Abstract
The invention discloses a preparation method of a multilayer waterproof sheet, which is prepared by adopting an extrusion three-roll calender set to calender and form at one step, wherein the EVA waterproof sheet and non-woven polypropylene fiber are subjected to hot pressing through a three-roll calender set to prepare the composite EVA fiber waterproof sheet through hot pressing. After the material is used, once leakage caused by local damage occurs, the material is only limited in the range of leakage points, so that the phenomenon of water channeling of the sheet material can be effectively prevented, and the whole or part of the waterproof layer is prevented from losing efficacy. The method can be widely applied to waterproof engineering of subways, roads, ports and docks, culverts, dam pools and underground large-scale engineering.
Description
Technical field
The invention belongs to the preparation field of water-proof building material, the preparation method relating to a kind of multilayer flashing sheet material. .
Background technology
Major part adopts atactic polypropylene (APP) modified bituminous waterproof sheet material (APP) waterproof layer or brushes various water-repellent paint at present, solves or prevent the generation of bridge floor Moisture Damage. Bitumen concrete bridge floor Water Damage is owing to Freeway Traffic Volume is big, speed is fast, vehicle capacity is big, and the shearing during load car braking that wheel produces on pave-load layer is very big, accelerates the destruction of bridge deck pavement. It is that the waterproof layer effect arranged between bitumen concrete and Cement Concrete bridge floor is undesirable that the major reason that bridge floor water damages occurs. and rainwater penetrates into and is accumulated on Cement Concrete bridge floor. and under the repeated action of traffic load, Cement Concrete surface softens gradually and causes purt to starch, bituminous concrete and cement concrete are peeled off, shearing resistance reduces, occur pasta to stop up bag, Colophonium cohesive force reduces, pasta cracking is loosely formed pit etc., reduce the service life of surface layer, jeopardize traffic safety. Due to the physical property of waterproof material, malformation, construction and protect the reasons such as improper, leakage of building remains the Universal Problems on puzzlement building circle. By deficiencies such as the elasticity of material, percentage elongation, tensile strength, durability, lower temperature resistance differences, directly do not bond with building and cement; Or the polymer modified bituminous waterproof sheet material of thermo-compression bonding.
At present, the predominant plastics splash guard of domestic production has multiple: such as has employing SBS, SBR etc. for modifying agent, is equipped with viscosifier, plasticizer etc. and is developed into self-adhesive rubber asphalt waterproofing coiled material; Also useful polyethylene sheets SBS modified asphalt waterproof coiled material the waterproof system by bonding, sealing have been studied; Also there is the technical matters adopting super-high relative molecular weight polrvinyl chloride (UHMWPVC) with asphalt blending and modifying compound system. But single ECB material also exists some problems: 1 and building and cement directly do not bond. 2, easily channeling water is laid after EVA waterproof roll, not easily water source finding channeling water etc. defect after channeling water.
Summary of the invention
It is an object of the invention to the shortcoming overcoming prior art with not enough, it is provided that the preparation method of a kind of multilayer flashing sheet material.
The multilayer flashing sheet manufacturing process of the present invention, it is characterised in that it adopts extrusion three-roller calendaring unit and the one-time formed method of two-roll calendar continuous calendering, carries out as follows:
(1) by EVA granule, thermoplastic elastomer SBS and other auxiliary agent after high-speed mixer mix homogeneously, entering extruder hopper, extruded three-roller calendaring unit rolls, and makes certain thickness width EVA waterproof sheet;
(2) with non-woven fabrics polypropylene fiber, EVA waterproof sheet being passed through two-roll calendar, multilayer flashing sheet material is made in hot pressing;
(3) the multilayer flashing sheet material that will make, by cooling down traction, meter is long, then cuts off, and packs after inspection.
In multilayer flashing sheet manufacturing process of the present invention, it is 140��185 DEG C that extruder barrel controls temperature; It is 180��195 DEG C that clothes hanger die lip controls temperature. The temperature of two-roll calendar therein is 140��150 DEG C.
Non-woven fabrics polypropylene fiber of the present invention, its weight is: 250g, 300g, 350g, i.e. every weight per square meter 250g, 300g, 350g, and width is 2.0��2.5 meters.
Material used by the present invention is non-woven fabrics polypropylene fiber to be made it be combined into LECB waterproof sheet by two-roll calendar heating pressure method to be integrated. Wherein non-woven fabrics polypropylene fiber layer is able to bond with cement (basic structure) better as surface layer role, and LECB flashing sheet material layers plays waterproof action, as waterproof and basic unit. Non-woven fabrics polypropylene fiber is as surface layer, it on the one hand can be bonding with the cement of basic structure (i.e. structure trunk), another aspect, it can increase intensity: non-woven fabrics polypropylene fiber of the present invention directly contacts with bituminous concrete after laying, improve the adhesion strength between them, it is prevented that layering is skidded.
