Abstract
A preparation method of heat-insulating material includes the following steps: using one kind of three chemical raw materials of polystyrene foam, polyurethane foam and polyvinyl chloride foam as aggregate, pulverizing it into granules, mixing it with cement and water and fully stirring to obtain a mixture material, adding adjuvant, the mass ratio of mixture material and adjuvant is 250-350:0.5-1.5, and the adjuvant is formed from foaming agent, foam-stabilizer and foam-controlling agent, finally pouring and forming. The said invention possesses the advantages of light weight and good heat-insulating effect. The main performance indexes of the said invented product are as follows: folume weight 285-495 kg/m3 28d compressive strength 0.5-4.8 mpa, thermal conductivity coefficient 0.082-0.12 W/C (m.k) and freezing-thawing resistance at -15 deg.C - -20 deg.C for 25 times shows that its sample is intact.
Description
Affiliated technical field
The present invention relates to a kind of lagging material and preparation method thereof.
Background technology
The processing of industrial waste is a difficult problem of being stranded rich people always, often be difficult to handle as the polystyrene plastic foam etc. in factory or the life, generally be buried underground, but the utmost point is not easy degraded, serious environment pollution, though there are some processing methodes to handle these industry or civilian waste materials at present, its technology is complicated, and treatment effect is still not ideal enough, is difficult to satisfy the needs of productive life.And, needing a large amount of material of construction again in building trade throughout the year, the materials demand that especially has good heat preservation effect is bigger, and existing its heat insulation effect of common building material is relatively poor.
Summary of the invention
Purpose of the present invention just is to provide lagging material that a kind of technology is simple, with low cost, finished product thermal insulation is effective and preparation method thereof.
Purpose of the present invention can realize by following measure:
The present invention adopts the polystyrene plastic foam, polyurethane foam, a kind of aggregate of doing in three kinds of industrial chemicals of polyvinyl chloride foam, it is ground into particle, fully stir with cement and water again, wherein, aggregate 4%-6%, cement 30%-45%, all the other are water, stir the back and become compound, add auxiliary agent again, compound and auxiliary agent mass ratio are 250-350: 0.5-1.5, auxiliary agent is by whipping agent, suds-stabilizing agent, foam control agent is formed, and wherein, whipping agent is a rosin liquid, a kind of in aluminium powder and the lather, foam control agent is an alkaline solution, the oleic acid soap lye, a kind of in the trolamine, suds-stabilizing agent adopts the animal glue, sodium silicate, borax, a kind of in the sodium hydroxide; Wherein, three kinds of auxiliary agent ratios, whipping agent: suds-stabilizing agent: foam control agent is 0.2-0.3: 0.2-1: 0.3-0.8; Castable more at last.
Whipping agent, suds-stabilizing agent, foam control agent adopt aluminium powder, sodium silicate, alkaline solution respectively in the auxiliary agent among the present invention; Whipping agent, suds-stabilizing agent, foam control agent also can adopt rosin liquid, animal glue, oleic acid soap lye.Whipping agent, suds-stabilizing agent, foam control agent can adopt a certain or several mixing to use respectively in the auxiliary agent, can adopt sodium silicate, borax simultaneously as suds-stabilizing agent.Cement should be silicate cement, certainly, also can adopt the cement of other suitable species.
The present invention is owing to adopt above-mentioned processing method and auxiliary agent, through test of many times be: unit weight: 285-495 kilogram/rice 3 by its main performance index of product that this explained hereafter goes out, 28d ultimate compression strength 0.5-4.8mpa thermal conductivity 0.082-0.12w/ (m.k) freeze-thaw resistance-15 ℃---20 ℃ of 25 test specimens are intact, advantages such as that the present invention has is in light weight, high insulating effect, not only solved the processing of a large amount of industrial civilian waste materials such as polystyrene plastic foam preferably, reduced pollution environment; And
And utilize above-mentioned waste material to be processed into lagging material, can be used for building operation in a large number, high insulating effect not only, its weight is lighter, and thickness of wall body is thin, has reduced building cost.
