Abstract
The utility model relates to a multi-layer composite water-proof coil material which is used for building engineering. The utility model is characterized in that the lower surface has favorable roughness, and can solidly adhere to a base layer using cement paste as an adhesive. A main waterproof layer is made by combining two different types of water-proof materials and a fibrous reinforcement material, wherein, one water-proof layer is a resin film which is made by ethylene vinyl acetate copolymer and polyethylene resin as principal raw materials, and added by various auxiliaries; the other water-proof layer is an elastic layer which is made by acrylic acid ester matched with special cement and other auxiliaries.
Description
The utility model relates to construction engineering waterproof material, belongs to building field.
Waterproof material occupies very consequence in building material product, the quality of waterproof material quality directly has influence on the quality of whole architectural engineering.Conventional waterproof materials such as asphalt felt are because the shortcoming that self is difficult to overcome is eliminated gradually.
In recent years, some waterproof material development were very fast.As: modified asphalt felt, rubber and plastic class waterproof roll and water-repellent paint etc., these materials are significantly improved than conventional waterproof material at aspects such as intensity, extensibility, but ubiquity smooth surface and is difficult for the bonding with basic unit, or the shortcomings such as organic binder bond loss of properties on aging that are used to bond.And for example: double-side fibre strengthens polyethylene waterproof roll, though easily and basic unit bonding, but because its thin thickness is (less than 1mm, if thickness 〉=1mm, the coiled material flexibility is poor, constructional difficulties), anti-puncture ability, do not meet existing " Technical code for roof engineering " requirement, and coiled material self opposing ultraviolet ray ageing ability is not put into country always and recommends to use product.
The purpose of this utility model provides a kind of new type waterproof coiled material, make the coiled material lower surface have good roughness, available water mud is as binding agent and basic unit's bonding, main water barrier adopts two kinds of dissimilar waterproof materials and fibre reinforced materials to be composited, and performances such as the thickness of coiled material, intensity, flexibility, puncture resistance all meet or exceed the current specifications requirement, and particularly coiled material has good ultraviolet-resistant aging performance.
The utility model has the advantages that: 1. reliable water resistance.Owing to adopted multi-layer compound structure, made coiled material self possess the complete waterproof system of twice.2. good ultraviolet-resistant aging performance.Waterproof protective layer (1) is to be composited by the good acrylate of UV resistant performance and the inorganic material of stable performance, this waterproof protective layer had both had the elasticity and the water proofing property of organic material, the ageing-resistant performance that has inorganic material again makes coiled material have good ultraviolet-resistant aging performance.3. good weatherability.Coiled material uses in-20～+ 100 ℃ of temperature ranges, and not embrittlement is not trickled.4. easy construction.Because a rough surface of coiled material has advantages of good caking property with cement mortar, greatly reduces the requirement to basic unit's aridity during construction, also can construct under the situation of basic unit's humidity.
Accompanying drawing 1 is the application's a cross-section structure.
Among the figure, waterproof protective layer (1) is to be equipped with special cement, plasticizer, stabilizing agent, pigment and an amount of high quality filler by acrylate to make.Acrylate has high adhesive property, resistance to water and ultraviolet-resistant aging performance, and it and cement mixing have been given cement with elasticity and water resistance, and this waterproof protective layer had both had excellent waterproof property, again watertight composition (3) was had protective action.Cheap nonwoven is adopted in fibrage (2), (4).Watertight composition (3) is to be equipped with auxiliary agents such as antioxidant, plasticizer, ultraviolet light screener for primary raw material by ethylene-vinyl acetate copolymer (EVA), polyethylene (PE), extrude the resin molding that forms after mixing on extruder, this resin molding has good flexibility, elasticity, weatherability, toughness and shock resistance.During production, when the resin molding that extruder is extruded is entering compounding machine, the feeding nonwoven, form the fiber-reinforced composite resin film through composite roll hot pressing, one side at composite resin membrane is coated with waterproof overcoat (1) again, drying, cooling, and rolling forms this product.
Claims (3)
1. a novel multi-layer composite of water-proof coiled material is characterized in that it is to be composited by waterproof protective layer (1), fiber-reinforced layer (2), watertight composition (3), fiber reinforcement skid resistant course (4).
2. waterproof roll as claimed in claim 1 is characterized in that waterproof protective layer (1) is to be equipped with special cement, plasticizer, stabilizing agent, pigment and an amount of high quality filler by acrylate to make.
3. waterproof roll as claimed in claim 1 is characterized in that watertight composition (3) is is that primary raw material is equipped with auxiliary agents such as antioxidant, plasticizer, ultraviolet light screener and makes by ethylene-vinyl acetate copolymer, polyethylene.
