Wherein, in the employed urea-formaldehyde glue step, the urea-formaldehyde glue use amount is wood shavings and impregnated paper over dry gross weight 10% in the partly alternative particieboard production process of described impregnated paper, and the impregnated paper use amount is wood shavings and impregnated paper over dry gross weight 5%～20%.Described oven dry weight is for deducting the material weight behind the moisture in the material.
Wherein, partly substitute in the particieboard production process in the employed urea-formaldehyde glue step at described impregnated paper, the use amount of described urea-formaldehyde glue is 5%～10% of wood shavings and an impregnated paper over dry gross weight, and the use amount of impregnated paper is 20% of wood shavings and an impregnated paper over dry gross weight.
Wherein, in the employed urea-formaldehyde glue step, the use amount of described urea-formaldehyde glue is 5%～10% of a wood shavings oven dry weight in the partly alternative particieboard production process of described impregnated paper, and the use amount of impregnated paper is 20% of a wood shavings oven dry weight.
Wherein, use employed urea-formaldehyde glue in the impregnated paper replacing whole particieboard production process in the described technology, and the use amount of impregnated paper is wood shavings and impregnated paper over dry gross weight 20%.
The specific embodiment
By describing technology contents of the present invention, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment is detailed.
Embodiment 1:
In the test of present embodiment, it is 10% that urea-formaldehyde glue applies fixed ratio, and the dipping waste paper adding proportion of pulverizing is respectively 5%, 10%, 20%, and on-gauge plate does not add dipping waste paper.
All plate tests are all carried out in laboratory.Dipping waste paper adds in the glue mixer after pulverizing with beating crusher, and urea-formaldehyde glue injects with spray gun.
Slab uses a framework manually to mat formation, and specification is 500mm * 500mm.
Adopt Jinan testing machine head factory testing press, hot compression parameters is as follows:
Pressure: 4.5MPa
Temperature: 185 ℃
Time: 4.5min
Thickness: 15mm
Wood shavings and dipping waste paper composite plate main performance index that present embodiment is produced in table 2, have been listed: employing standard: GB/T17657-1999
Table 2
Analyzing These parameters can learn, when dipping waste paper adding proportion is 20%, compares with on-gauge plate, and MOR can improve 14%, and internal bond strength can improve 32%, and these are advantages, and the highest content of formaldehyde also is lower than the standard of E1 level 8mg/100g.
The experimental result of present embodiment confirms:
1, dipping waste paper can mix use with the particieboard raw material by larger amt, and can improve the physical and mechanical property of sheet material.
2, by adding dipping waste paper, it is fully possible reducing particieboard glue consumption.
Embodiment 2
The adding proportion that present embodiment will flood waste paper is set at 20%, and the ratio of urea-formaldehyde glue changes.The adding proportion account form of urea-formaldehyde glue has following two kinds:
1, calculates (wood shavings+dipping waste paper) according to accounting for two kinds of heavy ratios of the total over dry of raw material;
2, only calculate according to the ratio that accounts for over dry wood shavings weight.
The urea-formaldehyde glue resin added of on-gauge plate is respectively 5% and 10%.The sheet material mode of production is consistent with embodiment 1.
Wood shavings and dipping waste paper composite plate main performance index that present embodiment is produced in table three, have been listed: employing standard: GB/T17657-1999
Table 3
* 5% or 10% refer to the two kinds of heavy ratios (wood shavings+dipping waste paper) of the total over dry of raw material that account for
* 5% or 10% refers to the ratio that only accounts for over dry wood shavings weight
By above data, we draw: the dipping waste paper of interpolation 20% has tangible influence to the performance of sheet material, even do not need to apply urea-formaldehyde glue and can produce particieboard yet, and MOR higher (MOR of 15mm on-gauge plate under drying condition be 〉=13Mpa).Add sheet material that 10% urea-formaldehyde glue produces and resin added again and be 10% on-gauge plate comparatively speaking, the MOR basically identical.Under the dipping waste paper situation of interpolation 20%, the urea-formaldehyde glue applied amount is 5% or 10%, and it doesn't matter much for plate intensity.In addition, to calculate be in accounting for the heavy ratio (wood shavings+dipping waste paper) of two kinds of total over dry of raw material or only account for the ratio of over dry wood shavings weight, also not mattering much to resin added.Each test sample plate, internal bond strength all are higher than standard value (0.35Mpa).
Each physical and mechanical property index is calculated and is carried out with reference to each relevant criterion (GB4897-2003, GB/T17657-1999).
When adding dipping waste paper and urea-formaldehyde glue simultaneously, although free formaldehyde content increases, maximum 7.25mg/100g still is lower than the standard of E1 level limit value 8mg/100g.
According to the timber intensity testing result, can assert, when dipping waste paper addition is 20%, even also can produce qualified particieboard without urea-formaldehyde glue.High strength more if desired just can reach the equal performance index level that resin added is 10% on-gauge plate fully as long as add 5% urea-formaldehyde glue again.
This method is a kind of good approach of digestion impregnated paper waste material.If dipping waste paper quantity allows, by adding, urea-formaldehyde glue applies ratio can be reduced fully.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent flow process conversion that utilizes description of the present invention to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
