Description
Technical field
The present invention relates to historic building structure fireproofing technique field, in particular to a kind of transparent fireproof coating system and its
Application in wood-structure old building.
Background technique
Ancient building is the rarity of world civilization, has special historical value, cultureal value.Once being caught fire etc. no by appearance
Reversible destruction, loss be it is immeasurable, 2018,2019 occur Brazilian museums and Notre Dame de Paris high fire
Caused loss, it may be said that be the disaster of the whole mankind.China is ancient building historical relic big country, is especially possessed numerous excellent exhausted
Human relations, highly skilled wood-structure old building；In history, it is exactly fire that wood-structure old building, which saves a difficult big reason,.Existing rank
Section fireproof coating is widely used in steel construction, concrete tunnel field, but leads in timber structure field, especially historic building structure
There is also following disadvantages in domain:
(1) poor transparency.Any additional safeguard procedures cannot all influence the aesthetic effect of historic building structure itself, and mesh
Preceding transparent fireproof coating, transparency are generally bad.
(2) environmental suitability is poor.The coating that any one is used in timber outmost surface, it is necessary to have good water-fast, resistance to
The performances such as light aging, resistance to alternation of wetting and drying, just can guarantee long-term effect, and this exactly existing transparent fireproof coating is more difficult overcomes
The problem of.
(3) fire protecting performance is poor.According to test method specified in GB12441-2018 " finishing fire retardant paint ", timber structure
Fire resistant coating is 220 DEG C by areographic pole limit temperature, fire resistance period >=15min, but for wooden structures, 180 DEG C or more timber tables
There is irreversible destruction (charing) in face, and historic building structure category historical relic scarce resource, be impatient at it is any irreversible
Destruction.Obviously, it is excessively high for limiting 220 DEG C of temperature for ancient building by areographic pole, it is therefore necessary to further increase fire prevention
Performance enhances heat insulation.
Summary of the invention
In order to overcome the deficiencies of the prior art, transparency, environmental resistance, the fire protecting performance of timber structure fire resistant coating are improved,
The present invention provides a kind of historic building structure dedicated transparent fire resistant coating system.
Technical scheme is as follows:
A kind of transparent fireproof coating system is made of transparent fire-resisting paint coating and transparent protective coating coating two parts,
Wherein transparent fire-resisting paint coating layer thickness is 0.5-1mm, and overweight coating, the transparency is bad, will affect historic building structure itself
Aesthetic effect, cover light, fire protecting performance be deteriorated；The transparent protective coating coating layer thickness is 0.01-0.02mm.
The transparent fire-resisting paint is made of component A and component B, the component A based on parts by weight, by following component system
At:
10-40 parts of epoxy resin, 10-30 parts of pentaerythrite, 0-40 parts of phosphatase 11,15-30 parts of solvent, 0.5-5 parts of auxiliary agent,
0.5-5 parts of fire-retardant filler.
The component B based on parts by weight, is made of following component: 20-50 parts of melamine, 10-40 parts of urea, and solvent
15-40 parts, 0.5-5 parts of auxiliary agent, 0.5-5 parts of fire-retardant filler, 20-45 parts of formaldehyde.
Wherein, component A and component B be in mass ratio are as follows: and component A: component B=80-100:100-150, it is used after mixing,
Component B dosage is too large or too small, will affect fire protecting performance, and requirement of the invention is not achieved.
Wherein, it is preferred that the epoxy resin is any one or a few in E-03, E-09, E-12, E-20, E-51.
Wherein, it is preferred that the fire-retardant filler is ammonium polyphosphate (degree of polymerization be greater than 1000), aluminium hydroxide, zinc borate, double
Any one or a few in cyanamide etc.；The wherein preferred ammonium polyphosphate of fire-retardant filler in component A, the fire-retardant filler in component B
It is preferred that aluminium hydroxide and dicyandiamide compounding, compound proportion 1:(1-1.5).
Wherein, it is preferred that selected solvent is any one or a few in formaldehyde, ethyl alcohol, ring ethyl ketone, n-butanol etc..
Wherein, it is preferred that selected auxiliary agent is the high-molecular block copolymer wetting and dispersing of the affinity groups of activity containing pigment
Agent, polyester modification dimethyl silicone polymer surface modifier, any one or a few in modified polyurea auxiliary rheological agents.
The preparation method of component A in turn includes the following steps:
(1) epoxy resin is stirred to 20min-40min in cyclohexanone until homogeneous transparent；(2) by pentaerythrite and molten
Agent is added in phosphoric acid, stirring, until sufficiently esterification, coreaction 1h-1.5h；(3) liquid that will be prepared in epoxy resin, step (2)
Body, fire-retardant filler, auxiliary agent mixing, stir 10min-15min, grind into sand mill, fineness≤10 μm, filter, packaging.
The preparation method of component B in turn includes the following steps: (1) melamine, urea, formaldehyde in a solvent stirred,
It is heated to certain temperature, starts synthetic reaction, until homogeneous transparent, 2h-2.5h；(2) step is added in fire-retardant filler, auxiliary agent
(1) the liquid mixing prepared in, stirs 10min-15min, grinds into sand mill, fineness≤10 μm, filter, packaging.
The transparent protective coating coating is historic building structure special protection coating, is one-component coating, with parts by weight
Number meter, is made of following component:
20-40 parts of fluororesin, 0.05-2 parts of coupling agent, 50-70 parts of solvent, 1-10 parts of auxiliary agent.Wherein, it is preferred that described

It is deteriorated, molecular weight is excessively high, and not readily dissolves in a solvent, carries out coating.In addition, although the fluororesin of perfluorocarbon backbone is with excellent
Different hydrophobicity, ageing-resistant performance, but usually molecular-chain polarr is lower, and physical and chemical adsorption ability is poor, and coating is caused to adhere to
Power is bad.Therefore select it is one or more of with fluororesin coupling agent excellent in compatibility, by in transparent fire-resisting paint coating
The mode that active function groups generate chemical bonding improves the adhesive force of transparent protective coating coating and transparent fire-resisting paint coating, thoroughly
The adhesive force of bright protective coating coating and transparent fire-resisting paint coating is too low, will affect coating system overall adhesion of the present invention,
Coating system is easy to fall off, and the adhesive force of transparent protective coating coating and transparent fire-resisting paint coating is excessively high, transparent protective coating
Coating solvents will cause volume contraction when volatilizing, and be easy to influence the adhesive force of transparent fire-resisting paint coating and historic building structure.
Preferably, selected coupling agent is selected from ammonia (amine) hydrocarbyl si lanes coupling agent, epoxyhydrocarbyl silane coupling agent, methacryloxypropyl hydrocarbon
The one or more of base silane coupling agent, these types of coupling agent can satisfy the requirement of coating system adhesive force.
