Description
Technical field
The present invention relates to antibacterial moulded coal adhesive of a kind of waterproof and preparation method thereof.
Background technology
Coal in a short time will be always in occupation of leading position as the main energy resources of China, but its combustion product institute
The environmental problems such as the greenhouse effects, the haze that cause gradually cause the attention of people, it is necessary to greatly develop clean coal technology.
So-called clean coal technology is exactly coal gasification, liquefaction, the efficient burning of coal or anchracite duff is made into moulded coal etc.
Technology, moulded coal, as one kind of Filter Tuber For Clean Coal, is the environmentally friendly coal resource approved by government, wherein coal briquette bond is to prepare moulded coal
Key, be also restrict development of briquette bottleneck, though using the hot and cold intensity of moulded coal prepared by coal briquette bond in the market
And heat endurance can meet industrial shaping coal requirement, but its cost is higher, and particularly water proofing property and bacteriostasis property is poor, only inhales
The a small amount of moisture content received in air is very big with regard to that can decline the cold strength of moulded coal, can be caused in transport, cargo handling process substantial amounts of
Breakage, have impact on the use of moulded coal.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, there is provided a kind of antibacterial moulded coal adhesive of waterproof and its system
Preparation Method.
The technical solution adopted for the present invention to solve the technical problems is：
The antibacterial moulded coal adhesive of waterproof, the moulded coal adhesive is formed by the Raw material processing of following parts by weight：
20-30 parts of cement, 6-10 parts of concrete accelerator, modified 80-110 parts of defatted soy flour, 8-15 parts of organobentonite, propolis
8-20 parts of powder, 400-600 parts of water；
The preparation method of the modified defatted soy flour is as follows：Defatted soy flour, appropriate complex enzyme and appropriate are added into reaction vessel
Deionized water, adjusts pH to 5.5-6.0, in being digested at 45-55 DEG C after 1-2h, is heated to 85-95 DEG C of inactivation 2-3min, is cooled to
30-35 DEG C, defatted soy flour quality 1-2% coupling agent and 0.3-0.5% oxidant stir process 0.5-1h are added, impurity elimination is filtered
Matter, vacuum concentration, dry must be modified defatted soy flour；
The complex enzyme is the mixture of cellulase, alpha-amylase and protease.
In technical scheme, raw material has used cement, concrete accelerator, modified defatted soy flour, organic swelling
Soil and bee glue powder, contribution of each component in technical solution of the present invention are as follows：
Wherein defatted soy flour is modified, to improve the water resistance and glue performance of adhesive, moulded coal not moisture-sensitive and cause to collapse
Split, the carbohydrate in defatted soy flour contains abundant hydroxyl hydrophilic radical, make it have preferable hydrophily, influence water-fast
Performance.The crude fibre and cell wall structure in defatted soy flour are digested into by oligosaccharides using cellulase in technical scheme
Or the protein of monose, starchy material therein digests into oligosaccharide and monose by alpha-amylase, and maximum likelihood reduction is de-
Hydrophilic compounds content in fat bean powder, reduces hydroxyl quantity, strengthens its hydrophobicity.Soybean protein in defatted soy flour is big portion
Hydrophobic grouping is divided to be embedded in active group interior, hydrophilic radical exposes outside.Therefore a small amount of protease part degraded egg is added
White matter, increases its intramolecular or intermolecular group, by the exposure of its active group outside.Make to expose outside using coupling agent again
Protein active group is reacted to each other, and forms cross-linked network structure, and water resistance and glue performance are improved to realize.
Found in present inventor's practice, modified to defatted soy flour processing, its hydrophobicity is greatly improved, it may appear that
Homogeneity difference or the phenomenon of layering, therefore, attempting the appropriate organobentonite of addition, organobentonite has good thixotroping
Property, suspension stability, high-temperature stability, chemical stability, add after appropriate organobentonite stirs, you can form stable
Dispersion, improve Machinability Evaluation, that is, realize stable homogeneous.
Propolis is the viscous secretion that honeybee gathers from tree bud or bark, is described as " natural small Drug Storage ", is precious
Natural wide spectrum antibiotics, have to various bacteria, fungi, germ etc. and significantly suppress and kill effect, add appropriate honeybee
Rubber powder, using its natural broad-spectrum antiseptic bactericidal property, realizes the anti-microbial property of adhesive of the present invention, greatly prolongs its shelf-life,
Moulded coal can be avoided to go mouldy simultaneously, improve the quality of moulded coal.
The addition of cement and concrete accelerator, can accelerate the binding speed of adhesive, be molded, dry when making moulded coal
Efficiency high.
It is preferred that, 25 parts of cement, 8 parts of concrete accelerator, modified 100 parts of defatted soy flour, 10 parts of organobentonite, propolis
