Description

Non-combustible matrix resin and non-combustible glass fiber reinforced plastic prepared from same
Technical Field
The invention relates to the field of glass fiber reinforced plastics, in particular to a non-combustible matrix resin and a prepared non-combustible glass fiber reinforced plastic.
Background
In general, glass fiber reinforced plastic refers to FRP, and is plastic reinforced with a reinforcing material such as fiber, plastic having mechanical strength, heat resistance, tensile strength, and impact resistance.
The FRP has strong acid, alkali, salt, solvent, seawater and other corrosion resistance, has excellent heat resistance and mechanical strength, and is a semi-permanent material.
Although the FRP has been widely used in the whole industry, the research on the fire resistance of the FRP is relatively insufficient. Particularly in the electronics industry, especially the semiconductor industry, from film or etching processes. Including perfluorinated compounds (PFC), nitrogen, argon, oxygen, hydrogen, ammonia, methane, organic waste gas and the like. Since it is harmful to the human body, it is transferred to an exhaust gas treatment facility through an exhaust pipe or a pipeline. However, the exhaust gas containing combustible gas, purge gas and additive gas is combustible gas, and therefore there is a possibility of fire. Therefore, the exhaust pipes and ducts to be made noncombustible should be made of a noncombustible or very fire-resistant material, and particularly, it is required to have a fire-resistant material that satisfies the FM standard (evaluation standard established according to the industry mutual aid insurance system).
The high-temperature flame retardant property of the glass fiber composite material is limited by the property of the resin matrix. Currently, a high-temperature glass fiber composite material is generally prepared by adding various additives to a high-temperature resin and using glass fibers as a framework. But the structural integrity of the glass fiber composite material taking the phenolic resin as the matrix is greatly reduced after the resin is carbonized when the heating temperature reaches 927 ℃, and the structural integrity is not obviously improved even if the conventional additive is added. Therefore, the conventional phenolic resin-based glass fiber composite material has poor mechanical property and structural integrity after being heated.
CN111518362A discloses a high-temperature flame-retardant glass fiber reinforced plastic and a preparation method thereof, wherein the high-temperature flame-retardant glass fiber reinforced plastic comprises the following raw materials in percentage by weight: 50-60% of glass fiber, 30-45% of silicon modified phenolic resin, 1-3% of aluminum hydroxide and/or magnesium hydroxide, 1-5% of kaolin, 0.1-0.5% of fumed silica and 1-3% of talcum powder. The high-temperature flame-retardant glass fiber reinforced plastic has low resin content, poor chemical resistance (corrosion resistance) and poor acid resistance, and the service life of the high-temperature flame-retardant glass fiber reinforced plastic is influenced because aluminum hydroxide and/or magnesium hydroxide react with an acidic medium to corrode a matrix; the addition of kaolin, fumed silica and talcum powder with solid contents cannot improve the temperature resistance of the matrix. In addition, the high-temperature flame-retardant glass fiber reinforced plastic is only high-temperature flame-retardant and has low fire-retardant grade.
Disclosure of Invention
The invention provides a non-combustible matrix resin, and the non-combustible glass fiber reinforced plastic prepared from the non-combustible matrix resin has the characteristics of non-combustibility and high fire-proof grade, can prevent fire caused by combustible waste gas containing perfluorocarbon, combustible gas, purified gas and the like when exposed to fire and does not catch fire, and overcomes the defect of low grade of high-temperature flame-retardant glass fiber reinforced plastic in the prior art; and has excellent mechanical strength, good heat resistance and durability, and meets FM standard.
The second purpose of the invention is to provide a preparation method of the incombustible matrix resin.
A third object of the present invention is to provide a noncombustible glass fiber reinforced plastic obtained by compounding a noncombustible matrix resin with a fiber fabric and subjecting the resultant to secondary curing, which is incombustible, does not catch fire when exposed to fire, has excellent mechanical strength, has excellent corrosion resistance against acids and alkalis, and also has good heat resistance and durability.
The fourth purpose of the invention is to provide the preparation method of the incombustible glass fiber reinforced plastic, which is to compound and form the incombustible matrix resin and the fiber fabric and carry out secondary curing.
A fifth object of the present invention is to provide an exhaust and/or smoke exhaust duct which can prevent fire caused by flammable exhaust gas containing perfluorocarbon, flammable gas, purified gas, etc.
In order to realize the first purpose of the invention, the invention adopts the following technical scheme:
the non-combustible matrix resin comprises the following raw materials in parts by weight:
Figure BDA0002788318910000021
in the invention, the phenolic resin is thermosetting phenolic resin obtained by catalyzing with strong alkali; because the molecule contains hydroxymethyl with strong reactivity, the polycondensation reaction is easy to occur during production, manufacture and storage, and the resin gradually thickens to be hard and solid. Since the hydroxyl groups on the phenol nucleus are liable to react with alkaline substances to form sodium salts, the alkali resistance is poor. The main component of phenolic resins is phenol formaldehyde, which is a polymer of phenol and formaldehyde. Has the characteristics of high strength of the formed structure and no deformation of high temperature resistance (220 ℃). The modification with furfuryl alcohol can improve the alkali resistance and heat resistance of the thermosetting phenolic resin and prolong the storage life of the thickened phenolic resin.
The furfuryl alcohol molecule contains an active hydroxymethyl group and a furan ring. The furan ring contains double bonds and is a conjugated system, the alpha hydrogen atom is very active under the influence of oxygen atoms, and the addition polycondensation reaction and the double bond polymerization ring opening reaction are easy to occur to form an intermediate compound with high reaction capability in H+The reaction can be continued to form a compact and hard structure under the action of the action or the heating. The furfuryl alcohol belongs to an additive, has better heat resistance than phenolic resin, and can improve the heat resistance temperature by 10-20 ℃ by adding a proper amount of furfuryl alcohol into a phenolic resin matrix, so that the size stability and the electrical property are better; can be mixed with phenolic resin in any proportion, participates in the reaction in the generation or curing reaction of the phenolic resin, and is crosslinked with the molecules of the phenolic resin to form infusible solid matter. Furan rings are introduced into molecules of the phenolic resin, so that the alkali resistance and the heat resistance are improved.
The montmorillonite is a flaky substance with the thickness of 1nm and the length-width ratio of about 2000, and is in a nanometer level. Because the montmorillonite belongs to 2:1 layered silicate, each layer is composed of two silicon-oxygen tetrahedrons and one aluminum-oxygen octahedron which are carried, and the silicon-oxygen tetrahedrons and the aluminum-oxygen octahedrons share oxygen atoms for close packing. In the structure of the montmorillonite, the thickness of each structural unit is about 1nm, the montmorillonite has higher rigidity, and the interlayer is not easy to slide. Al of aluminum octahedron on each surface3+Partial Si in ionic and silicon-oxygen tetrahedron4+By low-valent metal ions, e.g. Mg2+Isomorphous substitution to carry negative charges, and the excess negative charges can be adsorbedInterlayer cations. Na is adsorbed between montmorillonite layers+、K+、Ca2+、Mg2+When water and cation are mixed, they can be easily exchanged with organic cation, so that the surface of montmorillonite can be changed from hydrophilic to hydrophobic, and the montmorillonite can have good compatibility with most of high molecules. Therefore, the montmorillonite and the phenolic resin can be combined in a nanoscale, the advantages of inorganic materials and high polymer materials are integrated, and excellent mechanical property, thermal property, gas barrier property and flame retardance are shown.
Moreover, due to the nanoscale effect of the montmorillonite single-sheet layer, the large specific surface area and the strong interface interaction, strong van der Waals force exists between the polymer chain and the sheet layer, so that some small molecules (oligomers and the like) in the phenolic resin are not easily decomposed in the initial stage of the heating process, and the processing of the phenolic resin in application is facilitated; meanwhile, the decomposition temperature of the phenolic resin is also improved.
The non-combustible glass fiber reinforced plastic prepared by the non-combustible matrix resin integrates the advantages of inorganic materials and high polymer materials, shows excellent mechanical property, thermal property, gas barrier property and flame retardance, and improves the thermal decomposition temperature of phenolic resin.
Further, the non-combustible matrix resin also comprises 1-5 parts by weight of a non-combustible auxiliary agent.
Specifically, the incombustible auxiliary agent comprises one or more of a flame retardant, a smoke retardant or a fire retardant.
More specifically, the flame retardant comprises one or a mixture of two of acid ester TCPP, TDCPP and DEEP; the smoke inhibitor includes but is not limited to MoO3(ii) a The fire retardant comprises but is not limited to one or a mixture of more than two of kaolin, pyrophyllite powder or mica powder.
Further, the diluent is one or more of N, N-dimethylethanolamine, propylene glycol or acrylate; the curing agent is p-toluenesulfonic acid and/or hexamethylenetetramine.
In the invention, the diluent belongs to an additive, and because the phenolic resin matrix is too viscous, the fluidity can be increased by adding a proper amount of the diluent, and the forming in the machining process is facilitated. The curing agent is a catalyst for solidifying the nonflammable base resin and the fiber fabric into a solid form.
In order to achieve the second purpose of the invention, the invention adopts the following technical scheme:

Furthermore, the noncombustible glass fiber reinforced plastic also comprises an anticorrosive coating and a fireproof paint finishing layer, wherein the anticorrosive coating and the fireproof paint finishing layer are arranged on two sides of the noncombustible fiber reinforced layer.

4) and curing the prepared laminated body, and then demolding to obtain the non-combustible glass fiber reinforced plastic.
Further, in the step 4), the curing is a secondary curing, and the secondary curing is firstly curing at room temperature and then curing again in a curing chamber at 50-80 ℃.
It is difficult to cure the above-mentioned incombustible matrix resin (flowable liquid) using a phenolic resin (viscous liquid) as a matrix formulation and other materials. The curing agent mixing reaction at room temperature is only gelation. The solid material with mechanical strength needs to be cured again, and the secondary curing needs to be cured again in a curing chamber environment at 50-80 ℃ to form a stable solid material, namely the non-combustible glass fiber reinforced plastic curing material. This is the forming process necessary to form the incombustible fiberglass reinforced plastic of the present invention, and the incombustible Fiberglass Reinforced Plastic (FRP) prepared by the forming process has incombustible characteristics, and does not catch fire when exposed to fire; can prevent fire caused by combustible waste gas containing perfluorocarbon, combustible gas, purified gas and the like, and is very suitable for exhaust and smoke exhaust pipelines in semiconductor manufacturing processes. Meanwhile, the non-combustible glass fiber reinforced plastic prepared by the non-combustible matrix resin has excellent mechanical strength, excellent corrosion resistance to acid and alkali, good heat resistance and durability, and meets FM standard.
In the invention, the curing temperature of the secondary curing is 50-80 ℃, the curing process is suspended and kept still (for reacting with oxygen in the environment), the duration is 2-6 hours, and the organic waste gas released in the curing process is treated by an exhaust purification system.
In the invention, the glass fiber is one of a surface felt, a chopped strand mat or a glass fiber untwisted yarn.

In the invention, the fire-retardant paint is conventional fire-retardant paint in the field, such as finishing type fire-retardant paint.
Wherein the surfacing mat is a non-woven fabric made of C-type glass monofilaments and has excellent acid resistance and chemical resistance; a chopped strand mat made of short fibers continuously spun from E-type glass, which has excellent strength, electrical insulation and heat resistance; the glass fiber untwisted yarn is formed by uniformly winding filaments into a roll shape, and has a high glass content and excellent mechanical strength.
In the present invention, when glass fibers are laid on the surface of a mold, the glass fibers can be laid on the surface of the mold by a web laying method or a filament winding method.
