Abstract
The utility model discloses a waterproof anti-sticking film comprising a polypropylene base layer. The waterproof anti-sticking film is characterized in that an anti-sticking layer is arranged on the surface of the polypropylene base layer. According to the preferable embodiment of the utility model, the thickness of the polypropylene base layer is 0.020-0.050mm and the thickness of the anti-sticking layer is 0.001-0.003mm. The waterproof anti-sticking film disclosed by the utility model has the beneficial effects that a polypropylene material is used as a base layer; only if a silicon coating is coated on the basis of an existing polypropylene base layer to be used as a waterproof anti-sticking layer, the waterproof anti-sticking film has the advantages of high temperature resistance, flatness and transparency of PET (Polyethylene Terephthalate), and also has the extensibility and toughness of PE (Polyethylene) materials. Therefore, the waterproof anti-sticking film disclosed by the utility model is convenient to manufacture and is flat and transparent; and the waterproof anti-sticking film can resist the temperature of up to 165 DEG C, and has good extensibility and toughness.
Description
Technical field
The utility model relates to a kind of antiadhesion barrier of waterproof roll, specifically, relates to a kind of waterproof antiadhesion barrier.
Background technology
At present, the waterproof roll of selling on China market mainly contains three major types, that is: 1. modified asphalt waterproof coiled materials; 2. high molecule plastic sheet material; 3. rubber water-proofing coiled.Wherein, modified asphalt waterproof coiled 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 is with 50% speed increment.The construction method of these coiled materials in general application project work progress has again three kinds, that is: paste in basic unit after 1. use benzine blow lamp heating and melting pitches, as: modified asphalt waterproof coiled material; 2. paste on the base with cold binding agent brushing, as: high molecule plastic sheet material and rubber coiled material; 3. the self-adhesion with coiled material itself pastes in basic unit, as: self-adhesive modified asphalt waterproof rolling material, with high molecule plastic sheet material and the rubber coiled material of self-adhesive layer.The operation that all needs to have an overlay film in self-adhesive modified asphalt waterproof rolling material and the production process with the high molecule plastic sheet material (coiled material) of self-adhesive layer and rubber coiled material, the purpose of overlay film is in order to make coiled material not adhesion mutually in the packing wrapup procedure, and can take off easily when application and construction, expose after self-adhesive layer and cement based aspect good bond, the film of this covering is called antiadhesion barrier.
Current, domestic each supplier's antiadhesion barrier mainly contains following several:
1. release liners or claim barrier paper.Its production method is to spoon one deck low-density polyethylene film on a surface or two surfaces of different grammes per square metre brown paper or crimped paper, then, then is coated with the adherent layer of one deck silicon resin;
2. PET barrier film.Its production method is to coat the adherent layer of silicon resin through the pet film surface of biaxial tension;
3. PE antiadhesion barrier.Its production method is to coat silicon resin on the surface of high density polyethylene (HDPE) blown film.
But exist some shortcomings in the actual use of existing antiadhesion barrier, specific as follows:
1. release liners or claim barrier paper
This product deflection is 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 yuan; In addition, papery is not water-fast, in the production process of coiled material cooling slow, extensibility is little, easily make product produce darker rolling wrinkle, has a strong impact on the waterproof quality of coiled material.
2. polyester insulating film (PET barrier film)
This product is transparent, matter is thin, intensity is high, water-fast and heat resistance good (can reach more than 170 ℃), price low (every square meter cost only needs 0.4～0.6 yuan).But raw material are in short supply, and " foreign rubbish " secondary of main dependence on import uses film, and the restriction of national policy causes the source of goods not enough.And this product also exists more crisply easily tear winter, and summer, difficulty was opened the shortcoming of film, and the workmen uses inconvenience.Simultaneously, also easily make coiled material produce shrinkage mark in production process, affect product quality.
3. polyethylene antiadhesion barrier (PE antiadhesion barrier)
This product has extensibility preferably, can avoid producing in the coiled material production process stretching wrinkle, water-tolerant, moderate (0.6～0.8 yuan/m
2) etc. advantage.But the intensity of material is low, and temperature tolerance is poor, easily produces in production process and scalds film contraction or silicon transfer phenomena, causes fault in production.
In sum, at present the polyethylene antiadhesion barrier is the lower and extensibility of cost product preferably in current antiadhesion barrier product, but if provide the better and intensity of a kind of temperature tolerance preferably waterproof will have larger social value and economic worth with antiadhesion barrier.
Summary of the invention
The technical problem of the required solution of the utility model is to provide a kind of more practical, more economical, more environmental protection, waterproof antiadhesion barrier that the scope of application is wider.
For realizing the utility model above-mentioned purpose, the technical solution of the utility model is as follows: a kind of waterproof antiadhesion barrier, comprise polypropylene based layers, and it is characterized in that: be provided with one deck adherent layer on this polypropylene based layers surface.
According to preferred embodiment of the present utility model, the thickness of described polypropylene based layers is 0.020 ~ 0.050mm, and the thickness of described adherent layer is 0.001 ~ 0.003mm.
The beneficial effects of the utility model are: the utility model adopts polypropylene material as basic unit, only need to coat silicon coating as the waterproof adherent layer on the basis of existing polypropylene based layers, make it both have the high temperature resistant of PET, the advantage of flat transparent has again extensibility and the toughness of PE class material.Therefore the utility model has the advantage of easy to make, and flat transparent, heatproof can reach 165 ℃, has good extensibility, toughness.
Description of drawings
Fig. 1 is the waterproof antiadhesion barrier structural representation that the utility model provides.
Concrete embodiment
A kind of waterproof antiadhesion barrier comprises polypropylene based layers 1, it is characterized in that: be provided with one deck adherent layer 2 on this polypropylene based layers 1 surface.
According to preferred embodiment of the present utility model, the thickness of described polypropylene based layers 1 is 0.020 ~ 0.050mm, and the thickness of described adherent layer 2 is 0.001 ~ 0.003mm.
This polypropylene based layers 1 can adopt existing polypropylene material to make, and does not therefore repeat them here.
This adherent layer 2 is than the slightly thin 0.001mm of adherent layer of existing PE antiadhesion barrier, because of polypropylene surface more smooth.

2) coating antitack agent
(1) open hot-blast stove, each district send hot blast toward coating line;
(2) thickness, width, polypropylene screen that the corona value is qualified are placed on fixing support, it is 6～10N that tension value is set;
The antitack agent that (3) will prepare in advance evenly is placed in coating pan;
(4) start conveyer belt, the polypropylene screen that unreels from above-mentioned steps (2) is taken away antitack agent through the antitack agent groove, enters drying tunnel, carries out intermediate temperature setting;
(5) setting drying tunnel, respectively to distinguish temperature be 100,110,120,130,140,120,110,90,80 ℃, and setting coating line speed is 60～90 m/min;
(6) online sampling, detect remaining adhesive rate and peeling force that silicon solidifies, monitors these indexs and whether meet company standard;
(7) make the polypropylene antiadhesion barrier that the antitack agent layer thickness is 0.001～0.003 mm (concrete structure as shown in Figure 1), the rolling packing.
