Abstract
The invention provides a method for producing a perlite heat insulator, the perlite heat insulator is produced through expanded perlite granulation and filming process 1 and expanded perlite press forming process 2, wherein the process 1 is realized in such a way that expanded perlite is cemented into granules through plaster and sealed casings are formed at the outer surfaces of the granules; and the process 2 is realized in such a way that the produced expanded perlite granules are cemented into heat insulators by inorganic or organic adhesives. Because the expanded perlite particles are precoated to form granules and then the obtained granules are cemented into heat insulators, and the primary porous state in expanded perlite particle pores can be guaranteed without the entering of adhesives, so that the perlite heat insulator has high strength, light volume weight and good heat insulating performance. The method is suitably for producing perlite heat insulators.
Description
Technical field
What the present invention proposed is the manufacture method of the insulation material in building materials and thermal technology field, specifically method for producing pearlite insulation body.
Background technology
Expanded perlite is the heatproof heat-insulation and heat-preservation material of using always, and common and cement, waterglass are mixed and made into tabular or different form, uses as isolated heat exchange in industry and other facility.
In normal circumstances, expanded perlite is directly made the object of certain planform with adhesive bond, because expanded perlite has water imbibition, so also have the suction colloidality, often cause binding agent to be penetrated in the hole of expanded perlite, not only waste binding agent, also can cause unit weight to increase, improve thermal conductivity, reduced degree of insulation.
How making not enter binding agent and moisture in the expanded perlite hole, is the problem that needs solve and keep its intensity, raising heat insulating ability.
Summary of the invention
Have higher-strength and heat-insulating property in order to obtain expanded perlite product, the present invention proposes method for producing pearlite insulation body.This method solves the technical problem of its intensity and thermal insulation by with the prefabricated overlay film of the expanded perlite granule mode of compression moulding again.
The scheme that technical solution problem of the present invention is adopted is:
1, expanded perlite granulation coating processes: with the expanded perlite granule screening, get the particle of particle diameter more than 3mm, it is saturated to be soaked in water.Get the inclined-plane sheet material that a bottom is provided with heater and make film coated plate.To go the expanded perlite granule of excess water to spread down through immersion and drop from top, the slope dispersion of film coated plate; its particle prolongs the slope and tumbles downwards; when spreading down; be sprayed onto on the particle land plaster is reverse; the expanded perlite granule or the cluster of grains outer surface that are stained with land plaster solidify very soon; expanded perlite granule is bondd mutually; form cluster of grains; inside has cellular, forms hole between foam hole and granule, along with the following of particle rolls; be subjected to the effect of heat simultaneously; when arriving the bottom of film coated plate, granule hardens, and has finished the process of overlay film.
2, compression moulding operation: will harden and dry expanded perlite granule mixes with adhesive, curing becomes thermal insulator after the pressurization.Adhesive is suitable for inorganic or organic cementing agent.
Good effect: because the present invention is with the pre-overlay film of expanded perlite granule, form granule, again with gained the granule the bonding thermal insulator that becomes, can guarantee the original porous state in the expanded perlite granule hole, do not enter binding agent, so make it to have the intensity height, unit weight is light, heat preservation and insulation is good characteristics.Use when suiting as production pearlite insulation body.
The specific embodiment
1, expanded perlite granulation coating processes
With the expanded perlite granule screening, get the particle of particle diameter more than 3mm, it is saturated to be soaked in water.Get the inclined-plane sheet material that a bottom is provided with heater and make film coated plate.To go the expanded perlite granule of excess water to spread down through immersion and drop from top, the slope dispersion of film coated plate; its particle prolongs the slope and tumbles downwards; when spreading down; be sprayed onto on the particle land plaster is reverse; the expanded perlite granule or the cluster of grains outer surface that are stained with land plaster solidify very soon; expanded perlite granule is bondd mutually; form cluster of grains; inside has cellular, forms hole between foam hole and granule, along with the following of particle rolls; be subjected to the effect of heat simultaneously; when arriving the bottom of film coated plate, granule hardens, and has finished the process of overlay film.
Made expanded perlite granule appearance forms shell, the adhesive that can stop the use of compression moulding operation is to the granule internal penetration, and prevent owing to the infiltration of adhesive is wasted adhesive and stopped up inner hole, form hole between the porous air of isolating mutually, help the sealing heat-insulating property and the heat-insulating property of micropore.
2, compression moulding operation
The expanded perlite granule that hardens with dry is mixed with adhesive, and solidify the pressurization back, becomes thermal insulator.Can be made into sheet material, tubing and other special-shaped material, be used for the insulation engineering and use as heat-insulating material.
But used adhesive organic or inorganic adhesive.
The wherein suitable inorganic adhesive that uses is: cement, lime, magnesite binding agent or magnesium phosphate adhesive etc.
The wherein suitable organic adhesion agent that uses is: polyvinyl formal or acetaldehyde, phenolic resins, Lauxite or unsaturated polyester resin etc.
Because the expanded perlite granule is the housing state of sealing, and when the adhesive bonds, adhesive can only play cementation between housing, can not enter into an inside to go, comparatively speaking, the adhesion strength of adhesive is big, so its product strength height.Owing to make a mutual bonding by adhesive, so form the space hole again between granule and granule, formed hole has the performance that stops heat to transmit again, so thermal and insulating performance is good, while unit weight is light.
Embodiment
Filming agent adopts land plaster, and granularity is at 300 orders.At first, make it to form granule to the pre-overlay film of expanded perlite granule.
Adhesive adopts phenolic resins, press mass ratio, and adhesive and expanded perlite granule are to mix stirring at 1: 4, join then in the mould, and the demoulding afterwards of pressurizeing, drying becomes the finished product thermal insulation body.
