Description
Technical field
The present invention relates to the building waterproofing technique field, be specifically related to a kind of composite of water-proof coiled material of using and form composite of water-proof coiled material that uses in two-sided closely connected waterproofer's method and the said worker's method and preparation method thereof in building structure.
Background technology
Along with rapid economy development, building size enlarges, and the personalization of building, variation are more outstanding, and still, people still are accustomed to adopting waterproof method in the past, as with EPDM, PVC or non-tar polyurethane coating.At present on waterproof market popular waterproofing materials, no matter be that coating or coiled material also are non-tar polyurethane coating, all there is the difficult problem that can not solve in these materials from beginning the later maintenance of constructing, and specifically comprise following several aspect:
(1) general waterproof roll, but how to join together these good coiled materials, forming the waterproofing course that is waterproof together is a difficult problem, the processing of overlap joint, node has become the key point of waterproof roll construction.
(2) material of some waterproofing materialss is too soft, a bit hard thing is arranged slightly just easily material damage, like non-tar polyurethane, modified bitumen etc.If there are indivedual grains of sand in basic unit, be easy to by bursting after waterproofing course is done, and some utensils of job site just are corrupted to waterproofing course easily.The way of basement side wall topping particularly, the protective material that most of waterproofing materials adopts all is a cystosepiment, such topping is difficult to cement with waterproofing course.
(3) rigidity water-proofing material is prevented the crack that unknown malformation causes.
(4) traditional flexible waterproof material separates with structure basically, does not have great adhesion stress, as long as a point is destroyed, water will be from getting into the back side of waterproofing course here, and the leakage point of structure often is not the real damaged points of waterproofing course.The time be difficult to the leakage point that finds waterproofing course real in maintenance, almost can't keep in repair.
Summary of the invention
Technical problem to be solved by this invention is the shortcoming that exists to above prior art, provide a kind of can with building structure buildings waterproof worker closely connected, easy construction method, used composite of water-proof coiled material and preparation method thereof.
For realizing above-mentioned purpose, technical scheme provided by the present invention is:
A kind of buildings waterproof worker method; One polymer cement binding material of brushing on the building structure basal plane; Lay the vinyl polymer composite of water-proof coiled material then; Polymer cement binding material and waterproof roll are chimeric each other, complementary, compatible, fit tightly the tack coat (enhancement layer) that forms deck and coiled material layer, form one with building structure layer and the two-sided closely connected integral waterproofing layer of rigid waterproofing topping.On waterproof roll, smear cement mortar (topping), the terylene non-woven fabric of cement mortar (topping) and waterproof roll surface layer is chimeric each other, fit tightly and form protection waterproof roll and the compatible skin of waterproof, and it specifically may further comprise the steps:

Above-mentioned tower connects mode, its lap width: long limit is not less than 80mm, minor face is not less than 100mm.
(5) repeat above-mentioned steps (2)～(4), can constitute dual waterproof construction.
A kind of preparation method of composite of water-proof coiled material of above-mentioned buildings waterproof worker method, it comprises screw injection molding machine, it comprises the steps:
(1) injection machine preheating: with screw rod, the heating earlier of die apparatus heating position 1.5～2.0 hours;
(2) batch mixes: polyvinyl and black masterbatch are placed on stir mixing in the batch mixing pot, and dried moisture 10～20 minutes;
(3) extrusion molding: batch mixing is put into hopper, rotated by screw rod and inject raw material, raw material is squeezed into the polyvinyl resin film through the screw rod and the mould of heating;
(4) the compound enhancing tack coat of pressurization: the polyvinyl resin film is gone out to three roll-ins to prolong by the mould mouth, and calendering is rolled roller chopped fiber needle-punched non-weaving cloth is compound to polyvinyl resin film two sides, is extruded to shape through press roll, forms composite of water-proof coiled material;
Wherein, most importantly will regulate calendering and roll the pressure at two ends of roller and the rotating speed of pressure roller, pressure must keep the both sides balance, accomplishes that two sides bonding enhancement layer combined state is good, does not peel off waterproofing course, phozy, but does not injure the inner membrance position of coiled material
(5) traction cutting edge rolling, packing go out finished product.
Wherein, above-mentioned steps (1), the heating-up temperature of screw portion should be gradually high by hanging down: 130 ± 5 ℃ of (4) districts, 110 ± 5 ℃ of (3) districts, 100 ± 5 ℃ of (2) districts, (1) district 150 ± 5 ℃ (5) distinguish 190 ± 5 ℃ in 170 ± 5 ℃ (6) district.
