Technical field
The present invention relates to technical field of polymer materials, a kind of method of spontaneous heating bulbs of pressure bag forming resin fibre composite.
Background technology
Resin fibre composite refers to using thermosetting resin as binding agent, fiber is as the material of reinforcement, a kind of new material that resin and fiber obtain after being mutually bonded curing molding, resin can be epoxy resin, unsaturated-resin, polyester resin etc., fiber can be glass fibre, carbon fiber, aramid fiber etc., it is generally required to liquid resin will carry out laying by required form after fiber moistening again, general forming method has: the methods such as hand pasting forming, built-in airbag molding, vacuum pressure jug forming.
The airbag method of forming is a kind of critically important forming method of resin composite materials, it is mainly used in some high-intensity hollow products of molding, such as bicycle girder, racket etc., traditional moulding process is that by certain laying direction, prepreg is laid molding in advance, again airbag is together put into mould with the prepreg completed, matched moulds, pour hot-air again, prepreg is adjacent to mould resolidification molding by hot-air air pressure, the demoulding, finishing, polishing, surface processes and obtains finished product, this forming method is limited by the complexity of product, if the molding difficulty of shape of product complexity higher side face airbag increases, if on the other hand inner chamber complexity airbag can cause product defects to the pressure unbalanced airbag easily breakage of inwall.The most traditional airbag method of forming is that when product solidifies, whole system is that the situation of being heated is from outside to inside by heated succession: mould prepreg airbag, this defect by hot mode is, at die surface and first solidify by bag side prepreg and solidify air after the prepreg at middle part and can not discharge this heat differential in time product can be caused local cavity or defect occur.Therefore being that product is heated from a direction and transmits to other direction for curing mode optimal from the point of view of composite molding, unnecessary resin also can be discharged increase fiber and the ratio of resin, it is possible to by removal of bubbles, the defect reducing goods increases the performance of goods.
Summary of the invention
It is an object of the invention to: a kind of method providing spontaneous heating bulbs of pressure bag forming resin fibre composite, its good forming effect, technique is simple, with low cost, to overcome the deficiencies in the prior art.
The present invention is achieved in that the method for spontaneous heating bulbs of pressure bag forming resin fibre composite, expandable microspheres foaming agent is inserted in airbag to be formed, expandable microspheres foaming agent is made to expand by adding microspheres foaming agent, thus it is swollen to replace source of the gas to rush airbag, finally make airbag molding in a mold.
Described heating is specifically, by volume number calculates, 30-40 part quick lime it is mixed into uniformly in 30-40 part expandable microspheres foaming agent, again mixture is together put in mould with the idiosome with shape of product made with prepreg, in airbag, add 20-30 part water after matched moulds, make quick lime generate heat to 80-140 DEG C.
1.9-3.4 part lubricant it is additionally provided with in expandable microspheres foaming agent.
The expandable microspheres foaming agent of the present invention is that a kind of being provided with in elastic capsule can the drop (only 10-50 μm) of expanded by heating, may expand to 50-100 times of initial volume at a certain temperature, owing to it is the most self-existent independent source of the gas entity, thus to no requirement (NR) of whether leaking gas from the point of view of elastic airbag, even if gas leakage also can realize rushing airbag swollen, and could be expanded foamed when expandable microspheres is only heated.
Owing to have employed technique scheme, compared with prior art, a kind of new method that this method of the present invention designs in the defect made existing for complexity for tradition airbag moulding process, it uses expandable microspheres foaming agent to replace source of the gas, use quick lime and water to react generation thermal source, also can absorb moisture while that quick lime and water reacting and avoid the impact that resin is solidified by moisture.Owing to quick lime and expandable microspheres foaming agent are at same intracavity, quick lime and water react generated heat and can not distribute in time and thermal-arrest in inner chamber, the expandable microspheres foaming agent of intracavity starts foaming after being heated makes internal prepreg be close to mould, the rising of cavity temperature makes resin viscosity diminish, prepreg is extruded unnecessary resin extruded by foaming agent pressure, thus has reached the purpose of further minimizing resin；Due to thing filled out in inner bag is powder body can be through the of short duration response time when calcium oxide meets with moisture, it is to avoid in inner bag, inflate that local air flow is excessive and that cause airbag ruptures, gas expansion slow airbag wall Compression Stability in bag, product inner wall smooth.Expanded material has good fillibility in inside, and around the corner or other key position can well fill the compactness adding product.Like products employing dilatometry not only can reduce the formed product time and improve product compactness simultaneously.Selected expandable microspheres foaming agent foam multiplying power is high, can produce when internal cavity foam enough pressure and can pressurize for a long time, be still powder body simultaneously after expandable microspheres foaming agent foam, facilitate and draw out from inner chamber.The present invention is simple, material source is extensive, with low cost, using effect is good.
