Abstract
The invention relates to a water-based expansive type heat-insulated flame-retardant smoke-suppression dope for wooden products. The preparation process comprises the following steps: adding 1-10 percent by mass of a dispersing agent into 25-40 percent by mass of modified polyurethane emulsion; under the condition of stirring, adding 5-15 percent by mass of hollow glass powder, 20-35 percent by mass of halogen-free intumescent flame retardant and 0.01-1 percent by mass of defoaming agent, uniformly stirring, then adding 0.1-30 percent by mass of water to adjust to proper viscosity, thus obtaining the water-based expansive type heat-insulated flame-retardant smoke-suppression dope. In the dope, the polyurethane emulsion is used for providing adhesive force and shock resistance of paint film of wooden products; the dope is suitable for quick production, and the efficiency is greatly improved; when a fire happens, the heat insulation effect of the product is good, no poisonous gas or smoke is produced, and good escape conditions are provided for people on the scene of fire.
Description
Technical field
The present invention relates to a kind of water expansion heat-insulating flame-retardant for woodwork and press down cigarette coating and coating process, belong to technical field of buildings.
Background technology
At present, use and the interface of coating are in close relations, and coating is a kind of multicomponent system---resin (base-material), color stuffing, solvent, auxiliary agent.Exist between a lot of interfaces, particularly color stuffing and resin, solvent and have certain interface in system inside; Coating is a kind of work in-process simultaneously, must be coated in workpiece, product, structure, and the effects such as protection, decoration, function just can be provided, and will inevitably have certain interfacial state, has also proposed certain requirement for coating uses.In addition, after construction, there is dry, a curing process at coating, wherein must consider the surface between film (wetting) surface and air, with the appearance of film that guarantees to provide good, prevent the appearance of surface imperfection.
For understanding in technical field of coatings, woodwork itself used is because of the inflammable characteristic of its low ignition point, thereby easy initiation fire.For avoiding this disadvantage, the method adopting is at present mainly in timber, to add fire-retardant liquid medicine or application anti-flaming dope.But existing anti-flaming dope cannot, to the effective thermal insulation protection of wooden product, not have Smoke prevention effect yet, even some fire retardant material can discharge halogen-containing toxic gas in the time decomposing.Meanwhile, existing anti-flaming dope, also cannot meet the Production requirement on streamline.For ensureing and improving sticking power and the shock-resistance of paint film, realize the Production requirement of the fire prevention woodwork on streamline, and woodwork is had to effectively heat insulation and Smoke prevention effect, be necessary to do these technology and improved further.
Summary of the invention
The object of the present invention is to provide a kind of water expansion heat-insulating flame-retardant for woodwork press down cigarette coating so that produce fast have flameproof effect the water expansion heat-insulating flame-retardant for woodwork press down cigarette coating and method.
For achieving the above object, technical solution of the present invention is as follows:
A kind of water expansion heat-insulating flame-retardant for woodwork presses down cigarette coating, its preparation process is: in the modified polyurethane emulsion that is 25%～40% in mass percent, adding mass percent is 1%～10% dispersion agent, under whipped state, adding mass percent is 5%～15% double glazing powder, mass percent is 20%～35% halogen-free expansion fire retardant, mass percent is 0.01%～1% defoamer, after stirring, adding mass percent is 0.1%～30% water, be adjusted to appropriate viscosity, thereby make water expansion heat-insulating flame-retardant and press down cigarette coating.
Preferably, in above-mentioned technological process, described dispersion agent is BYK-192 (byk company chemical products); Described defoamer is byk-022 (byk company chemical products); Described halogen-free expansion fire retardant is zuran-484 (very titanizing limited-liability company product).
The above-mentioned water expansion heat-insulating flame-retardant for woodwork presses down the coating process of cigarette coating, above-mentioned coating to be adopted the modes such as roller coat, spraying (electrostatic spraying), vacuum spraying, showering, dip-coating, spin coating, pumping painting coat on woodwork, after calorifier solidifies, again after follow-up ultraviolet-curing paint coating, solidifying, direct finished product packing on streamline, obtains having the woodwork of flameproof effect.
Advantage of the present invention is: in (1) coating of the present invention, use polyaminoester emulsion, sticking power and the shock-resistance of woodwork paint film is provided; (2) the present invention makes product have fire resistance property woodwork in streamline, is applicable to producing fast, greatly raises the efficiency; (3), in the time of presence of fire, this product good heat-insulation effect, delays or prevents that the intensity of a fire from spreading.This invention coatingsurface temperature is below 400 DEG C, and double glazing can intercept thermal conduction, prevents from timber that steam or other materials raise a dust to cause that coating bursts apart, thereby avoids inner timber contact thermal source.In the time that coatingsurface temperature exceedes 400 DEG C, flame-retardant smoke inhibition coating starts liquefaction, constantly expands, and forms thicker heat-barrier coating.(4) the technology of the present invention adopts the expanding layer of toughness thermofin and constantly generation to carry out trap heat conduction, do not adopt the volatilization absorbing and cooling temperature fire prevention principle of Halogen material, avoid the generation of toxic gas and cigarette, when preventing fire spreading, there is smoke suppressing effect, for personnel in the scene of a fire obtain better escape condition.
