Description

The production method of green environmental-protecsolid solid wood decorative panel
Technical field
The present invention relates to a kind of fire-resistant decoration plate and preparation method thereof and including the fire proofing of the fire-resistant decoration plate.
Background technology
Expanded polystyrene (EPS)（EPS）It is low with density, specific strength is high, water absorption rate is low, acid and alkali-resistance, sound deadener/insulator are good, protect Warm nature is good, and shockproof, the advantages that can decorating, is easily molded and excellent cost performance make it be grown rapidly, except in buffers packet Dress, food fresh keeping packaging, inside and outside wall thermal insulation, heat-insulated etc. widely apply it is outer, in recent years also building, industrial circle increasingly Seem and attracts people's attention.EPS is its heat preservation, heat-proof quality, its a large amount of use in building in Application in Building contribution outstanding It can be effectively reduced use and the heating energy consumption of air-conditioning, and reduce the discharge of carbon dioxide.EPS is only single use at present In every field, with the change of environment, simple EPS foam heat-insulating boards have occurred easy to crack, easy to fall off and unsightly The problem of, new thermal insulation material is needed to replace EPS thermal insulation materials.Wood-plastic material, due to its have very high fire line, can Plasticity and sound-proofing, have both high-environmental, nuisanceless, pollution-free, recyclable, and alternative color and material it is more and Favored by more and more people.It is substantially stable for the moulding process of insulating plastic pipe at present, but in process of production The problem that there are still some costs is excessively high, condition is harsh, bonding is insecure etc..
When if it is carrying out flame retardant treatment to finished product glued board, the adhesive for being generally employed to produce glued board is phenolic resin Or cyanurotriamide modified urea resin, and gluing oxidant layer has larger impact to the scattering and permeating of fire retardant.If face ply When remaining more fire retardant, product easy tos produce moisture absorption and returns white phenomenon, and subsequent secondary operation can and paint poor performance, if Only to plywood skin veneer flame retardant treatment, expected flame retardant effect is often not achieved, needs to increase aid in treatment or increase to answer Qualifications.
After organic insulation material reaches relevant criterion requirement or increases certain ancillary measure, more it should be emphasized that the entirety of system Fire savety.The evaluation of thermal insulation material fire-protection rating cannot represent system whole fire safety performance or fire occur when Real conditions, the material of certain fire retardant grades is when condition has can vigorous combustion, so we should catch external thermal insulation The emphasis of fire safety problem.The Reaction to fire of only outer heat preservation system entirety is functional, and the make of system is reasonable, Cai Nengbao The fire safety performance of card architectural exterior insulation system is met the requirements, and just has extensive practical significance to engineer application.

Wherein, the dosage of each substance is preferably so that on the basis of the total weight of flame-retarding adhesive, water soluble amino resin Content is 30-70 weight %, and the content of dehydration catalyst is 8-35 weight %, and the content of carbon forming agent is 2-20 weight %, auxiliary The content of auxiliary agent is 2-30 weight %, and the content of water is 0-40 weight %.In the case of further preferably, the dosage of each substance makes It is able on the basis of the total weight of flame-retarding adhesive, the content of water soluble amino resin is 40-60 weight %, dehydration catalyst Content is 10-25 weight %, and the content of carbon forming agent is 5-15 weight %, and the content of adjuvant is 3-20 weight %, and water contains Amount is 0-30 weight %.
According to the present invention, the selection of the type of above-mentioned each component has been described above, and repeats no more herein.
The application method of flame-retarding adhesive of the present invention is to be mixed to get aqueous flame-retarding adhesive with curing agent The mixture is coated on the surface of the material of pending flame retardant treatment by mixture, then will be coated with the flame-retarding adhesive Wood materials assembly and hot-press solidifying.The painting of the mixture of aqueous flame-retarding adhesive and curing agent containing the present invention Cloth amount can be depending on the fire-retardant demand to various different materials, and there is no particular limitation.It in other words, can when unused Directly flame-retarding adhesive provided by the invention will be can be obtained after the mixing of each solid component.
According to the present invention, the mixing of various components can be carried out at the same time and can also carry out step by step, and mixed sequence can't The performance of flame-retarding adhesive to obtaining has an impact, for example, can liquid first be mixed to get for water and water soluble amino resin Water soluble amino resin, then remaining component is uniformly mixed with the water soluble amino resin of the liquid again, or A certain amount of water can also be filled into as needed to meet the needs of coating；After can also directly mixing each component with water It arrives；When in use, the content of water is preferably the 20-30 weight % of the total weight of aqueous flame-retarding adhesive.
There is no particular limitation to mixed temperature and mixed time by the present invention, as long as various components is made to be uniformly mixed i.e.
Can, under preferable case, mixed temperature can be 10-40 DEG C, and the mixed time can be 10-60 minutes.
Flame-retarding adhesive provided by the invention can carry out flame retardant treatment to a variety of materials, especially suitable for wooden material Material, is more applicable for being coated directly onto the surface of single-board materials to carry out flame retardant treatment.
According to the present invention, the blank assemblies include at least one layer of Wooden veneer, and in other words, the blank assemblies can be One layer of Wooden veneer, or multilayer laminated, gluing mutually multilayered wood veneer.
Wherein, the number of plies of the multilayered wood veneer can reach according to the thickness and actual needs of single layer Wooden veneer Flame retardant effect depending on.The thickness of the single layer Wooden veneer is by depending on the wood quality that selects, under normal circumstances, the single layer The thickness of Wooden veneer can be 0.1-5mm, preferably 0.1-1.5mm, further preferably 0.15-1mm.Multilayered wood veneer The number of plies usually can be by 1-30 layers, the preferably 2-20 layers of single layer Wooden veneer is laminated, is bonded to obtain including delta wood The blank assemblies of matter veneer.The Wooden veneer of required thickness can be used that well known to a person skilled in the art various methods to obtain, example Such as, the method for rotary-cut or slicing.The material of the Wooden veneer can be various wood materials, described wooden under preferable case Veneer is coniferous wood or broad-leaved wood, the coniferous wood or broad-leaved wood can and preferably poplar, Eucalyptus, Korean pine, China fir Wood, birch, paulownia, larch.
It is above disclosed to be merely a preferred embodiment of the present invention, the right of the present invention cannot be limited with this certainly Range, therefore according to equivalent variations made by scope of the present invention patent, be still within the scope of the present invention.
