 0.1 to 10 parts of coalescing agent. The edge sealing material provided by the invention has the characteristics of good edge sealing effect, good solvent resistance and the like, and can be applied to glass fiber cloth or textile cloth.

Description

technical field [0001] The invention relates to the field of material packaging, in particular to an edge-sealing material, a preparation method and an application thereof. Background technique [0002] Electronic-grade glass fiber is the basic raw material for electronic information, aerospace and other industries. It appears in almost every electronic component and is distributed in various fields of national economy and national defense and military industry. The electronic-grade glass fiber cloth woven by electronic-grade glass fiber is an essential basic material for copper-clad laminate (CCL) and printed circuit board (PCB) industries, and its performance largely determines the electrical properties of CCL and PCB. Important properties such as mechanical properties and dimensional stability. In the process of using electronic-grade glass fiber cloth, in order to reduce the loss of raw materials and reduce the environmental pollution caused by waste leftovers, edge-sea...
