- BIOCIDAL GRANULE IN PARTICULAR FOR THE MANUFACTURE OF
- the present invention relates to granules having a biocidal activity, especially with regard to algae, intended in particular for producing asphalt shingles.
- Asphalt shingles are traditionally used in North American countries as facade or roof cladding for residential buildings.
- organic roofing shingles There are two types of shingles depending on the nature of the reinforcing reinforcement that composes them: "organic” shingles based on a thick felt of wood fibers or cellulose, and shingles “fiberglass", no woven, held together by an insoluble binder in water.
- the manufacture of organic roofing shingles consists of continuously unrolling the dry felt of organic fibers and passing it through an accumulator device composed of several rotating rollers to bring it into a first bath of liquid asphalt (temperature of the order of 25O 0 C). At the exit of the bath, the felt passes into a second accumulator device to allow the felt to absorb excess asphalt and to cool slightly.
- the impregnated felt is then coated with molten asphalt on both sides, colored granules are distributed on the upper face and a release agent, for example talc, is applied on the underside.
- a release agent for example talc
- the manufacture of fiberglass shingles is carried out under the same conditions.
- the main function of the asphalt is to make the material impervious to water. It also serves as a support for the granules, gives resistance to the material and its highly ductile nature makes it possible to obtain a flexible product that is easy to implement.
- the longevity of the shingle increases with the amount of asphalt.
- the granules generally mineral, have the role of giving the shingle good durability: they protect the asphalt from the effects of solar radiation (in particular ultraviolet rays) and the environment (climatic aggressions, pollution, ...) , and contribute to a better reflection of light.
- the granules are further colored, naturally or artificially by the application of pigments, to meet the requirements of the user in terms of aesthetics.
- Green, brown or black stains on asphalt shingle surfaces of buildings in temperate climates are common. These spots are due to microorganisms, mainly algae of the genus Gloeocapsa which benefit from favorable conditions for their growth: heat, humidity and nutrients in large quantity, the essential mineral elements that are provided by the mineral granules but also the organic matter that settles on the shingles.
- the unsightly nature of these spots, especially pronounced that the color of the shingle is clear, is not the only drawback; the darkening of the surface, which absorbs more solar radiation, reduces the insulating nature of the material and reduces its life.
- one way is to treat the contaminated parts with suitable biocides.
- Complete removal of algae is difficult and requires treating the entire building, including apparently healthy surfaces.
- Even using a strong biocide such as sodium hypochlorite the effect is not permanent due to leaching by rainwater and runoff.
- some green algae particularly resistant to biocides can re-colonize already treated surfaces thus imposing additional treatments, at regular intervals, to limit their reappearance.
- Other means known to prevent the appearance of undesirable stains are based on the incorporation of algaecide in the shingle.
