example 1

[0026] In parts by weight, take 20 parts of thermosetting phenolic resin, 0.8 parts of curing agent, 40 parts of silicone, and 20 parts of petroleum resin in sequence, add them to the mixer, stir and mix for 45 minutes at a speed of 600r / min, and discharge , to obtain a polymer binder; cut the straw with a guillotine into short straws with a length of 5 cm, lay the short straws on the bottom of the glass tank, control the thickness of the short straws to be 5 cm, and then lay a layer of quicklime on the surface of the short straws In this way, a layer of short stalks of straw and a layer of quicklime are laid layer by layer, and then water is added to the glass jar along the wall of the glass jar until the water surface submerges the materials laid in the glass jar, and then the glass jar is sealed and left to soak and rot for 30 days. Open the glass jar, stir and mix with a glass rod for 30 minutes to obtain the modified rice straw ash; mix the rice husk with water and soak fo...

Abstract

The invention discloses a composite coal binder, and belongs to the technical field of solid fuel binders. The composite coal binder provided by the invention consists of the following raw materials in parts by weight: 30-50 parts of a polymer binder, 40-60 parts of a biomass binder and 10-30 parts of an inorganic binder, wherein the polymer binder is prepared by mixing thermosetting phenolic resin, a curing agent, organic silicon and petroleum resin; the biomass binder is prepared by mixing corn starch, carbonized rice husk, modified straw strip mixed lime mortar, humic acid and water; and the inorganic binder is prepared by mixing bauxite, kyanite and water glass. The composite coal binder provided by the invention has good bonding performance at different combustion temperatures, size stability performance of briquette coal at different combustion temperatures can be effectively guaranteed, and the briquette coal can be prevented from being disintegrated in a combustion process. Thebinder provided by the adhesive disclosed by the invention is used to solve the problem that the size stability of coal prepared by using a conventional binder is poor, and solve the problem that disintegration easily occurs in the combustion process.

Description

technical field [0001] The invention discloses a composite molded coal binder, which belongs to the technical field of solid fuel binders. Background technique [0002] Coal is an important part of primary energy. Extensive use of coal will inevitably cause a series of environmental pollution problems, which are extremely harmful to ecological balance and human existence. SO in air 2 Mainly from the combustion of coal, accounting for SO 2 More than 90% of the total source. At the same time, the backward coal development and use technology restricts the sustainable development of the national economy, and the development of clean coal technology has become an inevitable trend. [0003] Coal briquette technology is one of the clean coal technologies, and the United Nations Energy Organization promotes briquette coal as an effective way to save energy and reduce pollution. In recent years, due to the improvement of the degree of mechanization of coal mining, the proportion...
