Abstract

The invention discloses resin-type artificial stone and a preparation method thereof. The resin-type artificial stone is prepared from the following raw materials: aggregates, filler, steel wires andbinder, wherein the aggregates are prepared by intermittently grading basalt stones; the filler adopts coal ash, quartz powder and calcium carbonate powder; the steel wire adopts the number-72 steel wire with a diameter of 0.5 mm; and the binder consists of modified epoxy resin and modified curing agent. The resin-type artificial stone produced by the invention utilizes the heat treatment procedure, so that the weaknesses of the resin-type artificial stone such as low strength, large brittleness and deformation in a high-temperature and high-humidity environment due to the internal stress canbe further eliminated. The resin-type artificial stone can be applied to a hydraulic metal structure embedded part, and a purpose of substituting the traditional hydraulic metal structure embedded part can be achieved.

Description

technical field [0001] The invention relates to hydraulic metal structure embedded parts, in particular to a resin type artificial stone and a preparation method thereof. Background technique [0002] Due to the advantages of good mechanical properties, strong bearing capacity and large industrial production, steel materials have been widely used. In water conservancy engineering facilities, there will be many other metal structures such as steel gates and structural embedded parts. Because they work in water for a long time Or run in a dry and wet environment, so it will be eroded by various water quality, gas, sun and microorganisms, and at the same time it will be rubbed by water flow, sediment and some floating objects, and the electrochemical performance of the structural material itself is not uniform , Steel generally undergoes corrosion to varying degrees. The corrosion of structural materials will reduce the load-carrying capacity of the structure, and in severe ca...
