Coal briquette adhesive employing defatted soybean protein as raw material and preparation method of coal briquette adhesive

Abstract

The invention relates to a coal briquette adhesive employing defatted soybean protein as a raw material and a preparation method of the coal briquette adhesive. The coal briquette adhesive is prepared by processing the following raw materials in parts by weight: 20-30 parts of cement, 80-120 parts of modified defatted soy flour, 8-12 parts of organobentonite, 8-12 parts of propolis powder and 400-600 parts of water; the preparation method of the modified defatted soy flour comprises the steps of adding the defatted soy flour, a proper amount of compound enzyme and a proper amount of deionized water to a reaction container, adjusting the pH to 5.5-6.0, carrying out enzymolysis at 45-55 DEG C for 1-2h, heating a product to 85-95 DEG C, inactivating for 2-3min, cooling to 30-35 DEG C, adding 1-2% of a coupling agent and 0.3-0.5% of an oxidizing agent on the basis of the mass of the defatted soy flour and carrying out stirring treatment for 0.5-1h; filtering out impurities, and carrying out vacuum concentration and drying to obtain the modified defatted soy flour, wherein the compound enzyme is a mixture of cellulose, alpha-amylase and protease. The adhesive has good water resistance and bonding property; main raw materials all are natural raw materials; the coal briquette adhesive is wide in source, convenient to process and low in processing cost; the adhesive is long in expiration date; and the coal briquette processed by the coal briquette adhesive is high in quality and not easy to mildew and deliquescence caused by moisture absorption is not easily caused.

Description

technical field [0001] The invention relates to a briquette adhesive using defatted soybean protein as a raw material and a preparation method thereof. Background technique [0002] As China's main energy resource, coal will always occupy a dominant position in the short term, but environmental problems such as greenhouse effect and smog caused by its combustion products have gradually attracted people's attention, and it is necessary to vigorously develop clean coal technology. [0003] The so-called clean coal technology refers to coal gasification, liquefaction, high-efficiency coal combustion, or making anthracite coal into briquettes. As a type of clean coal, briquettes are environmentally friendly coal resources approved by the government. Among them, briquettes are sticky Mixture is the key to the preparation of briquettes, and it is also the bottleneck restricting the development of briquettes. Although the briquettes prepared by using the briquette binders on the ma...

[0003] The so-called clean coal technology refers to coal gasification, liquefaction, high-efficiency coal combustion, or making anthracite coal into briquettes. As a type of clean coal, briquettes are environmentally friendly coal resources approved by the government. Among them, briquettes are sticky Mixture is the key to the preparation of briquettes, and it is also the bottleneck restricting the development of briquettes. Although the briquettes prepared by using the briquette binders on the market can meet the requirements of industrial briquettes in terms of coldness, heat strength and thermal stability, the cost Higher, especially poor waterproof performance, only absorbing a small amount of water in the air can greatly reduce the cold strength of the briquette, which will cause a lot of damage during transportation, loading and unloading, and affect the use of the briquette
