Description

Wet coating self-adhering waterproof coiled material and production method thereof and job practices
(1), technical field
The present invention relates to a kind of waterproof roll and production method thereof and job practices.
(2), background technology
Existing waterproofing materials mainly is high polymer SBS modified bitumen and synthetic polymeric waterproofing material etc., waterproof rolls such as high polymer SBS modified bitumen and synthetic high polymer are the waterproof materials faster of demand growth in recent years, it has solved asphalt felt high temperature trickling in the past, the defective of low-temperature embrittleness, boundary of works area is wider, is the waterproof product of Ministry of Construction's emphasis popularization and develop actively.But basic unit's primary coat is adopted in existing waterproofing materials construction, is coated with the blowtorch heating is roasting, or with the binding agent bonding, easily produces oil smoke and toxic gas, and it is healthy to diminish the constructor, also can produce pollution to environment.And existing waterproofing materials is higher to Base Smoothness and water content requirement, basic unit's water content is required below 9%, and often do not reach in operating process, not only influences the duration, also has influence on waterproof effect.As do not reach standard, and construction back waterproofing course easily produces bubble, and problems such as water are scurried in delamination, also can occur can not realizing waterproof under water because of the not firm seepage phenomenon that causes of overlap joint.Existing waterproof roll does not have the suspender belt that passes the flexible anti sheath, is difficult for being connected and fixed in the construction of facades such as tunnel, and construction is inconvenient.
(3), summary of the invention
The purpose of this invention is to provide a kind of wet coating self-adhering waterproof coiled material and production method thereof and job practices, the waterproofing course that solves cold-adhered easily produces bubble, and the problem of water is easily scurried in easily delamination; And solve the problem of carrying out waterproof construction in wet environment and the water; Also solve high score subclass coiled material because of the not firm leakage problems that causes of overlap joint; Solve waterproof roll simultaneously and in the construction of facades such as tunnel, be difficult for being connected and fixed the problem that construction is inconvenient.
Technical scheme of the present invention: this wet coating self-adhering waterproof coiled material, it is characterized in that this coiled material has sticking folded following each layer of order: separation layer, self-adhesive sealant, macromolecule water-proof sheet material, adhesive linkage, flexible anti sheath, above-mentioned flexible anti sheath is installed with suspender belt, expose at suspender belt two, is used for colligation.
Above-mentioned macromolecule water-proof sheet material can be high density polyethylene (HDPE), low density polyethylene (LDPE), polyvinyl chloride, polyvinyl acetate synthetic resin, ethene, vinyl acetate pitch mixture macromolecule water-proof sheet material or modified bituminous pitch coiled material.
Above-mentioned flexible anti sheath can be nonwoven, cloth, polyethylene felt, felt, malthoid, glass felt or macromolecule plastic film.
Above-mentioned separation layer can be silicone oil paper or polyester insulating film.
The material of above-mentioned self-adhesive sealant is the butyl rubber modified bitumen, and its mixing ratio by weight is as follows:
Butyl rubber 268; 8~28%;
Oxidized asphalt: 30~50%;
Acrylic acid water-absorbing resin: 1~8%;
Process oil: 5~35%;
Filler: 5~25%;
Stop-off gent: 1~5%.
Aforesaid operations oil comprises naphthene base crude oil or three-way base oil.
Above-mentioned filler comprises fossil meal or carbon black.
Above-mentioned stop-off gent comprises fume colloidal silica and glue.
The production method of above-mentioned wet coating self-adhering waterproof coiled material, it is characterized in that: by butyl rubber, High Quality Oxidized Asphalt through high-temperature mixing, add the acrylic acid water-absorbing resin, process oil, filler, stop-off gent are made from bonding waterproof sealing material through high speed dispersion, dip-coating is on macromolecule water-proof sheet material carrier one side, through rolling, extruding, spread separation layer as adherent layer, and the flexible anti sheath is pasted macromolecule water-proof sheet material carrier another side, put on suspender belt again, make wet coating self-adhering waterproof coiled material.
The job practices of above-mentioned wet coating self-adhering waterproof coiled material, it is characterized in that: the fixture of pre-buried band hook in concrete basic unit, with the flexible protective aspect of wet coating self-adhering waterproof coiled material to concrete basic unit, and fix by the hook of suspender belt and fixture, throw off the separation layer of wet coating self-adhering waterproof coiled material, make the concrete deck on self-adhesive sealant surface, waterproof roll and concrete deck fully are sealing adhesive.
Beneficial effect: cold-adhered water-tight performance of the present invention is good, and it is to add acroleic acid macromolecular absorbent resin and macromolecule water-proof sheet material is a carrier with butyl rubber and high-quality asphalt, by dipping process, is the waterproof roll that adherent layer is made with the separation layer.The flexible protective layer has self-adhesion, waterproof, three kinds of functions of protection, can also make wet coating self-adhering waterproof coiled material have protective effect as the carrier of hanging suspender belt, and be easy in the facade construction fixing.Owing to penetrate the suspender belt that fixedly colligation is used in the flexible anti sheath, make the facade of waterproof roll fixing very convenient.In construction, can adopt to overlay anti-subsides method or routine and just pasting legal system and make waterproof construction, utilize the moisture of cement mortar, the migration by water-absorbing resin reaches fully waterproof roll and is sealing adhesive, but reaches wet environment construction and subaqueous work.Waterproofing materials construction of the present invention does not need to be coated with the blowtorch heating is roasting without basic unit's primary coat, bonds without binding agent yet.Intensity height of the present invention, elongation per unit length are big, acid and alkali-resistance, ageing-resistant, corrosion-resistant, anti-puncture, self-healing property, cold construction, solvent-free volatilization are arranged, safety and environmental protection, no hidden fire-fighting danger, construction are convenient, but bond in wet environment or the water, duration can be saved, accelerate speed of application, guarantee waterproof effect and construction quality, energy-conserving and environment-protective.The invention solves existing waterproofing materials and easily produce bubble, the problem of carrying out waterproof construction in water problems and wet environment and the water is easily scurried in easily delamination, has especially solved high score subclass coiled material because of the not firm leakage problems that causes of overlap joint.Be mainly used in the construction works higher such as underground, tunnel, bridge, subway, planted roof to waterproof requirement.
