Description
Technical field
The invention belongs to the water-proof material technical field used in water conservancy, civil engineering, relate to one specifically and easily weld waterproof roll and preparation method thereof without folding line.
Background technology
Waterproof roll is a kind of novel high-grade water-proof material grown up in recent years, is mainly used in the basal plane WATER REPELLENT in water conservancy, civil engineering.Waterproof roll includes the synthetic resin sheet material forming its tire basic unit, the separating film layer being compound in the tackiness agent formed by modifying asphalt on above-mentioned tire basic unit one or both sides and laminating surface of pressure-sensitive adhesive; All rolling is deposited or is transported in process of production.During use, coiled material is spread out and peels off separating film layer, bonded by binder layer and engineering basal plane, realize the function of WATER REPELLENT.But there is following defect in current used coiled material: one, after depositing for a long time or piling up transport, because extruding result in the distortion of coiled material, lay when launching to use that to be difficult to nature smooth, can must realize paving within the longer time by means of external force, especially construct at low ambient temperatures, be difficult to the laying completing water-proof material coiled material in the short period of time especially; Its two, hot melting temperature o'clock at about 450 DEG C, the welding procedure difficulty between sheet material.
Summary of the invention
Object of the present invention is just to provide one and easily welds waterproof roll and preparation method thereof without folding line.
The technical scheme realizing above-mentioned purpose of the present invention is:
One easily welds waterproof roll without folding line, the barrier film that its structure comprises sheet material, is compound in the non-bituminous self-adhesive glue layer on one side or two sides and is overlying in described self-adhesive aspect, is characterized in that: described sheet material comprises the polyolefine anti-aging agent of the polyethylene of 65-70 weight parts, the POE of 15-18 weight parts, the EVA of 10-12 weight parts, the polyethylene toughner of 5-7 weight parts, the maleic anhydride compatilizer of 4-6 weight parts and 1-2 weight parts.
Wherein, the thickness of described sheet material is arranged on 0.2mm-2.0mm, and the thickness of described non-bituminous self-adhesive glue layer is 0.3mm-1.0mm.
One provided by the present invention is easily welded waterproof roll without folding line and is compared with the existing technology had the following advantages: one, this coiled material has good elasticity restorability, after crimp, generally recover open and flat in expansion in 20 minutes, and can according to the conversion of formation level because gesture converts, lay docile property good, avoid producing because formation level is asynchronous with water-proof material water-proof material local stress and be out of shape even braking effect water resistance and change the generation of situation; Two, this product hot melting temperature is low, easy welding procedure, is ensureing that under the prerequisite that welding effect is superior, comparatively the low 50-80 DEG C of welding temperature compared by common material, greatly saves the energy consumption of welding set; Three, this coiled material has that fracture tensile strength is high, tension set is large, and tear strength is high, the performance of resistance to chemical attack etc., can be widely used in the underground waterproof engineering such as tunnel, culvert, subway.
