Description

OSB-based heat-insulation composite board suitable for industrial production and preparation method thereof
The technical field is as follows:
the invention relates to the field of building boards, in particular to an OSB-based heat-insulating composite board suitable for industrial production and a preparation method thereof.
Background art:
in the prior art, the panel of the thermal insulation composite board such as an OSB-based light thermal insulation composite board is a wood panel, and the phenolic foam core material is arranged in the middle, so that the panel is directly coated with the water-based adhesive in a manual mode during preparation, particularly, during preparation of a large-size composite board, the manual operation is slow, and before adhesion, moisture contained in the water-based adhesive can permeate into the wood panel, so that the first gluing part and the second gluing part have different water contents, which can cause different stresses on two sides after adhesion and poor dimensional stability.
Specifically, as disclosed in chinese patent application 2015100860996, a method for preparing a phenolic foam sandwich composite board is provided, which comprises applying a phenolic resin adhesive added with a curing agent onto a wood board by means of manual roll coating, and stacking and cold pressing the wood board, the phenolic foam board and the wood board in sequence. Adopt wooden panel's surface to carry out the rubber coating in this patent application, mainly be based on phenolic foam board itself takes off the powder easily and falls the sediment, and easy peeling off phenolic foam surface material and cause the glue spreader to block up when the high viscosity gluing agent roller coat and consider. However, the surface of the wood panel is made of wood fibers or the wood fibers are pressed by an adhesive, so that the surface of the wood panel has strong hydrophilicity, if the wood panel is coated with the adhesive, particularly the aqueous phenolic resin adhesive, a large amount of water permeates into the wood panel before the wood panel is bonded with the phenolic foam board in the manual coating process, particularly, the board with large surface flakes superposed with each other like an oriented strand board has large local roughness, the adhesive applying amount is obviously increased when the wood panel is coated with the adhesive, the production cost is improved, and more formaldehyde residue hazards are brought. And the wooden panel itself is liable to absorb water to cause thickness expansion, resulting in a decrease in mechanical strength and poor dimensional stability. In addition, after the subsequent cold pressing and solidification, moisture is difficult to escape, and the defects of low bonding interface strength, easy peeling and the like are caused.
A method for preparing a phenolic foam sandwich composite board disclosed in Chinese patent application 2015100862313. The method is substantially different from the method in patent application 2015100860996 in that the surface of a wood board is coated with a urea-formaldehyde resin adhesive by adopting a manual roller, then a phenolic resin pre-foaming material is added into a frame mould, two wood boards coated with the adhesive are placed on the upper side and the lower side of the mould, and the sandwich composite board is obtained by hot pressing at 70 ℃ for 20 min. The substantial difference between the preparation method of the phenolic foam sandwich board disclosed in patent application 201510086763.7 and patent application 2015100862313 is that the phenolic foam board is directly placed between wood boards coated with urea-formaldehyde resin adhesive, and the board-sandwiched composite board is obtained by cold pressing for 48 hours. The obvious defects of the method are that the urea-formaldehyde resin adhesive has high moisture content, so that the problems of reduced mechanical strength, poor dimensional stability and the like of the wood board caused by the fact that moisture is easily permeated into the wood board in advance are easily caused; the patent furthermore states that the wood-based board used is one of a fiberboard, a wood veneer board, a particle board, a bamboo-wood composite board or a laminated wood board. The oriented strand board is a high-strength board which is formed by pressing large pieces of wood shavings and arranged in a certain direction, the wood shavings and the wood shavings are mutually overlapped, the surface unevenness is extremely high, the use amount of an adhesive can be obviously increased by gluing a wooden panel, and the formaldehyde risk is increased.
In addition, chinese patent application 2010105999521 discloses such a wood fiber reinforced flame retardant foam composite board and a method for preparing the same. The preparation method is characterized in that a wood fiber reinforced flame-retardant phenolic foam material is prepared, then a wood flat plate is coated with an adhesive in advance, the upper surface and the lower surface of the phenolic foam plate are coated with adhesives, and the adhesives are selected from one of phenolic glue, urea-formaldehyde glue, melamine modified urea-formaldehyde glue, universal glue and white latex; then placing the glued foam between glued wood flat plates, and performing hot-pressing compounding at 120 ℃ for 5-10 min; or adding the phenolic resin pre-foaming material into a double-layer wood flat plate die, and placing the die in a thermostat at 70 ℃ for foaming for 30-60min to obtain the phenolic resin pre-foaming material. The problems of easy sideslip during adhesion, poor dimensional stability, high glue consumption, cost increase and the like also exist.
The invention content is as follows:
the technical problem to be solved by the invention is to provide an OSB-based heat-insulating composite board suitable for industrial production, which is convenient for industrial production by arranging a flexible adhesive carrier, enhances the bonding strength to improve the overall strength of the composite board, can prevent the plates from sideslipping during bonding, reasonably controls the amount of adhesive, and avoids the risk of increasing the formaldehyde content.
The technical scheme provided by the invention is that the OSB-based heat-insulation composite board suitable for industrial production comprises an upper wooden panel, a lower wooden panel, a phenolic aldehyde core board, a flexible thin material and a plurality of adhesive layers, wherein the upper wooden panel and the lower wooden panel are positioned on the upper surface and the lower surface, the phenolic aldehyde core board is positioned between the upper wooden panel and the lower wooden panel, the flexible thin material is respectively positioned between the upper wooden panel and the phenolic aldehyde core board, and the upper surface and the lower surface of the flexible thin material are respectively coated with the adhesive and are attached to the corresponding upper wooden panel, lower wooden panel and phenolic aldehyde core board.
The prepared light heat-insulation composite board has the characteristics of strong surface decoration, good heat-insulation property, energy conservation, environmental protection, light weight, high strength, sound insulation, noise reduction, rapid installation and the like, and can be widely applied to the heat-insulation fields of walls, roofs and the like of buildings and wood-structure houses.
