Description
Technical field
The invention belongs to technical field of chemical synthesis, and in particular to a kind of broken stone water permeability pavement poly- ammonia of solvent-free single-component
Ester adhesive and preparation method thereof.
Background technology
The high speed development of modern city, supporting road traffic facility, earth's surface mat formation and manual construction thing increase, composition
The impermeable material of these structures such as cement, pitch, pavement bricks, metal etc. result in track, pavement, parking lot, wide
Often become fluid-tight hard ground, blocked the chance that rainwater penetrates soil so that rainwater fling rivers and creeks or tube and
Ground cannot be looped back, and these road surfaces lack water penetration and gas permeability has intercepted heat, the moisture of atmosphere and rainwash
Circulation, so-called " tropical island effect " is produced to the regulating power of urban surface temperature humidity so as to substantially reduce.
Water-permeable pavement and sub-surface cause the soil that permeated the ground under the water energy on road surface is rapid.Therefore, water penetration road
The laying in face can reduce water logging street, alleviate urban heat land effect.Adhesive is resin type water-permeable brick or the scene permeable road of laying
One of critical material that face makes, what is used at present is generally epoxy resin, phenolic resin, polyurethane etc..And epoxy resin is tough
Property it is poor, impact strength is low, and matter is crisp after solidification, and the color of phenolic resin is relatively deep, have certain fragility, be easily cracked, polyurethane adhesive
Stick possesses excellent shear strength and impact property, and possesses excellent flexible nature, excellent rubber property, can fit
Answer the bonding of different heat expansion coefficient base material, not only bonding force is strong, while also have excellent buffering, shock-absorbing function, low temperature and
Ultralow temperature performance exceedes the adhesive of every other type, it is adaptable to various structural bonding fields.
Chinese patent CN1995257A makees base-material with thermosetting epoxy resin, adds polyamide-based resin, absolute ethyl alcohol, oxygen
Base silane coupling agent, phenol accelerant and 2,4-DTBP, the porous pavement adhesive prepared at room temperature 24 hours
It is curable., with epoxy resin as base-material, fragility is big, and easy to crack, impact resistance is poor for the patent.
Chinese patent CN104004490A adds various functions resin to be prepared for curing rate soon with polyurethane as base material,
The double-component water-permeable brick adhesive such as mechanical property is good, but preparation process is more complicated, in-convenience in use.
The content of the invention
It is an object of the invention to provide a kind of broken stone water permeability pavement solvent-free single-component polyurethane adhesive, with applicable
Phase is long, intensity is high, quick solidifying and be difficult foaming, hardness good-toughness, good base adhesive power, simple to operate, easy construction
And the characteristics of environmental protection；Invention also provides the preparation side of broken stone water permeability pavement solvent-free single-component polyurethane adhesive
Method, it is scientific and reasonable, simple and easy to apply.
