Description

novel environment-friendly flame-retardant wood profile and manufacturing method thereof
Technical Field
The application relates to the technical field of flame-retardant wooden sectional materials, in particular to a novel environment-friendly flame-retardant wooden sectional material, and also relates to a manufacturing method of the flame-retardant wooden sectional material.
Background
The wood material is a natural material, has excellent visual, tactile, auditory and other environmental characteristics, has excellent strength-to-weight ratio and is incomparable with other materials (such as wood plastics, straw shavings, stone materials, metal materials and the like). The wood material is often used for interior decoration of houses, public places and vehicles, and the flame retardant property of the wood material is an important index of wood products.
the fire retardant wood profiles of the prior art generally comprise 3 forms: the first one is to compound the wood material with the physical flame retardant material, such as the wear resistant flame retardant floor disclosed in chinese patent 201120279673.7, which achieves a certain flame retardant effect by bonding the alumina wear resistant paper on the surface of the wood substrate; the second is to perform densification and impregnation treatment on a wood material, such as a compressed flame retardant profile disclosed in chinese patent 201210457197.2, which achieves the flame retardant effect of the wood profile by performing densification treatment on a fast growing wood and then impregnating a chemical flame retardant agent; the third is to dip the wood material into the fire retardant agent, for example, in the fire retardant and wear resistant solid wood composite floor disclosed in chinese patent 200720187592.8, the solid wood material is dipped into the fire retardant agent and then bonded with the alumina wear resistant layer (the alumina particles in the wear resistant layer are mainly used for wear resistance).
For the first flame-retardant section and the flame-retardant method thereof, the flame-retardant effect only depends on the flame-retardant effect of the aluminum oxide wear-resistant paper, the flame-retardant effect is not good if the amount of aluminum oxide of the aluminum oxide wear-resistant paper is insufficient, and the manufacturing cost is too high if the amount of aluminum oxide is sufficient; for the second and third flame-retardant section bars and the flame-retardant method thereof, although various flame-retardant additives can achieve good flame-retardant effect, part of flame-retardant agents can form toxic gas during combustion (namely flame-retardant), so that the risk of fire is improved, meanwhile, the dipping treatment time for dipping the flame-retardant agents is longer, and the drying and curing time after treatment is also relatively longer, so that the production period is long and the production efficiency is low.

Detailed Description
The following examples are given to further illustrate the embodiments of the present invention. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Example 1: referring to the figure, the novel environment-friendly flame-retardant wood profile sequentially comprises a first flame-retardant adhesive layer 200, a base material layer 100 and a second flame-retardant adhesive layer 300 which are bonded with each other from top to bottom, wherein an upper flame-retardant reinforcing layer 110 is formed on an upper layer part of the base material layer 100 in the thickness direction. Wherein, the first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300 are both aluminum oxide adhesive paper. Specifically, the upper flame-retardant reinforced layer 110 of the present application refers to an air-dried density of not less than 1000kg/m3Preferably, its air-dry density is 1000kg/m3-1500kg/m3(e.g., 1200 kg/m)3）。
With the above structure, the novel environment-friendly flame-retardant wood profile of the embodiment utilizes the upper flame-retardant enhancement layer 110 formed on the upper layer (the surface layer and the part below the surface layer) in the thickness direction of the substrate layer 100, so as to form a relatively effective flame-retardant effect by matching the substrate layer 100 with the first flame-retardant adhesive layer and the second flame-retardant adhesive layers 200 and 300, wherein the substrate layer 100 has a relatively high air-drying density; meanwhile, the substrate layer 100 with relatively high air-dry density and the first and second flame-retardant adhesive layers 200 and 300 have physical flame-retardant effects, so that no toxic gas is generated in the combustion process (flame-retardant process), and the flame-retardant effect is relatively safe.
In the present embodiment, the substrate layer 100 is one of a medium/high density fiberboard, a plywood, a three-layer plywood, a shaving board, a solid wood board, a finger-jointed board, and a laminated wood. The thickness of the substrate layer 100 is designed to be 6mm, 8mm, 10mm, 12mm and the like according to the design requirement of a product, and the thickness of the upper flame-retardant reinforcing layer 110 accounts for 5% -10% of the total thickness of the substrate layer 100. Theoretically, the larger the thickness of the upper flame-retardant reinforcing layer 110 is, the better the flame-retardant effect thereof is, that is, the upper flame-retardant reinforcing layer 110 can occupy the whole thickness of the base material layer 100, but from the aspects of production efficiency, material loss rate (material thickness loss), the correspondence between the thickness of the upper flame-retardant base material layer 110 and the flame-retardant effect, and the like, the preferable minimum thickness of the upper flame-retardant reinforcing layer 110 is 5% of the total thickness of the base material layer 100, and the preferable maximum thickness is 10% of the total thickness of the base material layer 100. That is, when the thickness of the substrate layer 100 is 10mm, the thickness of the upper flame-retardant reinforcing layer 110 should be 0.5mm to 1 mm.
The first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300 are melamine stickers added with aluminum oxide particles, and are bonded with the substrate layer 100 through the viscosity of the first flame-retardant adhesive layer after being heated and melted. Preferably, the first flame-retardant coating 200 is a melamine sticker which is added with aluminum oxide particles and has a quantitative weight of 45 grams per square meter, and the second flame-retardant coating is a melamine sticker which is added with aluminum oxide particles and has a quantitative weight of 30 grams per square meter or 33 grams per square meter.
For the convenience of surface decoration, it is preferable that a first wooden skin layer 400 is adhesively provided on the surface of the first flame retardant coating 200 and a second wooden skin layer 500 is adhesively provided on the bottom surface of the second flame retardant coating 300. The surface of the first flame-retardant layer 200 is a surface opposite to the bonding surface to which the substrate layer 100 is bonded, and the bottom surface of the second flame-retardant layer 300 is a surface opposite to the bonding surface to which the substrate layer 100 is bonded. The adhesion between the first wooden skin layer 400 and the second wooden skin layer 500 and the first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300 is realized by the viscosity of the first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300 after heating and melting. In this embodiment, the first and second wood skin layers 400 and 500 are rotary-cut wood skins having a thickness of 0.3mm to 0.5mm (preferably 0.5 mm). The effect of setting up first wooden cortex 400, second wooden cortex 500 is the roughness that improves the surface and the back of this application technical scheme's novel fire-retardant wooden section bar of environmental protection to do benefit to the setting of decorative cover.
When this application technical scheme's novel fire-retardant wooden section bar of environmental protection is as a novel laminate flooring wallboard, can bond through the surface at first wooden cortex 400 and set up decorative layer 600, bond at the bottom surface of second wooden cortex 500 and set up balanced layer 700 and realize. The decorative layer 600 is a decorative layer including decorative paper and wear-resistant paper, and the balance layer 700 is melamine balance paper in the prior art.
when this application technical scheme's novel fire-retardant wooden section bar of environmental protection is as a novel laminate flooring wallboard, can bond through the surface at first wooden cortex 400 and set up decorative layer 600, bond at the bottom surface of second wooden cortex 500 and set up balanced layer 700 and realize. The decorative layer 600 is a veneer made by rotary cutting or slicing, and has a thickness of 0.2mm-6mm, and the balance layer 700 is a rotary cut veneer with a thickness of 0.2mm-0.5 mm.
In particular, a heat dissipation layer 800 may also be disposed on top of the decoration layer 600, the heat dissipation layer 800 being a metal coating. The heat dissipation layer 800 may be a metal spray coating, such as a metal spray coating with alumina particles, which is sprayed on the decoration layer 600 through a spraying process. The heat dissipation layer 800 may also be an aluminum oxide sticker, and at this time, the heat dissipation layer 800 is attached on the decoration layer 600 by hot pressing.
The novel environment-friendly flame-retardant wood profile is produced by the following manufacturing method:
s1, a step of processing the base material, in the step of processing the base material, the base material layer 100 is processed by hot pressing, so that the upper flame-retardant reinforced layer 110 is formed on the base material layer 100 at least on the upper layer of the thickness direction of the base material layer, and the air-dried density of the upper flame-retardant reinforced layer 110 is not less than 1000kg/m3；
s2, compounding, wherein in the compounding step, the first flame-retardant adhesive layer 200, the base material layer 100 obtained in the base material processing step and the second flame-retardant adhesive layer 300 are sequentially placed from top to bottom, and the first flame-retardant adhesive layer 200, the base material layer 100 and the second flame-retardant adhesive layer 300 are compounded in a hot pressing mode, wherein the hot pressing temperature is 100-150 ℃.
By means of the manufacturing method, the density of the base material layer is improved through physical hot-pressing treatment, and the first and second flame-retardant adhesive layers 200 and 300 are bonded on the upper surface and the lower surface of the base material layer 100 through the physical hot-pressing treatment, so that the flame-retardant treatment method is a pure physical method, and compared with modification treatment of chemical agents, the method is free of chemical agent addition and pollutant formation, and is relatively environment-friendly. Meanwhile, the chemical agent impregnated flame-retardant treatment method needs longer impregnation treatment time, longer secondary drying and health preservation treatment time, and the manufacturing method of the technical scheme of the application only needs twice hot-pressing treatment, and then the novel environment-friendly flame-retardant wooden section bar of the technical scheme of the application is subjected to timing treatment without drying and health preservation treatment, so that the flame-retardant treatment time is shortened, and therefore, the relatively higher flame-retardant effect is achieved, and the relatively higher production efficiency is achieved.
In the step of treating the substrate, the hot pressing temperature (temperature of the upper hot pressing plate) is 100 ℃ to 150 ℃, the hot pressing pressure is 7.0MPa to 12.0MPa, the hot pressing time is 50s to 400s, the temperature of the lower hot pressing plate is normal temperature, but the temperature of the lower hot pressing plate is about 60 ℃ under the influence of the upper hot pressing plate. As will be known to those skilled in the art, the density and thickness of the upper flame-retardant reinforcing layer 110 can be controlled by controlling the hot-pressing temperature (upper hot-pressing plate temperature), the hot-pressing pressure, and the hot-pressing time. For example, the substrate layer 100 is a composite multilayer plate with a thickness of 10mm, and has an initial water content of 12% -16%:
(1) The hot pressing temperature (the temperature of the upper hot pressing plate) is 100 ℃, the hot pressing pressure is 7.0MPa, the hot pressing time is 50s, and after the step of processing the base material, the upper flame-retardant reinforcing layer 110 with the thickness of about 0.5mm +/-0.5 mm and the density of about 1000kg/m for thin film cultivation is formed on the upper layer of the base material layer 100;
(2) after the step of processing the base material, the upper flame-retardant enhancement layer 110 is formed on the upper substrate layer 100, wherein the hot pressing temperature (the temperature of the upper hot pressing plate) is 150 ℃, the hot pressing pressure is 12.0MPa, the hot pressing time is 400s, and the thickness of the upper flame-retardant enhancement layer is about 1mm +/-0.5 mm, and the density of the upper flame-retardant enhancement layer is about 1500kg/m for +/-50 kg/m;
(3) The hot pressing temperature (temperature of the upper hot pressing plate) is 120 ℃, the hot pressing pressure is 10.0MPa, the hot pressing time is 200s, and after the step of processing the base material, the upper flame-retardant reinforcing layer 110 with the thickness of about 0.8mm +/-0.5 mm and the density of about 1200kg/m for thin film rice and 50kg/m for thin film rice and thin film rice is formed on the upper flame-retardant reinforcing layer 100.
It should be noted that the composite multi-layer board is formed by laminating and compounding the cut-log skin layer and the adhesive, and therefore, in this embodiment, the density of the upper flame-retardant reinforcing layer 110 is the air-dried density with the cut-log skin layer and the adhesive as a whole.
In the compounding step, any one of the pressing and pasting compounding processes in the prior art can be adopted, for example, the hot pressing temperature is 120 ℃, the hot pressing pressure is not applied, and the hot pressing time is 8s-20 s. The compounding step is mainly to make the first and second flame retardant adhesive layers 200,300 melt to form viscosity by hot pressing so as to be adhered to the upper and lower surfaces of the substrate layer 100.
when the novel environment-friendly flame-retardant wood profile is used as a novel reinforced/composite floor/wallboard, in the compounding step, a first wood skin layer 400, a first flame-retardant adhesive layer 200, a substrate layer 100 subjected to the substrate treatment step, a second flame-retardant adhesive layer 300 and a second wood skin layer 500 are sequentially placed from top to bottom, the first wood skin layer 400, the first flame-retardant adhesive layer 200, the substrate layer 100, the second flame-retardant adhesive layer 300 and the second wood skin layer 500 are subjected to hot-pressing compounding, and the hot-pressing compounding process is the same as that described above; then, the decorative layer 600 and the heat dissipation layer 800 are placed on the composite blank, the balance layer 700 is placed under the decorative layer, and the composite process is repeated again.
Example 2: the difference between embodiment 1 and embodiment 2 is that, referring to fig. 2, the substrate layer 100 further includes a core layer 120 and a lower flame-retardant reinforcing layer 130 located below the upper flame-retardant reinforcing layer 110, the core layer 120, and the lower flame-retardant reinforcing layer 130 are naturally connected thickness portions made of the same material, an air-dry density of the lower flame-retardant reinforcing layer 130 is not less than 1000kg/m for cultivation, and an air-dry density of the core layer 120 is not less than 800kg/m for cultivation. Specifically, the dry densities of upper and lower flame-retardant reinforcing layers 110,130 are from 1000kg/m to 1500kg/m, and the dry density of core layer 120 is from 800kg/m to 900 kg/m.
borrow by above-mentioned structure, the fire-retardant wooden section bar of novel environmental protection of this embodiment, it is through forming the fire-retardant enhancement layer 110 in the relatively great upper fire-retardant enhancement layer 110 of density, the relatively less sandwich layer 120 of density, the relatively great lower fire-retardant enhancement layer 130 of density in the thickness direction of substrate layer 100 to compare with the technical scheme of embodiment 1, can realize the fire-retardant technical purpose in the back of the fire-retardant wooden section bar of novel environmental protection. Meanwhile, compared with the technical scheme that only the upper flame-retardant enhancement layer is formed or the substrate layer 100 is integrally processed into the upper flame-retardant enhancement layer, the high-density thickness layer clamps the low-density thickness layer, and is matched with the first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300, so that the flame-retardant effect of the wood section can be greatly improved.
