One-component anaerobic silicon chip bottom glue and preparation method thereof

Abstract

The invention discloses a single-component anaerobic silicon slice bottom plate adhesive, which comprises the following raw materials in parts by weight: 50-60 parts of hydroxypropyl methacrylate, 30-50 parts of polyurethane acrylate, 0.05-0.1 parts of polymerization inhibitor, and accelerator 1-2, complexing agent 0.02-0.1 and initiator 1-5; also include: methyl propylene glycol 1-3, polyethylene glycol dimethacrylate 1-3 and foaming agent 1-5. The one-component anaerobic silicon slice floor adhesive of the present invention, compared with the conventional two-component adhesive, does not require glue mixing time, and the initial curing time is about 40s. Degumming is convenient and fast, reduces manpower and material resources, greatly speeds up the production rhythm, and meets the needs of rapid and efficient industry development.

Description

technical field

[0001] The invention relates to the technical field of diamond wire cutting silicon chip adhesive in the photovoltaic industry, more specifically, the invention relates to a single-component anaerobic silicon slice bottom plate adhesive and a preparation method thereof. Background technique

[0002] Solar silicon wafer cutting is an important link in the manufacture of photovoltaic solar cells. How to improve the cutting efficiency of the cutting process and reduce unnecessary time waste is the focus of the company's attention, and the length of time for bonding auxiliary materials directly affects the work efficiency of the entire cutting process.

[0003] The traditional bonding auxiliary material uses two-component epoxy glue. Before use, the two groups of A and B need to be weighed and mixed together and stirred evenly before the glue can be applied and bonded. The bonding preparation time is long, and the initial curing time is 8 -10 minutes, it is diffi...
