Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of high ferro flame-resistant polyurethane waterproof coating and preparation side thereof
Method.
Background technology
High-speed railway is called for short " high ferro ", refers to, by transforming original circuit (linearization(-sation), gauge standardization), make the highest operation
Speed reaches not less than 200 kilometers per hour, or builds new " the newest line " specially, makes operation speed reach the most extremely
The railway system of few 250 kilometers.
Waterproof material mainly has three classes: waterproof roll, polyurethane waterproof material, new polymers cement group water-proofing material.
It is wet that waterproof material is primarily used to prevent in rainwater, subsoil water, industrial and civilian plumbing, corrosive liquids and air
Gas, steam etc. invade building.
Railway line is mainly made up of roadbed, bridge and tunnel, and due to high ferro, the operation characteristic of Line for Passenger Transportation, the line is busy for bridge
Road ratio is significantly increased, more than 50%.Waterproof layer is set at bridge concrete bridge floor, can effectively intercept water and penetrate into floorings
In structure, slow down steel bar corrosion in the aging of concrete and floorings, thus reach to improve the mesh of concrete bridge structure durability
's.So bridge deck water-proof is an important component part in concrete-bridge engineering, current high ferro water-repellent paint modulus and
Elasticity can not be taken into account.
Existing high ferro polyurethane water-proof paint, because hot strength needs, it is generally two component polyurethane, is divided into first
Component and second component, in use need to mix first, second component according to a certain percentage, could use after stirring.
General first component is base polyurethane prepolymer for use as, and second component is curing system.Because bi-component high ferro polyurethane water-proof paint is being executed
There is burden process before work, so being susceptible to measure mistake, causing waterproof coating physical property and waterproof effect to reduce；Coating
Whipping process easily bubbles, makes easily to occur in the middle of waterproof coating dark bubble, pin hole, affect outward appearance and waterproof effect；First, second group
Dividing after stirring, it is necessary to make to be finished material within its hardening time, otherwise material can make viscosity rise, after retrogradation because of reaction
Cannot scratch or roller coat.
The invention provides a kind of high ferro flame-resistant polyurethane waterproof coating, there is the effect waterproof, fire-retardant, antibacterial of excellence
Really.
