Abstract

The invention discloses an adhesive for a louver grinding disc. The adhesive is prepared by mixing a component A and a component B, wherein the component A is prepared from the following components: titanium hydroxide emulsion, sulfuric acid, compound rare earth, an organic solvent, a flame retardant, a foaming agent, pigment and filler, a rheological auxiliary agent and a dehydration catalyst; the component B is prepared from the following components: polypropylene carbonate dihydric alcohol, diisocyanate, acrylic resin, epoxy resin, a thickener, a de-foaming agent, a flatting agent, an anti-skinning agent, a curing agent and a coupling agent. The invention further designs a preparation method of the adhesive for the louver grinding disc; the preparation method provided by the invention is simple and feasible; the prepared adhesive has good flame-retarding and heat-resisting properties and has long service life.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for a louver grinding disc and a preparation method thereof. Background technique [0002] Grinding disc is a kind of grinding tool, which is generally used for grinding and polishing of objects. At present, grinding discs generally have defects such as poor impact resistance, easy to break, low grinding efficiency, high dust, and short service life. Back fleece is used in Grinding on the disc to solve the defects in its use has its broad prospects; [0003] The substance that connects two solid substances of the same type or different types is called adhesive, also known as adhesive, adhesive, or directly called glue. Adhesive is actually a raw additive. When it is in a raw state, there is no Viscosity, only when it is heated to a certain temperature on the paste line, it will become a strong adhesive. Mix the abrasive with the adhesive and then bond it to the surface of the emery clo...
