Description
Technical field
The present invention relates to the preparation method of fibre reinforced composites, specifically a kind of preparation method who improves glass-reinforced plastic material.
Background technology
Glass-reinforced plastic material is to be embedded in the cured thermosetting or by it by glass fibre reinforcement to be wrapped to form the material of composite structure.Produce the glass-reinforced plastic material that uses in the market adopts resin infiltration woven fiber glass material to come moulding more.This method effect of impregnation may is good, prepared content of glass fiber height.But owing to be subjected to the restriction of woven fiber glass volume and shape, make its incompatible especially product that is used for being difficult for such as tube stub, tee pipe fitting, bend pipe tools etc. uniform-compression.In addition, its impact resistance of glass-reinforced plastic material of this method preparation is poor, and layering easily takes place laminated face.In order to address the above problem, there is the investigator glass fibre to be cut into the fiber length-to-diameter ratio is about 1000, length is 3 ~ 5mm glass fiber powder, glass fiber powder is put in the mixed solution of being formed by Resins, epoxy, softening agent, silane coupling agent then, in ball mill, stir again and add filler, solidifying agent, be prepared into thus a kind of glass-reinforced plastic material that does not contain woven fiber glass shop layer (see Zhang Juan etc. for details. the preparation of fiber glass epoxy [J] and test. engineering, 2008, NO.13).Though the glass-reinforced plastic material that this method provides has overcome the defective that woven fiber glass itself causes, because glass fibre is cut into powdery, thereby the peculiar physical property of its fiber itself is also weakened greatly.The mode that absorbs striking energy as matrix material usually is to fracture, fiber extraction, 3 kinds of modes of fibre breakage by resin distortion and crack propagation.Be not difficult to find out that thus glass fibre in the matrix material is powdery and embeds in the cured thermosetting, when being subjected to external impacts, the mealiness fiber no longer has when fiber is extracted out and can endergonicly act on, when also having lost fibre breakage simultaneously the energy that can absorb.Also there is the investigator to improve the shock-resistance of glass-reinforced plastic material by the shop layer optimization design that adopts woven fiber glass.As researchists such as Dong Weiwei designed respectively 4 kinds of ply sequences (be respectively 0 °/0 °/0 °/0 °/, 0 °/90 °/0 °/90 °/, 45 °/0 ° of 45 °/﹢ of 0 °/﹢/, 90 ° of 45 °/0 °/-45 °/﹢ of ﹢ /), adopt the vacuum assisted resin injection moulding to carry out compound to glass fibre/unsaturated polyester resin laminated wood.And its impact resistance carried out testing (seeing Dong Weiwei for details, etc. impact resistance research [J] Tianjin University of Technology journal of. glass fibre/unsaturated polyester composite plate, 2008,27 (1) 24-25).Experimental result shows intensity, supporting capacity and the energy absorption capability that adopts 0 °/90 °/0 °/90 °/ply sequence can improve matrix material, but its non-deformability a little less than.The prepared glass reinforced plastic of this method still will be subjected to the restriction of woven fiber glass volume and shape when using in addition.The glass fibre of certain-length sneaked into directly in the thermosetting resin to form a kind of glass-reinforced plastic material that does not contain woven fiber glass shop layer perhaps be a kind of good selection.Yet fiberglass surfacing is smooth, between fiber contact closely, so its dispersiveness is very poor.Therefore when glass fibre is directly sneaked into thermosetting resin, resin is to the non-constant of its wetting property, so glass fibre is difficult to and resin matrix forms firm bonding.In order to improve the adhesive capacity of glass fibre and resin matrix, during many researchists have been placed on research emphasis the surface of glass fibre handled.The method of at present fiberglass surfacing being handled mainly contains: heat treating process, and namely utilize high temperature to make original sizing material oxygenolysis of fiberglass surfacing, remove glass fibre simultaneously owing to storing the water that adsorbs.This method is simple, practical, but its independent result of use is not good enough, thereby the pretreatment process of all handling as fiberglass surfacing usually; Soda acid etching processing method is namely carried out chemical reaction by soda acid at fiberglass surfacing and is formed some depressions or micropore.Treat that glass fibre and matrix carry out compound tense, the segment of some superpolymer enters into the hole. and play similar anchorage effect, increased the bonding force between glass fibre and the polymer interface thus.But studies show that though soda acid etching processing method can effectively increase the surface-area of glass fibre, and improve the wetting property of fiberglass surfacing, but glass fibre to be destroyed by soda acid etching rear surface layer, thereby caused stress concentration, self intensity descends to some extent.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of preparation not contain the method for the good modified form glass-reinforced plastic material of woven fiber glass shop layer and impact resistance.
The objective of the invention is to be achieved by the following technical programs:
The method that improves glass-reinforced plastic material for preparing provided by the present invention, it may further comprise the steps:
(a) take by weighing the raw material of following weight part ratio: length is 15 ~ 25 parts of the texturized glass yarns of 15 ~ 50mm, 20 ~ 25 parts of Resins, epoxy, epoxide resin reactive diluent 3-8 part, 1 ~ 2 part in 0.05 ~ 0.1 part of softening agent of tackifier, 1 ~ 2 part of silane coupling agent, 2 ~ 5 parts in solidifying agent, 10 ~ 20 parts of fillers;
(b) with texturized glass yarn, under 350 ~ 400 ℃ of temperature, thermal treatment 1-2h removes the residual sizing material oxide compound of fiberglass surfacing;
(c) epoxide resin reactive diluent with 1/3 ~ 1/2 amount adds in the described texturized glass yarn, and is after stirring, standby;
(d) Resins, epoxy, surplus epoxide resin reactive diluent are mixed, add softening agent again, silane coupling agent is prepared into the dipping glue, and is standby;
(e) will go on foot prepared article through c and put into d and go on foot described dipping glue, after stirring, airtight dipping 4-12 hour;
(f) add tackifier, after stirring, adding filler, solidifying agent stir airtight preservation.
When concrete the application, can or be coated with into certain thickness sheet material, solidify, dry 12-24 hour; Or be filled in the mould that scribbles releasing agent, be prepared into the product of desired shape; Or the sealing preservation, in use it is poured in the spray gun, described material is sprayed at the surface that is repaired product carries out reinforcing.
