Description

A kind of waterproof roll and preparation method thereof
Technical field
The invention belongs to architectural waterproof material technical fields, and in particular to a kind of waterproof roll and preparation method thereof.
Background technique
With the development of economy with the progress in epoch, the requirement to construction material is higher and higher, and original construction material is It is not able to satisfy the demand of era development.Many buildings are all to reduce service life because of the erosion of water.With people couple The requirement of building service life is higher and higher, and requirement of the people to waterproof material quality is increasingly paid attention to.Waterproof roll is to build Build common a kind of construction material in construction, road and bridge, roof or need waterproof the construction of building in, be required to pre- First paved waterproof roll.In the production process of waterproof roll, the adhesion of waterproof roll will use isolation film in order to prevent, in order to make Isolation film and waterproof roll can be bonded together, it will usually first its surface be laid with cementing layer, isolated material by cementing layer with Waterproof material combines, and reaches isolation effect.The most commonly used is PET(polyester) film, on the one hand, waterproof roll must in construction Isolated material must be removed before casting concrete, and the isolation film removed can not be used again, and both increases apply in this way Workload, also not environmentally；On the other hand, cementing layer is easy aging, will affect the combination effect of waterproof layer and concrete, is unfavorable for The holding of waterproof effect, and in the construction process, as isolation film is stripped, exposed cementing layer can glue foot, influence construction effect Rate.
There is a kind of adhesive waterproof coil in the market, but coiled material mainly includes waterproof substrate and self-adhesive layer, is equivalent in tradition Self-adhesive layer is additionally arranged on the basis of coiled material.Although combined type self-adhesive waterproof roll material solves the problems, such as that construction is difficult, but layer and layer Between compatibility, the croop property of waterproof substrate be still an important factor for limiting its performance.In contrast, by tack waterproof Material, which is directly coated on, to be made waterproof roll on tire base and seems advantageously.At present also disclose one kind by asphalt, subtract Third fractional oil, thermoplastic styrene butadiene rubber, powder styrene butadiene rubber, coumarone indene resin, Petropols, terpene resin, small-molecular-weight gather different Butylene, ultraviolet absorbing agent, antioxidant, the production of bitumen layer made of calcium carbonate waterproof roll.The waterproof roll uses SBR fourth The preparation of benzene rubber rubber powder, the waterproof roll sizing material is there are loss of properties on aging, the disadvantages of non-refractory.Therefore a kind of property need to be developed The good waterproof roll of energy.
Summary of the invention
The technical problems to be solved by the invention: weather-proof, loss of properties on aging, poor mechanical property for current waterproof roll The problem of, a kind of waterproof roll and preparation method thereof is provided.
