Only dust enters, and after preventing from precipitating because dust is long-time, produces the impetus of expansion joint extruding, eliminates potential risk.
Brief description
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is present invention process schematic flow sheet；
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
As shown in figure 1, Colophonium wood wool board production technology proposed by the present invention, comprise the following steps：
Sorting：Choose diameter >=30mm, ruined and damage by worms≤15% firewood, and impurity in firewood is removed；
Chip：By the firewood chosen, order is sent into chip and is machined as wood chip；
Mill silk：Wood chip is delivered to defibrator process and is machined as the wood fiber；
Defibrator is QM9D defibrator technical parameter project data such as following table：
Table 1 defibrator technical parameter
It is impregnated with：The wood fiber is added in pitch impregnation device, pitch impregnation device weight feed Colophonium simultaneously is stirred mixing,
And keeping the temperature at 150～170 DEG C, pressure is maintained at 0.75～0.9MPa, until both merge is impregnated with the drip obtaining having soaked

Above example is impregnated with the final products that step obtains the Colophonium wood fiber that soaked and forming step obtains carry out
Contrast such as following table, the situation that is wherein impregnated with is characterized by the unsoaked wood fiber and Colophonium miscellaneous block number sum, and product quality is passed through
The molding situation of finished product, perception, feel and taste characterize.
The each embodiment of table 2 is impregnated with step and obtains the final products contrast that the Colophonium wood fiber that soaked and forming step obtain
From table 2, data can be seen that, is impregnated with step, stirring mixing temperature be 150～170 DEG C, pressure be 0.75～
0.9MPa, the wood fiber is 10 with the mass ratio of Colophonium:2.8～3.2, the technological parameter in the range of these and proportioning all can be produced
The osmosis type Colophonium wood wool board of product fine, and it is impregnated with temperature in the range of 150～170 DEG C, temperature is higher, and the situation of being impregnated with is got over
Good, it is impregnated with pressure in 0.75～0.9MPa, pressure is higher, infiltration situation is better, but infiltration situation does not well represent finally
The quality of product because temperature and pressure too high if can affect product final quality it is therefore desirable to infiltration temperature, infiltration
Pressure, the wood fiber and asphalt quality find equilibrium point than between three variables, can produce best osmosis type bituminous wood
Filament plate, can also draw from upper table, and in above-described embodiment, the temperature of stirring mixing is 160 DEG C, and pressure is 0.8MPa, the wood fiber
Mass ratio with Colophonium is 10:When 3, the situation that is not only impregnated with is good, and product quality is preferably also, therefore in actual production process
For optimal infiltration condition and proportioning raw materials.
The product osmosis type Colophonium wood wool board that production method of the present invention is produced simultaneously outer brush last layer Colophonium with wood wool board
Plain asphalt wood wool board compare and have further the advantage that：
1st, use time is longer：Being placed in component can be for a long time using not corrupt, and functional period reaches 20 years.
2nd, there is more preferable elasticity：Capital construction because of the effect not destroyed by the stress of oneself when variation of ambient temperature deforms,
Existing domestic a lot of capital construction, often because materials'use is improper in expansion joint, lead to infrastructure project to occur being risen by the stress of oneself
Open, or elastic properties of materials is not, becomes the impetus on expansion joint both sides, etc. reflation after the entrance with magazines such as dust during contraction
When expansion joint there is no space and spreading crack.
3rd, there is more preferable water proofing property：Certain current can be stoped after mounting to enter component inside by expansion joint, wash away
Capital construction basal layer, leads to capital construction force unbalance the phenomenon such as crack, subside.
4th, it is easier to construct：Osmosis type Colophonium wood wool board has and cuts performance well, and a people can be grasped with cutter
Make, substantially reduce cost of labor and difficulty of construction.
5th, there is dustproof effect：In natural environment, because comparing closely between this product fiber and fiber, can be effectively anti-
Only dust enters, and after preventing from precipitating because dust is long-time, produces the impetus of expansion joint extruding, eliminates potential risk.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
