Problems solved by technology

However, due to the single performance of various emulsions, there are relatively large defects in balancing the peel strength, water resistance and thermal grinding resistance of the coating adhesive layer, and it is difficult to fully meet the needs of terminal applications. Highly polar compounds, in the process of being used together with emulsions, often have poor miscibility due to large differences in polarity, which greatly reduces the applicability of the product

Abstract

The invention discloses a special coated abrasives adhesive preparation and a preparation process thereof; the special coated abrasives adhesive preparation is prepared from, by weight, 30-35% of styrene, 30-35% of butyl acrylate, 10-15% of methyl methacrylate, 5-10% of acrylonitrile, 3-5% of paraffin, 3-5% of urea, 2-5% of glyoxal, 1-2% of a plasticizer, 1-2% of an emulsifier, and 1-2% of silane coupling agent. By introducing various functional monomers through process and formula innovations, adhesive strength and wet adhesive strength of emulsion are improved effectively, the polarity of the product is improved effectively, the properties of the product are improved, and the phenol-aldehyde mixing solubility of the product is also improved.

Description

technical field [0001] The invention relates to a special adhesive for coating abrasive tools, in particular to a high-strength adhesive with good phenol formaldehyde compatibility and a preparation process thereof. Background technique [0002] The traditional emery cloth coating and bonding technology usually uses various synthetic emulsions, such as styrene-butadiene emulsion, acrylic emulsion, nitrile emulsion, etc., and is used in combination with phenolic resin. However, due to the single performance of various emulsions, there are relatively large defects in balancing the peel strength, water resistance and thermal grinding resistance of the coating adhesive layer, and it is difficult to fully meet the needs of terminal applications. Highly polar compounds, in the process of being used together with emulsions, often have poor miscibility due to large differences in polarity, which greatly reduces the applicability of the product. [0003] For the application requirem...
