The invention discloses a phosphate tailing modified epoxy mortar surface protection material and a preparation method thereof, and relates to the technical field of constructional engineering materials.The phosphate tailing modified epoxy mortar surface protection material is prepared from a slurry component A and a solid component B, the slurry component A comprises the following components in parts by weight: 100 parts of epoxy resin, 30-40 parts of bisphenol A diglycidyl ether, 5-6 parts of a modifier, 20-60 parts of phosphate tailing powder and 10-25 parts of active carbon nanospheres; the solid component B is prepared from 10 to 15 parts of polyether amine, 10 to 15 parts of 2, 4, 6-tri (dimethylaminomethyl) phenol, 260 to 280 parts of natural sand, 60 to 80 parts of cement and 2 to 3 parts of modified silicon defoaming agent. The phosphate tailing modified epoxy mortar surface protection material has the advantages of excellent abrasion resistance, impact resistance, high medium resistance and the like, meanwhile, the price of epoxy mortar is reduced, a large amount of solid waste is consumed, and a new technical reference is provided for comprehensive utilization of the solid waste.

The mold comprises a mold body, a protection ring is arranged on the surface of the mold body, two rotating plates are fixedly connected to the bottom of the protection ring, rotating grooves are formed in the surface of the mold body, clamping grooves are formed in the rotating plates, clamping blocks are fixedly connected to the side faces of the rotating plates, and the clamping blocks are fixedly connected to the bottom of the protection ring. The rotating plate is inserted into the rotating groove, and the clamping block is embedded into the clamping groove. According to the die for flange forging, the protective ring is additionally arranged on the surface of the die body, the clamping block is installed on the side face of the rotating plate, before forging is conducted, the protective ring is installed on the surface of the die body, the rotating plate at the bottom of the protective ring is inserted into the rotating groove, and at the moment, the rotating plate is rotated, so that the clamping block is clamped into the clamping groove; when hammering forging is carried out, the surface of the die can be effectively prevented from being damaged, and the surface protection effect of the die is good.

The invention discloses a roll aluminum double-sided anodic oxidation process, which is characterized in that an anodic oxidation electrolyte is composed of sulfuric acid, aluminum ions and water, the concentration of the sulfuric acid in the electrolyte is 18% / L, the concentration of the aluminum ions in the electrolyte is 0.05% / L, and the balance is water; the process comprises the following steps: step a, coiling and aluminum surface wire drawing; step b, carrying out oil removal operation by using acidic oil removal water; c, a finished product obtained after oil removal is subjected to cleaning operation; d, the cleaned finished product is put into an electrolyte for anodic oxidation electrolysis; e, the electrolysis finished product in the step d is cleaned and blow-dried; and f, the blow-dried finished product is rolled. The process is simple, the processing efficiency is improved, the quality of the aluminum-based copper-clad plate is improved, a layer of compact and insulating oxidation film is generated on the aluminum surface, higher surface protection performance is given, the uniformity of anodic oxidation is improved, the production cost is improved, the applicability is high, and the practicability is good.

This invention discloses a thermally induced responsive self-healing superhydrophobic bamboo material and its preparation and self-healing methods. The preparation method utilizes a sol-gel method to prepare a superhydrophobic prepolymer, which is then impregnated with the bamboo material to obtain the superhydrophobic bamboo material. This invention not only assembles a superhydrophobic coating on the surface of the bamboo material through vacuum impregnation but also permeates the bamboo material with the superhydrophobic prepolymer, providing a foundation for the self-healing of the superhydrophobic bamboo material after damage. The preparation method has advantages such as simple operation, short preparation cycle, and effective improvement of the protective performance and durability of the bamboo surface. It is of great significance for improving the surface properties and functional expansion of bamboo, as well as the long-term use of durable superhydrophobic bamboo materials.
