According to the present invention, the SBS modified asphalt self-adhesion waterproof material has excellent comprehensive economic and technical performance indicators such as excellent water resistance, leakage resistance, weather resistance, high tensile strength, high elongation, aging resistance, good low temperature resistance, strong deformation adaptability, wide adaptation temperature range, high binding strength, long service life, easy construction, low cost and the like, can be used for construction in winter low-temperature regions, and can further be used for highway bridge concrete, subways, railways, ports, large underground engineering and other waterproof projects.
Description
Technical field
The invention belongs to water-proof material preparation field, be specifically related to a kind of SBS modifying asphalt Self-adhesive waterproof material and preparation method thereof.
Background technology
SBS is a kind of synthetic elastomer having plastics and rubber property concurrently, possesses the snappiness of rubber and the high strength of plastics and workability simultaneously, has good lower temperature resistance, ventilation property and anti-slippery, be easy to machine-shaping, add man-hour technique simple, without the need to sulfuration, energy consumption is low, easily painted.
Epoxy resin is the organic high molecular compound containing two or more epoxide groups in general reference molecule, its molecular structure is to contain active oxy radical in molecular chain for its feature, epoxy group can be positioned at the end of molecular chain, centre or structure circlewise, due in molecular structure containing active epoxy group, make they can with polytype solidifying agent generation crosslinking reaction and formed and insoluble, not molten there is the cancellated superpolymer of three-dimensional.
Along with the fast development that highway in China is built, a large amount of makings of high-grade highway, the construction of Large Span Bridges, makes the use of road bitumen material more and more seem important and general.Because pitch tensile strength is low, elongation is little, adhesive property is poor, poor heat resistance, ageing-resistant difference, poor durability etc., and easily to environment.The invention provides a kind of high strength, cohesiveness be high, SBS modifying asphalt Self-adhesive waterproof material that good endurance, resistance to low temperature are good.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art and shortcoming (as: tensile strength is low, elongation is low, not ageing-resistant, non-refractory, adhesive property are poor, resistance to low temperature is poor), a kind of novel high strength SBS modified asphalt waterproof material is provided, this water-proof material has good ageing resistance, cohesiveness, high strength, feature that resistance to low temperature is good, and there is autohension, convenient construction.
The present invention is achieved by following technical proposals:

The preparation method of modified epoxy waterproof sheet of the present invention, by above-mentioned all raw materials by formula rate requirement, puts in high-speed mixer after weighing and mixes, make the compound of epoxy resin waterproof sheet; The material mixed is added to temperature in twin screw extruder to control, at 120 DEG C ~ 150 DEG C, to carry out granulation.By the material of granulation, be added to the extruder barrel of the extrusion calendaring unit of heating, barrel temperature is 130 DEG C ~ 155 DEG C, become the sheet of melting in rack-style die lip head, the core temperature of mould is 150 DEG C ~ 165 DEG C, then enters tri-roll press machine calendering, and hot compress is unified layer urethane self-adhesive, is rolled into the thin slice of required thickness, through cutting off into the sheet of requirement width, and through tractor traction, be cut into the volume requiring length, make SBS modifying asphalt Self-adhesive waterproof material.
Present inventor carefully studies and analyzes current construction technology, adopts current waterproof roll, owing to there is following shortcoming: 1, tensile strength is low, and elongation is little, poor performance.2, when construction temperature is higher, especially construction in summer, coiled material is yielding.3, the waterproof of waterproof roll, antiseep, weathering resistance, weather resistance, the poor performance such as ageing-resistant, propose the method solving this new difficult problem.
The present invention has carried out tentative research to the design of raw-materially to select, filling a prescription.Epoxy resin, petroleum pitch, SBS, auxiliary agent, weighting agent and filler etc. are selected to be raw material, through twin screw extruder extruding pelletization and extrude the thin slice that three-roller calendaring unit is rolled into required thickness, through cutting off into the sheet of requirement width, and be cut into through tractor traction the volume requiring length, make modified epoxy waterproof sheet.
In the design of selecting, filling a prescription of material, invention has been series of experiments, comprising: the consumption of (1), set collar epoxy resins, SBS and auxiliary agent, the consumption changing petroleum pitch carries out extrusion calendaring experiment, test performance data.(2), the consumption of anchor stone oily bitumen and auxiliary agent, change the consumption of epoxy resin, SBS, carry out extrusion calendaring experiment, test performance data.(3), in order to reduce costs, the present invention adopts light active calcium carbonate weighting agent to carry out extrusion calendaring experiment, and test performance data obtain the formula of cost performance the best.
The feature of epoxy resin waterproof sheet of the present invention: have that excellent waterproof, antiseep, weathering resistance, high tensile, high-elongation, frictional coefficient are large, distortion strong adaptability, thermal adaptation wide ranges, easy to use, the life-span long, easily construction and many excellent combination economy, the technical performance index such as cost is low.
