Description
Technical Field
The invention relates to the technical field of composite materials, in particular to a glass fiber reinforced nylon composite material and a preparation method thereof.
Background
Polyamide-6 (PA 6, PA6 for short), Nylon 6(Nylon6), Polycaprolactam (Polycaprolactam), the molecular formula of which is [ -NH- (CH)2)5-CO]nIt is usually made by condensation polymerization of epsilon-caprolactam with a polar amide (-NHCO-) group attached to the chain, where hydrogen can form strong hydrogen bonds with carboxyl groups on different molecular chains.
Nylon6 is a crystalline polymer that is translucent or opaque, milky white in appearance, having a relative molecular mass of between 1.5 and 3 tens of thousands. The nylon6 has excellent self-lubricating property, wear resistance and oil resistance, high mechanical strength, good electrical insulation and good processing fluidity, so that the nylon6 can be widely applied to the industries of automobiles, traffic, chemical engineering, machinery, instruments, agricultural machinery, textile machinery and the like. However, nylon6 has a high water absorption rate, so that the nylon6 generates a plasticizing effect to a certain extent, and thus the stability of the product is poor and the heat resistance needs to be improved.
Glass fiber (GF for short) has low water absorption, good heat resistance, corrosion resistance, heat insulation, electrical insulation, high tensile strength, high elastic modulus, and small elongation (less than 3%). The glass fiber is mainly used as an electrical insulating material, an industrial filtering material, an anticorrosion, dampproof, heat-insulating, sound-insulating and shock-absorbing material, and can also be used as a reinforcing material to manufacture products such as reinforced plastics, reinforced rubber, reinforced gypsum, reinforced cement and the like.
The glass fiber can be divided into alkali glass fiber (the content of alkali metal is more than 12%), medium alkali glass fiber (the content of alkali metal is 6-12%), low alkali glass fiber (the content of alkali metal is 2-6%) and alkali-free glass fiber (the content of alkali metal is less than 2%) according to the content of alkali metal oxidation in the fiber; the glass fiber can be divided into coarse fiber (monofilament diameter is 30 μm), primary fiber (monofilament diameter is 20 μm), middle grade fiber (monofilament diameter is 10-20 μm), high grade fiber (monofilament diameter is 3-9 μm), and superfine fiber (monofilament diameter is less than 4 μm) according to diameter size; glass fibers can be classified into continuous fibers, chopped fibers, hollow glass fibers, milled fibers and glass powder according to appearance.
The modification of nylon mainly comprises physical modification and chemical modification, wherein the chemical modification is to add other monomers in the polymerization reaction process and copolymerize to prepare copolymerized nylon; the physical modification is generally to add some modifiers with filler properties (such as fillers, lubricants, reinforcing materials, coupling agents, flame retardants, etc.) and blend the modifiers with nylon to obtain modified nylon. The composite material obtained by adding glass fiber into nylon is a common nylon modified material, and the material has good strength, heat resistance, excellent impact resistance, dimensional stability, low warpage and the like, but the material still has the following defects: firstly, when the mixture of the glass fiber and the nylon6 is extruded and processed, the glass fiber which is cut into fragments is uniformly distributed in the nylon6, so that the fluidity of the composite material is limited to a certain extent when the composite material is extruded and processed, and the processing and forming difficulty of the composite material is increased; secondly, when some nylon products are used, the high mechanical property and the good thermal stability of the nylon products are required, and even the mechanical property, the thermal stability, the corrosion resistance and the like of the nylon products under comprehensive environmental conditions are required, for example, the composite material is required to resist the erosion of oil agent under the high-temperature condition, so the improvement of the glass fiber reinforced nylon composite material is still required.
Disclosure of Invention
The first technical problem to be solved by the present invention is to provide a glass fiber reinforced nylon composite material, which can not only reduce the processing and forming difficulty of the glass fiber reinforced nylon composite material, but also has good corrosion resistance in a high-temperature oil-heat environment.

The interface formed by the contact of the glass fiber and the nylon resin matrix in the glass fiber reinforced nylon composite material is a new phase which has a certain thickness, a structure similar to that of the nylon resin matrix and is obviously different from the glass fiber, and the new phase is called as an interface phase. According to the research, the interface phase is a 'tie' connecting the glass fiber and the nylon resin matrix, the interface plays a role in transferring stress, and the strength of the transferring function is determined by the bonding strength of the interface. If the interface strength is large enough and the transmission efficiency of the stress is high, the strength of the composite material is improved more; however, if the interfacial strength is weak, even lower than that of the resin, the strength of the composite material may be lower than that of the pure resin.

The addition of the antioxidant can ensure that the processed glass fiber reinforced nylon composite material still has good color and luster and performance.

The product name of the N, N' -bis- (3- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionyl) hexamethylenediamine is antioxidant 1098, the antioxidant 1098 is a special antioxidant for nylon6, the molecular structure of the antioxidant is good in compatibility with the nylon6, and the viscosity of the nylon6 can be stabilized in the processing process. The product name of the phosphorous acid tri (2, 4-di-tert-butylphenyl) ester is antioxidant 168, the antioxidant 168 is an auxiliary antioxidant, and the effect is better when the antioxidant is combined with antioxidant 1098.
More preferably, in order to make the glass fiber reinforced nylon composite material have better corrosion resistance in a high-temperature oil thermal environment, the content of the nylon6 is 69.7%, the content of the glass fiber is 25%, the content of the auxiliary agent is 3%, the content of the cardanol epoxy compound is 2%, and the content of the antioxidant is 0.3%.
