Description
Technical field
This utility model belongs to the field of adhesive waterproof coil, particularly relates to a kind of moistureproof antiadhesion barrier, it is adaptable to adhesive waterproof coil。
Background technology
At present, adhesive waterproof coil China market sold mainly has three major types, it may be assumed that 1. Modified asphalt self-adhesion waterproof rolling material;2. polymer plastic media sheet;3. rubber adhesive waterproof coil。Wherein, Modified asphalt self-adhesion waterproof rolling material accounts for the leading position in application, and 2010 annual productions reach 400,000,000 square metres, and self-adhesive coiled material accounts for 30%, and every year with the speed increment of 50%。These coiled materials construction method in general application project work progress has again three kinds, it may be assumed that paste in basic unit after 1. heating molten asphalt with benzine blow lamp, as: Modified asphalt self-adhesion waterproof rolling material;2. paste on base with cold binding agent brushing, as: polymer plastic media sheet and rubber coiled material;3. paste in basic unit with the self-adhesion of coiled material itself, such as: self-adhesive modified asphalt adhesive waterproof coil, polymer plastic media sheet with self-adhesive layer and rubber coiled material。Self-adhesive modified asphalt adhesive waterproof coil and the polymer plastic tablet (coiled material) with self-adhesive layer and the production process of rubber coiled material are required for the operation of an overlay film, overlay film in order that make the coiled material will not adhesion mutually in packaging wrapup procedure, and can take off easily when application and construction, expose after self-adhesive layer with cement based aspect good bond, the thin film of this covering is called antiadhesion barrier。
Currently, the antiadhesion barrier of domestic each supplier mainly has following several: 1. release paper or title release paper, its production method is to drench last layer low-density polyethylene film on a surface of different grammes per square metre kraft paper or crimped paper or two surfaces, then, repastes the adherent layer of one layer of silicones;2.PET isolating membrane, its production method is to coat the adherent layer of silicones on the pet film surface through biaxial tension;3.PE antiadhesion barrier, its production method is to coat silicones on the surface of high density polyethylene (HDPE) blown film。But existing antiadhesion barrier actually used in there are some shortcomings, specific as follows: 1. release paper or claim this product deflection of release paper better, can play a supporting role, and easily tear off。But, material cost is higher, and the price of every square meter needs 1.3-1.5 unit;Additionally, papery is not water-fast, in the production process of coiled material, cooling is slow, extensibility is little, easily make product produce deeper rolling wrinkle, has a strong impact on the waterproof quality of coiled material。2. this product is transparent, matter is thin, intensity is high, water-fast and heat resistance good (can reach more than 170 DEG C), price low (every square meter cost only needs 0.4-0.6 unit) for polyester insulating film (PET isolating membrane)。But, raw material is in short supply, and " ocean rubbish " secondary relying primarily on import uses film, and the restriction of national policy causes the source of goods not enough。And, this product there is also more crisp easily to be torn winter, and summer, difficulty opened the shortcoming of film, and workmen uses inconvenience。Meanwhile, production process also easily makes coiled material produce shrinkage mark, affect product quality。3. polyethylene antiadhesion barrier (PE antiadhesion barrier) this product has good extensibility, can avoid producing in coiled material production process to stretch the advantages such as wrinkle, water-tolerant, moderate cost (0.6-0.8 unit/m2)。But, the intensity of material is low, and temperature tolerance is poor, is easily generated boiling hot film and shrinks or silicon transfer phenomena, cause fault in production in production process。
