Description
Technical field
The invention belongs to wood plastic composite field, be specifically related to a kind of with bark of dahurian larch and waste or used plastics wood plastic composite that is raw material and preparation method thereof.
Background technology
Wood plastic composite obtains as the material of excellent property and develops fast.Timber is as integral part important in wood plastic composite, and the demand of timber is also growing with each passing day.The forest reserves of China are limited, along with the enforcement of China's Natural Forest Protection Project, the supply of timber is reducing year by year, price is in continuous increase, and the production cost of Mu Su manufacturing enterprise is also increasing, so, substitute Wood flour filled thermoplastic resin in whole or in part with wooden or non-wood industrial wood waste and produce wood plastic composite, become ideal chose, be not only enterprise and reduce production cost, also for these industrial wood wastes have found the approach of utilization.
Tamarack is one of seeds that China's accumulation is larger, and sawmill and plywood factory all remain a large amount of barks every year, and except a small amount of for making except tannin extract or tackiness agent weighting material, all the other major parts are all thrown away or burnt.About the utilization of bark of dahurian larch, there is the following aspects:
Wood-based plate aspect.The people such as Wang Ge are used for wood-based plate aspect to bark of dahurian larch and have done preliminary exploratory development.Bi Kexin etc. by the macromolecular material such as bark of dahurian larch and polystyrene composite manufacturing lagging material, and reach the requirement of heat-insulating property, but the add-on of bark of dahurian larch is limited, and it is excessive to add, and can affect the heat-insulating property of material and increase the weight of goods.The people such as Ao Yujia are with urea-formaldehyde glue as sizing agent, and compacting tamarack shaving board, MOR is lower, can not be used as the use of load-bearing.Liu Yinan etc. adopt phenolic resin adhesive, have prepared bark plate of larch.Directly use bark of dahurian larch pressed sheet, mechanical property does not reach actual operation requirements.When adding a certain amount of Timber residuals, adopt phenolic glue pressed sheet, mechanical property just can reach the requirement of relevant criterion product, and cost advantage is just not remarkable.
Glue aspect.Yan Zhen etc., by bark of dahurian larch is carried out pyrolysis, obtain pyrolysis oil, replace phenol to prepare Pyrolytic tar-PF resin sizing agent pyrolysis oil part, but stability are not as resol.The people such as Teng Yuhui, by Larch Bark Powder Modified Phenol-Formaldehyde Resin sizing agent, can reduce glue cost 40%.But because adhesive-preparing technology is too loaded down with trivial details, need perfect further.
Other aspects.The supplementary meanss such as people's ultrasonic wave such as Liu Ye extract the pycnogenols in bark of dahurian larch, and extraction rate reached is to 1.0512%.Bark of dahurian larch is prepared biomass oil absorption material by modified method by the people such as Huang Hurun, and this biological material can reuse.The people such as Du Xiao extract bark of dahurian larch with aqueous ethanol, have prepared alcohol soluble red pigment, have higher physicochemical stability and tint permanence well.Can waste residue be produced after but bark of dahurian larch has been extracted effective constituent, can not make full use of.
Bark of dahurian larch is used for wood plastic composite and is not yet seen in report especially for the research of extrusion wood plastic composite.
As Nonrenewable resources plastics from its invention since, gradually become current application material the most widely, according to statistics, its application beyond the application quantity of ferrous materials.But plastics are difficult to degraded, and therefore waste and old plastic resource can cause environmental pollution.In order to solve this difficult problem, avoid the environmental problem that waste or used plastics causes, what waste or used plastics applied research became current social has a large problem.
Summary of the invention
The present invention is using bark of dahurian larch powder Substitute For Partial wood powder as filler, using waste or used plastics as matrix, bark of dahurian larch/wood powder/waste or used plastics matrix material is prepared by twin-screw extrusion mode, not only can reduce wood mould manufacturing cost but also take full advantage of waste or used plastics and be easy to realize continuous seepage, for the utilization of bark of dahurian larch powder and waste or used plastics provides a kind of approach.
In the present invention, a kind of wood plastic composite being raw material with bark of dahurian larch and waste or used plastics is by bark of dahurian larch powder, wood powder, waste or used plastics, maleic anhydride grafted polyethylene (MAPE), paraffin and polyethylene wax are made, wherein every 100 raw material are by 60 ~ 10 parts of bark of dahurian larch powder, 0 ~ 50 part of wood powder, 36 parts of waste or used plastics, 4 parts of maleic anhydride grafted polyethylene (MAPE) compositions, paraffin accounts for bark of dahurian larch powder, wood powder, 1% of high density polyethylene(HDPE) and maleic anhydride grafted polyethylene gross weight, polyethylene wax accounts for bark of dahurian larch powder, wood powder, 1% of high density polyethylene(HDPE) and maleic anhydride grafted polyethylene gross weight, its preparation method carries out in the steps below:
Step one, take bark of dahurian larch powder, wood powder, waste or used plastics, maleic anhydride grafted polyethylene (MAPE), paraffin and polyethylene wax respectively after pour in high-speed mixer, high-speed mixing 3 minutes (object mixes) at temperature is 86 DEG C;
Step 2, then pour granulation in twin screw extruder into;
After step 3, granulation are complete, pulverize, be then placed in single screw extrusion machine after cooling, when single screw extrusion machine arrives the temperature of setting, singe screw rotating speed is 10rpm, extrudes wood plastic composite.
Step 2 prilling temperature sets 7 humidity provinces, and the temperature in 1 district of district to 7 is respectively 145 DEG C, 150 DEG C, 160 DEG C, 168 DEG C, 168 DEG C, 160 DEG C, 150 DEG C, rate of feeding 12 revs/min, twin screw rotating speed 60 revs/min
The temperature of step 3 single screw extrusion machine is set as: 1st district: 145 DEG C, 2nd district: 155 DEG C, 3rd district: 168 DEG C, 4th district: 168 DEG C, head temperature: 5th district (on); 165 DEG C, 6th district (left side): 165 DEG C, 7th district (under): 165 DEG C, 8th district (right side): 165 DEG C (5,6,7 and 8 districts are all head temperatures).
Use in the present invention paraffin and polyethylene wax increase melt in an extruder lubrication increase the water-repellancy of material simultaneously.
Bark of dahurian larch powder is partly or entirely substituted wood powder as filler by the present invention, and using waste or used plastics as matrix, the high-density polyethylene composite material obtaining the mechanical property of product and wood powder is close.
The present invention uses discarded bark of dahurian larch for raw material, using waste or used plastics as matrix, turns waste into wealth, is greatly reduced by cost simultaneously; The commercially available price of wood powder is approximately 1000 yuan/ton, and the commercially available price of bark of dahurian larch powder is approximately 700 yuan/ton.
The color of wood plastic composite is more single, needs by adding the staining agent such as iron oxide red or carbon black and make it demonstrate redness or black presenting decorative effect.Bark of dahurian larch powder itself takes on a red color, and employs bark of dahurian larch powder in raw material of the present invention, and after pyroprocess process in expressing technique, high-density polyethylene composite material color is close to the even darker color of rust.Because not using staining agent, therefore cost reduction also add decorative effect simultaneously.
Preparation method of the present invention has easy and simple to handle, and product easy-formation, has continuous prodution, the higher advantage of efficiency.
