Description
Technical field
The invention belongs to new material technology fields, and in particular to a kind of acrylonitrile modified wood powder enhancing Wood-plastic foam material.
Background technology
PVC wood plastic material belongs to green material, and floor, wall can be processed by extrusion molding mould, injection mould, Die
The households such as plate, door-plate, proximate matter or outdoor products, and benezene material is free of, content of formaldehyde is less than 0.2mg/cm3.By PVC wood plastic
Expect to make product is moisture-proof, waterproof, be easy corruption after capable of solving solid wood board and density board water suction being made moist in moist and more water environments
It the problem of rotten, dilatancy, can be applied in the not applicable environment of classical wood millwork.
But it finds that the composite materials property reduction amplitude prepared is larger in actual processing, leads to the power of composite material
Learn the demand that performance cannot be satisfied market.
Invention content
The purpose of the present invention is for existing problem, provide a kind of acrylonitrile modified wood powder enhancing Wood-plastic foam material
Material.
The present invention is achieved by the following technical solutions：
A kind of acrylonitrile modified wood powder enhances Wood-plastic foam material, contains its quality 40.2-49.3% in the Wood-plastic foam material
Acrylonitrile modified wood powder.
Further, the acrylonitrile modified wood powder preparation method is：

30min obtains wood powder mixed liquor, and the initiator of its quality 0.25% is added to wood powder mixed liquor, after stirring evenly, at 68 DEG C
Heat preservation；
（2）Acrylonitrile and tert-butyl chloro-silicane are pressed 20:After the mixing of 1 mass ratio, 55 DEG C are heated to, keeps the temperature 15min,
Obtain mixture；
（3）Above-mentioned mixture is pressed 1:15 mass ratios are added in wood powder mixed liquor, and the pH values for adjusting reaction system exist
5.5, temperature is adjusted to 86 DEG C, is stirred 2 hours with 120r/min rotating speeds, is then filtered, is cleaned using deionized water,
Vacuum drying to constant weight to get.
Further, the wood powder is eucalyptus wood powder.
Further, the initiator is ammonium peroxide.
Further, the Wood-plastic foam material further includes following parts by weight of component：Modified PVC resin 90, foaming
Agent 1.2, lubricant 0.5, stabilizer 1.3.
Further, the modified PVC resin is crossed using the aromatic functional group with 25 carbon atoms as grafted chain
It is introduced into the main chain of polyvinyl chloride and obtains.
Further, the aromatic functional group of the grafting and the polyvinyl chloride unit molar ratio as main chain are 1.2：45.
Further, the aromatic functional group is benzoyl.
Further, the foaming agent is AC foaming agents.
Further, the lubricant is G60 type lubricants.
The present invention has the following advantages compared with prior art：The present invention by being modified processing to Corvic,
The modified PVC resin for being can be with the increasing of shear rate with acrylonitrile modified wood flour composite material melt apparent viscosity
Add the trend that presentation is decreased obviously, to show " shear shinning " feature, shows typical pseudoplastic fluid behavior.This be because
When increasing for shear rate, between modified PVC resin macromolecular chain partly tangle point be disengaged, tangle a little unlock rate
More than rate is rebuild, point quantity of tangling is reduced, and the relative motion between modified PVC resin macromolecular is more prone to, and causes table
Viscosity is seen also to decrease.On the other hand, when shear rate increases, modified PVC resin molecule segment has little time the receipts that relax
Contracting, and be orientated in flow field, the intermolecular interaction between fluid layer reduces, and flow resistance declines.Stablize to be processed in process
It is greatly enhanced；Pass through the synergistic effect between modified PVC resin and acrylonitrile modified wood powder so that compound
Material interface combination is most strong, and when by outer force effect, interface can make external force Transmit evenly to reinforcing fiber, and external force is made effectively to exist
It is buffered between reinforcing fiber, thus the mechanical property of composite material improves therewith；The present invention is by acrylonitrile to eucalyptus wood
Powder is modified processing, and the selection by acrylonitrile monemer and eucalyptus wood powder is because the present invention is obtained by lot of experiments
Acrylonitrile monemer is best to the modified effect of eucalyptus wood powder, and in modifying process, acrylonitrile monemer is to eucalyptus wood powder surface grafting
Rate can quickly be stablized, and in modifying process, eucalyptus wood powder surface grafting active site is more, so that the activated centre caused
Increase, the wood powder surface property after acrylonitrile modified is significantly improved, with the compatibility between polyvinyl chloride molecule
It is significantly improved, meanwhile, acrylonitrile modified wood powder disperses more uniformly, can effectively improve compound in compound system
The physical mechanical property of material, especially impact strength improvement effect is notable, while can effectively reduce Wood-plastic foam material
Water absorption rate.
