Abstract
The invention discloses a wood-plastic floor processing method which comprises the following steps that: first, wood-plastic material and polymer foam are respectively extruded through an extruder simultaneously, and then the two extruded materials form the floor with the polymer foam material in the middle part and the wood-plastic material on the surface through a forming mold simultaneously. The middle part of the floor processed through the method is provided with the polymer foam material, and the surface thereof is provided with the wood-plastic material; the weight of the polymer foam material is lighter, the template quality can be effectively reduced, the middle part of the floor is solidly filled, so that the floor looks more beautiful; and the wood-plastic material on the surface of the floor can fully ensure the surface hardness and the strength of the floor, and does not affect the use quality of the floor. Therefore, the wood-plastic floor has the advantages of light weight and attractive appearance.
Description
Technical field
The present invention relates to a kind of Wood-plastic floor, particularly a kind of processing method of PVC Wood-plastic floor.
Background technology
(Wood-Plastic Composites WPC) is a class NEW TYPE OF COMPOSITE sheet material material that is surging forward in recent years both at home and abroad to wood plastic composite, and it is by with plastics with wooden powder mixes by a certain percentage after the sheet material shape of hot extrusion molding.Wood plastic composite includes plastics, thereby have modulus of elasticity preferably, in addition, because including fiber and warp fully mix with plastics, thereby have the resistance to compression suitable with hardwood, physical and mechanical properties such as counter-bending, and its durability obviously is better than the normal wood material.The case hardness height generally is 2-5 times of timber, owing to have above-mentioned advantage, therefore is widely used in industries such as building materials, furniture, logistics packaging.
The good rerum natura of floor tool that adopts Wood-plastic material to make, better than wood dimensional stability, can not produce to scab in crack, warpage, thing timber, twill, appearance looks elegant, durable, long service life, easy advantage such as machine-shaping, therefore be widely used.But existing Wood-plastic floor is generally PP, the floor of Wood-plastic materials such as PE, as the Chinese invention patent (patent No.: 200820210589.8) disclosed a kind of Wood-plastic floor, this floor fair all heavier, cost of production is higher, be difficult for carrying, even it is still heavier to be made into its weight of hollow floor, nor attractive in appearance.Therefore how to produce a kind of Wood-plastic floor attractive in appearance, light weight and be a lot of floor manufacturer and need a problem that will solve badly.
Summary of the invention
At above-mentioned the deficiencies in the prior art, it is that froth bed, outside are wooden processing method of moulding layer floor that the technical problem to be solved in the present invention provides a kind of inside, and the floor of this method processing has the characteristics of light weight, appearance looks elegant.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of Wood-plastic floor processing method, it comprises the steps: at first simultaneously Wood-plastic material and high molecular foam material respectively to be pushed through an extruder, make two kinds of materials after the extruding be high molecular foam material in the middle of forming through a stock mould tool simultaneously again, the surface is the floor of Wood-plastic material.
Preferably, described Wood-plastic material comprises: polyvinyl chloride 50-75 weight portion, calcium carbonate activated 15-50 weight portion, wood powder 2-40 weight portion, calcium stearate 0.5-1 weight portion, organic rare 0.9-3 weight portion, blowing agent 0.5-3 weight portion, calcium zinc stabilizer 3-8 weight portion, titanium dioxide 3-6 weight portion, UV agent 0.3-0.8 weight portion, the rare 0.5-2 weight portion of chlorinated polyethylene is when above-mentioned material mixes, at first polyvinyl chloride and calcium carbonate activated are mixed in mixer, mixture with polyvinyl chloride and calcium carbonate activated is heated to 80 ℃ then, and then adds wood powder, calcium stearate, organic rare, blowing agent, calcium zinc stabilizer, titanium dioxide, UV agent and chlorinated polyethylene are rare to be mixed, and sends into extruder after at last the gained mixture being heated to 120 ℃.
Preferably, described high molecular foam material comprises: polyvinyl chloride 75-100 weight portion, calcium carbonate activated 10-30 weight portion, organic rare 1-3 weight portion, blowing agent 1.5-3.5 weight portion, calcium zinc stabilizer 8-15 weight portion, titanium dioxide 0.5-3 weight portion, rare 0.5-2 weight portion of chlorinated polyethylene and an amount of toner, when above-mentioned material mixes, at first polyvinyl chloride and calcium carbonate activated are mixed in mixer, the mixture with polyvinyl chloride and calcium carbonate activated is heated to 80 ℃ then, then add organic rare, blowing agent, calcium zinc stabilizer, titanium dioxide, rare and the toner of chlorinated polyethylene mixes, and sends into extruder after at last the gained mixture being heated to 120 ℃.
Preferably, described wood powder is a 20-150 order powdery, and moisture content is below 8% in the described wood powder.
Preferably, the density of this Wood-plastic floor is controlled between the 0.45-0.7.
Technique scheme has following beneficial effect: be high molecular foam material in the middle of the floor of adopting this method to process, the surface is a Wood-plastic material, the lighter weight of high molecular foam material can effectively reduce the quality of template, interposition real core in floor is filled, seem more attractive in appearance, the Wood-plastic material of floor surface can fully guarantee again the floor case hardness and intensity, can not have influence on the service property (quality) on floor.Therefore this Wood-plastic floor has light weight, advantage attractive in appearance.
Description of drawings
Fig. 1 is the structural representation on embodiment of the invention processing gained floor.
The specific embodiment
