Description
Technical field
The invention belongs to buildings waterproof field of material technology is and in particular to a kind of roofing, underground, interior, tunnel etc. are led
Domain uses uncured pure polyurethane water-proof paint and preparation method thereof.
Background technology
In recent years, with the fast development of social economy and urban construction cause, people propose to building waterproof
The high-level requirement of not permeable leak for a long time.And China's leakage of building rate remains high in recent years always, wherein one of the main reasons
It is exactly waterproof layer bonding with what basic unit cannot realize very, once somewhere leak occurs will produce channeling water phenomenon, thus leading
Whole waterproof layer is caused to lose efficacy." channeling water " is always a waterproof difficult problem of people's concern, in order to solve this difficult problem, derives
A kind of with more plastoelastic waterproof material it is simply that uncured (creep properties) waterproof material.
Uncured rubber asphalt waterproof coating in the uncured waterproof material in market, based on pitch, using various bullets
Gonosome, plastics etc. are modified so as to there be certain cohesive force to it, after stress can slip within atarting material thus producing
Plastic deformation, substantially reduces material internal stress.The advantage of uncured rubber asphalt waterproof coating is as follows：Never solidify, construction
After remain gluey；Caking property is strong, can construct in moisture substrate, and can bond with any foreign matter；Pliability is good, elongation percentage
Height, adapts to basic unit's deformation；Self-healing property is strong, though occur during construction waterproof layer breakage also can self-healing, remain complete anti-
Water layer；Can use with other waterproof materials simultaneously, form waterproof system layer, improve waterproof effect, substantially improve " channeling water "
Problem.
But, the uncured rubber asphalt waterproof coating itself commonly used in the market is in sticky glue, and cohesive force is extremely strong,
Directly scrape and smear the method that construction is relatively difficult, therefore mostly melts using heating, high sensitive to temperature using pitch in material
Property, make material have good mobility after supporting firing equipment is heated to uniform temperature, then scratch or spraying application.Logical
Often need scene paint heating to more than 150 DEG C, construct again after material is thinning.Scene heating fusing, produces in work progress
Substantial amounts of bitumen flue gas, not only high energy consumption, to air born pollution, destroy atmospheric environment, and site operation personnel are also deposited
In safety, the impact of health, the requirement to construction equipment is also high.Leverage using and promoting of this kind of product, be current
The problem that the uncured product of pitch class exists.
In addition, also having a kind of uncured water-repellent paint of solvent-borne type pitch in the market, with asphalt as base-material, to have
Decentralized medium made by machine solvent, makees the material modified of pitch using polymer rubber and auxiliary agent, then joins proper amount of adjuvant and make.
This coating relies on lightweight oil solvent to reduce the viscosity of pitch, but solvent load is big, and material solid content is low, meeting after solvent volatilization
Pollution environment, and the volatilization of solvent all can affect the performance of coating with residual, therefore, we believe that the drawbacks of this kind of material very
Many, should not promote.
1) it is to solve channeling water, and asphaltic base uncured high temperature hot melt application problem, Chinese patent CN 1039235655 A
In disclose uncured polyurethane water-proof paint and preparation method thereof, its material be mainly based on asphaltic base, by phase solvent
Base polyurethane prepolymer for use as is mixed with the pitch that modified-high polymer is crossed, the dilution using low viscous performed polymer and compatilizer is made
With, by normal temperature close to solid high viscosity high-polymer modified pitch be diluted to normal temperature can working viscosity；Again will by latent curing agent
Base polyurethane prepolymer for use as film-forming, improving product viscosity, reach a high temperature requirement of not trickling.It is former because it still adopts pitch
Material, using high-polymer modified pitch, and polyurethane prepolymer solidification improves its high-temperature behavior, therefore still there is lacking of environmental protection
Fall into, and strict to packing instructions, meet atmospheric vapourization and can solidify and lead to not normal construction and use.
Content of the invention
It is an object of the invention to provide the uncured polyurethane water-proof paint of cold construction of a kind of asepsis environment-protecting, convenient construction.
It is a further object of the present invention to provide the uncured polyurethane water-proof of cold construction of a kind of process is simple, Environmental Safety applies
Preparation method for material.

PPG and the polyurethane resin of polyisocyanates anamorphic zone terminal hydroxyl, terminal hydroxy group is micro with cement basal plane
The water capacity easily forms hydrogen bond action, increases the cohesive force of coating, and is larger than internal cohesive force, after so that coating is stressed
Fracture mobile layer is inside coating, and has the ability repeatedly boning, and makes basal plane forever be in air-tight state, improves its water proofing property
Can, and modest viscosity, product can directly be uncapped cold construction, need not heat, Environmental Safety.Polyethers in polyurethane resin A is many
First alcohol is made up of polyether Glycols and polyether-tribasic alcohol, and PTMEG can increase chain length, and polyether triol can increase network molecule
Middle connectivity, has the effect knotted, and adds proper amount of polyether-tribasic alcohol in substantial amounts of polyether Glycols, can control net
Volume, reduce hard section and expand soft section to reduce cohesive force, improve elongation percentage.In polar system, resist sagging auxiliary agent can apply
Form tridimensional network, thus providing stronger thixotropy for system, during storage, resist sagging auxiliary agent utilizes three in material system
Each component is held by dimension network structure, effectively stops mobility, during construction, due to the certain shearing force of donor system, resist sagging helps
The network structure of agent is destroyed, and viscosity declines rapidly, can reach working viscosity requirement.After shearing force disappears, this netted knot
Structure just can be set up in several seconds, thus preventing the sagging of paint film.This product based on polyurethane resin, using polyether plasticizer
It is mixed to form creep properties with polyurethane resin, high-temperature behavior is excellent, using material thixotropy Solve problems in construction, environment-protecting asepsis.
