Abstract
The invention discloses a polyvinyl chloride wood plastic composite plate which is formed by carrying out mixing and granulation on powder materials in a high-speed mixer and then carrying out extrusion in an extruder, wherein the powder materials comprise the following components in parts by weight: 100 parts of polyvinyl chloride resin, 2-4 parts of plasticizer, 35-45 parts of wood fiber, 3.5-4 parts of stabilizer, 1.8-2.3 parts of coupling agent, 0.7-1 part of lubricant, 10-15 parts of foaming agent and 0.5-0.8 part of other auxiliaries. Through the manner, the polyvinyl chloride wood plastic composite plate has the advantages of improving the compatibility and the dispersity between the polyvinyl chloride resin and the wood fiber and improving the tensile strength and the shock strength, and has the properties of resisting light, heat, moisture, corrosion, ageing, climate and the like.
Description
Technical field
The present invention relates to architectural decoration material field, particularly relate to a kind of polyvinyl chloride wood-plastic composite panel.
Background technology
Wood-plastic composite panel because it has the dual nature of timber and plastics, has the advantages such as wear-resisting, dimensional stabilizing, satisfactory mechanical property, is widely used in the industries such as building materials, furniture, logistics packaging.
Existing wood-plastic composite panel, the main polyvinyl chloride (PVC) RESINS that adopts is mutually compound with wood powder, but, because the easy water-absorbent of wood powder and the hydrophobicity of polyvinyl chloride (PVC) RESINS, so that both consistencies are poor, thereby so that the mechanical properties such as the tensile strength of polyvinyl chloride wood-plastic composite panel and shock strength decrease, limited its use in certain fields; On the other hand, existing polyvinyl chloride wood plastic composite easily is subject to the effect such as heat, light, oxygen and occurs agingly in the outdoor application process, affects its work-ing life.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, a kind of polyvinyl chloride wood-plastic composite panel is provided, consistency and dispersiveness between polyvinyl chloride (PVC) RESINS and the wood fibre be can improve, and tensile strength and the resistance to impact shock of polyvinyl chloride wood-plastic composite panel improved.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of polyvinyl chloride wood-plastic composite panel is provided, first with powder blend granulation in high-speed mixer, and then extrusion moulding in forcing machine, described powder comprises by weight than the following composition that forms:
100 parts of polyvinyl chloride (PVC) RESINS,
Softening agent 2-4 part,
Wood fibre 35-45 part,
Stablizer 3.5-4 part,
Coupling agent 1.8-2.3 part,
Lubricant 0.7-1 part,
Whipping agent 10-15 part,
Other auxiliary agents 0.5-0.8 part.
In a preferred embodiment of the present invention, the granularity of described wood fibre is the 70-150 order.
In a preferred embodiment of the present invention, described lubricant is one or more in polyethylene wax, stearic acid, lead stearate, silicone oil, the liquid paraffin.
In a preferred embodiment of the present invention, described other auxiliarys comprise one or more in UV light absorber, dispersion agent, frostproofer, sanitas and the fire retardant.
The invention has the beneficial effects as follows: by scientific and reasonable selection and proportioning, consistency and dispersiveness between polyvinyl chloride (PVC) RESINS and the wood fibre have been improved, and improved tensile strength and the resistance to impact shock of polyvinyl chloride wood-plastic composite panel, make it have the performances such as fast light, heat-resisting, moisture resistance, corrosion-resistant, ageing-resistant and weather.
