Abstract
The invention discloses a preparation method for a covering agent of sand for a building. Deteriorated flour serves as a film-forming agent, fine treated sand serves as a filler, and the flour and the fine treated sand are heated and mixed to form the emulsion liquid. The preparation method comprises the following steps of: 1) after crushing the fine sand, screening the fine sand by using a 1-2mm sieve to obtain fine sand powder; 2) screening the deteriorated wheat flour by using the 1-2mm sieve to obtain flour powder; 3) adding water into the flour powder, and uniformly mixing the water and the flour powder into an emulsion, and heating the mixture to the temperature of 85 to 100 DEG C to gelatinize the mixture to form the emulsion liquid, wherein the reaction time is 10 to 150 minutes; and 4) mixing and uniformly stirring the emulsion liquid and the fine sand powder to form the covering agent. The covering agent has the beneficial effect that the covering agent is sprayed onto the surface of the sand for the building to form a uniform and compact covering layer, so the sand dust for the building can be effectively prevented from floating in the environment when being stacked and transported, and the pollution of the sand dust to the environment is reduced.
Description
[technical field]
The present invention relates to the insulating covering agent processing technique field, particularly a kind of preparation method who is used for the insulating covering agent of building sand.
[background technology]
Present stage China's fundamental construction is huge, railway, highway, a large amount of building sands that use in construction site such as build a house stack, in the transportation, owing to the airborne dust of reasons such as wind-force and vehicle transport formation is one of important factor that causes environmental pollution.Development both at home and abroad at present, the insulating covering agent of producing generally adopt the organic polymer materials such as hydrocarbon polymer of pitch, vinyl chloride resin, organic oil, polyacrylonitrile, petroleum products, tensio-active agent, Ppolynuclear aromatic; The tectum that forms is difficult for degraded, causes secondary environmental pollution.
[summary of the invention]
The objective of the invention is to above-mentioned existing problems; A kind of preparation method who is used for the insulating covering agent of building sand is provided; This insulating covering agent is sprayed at the building sand surface and forms tectum uniformly densely; Float in environment in the time of can effectively preventing stacking of building sand dust and transportation, reduce pollution environment.
Technical scheme of the present invention:
A kind of preparation method who is used for the insulating covering agent of building sand is a membrane-forming agent with rotten flour, is filler with treated fine sand powder, after heating, the processing that is mixed, processes emulsion state liquid, and step is following:
1) fine sand pre-treatment: fine sand is pulverized the back cross the 1-2mm sieve, obtain the fine sand powder;
2) rotten flour pre-treatment: the wheat that will go bad was pulverized the 1-2mm sieve, obtained the flour powder;
3) above-mentioned flour powder is added the mixed evenly one-tenth of water milk sap, be heated to 85-100 ℃ and make it that gelatinization take place, reaction times 10-150min forms emulsion state liquid;
4) with above-mentioned emulsion state liquid and fine sand powder stirring and evenly mixing, can make special-purpose insulating covering agent.
The mass percent of the mixture mesometamorphism flour of said rotten flour and water is 3-12%.
The mass percent of fine sand powder is 15-30% in the said special-purpose insulating covering agent.
The method of use of this insulating covering agent: this insulating covering agent evenly is sprayed at the sand surface, forms thickness 1-3mm tectum and get final product.
Beneficial effect of the present invention:
This insulating covering agent is sprayed at the building sand surface and forms tectum uniformly densely, floats in environment in the time of can effectively preventing stacking of building sand dust and transportation, reduces the pollution to environment.
