Description
Technical field
The invention belongs to technical field of environmental management, are related to dust-proof covering material, and in particular to a kind of nanometer can give birth to completely
Object degradation liquid cover film and its application method.
Background technique
All there is the stacking of solid matter in mine, power plant, chemical plant, the ground such as smeltery and various construction sites,
The problem of necessarily leading to various fugitive dusts not only influences the beautiful and to influence the quality of air, increase the number of PM2.5 of environment
Value.
Existing dust prevention is substantially all using sprinkling water and covering strainer, although this can partially be solved the problems, such as,
There are still a variety of different drawbacks.It sprinkling water the construction site, road both sides plants trees more, all certain to preventing fugitive dust harm from having more
Effect has that water consumption is excessive although simple watering can solve this problem, watering it is more it is easy formed at
Mud influences the appearance of the city, and watering, which has been lacked, cannot effectively inhibit fugitive dust.
Second of measure is laid with strainer and causes since the non-biodegradable of strainer can not be effectively treated after to environment
Harm, there is also strainer poor adhesive forces, and the problem of being started by strong wind is easy to when blowing, and dust-proof effect is barely satisfactory, Er Qiepu
If area is big, it is laid with and its inconvenient, cost is excessively high, nor optimal measure.
Summary of the invention
Of the existing technology in order to solve the problems, such as, it is an object of that present invention to provide a kind of low in cost, preparation simplicity
Nanometer totally biodegradable liquid cover film and its application method, liquid cover film can be degradable over time
For nontoxic small molecule material, adhesive force is strong, and construction is simple is easy, and anti-dust effect is good.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of nanometer of totally biodegradable liquid cover film, formula include dendritic water soluble polymer resin,
The Nacl and calcium chloride of water soluble polymer resin quality 2.0-10%, water soluble polymer resin quality 0.02-0.5%'s
Surfactant and the scattered nano silica of water soluble polymer resin quality 0.1-1%.
Further, formula further includes the fungicide of water soluble polymer resin quality 50-150ppm.
Further, the surfactant include lauryl sodium sulfate, neopelex, glycine betaine or its
Mixture.
Further, the fungicide is quaternary ammonium salt or sodium benzoate.
Further, the dendritic water soluble polymer resin includes the macromolecule chemical combination that trihydroxylic alcohol and tertiary amine are formed
The high-molecular compound that the high-molecular compound or ternary acid and tertiary amine that object, trihydroxylic alcohol and ternary acid are formed are formed.
The application method of nanometer totally biodegradable liquid cover film, will be dissolved in water by the cover film of recipe configuration
The aqueous solution that mass percent concentration is 0.2-1.5% is made to be sprayed, the polyhydroxy of dendroid water soluble polymer resin
Structure is tridimensional network in aqueous solution, when being sprayed at solid matter surface, the shape in the surface of solids and certain depth
It at tridimensional network, is equivalent to and forms film on surface, play the effect for inhibiting fugitive dust.
Nanometer totally biodegradable liquid cover film of the invention, primary raw material are dendritic water soluble polymer trees
Rouge dissolves it in water since the structure of its polyhydroxy is a kind of tridimensional network in aqueous solution, is sprayed at solids
In matter surface, a tridimensional network is formed in the surface of solids and certain depth, is equivalent to and forms one on surface
Film plays fixed solid dust, inhibits the effect of fugitive dust.After solid matter surface sprinkling, which is covered on
The surface of solids and certain depth position, reticular structure adhesive force is strong, even if eight grades or more of wind can not form fugitive dust.
All raw materials that the present invention uses belong to green material, and totally nontoxic is harmless, during use, Neng Gou
The 8-12 middle of the month, degradable biodegrade was nontoxic small molecule material.
Dendritic water soluble polymer resin is effective to increase solubility and coagulate under the action of Nacl and calcium chloride
Solid point, thus can solve northerly wide geographic area, and winter can also construct the problem of forming a film.
It is added to compound surfactant of the concentration less than 0.05% in dendritic water soluble polymer resin, increases
The reduction and deliquescent increase of freezing point under its solubility and low temperature in water.
Dendritic water soluble polymer resin joined a certain amount of fungicide, to extend his effective life, drop
Low comprehensive use cost.
Inventive formulation each group is divided into the water-soluble substance of instant capacity, and can wait when needed and be configured to concentration is 0.2-
1.5% aqueous solution is sprayed, so that it may be played fixed solid dust, be inhibited fugitive dust.And the rainy day does not have the substance
Influence, rainwater can permeate, and the substance is environmentally protective, within the time limit of certain can complete biodegradable, do not influence subsequent
Use, construction is simple is easy, is not influenced by weather temperature.
