Abstract
A kind of fibre-reinforced resin covered directional strength structural board, it comprises the substrate of directional strength structural slab, and the glass fabric that substrate surface flooded phenolic resins in the hot pressing then through preliminary treatment (laying flake board) is made.It can be widely used in building, decoration and cement formwork, has outstanding advantages such as performance is excellent, cost is low.
Description
The present invention relates to fibre-reinforced resin covered directional strength structural board and manufacture method thereof and application.
Directional strength structural slab (Orinted Structure Board is called for short OSB) is a kind of novel high-strength wooden structures plate.It is with about 15 centimeter length, 25 centimetres wide, the slicing wood chip of 1 millimeters thick, drying, top sizing and wax, align, scale type layering square crossing mats formation a kind of oriented strand laminate that reshaping hot pressing forms.This is that the glued board layering square crossing veneer of mating formation can be obtained high-intensity principle and is transplanted to the important breakthrough that particieboard is produced, and produces high-intensity improved wood with regard to available low value log (poplar, birch, loose Logs of small diameter) like this.What this plate was brought into use is the wood chip of about 10 centimeter length, the main now wood chip that uses about 15 centimeter length, and its length also has the development trend that prolongs again.Along with the lengthening of wood chip length, the intensity of sheet material also improves constantly, and it is different from particieboard fully and becomes typical high strength laminate material.This is unique structural slab that replaces glued board and solid wood in the wood-base fibre and particle panel material.
But above-mentioned its surface smoothness of directional strength structural slab is poor slightly, and wear resistence is not good, and its elastic modelling quantity and hardness can reach the technical standard of making cement formwork.Surface smoothness and wear resistence and hardness in order to increase substantially the directional strength structural slab the invention provides a kind of fibre-reinforced resin covered directional strength structural board and manufacture method thereof and application.
Above-mentioned purpose of the present invention reaches in the following manner:
A kind of fibre-reinforced resin covered directional strength structural board comprises the substrate of directional strength structural slab, it is characterized in that having by hot-press solidifying in described substrate being laminated with the glass cloth that flooded phenolic resins.
It is characterized in that described substrate surface goes up the putty that one phenol glue mixed wood powder in advance.
It is characterized in that described substrate surface one deck wood wool layer of mating formation in advance.
It is characterized in that at least 1 millimeter of described wood wool bed thickness, at least 1 centimetre of the area of every wood wool

A kind of fibre-reinforced resin covered directional strength structural board is included in the glass fabric that is laminated with resin impregnating on the directional strength structural slab substrate surface, it is characterized in that it mainly is used as the decorative panel or the building fireproof plate of cement formwork, indoor and outdoor.
A kind of preparation method of fibre-reinforced resin covered directional strength structural board is characterized in that comprising:
(1) surface treatment of directional strength structural slab is to flatness ± 75 μ;
(2) glass fabric impregnated phenolic resin, then in 100 °-110 ℃ prebake 1-5 minute; And
(3) glass fabric that will flood phenolic resins is laminated with on the surface of directional strength structural slab, and solidification temperature is that 120 ° of-150 ℃ of hot pressing pressures are 15-25kg/cm
2, about 5-10 of time minute.
It is characterized in that described surface treatment comprises that described substrate surface goes up one phenol glue in advance and mix the putty of wood powder and/or one deck wood wool layer of mating formation in advance on described substrate surface.
It is characterized in that at least 1 millimeter of described wood wool bed thickness, at least 1 centimetre of the area of every wood wool

Advantage of the present invention is that significantly fiberglass overlay film directional strength structural slab its intensity after tested is as shown in table 1 below:
Table 1 strength test result (the pine sheet accounts for 50% poplar sheet and accounts for 50%)
Its abrasion-resistant surface test is seen as cement formwork approximately reusable 20 times from PRELIMINARY RESULTS.Its application performance is better than steel form, and cost only is about half of glued board.Simultaneously, not only surfacing is smooth owing to fibre-reinforced resin covered directional strength structural board of the present invention, and its mechanical strength and physical property have been increased substantially, for example: fire resistance, resistance to elevated temperatures etc., therefore be applicable to the decorative panel of building fireproof plate, indoor and outdoor, be particularly useful for cement formwork, and have extremely significantly economic benefit.
Below, with the present invention is described in further detail in conjunction with the accompanying drawings and embodiments.
Fig. 1 is the cutaway view of fibre-reinforced resin covered directional strength structural board of the present invention.
As shown in Figure 1, fibre-reinforced resin covered directional strength structural board of the present invention is included in directional strength structural slab 1 and constitutes fibre-reinforced resin covered directional strength structural board as laying wood wool layer (about 1 millimeters thick) 3 on the surface of substrate, be laminated with the glass fabric 2 that flooded phenolic resins.The manufacturing of the described fibre-reinforced resin covered directional strength structural board of present embodiment is finished by following steps:
1. the preliminary treatment of directional strength structural slab:
First method-with 10-25 centimeter length, 25 centimetres wide, the slicing wood chip of 1 millimeters thick, drying, top sizing and wax, align, on the poplar that 5 layers of square crossing of scale type are mated formation, birch, wooden undersized log sheet laminate, repave one deck wood wool layer to improve its surface smoothness to ± 75 μ, described every wood wool area is at least 1 centimetre
2, thickness is at least 1 millimeter, and reshaping hot pressing forms base material.
Second method-in directional strength structural slab surface application-Dao phenol glue-Wood flour putty and sanding, to improve its surface smoothness to ± 75 μ.
2. the impregnation process of glass fabric:
With the glass fabric resin impregnating, standby after 100 ℃ of-110 ℃ of prebakes then.
3. the overlay film of directional strength structural slab is handled:
The glass fabric that flooded phenolic resins is laminated with on the surface of the directional strength structural slab of handling with above-mentioned the 1st kind or the 2nd kind of method of phenolic resins applying glue, at 15-25kg/cm
2Pressure, under 120 ° of-150 ℃ of temperature hot-press solidifying 5-10 minute, to form product of the present invention.The purposes of this product is as follows:
1. indoor (adhesive UF phenolic resin glue): indoor senior panel, the substitute of industrial department veneer lumber such as board-like furniture and reassembling type furniture and communication.Interior wall, ceiling, wallboard, floor, decorative sheet, the stressed plate of load-bearing etc.
2. outdoor use (adhesive PF phenolic resin glue): luxurious hotel and paving are decorated.Railroad car interior lining panels such as various senior building finishings, occupy plate and floor.Ship superstructure is various with plate etc.
3. architectural as cement formwork and PLASTIC LAMINATED etc.
The above embodiments only for illustrative purposes, concrete protection domain of the present invention will embody in claims.
