Description
Technical field
The present invention relates to a kind of waterproof material preparation method and products thereof, particularly synthetic waterproof sheet preparation method of a kind of rubber chemical fibre and products thereof; Be mainly used in architectural waterproof material and waterproofing work field thereof, relate in particular to the actual application in engineering of waterproof (volume) sheet material.
Background technology
Flashing (volume) material, water-repellent paint are main two big series of waterproof material, and waterproof sheet outstanding place leading position in the buildings waterproof of China is used has played important function in construction waterproofing engineering, be the waterproof material that a class has a large capacity and a wide range.
The present kind of buildings waterproof sheet (volume) material by the fifties in last century single asphalt felt develop into tens kinds of medium and high-grade new waterproof sheet materials.Flashing (volume) material commonly used is divided into according to the unusual of material: asphalt waterproofing sheet (volume) material, high-polymer modified pitch flashing (volume) material, synthetic high polymer (rubber, plastics) flashings (volume) material also has several big classes such as polymer cement waterproof sheet (volume) material, metal flashing (volume) material herein.
Flashing (volume) is though material is various in style by material, as long as its construction method is divided into thermal technology's method and cold worker's method two big classes are just passable.Weigh the quality of flashing (volume) material, not only will see the quality of flashing (volume) material itself, and should note its construction quality.The quality of flashing (volume) material self is the problem of local fritter just, and construction quality is the big problem of whole whole waterproofing work.Therefore we have to pay attention to the construction quality of flashing (volume) material.Let us is had a look at the construction of all kinds of flashings (volume) material now, and the internal relation of this worker's method and waterproofing quality, just can know value of the present invention place.The construction of flashing (volume) material mainly contains following several now:
One, thermal technology's method
Thermal technology's method comprises that hot melt, the roasting method of spray, three kinds of forms of welding (mainly use the construction of what plastic sheet (volume) material, general and mechanical Fixing Method combines to be made, and has specifically introduced below again) are now introduced respectively.
1, hot melt
Worker's method of hot melt melts the pitch code tellurium fat in the canister or plastic ointment with the naked light heating for install canister in the building site, strike off rapidly while hot on the basal plane that the pitch code tellurium fat that will melt then or plastic ointment are poured on waterproofing work and spread out, again asphalt waterproofing sheet (volume) material or glass cloth are spread, reached the purpose of stickup.Repeat this kind worker method, the front and back construction surface is connected, finish the construction task of whole waterproofing work.The advantage of this worker's method is to realize combining closely of watertight composition and basic unit, is conducive to strengthen the waterproof effect of watertight composition.Its shortcoming is; (1) naked light at the construction field (site) causes security incident easily.(2) these pitch tellurium fat and plastic ointment can distribute pungent toxic odor, serious environment pollution.So a lot of cities, the whole nation and area have been prohibited and have been used this worker's method and this class material now.
2, the roasting method of spray
The roasting method of spray generally is used for the construction of polymers modified asphalt waterproof sheet (volume) material, during construction, fill gasoline with blowtorch,, with flame alignment tab (volume) material the polyethylene film on the sheet material is burnt with the way of flame, and with the asphalt melting on sheet (volume) the material watertight composition, the basic unit that sheet (volume) material is pasted waterproofing work gets on while hot, repeat this kind worker method, the front and back construction surface is connected, finish the construction task of whole waterproofing work.The advantage of this worker's method is that technology is fairly simple, and the workman grasps easily, therefore remains main construction in the construction waterproofing engineering now.Its shortcoming is: (1) danger.Dress is gasoline in the blowtorch, sets off an explosion easily and fire, and the workman is damaged, and this type of accident takes place a lot of, has caused many heavy losses.(2) damage sheet material.The flame of blowtorch is directly injected on the watertight composition of sheet material sheet material has been burnt out during construction.The also significant points of engineering waterproofing (as places such as corner, gutters) of complex region in the engineering, the workman also just roasts sheet material more severe for sheet attaching is gone to basal plane, and the damage that sheet material is subjected to is also more severe.Therefore, the quality of waterproofing work is also just had a greatly reduced quality.But up to the present, because also do not find gratifying waterproof sheet and supporting construction, so this type of sheet (volume) material, this kind worker method still account for the leading position of waterproofing work.
Two, cold worker's method
Cold worker's method comprises three types of cold mounting methods, self-adhesion method, mechanical Fixing Method.
1, cold mounting method
Polymer rubber flashing (volume) material such as EPDM waterproof roll, haloflex coiled material etc., worker's method construction of all adopting cold bonding to paste, during construction, elder generation's adhesive on the basal plane upper berth of construction waterproofing engineering, again with the paving of sheet (volume) material to adhesive, repeat this kind worker method the front and back construction surface connected, finish the construction task of whole waterproofing work.
Polymer rubber flashing (volume) material itself quality in whole flashing (volume) material is the whole optimal material in flashing (volume) material of going up, it not only has the deformability of enough adaptation engineerings, and ageing-resistant also be best, but because construction quality often can not get guaranteeing, had a strong impact on the waterproof quality of engineering, therefore, the use amount of this type of sheet (volume) material sharply descends in recent years.
The reason that the rubber sheet construction quality can not get guaranteeing has following three aspects: sheet rubber (volume) the material surface on (1) present market is shiny surface, therefore, is difficult to paste firm and solid.(2) for anti-aging, several pieces (volume) materials (as EPDM rubber rolling material etc.) have been selected the material of the molecular structure relative saturation of rubber mostly, thus with the intermiscibility of adhesive also relative mistake some, influenced sticking effect.(3) the strong benzene class flux of the most of selective etchings of adhesive on the present market, and the adhesive that contains benzene is the product of building site forbidding, also be not to be subjected to construct the product that the workman welcomes, based on the reason of above three aspects, cause the development of rubber waterproof sheet material to be contained.
2, self-adhesion method
The self-adhesion method refers to that sheet (volume) material itself carries tack coat, tear the barrier paper (film) that is attached on the tack coat during construction, the basal plane that coiled material is directly pasted waterproofing work gets on, and repeats this kind worker method, the front and back construction surface is connected, finish the construction task of waterproofing work with such method.
The self-adhesion method can realize cold worker's method; non-exhaust emission; protected building site environment and construction workman's personal safety; so development in recent years gets very fast; but also have following weakness: (1) worker's method is difficult for grasping; during construction, careless slightly subsides askew (such situation often has generation) want to take off heavily shop, and coiled material has been out of shape.(2) low temperature can not be constructed, and construction below 10 ℃ just has been a problem, and can not paste.(3) (film) is a kind of waste at the bottom of the isolation that tears it down, and made many construction rubbish again.
3, mechanical Fixing Method
