Specific embodiment
The present invention prepares the method for bio-based reinforced filling with black liquid as base material using black liquid, wherein, papermaking
100 parts of black liquor；Reinforcing fiber：2~6 parts；Surfactant：0.2~1 part；Weather resisting agent：0.05~0.5 part；Antioxidant：0.05
~0.5 part；Lubricant：0.2~1 part.For details, reference can be made to table 1.
The method that this hair inventive embodiments prepare bio-based reinforced filling using black liquid, step is as follows：
Step 1, black liquid is taken, using acid-precipitation method, by precipitation, dry, grind to form the lignin of 20~50 μm of particle diameter
Fiber powder filler；
The black liquid is from the black liquids of generation such as manufacture wood pulp, straw pulp, jute pulp, reed pulp, sugarcane slurry, bamboo pulp
One or two blended liquids of one or two or two or more mixed liquors, preferential wood pulp or bamboo pulp.Wherein, wood in black liquid
, 10~50%, preferential content is 20% or so for lignin content.
The recipe list of table 1
Step 2, will lignin fibre, weather resisting agent, antioxidant, lubricant, surfactant input in mix machine, mixing speed
400~800r/min, at the uniform velocity stirs 2~3min；
The weather resisting agent is that light stabilizer is blended compound with ultraviolet absorber, and compound proportion is 3：1~1：3；The light
Stabilizer is N, N '-bis--(2,2,6,6- tetramethyl -4- piperidyls) -1,6- hexamethylene diamines and the chloro- 1,3,5- triazines of 2,4,6- tri-
Polymer, the ultraviolet absorber is 2'- (the 2'- hydroxyl -3'- tert-butyl group -5'- aminomethyl phenyls) -5- chlorobenzotriazoles.Light stabilization
The preferential ratio of ratio of agent and ultraviolet absorber is 1：1.The weather resistance of bio-based reinforced filling can be improved by above-mentioned configuration,
The outdoor use time of extension.
The antioxidant is four [β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol esters and thio-2 acid
The blend of double octadecyls.Wherein, four [β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester and thio two
The ratio of the blend of the double octadecyls of propionic acid is 1:1~1:4, preferential ratio 1：3, so as to improve the resistance to of bio-based reinforced filling
Heat ageing, increases resistance to hot-workability.
The lubricant is the blend of Tissuemat E and ethylene bis stearamide, Tissuemat E and ethylene bis stearamide
Compound proportion be 3：2~6：2, preferential ratio 5：2, to improve the dispersiveness and processing characteristics of bio-based reinforced filling.
The surfactant from silane coupler or silicone oil or titanate coupling agent one or two or three kinds altogether
Mixed liquid.Wherein, prioritizing selection is one or two blended liquids of silane coupler or silicone oil, specific requirement：Kinematic viscosity (25
DEG C) it is 30~100mm2/s, so as to the affinity of bio-based reinforced filling can be improved, it is more easy to combine with organic material, dispersion；Together
When make bio-based reinforced filling surface that there is hydrophobicity.
Step 3, reinforcing fiber put into the blend of step 2,300~600r/min of mixing speed is at the uniform velocity stirred
30~90s.
The reinforcing fiber is from carbon fiber or one or two blends or various mixed of silicon whisker or glass fiber powder
Blend；Preferential carbon fiber, specific requirement：Carbon content >=93%, 0.05~3.0mm of length, 4~7 μm of diameter, intensity >=
3.2GPa。
Empirical value of the present invention is with reference to such as table 2 below：
The empirical value of table 2
| Performance project | Experiment 1 | Experiment 2 | Experiment 3 | Experiment 4 | Experiment 5 |
| 1.049 | 1.094 | 1.117 | 1.170 | 1.168 | |
| Particle diameter (μm) | 20~50 | 7~50 | 7~50 | 7~50 | 7~50 |
| Ash content (%, 700 DEG C/45min) | 15.34 | 25.27 | 30.48 | 39.86 | 40.21 |
| Water absorption rate (%, 25 DEG C/24h) | 5.87 | 2.04 | 1.12 | 1.87 | 1.06 |
As can be seen from Table 2, by adding antioxidant and reinforcing fiber inorganic constituents, content of ashes is to increase, explanation
Material is more difficult to carbonization and decomposition risk reduction, and the heat resistance that can embody material increases.Surfactant is added, and increases life
The hydrophobicity of thing base reinforced filling, water absorption rate declines substantially, on the other hand reduces bio-based reinforced filling hydrolytic breakdown risk,
The heat resistance of material is further enhanced.
