Description
Technical field
The present invention relates to a kind of polyurethane water-proof paint, in particular to a kind of no-solvent type with flame-retardant smoke inhibition effect is double
Component polyurethane waterproof coating.
Background technique
In polyurethane coating be usually polyether polyol reacted with polyisocyanates synthesize polymer, mostly by carbon, hydrogen,
The elements such as oxygen composition, there are flame when inflammable, burning is big, dense smoke, serious drippage have the problems such as toxic gas generation, and are drop
It glues and guarantees application property and additional solvent pollutes the environment in volatilization process after film, be detrimental to health, in use
There are biggish safety and environmental protection hidden danger.With people's awareness of safety be gradually increased and the change of social development demand, have resistance
The research and development for firing the no-solvent type coating of smoke suppressing effect are also increasingly taken seriously.Mechanism is the study found that in each conflagration according to investigations
Scene, the death rate of fire incident Field Force probably in ten a ten thousandths, and among these seventy percent or more the cause of death be by
It makes one to generate poisoning even asphyxia phenomenon in the toxic fumes that scene of fire diffuses, it is most of so as to cause the generation of tragedy
High molecular material can not only decompose in the case of a high temperature, generate toxic gas, while undecomposed solid residue meeting
Flue dust is formed, is diffused in air, is hindered escape, caused great harm to the life security of people.It is hidden in face of these safety
Suffer from, nowadays more effective and widely used fire prevention measure is that have the use of the coating of flame-retardant smoke inhibition.This kind of material it is extensive
It uses, to the injures and deaths for reducing scene of fire personnel, improves the fire safety grade of related places, with particularly important reality meaning
Justice.
Combustion reaction must have 3 conditions: combustible, oxygen and heat source as a kind of chemical reaction, its generation.Only
There are this 3 conditions while setting up and contacting with each other, combustion reaction could occur, and otherwise, burning just cannot occur.Polyurethane coating
In be usually polyether polyol reacted with polyisocyanates synthesize polymer, be made of mostly elements such as carbon, hydrogen, oxygen, it is inflammable.
Therefore three conditions of above-mentioned burning, oxygen and heat source are only fallen, just can reach flameproof effect.The present invention is halogenated using having
The flame-retardant smoke inhibition system of the flame-retardant smoke inhibitions synergist such as phosphorus liquid plasticizing flame retardant and inorganic salts compounding.Halogenated phosphorus flame retardant is
Novel efficient flame-retarding agent plays huge effect in many industries, halogenated phosphorus system and inorganic fire-retarded suppression known to inspection information
Cigarette synergist compositional flame-retardant smoke suppressing effect is excellent.The present invention mainly reaches solvent-free, flame-retardant smoke inhibition effect by the following method: 1.
The fire retardant of addition is colorless and transparent fire retardant liquid, can inhibit the generation of smog, effectively in pyrolytic burning so as to have
Effect reduces smoke density；2. smoke suppressant promotes being cross-linked with each other between polymer molecule to a certain extent, so that porous layer of charcoal is quick
It is formed, reduces the generation of combustible to achieve the purpose that press down cigarette.
Summary of the invention
Existing water-repellent paint is inflammable, shortcoming containing toxic solvent flashing it is an object of the invention to overcoming, and provides one
Kind has the no-solvent type double-composition polyurethane waterproof paint of flame-retardant smoke inhibition effect.Key of the invention is halogenated phosphorus system liquid
The flame-retardant smoke inhibition system of body plasticizing flame retardant and inorganic fire-retarded suppression cigarette synergist compounding introduces double-composition polyurethane waterproof paint
Component B system.Halogenated phosphorus system liquid plasticizing flame retardant can reduce coating system viscosity, avoid additional organic solvent, and its with
Inorganic fire-retarded suppression cigarette synergist compounding, so that coating in the case of a high temperature can substantially without obvious volume change when the coating meets fire
It is flame retardancy gas that a series of physical reaction, which occurs, to absorb a large amount of heat, and decompose the gas generated, can be in air
Imflammable gas generate dilution, while inorganic enamel-like protective layer can be formed on surface after material molten, completely cut off air, make oxygen
It cannot be contacted with by protection substrate, to play fire-retardant effect, and promote the mutual friendship between polymer molecule to a certain extent
Connection reduces the generation of combustible so that porous layer of charcoal is quickly formed to achieve the purpose that press down cigarette.
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
A kind of no-solvent type double-composition polyurethane waterproof paint with flame-retardant smoke inhibition effect, including first, second two-component.Its
Middle component A is mainly the base polyurethane prepolymer for use as prepared by polyether polyol, aliphatic diisocyanate, liquid filler, the invention
