Abstract
The invention discloses a covering agent which consists of polyvinyl alcohol and anhydrous sodium sulfate in a weight ratio of 50-100:0-50. The preparation method of the covering agent comprises the following steps: crushing polyvinyl alcohol into granules, adding anhydrous sodium sulfate and mixing uniformly to finally obtain the target product. The covering agent for waste yards is simple in components, is made of nontoxic polyvinyl alcohol and anhydrous sodium sulfate, and is easy to prepare, friendly to the environment and convenient to store; the preparation method is simple, easy to control. Before use, the covering agent is prepared into an aqueous solution with proper concentration. Therefore, the covering agent is convenient to use and can meet the use requirement of large-scale waste yards.
Description
Technical field
The present invention relates to a kind of preparation method and application of environmental purification preparation, relate in particular to a kind of insulating covering agent, preparation method and application thereof for refuse tip.
Background technology
Refuse tip is the place for heap garbage, comprises the stacking of daily life rubbish and the stacking of industrialization rubbish.As its name suggests, Environment of Rubbish Sites is poor.In order to prevent the impact on environment, conventionally adopt mulch film that the rubbish of landfill is covered, to prevent that light constituent in rubbish from, as the article such as paper, plastics bag fly away with the wind, also can prevent that mosquito from growing, and covers distributing of part stink simultaneously.But mulch film uses inconvenient, and expense is higher, while running into strong wind, also mulch film can be blown away, and does not have good covering effect.
Chinese patent (CN 101870570B) discloses a kind of soilless rubbish capping material, mainly made by the material of following weight part, 25-50 cement, 5-10 fiber, 25-50 polymer bonding agent, described fiber is mineral fibre or chemical synthetic fiber or two kinds of mixing, described polymer bonding agent is resin rubber powder, styrene-butadiene latex, in nitrile rubber at least any, or polymer bonding agent is polyacrylic ester, polyvinyl alcohol, polyvinyl formal class, at least one in vinyl acetate ethylene copolymer, or polymer bonding agent is at least one in the copolymer analog rubber powder of vinyl acetate and tertiary ethylene carbonate-VeoVa or ethene or acrylate binary or ternary, or polymer bonding agent is vibrin, furane resin, in resol at least one.Adopt the polymer composite of environmental protection to replace earthing, solve the earth not enough problem of originating; Save the operating time of earthing and alleviated operator's labour intensity.But disclosed material composition more complicated, prepares loaded down with trivial detailsly, cost is also higher.
Because the defect that above-mentioned existing refuse tip exists with insulating covering agent, practical experience and the expertise of the inventor based on being engaged in this type of product design manufacture and enriching for many years, and the utilization of cooperation scientific principle, actively research and innovation in addition, to found a kind of New-type refuse vehicle for field insulating covering agent, preparation method and application thereof make it have more practicality.Through constantly research, design, and after repeatedly studying sample and improving, finally create the present invention who has practical value.
Summary of the invention
Main purpose of the present invention is, overcome the defect that existing refuse tip insulating covering agent exists, and provide insulating covering agent, preparation method and the application thereof for field of a kind of New-type refuse vehicle, in effectively solving rubbish covering problem, preparation technology is simple, with low cost, thereby be more suitable for practicality, and there is the utility value in industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of insulating covering agent proposing according to the present invention, described insulating covering agent comprises polyvinyl alcohol and anhydrous sodium sulphate, the weight percent of described polyvinyl alcohol and anhydrous sodium sulphate is 50～100:0～50.
Prepare the method for aforesaid insulating covering agent, comprise the steps: polyvinyl alcohol to be ground into particle; Add anhydrous sodium sulphate, mix, obtain target product.
For the result of use of ensuring coverage agent, the method for aforesaid insulating covering agent, described granule of polyvinyl alcohol diameter is 100～300 orders.
Aforesaid insulating covering agent is applied to the covering of refuse tip rubbish.
The application method of aforesaid insulating covering agent, comprises the steps: described insulating covering agent to be prepared into the aqueous solution, and the described insulating covering agent aqueous solution is sprayed on to rubbish surface, and the described insulating covering agent aqueous solution solidify to form tectum.
In order to form enough firmly mulch film, the application method of aforesaid insulating covering agent, described insulating covering agent concentration of aqueous solution is 0.5%～4.0%.
By technique scheme, of the present invention for refuse tip insulating covering agent, preparation method and application thereof at least there is following advantages:
Refuse tip of the present invention is simple with insulating covering agent composition, adopts nontoxic polyvinyl alcohol and anhydrous sodium sulphate preparation, easily obtain, and environmental protection; Preparation method is simple, easily grasps, and convenient storage; Before use, only need to prepare the aqueous solution of proper concn, easy to use, can meet the service requirements of large scale rubbish field.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technique means of the present invention, and can be implemented according to the content of specification sheets, below is described in detail as follows with preferred embodiment of the present invention.

Embodiment 1
Insulating covering agent of the present invention, its components by weight percent is that the ratio of polyvinyl alcohol and anhydrous sodium sulphate is 50:50, when configuration, polyvinyl alcohol is ground into 100 object particles, then adds anhydrous sodium sulphate, mixes.When use, insulating covering agent is dissolved into 2.0% the aqueous solution, Direct Uniform is sprayed at scrap heap surface, after solidifying, can form the hard shell of one deck, can effectively prevent that scrap heap stink from distributing and the flying away of light constituent, the possibility that while also having avoided meeting strong wind, mulch film is blown away simultaneously.
Embodiment 2
Insulating covering agent of the present invention, its components by weight percent is that the ratio of polyvinyl alcohol and anhydrous sodium sulphate is 80:20, when configuration, polyvinyl alcohol is ground into 200 object particles, then adds anhydrous sodium sulphate, mixes.When use, insulating covering agent is dissolved into 1.0% the aqueous solution, Direct Uniform is sprayed at scrap heap surface, after solidifying, can form the hard shell of one deck, can effectively prevent that scrap heap stink from distributing and the flying away of light constituent, the possibility that while also having avoided meeting strong wind, mulch film is blown away simultaneously.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
