Description
Technical field
The present invention relates to a kind of timber floor production method, be specifically related to the production method of wood-plastic composite floor.
Background technology
Wood plastic composite is to be raw material with plastics and wood fibre, is desirable wood substitutes, is the ideal material that substitutes the family expenses timber floor.The requirement of prediction China's timber in this year is 100,000,000 tons, and quantity delivered only is 6,400 ten thousand tons, and breach is very big, product as an alternative, and wood-plastic composite floor has selling market extremely widely.The making principle of wood-plastic composite floor be with through the plastics handled with through the wood powder (as: fibre of plant stalk, passerby's branch, sawdust, wood shavings etc.) pulverizing, stabilizing agent, coupling agent, lubricant, colouring agent etc. together melting mixing make, extrude cooling forming through extruder then.
As everyone knows, there is a large amount of polar groups on the wood-fibred surface, it is poor to exist bigger interface energy in the wood plastic composite preparation process between hydrophily wood-fibred and the hydrophobic polymer, and both interfaces are difficult to fully merge, thereby wood-fibred can not be uniformly dispersed in polymer.And the aggregate of these wood-fibreds easily causes stress to be concentrated under the effect of external force, makes behind the moisture that has absorbed air, can produce wood powder in the wood plastic composite resilience, and influence the service property (quality) of wood plastic composite.In order to solve wood plastic composite suction resilience problem, when producing wood plastic composite, the ratio of generally taking to strengthen plastics is improved, but has increased the cost of wood plastic composite thus, makes it be difficult to be extensive use of in some occasions.And the ratio of plastics just more has been not suitable for material as the floor in the increasing wood plastic composite, and the plastics ratio is big more, and elastic properties of materials is more little, and it is big that plasticity becomes, and the floor feel is bad.
Summary of the invention
The purpose of this invention is to provide that a kind of can to produce dimensional stability good, the suction resilience is little, can recycle, be adapted at using in the general indoor environment, simultaneously also can be out of doors or the product that uses in the environment of indoor humidity, and the production method of the wood-plastic composite floor of low production cost.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
The production method of wood-plastic composite floor, it may further comprise the steps:
(1) wood powder is handled: with 200～240 ℃ temperature wood powder is carried out charing and handle, the processing time is 5～15min, obtains modified wood powder;
(2) powder mixes: with modified wood powder 50～70 weight portions and the mixing preplasticizing of molding powder 30～50 weight portions, obtain wood and mould mixed powder;
(3) extrusion modling: the wood that will obtain is moulded mixed powder and is put into extruder, by die head wood is moulded mixed powder and extrudes and be sheet profile, is wood-plastic clad plate;
(4) following process:, and promptly obtain wood-plastic composite floor through row processing with the wood-plastic clad plate cooling and shaping.
Wood powder is because through the wood powder treatment step, make the polar group on wood-fibred surface destroyed, modified wood powder water absorption rate after the processing reduces more than 50%, and then carry out the powder blend step, to reduce the suction resilience of wood plastic composite, reduce the plastics ratio thereby reach, reduce product cost, the purpose of improving the quality of products.Because the interface energy difference that exists between hydrophily wood-fibred and the hydrophobic polymer is eliminated, the water absorption rate of wood powder is very low, merge fully at both interfaces, stress is also disperseed, so the wood-plastic composite floor that the method makes has very strong anticorrosion moistureproof ability, counter-bending, stretch-proof, impact strength are good, can use in being adapted at general indoor environment, also can use out of doors or in the environment of indoor humidity simultaneously.The suitability for secondary processing of wood-plastic composite floor is good, has timber processing characteristicies such as can sawing, can follow closely, can bore, can dig.
As preferably, in the described wood powder treatment step, the charing treatment temperature is 220～230 ℃, and the processing time is 8～10min.
In the described wood powder treatment step, the moisture content of the modified wood powder that obtains after the processing is 4%～8%.
As preferably, in the described wood powder treatment step, described wood powder is one or more the mixture in timber machining chips, agricultural crop straw powder, cornstarch, the bamboo powder.
As preferably, in the described powder blend step, described molding powder is one or more the mixed-powder among PVC, PE, PP, ABS, the PA.
In the described extrusion modling step, described extruder barrel temperature is 135～150 ℃, and head temperature is 125～135 ℃, extruder pressure 5～8MP.
As preferably, in the described subsequent process steps, described cooling and shaping is the nature cooling.
In the described subsequent process steps, described post-production comprises sanding, fluting, polishes, waxes, paints.
In the described wood powder treatment step, carbonizing treatment method is exactly to place wood powder 200 ℃～240 ℃ duct type charing equipment to carry out pyrolysis processing.
In sum, the present invention has following beneficial effect:
1, wood powder of the present invention is because through the wood powder treatment step, make the polar group on wood-fibred surface destroyed, modified wood powder water absorption rate after the processing reduces more than 50%, and then carry out the powder blend step, to reduce the suction resilience of wood plastic composite, reduce the plastics ratio thereby reach, reduce product cost, the purpose of improving the quality of products;
2, the present invention is owing to the interface energy difference that exists between hydrophily wood-fibred and the hydrophobic polymer is eliminated, the water absorption rate of wood powder is very low, merge fully at both interfaces, stress is also disperseed, so the wood-plastic composite floor that the method makes has very strong anticorrosion moistureproof ability, counter-bending, stretch-proof, impact strength are good, can use in being adapted at general indoor environment, also can use out of doors or in the environment of indoor humidity simultaneously;
The suitability for secondary processing of the wood-plastic composite floor that 3, the present invention produced is good, has timber processing characteristicies such as can sawing, can follow closely, can bore, can dig.
