Description
The invention belongs to field of compound material, is a kind of flame-retardant glass fibre reinforced plastic materals that is used for civilian aircraft cabin interior trim.
Modern civilian aircraft cabin inner decoration material generally all adopts glass fibre enhanced polymer matrix composites, because security needs, this material must have fire-retardant and low smoke generation characteristics, also should have enough intensity and good moulding process simultaneously.According to the domestic and foreign literature report, used flame-retardant glass fibre reinforced plastic materals has two classes at present: a class is that fire retarding epoxide resin is the material of matrix, contains halogen, though flame retardant resistance is good, the rate of being fuming is very high, and smog toxicity is big, promptly belongs to this type of as U.S. Pat 4178408; Another kind of is that resol is the material of matrix, and flame retardant resistance is better, and the rate of being fuming is lower, but, therefore, must use the moulding of high-pressure process ability owing to have small molecules to separate out in the solidify reaction process, bring very big difficulty for the more complicated shape structure of the manufacturing relatively large shape of volume, as U.S. Pat 4112188.In addition, this two classes material all contains and the insoluble flame retardant resistance inoganic solids of resin fleut usually, causes the mechanical property of flame retardant glass fiber reinforced plastic all lower.
The objective of the invention is to overcome the deficiency of above-mentioned materials, provide a kind of flame retardant properties good, the rate of being fuming is low, physical strength height, and the glass-reinforced plastic material of the enough low-pressure process moulding of energy.
Main points of the present invention are that the flame-retardant glass fibre reinforced plastic materals that is provided is a strongthener with E-glass, are body material with F-15 novolac epoxy, FB-boron bakelite resin, new phenol II-poly-pheno-ether resin, and imidazoles is a catalyzer, and is formulated by a certain percentage.
Key of the present invention is to have adopted the main body component of the higher F-51 novolac epoxy (structural formula is seen accompanying drawing 1-a) of good fluidity and phenyl ring content as body material; (structural formula sees that Fig. 1-b) and new phenol-II gather pheno-ether resin (structural formula is seen accompanying drawing 1-c) as curing agent for epoxy resin to adopt the good and extraordinary FB-boron bakelite resin of flame retardant properties of thermo-oxidative stability.Make this system have good flame-retarding characteristic and the low rate of being fuming under the situation that need not add halogen and inoganic solids powder, no small molecules is separated out in the solidify reaction process, but low pressure molding.In addition, be catalysts owing to adopt imidazoles, can make this system in that to be lower than 150 ℃ of following curing reactions complete.
Implementing compound method of the present invention is:
With acetone is solvent, adds the F-51 novolac epoxy, the FB-boron bakelite resin, and the poly-pheno-ether resin of new phenol-II, materials such as imidazoles, each component concentration is:
F-51 phenolic aldehyde epoxy 100(weight) part; 40～50 parts in FB-boron phenolic aldehyde; 50～60 parts of the poly-pheno-ether resins of new phenol-II, 0.8～2 part of imidazoles.The weight ratio of acetone and resin is 1.5: 1.Strongthener E-glasscloth gives with gluing method preparation and to soak material, gives soaking that resin content is 30～35%(weight fraction in the material).
The pressing process of glass reinforced plastic can adopt thermocompressor or hot pressing tank pressure system, and low pressure molding once adds total head 0.7～1MPa, keeps 4 hours down at 150 ℃, naturally cools to room temperature.
Introduce two specific embodiments of the invention below:
One of embodiment: will: F-51 novolac epoxy 100 grams
FB-boron bakelite resin 50 grams
Poly-pheno-ether resin 60 grams of new phenol-II
Room temperature is dissolved in industrial acetone 317 grams
0.2mm the prepreg resin content of the manual gluing preparation of thick E-glass fibre plain (KH-560 surface treatment) is 31%, thermocompressor compacting, low pressure molding once add total head 0.7MPa, keep 4 hours down at 150 ℃, naturally cool to room temperature.Technological process is seen accompanying drawing 2.
The flame retardant glass fiber reinforced plastic performance of pressing the present embodiment preparation is as follows:
Oxygen index 42(GB2406-80)
Vertical combustion 17 seconds (UL-94 V-0)

Interlaminar shear strength 53.9MPa(GB14501-83)
Shock strength 172KJ/m
2(GB14501-83)
The resin matrix thermogravimetic analysis (TGA) shows, rises to 700 ℃ of (20 ℃/minute of heat-up rates) residual carbon amounts 65% by room temperature, proves that this system rate of being fuming is little.
Two of embodiment: will: F-51 novolac epoxy 100 grams
FB-boron bakelite resin 40 grams
Poly-pheno-ether resin 50 grams of new phenol-II
Imidazoles 0.8 gram
Room temperature is dissolved in industrial acetone 286 grams
0.2mm the prepreg resin content of the manual gluing preparation of thick E-glass fibre plain (KH-560 surface treatment) is 32.7%, autoclave compacting, low pressure molding once add total head 1.0MPa, keep 4 hours down at 150 ℃, naturally cool to room temperature.Technological process is seen accompanying drawing 3.
The flame retardant glass fiber reinforced plastic performance of pressing the present embodiment preparation is as follows:
Oxygen index 41(GB2406-80)
Vertical combustion 17 seconds (UL-94 V-0)
Tensile strength 497MPa(Gb1449-83)
Tensile modulus 31.0GPa(GB1449-83)
Flexural strength 509MPa(GB1449-83)
Interlaminar shear strength 60.7MPa(GB14501-83)
Shock strength 239KJ/m
2(GB14501-83)
The resin matrix thermogravimetic analysis (TGA) shows, rises to 700 ℃ of (20 ℃/minute of heat-up rates) residual carbon amounts 63.5% by room temperature, and the rate of being fuming is little.
Characteristics of the present invention are that the flame-retardant glass fibre reinforced plastic materals fire resistance is good, and the rate of being fuming is low, and are not halogen-containing, do not contain the anti-flammability solid packing insoluble with matrix. Because no little molecule in the change course of reaction is separated out available low-pressure process moulding. Fiberglass intensity height, good toughness are a kind of civil aircraft cabin inner decoration materials of high comprehensive performance. This material also can be used as the inner decoration materials such as automobile, train, steamer, submarine and senior building. Abundant raw material, preparation and compacting are simple, cost is lower, have significant economic benefit and social benefit.
