Description

Water-proofing composition and method for making thereof and application
Summary of the invention
The object that the present invention relates to water-proofing composition and handled with described water-proofing composition.The invention still further relates to the method that is used to produce water-proofing composition, give the method for object water-repellancy and the method for production waterproof object.The invention still further relates to object and the purposes of using described composition and method.
Background of invention
Water-proofing composition can be used for giving various object water-repellancies.Particularly, these objects are included in sheet material used in the building industry and blank material.Sheet material and blank material package used in building industry are drawn together plasterboard, plaster board, wallboard, plaster board, big hollow wallboard, brick, reinforcement, support or are kept solids of solid position or the like.Yet it also is understandable that water-proofing composition can be used for wide variety of objects, and these objects comprise food, makeup, wrapping material and other article.
Particularly, the shortcoming of aforementioned sheet material and blank material is to lose needed performance such as intensity, flame retardant resistance, sound insulation or the like because of water-absorbent.
Particularly, building board and blank material such as plaster board, plasterboard or wallboard, perhaps to be called plaster board, hollow core slab and reinforcement, support or to keep the solids of solid position be by anhydrous calciumsulphate and calcium sulfate hemihydrate and water reaction, and make mixture become hydrate or be solidified as harder calcium sulphate dihydrate production.
Usually form building board such as plaster board, plasterboard or wallboard by the core that is positioned in the set gypsum (set gypsum) between the secondary outer liner plate, this outer liner plate forms building board outside surface separately.Should generally make by outer liner plate by paper or fiberglass.
Core by the set gypsum of the fiber reinforced material of the Mierocrystalline cellulose that contains random dispersion or glass fibre or analogue forms plaster board.Gypsum core can be placed on the liner plate of paper or fiberglass, or be placed between two liner plates, or be cast on the belt without any liner plate, wherein set gypsum composition forms the surface of finished product sheet material.
By can containing or fiber reinforcement-containing not, and can cast or be not cast on the liner plate or the core that is placed in two set gypsum between the liner plate forms large-scale hollow core slab.Plate casting in the mould with placement hollow tube wherein, can be removed it after the gypsum sets.These large-scale hollow core slabs are used as the structure bearing wall assembly of interior wall and exterior wall usually.
Form brick and reinforcement, support or keep the solids of solid position by the set gypsum that can contain Mierocrystalline cellulose or glass fibre reinforcement or analogue.The solids of casting brick or reinforcement in mould, support or maintenance solid position.
In application, these building boards and blank material are subjected to the influence of water easily usually, and because set gypsum easily absorbs water, and this water-absorbent causes injurious effects noted earlier, that is, and the loss of intensity, resistivity against fire etc.
When applying this product with known water-proofing composition, people find to use on object water-proofing composition of the present invention can improve the water-repellancy of object unexpectedly.In addition, owing in the forming process of sheet material, need less water, use water-proofing composition of the present invention can help improving the output of water proof building sheet material.
The present invention attempts perhaps to provide a kind of useful adoptable method at least by giving improved water-repellancy to improve the shortcoming of known water-proofing composition.
