Technical Field

The invention relates to a fireproof flame-retardant technology, in particular to an environment-friendly efficient smoke-suppression additive type flame retardant for a wood artificial board.

Background

Along with the economic development of China, the living standard of people is improved, the requirements of people on safety, environmental protection and the guarantee of life and property are higher and higher, high-rise buildings are more and more like bamboo shoots in spring after rain, and then, environment-friendly and flame-retardant decorative and decorative materials are more and more!

The production of the flame-retardant plywood on the market at present mainly adopts the process that a single board is put into a vacuum high-pressure tank, firstly, the vacuum pumping is carried out, then, water-soluble flame-retardant liquid is injected, the pressure impregnation is carried out, then, the airing and the drying are carried out, and then, the glue washing, the board arrangement and the hot press molding are carried out; the process is complex, time-consuming and energy-consuming, long in production period and serious in capital overstock, and if rain occurs, the sun-cured board is wetted, so that the drug-loading rate of the soaked single-board flame retardant is reduced, the standard cannot be met, and reworking is required, so that the cost is too high, and the efficiency is low; meanwhile, the soaking type flame retardant is water-soluble and is easy to separate out and volatilize, so that the flame retardant grade is reduced, even the flame retardant grade and the flame retardant effect cannot be achieved, the soaking type flame retardant can corrode metal components due to the salt containing acid radicals, the strength of the components is reduced, and the components are broken.

Disclosure of Invention

Aiming at the situation, the invention aims to provide an environment-friendly and efficient smoke-inhibiting additive type flame retardant for wood-based panels, which is prepared by adopting multiple elements of nitrogen, phosphorus and boron to synergistically prepare the additive type flame retardant, can overcome the defects of the existing soaking type flame retardant, and has the advantages of low production cost, high efficiency, convenience in use, good flame-retarding and smoke-inhibiting effects, no volatilization, no persistence, lasting flame retardance, capability of improving the dry-wet bonding strength of finished panels, wide market prospect and convenience in popularization and use.

The hydroxide compound comprises one or more of magnesium hydroxide, sodium hydroxide, calcium hydroxide, aluminum hydroxide, calcium oxide, ammonium carbonate and ammonium bicarbonate.

The working principle of the invention is as follows: the additive flame retardant is prepared by adopting multiple elements of nitrogen, phosphorus and boron to synergically prepare the additive flame retardant, and mainly comprises three parts: a carbon source, an acid source, and a gas source; the carbon source comprises wood which is a material rich in carbon and carbon-rich polyhydroxy compound flour added during glue mixing, the acid source comprises ammonium phosphate, boric acid and borate, and the gas source comprises urea-formaldehyde resin, melamine, dicyandiamide, ammonium phosphate and the like; the basic process of flame retardance is as follows: firstly, inorganic acid is released from acid source substances at a lower temperature by the flame retardant; ② esterification reaction occurs at the temperature slightly higher than the temperature of releasing acid, and amine in the flame retardant can be used as catalyst of esterification reaction; ③ the flame retardant forms a layer of fused substance before or during the esterification; fourthly, the melted flame retardant is expanded and foamed by the water vapor generated by the reaction and the incombustible gas generated by the gas source; fifthly, when the reaction is nearly finished, the fire retardant is gelled and solidified to finally form a compact porous foam carbon layer, and the carbon layer has the four effects of heat insulation, oxygen insulation, smoke suppression and liquid drop prevention, can effectively reduce fire disasters and reduce the accidents of fire disaster, poison and gas poisoning and death; sixthly, because the macromolecular silane coupling agent is introduced into the flame retardant, the substances of the flame retardant are decomposed by heat, the temperature is increased, the residual quantity of the flame retardant at 600-700 ℃ is greatly increased, the flame retardant substances which are easy to dissolve in water can be coated, so that the flame retardant substances are insoluble or slightly soluble in water, and the flame retardant is sealed in the product, thereby achieving the purposes of no moisture absorption and no moisture absorption of the product.

Compared with the prior art, the invention has the following beneficial effects: the additive fire retardant is prepared by adopting multiple elements of nitrogen, phosphorus and boron to synergically prepare the additive fire retardant, can overcome the defects of the existing soaking fire retardant, adopts a process method of directly gluing the double surfaces of the veneers and combining hot press molding during the production of the plywood, has the advantages of low production cost, high efficiency, convenient use, good fire-retardant and smoke-suppression effect, no volatilization, no persistence, lasting fire retardation, capability of improving the dry-wet bonding strength of the finished board and remarkable economic and social benefits.

The invention is widely suitable for matching use in fireproof and flame-retardant operation.

The present invention will be described in further detail with reference to examples.
