DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the detailed description of the embodiments, reference will be made to Fig. 1. The preferred embodiment of the polyacetal wood 2 of the present invention is made by one of a mixture of extrusion molding and injection molding. The polyacetal plastic wood 2 formed by the mixture has a plastic substrate portion 21, and a plurality of wood powder particles 2 2 interspersed with the (four) and surface of the surface portion. The mixture contains 100 parts by weight of the plastic component. , 1〇~ 9 parts by weight of the wood powder component, 2 to 10 parts by weight of the compatibilizer component, and 3 to 2 parts by weight of the modifier component, and the plastic component comprises 5 〇 to 9 〇 wt% a first plastic, and 10 to 50 Wt% of the second plastic, the first plastic is polyethylene terephthalate, and the second plastic is a high molecular polymer selected from the group consisting of: 201141940 ethylene , polypropylene, polystyrene, acrylonitrile butadiene styrene copolymer, polyamine 6 (also known as nylon 6), polyamide 66 (also known as nylon 66), polycarbonate, polymethacrylic acid A combination of a methyl ester, and the like. If the amount of the wood flour component is less than 1 part by weight, the relative cost of the wood-based material is relatively increased, and the resulting wood-like wood feel is poor. Therefore, the amount of the wood flour component is preferably set to be less than 卯 by weight with respect to 1 〇〇 of the straight plastic component. The existing plastic wood prepared by mixing polyethylene or polypropylene with wood powder, because polyethylene and polypropylene belong to hydrocarbon polymer, its structure is composed solely of carbon and hydrogen, and the compatibility with wood powder is relatively poor. The wood-like feel of the plastic wood produced by it is not as good as that of polyester wood. Preferably, in order to avoid affecting the processability of the mixture and to meet the physical property requirements of the prepared polyester wood, the wood powder particle size in the wood powder component is required to be 200# m ^ and can be ground. Make the particle size of the wood powder meet the demand. If the particle size of the wood powder in the wood powder component is too large, the fluidity of the wood powder between the polymers is poor, and the agglomeration phenomenon is easy, so that the mixture is prepared because the wood powder is poorly dispersed. The physical properties of the manufactured plastic wood products deteriorated. The compatibilizer component is selected from the group consisting of epoxy-functional difunctional resins, through which a bifunctional reactive group of the compatibilizer component has a terminal group reactive with the second plastic group, and the primary bond The phenoxy group (Ρ^ηοχγ) is compatible with polyethylene terephthalate, so that at least the polyethylene terephthalate of the first plastic and the second plastic in the plastic component can be A plastic component forms a good compatible effect. In addition, by adding an appropriate proportion of the compatibilizer group 201141940 'can effectively prevent the mold from expanding during extrusion molding' and can reduce the interfacial tension between the first and second plastics and enhance the adhesion of the interface To stabilize the mixture into a form of polyester wood, thereby significantly improving the mechanical properties such as tensile strength, flexural modulus and impact strength of the polyester wood, thereby producing a low-cost and stable quality. Polyester plastic wood. If the total weight of the plastic component is 100 parts by weight, if the amount of the compatibilizer component is less than 2 parts by weight, the compatibility can be affected, if the amount of the compatibilizer component exceeds 10 In parts by weight, the compatibilizer component itself may produce a self-crosslinking reaction' which affects the processability of the mixture. The modifier component is an impact modifier selected according to the required impact strength, and the blending system of the mixture can be toughened by adding an impact modifier to enhance the polyester plastic wood. Impact strength. Preferably, the modifier component may be a reactive core-shell type impact modification formed by a terpolymer of methyl methacrylate, butadiene and styrene. Agent, MBS (methyl methacrylate·butadiene- styrene), MBS is a modifier with a typical core-shell structure. In addition, the modifier component may also be a reactive impact modifier EGMA having the chemical formula (I), and the modifier is a reactive ethylene copolymer, which can also achieve the improvement of the polyester plastic wood. The effect of impact strength. According to the results of the continuous g formula, the plastic component can be obtained with the best physical properties when the amount of the modifier is in the range of 3 to 2 parts by weight relative to the weight of the plastic component. Performance and balance, such as impact resistance, heat distortion temperature, etc. 201141940
