Problems solved by technology

[0002] At present, in polishing production, solid wax is usually used to polish sticky sheets, which are prepared with paraffin and rosin in a weight ratio of 2:1, and can be used after heating, melting and molding. The disadvantage is that their temperature cannot exceed At 45°C, it is difficult to clean the polishing sheet, the environment is seriously polluted, the production efficiency is low, and it is not suitable for large-scale production; and there are defects in the wax layer: adhesion points, dirt, particles, shiny points, bubbles, fish eyes, golf balls, Incomplete wax coverage, uneven or swirls; wax splashes, wax cracks, streaks or splits

Abstract

The invention discloses a liquid wax used for polishing bonding sheets as well as a preparation method thereof and the technique of the polishing bonding sheets. The liquid wax comprises the components (counted according to the weight portions of 10,000g) as follows: 662.3 to 665.7 portions of polyethylene glycols, 198.5 to 201.5 portions of paint flake, 548.7 to 551.2 portions of isopropanol, 307.0 to 309.7 portions of ammonia with a concentration of 25 percent, 2347.8 to 2353.4 portions of de-ionized water of 18 M as well as 5913.1 to 5940.8 portions of 8030 resin; each component is poured into a wax barrel according to the sequence and weight portions in turn and the mixture is slowly mixed through magnetic stirring, thus obtaining the liquid wax; the liquid wax can ensure the uniformity of the wax liquid, the consistency of viscidity as well as high polishing speed and is suitable for the production demand in batch; besides, the surface quality of a polishing sheet is good.

Description

technical field [0001] The invention relates to a liquid wax, in particular to a liquid wax for polishing and sticking a chip, a preparation method thereof and a process for polishing and sticking a chip. Background technique [0002] At present, in polishing production, solid wax is usually used to polish sticky sheets, which are prepared with paraffin and rosin in a weight ratio of 2:1, and can be used after heating, melting and molding. The disadvantage is that their temperature cannot exceed At 45°C, it is difficult to clean the polishing sheet, the environment is seriously polluted, the production efficiency is low, and it is not suitable for large-scale production; and there are defects in the wax layer: adhesion points, dirt, particles, shiny points, bubbles, fish eyes, golf balls, The wax layer is incompletely covered, uneven or vortexed; the wax liquid collapses and splashes, and the wax layer cracks, streaks or splits. Contents of the invention [0003] In order...
