Abstract

The invention discloses a heavy-load high-temperature-resistant precision grinding abrasive cloth primer and coating adhesive. The heavy-load high-temperature-resistant precision grinding abrasive cloth primer and the coating adhesive comprise an abrasive cloth base cloth, a primer and a coating adhesive. The primer and the coating adhesive are coated on the abrasive cloth base cloth. Two high-strength polymer water-soluble phenolic resins with different cross-linked network structures, silicone grease, ethylene glycol diethyl ether and organic silicon are used for modification to prepare high-strength, high-bonding-strength and high-toughness primer. Cryolite, titanium dioxide, Span, nonionic polyurethane and ethylene glycol diethyl ether are used for modifying grease to prepare the high-strength excellent-heat-resistance coating adhesive. The invention discloses a preparation method of grinding abrasive cloth primer and the coating adhesive. The preparation method comprises the stepsthat primer and coating adhesive raw materials are calculated and weighed in percentage by weight for later use; the primer is prepared; the coating adhesive is prepared; and the primer is coated onthe abrasive cloth base cloth, and the coating adhesive is coated after sand planting, so that a coated abrasive tool abrasive cloth is prepared. According to the grinding abrasive cloth primer and the coating adhesive and the preparation method, the bonding strength and toughness of a colloid base material and an abrasive material can be effectively improved, coating is uniform, and excellent heat resistance is achieved.

Description

technical field [0001] The invention belongs to the technical field of coated abrasives, and in particular relates to a heavy-duty high-temperature-resistant precision grinding emery cloth primer and cover glue and a preparation method thereof. Background technique [0002] Coated abrasives are abrasives that use adhesives to adhere abrasives to flexible substrates. Because of their high efficiency, economy, and wide range of uses, they can achieve special-shaped and curved surfaces. Adhesives, however, , The adhesive used for coated abrasives is generally made of phenolic resin or supplemented with fillers, curing agents, accelerators, surfactants and other auxiliary materials to improve the bonding strength and characteristics. However, the bonding strength of this adhesive is not high, and the bonding performance is reduced under high-speed grinding and high-temperature conditions, and the abrasive is easy to detach. Contents of the invention [0003] The present inven...
