Description
Technical field
The present invention relates to a kind of pultrusion method that is provided with the middle empty stomach composite material section bar on natural bark top layer.
Background technology
Glass fiber reinforced plastic shapes have waterproof, protection against the tide, fire-retardant, high temperature resistant, intensity is high, good heat preservation performance, long service life, characteristics that cost is low, field such as extensive use building, decoration at present.Existing glass fiber reinforced plastic shapes is an intrinsic color, and outward appearance is not attractive in appearance, and is ornamental relatively poor relatively, is unsuitable for high-grade decoration field and uses.And natural bark has appearance looks elegant, simple natural, characteristics that wood grain is various, is comparatively ideal ornament materials.But also there is bad, non-moistureproof, not ageing-resistant, the yielding shortcoming of anti-flammability in natural bark, does not also have natural bark at present in the composite material section bar Application for Field.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, provide a kind of specious, have natural wood grain and texture various naturally, ornamental strong, product specification is high, surfacing, in conjunction with firm, process is simple and sun-proof, anti-aging, the on-deformable pultrusion method that is provided with the middle empty stomach composite material section bar on natural bark top layer.
The present invention is achieved in that and gets natural bark, carries out surface treatment by abrasive finishing method; Natural bark is placed on the operating desk, at the joint gluing of natural bark, natural bark butt joint is bonded together, the natural bark after cementing is cut the suitable width of girth that is cut into preformed section bar decorative cover horizontal spreading, rolling is put on the shelf; Get fiber-like material and do vertical reinforcing material, get felt or fabric and do horizontal reinforcing material, put on the shelf, with felt or fabric, fiber-like material and felt or fabric, natural bark is respectively as the endosexine, intermediate layer and extexine, be evenly distributed in advance by different level from the inside to the outside, to flood through resin storage tank as the fiber-like material in intermediate layer and felt or fabric, in the said resin storage tank resin mixture is housed, carry out shaping with natural bark or with natural bark and felt or fabric intermediate layer the apparatus for shaping that is adjacent simultaneously through being placed on the die frame, make natural bark after shaping, form with preformed in identical curved surface or the shaped face of hollow section decorative cover shape, again with the fiber-like material behind the impregnating resin, felt or fabric intermediate layer and felt or fabric endosexine, natural bark enters the relevant position of preforming mould together, carry out preformed, enter in the heat cure mould through pultrusion, in 50～180 ℃ of scopes, divide three sections warm areas to carry out the heat cure moulding according to different polymer, after natural bark forms desired geomery outward, in the inner outwards extruding respectively of section bar, discharge steam bubble, increase section bar density, in case natural bark is destroyed, again through traction, finished product is made in cutting.
According to the pultrusion method of the above-mentioned middle empty stomach composite material section bar that is provided with natural bark top layer, said resin mixture by according to 0.5～3 part of 100 parts of thermosetting resins, the initator of ratio of weight and number, add and fill 15～40 parts of agent, 2～4 parts of thixotropic agent, 0.2～3 part of coupling agent, 0.3～3 part of lubricant, 0.03～0.1 part in antioxidant, 0.02～0.1 part of light stabilizer, 1.5～4 parts of colouring agents and fire retardant and form for 10～50 parts.
According to the pultrusion method of the above-mentioned middle empty stomach composite material section bar that is provided with natural bark top layer, said natural bark is when bonding, and the joint of adjacent natural bark is adsorbed on the platform, to improve bonding firmness.
According to the pultrusion method of the above-mentioned middle empty stomach composite material section bar that is provided with natural bark top layer, when said natural bark is heating and curing, heating-up temperature 110-130 ℃.
Advantage of the present invention be the middle empty stomach composite material section bar that makes specious, have natural wood grain and texture is various naturally, ornamental strong, product specification is high, process is simple.By a pultrusion method, can make reinforcing materials such as natural bark and fiber-like material, various felt or fabric, depress strong bonded in elevated temperature heat to be integral; Because natural bark longitudinal shear is very low, so just must reach desired geomery by the preformed of cold mould, deliver to the heat cure mould through pultrusion, after making natural bark form desired geomery outward, in the outwards extruding respectively of the inside of heat cure mould, discharge steam bubble, increase section bar density, natural bark can not be destroyed, make the surfacing of middle empty stomach composite material section bar, the difficult drop-off that make; In addition, owing in resin mixture, added the antioxidant of preventing old effect, the light stabilizer that plays the anti-ultraviolet radiation effect, can make natural bark top layer have sun-proof, anti-aging, on-deformable premium properties, overcome the defective of natural bark itself, thus fields such as the building of being widely applicable for, decoration, decoration.
