Abstract

The present invention provides coating materials (14), insulation-containing building material products bearing the materials and methods for applying the coatings to the building material products. The coating materials possess one-way 'breathability' characteristics with respect to water and aqueous solutions. That is, the coatings are essentially impermeable to liquid water and permeable to water vapor. Vapor from water insulation coated by the material may thus pass through the coating, whereas liquid water is effectively prevented from passing through the coating and entering the insulation.

Description

Semipermeable coating for building material
Invention field
The present invention relates to a kind of plastics products for building in general, and specifically, relates to a kind of construction material coating, has the goods of this kind coating and the coating composition method to the construction material.
Background of invention
Pipeline and conduit are to be used in building and heating, heating ventilation and air-conditioning (HVAC) system to carry air.In many application, particularly in the commercial and industrial building, pipeline is with heat insulation and sound insulating material liner.This liner has improved the thermal efficiency of pipe element and has reduced the noise that produces when air therefrom flows.Pipe lining (duct liner) can comprise any suitable organic material or inorganic material, for example mineral fibres insulation such as glass fibre etc.Typical fiber glass duct liner for example is to be built into density to be about 1.5-6 pound/foot 3With the glass mat of thickness for about 0.5-2 inch.Described insulation is within it on the face or comprise a coating on " air-flow " surface.The air stream surface of insulation is by the surface of pipeline conveying air and is the reverse side on the surface of contact duct metal sheets in final conduit assembly.Described coating protection insulation, particularly pipe interior clean with water and/or all the more so during vacuum cleaning.If insulation is not protected, fiber just may be deviate from from insulation.In case after deviating from, they just may be taken away and circulated in whole building by air-flow, wherein their may be sucked by the people in the building.Within it the surface have coating the example of pipe lining at United States Patent (USP) 3,861, mention in 425 and 4,101,700.Also there is the pipe lining of the insulation of several coatings to sell: the trade name ToughGard_ of the CertainTeed Corp. of Pennsylvanian Valley Furistock by following company, Aeroflex_ and the Aeromat_ of the Owens Corning Fiberglas Corp. of Ohioan Toledo, Permacote_ and the Polycoustic of the Johns Manville Corp. of sieve Duola state Dan Fushi of section TMDuct Liner E.M with the Knauf Fiber Glass GmbH of state of Indiana Xie Erbiweier.
What know is, the microorganism that in the environment that has moisture and nutrient to exist, will grow, and many kinds of microorganisms have harmful effect to IAQ.Making in the pipe lining insulation moisture-free just suppress potential harmful microorganism grows in heating, heating ventilation and air-conditioning system.
In the manufacturing shop, heating, the manufacturer of heating ventilation and air-conditioning system cut pipe lining usually and it are followed closely on metallic plate.This manufacturing process has produced aperture and exposed in pipe lining slit, aqueous water can infiltrate to insulation from the pipeline outside thus.If aqueous water bleeds to insulation with these blemish in the pipe lining of the pantostrat coating of impermeability hydrophobic material by its gas transmission surface, then water can be assembled and be trapped in the insulation and support microbial growth.After this, microorganism can enter in the air supply system of building by the identical blemish that allows water to enter at first in the pipe element again.
In order to solve the problem of growth of microorganism in heating, heating ventilation and air-conditioning system, United States Patent (USP) 5,314,719; 5,379,806; 5,487,412 and 5,783,268 disclose on the gas transmission surface of impermeability pipe lining and/or pipeline clamping plate (the rigidity breather pipe of prefabricated installation) antimicrobial are provided.Yet these patents are not analysed in depth preventing to enter to the water gathering of pipe element and be trapped in the effective ways that form therein with microorganism in the fibrofelt plate pipe lining barrier material.In addition, antimicrobial has the extremely limited zone of action.That is to say, they only they recently around help to prevent the microorganism generation.For example United States Patent (USP) 5,314, and 719 have introduced about 1 millimeter antibiotic inhibition zone.Common pipe lining has the thick insulation of about 1-2 inch.In these goods, so limited inhibition zone is for preventing that being formed by the microorganism that pipe lining insulation (water saturation that it is entered by outer wall and slit by pipeline) causes is useless basically.
Therefore, the semipermeable coating that is suitable for use in through the pipe lining of coating or other building material made (having the thicker insulation layer that the microorganism that is easy to be caused by water saturation generates) has advantage.Described coating liquid towards water should be basically impermeable and be permeable to steam.Like this, can not enter to the steam that is included in the water in the insulation in the insulation by coating at the aqueous water of pipe interior and will pass coating, reduce the possibility of the growth of microorganism in the insulation thus to promote the drying of insulation.
Summary of the invention
The invention provides a kind of coating, have the plastics products for building that contains insulation of this kind coating and coating this kind coating method to the described plastics products for building.This coating has unidirectional " permeability " feature to the water and the aqueous solution.That is, this coating does not see through aqueous water basically, but and permeate water steam.Steam by the water in the insulation of coating coating can pass through coating thus, and prevented effectively aqueous water by coating with enter in the insulation.Thus, coating has prevented that not only dried insulation from being soaked by the lip-deep aqueous water of the coating that is retained in this insulation back side, and has promoted the drying of moist insulation.For example, in heating, heating ventilation and air-conditioning pipe lining, obtain at least two important advantages from these performances.Hydropexic possibility all is lowered with the pollution of the microorganism that follows to barrier material.And, because be repellency and have a substantial impermeability, the interior gas transmission surface of pipe lining can water or the aqueous solution of water and solvent or washing agent clean and nonwetting insulation.
Coating preferably comprises foam acrylic latex polymer, and it is applied on the insulation with low amount in the manufacture process of building product.The coating of low amount is important for keeping a semipermeability face coat.Excessive coating can make coating have the membrane structure of impermeability basically.The traded off acoustics usefulness of building material made of band coating of impermeability coating is because this coating has stoped some acoustic wave energies to dissipate in insulation.In addition, excessive coating has increased manufacturing cost and the permeability that has reduced (if not the words of eliminating) coatings.
By to implementing present preferred embodiment of the present invention and the following description carried out of preferable methods at present, other details of the present invention, purpose and advantage will become obvious.
