Abstract
The invention relates to a reactive SBS (styrene-butadiene-styrene) modified asphalt and a self-adhesive waterproof coiled material prepared from the same, belonging to the field of waterproof materials. The scheme is as follows: the reactive SBS modified asphalt is prepared from the following components in parts by weight: 45-60 parts of petroleum asphalt, 10-15 parts of maleated SBS rubber, 3-6 parts of ethylene propylene diene monomer, 3-6 parts of coumarone indene resin, 2-4 parts of terpene resin and 20-35 parts of activated calcium carbonate. The maleic-anhydride-grafted SBS rubber can react with active groups in the asphalt to form a powerful three-dimensional network, thereby enhancing the integral strength of the asphalt and improving the high/low-temperature properties and ageing resistance of the asphalt. The self-adhesive waterproof coiled material prepared from the reactive SBS modified asphalt comprises a waterproof layer and a release film layer coated on one side of the waterproof layer, wherein the waterproof layer is a tyre base dipped with the reactive SBS modified asphalt. The waterproof coiled material has high adhesive force with the base layer to be laid, and the coiled materials self-adhere to each other at the overlap joint through the modified asphalt instead of adding adhesive or heating.
Description
Technical field
The invention belongs to field of waterproof materials, relate to a kind of response type SBS rubber chemistry modifying asphalt, also relate to the autohension waterproof roll that utilizes this modifying asphalt preparation simultaneously.
Background technology
Seepage is very serious qualitative problems of construction often by the cancer that is called building of everybody image, and waterproof roll then can bear big hydraulic pressure, is the effective means of prevention leakage problems.But, when adopting common waterproof roll laying construction, in order to strengthen the bounding force between waterproof roll and the buildings basal plane, usually need with the waterproof roll hot melt or on the paved surface of waterproof roll brushing contain the sizing agent of volatile solvent.This constructional method not only endangers the healthy of workman, and the power consumption heat dissipation, wastes man-hour.
Based on the problems referred to above, the researchist has developed the different autohension waterproof roll of numerous characteristics, as the disclosed waterproof roll of CN200610127174.X, CN200610200760.2 is multi-layer combined structure, mainly comprise waterproof base material and self-adhesive layer, be equivalent on the basis of traditional coiled material, set up self-adhesive layer.Though combined type autohension waterproof roll has solved the difficult problem of construction, layer remains the important factor that limits its performance with the consistency of interlayer, the creep property of waterproof base material.By contrast, the autohension water-proof material directly is coated on makes waterproof roll on the tire base and as if more have superiority, what all adopt as CN200410086273.9, CN200910068955.X, CN200710120809.8, CN200710120808.3 is this thinking, and autohension water-proof material wherein mostly is the blend rubber modifying asphalt that is added with tackifier.Though physical blending can improve the bituminous performance to a certain extent, simple mechanical dispersion and parcel can not be covered rubber and bituminous thermodynamics uncompatibility, and both are difficult to form stable system.
Summary of the invention
The objective of the invention is for the good SBS rubber modified asphalt of a kind of viscosity height, consistency being provided and preparing this bituminous method.Utilizing described SBS modifying asphalt to make the autohension waterproof roll then is another object of the present invention, and preparation technology is simple for this waterproof roll, safety non-pollution, and can simplify operational procedure, reduction difficulty of construction.
Based on above-mentioned purpose, the present invention has adopted following technical scheme: response type SBS modifying asphalt, make by the raw material of following weight parts: petroleum pitch 45-60 part, cis-butenedioic anhydride (maleic anhydride) SBS rubber 10-15 part, Ethylene Propylene Terpolymer 3-6 part, coumarone indene resin 3-6 part, terpine resin 2-4 part, treated carbonates 20-35 part.
Cis-butenedioic anhydride percentage of grafting 1-3% in the described cis-butenedioic anhydride SBS rubber.
Above-mentioned each raw material is promptly got described modifying asphalt after mixing under 150-170 ℃.
Utilize the autohension waterproof roll of response type SBS modifying asphalt preparation, comprise waterproof layer and the release thin film layer that overlays on waterproof layer one side, described waterproof layer is the tire base that is impregnated with response type SBS modifying asphalt.
Grafted maleic anhydride on SBS rubber, be equivalent between SBS and pitch, erect a bridge block, cis-butenedioic anhydride can react with active group in the pitch such as the α-H on the aromatic ring, thereby makes between SBS and the pitch with the strong three-dimensional net structure of the form of chemical bond formation crosslinked together.The SBS chemical modified bitumen can improve the bituminous bulk strength, improves its high temperature performance and ageing-resistant performance.Response type SBS modifying asphalt high temperature of the present invention does not trickle, not embrittlement of low temperature, and creep properties is good, and has extremely strong viscosity; Have fabulous bonding force with its waterproof roll made from basic unit to be laid, the lap-joint of coiled material and coiled material leans on the modifying asphalt self-adhesion and need not add tackiness agent in addition or add heat bonding.In addition, the engineering big for hydraulic pressure, that waterproof requirement is high can be compound with two or more the tire bases that are impregnated with modifying asphalt, makes waterproof layer, or carry out paved in multi-layers in construction.
