Description

A kind of temp, resisting type carbon fibre emulsion sizing agent and preparation method and application
Technical field
The invention belongs to a kind of emulsion type compound that is used to be coated with the charcoal fiber and close sizing agent and preparation method.Said composition can be improved the surface property of going up pulp fibres, can suppress charcoal fiber lousiness in process generation, improve the fiber ABRASION RESISTANCE, the interface that also can improve fiber and matrix resin simultaneously bonds.
Background of invention
Polyacrylonitrile charcoal fiber (PANCF) is a main reinforcing fiber materials of making high-performance composite materials.Because its high specific strength, high ratio modulus and good heat conduction, conduction, performance such as corrosion-resistant make it reinforced composite materials and are used widely in fields such as Aeronautics and Astronautics, industry, building, physical culture.In recent years, along with the development of aerospace industry, require the temperature of 250~350 ℃ of matrix resin abilities, and polyimides (PI) resin etc. can reach this requirement; Therefore resistant to elevated temperatures polymer matrix composites such as CF/PI resin composite materials become the focus of concern.
In production and process, the charcoal fiber is easy to generate lousiness and single wire fracture phenomenon through mechanical friction, and fibre strength is reduced.Because the existence of lousiness also makes matrix resin can not fully soak into the charcoal fiber, cause prepared composite to produce hole, influence the mechanical property of composite.Therefore, must carry out starching to the charcoal fiber handles.
Yan Zhi sizing agent mainly was at the charcoal fibre reinforced epoxy resin composite in the past, opened flat 5-132863 as the spy and made sizing agent with the mixture of epoxy resin-polyurethane resin; Using polyurethane resin and polyether resin among the Te Kaiping 10-266076 is necessary composition, is aided with high-grade aliphatic ester and makes sizing agent; The spy opens among the 2005-179826 to propose to mix by a certain percentage with fatty family polyepoxides and fragrant family polyepoxides and makes sizing agent etc., and all being used for epoxy resin coating is the charcoal fiber of the composite of matrix.And report is seldom arranged at the charcoal fiber sizing agent of polyimide resin composite material, introduced linear polyamidoamine-acid imide with end-blocking and end-blocking not among the U.S.5239046 as the main slurry of composite polyimide material with charcoal fiber sizing agent, but this polyamidoimide needs own polymerization, and operation is more loaded down with trivial details.Having introduced the polyamic acid of fluoridizing among the U.S.4923752 has good adhesive property as sizing agent coated charcoal fiber and polyimide resin, and cost is higher but this fluoridizes polyamic acid.
Summary of the invention
The purpose of this invention is to provide that a kind of cost is low, the temp, resisting type carbon fibre emulsion sizing agent of stable performance and preparation method.
Sizing agent of the present invention is made up of main slurry and auxiliary agent, has added mixed surfactant as auxiliary agent in sizing agent master slurry.In order to make the high-quality charcoal fiber starching emulsion of stable performance, in the mixed aid of the present invention, comprised a certain amount of emulsifying agent.Because carbon fiber surface functional group is hydrophobicity, sizing agent is difficult to timely wetting fiber surface in the starching process, cause slurry not form uniform film at fiber surface, and influence the performance of fiber, therefore also comprise a certain amount of wetting agent in the mixed aid of the present invention, with the effective wettability of improving emulsion and fiber.Because after adding emulsifying agent and wetting agent, emulsion is bubbled easily and caused sizing agent coated inhomogeneous at fiber surface, thereby influences composite property, mixed aid of the present invention also includes the defoamer of trace, to suppress the generation of foam.
Sizing agent of the present invention is made up of main slurry and auxiliary agent, the auxiliary agent quality is 1%~5% of a main stock quality, main slurry by thermoplastic polyimide resin and glycidol ether type epoxy by weight being thermoplastic polyimide resin: the blend of glycidol ether type epoxy=50~90:10~50 is formed, auxiliary agent by emulsifying agent, wetting agent and defoamer by emulsifying agent: wetting agent: the mass ratio of defoamer is that 10~80:10~80:10 forms.
Described thermoplastic polyimide resin is GCPI TM-L1 (below be abbreviated as GCPI) thermoplastic polyimide resin, the glycidol ether type epoxy is E-55, E-51, E-44, E-42, E-35 or E-31 glycidol ether type epoxy.
Described emulsifying agent is sorbitan monostearate polyoxyethylene ether (T-60), alkylphenol polyoxyethylene (OP-7), castor oil polyoxyethylene ether (EL), aliphatic acid and oxirane addition polymers (SE-10) or fatty alcohol-polyoxyethylene ether (O-10); Wetting agent is the mixture (1108) of fatty alcohol-polyoxyethylene ether (JFC), secondary octanol polyoxyethylene ether (JFC-2) or polyoxyethylene and polyethenoxy ether, and defoamer is a silicone defoaming agent.
Preparation method of the present invention is as follows:
At first main slurry is dissolved in the organic solvent, adds auxiliary agent again, be controlled to be at rotating speed under the stirring of 10000~20000rpm, dropwise add a certain amount of deionized water, continue afterwards to stir 30~60min, make white emulsion by main slurry composition.
The mass ratio of described organic solvent and main slurry is 0.5~5:1, and the mass ratio of deionized water and organic solvent is 0.04~0.2:1.
Described organic solvent is dimethyl formamide, dimethylacetylamide or dimethyl sulfoxide (DMSO).
The sizing agent that makes is diluted to 0.1~5wt%, is preferably in 0.5~3wt%.It is poor to be lower than the 0.1wt% starch finishing effect, and the charcoal fiber easily produces lousiness, and it is really up to the mark to surpass the 5wt% fiber, influences processing characteristics.To dilute good sizing agent with infusion process and be attached on the charcoal fiber, dip time is 5~30s, with the fiber after the soaking paste in 100~250 ℃ of following dried 30~200s.100 ℃ of water evaporations of less than are slower, and sizing agent is difficult for dry, are heated apt to deteriorate otherwise surpass 250 ℃ of sizing agents.
Advantage of the present invention is as follows
1, this sizing agent is the emulsion-type sizing agent, and is easy to use, free from environmental pollution;
2, this sizing agent itself can bear higher temperature, and its heat decomposition temperature is about 300 ℃.Be applicable to and the compound preparation composite of fire resistant resins such as polyimides or bimaleimide resin with the coated charcoal fiber of this sizing agent.
3, more starching charcoal fiber lousiness is not few, ABRASION RESISTANCE good with the coated charcoal fiber of this sizing agent, and does not more improve a lot during starching with the interface binding intensity of resin.
