Abstract

The invention discloses a steel slag-fiber composite rubber packing with a phase change temperature control performance and a preparation method of the steel slag-fiber composite rubber packing, and belongs to the field of recycling of solid waste resources. The composite rubber packing comprises phase change temperature control steel slag and phase change temperature control fiber. The preparation method comprises the following steps: (1) mixing a phosphoric acid solution with the steel slag to obtain modified steel slag; then mixing the modified steel slag with a phase change material, and utilizing a vacuum technology to obtain phase change temperature control steel slag; (2) mixing N,N-dimethylacetamide with a solvent, and adding cellulose acetate and the phase change material to obtain a phase change wetting fiber solution; and then utilizing electrospinning and drying means to obtain phase change wetting fiber; (3) mixing the phase change temperature control steel slag with the phase change wetting fiber to obtain steel slag-fiber composite rubber packing. The steel slag-fiber composite rubber packing provided by the invention solves the problems that the price of the main packing of the rubber industry is higher, the steel slag easily agglomerate when being directly added into rubber, and the phase change temperature control steel slag has the limited effect of improvingrubber reinforcing and phase change temperature control.

Description

technical field [0001] The invention belongs to the field of recycling of solid waste resources and the field of functional materials, and specifically relates to a steel slag-fiber composite rubber filler with phase change temperature regulation performance and a preparation method thereof. Background technique [0002] Steel slag is solid waste produced in the steelmaking process, accounting for about 15% to 20% of steelmaking output. Steel slag is mainly composed of oxides of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus, etc. The main mineral phase is a solid solution formed by tricalcium silicate, dicalcium silicate, calcium magnesium olivine, calcium aluminate ferrite and oxides of silicon, magnesium, iron, manganese and phosphorus, and also contains a small amount of free calcium oxide and metal iron etc. According to China, the steel slag produced in 2014 exceeded 120 million tons, and the steel slag produced in 2015 exceed...
