Abstract

The invention discloses a coating for mineral cast guide surfaces, a preparation method thereof, and a guide surface having the coating. The coating comprises, by weight, 20-35% of silicon carbide, 15-25% of silicon micro-powder, 15-25% of solid glass beads, 15-25% of epoxy resin, 0.01-0.06% of a leveling agent, 0.02-0.1% of a dispersing and anti-settling agent, 0.01-0.06% of hollow glass beads, 0.03-0.05% of a toner, 3.0-7.0% of an amine curing agent and 0.5-1.5% of a curing accelerator. A coating layer formed after coating mineral cast guide surface with the coating and carrying out compression molding increases the rigidity and the wear resistance of the mineral cast guide surface, greatly improves the planar precision of the guide surface, controls the precision to be in 10 [mu]m, and reduces the thermal deformation coefficient of the guide surface by 50% or above.

Description

technical field [0001] The invention relates to the technical field of mineral castings, in particular to a coating for mineral casting rail surfaces, a preparation method thereof and a rail surface having the same. Background technique [0002] With the vigorous development of my country's manufacturing industry, new high-tech composite mineral castings are more widely used on the base of machine tool equipment, but high-precision manufacturing has higher and higher requirements for the technical precision and material stability of machine tool equipment. Existing mineral castings generally use molds for one-time pouring and solidification at room temperature. The mounting surface of the guide rail is made of the same material as the overall casting, which often fails to meet the requirements of high-precision manufacturing in terms of precision, surface rigidity and wear resistance. [0003] The main raw materials of mineral castings are epoxy resin and natural ore. The ca...
