Embodiment 1

[0028] A method for preparing polyvinyl chloride carbon-plastic products from coal gangue, comprising the following steps:

[0029] 1) Coal gangue pretreatment: process the coal gangue into 120-mesh coal gangue fly ash and coal gangue fibers with a fiber diameter of 0.01 mm;

[0030] 2) Coal gangue fly ash coupling and wrapping treatment: add 40 parts by weight of coal gangue fly ash and 0.4 part by weight of titanate coupling agent to the high-speed mixer, heat up to 80°C and mix for 8 minutes , the coal gangue powder ash is coupled and wrapped, then put it into the low-temperature mixer and continue to mix until it cools down to 40°C, stop the machine, and discharge the material for standby;

[0031] 3) Coal gangue fiber reinforced modification treatment: Weigh 8 parts by weight of the reinforcing agent emulsion into a beaker, add 1000 parts by weight of water, shake well, and then add 40 parts by weight of coal Gangue fibers were stirred with a glass rod to disperse them, ...

Embodiment 2

[0042] A method for preparing polyvinyl chloride carbon-plastic products from coal gangue, comprising the following steps:

[0043] 1) Coal gangue pretreatment: process the coal gangue into 200-mesh coal gangue fly ash and coal gangue fibers with a fiber diameter of 0.03 mm;

[0044] 2) Coal gangue fly ash coupling and wrapping treatment: Add 50 parts by weight of coal gangue fly ash and 0.45 parts by weight of titanate coupling agent to the high-speed mixer, heat up to 90°C and mix for 12 minutes , so that the coal gangue fly ash is coupled and wrapped, and then put it into the low-temperature mixer to continue mixing until it cools down to 45°C, stop the machine, and discharge the material for standby;

Abstract

The invention relates to a method for preparing a polyvinyl chloride carbon plastic product from coal gangue, belongs to the technical field of polyvinyl chloride carbon plastic product preparation processes, and mainly solves the technical problems of high price, high processing cost and limited resources in the prior art. According to the technical scheme, the method for preparing the polyvinyl chloride carbon plastic product from the coal gangue comprises the following steps: 1) pretreating the coal gangue; 2) coupling and wrapping the coal gangue powder ash; 3) performing coal gangue fiber reinforced modification treatment; 4) preparing a primary material of the polyvinyl chloride carbon plastic product; and 5) performing extrusion forming. The method has the advantages of green environmental protection, good water resistance, high plasticity, no harmful gas release and the like.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride carbon-plastic products preparation technology, and specifically relates to a method for preparing polyvinyl chloride carbon-plastic products by using coal gangue. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. If coal gangue is discarded, it will occupy a large area of ​​land; the escape or leaching of sulfide in coal gangue will pollute the atmosphere, farmland and water bodies; gangue hills can also spontaneously ignite and cause fires, or collapse during the rainy season, silting up rivers and causing disasters; Coal gangue amounts to more than 1 billion tons, and 100 million tons of coal gangue will be discharged every year, causing great pollution to the environment. ...
