Abstract

The invention relates to an adsorption pad for STN glass polishing. The adsorption pad is sequentially provided with release paper, double faced adhesive tape, a PET film, double faced adhesive tape, a fluorinated polyurethane porous film and a protection film from bottom to top. A surface adsorption layer, a first foaming layer, a second foaming layer, a third isolating layer and a fourth foaming layer are sequentially arranged on the fluorinated polyurethane porous film from top to bottom, and the surface adsorption layer is a compact layer. The first foaming layer and the second foaming layer are each of a drop-shaped porous structure, the fourth foaming layer is of an oval porous structure with the average pore size ranging from 200 micrometers to 400 micrometers, and the third isolating layer is of a net-shaped pore structure formed by round micrometer pores with the pore size ranging from 2 micrometers to 20 micrometers. The adsorption pad for STN glass polishing has high hydrophobicity, permeation of polishing liquid can be slowed down, heat generated by friction of a polishing disc can be dissipated well, and the service life of the grinding adsorption pad reaches 72 h to 75 h and is prolonged by 20 h to 30 h compared with an adsorption pad, prepared from previous known polyurethane resin compositions, for STN glass polishing.

Description

technical field [0001] The invention belongs to the technical field of polymer materials and their preparation, and in particular relates to an adsorption pad for STN glass polishing. Background technique [0002] With the advancement of technology and the improvement of product quality, the demand for STN continues to increase. In the process of STN glass production, product quality, output and cost are the key to the survival of the enterprise. To ensure these three factors, it is necessary to have the support of a complete polishing process. Therefore, the quality of the STN glass polishing process determines the quality of the STN glass. During the polishing process of the STN glass, the STN glass needs to be placed There are three types of adsorption pads currently used in China on the polishing pad to polish the STN glass; 1. Cerium oxide pad, 2. Polishing felt, and 3. Polishing cloth. The adsorption pads produced in the prior art can realize the grinding of STN glas...
