Abstract
The utility model relates to a reinforced wood plastic compound section which is characterized in comprising a section body(1) and reinforced bars(2), wherein, the reinforced bars(2) are a plurality of fiber beams consisting of glass fiber or aramid fiber. Adhesive is filled in the joints of the fiber beams. The external surface of each fiber beam is coated by adhesive as well. The utility model reserves the properties of wood texture and feel, acceptance of nail inserting and planning as well as resistance against mildew and rot, and the ut9lity model has the advantages of good resistance to creep deformation and warp and stable size. What is more important, the utility model has stronger flexure strength and anti-impact strength. Combining both rigidity and flexibility, the utility model can replace natural wood to be used for stressed structures.
Description
Technical field
The utility model relates to wood plastic composite, especially relates to the Wood-plastic composite section bar of industrial fiber as a kind of enhancing of strength bar.
Background technique
Proposition along with recycling economy, wood plastic composite is subjected to people's pay attention to day by day as biomass energy and environment-friendly material, be familiar with by each fields such as logistics, building materials, decorations, outdoor scene and office accommodation and furniture just at a terrific speed and use, thought one of emerging industry with the fastest developing speed both at home and abroad.Though the physical and chemical performance of wood plastic composite itself has tangible controllability, compare with other structural material, still there is obviously deficiency, mainly be that resistance to flexure is lower, there are creep and buckling deformation problem.This has just determined these common wood plastic composites can only be used for non-structure material at present, can not be applied to the place of stressed structure.
The model utility content
The purpose of this utility model provides a kind of Wood-plastic composite section bar of enhancing, keep wooden wood sense, can follow closely can dig, in the fungus-proof antisepsis, have in light weight, not creep, the advantage of warpage, dimensionally stable not, the most important thing is to have higher resistance to flexure and impact strength, rigidity and toughness are had concurrently, can replace natural high-quality timber fully and be used for stressed structure occasion.
The purpose of this utility model reaches by the following method.The utility model is a kind of Wood-plastic composite section bar of enhancing, it is characterized in that: comprise the material body and the stiffening rib of section bar, have stiffening rib in the material body of described section bar.
Described stiffening rib is the fiber tuft that is made of some glass fibres or aramid fibre by comprising, is filled with tackiness agent in the slit between some fibers, and is coated with tackiness agent at the outer surface of fiber tuft and makes.
On the surface of the tackiness agent outside described fiber tuft, also be stained with silica sand.Or on the surface of the tackiness agent outside fiber tuft, with sandblast that its dozen is coarse, to increase combination force.
Described tackiness agent comprises polyester, unsaturated polyester, epoxy resin, polypropylene or polyurethane.
Stiffening rib described in the utility model, be the fiber tuft that will constitute by each fiber by flood in the groove that tackiness agent is housed, pultrusion finishes filling tackiness agent in the slit between each fiber, and be coated with tackiness agent at the outer surface of fiber tuft and make.Glue one deck silica sand in the outer surface spray of stiffening rib then; Or after curing, form coarse surface through sand blast; To strengthen the combination force between this stiffening rib and wood plastic composite interface.This stiffening rib has the tension also higher than reinforcing bar, resistance to flexure, so when stiffening rib and Wood-plastic profiles body have constituted composite material, just formed a kind of Wood-plastic composite section bar of enhancing.
Material body described in the utility model is to be made by known wood powder and plastics, and described wood powder is various vegetable fibers, as wood fiber or grass fibers such as wood chip, bamboo bits, rice husk, stalk, careless classes.Described plastics are polyethylene (PE), polypropylene (PP), PVC (PVC), polyurethane (PU) or various thermoplastics such as polystyrene (PS) and copolymerized blend thereof.Material body with these materials mixing one-tenth Wood-plastic composite section bar in Mixing roll.
Mould complex extruder with stiffening rib and Wood-plastic material coextru-lamination by a wood, become the Wood-plastic profiles of enhancing.
In sum, the Wood-plastic composite section bar that the utility model strengthens keep wooden wood sense, can follow closely can dig, in the fungus-proof antisepsis, have in light weight, not creep, the advantage of warpage, dimensionally stable not, the more important thing is and have higher bending resistance and impact strength, rigidity and toughness have concurrently, can replace natural timber, be used for the occasion of force structure.

Embodiment
Be illustrated in figure 1 as the schematic representation of cross section of floor strip of the wood-plastic composite floor of enhancing, comprise the material body 1 and the stiffening rib 2 of floor strip, in described material body 1, have stiffening rib 2.
Described stiffening rib 2 is by the fiber tuft that comprises that some glass fibres 6 constitute, and is filled with tackiness agent in the slit between some glass fibres 6, and is coated with tackiness agent at the outer surface of fiber tuft.The making method of described stiffening rib 2 be with described fiber tuft by flood in the groove that tackiness agent is housed, pultrusion, make filling tackiness agent in the slit between each glass fibre 6, and be coated with tackiness agent at the outer surface of fiber tuft and make.
Also can on the surface of the tackiness agent outside the stiffening rib 2, be stained with quartz sand layer; Or with fiber tuft dipping, solidify after, the outer surface of stiffening rib 2 is beaten with blasting method coarse, to strengthen in conjunction with dynamics.Described tackiness agent is an epoxy resin.
In the material body 1 among Fig. 1, have 6 stiffening ribs 2.Figure of eight screw installing space 3 and two limit walls have constituted the force structure of two dual-grippers, ailing or screw in screw when installing.Mark among the figure on the dual-side is the line of rabbet joint 4, is to erect when using as joist when present embodiment, and the floor connects ailing when installing with it or screws in the position of screw.The enhancing wood plastic composite of this structure can replacing wood, uses as the material of force structure.
The cross sectional representation that the wood of the enhancing with square-section is moulded composite pillar (or crossbeam) has been shown among Fig. 2.Comprise material body 1 and stiffening rib 2 among the figure; At the place, four angles of material body 1, place, every angle has a stiffening rib 2.Described stiffening rib 2 is by the fiber tuft that comprises that some aramid fibres 7 constitute, be filled with tackiness agent in the slit between some aramid fibres 7, and be coated with tackiness agent at the outer surface of fiber tuft and constitute, be stained with quartz sand layer on the surface of the tackiness agent outside fiber tuft, to increase combination force.Described tackiness agent is a polyurethane.
